Example 1

As shown in fig. 1, the charging terminal of the present embodiment includes: a conductive member 1, an insulating moving member 2, a power output member 3, and a driving member 4. Wherein the conductive member 1 is used for transmitting electric energy; the insulating moving member 2 is slidably mounted on the conductive member 1; the power output part 3 is arranged on the insulating moving part 2 and is selectively connected with the conductive part 1 in a conductive way according to the requirement, and the power output part 3 is used for transmitting electric energy outwards; the driving part 4 is used for driving the insulation moving part 2 and the power output part 3 to synchronously slide along the conductive part 1.

Specifically, the conductive member 1 is connected to an external power supply device through a cable to realize remote power transmission through the conductive member 1. The conductive member 1 is disposed to extend along the moving direction of the power output member 3, and the insulating moving member 2 is capable of sliding reciprocally along the extending direction of the conductive member 1, so that the power output member 3 maintains the conductive contact with the conductive member 1, and the sliding mounting manner of the insulating moving member 2 is not limited to contact or non-contact with the conductive member 1. The power output part 3 is mounted on the insulating moving part 2 and moves in synchronization therewith. After the driving part 4 drives the power output part 3 to slide into place and connect with the vehicle, the power output part 3 is electrically connected with the conductive part 1 again to realize the transmission of electric energy to the external electric vehicle. The driving part 4 is connected with the power output part 3 so as to be capable of driving the power output part 3 (and the insulating moving part 2) to slide along the conductive part 1, thereby driving the power output part 3 to approach or depart from a vehicle to be charged. The connection mode of the power output part 3 and the vehicle charging interface is matched and designed according to the structural form of the vehicle charging interface, and the connection and matching mode of the power output part 3 and the vehicle charging interface is not limited and described in detail herein.

In the actual use process, when a vehicle needs to be charged, the driving part 4 drives the power output part 3 and the insulating moving part 2 to synchronously slide along the conductive part 1, and at the moment, the power output part 3 slides out towards the vehicle direction. The electric power output unit 3 is finally caused to interface with the charging interface of the vehicle under the drive of the drive unit 4. Then, the power output part 3 is electrically connected with the conductive part 1 again, so that the power output part 3 can be well supplied with power through the conductive part 1, and the charging stability and reliability are further ensured.

In addition, in the actual use process, according to the matching requirement of the charging vehicle, the charging head 30 with the matching structure is connected to the power output component 3 so as to meet the charging requirement of the vehicle. And the specific structural form of the charging head 30 is not limited.

The conductive part 1 with the power transmission function is adopted to supply power to the power output part 3, so that the technical problem that the requirement of long-distance mobile power supply cannot be met due to the fact that the power supply of a drag chain and a cable is limited by the bending radius is solved, the whole equipment is more compact, the miniaturization design is realized, and the size of the whole equipment is reduced. In addition, the problem that the use safety and reliability of equipment are low due to electric leakage caused by cable damage due to the fact that power is supplied by a cable can be effectively avoided.

Example two

Based on the above technical solution, optionally, for the concrete entity of the power output component 3, various structural forms may be adopted to satisfy that the power output component 3 is selectively and electrically connected with the conductive component 1, and the description is taken in conjunction with the accompanying drawings.

As shown in fig. 2 to 4, the power output section 3 may include: two electromagnets 31 arranged opposite each other, the electromagnets 31 being provided with electrical contact elements 32. The two electromagnets 31 are slidably disposed with respect to the insulating moving member 2, and the electroconductive member 1 is located between the two electromagnets 31. Specifically, during actual use, during the movement of the insulating moving member 2 on the conductive member 1, the two electromagnets 31 generate repulsive forces away from each other, so that the electrical contact elements 32 are away from the conductive member 1. At this time, the electrical contact element 32 is not in contact with the conductive member 1 and is not conductive. When the power output member 3 is moved into position so that the charging head 30 is engaged with the charging port connection of the automobile, the two electromagnets 31 generate attractive forces, so that the electrical contact elements 32 are brought into contact with the conductive member 1 to effect electrical connection. Thus, the charging requirement of the electric vehicle can be met.

In certain embodiments, a resilient support element 311 is also provided between the electrical contact element 32 and the electromagnet 31. Specifically, when the two electromagnets 31 generate attractive force, the elastic support member 311 can ensure that the electric contact member 32 closely contacts the conductive member 1 to improve the conductive reliability. The elastic supporting element 311 may be an insulating compression spring or a rubber cushion block.

Specifically, during actual use, during the movement of the insulating moving member 2 over the conductive member 1, the lifting mechanism 33 acts to move the electrical contact element 32 away from the conductive member 1. At this time, the electrical contact element 32 is not in contact with the conductive member 1 and is not conductive. When the power output part 3 moves to the position to enable the charging head 30 to be connected and matched with the charging port of the automobile, the lifting mechanism 33 acts reversely, so that the electric contact element 32 is contacted with the conductive part 1 to realize electric connection. Thus, the charging requirement of the electric vehicle can be met. The lifting mechanism 33 may have a piston structure such as an air cylinder or an electric push rod.

Preferably, the lifting mechanism 33 comprises: the cam 331, the cam 331 is rotatable with respect to the insulating moving member 2, the cam 331 abuts against the electrical contact element 32 and serves to drive the electrical contact element 32 toward or away from the conductive member 1. Specifically, during the rotation of the cam 331, the electrical contact element 32 can be driven to reciprocate up and down, so as to control the electrical contact element 32 to be far away from the conductive member 1 or close to contact with the conductive member 1. In order to rotate the driving cam 331, a motor (not shown) may be used to drive the driving cam 331, and the driving cam 331 is fixed to a rotating shaft of the motor.

In some embodiments, the lifting mechanism 33 may include: the mounting seat 332, the mounting seat 332 is fixedly arranged on the insulating moving part 2, and the cam 331 is rotatably arranged on the mounting seat 332; at the same time, the electrical contact element 32 is capable of reciprocating relative to the mount 332. In order to enable a reliable resetting of the electrical contact element 32, a tension spring 333 is provided between the electrical contact element 32 and the mounting 332. During rotation of the cam 331, the tension spring 333 enables the electrical contact element 32 to be tightly affixed to the cam 331. In addition, a flexible support plate 334 may be provided between the electrical contact element 32 and the mount 332 in order to support movement of the electrical contact element 32.

The relevant structural component for the driving of the electrical contact element 32 can be mounted on the displacement of the drive component.
