[0029] Example

[0030] Please refer to Figure 1 This embodiment provides a DC charging socket lighting indication control device including a charging socket body 1 and a lighting mechanism installed in the charging socket body 1. The charging socket body 1 is installed on the charging pile and is used to match the charging gun for charging. This embodiment focuses on adding a lighting function so that users can smoothly plug and unplug the charging gun in some surrounding environments or places with dim light and some places without lighting. Specifically, the lighting mechanism includes a lighting lamp, a reed switch, a current limiting resistor and a ring light strip. The lighting lamp is connected in parallel with the reed switch and then in series with the current limiting resistor, and then in series with the power supply to form a loop. The power supply is controlled separately and will not be described in detail here. In order to provide direct and sufficient illumination for the plug-in connection of the charging gun, a base 9 with a positioning hole is connected to one side of the charging socket body 1 by bolts, and the positioning hole of the base 9 matches the plug-in hole of the charging socket body 1, which will not affect the plug-in and pull-out of the charging gun; a circular positioning boss 2 is formed on the side of the base 9 away from the charging socket body 1, and the inner hole of the positioning boss 2 is coaxially distributed with the positioning hole of the base 9, which will also not affect the plug-in and pull-out of the charging gun; an annular gap is formed between the positioning hole of the base 9 and the charging socket body 1, and the annular light strip is embedded in the annular gap, and the lighting lamp of the lighting mechanism is installed in the annular light strip, so that the plug-in and pull-out hole of the charging socket body 1 and the inner hole of the positioning boss 2 can be directly illuminated, so as to facilitate the accurate plug-in and pull-out of the charging gun. By setting the lighting lamp in the annular light strip, the cylindrical light can provide a better field of view to prevent some unexpected situations that occur during the charging process, such as judging whether there are foreign objects in the plug-in port, whether it is damaged, or whether it can be aligned with the corresponding terminal, etc.

[0031] Among them, by connecting the reed switch and the lighting lamp in parallel, the reed switch is used as a normally open switch. When the external magnetic field (the magnetic part on the charging gun) approaches and contacts the reed switch, the reed contact in the reed switch is attracted by the magnetic force and connected, that is, the reed switch is not closed from the normally open state, and forms a loop with the series current limiting resistor, so that the lighting lamp is short-circuited and turned off. When the external magnetic field leaves, the lighting lamp is turned on, wherein the current limiting resistor is used to protect the power supply when the reed switch is closed. By setting the reed switch, an induction switch can be formed with the magnetic part on the charging gun. When the charging gun is inserted into the charging socket body 1, the lighting lamp is turned off, and when the charging gun is away from the charging socket body 1, the lighting lamp is turned on. This control method can better meet the needs of the actual charging state and can greatly reduce power loss.

[0032] In order to obtain a stronger light intensity, there are multiple lamps, and the lamps are LED lamps. The multiple lamps are evenly arranged in a ring shape in the ring light strip. All the lamps are connected in parallel with each other and then in parallel with the reed switch. If one of the lamps is damaged, the other lamps can be used normally. At the same time, multiple lamps arranged in a ring can also enhance the intensity of the tube-shaped light. In addition, there can be multiple reed switches. After all the reed switches are connected in parallel, they are connected in parallel with the overall circuit in which all the lamps are connected in parallel. If one of the reed switches is damaged, the other reed switches can be used normally. The corresponding circuit design only needs to meet the above-mentioned parallel requirements, and there is no restriction on the parallel wiring method.

[0033] In view of the situation that the charging gun is separated from the charging socket body 1 for a long time, or the lighting indication control device is applied to the charging port of an electric vehicle, it is necessary to provide a certain dust protection for the plug-in port of the charging socket body 1. Both sides of the outer ring wall of the positioning boss 2 are processed with mounting grooves 3, and the mounting groove 3 is a U-shaped groove, and the opening of the U-shaped groove is away from one side of the inner hole of the positioning boss 2. A dust cover 5 is hinged in one side of the mounting groove 3, and a fastener that can be movably connected to one side of the dust cover 5 is installed in the other side. Among them, a hinged part is provided on one side of the dust cover 5, and the hinged part and the dust cover 5 are connected at a certain angle, and the angle ranges from 80 to 120°. Here it is a vertical connection, and the hinged part of the dust cover 5 is inserted into the mounting groove 3 and realizes a general pin-type hinge with the mounting groove 3 through a turn pin 6. The side of the dust cover 5 away from the hinged part is a buckle part, and a buckle groove matching the fastener is arranged on the buckle part. The side of the dust cover 5 close to the charging socket body 1 is processed with a countersunk hole matching the shape of the positioning boss 2. When the dust cover 5 is closed, the dust cover 5 completely covers the positioning boss 2, and the buckle part of the dust cover 5 and the fastener are buckled with each other. A torsion spring is arranged between the hinge hole of the fastener and the mounting groove 3 to facilitate pressing one end of the fastener to open the fastener.

[0034] Since the outer shell of an electric vehicle has good reflectivity, when the intensity of the cylindrical light is fully irradiated to the charging port of the electric vehicle, strong reflected light will be formed, thereby affecting the judgment of the human eye. In order to overcome this problem, improvements can be made in terms of light control. However, in order to save electricity and control costs, in this embodiment, a reflective adjustment mechanism is provided on the end face of the positioning boss 2 away from the charging socket body 1. The reflective adjustment mechanism is mainly composed of a plurality of plates, which can partially block the inner hole of the positioning boss 2 under manual or automatic control, thereby reducing the intensity or area of ​​the cylindrical light emitted from the positioning boss 2. Please refer to Figure 2 In this embodiment, the reflective adjustment mechanism includes multiple groups of sunshade assemblies arranged in rotational symmetry. The number of sunshade assemblies is preferably an even number, which can be 4, 6, 8 or 10 groups. However, in order to better fit or match the shape of the outer end surface of the positioning boss 2, in this embodiment, the number of sunshade assemblies is 8. The sunshade assembly includes a sunshade 71 and a positioning head 72. The positioning boss 2 is processed with 8 annularly arranged sockets 7 on the end surface of the side away from the charging socket body 1. The positioning head 72 in each group of sunshade assemblies is correspondingly plugged into a single socket 7. The plug-in method is screwed here, which means that the positioning head 72 is screwed to the socket 7. The shading plate 71 is a curved strip plate, which is bent toward the side away from the inner hole of the positioning boss 2, and the thickness of the shading plate 71 is not more than 5 mm. The width of the shading plate 71 is roughly equal to the difference between the inner and outer diameters of the positioning boss 2, so that the overall rotationally symmetrical pattern of the combination of the eight shading plates 71 can match the outer end surface shape of the positioning boss 2. The shading plates 71 in each group of shading plate assemblies are coated with reflective material on one side close to the charging socket body 1, which can reflect the tubular light to achieve the purpose of reducing the intensity of the tubular light.

[0035] One end of the shading plate 71 is hinged with the positioning head 72 by a hole, and the other end of the shading plate 71 is used to flexibly shield the edge of the inner hole of the positioning boss 2. A fixed head 73 is provided on the outer wall of the inner hole of the positioning boss 2 at one end of the shading plate 71 hinged with the positioning head 72. A traction rope 74 is fixed between the fixed heads 73 of adjacent shading plate assemblies. The traction rope 74 is in a straight state. By pulling one of the traction ropes 74, all the shading plates 71 can be pulled to rotate all the shading plates 71 simultaneously and in the same direction, thereby achieving the purpose of sealing or opening the inner hole of the positioning boss 2. In this embodiment, pulling the traction rope 74 clockwise can make all the shading plates 71 rotate clockwise around their positioning heads 72, thereby partially sealing the inner hole of the positioning boss 2 to achieve the purpose of reducing the intensity of the tube-shaped light, and opening the positioning boss 2 can be operated counterclockwise. One of the traction ropes 74 is used as the driving traction rope 33 , and the driving traction rope 33 is preferably one close to the hinged portion 4 . All the sunshades 71 can be controlled to rotate synchronously by simply pulling the driving traction rope 33 .

[0036] In order to facilitate the operation of the driving traction rope 33, the two ends of the rotating pin 6 are rotatably passed through the two sides of the installation groove 3 through bearings and connected to the driving member. The middle part of the driving traction rope 33 is cut off, and the two rope ends of the driving traction rope 33 after being cut off are respectively connected to the two driving members. By rotating the dust cover 5, the rotating pin 6 drives the two driving members to act synchronously, so that one of the two rope ends in the middle of the driving traction rope 33 is extended and the other is retracted. The driving member can play a simple connecting role, and it is only necessary to meet the requirement that when the driving member rotates, one of the two rope ends in the middle of the driving traction rope 33 is extended and the other is retracted. Specifically in this embodiment, in order to make the dust cover 5 have a vacuum period or blank period between the linkage action of the entire reflective adjustment mechanism, the dust cover 5 can be smoothly opened to 90° before it can play the role of adjusting the reflective adjustment mechanism. The driving member includes a driving wheel 31 and a driven wheel 32. The center of one side end face of the driving wheel 31 is fixedly connected to the end of the rotating pin 6 passing through the mounting groove 3, and the outer ring wall of the driving wheel 31 is processed with a part of the main teeth. Processing with a part of the main teeth means that the part is processed with continuous teeth. The driven wheel 32 is rotatably mounted on the side wall of the mounting groove 3, and the outer ring wall of the driven wheel 32 is processed with a circle of driven teeth that can mesh with the main teeth on the driving wheel. This structural form can make the driven wheel 32 have a vacuum period before meshing with the driving wheel 31, so that all the visors 71 can be adjusted by continuing to rotate the dust cover 5 after the dust cover 5 is opened. The driven wheel 32 is provided with an eccentric pin 34 on the end face away from the mounting groove 3. The projection line of the connection line between the two eccentric pins 34 on any driven wheel 32 always passes through the center of the end face of the driven wheel 32. The two ends of the driving traction rope 33 after being cut are respectively connected to the two eccentric pins 34, so that the purpose of extending one end of the driving traction rope 33 and retracting the other end can be achieved. Figure 4 When the dust cover 5 closes the inner hole of the positioning boss 2, the main tooth is located on the side of the driving wheel 31 away from the driven wheel 32. The dust cover 5 is opened and rotated 120°. At this time, the main tooth begins to mesh with the driven tooth, that is, the state in which all the visors 71 can be adjusted is reached. By continuously rotating the dust cover 5, the two driven wheels 32 can be rotated, and the two eccentric pins 34 begin to change positions. The lower eccentric pin 34 pulls the lower rope head of the driving traction rope 33, and the upper eccentric pin 34 is pulled by the upper rope head of the driving traction rope 33, thereby achieving the purpose of one extending and the other contracting, and finally all the visors 71 begin to cover the edge of the inner hole of the positioning boss 2.

[0037] Due to the shape of the charging gun, in this embodiment, the cross-sectional shape of the inner hole of the positioning boss 2 is not a standard circle, but a shape in which one side of the circle is cut flat. The purpose of cutting flat here is to adapt to the shape of the charging gun on the one hand, and to indicate the plugging and unplugging of the charging gun on the other hand, so that the charging gun can be plugged and unplugged quickly and accurately with positioning. Figure 3An indicating groove 8 is provided on the end face of the positioning boss 2 away from the charging socket body 1. The indicating groove 8 is located on the end face of the positioning boss 2 at the midline of the "cut side". The indicating groove 8 is radially distributed along the inner hole of the positioning boss 2. One side of the indicating groove 8 passes through the inner hole wall of the positioning boss 2, and the indicating groove 8 is provided with a slidable indicating rod 82. The length of the indicating rod 82 is substantially equal to the length of the indicating groove 8. One end of the indicating rod 82 close to the inner hole of the positioning boss 2 is coated with a reflective material 84. One end of the indicating rod 82 away from the inner hole of the positioning boss 2 is formed with a convex head 81, and a pull rope 83 is fixed between the convex head 81 and the visor 71 close to it. When the shading plate 71 is in the starting state, that is, all the shading plates 71 are in the state of not sealing the inner hole of the positioning boss 2, at this time, the indicator rod 82 is just located in the indicator groove 8, and the lower end of the indicator rod 82 does not extend out of the indicator groove 8. When the shading plate 71 is in the sealed state, the indicator rod 82 moves downward, and the reflective material 84 can be quickly and accurately positioned under the human eye, so that the charging gun can quickly find the positioning position. After the charging gun is inserted, the indicator rod 82 can be forced to move up and completely embedded in the indicator groove 8. At this time, all the shading plates 71 return to the starting state. It should be noted that the shading plate 71 in the starting state can form a seal between the charging gun and the positioning boss 2 due to its thin thickness.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
