Description

Technical Field

[0001] This utility model relates to the field of vehicle socket technology, specifically to a high-power intelligent switching box. Background Technology

[0002] Car sockets (including USB ports, 12V power supplies, etc.) are mainly used for charging electronic devices (such as mobile phones and tablets), supporting data transfer (such as playing music from a USB flash drive), and supplying power to in-vehicle appliances (such as vacuum cleaners and refrigerators). With the development of new energy vehicles, there are more and more in-vehicle electrical devices, and the conventional USB ports used for charging mobile phones can no longer meet the needs of all users. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the shortcomings of existing technology where there are more and more vehicle-mounted electrical devices and conventional interfaces cannot meet the requirements, thereby providing a high-power intelligent switching box that can support interface charging and discharging.

[0004] Therefore, this utility model provides a high-power intelligent switching box, including a socket and a control box connected to the socket. The control box is provided with a first port for charging and a second port for charging or discharging. The first port and the second port are connected together. A relay is connected to the second port. The second port is connected to the socket. The second port controls the socket to be powered through the relay.

[0005] Furthermore: the relay includes a first relay and a second relay connected to the second port, the control box includes a bottom cover and a protective shell covering the bottom cover, the first relay and the second relay are both embedded between the bottom cover and the protective shell, and the protective shell has a first clearance groove and a second clearance groove for avoiding the first port and the second port.

[0006] Furthermore: both the first port and the second port are disposed on the connecting plate, and the connecting plate abuts against the outer end face of the protective shell.

[0007] Furthermore: the socket and the control box are connected by a wire harness, the control box contains a PCB chip, a conductive spring is soldered onto the PCB chip, and a safety cover is embedded above the conductive spring to prevent accidental contact.

[0008] Furthermore: the socket includes a base, a panel covering the base, and a safety door cover between the base and the panel, the conductive spring is embedded between the base and the safety door cover, and the safety cover is located above the safety door cover and covers the upper end of the conductive spring.

[0009] Furthermore, a protective cover is provided on the top of the panel.

[0010] The technical solution of this utility model has the following advantages: 1. This utility model provides a high-power intelligent switching box, which has charging and discharging states. A first port and a second port are connected. During charging, the charging gun is inserted through the first port, and then the battery is charged via the input to the vehicle's OBC (On-Board Charger) through the second port (at this time, the socket is in a de-energized state under the action of a relay to ensure charging safety). When it is necessary to supply power from the vehicle to an external source (e.g., when a tablet or other electrical appliance needs to be charged using a lead-out socket), the vehicle's infotainment system inputs a signal through the control port, and the OBC discharges through the socket connected to the second port via the vehicle's internal socket. When a device compatible with the first port is connected, the power collection gun can also be directly connected to the outer port of the first port. The vehicle's infotainment system inputs a signal through the control port, allowing the electrical energy in the vehicle's battery to be released or supplied to the external device. In this way, when we are camping or using lighting in the wild, we can power external devices through the car to meet the needs of high-power outdoor electrical equipment.

[0011] 2. The present invention provides a high-power intelligent switching box, the control box including a bottom cover and a protective shell covering the bottom cover, which fixes the first relay, the second relay, the first port and the second port between the bottom cover and the protective shell, effectively accommodating and protecting the components, and achieving the effect of dustproof and waterproof.

[0018] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0019] Example This embodiment provides a high-power intelligent switching box, including a socket 1 and a control box 2 connected to the socket 1. The control box 2 is provided with a first port 3 for charging and a second port 4 for charging or discharging. The first port 3 and the second port 4 are connected together. A relay is connected to the second port 4. The second port 4 is connected to the socket. The second port 4 controls the socket 1 to be powered through the relay.

[0020] The specific improvements are as follows: The intelligent switching box has charging and discharging states. The first port 3 and the second port 4 are connected. When charging, the charging gun is inserted from the first port 3 and then input to the vehicle's OBC to charge the battery through the second port 4 (at this time, the socket 1 is in a power-off state under the action of the relay to ensure charging safety). When it is necessary to supply the vehicle's power to the outside (for example, when it is necessary to use the lead-out socket 1 to charge a tablet or other electrical appliances), the vehicle's system inputs a signal through the control port 10, and the OBC discharges through the socket 1 connected to the second port 4. When a device that is compatible with the first port 3 is connected, the charging gun can also be directly connected to the outer port of the first port 3. The vehicle's system inputs a signal through the control port 10 to allow the electrical energy in the vehicle battery to be released or supplied to external devices. In this way, when we are camping or lighting in the wild, we can supply power to external devices through the car. In this embodiment, the first port 3 is a charging port, and the second port 4 is a port that can be used for both charging and discharging.

[0021] Based on the above embodiments: such as Figures 1-3 As shown, the relay includes a first relay 31 and a second relay 41 connected to the second port 4. The control box 2 includes a bottom cover 21 and a protective shell 22 covering the bottom cover 21. The first relay 31 and the second relay 41 are both embedded between the bottom cover 21 and the protective shell 22. The protective shell 22 has a first clearance groove 5 and a second clearance groove 6 that avoids the first port 3 and the second port 4.

[0022] like Figure 2 As shown, the relays include a first relay 31 and a second relay 41 that control the neutral wire and the live wire. The control box 2 receives control signals from the EDS2. These signals may include commands such as start, stop, and mode switching. These signals are used to automatically switch the states of the first relay 31 and the second relay 41, thereby realizing the control of charging or discharging operations. Based on the above embodiments: both the first port 3 and the second port 4 are disposed on the connecting plate 7, and the connecting plate 7 abuts against the outer end face of the protective shell 22.

[0023] The specific improvements mentioned above are as follows: Figure 2As shown, the control box 2 includes a bottom cover 21 and a protective shell 22 covering the bottom cover 21. The first relay 31, the second relay 41, the first port 3, and the second port 4 are fixed between the bottom cover 21 and the protective shell 22, which can effectively accommodate and protect the components, and provide dust and water protection. The first port 3 and the second port 4 are both fixed on the connecting plate 7, which is embedded in the first clearance groove 5, so as to facilitate the insertion of external interfaces. The control box 2 is fixed in the second clearance groove 6. The control box 2 receives control signals from the EDS2. These signals may include commands such as start, stop, and mode switching. These signals are used to automatically switch the state of the first relay 31 and the second relay 41, thereby realizing the control of charging and discharging operations. The control box 2 acts as a key component of the new energy vehicle charging system. According to the user's needs, it manages the charging and discharging operations by switching the high-voltage AC connection to ensure the safety and effectiveness of energy management. At the same time, by receiving signals from the EDS2, it makes the entire system more intelligent and controllable.

[0024] Based on the above embodiments: the socket 1 and the control box 2 are connected by a wire harness 11. The control box 2 is provided with a PCB chip 23. A conductive spring 24 is soldered on the PCB chip 23. A safety cover 8 for preventing accidental contact is embedded above the conductive spring 24.

[0025] The specific improvements mentioned above are as follows: the socket 1 and the control box 2 are connected by a wiring harness 11. The wiring harness 11 can use a longer wire, so that when power is needed, the socket 1 can be extended to the trunk for power supply. The socket 1 is a high-power power socket 1, which is directly connected to the controller to meet the needs of outdoor high-power electrical equipment, up to 3.3KW. The safety cover 8 can effectively cover the spring and prevent children from accidentally touching it with their fingers.

[0026] Based on the above embodiments: the conductive spring 24 is embedded between the base and the safety door cover plate, and the safety cover 8 is located above the safety door cover plate and covers the upper end of the conductive spring 24.

[0027] Based on the above embodiment: a protective cover 9 is provided on the top of the panel 102.

[0028] The specific improvements mentioned above are as follows: by setting the base and safety door cover 103, the conductive spring 24 and the safety cover 8 above the conductive spring 24 can be effectively fixed. By setting the cover 9, the cover 9 covers the panel 102 to prevent impurities, moisture and other substances from entering the control box 2 from the panel 102, thereby causing the entire control box 2 to fail.

[0029] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
