Description

Technical Field

[0001] The utility model relates to the technical field of charging equipment, and in particular to an oil-cooled charging gun and a charging equipment. Background Art

[0002] In the current electric vehicle charging technology, the oil-cooled charging gun is a common charging device, which cools the charging gun and battery through oil circulation to keep the temperature stable during the charging process. At present, in order to match the domestic charging port, the oil-cooled charging gun needs to be designed as a single oil inlet and single oil outlet structure, but this design has some obvious limitations and challenges in practical applications.

[0003] First, the design of single oil inlet and single oil outlet may lead to limitations in oil flow during charging. The oil needs to flow from the oil inlet into the charging gun and then flow out through the oil outlet to complete the cooling cycle. However, since there is only one oil inlet and one oil outlet, the flow of oil may be restricted, resulting in poor cooling effect, which in turn affects charging efficiency and safety, especially when the oil port is blocked, the cooling structure completely fails, which also increases the maintenance frequency.

[0004] Secondly, since there is only one oil port for both oil inlet and outlet, the single inlet and single outlet design may cause the oil pressure load to be concentrated on one oil port. In high-voltage charging applications, the oil pressure load may cause a large pressure on the oil port, thus affecting its reliability and durability. This may cause premature damage or leakage of the oil port, increasing maintenance costs and potential safety risks.

[0005] In addition, the above structural design may also limit the application scope of the charging gun, especially since this structure can only fully cool one charging port at a time, making it difficult to adapt to foreign charging standard interfaces, thereby limiting the application scope and adaptability of the charging gun.

[0009] In one embodiment of the present invention, the guide member includes a connecting portion and an introducing portion which are interconnected, the connecting portion is connected to the oil supply pipe, and the introducing portion is inclined toward the first accommodating chamber or the second accommodating chamber.

When the temperature exceeds the set value, the thermistor will send a signal to the control system so that timely measures can be taken to prevent overheating, so that the charging gun can work in a safe environment and avoid safety problems caused by overheating.

[0030] See also Figures 2 to 4As shown, in this embodiment, the diameters of the first accommodating cavity 221 and the second accommodating cavity 222 of the oil pipe housing 220 can be matched with the first connector 211 and the second connector 212 respectively.

The two guide members 2232 are symmetrically arranged. Based on this structural arrangement, the flow rates of the two guide members 2232 during the oil supply cooling process are similar, thereby achieving uniform diversion, thereby balancing the cooling effect, avoiding the pressure load of the oil that may cause a large pressure on the oil port, and extending the service life of the oil supply component 223. Furthermore, the guide member 2232 in this embodiment includes a connecting portion 2233 and an introduction portion 2234 that are interconnected, the connecting portion 2233 is connected to the oil supply pipe 2231, and the introduction portion 2234 is inclined toward the first accommodating chamber 221 or the second accommodating chamber 222.

This process involves the coordinated work of transistors, power amplifiers, modems and other circuits to ensure the efficiency and stability of the charging process. The meson connector is mainly used for data exchange and security authentication. It uses short-range wireless communication technology to transmit authentication information, charging parameters and other data between the charging gun and the charging device to achieve fast pairing, simplify the connection process between the charging gun and the charging device, and also ensure the safety of the charging process.
