Description

Technical Field

[0001] The invention relates to the technical field of direct current liquid-cooled charging sockets, and in particular to a direct current liquid-cooled charging socket with a lighting function. Background Art

[0002] As a new energy vehicle, electric vehicles have the advantages of low pollution, low noise, and energy conservation. They can replace traditional vehicles to solve the problems of energy shortage and environmental pollution. Electric vehicles are increasingly used in life, and the charging equipment such as charging guns used with them are also developing rapidly.

[0003] At present, the charging process of electric vehicles is also very simple. Park the car in the charging area of ​​the charging pile, pull the gun from the charging pile and insert it into the car charging port for charging. After charging, insert the gun head back into the charging pile. However, if charging is carried out at night or in dark places such as underground garages, in the absence of lighting, it will cause charging operations to be difficult. Due to the dim light, on the one hand, the charging plug cannot be accurately inserted into the charging socket of the electric vehicle, and the owner needs to use a mobile phone or other light source for lighting, which is more troublesome; on the other hand, when there is a foreign object in the gun head or socket of the charging gun, it is inconvenient to check and remove the foreign object in time. If a human operating error occurs, there will be a risk of electric shock, which will not only poor the user experience, but also affect the safety of the entire vehicle. Summary of the invention

[0014] See also Figure 1-2 The present invention provides a technical solution: a DC liquid-cooled charging socket with lighting function, comprising a charging gun body 4, a lighting lamp 2 is provided on one side of the charging gun body 4, a plurality of charging terminal heads 42 are provided in the inner cavity of the charging gun body 4, a charging socket shell 41 is provided on the outer edge of the charging gun body 4, and a control circuit is provided in the charging gun body 4;

[0015] The control circuit includes a plurality of lighting lamps 2, a plurality of reed switches 1, a current limiting resistor 3 and a power supply. The lighting lamps 2 are connected in parallel with the reed switches 1, connected in series with the current limiting resistor 3, and then connected in series with the power supply to form a loop.

[0016] The purpose of setting the current limiting resistor 3 is to protect the power supply when the reed switch 1 is in the closed state. The control circuit has two conduction states, wherein the lighting lamp 2 is connected in parallel with the reed switch 1. If the reed switch 1 is a normally open switch, when the reed switch 1 contacts the external magnetic field, the external magnetic field causes the reed contact part of the reed switch 1 to be attracted by the magnetic force. When the attraction is greater than the elastic force of the reed, the normally open contact will be attracted. At this time, the reed switch 1 changes from the normally open state to the closed state, and forms a loop with the current limiting resistor 3, so that the lighting lamp 2 is short-circuited. Thereby, the lighting lamp 2 is turned off; when the reed switch 1 leaves the external magnetic field, the normally open contact reopens, and the reed switch 1 changes from the closed state to the normally open state, and the lighting lamp 2 and the current limiting resistor 3 form a circuit to turn on the lighting lamp 2; multiple reed switches 1 are provided, and multiple reed switches 1 are connected in parallel. If one of the reed switches 1 is damaged, the other reed switches 1 can be used normally; multiple lighting lamps 2 are provided, and multiple lighting lamps 2 are connected in parallel. If one of the lighting lamps 2 is damaged, the other lighting lamps 2 can be used normally; multiple lighting lamps 2 can also enhance the light intensity;

[0017] The lighting lamp 2 is an LED lamp and a ring light. The lighting lamp 2 uses an LED lamp, which has good light intensity and energy-saving effect. At the same time, the LED lamp has a good service life and stability, avoiding frequent replacement;

[0018] The lighting lamp 2 is installed in a mounting hole arranged near the top of the charging socket housing 41, and the reed switch 1 is installed in a mounting hole arranged on the side wall around the charging terminal 42, and the reed switch 1 is a normally open switch;

[0019] Multiple reed switches 1 are evenly distributed on the side wall around the charging terminal 42. The evenly distributed reed switches 1 are beneficial for evenly inducing the magnetic field when the charging terminal 42 is close to the vehicle charging terminal plug interface or the charging pile plug interface, thereby switching the open and closed states of the reed switches 1.

[0020] Working principle: When the charging socket is not in use (locked to the charging pile) or in a locked charging state, the reed switch 1 will provide a magnetic field provided by a magnet close to the charging pile plug interface or the vehicle charging end plug interface. Due to the effect of the magnetic field, the two reeds of the reed switch 1 attract each other and close. At this time, the reed switch 1 is in a closed state and forms a loop with the current limiting resistor 3, so that the lighting lamp 2 is short-circuited and the lighting lamp 2 is turned off. That is, when the charging socket is not in use or is connected to the charging gun in a charging locked state, the lighting lamp 2 is not on, which is beneficial to saving energy consumption; when the charging gun body 4 When it is needed or after use, the reed switch 1 will leave the external magnetic field and the normally open contact will reopen. At this time, the reed switch 1 changes from a closed state to a normally open state, and the lighting lamp 2 and the current-limiting resistor 3 form a circuit to turn on the lighting lamp 2. With the help of the light emitted by the lighting lamp 2, it is convenient to check the position of the vehicle charging terminal plug interface, or whether the plug interface has foreign objects or damage that may cause safety problems. It is convenient to insert the charging gun body 4 into the vehicle charging terminal plug interface for charging when the light is dim, and it is also convenient to put the charging gun body 4 back into the charging pile after use.
