Description

Technical Field

[0001] The present invention relates to the technical field of charging sockets, and in particular to a charging socket with a lighting function and a control method thereof. Background Art

[0002] As a kind of 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 widely used in life, and the charging equipment such as charging guns used with them have also developed rapidly. 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 plug it into the car charging port for charging. After charging, plug 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. 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 charging gun head or socket, it is not convenient to check and remove the foreign object in time. If there is a human error in operation, there will be a risk of electric shock, which will not only have a poor user experience, but also affect the safety of the entire vehicle. Summary of the invention

[0005] Preferably, the charging socket is provided with a plurality of reed switches, and the plurality of reed switches are evenly distributed on the side wall around the end of the charging socket.

[0006] The present invention also provides another technical solution: a control method for a charging socket with a lighting function, wherein the control circuit includes a lighting lamp, a reed switch, a current limiting resistor and a power supply, wherein the lighting lamp is connected in parallel with the reed switch, connected in series with the current limiting resistor, and then connected in series with the power supply to form a loop.

[0015] See also Figure 1-2 , the present invention provides a technical solution:

[0016] Embodiment 1:

[0017] A charging socket with lighting function, comprising a charging socket body and a lighting indication control circuit arranged in the charging socket body, a lighting lamp 2 is installed in a mounting hole arranged near the top of the charging socket shell 41; a reed switch 1 is installed in a mounting hole arranged on the side wall around the charging end head 42 of the charging gun; the reed switch 1 is a normally open switch, a charging gun body 4 and a lighting indication control circuit arranged in the charging gun body 4, the lighting lamp 2 is installed in a mounting hole arranged near the top of the shell of the charging gun socket end, the reed switch 1 is installed in a mounting hole arranged on the side wall around the charging end head 42 of the charging gun, and the reed switch 1 adopts a normally open switch. This embodiment is applicable to vehicles or charging piles with magnets provided on the vehicle charging end plug interface and the charging pile plug interface matching the charging gun. The working principle and process of this embodiment are as follows: 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 arranged 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 needs to be used (that is, from the charging gun), the charging gun 2 is turned off. When the charging gun is removed from the charging pile) or after use (i.e., when the charging gun is removed from the vehicle charging end socket), 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 illuminating lamp 2 and the current limiting resistor 3 form a circuit to turn on the illuminating lamp 2. With the help of the light emitted by the illuminating lamp 2, it is convenient to check the position of the vehicle charging end socket, or whether there are foreign objects or damage in the socket, which may cause safety problems. It is convenient to smoothly insert the charging gun into the vehicle charging end socket for charging when the light is dim, and it is also convenient to put the charging gun back into the charging pile after use;

[0018] The charging socket is provided with a plurality of reed switches 1, which are evenly distributed on the side wall around the end of the charging socket. A plurality of reed switches 1 are provided, and the plurality of 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. In addition, the evenly distributed reed switches 1 are conducive to evenly inducing the magnetic field when the charging end of the charging gun is close to the vehicle charging end plug interface or the charging pile plug interface, and switching the open and closed states of the reed switches 1.

[0019] Embodiment 2:

[0020] A control method for a charging socket with lighting function, the control circuit includes a lighting lamp 2, a reed switch 1, a current limiting resistor 3 and a power supply, the lighting lamp 2 is connected in parallel with the reed switch 1, then connected in series with the current limiting resistor 3, and then connected in series with the power supply to form a loop, the lighting lamp 2 used for lighting the charging socket and the reed switch 1 are connected in parallel, and then connected in series with the current limiting resistor 3 and the power supply to form a loop. The purpose of setting the current limiting resistor 3 is to protect the power supply when the reed switch 1 is in a closed state. The control circuit has two conduction states, in which 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 an external magnetic field, the external magnetic field causes the reed contact part of the reed switch 1 to be attracted by 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 a normally open state to 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; when the reed switch 1 leaves the external magnetic field, the normally open contact is reopened, and 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 loop to turn on the lighting lamp 2.

[0021] The reed switch includes a plurality of reed switches 1 , and the plurality of 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.

[0022] The lighting lamps 2 include multiple lighting lamps 2. Multiple lighting lamps 2 are set and 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.

[0023] The lighting lamp 2 is an LED lamp and a ring light. The lighting lamp 2 adopts 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.
