Technical Field

[0001] The utility model belongs to the technical field of new energy charging plugs, in particular to a new energy charging protection plug. Background Art

[0002] New energy charging plugs are mainly installed on charging piles and are used to charge electric vehicles. With the popularization of electric vehicles, electric vehicle charging stations will inevitably become the focus of the development of the automotive industry and the energy industry. New energy charging plugs can better solve the problem of fast charging.

[0003] The charging plug is often inserted into a charging pile. When in use, it is taken out to charge the electric vehicle. In the process of taking out the charging plug and inserting it into the electric vehicle, or pulling out the charging plug from the electric vehicle and reinserting it into the charging pile, the charging plug is exposed to the outside world. Therefore, when it rains, rainwater is likely to stick to the outer surface of the charging plug. When the charging plug is connected to the charging pile or the electric vehicle, rainwater will be brought in together. Over time, some metal components will be corroded by rainwater, thereby reducing the safety of charging. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 3 As shown, the utility model provides a new energy charging protection plug, including a charging plug housing 1 and a charging plug body 2, and also includes:

[0022] A water removal structure, which is arranged on the charging plug housing 1 and is used to remove rainwater on the surface of the charging plug body 2;

[0023] Among them, the water removal structure includes a first cavity 3 and a second cavity 12, the first cavity 3 and the second cavity 12 are arranged inside the charging plug shell 1, and also include a second notch 9 and a heat dissipation port 11, the second notch 9 is arranged at the end of the charging plug shell 1, and the heat dissipation port 11 is arranged on both sides of the charging plug shell 1, the interior of the first cavity 3 is sleeved with a first magnet 4 and a first spring 5, a connecting shaft 6 is installed on one side of the first magnet 4, a mounting plate 7 is installed on one end of the connecting shaft 6, and a sleeve 8 is installed on the outer side of the mounting plate 7, the interior of the second notch 9 is inlaid with absorbent cotton 10, the interior of the second cavity 12 is sleeved with a second magnet 13 and a second spring 14, one side of the second magnet 13 is installed on a pull rod 15, one end of the pull rod 15 passes through the charging plug shell 1 and is installed with a buckle 16.

[0024] Through the cooperation between the first magnet 4 and the first cavity 3, when the charging plug body 2 is plugged into the electric car, the sleeve 8 will move along the outer surface of the charging plug body 2 and scrape off the rainwater on the outer surface of the charging plug body 2. At the same time, the second magnet 13 adsorbs the first magnet 4 to limit the movement of the sleeve 8. After the sleeve 8 enters the second slot 9, the remaining rainwater will be absorbed by the absorbent cotton 10. During the charging process of the charging plug body 2, it will generate heat, and the heat will evaporate the water stains inside the absorbent cotton 10, so that the evaporated water vapor can be discharged through the heat dissipation port 11, thereby preventing the rainwater from corroding the electronic components.

[0025] The sleeve 8 is sleeved with the charging plug body 2 , and the inner wall of the sleeve 8 is bonded with rubber.

[0026] Through the rubber bonded to the inner wall of the sleeve 8 and the cooperation between the sleeve 8 and the charging plug body 2, water stains on the surface of the charging plug body 2 can be scraped off through the sleeve 8. At the same time, the rubber has an insulating effect, thereby improving its safety.

[0027] When the sleeve 8 moves, it can be sleeved with the second notch 9 , and the sleeve 8 is in compression contact with the absorbent cotton 10 .

[0028] Through the cooperation between the sleeve 8 and the second slot 9, the sleeve 8 will fit with the absorbent cotton 10 when entering the second slot 9, so that part of the scraped water stains can be pushed into the position of the absorbent cotton 10, and the absorbent cotton 10 can absorb the water stains.

[0029] The first spring 5 is elastically supported between the first cavity 3 and the first magnet 4 .

[0030] The design of the first spring 5 allows the first magnet 4 to have good elastic reset performance. At this time, since the first spring 5 is in a compressed state, an elastic force is applied to the first magnet 4, so that the mounting plate 7 can be driven by the connecting shaft 6 to reset the sleeve 8.

[0031] One end of the second magnet 13 passes through the second cavity 12 and extends to the inside of the first cavity 3 , and the second spring 14 has the same magnetic pole as the side adjacent to the second magnet 13 .

[0032] Through the cooperation between the first magnet 4 and the second magnet 13, the movement of the first magnet 4 can be restricted. At the same time, the pull rod 15 can be pulled by the pull buckle 16 to separate the second magnet 13 from the first magnet 4, thereby releasing the limit on the first magnet 4. At this time, due to the elastic force of the first spring 5, the connecting shaft 6 will be driven by the first magnet 4 to reset the sleeve 8. After the sleeve 8 is reset, a thrust will be applied to the electric vehicle or the charging pile to drive the charging plug body 2 to separate from the electric vehicle, so it is more labor-saving when pulling out the charging plug body 2.

[0033] The heat dissipation port 11 is connected to the second slot 9 and the position of the heat dissipation port 11 corresponds to the absorbent cotton 10 . The tail of the charging plug housing 1 is connected to a power cord 17 , which is connected to an external charging pile.

[0034] Through the cooperation between the heat dissipation opening 11 and the second notch 9 , the moisture inside the water-absorbing cotton 10 will be emitted through the heat dissipation opening 11 after being heated.

[0035] The working principle and use process of this utility model:

[0036] First, when the charging plug body 2 is inserted into the electric vehicle, the sleeve 8 will move along the outer surface of the charging plug body 2 and scrape off the rainwater on the outer surface of the charging plug body 2. After the sleeve 8 moves, the connecting shaft 6 will move along the inside of the first cavity 3 and drive the first magnet 4. At the same time, the second magnet 13 adsorbs the first magnet 4 to limit the movement of the sleeve 8. After the sleeve 8 enters the second slot 9, the remaining rainwater will be absorbed by the absorbent cotton 10. During the charging process of the charging plug body 2, it will generate heat by itself, and the heat will evaporate the water stains inside the absorbent cotton 10, so that the evaporated water vapor can be discharged through the heat dissipation port 11, thereby preventing rainwater from corroding electronic components.
