Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, specifically to a charging pile with a self-locking function. Background Technology

[0002] Charging piles, as a key supporting facility for new energy vehicles, mainly consist of two parts: the pile itself and the charging gun. The pile itself, as the fixed power supply unit, is electrically connected to the charging gun via a charging interface; the charging gun, as a movable connecting component, undertakes the important function of transmitting electrical energy from the pile to the vehicle's battery system. The two are coupled mechanically and electrically through a standardized interface.

[0003] In actual use, the charging gun needs to be connected to the charging station or vehicle charging port through plugging and unplugging. This connection method carries the risk of accidental disconnection, which may be caused by external impact, vibration, or human error. There is even a safety hazard of being maliciously disconnected by others, directly affecting the continuity and safety of the charging process. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model proposes a charging pile with a self-locking function, which solves the technical problem of the charging gun unexpectedly detaching from the vehicle or the charging pile in existing technologies.

[0005] The technical solution adopted in this utility model is: a charging pile with a self-locking function, comprising: The charging pile and the charging cable are pluggable to the end of the charging pile and / or the end of the vehicle via a self-locking structure. The self-locking structure includes a wire end housing, a locking rod, and a locking rod driving mechanism. The end face of the wire end housing is provided with a locking rod hole. The locking rod body is rotatably disposed inside the wire end housing. The head end of the locking rod passes through the locking rod hole and is provided with a locking hook. The locking rod driving mechanism is disposed at the tail end of the locking rod and can drive the locking rod to flip.

[0006] Optionally, the locking rod driving mechanism includes a connecting rod and a trigger block. The trigger block is slidably disposed in the wire end housing. One end of the connecting rod is hinged to the tail end of the locking rod, and the other end is hinged to the trigger block. The sliding of the trigger block can drive the locking rod to rotate.

[0007] Optionally, the trigger block is partially exposed outside the wire end housing; or, the trigger block is a telescopic power source, with the telescopic shaft hinged to the connecting rod.

[0008] Optionally, the trigger block is rotatably connected to a screw at its tail end, the screw being threaded into the wire end housing and extending out of the outside of the wire end housing.

[0009] Optionally, where the screw protrudes from the wire end housing, a cover is provided that connects to the wire end housing and covers the screw.

[0010] Optionally, the structure of the threaded engagement area between the wire end housing and the screw is connected to the wire end housing body through a weak structure.

[0011] Optionally, the weak structure is a material thinning structure located around the mating area between the screw and the wire end housing.

[0012] Optionally, it also includes a pull cable and a fixing ring, the fixing ring being fixedly connected to the outer sheath of the charging cable, the pull cable being fixedly connected to the tail end of the locking rod, and when the charging cable moves along the tail end of the cable end housing, it can pull the locking rod to flip and unlock.

[0013] Optionally, a reversing post is provided on the path of the cable, the front end of the cable is flipped and unlocked along the locking rod, and the rear end of the cable is extended along the charging cable.

[0014] Optionally, the outer sheath of the charging cable is interference-fitted with the tail end of the cable end housing.

[0015] As can be seen from the above technical solution, the beneficial technical effects of this utility model are as follows: The self-locking charging pile proposed in this solution uses a self-locking structure at the connection between the charging cable and the pile end and / or the vehicle end. The locking rod is driven by a locking rod drive mechanism to rotate the locking rod, so that the locking hook and the corresponding interface are reliably locked. This effectively solves the technical problem in the prior art that the charging gun is prone to unexpectedly coming off due to external force or human factors such as grabbing the pile. It ensures the connection stability during the charging process, significantly improves the safety of use, and avoids the risk of charging interruption caused by accidental disconnection or malicious pulling.

[0024] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0025] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0026] A charging station with a self-locking function; please refer to the appendix. Figure 1 and Figure 2 One possible implementation is as follows: a charging pile 1 and a charging cable 2, wherein the charging cable 2 is pluggably connected to the end of the charging pile and / or the end of the vehicle via a self-locking structure; the self-locking structure includes a cable end housing 3, a locking rod 4 and a locking rod driving mechanism 5, wherein the end face of the cable end housing 3 is provided with a locking rod hole, the body of the locking rod 4 is rotatably disposed in the cable end housing 3, the head end of the locking rod 4 passes through the locking rod hole and is provided with a locking hook 41, and the locking rod driving mechanism 5 is disposed at the tail end of the locking rod 4 and is capable of driving the locking rod 4 to rotate.

[0027] A matching latch is provided at the pile end or vehicle end that mates with the line end housing 3. Before the line end housing 3 is inserted into the pile end or vehicle end, the locking rod drive mechanism 5 causes the locking rod 4 to rotate clockwise by a certain angle (e.g., Figure 3 (As shown); after the line end housing 3 is inserted into the pile end or vehicle end, the locking rod drive mechanism 5 causes the locking rod 4 to rotate counterclockwise by a certain angle (e.g. Figure 4 As shown), at this time, the locking hook 41 at the end of the locking rod 4 engages with the locking buckle at the pile end or vehicle end, thus the charging gun and the pile end or vehicle end form a self-locking mechanism, and the two cannot be separated.

[0028] The above embodiments provide a charging pile with a self-locking function. This charging pile mainly consists of a pile body and a charging cable. The charging cable is pluggably connected to the pile body and / or the vehicle end via a self-locking structure. This self-locking design has many beneficial effects. For the charging cable and charging pile end, it effectively prevents unauthorized removal of the charging cable and charging gun, ensuring the integrity of the charging equipment. Simultaneously, maintenance personnel can easily replace the charging cable when necessary. For the charging gun and vehicle end, it prevents the charging gun from being pulled out by others during charging, avoiding charging interruptions caused by accidental removal, improving the safety and stability of the charging process, and providing users with a more reliable charging service.

[0029] In one possible implementation, see Appendix Figure 5 The locking lever drive mechanism 5 includes a connecting rod 51 and a trigger block 52. The trigger block 52 is slidably disposed within the wire end housing 3. One end of the connecting rod 51 is hinged to the tail end of the locking lever 4, and the other end is hinged to the trigger block 52. The hinge points at both ends of the connecting rod 51 can move freely without being connected to the wire end housing 3. The sliding of the trigger block 52 can cause the locking lever 4 to rotate. When the trigger block 52 slides, it will push the tail end of the locking lever 4 to rotate around its rotation axis through the connecting rod 51, thereby causing the locking hook 41 at the other end to rotate, thus achieving unlocking or locking.

[0030] Specifically, in one possible implementation, see Appendix Figure 5 The trigger block 52 is partially exposed outside the wire end housing 3; or, the trigger block 52 is a telescopic power source (such as an electric push rod), and the telescopic shaft 521 of the telescopic power source is hinged to the connecting rod 51.

[0031] When the trigger block 52 is partially exposed outside the wire end housing 3, the unlocking and locking operations are performed manually by the operator. By pressing the trigger block 52, the trigger block 52 can slide into the wire end housing 3, pushing the connecting rod 51 upward to move it, thereby pushing the connecting rod 51 to flip, thus locking the locking hook 41. When the telescopic power source is used, the unlocking and locking states are switched by the telescopic power source. Its principle is the same as the manual mode, except that the power that causes the trigger block 52 to slide is different.

[0032] In one possible implementation, see Appendix Figure 5 The trigger block 52 is rotatably connected to a screw 522 at its tail end. When the screw 522 rotates, the trigger block 52 will not rotate. When the screw 522 moves axially, the trigger block 52 moves accordingly. The screw 522 is threadedly engaged with the wire end housing 3 and passes through the outside of the wire end housing 3.

[0033] This design brings significant and beneficial technical effects. In actual use, if the telescopic power source malfunctions, preventing the charging gun from unlocking properly, the operator will not be in a predicament. In this case, the operator simply needs to manually turn the screw 522 protruding from the outer side of the cable end housing 3, moving the screw 522 backward. Since the trigger block 52 is connected to the screw 522 and moves with it, it can pull the telescopic power source backward, achieving manual forced unlocking. This design effectively avoids situations where the charging gun and vehicle cannot be unlocked due to a malfunction in the telescopic power source, greatly improving the convenience and flexibility of use and ensuring a good user experience.

[0034] Furthermore, where the screw 522 protrudes from the cable end housing 3, a cover 31 is provided, connected to the cable end housing 3. The cover 31 connects to the cable end housing 3 and shields the screw 522. The cover 31 can be a removable cover (similar to the remote control battery cover) or a sticker label. This design brings good technical results. Under normal use of the charging pile, the cover 31 can effectively prevent the screw 522 from being accidentally operated. Because of the cover's shielding, the user will not easily touch the screw 522, thus avoiding accidental unlocking of the charging pile's self-locking structure or other abnormal situations due to accidental operation. In case of emergency such as a failure of the telescopic power source, requiring manual forced unlocking, the operator can easily remove the cover 31 to operate the screw 522, ensuring that the charging gun and vehicle body can be unlocked smoothly, ensuring the availability of the charging equipment in special circumstances. The cover 31 and sticker label can be made into a one-time use structure, destroyed upon removal, ensuring that the user only uses them when necessary.

[0035] In one possible implementation, see Appendix Figure 6 The structure of the threaded engagement area between the wire end housing 3 and the screw 522 is connected to the main body of the wire end housing 3 via a weak structure 32. The weak structure 32 is a material thinning structure located around the engagement area between the screw 522 and the wire end housing 3. It also includes a pull cable 53 and a fixing ring 54. The fixing ring 54 is fixedly connected to the outer sheath 21 of the charging cable 2, and the pull cable 53 is fixedly connected to the tail end of the locking rod 4. When the charging cable 2 moves along the tail end of the wire end housing 3, it can pull the locking rod 4 to flip and unlock. (See appendix) Figure 6 A reversing post 33 is provided along the path of the cable 53. The front end of the cable 53 flips and unlocks along the locking rod 4, and the rear end of the cable 53 extends along the charging cable 2. The outer sheath 21 of the charging cable 2 is interference-fitted with the tail end of the cable end housing 3.

[0036] In the above embodiment, the peripheral structure of the threaded engagement area between the wire end housing 3 and the screw 522 and the main body of the wire end housing 3 are connected by a weak structure 32. This weak structure 32 is a material thinning structure located around the engagement area between the screw 522 and the wire end housing 3. Simultaneously, a pull cable 53 and a fixing ring 54 are provided. The fixing ring 54 is fixed to the outer sheath 21 of the charging cable 2, and the pull cable 53 is fixed to the tail end of the locking rod 4. A reversing post 33 is present along the path of the pull cable 53, with its front end along the unlocking direction of the locking rod 4 and its rear end along the extension direction of the charging cable 2. The outer sheath 21 of the charging cable 2 and the tail end of the wire end housing 3 are interference-fitted.

[0037] When a vehicle drives away without removing the charging gun, the charging cable is subjected to significant pulling force. Since the charging gun's housing is integrated with the vehicle, the interference fit 6 is first disrupted (the outer insulation layer of the charging cable has a certain elasticity, generating significant friction through compression to connect with the housing; under high tension, this friction is overcome), causing the charging cable to move backward relative to the charging gun's housing. This backward movement of the charging cable causes the fixing ring 54 to move backward, which in turn pulls the cable 53. Under this force, the cable 53 pulls the locking lever 4 to flip and unlock. The force generated by the flipping of the locking lever 4 reacts to the telescopic power source. If the telescopic power source cannot extend or retract, its weak mounting structure 32 will be damaged by the force, ensuring the telescopic power source can move backward, the locking lever 4 can flip, and the locking hook's locking mechanism fails. Ultimately, the charging gun separates from the vehicle, effectively preventing the vehicle from forcibly pulling the charging cable and charging station, reducing the danger caused by pulling, ensuring the safety of the charging equipment and surrounding environment, and improving the safety and reliability of the charging process.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
