[0038] In an embodiment of the present application, the rolling elements include ball bearings.

[0039] In an embodiment of the present application, the telescopic charging device realizes the extension of the floating electrode assembly through the linear motion mechanism for charging, and drives the retraction of the floating electrode assembly through the retraction of the linear motion mechanism after charging is completed.

[0040] In an embodiment of the present application, static friction can be maintained after losing power during the entire telescopic stroke, but it belongs to non-self-locking retention, so that the floating electrode assembly can follow and retract in the extended state, and avoid structural damage under the condition of completely or partially bearing uncontrolled external forces.

[0041] In an embodiment of the present application, the telescopic charging device further includes an electronic control system, a frame, a three-degree-of-freedom adjustment base, and a foundation.

Among them, the lead screw stepping motor shaft in the driving telescopic component 505 retreats while rotating, driving the retaining tongue 508 to retreat. After the retaining tongue 508 withdraws, the counterweight 503 loses support and falls freely, pulling the traction assembly 501 to pull the electrode assembly mounting plate 506 back, causing the floating electrode assembly to retract to a safe position, thus completing the self-resetting. In addition, the counterweight is constrained within its own range by the first limiting component 504 during the entire falling process.

[0051] In an embodiment of the present application, the device to be charged includes an Automated Guided Vehicle (AGV).

[0052] In an embodiment of the present application, please refer to Figure 6 , Figure 6 shows a front view schematic diagram of the power receiving electrode assembly according to an embodiment of the present application.

As Figure 8 shown, the power receiving electrode assembly includes a second insulating plate 810; the second insulating plate 810 includes a support surface 811 and a progressive inclined guide 812. Among them, the solid line arrow is used to represent the movement direction of the power receiving device, the dashed line arrow is used to represent the force direction of the floating electrode assembly, point A is used to represent the earliest contact surface between the floating electrode assembly and the progressive inclined guide, and point B is used to represent the retracted position of the floating electrode assembly. The linear motion mechanism of the telescopic charging device in the abnormal extended state is gradually pushed by the progressive inclined guide 812 to follow and retract, driving the floating electrode assembly to gradually retract from point A to point B.

[0056] In an embodiment of the present application, if the external force received by the linear motion mechanism is greater than the static friction force, the forced following retraction function of the linear motion mechanism can be realized, thereby driving the floating electrode assembly to retract.

[0057] In an embodiment of the present application, the power receiving device has a progressive inclined guide in the direction of entering and exiting the charging work point, and can gradually push the linear motion mechanism in the telescopic charging device in the abnormal extended state to follow and retract, thereby retracting the floating electrode assembly.

[0058] In an embodiment of the present application, before the vehicle to be charged enters the charging work point, even if there is physical interference with the telescopic charging device, when the interference actually occurs, the linear motion mechanism of the telescopic charging device can be forced to follow and retract, thereby retracting the floating electrode assembly.

[0059] In an embodiment of the present application, please refer to Figure 9 , Figure 9 which shows an internal schematic diagram of the telescopic charging device according to an embodiment of the present application. As Figure 9 shown, the linear motion mechanism 901 is located above the gravity self-resetting mechanism 902, and the floating electrode assembly 903 is located on the side of the linear motion mechanism 901.

[0060] Please refer to Figure 10 , Figure 10 which shows a schematic flow diagram of the control method of the telescopic charging device according to an embodiment of the present application. As Figure 10 shown, in an exemplary embodiment, the control method of the telescopic charging device at least includes steps S1010 to step S1030, which are introduced in detail as follows:

[0061] Step S1010, detect the working state of the telescopic charging device.

[0062] Among them, the telescopic charging device includes a linear motion mechanism, a gravity self-resetting mechanism, and a floating electrode assembly.

[0063] Step S1020, if the working state is the first type of abnormality, retract the linear motion mechanism by the external force received to drive the floating electrode assembly to retract.

[0064] In an embodiment of the present application, if the working state is the first type of abnormality, retracting the linear motion mechanism by the external force received includes: if the first type of abnormality is that the linear motion mechanism loses power, the loss of power is not caused by the power failure of the telescopic charging device, and the retraction of the linear motion mechanism does not exceed the time limit, then retract the linear motion mechanism by the external force received.

[0065] Step S1030, if the working state is the second type of abnormality, retract the linear motion mechanism by the pulling of the counterweight in the gravity self-resetting mechanism to drive the floating electrode assembly to retract.

[0066] In an embodiment of the present application, if the working state is the second type of abnormality, retracting the linear motion mechanism by the pulling of the counterweight in the gravity self-resetting mechanism includes: if the second type of abnormality is that the retraction of the linear motion mechanism exceeds the time limit, start the driving telescopic component to retract based on a preset instruction; if the second type of abnormality is that the telescopic charging device loses power, drive the telescopic component to retract in the power-off state; by driving the retraction of the telescopic component, drive the tongue to retreat, and make the counterweight without the support of the tongue fall, pulling and retracting the linear motion mechanism; among them, the gravity self-resetting mechanism includes a driving telescopic component and a tongue, and the control priority of the second type of abnormality is higher than that of the first type of abnormality.

[0067] In an embodiment of the present application, when the telescopic charging device suddenly loses power, even if the passive retraction function of the floating electrode assembly can be forced to follow and retract through the linear motion mechanism, the active retraction function corresponding to the gravity self-resetting mechanism is still enabled.

[0068] In an embodiment of the present application, the first way to start the gravity self-resetting mechanism includes: if the electronic control system detects that the retraction of the linear motion mechanism exceeds the time limit, actively issue a preset instruction to start the driving telescopic component to retract.

[0069] In an embodiment of the present application, the second way to start the gravity self-resetting mechanism includes: after the telescopic charging device loses power, the driving telescopic component loses power at the same time, and the driving telescopic component itself retracts.

[0070] In one embodiment of the present application, when the driving telescopic member retracts, it drives the tongue to retract. The counterweight freely falls under the action of gravity, and pulls the linear motion mechanism to retract through the traction assembly, thereby driving the floating electrode assembly to retract.

[0071] In one embodiment of the present application, the pulling method of the counterweight is constant force pulling.

[0072] In one embodiment of the present application, according to the fail-safe guidance, in the case of power failure of the telescopic charging device, the linear motion mechanism can still be retracted by using gravitational potential energy.
