Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicles, and in particular to a battery charging port structure for an intelligent electric vehicle. Background Art

[0002] As an energy storage medium for new energy vehicles, lithium batteries are increasingly being used. After the lithium battery's energy is consumed, it needs to be recharged before it can be used. Currently, most lithium batteries are fixed on mobile tools and must be charged in the vehicle. Or some batteries that can be removed from the vehicle for charging require special equipment and environment for charging, which is complicated to operate and poses certain safety risks. Summary of the invention

[0003] In view of the deficiencies in the above-mentioned prior art, the technical problem to be solved by the present invention is how to provide a smart electric vehicle battery charging port structure that can better charge, is convenient and safe to use, has a simple structure, and is waterproof and dustproof.

[0004] To this end, the technical solution of the present invention is: a smart electric vehicle battery charging port structure, including a charging port connector, a charging line is arranged in the charging port connector, and a communication line is also arranged in the charging port connector, and the communication line is connected to the battery charging protection board.

[0005] In this way, a communication line is added, the communication line is connected to the battery charging protection board, and the charging line and the communication line are separately isolated, which can ensure the safety of the circuit and the safety of operation during charging. When charging, the communication signal with low voltage and low current is used for communication first. When it is confirmed that there is no safety risk, the charging circuit with high voltage and high current is used for charging, which ensures the safety of charging. The charging current of the charging port separates the communication circuit with low voltage and low current from the charging circuit with high voltage and high current to ensure the safety of the circuit and the safety of operation during charging.

[0006] Furthermore, the battery surface is concave to form a recess matching the charging port connector, and the charging port connector is fixedly installed in the recess.

[0007] In this way, the charging port connector can be easily installed, and the protrusion of the charging port connector can be better avoided. When in use, it will not interfere with or collide with other structures, and the structure is firm, safe and stable.

[0008] Furthermore, the notch is arranged on an upper portion of a surface of the battery facing the battery mounting bracket.

[0009] In this way, the recess is set at the rear of the battery. When the battery is installed on the battery bracket, the charging port connector is hidden at the rear of the battery, which can better ensure that the user cannot charge the vehicle when using the vehicle. At the same time, it can prevent foreign objects from entering or damaging the charging port connector, which can better extend the service life of the charging port connector.

[0010] Furthermore, the charging port connector includes a rectangular connecting block and a cylinder fixedly installed on one side of the rectangular connecting block, and reinforcing ribs are arranged between the outer side of the cylinder and the rectangular connecting block; the recess includes a rectangular hole and a countersunk hole concave along the surface of the battery, the rectangular hole matches the rectangular connecting block, and the countersunk hole matches the cylinder and the reinforcing ribs on the outer side of the cylinder; a through hole is horizontally penetrated through the rectangular connecting block, and the surface of the cylinder facing the through hole is concave to form a blind hole connected to the through hole, and the connection terminals of the charging cable and the communication cable are fixedly installed at the bottom of the blind hole.

[0011] In this way, the charging port connector is fixedly installed in the recess, and the recess matches the charging port connector structure, so that it can be better installed and fixed.

[0012] Furthermore, a sealing ring is provided between the rectangular connecting block and the bottom of the rectangular hole.

[0013] In this way, the sealing ring is provided to better seal the recess to prevent water and dust.

[0014] Furthermore, the bottom of the blind hole is provided with an asymmetric protrusion fool-proof structure, and the fool-proof structure includes a first protrusion arranged on one side of the charging cable terminal and two second protrusions arranged on the other side of the charging cable terminal.

[0015] In this way, when charging, due to the provision of a fool-proof structure, reverse connection or short circuit can be avoided during charging. The fool-proof structure is an asymmetric protrusion, which can be better distinguished to avoid unexpected situations during charging.

[0016] Furthermore, the first protrusion is L-shaped, one end of the first protrusion is fixedly installed at the bottom of the blind hole, and the other end is arranged outwardly, and the second protrusion has the same structure as the first protrusion.

[0017] In this way, the protrusion is L-shaped, and one end of the protrusion is horizontally arranged outward, so that it can be limited during charging to prevent reverse connection or short circuit from occurring during charging.

[0018] In summary, the present invention has the advantages of being able to charge better, being convenient and safe to use, having a simple structure, and being waterproof and dustproof. BRIEF DESCRIPTION OF THE DRAWINGS
