Technical Field

[0001] The invention relates to the technical field of automobile electrical connection, and in particular to a charging seat and an automobile with a terminal having a cooling system. Background Art

[0002] The charging stand is a common electronic device. When people use the charging stand to charge, they often find that the charging stand heats up. The heating of the charging stand is a phenomenon in which the charging stand converts electrical energy into heat energy during the charging process.

[0003] The heating phenomenon of the charging stand during the charging process not only seriously affects the charging speed, but also easily causes aging of components on the charging stand, seriously affecting the normal use of the charging stand. Summary of the invention

[0004] The purpose of the present invention is to provide a charging stand and a car with terminals having a cooling system, which can take away the heat generated by the charging stand during the charging process and prevent the charging stand from heating up during the charging process and affecting the normal use of the charging stand to a certain extent.

[0009] The portion of the hollow cylindrical terminal located in the insulating liquid tube is provided with a liquid inlet channel connecting the liquid channel and the inner cavity of the hollow cylindrical terminal. By providing the liquid channel, cooling liquid can flow between the insulating liquid tube and the hollow cylindrical terminal and the terminal wire, and the cooling liquid can enter the inner cavity of the hollow cylindrical terminal through the liquid inlet channel, thereby achieving the purpose of cooling the hollow cylindrical terminal.

A seal is formed between the starting end of the insulating liquid tube and the middle section of the hollow cylindrical terminal, which can seal the liquid channel and prevent the liquid in the liquid channel from flowing out.

[0011] Preferably, the insulating liquid tube is coaxially arranged with the hollow cylindrical terminal and the terminal wire, and the liquid passage between the insulating liquid tube, the hollow cylindrical terminal and the terminal wire is annular. Since the inner radial dimension of the insulating liquid tube is larger than the outer radial dimension of the tail section of the hollow cylindrical terminal and the terminal wire, an annular liquid passage is formed between the insulating liquid tube, the hollow cylindrical terminal and the terminal wire.

[0012] Preferably, the hollow cylindrical terminal is a pair of parallel hollow cylindrical terminals, a circulation conduit is provided between the pair of hollow cylindrical terminals, the circulation conduit is respectively connected to the inner cavity of the hollow cylindrical terminal, and the circulation conduit is perpendicular to the pair of hollow cylindrical terminals.

[0014] Preferably, a sealing ring is provided at the end of the circulation conduit, and the sealing ring is installed between the hole wall of the liquid through hole and the end of the circulation conduit. The sealing ring can achieve sealing between the circulation conduit and the hollow cylindrical terminal.

[0015] Preferably, the end of the terminal wire is fixed in the inner cavity of the tail end of the hollow cylindrical terminal. The terminal wire is installed in the inner cavity of the tail end of the hollow cylindrical terminal to prevent the terminal wire from affecting the flow of coolant in the inner cavity of the hollow cylindrical terminal.

[0016] Preferably, it also includes a tail cover and a cable waterproof pad arranged in the tail cover;

[0017] The tail section of the hollow cylindrical terminal passes through the terminal hole of the cable waterproof pad and the terminal hole of the tail cover in sequence; the gap between the insulating liquid tube outside the tail section of the hollow cylindrical terminal and the terminal hole of the tail cover is sealed by the first protrusion along the edge of the terminal hole of the cable waterproof pad. The first protrusion is used to seal the gap between the tail cover and the insulating liquid tube, which can prevent impurities, water vapor, etc. from entering the interior of the charging seat and causing the insulation performance to deteriorate.

[0018] Preferably, it further comprises a terminal pressing plate, which is arranged between the tail cover and the circulation conduit and is used for positioning the hollow cylindrical terminal relative to the tail cover;

[0019] The tail end of the terminal pressing plate presses the cable waterproof pad tightly against the inner wall of the tail cover, and the head end of the terminal pressing plate is connected to the outer wall of the circulation conduit.

[0020] On the other hand, the present invention also provides a car, comprising the above-mentioned charging base.
