The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment.

The present embodiment provides a protection mechanism for a charging pile, as shown in fig. 1 and 2, which includes a base 1, a charging head 2 disposed on the base 1, a protection cover 3 disposed on the base 1, and an elastic member 4 disposed between the base 1 and the protection cover 3. Wherein the shield 3 is reciprocally movable between a first position and a second position relative to the base 1. The shield 3 is located outside the charging head 2 when being located the first position, and the shield 3 is provided with the uncovered that is used for dodging the charging head 2 in the slip in-process, and when the shield 3 is located the second position, the charging head 2 protrusion extremely outside the uncovered. The elastic member 4 presses the shield 3 in such a manner that the shield 3 has a tendency to move toward the first position.

Compared with the active protection scheme that an electric driving mechanism is used for driving the charging head to stretch out and draw back in the related art, the protection mechanism provided by the application can play a passive protection role on the charging head of the charging pile. When the external device to be charged needs to be charged and approaches the charging head 2, the pressing action of the external device to be charged on the protective cover 3 pushes the protective cover 3 to act relative to the base 1, so that the charging head 2 is exposed for charging. After the charging is completed, the external equipment is removed, and the protective cover 3 acts relative to the base 1 under the action of the pressure of the elastic piece 4 to restore to the original position. Since the elastic member 4 presses the shield 3 with a tendency to move toward the first position, the shield 3 maintains good stability with respect to the base 1 under the action of the elastic member 4 when the charging operation is not performed, and has a good protective effect on the charging head 2. The scheme provided by the application does not need a complex electric driving structure, and has the advantages of low cost, small occupied space and simpler structure.

The charging head can be fixedly mounted to the base through the support structure, i.e., the charging head can be fixed relative to the base; or a floating mechanism can be arranged between the charging head and the bracket, so that the charging head can slightly move relative to the base under the action of external force. The arrangement mode of the charging head is the prior art, and is not repeated here.

The protection cover 3 in the protection mechanism provided in the present embodiment is slidably disposed on the base 1, and the protection cover 3 can be reciprocally slid with respect to the base 1 in a set direction, that is, the protection cover 3 is linearly slid. In order to achieve the above functions, the protection mechanism provided in this embodiment further includes a guide assembly, where the guide assembly includes a guide rail and a chute that are adapted, one of the guide rail and the chute is disposed on the protection cover, and the other one is disposed on the base. Through the cooperation of guide rail and spout, can guarantee that the protection casing can slide along the settlement direction that the direction subassembly was limited to relative base. It will be readily appreciated that in alternative embodiments, the shield may be otherwise enabled to slide relative to the base in a set direction. For example, the shield may be mounted on both sides of the whole shield in the set direction, and the sliding direction of the shield may be restricted by the cooperation of the both side shields. Or the ability of the elastic piece to resist bending deformation can be directly utilized to ensure that the protective cover can slide relative to the base along the set direction. The set direction in this embodiment refers to a plugging direction in which the charging head and the charging port of the device to be charged are plugged.

Further, as shown in fig. 3, 4 and 5, the guide rail 5 is selectively fixed on the base 1, and the chute is correspondingly arranged on the protective cover 3. Specifically, in this embodiment, a long-strip guide rail 5 is fixedly mounted on the base 1 by using a bolt, a slide block 6 is provided at the bottom of the protective cover 3, and the slide groove is provided on one side of the slide block 6 facing the guide rail 5. The slider 6 may be directly and fixedly mounted on the bottom of the protective cover 3 by welding or bolting, but considering that the protective cover 3 itself does not need too thick material, in order to ensure the connection strength, in this embodiment, the elongated connecting plate 32 is fixedly mounted on the bottom of the protective cover 3, and the slider 6 is fixedly mounted on the connecting plate 32. Specifically, the protection cover 3 in the present embodiment includes a top plate 30, side plates 31 disposed at both sides of the top plate 30, and a rim 310 formed on the side plates 31, the connection plate 32 is fixedly connected to a side of the rim 310 facing the guide rail 5 by bolts, and then the slider 6 is fixedly mounted to the connection plate 32 by bolts.

As mentioned above, the slide 6 is provided with a slide groove, which is adapted to the guide rail 5. Alternatively, elongated grooves may be provided on both sides of the guide rail 5, and corresponding flanges adapted to the grooves may be provided on both sides of the slider 6. This arrangement can further enhance the guiding capability of the guiding assembly by the cooperation of the flange and the groove, so that the sliding of the shield 3 in the set direction is more stable.

As shown in fig. 2, 3 and 4, the elastic member 4 in the present embodiment is a coil spring, one end of which is fixedly provided to the shield 3, and the other end of which is provided to the base 1 through a coil spring holder. Thus, when the shield 3 is externally pressed to slide from the first position to the second position, one end of the coil spring is driven to move, the coil spring arranged around is pulled out and stretched, and the coil spring can accumulate elastic potential energy in the process. After the external pressure is removed, elastic potential energy accumulated by the coil spring is applied to the protective cover 3 to drive the protective cover 3 to slide and reset from the second position to the first position, and the coil spring is retracted. In addition, the selection of using a coil spring as the elastic member 4 can continuously provide a large restoring force in a small space without being affected by the stroke of the shield 3.

In this embodiment, the coil springs are arranged side by side with the shield 3, which has the advantage that the size of the shield mechanism in the set direction can be reduced. As shown in fig. 4, the protection mechanism provided by the present embodiment further includes a connection member 7, and the connection member 7 includes a first connection arm 70 for fixedly connecting with the protection cover 3 and a second connection arm 71 for fixedly connecting with one end of the coil spring. Wherein the first connecting arm 70 and the second connecting arm 71 intersect, in particular in the present embodiment, the first connecting arm 70 and the second connecting arm 71 are perpendicular to each other, so that the connecting member is L-shaped. By providing the connection 7, a side-by-side arrangement of the coil spring and the shield 3 is achieved. Specifically, the first connecting arm 70 is fixedly mounted to the connecting plate 32 by bolts, and one end of the coil spring is fixedly connected to the second connecting arm 71 by bolts.

In other alternative embodiments, a compression spring or a metal spring plate may be used as the elastic member.

In addition, in order to prevent excessive sliding of the shield due to continuous external pressure, a stopper 10 for limiting the sliding stroke of the shield 3 is also provided on the base in this embodiment. Specifically, in this embodiment, the limiting block 10 is directly and fixedly connected to the base 1 through a bolt, and the limiting block 10 is matched with the second connecting arm 71 of the connecting piece 7 to realize a limiting function. In an alternative embodiment, the limiting block may also be fixedly mounted on a sliding rail provided on the base, and correspondingly, the limiting block may also be matched with the sliding block or the first connecting arm of the connecting piece to realize the limiting function.

In this embodiment, a guide wheel 33 is further disposed on the front portion of the protection cover 3 along the set direction, the guide wheel 33 is rotatably disposed on the protection cover 3, and the guide wheel 33 is used for guiding the external device to be charged to press the protection cover 3. Through setting up guide pulley 33, at the outside in-process that the equipment that waits to charge is close to charging head 2, usable guide pulley 33 will be outside wait to charge the effort transmission of equipment to protection casing 3, reduce the outside and wait to charge the direct collision, the striking of equipment to protection casing 3, prevent that protection casing 3 from being destroyed.

As described above, the protection cover in the protection mechanism provided in this embodiment can slide reciprocally between the first position and the second position relative to the base along the set direction, and in other alternative embodiments, the protection cover may be configured to rotate relative to the base to implement reciprocal movement between the first position and the second position. For example, the protection cover is designed into a cover body in a sphere-shaped shape and is connected to the base through the rotating shaft in a rotating way, in this case, the elastic piece preferably uses a torsion spring, when the protection cover is pressed by the outside, the protection cover can rotate relative to the base to expose the charging head, and after the external pressure is eliminated, the protection cover can return to the original position under the action of the torsion spring to continue to protect the charging head.

As shown in connection with fig. 1 and 6, the protection mechanism provided by the present embodiment may be applied to a charging pile including a power source and the protection mechanism provided by the present embodiment, wherein the charging head 2 is electrically connected with the power source. Further, the charging pile further comprises a housing 8, the power supply and the base 1 are both arranged in the housing 8, the housing 8 is provided with an opening 80 for the protective cover 3 to extend in and out, and the charging head 2 extends out of the housing 8 through the opening 80.

Referring to fig. 7 and 8, in this embodiment, the working principle of the protection mechanism is further described by taking the charging pile as an example of charging for an AGV (automatic guided vehicle):

When the control module detects that the automatic guided vehicle 9 (AGV) needs to be charged, the control module controls the AGV to move to a specified position (the position of the charging pile), and the AGV automatically guides the charging port 90 on the AGV to align and plug the charging head 2 on the charging pile through a built-in program after the AGV approaches the charging pile. The outer shell 8 of the AGV will first contact the guide wheel 33 on the protection mechanism and apply force to the guide wheel 33, thereby pushing the shield 3 to slide in the direction opposite to the set direction. In this process, the charging head 2 is gradually exposed, and the charging head 2 is gradually inserted into the charging port 90. The AGV stops after reaching the designated charging position, at which time the protection mechanism slides to the second position, and the charging head 2 is fully inserted into the charging port 90 to achieve good contact, and charging begins. After the charging is completed, the AGV executes other tasks to leave the charging pile, after external pressure is lost, the coil spring releases elastic potential energy and pushes the protection cover 3 to the first position, and the protection cover 3 continues to protect the charging head 2 at the first position.

The above is only a specific embodiment of the present application, but the scope of the present application is not limited thereto, and it should be understood by those skilled in the art that the present application includes but is not limited to the accompanying drawings and the description of the above specific embodiment. Any modifications which do not depart from the functional and structural principles of the present application are intended to be included within the scope of the appended claims.
