Description

Technical Field

[0001] This invention belongs to the field of electric vehicle charging technology, and particularly relates to a vehicle charging port adapter. Background Technology

[0002] With my country's economic development and continuous social progress, vehicles have become an indispensable means of transportation for modern people. Furthermore, due to the future trends of low-carbon and intelligent vehicles, the popularity of electric vehicles will continue to grow. Along with continuous technological development and progress, fast charging technology will become increasingly mature. At the same time, with the maturity of technologies such as autonomous driving, manually getting out of the car to charge and manually plugging and unplugging the charging gun is clearly no longer in line with social development trends, necessitating an unmanned, automated charging mode.

[0003] The national standard DC charging port is a standard charging interface used for conductive charging of new energy vehicles. Whether it is a traditional manually plugged-in charging gun or an intelligent charging robot, when it is necessary to charge the vehicle, the charging gun needs to be connected to the national standard charging port on the vehicle body by a person or by an automatic machine to realize the charging of the vehicle.

[0004] Existing national standard DC charging ports generally adopt a multi-pin hole configuration, which requires a high insertion and removal force when manually plugging in the charging port or when the machine automatically plugs in the charging port, making plugging and removing inconvenient. In addition, the relative positional accuracy between each connection hole is required to be high, resulting in high production costs. Summary of the Invention

[0005] To address the shortcomings of the existing technology, this invention provides a vehicle charging port adapter that converts the positive and negative connection holes of the vehicle's standard DC charging port into rotating surfaces, increasing the contact area and reducing the positional accuracy of the connection between the charging gun and the adapter. This reduces production costs, decreases insertion and removal force, and uses a magnetic connection method for convenient positioning and good stability.

[0006] In order to achieve the objective of this invention, the following solution is proposed:

[0007] A vehicle charging port adapter includes:

[0008] The outer casing has a recessed cavity at the front, a cover plate on the top surface of the cavity, and multiple receiving holes at the rear.

When the positioning module is used for car charging, each module on the adapter automatically connects to the corresponding module at the output end of the charging pile.

[0013] Furthermore, the communication module includes a first circuit board, a second circuit board, signal pins, and signal contacts.

One end of the auxiliary power pin is connected to the other side of the second circuit board, and the other end of the auxiliary power pin is connected to the auxiliary power receiving end of the car charging port. One side of the auxiliary power contact is connected to one side of the second circuit board through a conductive rod, and the other side of the auxiliary power contact is inserted into the first circuit board. One end of the positioning module is connected to the side of the second circuit board and is provided with a grounding pin. One end of the grounding pin is connected to the grounding end of the car charging port. The signal pin, the auxiliary power pin, and the grounding pin are all located in the corresponding receiving holes at the rear of the housing.

[0015] Furthermore, the positioning module includes a sleeve base, and a magnet is provided inside the sleeve base.

[0016] Furthermore, the inner wall of the sleeve seat is provided with an arc-shaped concave surface, and a spherical seat is provided outside the magnet. The spherical seat and the arc-shaped concave surface are rotatably engaged. A through hole is provided in the center of the spherical seat, and the magnet is placed in the through hole.

[0017] Furthermore, the inner wall of the sleeve seat is provided with annular floating grooves at both ends, and the spherical seat is provided with limiting rings at both ends. The limiting rings protrude outward and cooperate with the floating grooves.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention will be described in detail below with reference to the accompanying drawings. However, the embodiments described in this invention are only some embodiments of the present invention, and not all embodiments.

[0033] like Figure 1 As shown, this embodiment provides a vehicle charging port adapter. In application, the device is installed on the vehicle's national standard DC charging port. The vehicle charging port adapter includes: a housing 100, a current guide 200, a communication conduction module 300, a low-voltage auxiliary power conduction module 400, and a positioning module 500.

[0034] Specifically, such as Figures 1-2 As shown, the front of the outer casing 100 is recessed and has a receiving cavity. The top surface of the receiving cavity is provided with a cover plate and multiple clearance holes are provided on the cover plate. The rear of the outer casing 100 is provided with multiple receiving holes, which are connected to the receiving cavity.

[0035] Specifically, such as Figure 1 As shown, the flow guide seat 200 is disposed in the accommodating cavity. The flow guide seat 200 includes an inner ring seat 210 and an outer ring seat 220. The inner ring seat 210 is concentrically disposed within the outer ring seat 220. One end of the inner ring seat 210 is provided with a first charging pin 211, and one end of the outer ring seat 220 is provided with a second charging pin 221. One end of the first charging pin 211 is connected to the positive terminal of the vehicle charging port, and one end of the second charging pin 221 is connected to the negative terminal of the vehicle charging port. This allows the connection holes of the positive and negative terminals of the vehicle's national standard DC charging port to be converted into rotating surfaces, increasing the contact area, reducing the positional accuracy of the connection between the charging gun and the adapter, lowering production costs, and reducing the insertion and removal force.

[0036] Specifically, the communication module 300 is located between the inner ring seat 210 and the outer ring seat 220. One end of the communication module 300 is connected to the communication module end of the vehicle charging port, and the other end corresponds to the predetermined position of the clearance hole on the cover plate. When used for vehicle charging, confirm that the connection between the charging gun and the charging end is in place.

[0037] Specifically, the low-voltage auxiliary power supply module 400 is installed inside the communication connection module 300. One end of the low-voltage auxiliary power supply module 400 is connected to the auxiliary power receiving end of the vehicle charging port, and the other end passes through the corresponding clearance hole and is coplanar with the current guide seat 200. The low-voltage auxiliary power supply module 400 is used to supply power to the low-voltage components of the vehicle when the vehicle battery is completely depleted, so as to ensure that the vehicle-related systems can work normally during charging.

[0038] Specifically, the positioning module 500 is located inside the inner ring seat 210 and is concentric with the inner ring seat 210. When the vehicle is charging, the positioning module 500 connects the other end of the inner ring seat 210 to the positive terminal of the charging gun output, and the other end of the outer ring seat 220 connects to the negative terminal of the charging gun output.

[0039] When the vehicle is charging, the other end of the inner ring seat 210 and the outer ring seat 220 is connected to the output end of the charging gun with the ring connector. The other end of the communication connection module 300 is connected to the communication end of the charging gun output end to confirm whether the connection between the charging gun and the charging port is in place. The low-voltage auxiliary power supply connection module 400 is connected to the auxiliary power supply end of the charging gun output end to wake up the vehicle's electronic control system. The other end of the positioning module 500 is connected to the grounding wire of the charging gun output end to realize the charging of the vehicle.

[0040] Specifically, such as Figures 1-3 As shown, the communication module 300 includes a first circuit board, a second circuit board, a signal pin 310, and a signal contact 320. The first circuit board is located at one end of the inner ring seat 210, and the second circuit board is located at the other end of the inner ring seat 210. The first circuit board is situated between the inner ring seat 210 and the outer ring seat 220, while the second circuit board is located within the outer ring seat 220. The signal contact 320 is located on one side of the first circuit board, and the other side of the first circuit board is connected to one side of the second circuit board via a connecting terminal. The other side of the second circuit board has the signal pin 310, one end of which is connected to the communication module end of the vehicle charging interface. When the vehicle is charging, the signal contact 320 connects to the communication module end of the charging gun output, thereby achieving communication with the communication module end of the vehicle charging port to transmit a power-on signal.

[0041] Specifically, such as Figure 2 , Figure 4As shown, the low-voltage auxiliary power supply module 400 includes an auxiliary power pin 410 and an auxiliary power contact 421. One end of the auxiliary power pin 410 is connected to the other side of the second circuit board, and the other end of the auxiliary power pin 410 is connected to the auxiliary power receiving end of the vehicle charging port. One side of the auxiliary power contact 421 is connected to one side of the second circuit board through a conductive rod, and the other side of the auxiliary power contact 421 is disposed on the first circuit board.

[0042] One end of the positioning module 500 is connected to one side of the second circuit board and is provided with a grounding pin 550. One end of the grounding pin 550 is connected to the grounding terminal of the vehicle charging port. The first charging pin 211, the second charging pin 221, the signal pin 310, the auxiliary power pin 410, and the grounding pin 550 are all located in the corresponding receiving holes at the rear of the housing 100.

[0043] Specifically, the positioning module 500 also includes a sleeve base 510, which contains a magnet 530. One end of the magnet 530 is connected to the other end of the grounding pin 550 through the second circuit board, converting the grounding of the charging gun and the adapter into a magnetic connection. This not only enables the connection to be made conductive, but also makes the connection between the charging gun and the adapter stable.

[0044] Specifically, such as Figure 5 As shown, the inner wall of the sleeve seat 510 is provided with an arc-shaped concave surface, and a spherical seat 520 is provided outside the magnet 530. The spherical seat 520 is rotatably engaged with the arc-shaped concave surface. The center of the spherical seat 520 is provided with a through hole, and the magnet 530 is located in the through hole. One end of the magnet 530 extends out of the spherical seat 520 and protrudes from one end of the sleeve seat 510. When there is an error in the connection between the charging gun and the adapter, the magnet 530 can drive the spherical seat 520 to swing at a small angle in any direction within the sleeve seat 510 to adapt to the connection between the charging gun and the adapter.

[0045] Specifically, the inner walls of the sleeve seat 510 are provided with annular floating grooves 511 at both ends. The floating grooves 511 are horizontally V-shaped with their openings facing the axis of the sleeve seat 510. The sides of the floating grooves 511 are perpendicular to each other, and their angle bisectors are parallel to the radial direction of the sleeve seat 510. The spherical seat 520 is provided with limiting rings 521 at both ends. The limiting rings 521 protrude outward and cooperate with the floating grooves 511. The limiting rings 521 include a first inclined surface and a second inclined surface. The lower end of the first inclined surface is connected to the upper end of the second inclined surface. The upper end of the first inclined surface is inclined inward and the lower end is inclined outward. The upper end of the second inclined surface is inclined outward and the lower end is inclined inward. The first inclined surface is parallel to one side of the floating groove 511, and the second inclined surface is parallel to the other side of the floating groove 511. When the spherical seat 520 swings inside the sleeve seat 510, the floating grooves 511 and the limiting rings 521 can limit the spherical seat 420.

[0046] Specifically, such as Figures 4-5 As shown, one end of the magnet 530 is provided with an elastic part 540. The elastic part 540 includes a column 541. One end of the column 541 is provided with an elastic element 542. The other end of the elastic element 542 abuts against the second circuit board to increase the connection stability between the charging gun and the adapter. One side of the column 541 is provided with a protruding edge 543. The protruding edge 543 cooperates with the limiting ring 521 to limit the distance of the elastic element 542.

[0047] Specifically, one side of the column 541 is recessed inward and has a groove 5411. One end of the elastic member 542 is located in the groove 5411 and is connected to the bottom of the groove 5411.

[0048] Specifically, in order to increase the stability of the connection between the adapter and the vehicle charging port, the outer wall of the housing 100 is provided with a locking member 110, which is used to connect with the housing of the vehicle charging port.

[0049] The above description is merely a preferred embodiment of the present invention and is not intended to be the only or limiting of the invention.
