Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle charging equipment technology, specifically to a virtual charging gun. Background Technology

[0002] New energy vehicles refer to all vehicles powered by energy sources other than gasoline and diesel engines. They are believed to reduce air pollution and alleviate energy shortages, representing an upgrade from traditional vehicles. Given the current global emphasis on environmental protection, the new energy vehicle industry will inevitably become the guiding principle and goal for the future development of the automotive industry. However, the development of new energy vehicles is inseparable from power supply technology, and charging is one of the most crucial technologies.

[0003] In 2024, my country's new energy vehicle sales reached 11 million units, but the increase in charging piles lagged far behind, with a charging pile-to-vehicle ratio of only 1:4. If private and public charging piles are excluded, the actual vehicle-to-charging-pile ratio is as high as 7:1, far below the ideal 1:1. Especially in older residential areas, remote areas, and urban core areas, charging pile coverage is extremely low, and car owners often have to spend a lot of time searching for available charging piles. Moreover, about 40% of electric vehicle owners cannot install private charging piles due to issues such as lack of fixed parking spaces, property restrictions, or high grid expansion costs. Door-to-door charging, using mobile energy storage devices to bypass infrastructure restrictions and directly replenish energy for car owners, has become the only feasible solution. However, existing door-to-door charging services for new energy vehicles have the following drawbacks:

[0004] 1. Automatic closing of charging port: The charging port of new energy vehicles requires the owner to authorize it through the APP to open. However, Tesla and other models will automatically close the charging port within 30 seconds when no real charging gun is detected (according to Tesla 2023 user manual). This requires a high level of skill from the owner and the charging personnel. In actual operation, the charging port will often be automatically closed when the mobile charging vehicle arrives, making it impossible to charge directly.

[0005] 2. Repeated manual authorization: Before charging, the user needs to remotely unlock the charging port, which takes an average of 5-8 minutes; after charging, a second authorization is required to unplug the gun, and the failure rate of this operation is about 12%. Utility Model Content

[0006] To address this issue, this utility model provides a virtual charging gun to solve the problems of automatic locking of vehicle charging ports and repeated authorization in door-to-door mobile charging services.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A virtual charging gun includes a gun body, one end of which is provided with a contoured gun head. A through groove is provided on the contoured gun head at a position corresponding to the locking component inside the car charging port. The side of the contoured gun head that is inserted into the car charging port is provided with a first contact and a second contact. When the contoured gun head is inserted into the car charging port, the first contact is connected to the CC2 terminal inside the car charging port, and the second contact is connected to the PE terminal inside the car charging port. A resistor is provided between the first contact and the second contact.

[0009] Furthermore, the through groove is provided on the surrounding sidewalls of the contour gun head.

[0010] Furthermore, the depth of the through groove is not less than 16mm.

[0011] Furthermore, the resistance value of the resistor is not less than 1kΩ.

[0012] Furthermore, the gun body is equipped with a padlock, one end of which has a hook that hooks into the slot of the car charging port; the other end of the padlock is a pressing end that is exposed on the surface of the gun body; the middle of the padlock is rotatably connected to the gun body, and a return spring is provided between the padlock and the gun body, the return spring being located between the rotation center of the padlock and the pressing end.

[0013] Furthermore, the padlock has a protrusion in the middle, the protrusion has a through hole, and the gun body has a shaft that passes through the through hole.

[0014] The present invention has the following advantages:

[0015] This invention relates to a virtual charging gun that uses a precise contouring structure to physically deceive the vehicle detection system. It can trigger a micro switch on the charging port to simulate the insertion state of a real charging gun. It uses a standard signal to keep the charging port open, allowing the charging vehicle to autonomously complete the plugging and unplugging operation. This eliminates the need for manual interaction and saves two manual authorization steps (each saving 5-8 minutes). Moreover, the plugging and unplugging operation time is reduced from the industry average of 45 seconds to 3 seconds.

[0016] This utility model discloses a virtual charging gun that can achieve adaptive compatibility with multiple vehicle models, namely, it supports the charging port specifications and communication protocols of mainstream models such as Tesla and NIO, covering 92% of the models on the market, and the adjustable resistance value range covers the GB / T20234-2015 standard.

[0017] This utility model discloses a virtual charging gun with an anti-detachment design buckle to ensure the stability of the gun body. The anti-detachment buckle, together with the positioning pin, achieves a ±0.3mm alignment accuracy and an anti-accidental unlocking structure, making charging safe and reliable.

[0026] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] like Figure 1-3As shown, a virtual charging gun includes a gun body 1, which is used by the operator to hold and support other structures. One end of the gun body 1 is provided with a contoured gun head 2, the shape of which matches the shape of the car charging port. When in use, the contoured gun head 2 will be inserted into the car charging port.

[0028] The contoured gun head 2 has a through groove 3 at a position corresponding to the locking mechanism inside the car charging port. The through groove 3 extends from a certain position on the side where the contoured gun head 2 connects to the gun body 1 to the outer end of the contoured gun head 2. This position on the side where the contoured gun head 2 connects to the gun body 1 is determined by the position of the mechanical lock's latch on the contoured gun head 2 after it is inserted into the car charging port, ensuring that the lock head enters the through groove 3 when the latch is engaged. When the car owner unlocks the car using the key / APP, opens the charging port, and inserts the contoured gun head 2 into the vehicle's charging port, a soft "click" sound is heard, indicating that the mechanical lock is initially engaged. Because the locking groove on the contoured gun head 2 is a through groove 3 (i.e., an unobstructed structure), the mechanical lock of the car charging port is engaged, but the contoured gun head 2 can be pulled out of the car charging port, and the mechanical lock of the car charging port cannot lock the virtual charging gun of this technology. Since the mechanical locks inside the car charging port are all located on their surrounding inner walls, in this technology, the through groove 3 is located on the surrounding side walls of the contour gun head 2. In this technology, the depth of the through groove 3 is not less than 16mm.

[0029] The contoured charging head 2 has a first contact 4 and a second contact 5 on the side that inserts into the car charging port. When the contoured charging head 2 is inserted into the car charging port, the first contact 4 connects to the CC2 terminal inside the car charging port, and the second contact 5 connects to the PE terminal inside the car charging port. A resistor 6 is provided between the first contact 4 and the second contact 5. The resistance of the resistor 6 is not less than 1kΩ. When the contoured charging head 2 is inserted into the car charging port, the first contact 4 connects to the CC2 terminal, and the second contact 5 connects to the PE terminal. This changes the total resistance 6 between the CC2 terminal and the PE terminal in the circuit of the car charging port, thereby changing the voltage. This causes the car charging port to mistakenly believe that a matching charging gun has been inserted, thus maintaining the open signal.

[0030] like Figure 4As shown, the gun body 1 is equipped with a padlock 7. One end of the padlock 7 has a hook 8, which hooks onto the slot of the end seat at the car charging port. The other end of the padlock 7 is a pressing end 9, which is exposed on the surface of the gun body 1. The middle of the padlock 7 is rotatably connected to the gun body 1. A return spring 13 is provided between the padlock 7 and the gun body 1. The return spring 13 is located between the rotation center of the padlock 7 and the pressing end 9. When the contour gun head 2 is inserted into the car charging port, the hook 8 hooks onto the slot of the end seat at the car charging port, and the return spring 13 provides the rotational force for the hook 8 to hook. When it is necessary to pull out the contour gun head 2, the user presses the outer end of the padlock 7, and the padlock 7 rotates around its middle as the rotation center. At the same time, the return spring 13 is squeezed, and the hook 8 will disengage from the slot of the end seat due to the rotation of the padlock 7, thus achieving manual unlocking. The padlock 7 has a protrusion 10 in the middle, and a through hole 11 on the protrusion 10. The gun body 1 has a shaft 12 that passes through the through hole 11. The return spring 13 is located between the protrusion 10 and the pressing end 9, so that the return spring 13 provides an outward lifting force to the pressing end 9 of the padlock 7, so that the locking hook 8 of the padlock 7 has an inward pressing force, that is, the pressing force of the locking hook 8 hooking the groove of the car end seat.

[0031] When this virtual charging gun is used in practice:

[0032] When a user places an order, they authorize the opening of their car charging port. Then, the virtual gun head is inserted into the car charging port. The protruding gun head 2 contacts the sensor inside the car charging port, and the first contact 4 is connected to the CC2 terminal and the second contact 5 is connected to the PE terminal, thereby triggering the car charging port to remain open signal.

[0033] Then, after the charging personnel arrive, press the pressing end 9 of the padlock 7 to unlock the locking hook 8 of the padlock 7, and replace the virtual charging gun with the real charging gun. This process does not require the car owner to authorize again. After the charging personnel scan the code of the charging vehicle, they activate the cloud authorization and start the charging process.

[0034] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
