Description

Technical Field

[0001] The utility model relates to the technical field of charging piles, in particular to a novel double-gun DC charging pile. Background Art

[0002] Charging piles refer to charging equipment that provides charging services for electric vehicles. Charging piles can be fixed on the ground or on the wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. They can charge various types of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging gun through a cable for charging electric vehicles. Among them, in order to improve the utilization rate of charging piles, a dual-gun charging pile has been widely used.

[0003] For dual-gun charging piles, in order to meet the charging needs of two new energy vehicles at different locations, they generally have longer charging cables. After charging the vehicle, some users generally simply insert the charging gun into the charging gun slot to end the charging process, and do not store the charging cable, so that the charging cable is left on the ground for a long time. The long-term mopping operation of the charging cable is very likely to cause wear and tear, thus affecting the normal use of the charging pile. Utility Model Content

[0026] 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.

[0027] See also Figure 1-7 The utility model provides a technical solution: a new type of double-gun DC charging pile, including a charging pile body 1, a cable 2 connected to the charging pile body 1 at the bottom, and a charging gun 3 connected to the top of the cable 2. The charging gun 3 includes a connecting column 3.1 connected to the cable 2 at the bottom, a box body 3.2 fixed to the top of the connecting column 3.1, and a plug 3.3 fixed to the inner side of the box body 3.2.

[0028] The support and storage assembly 4 includes a base 4.1, a socket 4.2 and a spring member 4.3; the base 4.1 includes a transverse column 4.1.1 whose inner end is fixed to the upper middle side of the side wall of the charging pile body 1 and an end plate 4.1.2 whose inner side wall bottom is fixed to the outer end surface of the transverse column 4.1.1, a vertical groove 4.1.4 extending downward is provided on the top surface of the transverse column 4.1.1, and a slot 4.1.5 is provided on the end plate 4.1.2 corresponding to the bottom of the vertical groove 4.1.4; the socket 4.2 is vertically slidably mounted in the vertical groove 4.1.4, and a slot 4.2.1 is provided in the middle of the outer end surface of the socket 4.2; the spring member 4.3 is vertically connected between the bottom surface of the socket 4.2 and the bottom surface of the inner cavity of the vertical groove 4.1.4. Among them, an arc-shaped plate 4.2.2 whose inner peripheral wall diameter is equal to the outer diameter of the transverse column 4.1.1 is fixed to the top of the socket 4.2. A connecting flange 4.1.3 is fixed to the outer peripheral wall of the inner end of the transverse column 4.1.1, and the connecting flange 4.1.3 is fixedly connected to the side wall of the charging pile body 1 by bolts. The slot 4.2.1 is plugged and matched with the plug 3.3.

[0029] The side wall of the slot 4.2.1 is provided with a proximity sensor 5 whose output end is electrically connected to the input end of the charging settlement control module inside the charging pile body 1. Among them, the socket 4.2 is provided with side cavities 4.2.3 at the front and rear sides of the slot 4.2.1, and the front wall of the slot 4.2.1 is provided with a socket 4.2.4 that matches the rear end sleeve of the proximity sensor 5. The front wall of the socket 4.2 is provided with a threaded hole 4.2.5 at a position corresponding to the socket 4.2.4, and the front peripheral wall of the proximity sensor 5 is provided with an external thread 5.1 that matches the threaded sleeve of the threaded hole 4.2.5. In order to facilitate the disassembly and assembly of the proximity sensor 5, a regular hexagonal groove 5.2 is provided on the front face of the proximity sensor 5. That is, the proximity sensor 5 can be disassembled and installed through the regular hexagonal groove 5.2 by using an inner hexagonal wrench.

[0030] In summary, when the user charges his new energy vehicle, there is no load on the arc plate 4.2.2, and the spring member 4.3 exerts an upward elastic force on the socket 4.2, so that the socket 4.2 slides upward along the vertical slot 4.1.4 for a certain distance, so that the slot 4.2.1 is staggered with the slot hole 4.1.5.

[0031] After the new energy vehicle is charged, the charging gun 3 needs to be reset to complete the charging settlement procedure. At this time, the cable 2 needs to be wrapped around the horizontal column 4.1.1 for several turns. The wrapped cable 2 applies downward pressure to the socket 4.2 as a whole through the arc plate 4.2.2, so that the socket 4.2 compresses the spring member 4.3 and moves downward a certain distance, so that the slot 4.2.1 is just aligned with the slot 4.1.5, so as to facilitate the insertion of the charging gun 3, that is, the box body 3.2 is inserted into the slot 4.1.5, and the plug 3.3 is inserted into the slot 4.2.1. After completing the insertion operation of the charging gun 3, the proximity sensor 5 will transmit the signal detected by the plug 3.3 to the charging settlement control module integrated in the charging pile body 1, so that the charging settlement control module performs the electricity price calculation, settlement and other processes, so as to end the charging procedure.

[0032] Among them, the charging settlement control module inside the charging pile body 1 is an existing technology, which involves scanning codes, swiping cards and other operations to obtain charging permissions, and electricity charges are calculated after charging is completed. After the user completes the payment operation, the charging program ends. The specific structure content is not repeated here. The proximity sensor 5 is equivalent to adding a condition to the given electricity charge calculation program, that is, the electricity charge calculation and settlement payment operations can only be performed after the charging gun 3 is inserted and stored.

[0033] The top and bottom ends of the spring member 4.3 are respectively fixed with circular plates 4.3.1, the middle part of the top circular plate 4.3.1 is rotatably sleeved with a rotating shaft 4.3.2, the top end of the rotating shaft 4.3.2 is fixedly docked with an upper bolt 4.3.3, and the center of the bottom surface of the bottom circular plate 4.3.1 is vertically fixed with a lower bolt 4.3.4, the front and rear sides of the middle part of the bottom surface of the socket 4.2 are provided with screw holes that are threadedly matched with the upper bolt 4.3.3, and the front and rear sides of the middle part of the bottom surface of the vertical slot 4.1.4 are respectively provided with screw holes that are threadedly matched with the lower bolt 4.3.4.
