Description

Charging pile socket structure

technical field

The invention relates to a charging pile, in particular to a structure of a charging pile insertion port.

Background technology Environmental pollution and energy shortage are increasingly becoming severe issues that must be faced in my country's sustainable development and building a harmonious society. In order to meet the above challenges, green, environmental protection, and energy saving have become popular topics in today's society. In order to improve the quality of development, the government also actively encourages various industries to develop energy-saving and environmentally-friendly products. Therefore, environmental-friendly and energy-saving products are full of vitality in today's society and are a new source of economic growth. As a green vehicle that effectively replaces fuel vehicles, electric vehicles need a big development in the future, both from the perspective of environmental protection and energy.

Faced with a large number of electric vehicles, the battery life is very limited due to the use of lead-acid batteries or lithium batteries. Usually, it must be charged after driving for one to three days, and it often happens that the electric vehicles are parked due to insufficient power on the road. The phenomenon of promotion, so the electric vehicle charging pile came into being. However, at present, there is no standard charging place for electric vehicle charging in almost all residential areas. Basically, the charging is carried out by putting wires from the outer wall of the building to the first floor of each household, and connecting them privately, which greatly increases the safety and reliability of power use. The rate of safety accidents increases accordingly; and the existing outdoor charging piles are seriously affected by external environmental factors. Usually, in rainy days or on special road sections, there will be water or a large amount of dust at the interface of the charging piles, causing the charging piles to be damaged. The service life of the charging pile is reduced, and in severe cases, it will cause a short circuit or even direct damage to the charging pile.

Contents of the invention

The purpose of the present invention is to provide a charging pile plug-in port structure, to ensure the safety of the charging pile interface, and to prevent rainwater or dust and other sundries from entering the charging interface.

The object of the present invention is achieved through the following technical solutions:

The charging pile plug-in structure includes a housing covering the charging interface and an arc-shaped cover plate rotatably arranged on the housing. Clamping columns are fixed at both ends of the cover plate, and the bottom of the movable end of the cover plate is set There is a baffle, and the housing is provided with a clamping seat matching the clamping column and a limit block that can cooperate with the baffle. The limit block is provided with a dovetail groove, and the middle part of the dovetail groove is fixed with a A tapered column, two elastic feet with a trapezoidal cross-section are installed on the end of the baffle, and a cavity matching the tapered column is formed between the two elastic feet; two acute-angled triangular blocks are also included, The longest sides of the two acute-angled triangular blocks are respectively connected to the two side walls of the dovetail groove. When the cover plate seals the charging interface, the positions of the baffle plate and the dovetail groove are configured such that after the elastic legs enter the dovetail groove Its outer wall moves relative to the hypotenuse of the acute-angled triangular block, and at the same time, the two elastic legs are squeezed by the two acute-angled triangular blocks to move closer to the tapered column.

After the electric vehicle is fully charged, press down the cover plate so that it completely covers the entire charging interface, so that the clamping post and the clamping seat cooperate with each other, and then complete the sealing of the charging interface to prevent external dust or rainwater from entering. In the charging interface, the stable use of the charging pile is guaranteed; when the invention works, when the cover plate seals the charging interface, the positions of the baffle plate and the dovetail groove are configured such that the outer wall of the elastic leg enters the dovetail groove and the acute angle triangle The hypotenuses of the blocks move relative to each other, and the inner wall of the cavity slides down along the outer wall of the tapered column to provide guidance for the movement of the cavity. At the same time, the two elastic legs are squeezed by the two acute-angled triangular blocks to move closer to the tapered column. After being squeezed and deformed, the elastic legs will return to the deformation and produce a force in the opposite direction on the acute triangle, so that the baffle is clamped in the dovetail groove, so that the cover is locked at the charging interface, preventing charging near the charging pile. Children wantonly open the cover due to playing, avoiding electric safety accidents and improving the safety of charging piles.

Further, the cavity has a trapezoidal cross section, and the outer diameter of the smallest end of the tapered column is greater than the inner diameter of the smallest end of the cavity. When the cavity slides down the outer wall of the tapered column, the overall size of the tapered column is larger than the space inside the cavity, so that when the elastic foot moves down, the tapered column expands the space inside the cavity, and then the elastic foot A pressure in a direction opposite to the direction of the force exerted by the acute-angled triangular block on the elastic leg is generated, so that the elastic leg is stably clamped in the dovetail groove, ensuring the sealing performance of the cover plate to the charging interface.

Further, a drainage channel is also included, and the drainage channel is arranged at the bottom of the casing and faces the center of the baffle. When it rains or when there is a vehicle driving on the roadside and the liquid splashes onto the cover, the baffle and the limit block will drain the rainwater to the bottom of the housing, and finally flow out of the charging pile through the drain to prevent rainwater from flowing into the charging port and causing damage. The short circuit of the charging pile is damaged.

Compared with the prior art, the present invention has the following advantages and beneficial effects:

1. In the present invention, when the cover plate seals the charging interface, the positions of the baffle plate and the dovetail groove are configured such that after the elastic leg enters the dovetail groove, its outer wall moves relative to the hypotenuse of the acute-angled triangular block, and the inner wall of the cavity Slide along the outer wall of the tapered column to provide guidance for the movement of the cavity. At the same time, the two elastic legs are squeezed by the two acute-angled triangular blocks to move closer to the tapered column. The elastic legs will recover after being deformed after being squeezed Furthermore, a force in the opposite direction is generated on the acute triangle, so that the baffle is clamped in the dovetail groove, so that the cover is locked at the charging interface, preventing children near the charging pile from opening the cover arbitrarily due to playing, and avoiding power safety. Accidents, improve the safety of charging piles;

2. In the present invention, when the cavity slides down the outer wall of the tapered column, the overall size of the tapered column is larger than the space inside the cavity, so that when the elastic legs move down, the tapered column expands the space inside the cavity, Furthermore, a pressure in a direction opposite to that of the force exerted by the acute-angled triangular block on the elastic leg is generated on the elastic leg, so that the elastic leg is stably clamped in the dovetail groove, ensuring the sealing performance of the cover plate to the charging interface.
