Technical Field
[0001] This utility model belongs to the field of electric vehicle charging technology and relates to a smart control mechanical locking device for preventing misinsertion of a charging gun. Background Technology
[0002] With the rapid popularization of new energy vehicles, charging stations, as an important supporting facility, have attracted much attention regarding the user experience and operational efficiency of their charging piles. Currently, most charging stations use standardized designs for their charging gun sockets and charging gun heads, allowing for easy plugging and unplugging. While this provides some convenience for users, it also creates a prominent problem: when two charging piles are close together, the charging gun heads are easily misplaced. Such misplacement not only prevents users from starting charging normally after scanning the code, or prevents orders from being completed properly after charging, severely impacting the user experience, but also increases communication costs and the risk of disputes between users and operators. To solve this problem, operators need to frequently send staff to check the charging guns' placement one by one, consuming a lot of manpower and resources and driving up maintenance costs.
[0003] Therefore, we propose a smart control mechanical locking device for preventing misinsertion of charging guns. Through a dual protection mechanism of "electronic identification + mechanical blocking", it accurately identifies the compatible charging gun, and the various components work together to intelligently control the locking state, thus achieving reliable prevention of misinsertion. This not only improves the convenience of use for users, but also reduces the cost of manual maintenance. Utility Model Content
[0004] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing an intelligent control mechanical locking device for preventing misinsertion of charging guns. The technical problem to be solved by this utility model is: how to achieve a mechanical locking device that accurately identifies the compatible charging gun through a dual protection mechanism of "electronic identification + mechanical blocking," with each component working together to intelligently control the locking state, thereby reliably preventing misinsertion, which not only improves user convenience but also reduces manual maintenance costs.
[0005] The objective of this utility model can be achieved through the following technical solutions: A smart control mechanical locking device for preventing mis-insertion of a charging gun includes an integrated circuit chip, a charging gun socket, a locking component one, and metal contacts two. The charging gun socket is installed on a charging pile. The locking component one is located at the front end of the charging gun socket. The locking component one has two symmetrical locking components two. Two symmetrical stops are slidably installed on the locking component one. The positions of the locking components two correspond to the stops on the same side. A metal contact one is fixed on the locking component one. The metal contact two is fixed on the insertion end of the charging gun corresponding to the charging gun socket. The position of the metal contact one corresponds to one of the stops. The position and specifications of the metal contact two correspond to those of the metal contact one. The integrated circuit chip is located inside the charging gun. A reading module is located inside the charging gun socket. The metal contact one is electrically connected to the integrated circuit chip, and the metal contact two is electrically connected to the reading module. The reading module, locking component one, and locking component two are all electrically connected to the charging pile controller.
[0006] The working principle of this utility model is as follows: When the charging pile displays that the charging gun is in the charging order active state, the locking component two locks the position of the stop. Other charging guns cannot be inserted into the locking component one and the charging gun socket due to the action of the stop, thus avoiding the misinsertion of other charging guns. When the charging order of the charging pile ends, the locking component two releases the lock on the stop. At this time, when the charging gun is inserted into the locking component one, if the specifications of the charging gun are compatible with the charging gun socket and the locking component one, the charging gun can be inserted into the locking component one. At the same time as insertion, the stop is pushed to move, exposing the metal contact one. The metal contact two on the charging gun will contact the metal contact one on the charging gun socket. The reading module reads the information of the integrated circuit chip through the metal contact one and the metal contact two, and transmits the information to the charging pile controller. After confirming that the charging gun corresponding to this charging gun socket is correctly inserted, the locking component one opens, exposing the charging gun socket, and the charging gun can be smoothly inserted into the charging gun socket and locked in the charging gun socket. If the charging gun specifications are not compatible, it cannot be inserted into locking component one, or the information in the integrated circuit chip on the inserted charging gun cannot be correctly matched with the charging gun socket. In this case, locking component one cannot be opened, and the charging gun cannot be inserted into the charging gun socket, thereby preventing misinsertion and ensuring the normal operation of charging and the correct use of the charging gun. If the charging station controller detects that a charging gun that has completed charging has not been plugged back into the charging gun socket for an extended period of time, it can send a signal to the cloud and send an SMS to remind users and maintenance personnel.
[0007] The locking component one includes a mounting base with two gears rotatably mounted on it. The two gears mesh with each other. A geared motor is fixed on the mounting base, and the output shaft of the geared motor is connected to the rotating shaft of one of the gears. A rocker arm is fixed on each of the two gears, and the two rocker arms are symmetrically arranged. Two symmetrical connecting rods are rotatably mounted on the upper end of the mounting base. A movable part is rotatably mounted on the end of each connecting rod away from the mounting base. The end of the rocker arm away from the gear is rotatably connected to the lower end of the movable part on the same side. A connecting part is fixed on the upper end of the movable part. A locking half-ring is fixed on the side end face of the connecting part facing each other. The specification of the locking half-ring is adapted to the slot end of the charging gun socket. The rear end of the locking half-ring abuts against the inserted end of the charging gun socket. Two stops are slidably mounted on the inner annular sidewalls of the two locking half-rings in the front-back direction. Two locking components two are respectively located inside the two connecting parts. A metal contact one is fixed on the inner annular sidewall of one of the locking half-rings.
[0008] With the above structure, when the charging pile controller issues a command, the geared motor on the mounting base starts, and its output shaft drives one of the gears to rotate. Because the two gears mesh with each other, the other gear rotates synchronously in the opposite direction, thereby causing the two rockers to rotate and open. The rockers cooperate with the connecting rod to drive the two moving parts to move closer or further apart, and the connecting parts move synchronously, thereby driving the two locking half rings to open and close. When the two locking half rings are close together and closed, because their specifications are adapted to the inserted end of the charging gun socket, and their rear ends abut against the inserted end of the charging gun socket, the charging gun socket can be closed and locked. When the two locking half rings are far apart and open, the inserted end of the charging gun socket is exposed, allowing the charging gun to be inserted. At the same time, two stops are slidably set on the inner annular sidewalls of the two locking half rings in the front-back direction. In the initial state, the stops block the metal contact one, which plays a protective role. The two locking components are respectively set inside the two connecting parts to control the sliding of the corresponding stops.
[0009] A slider is fixed on the stop block, and a groove is provided on the locking half ring. The slider passes through the locking half ring on the same side from the groove and is slidably disposed inside the groove. A spring is provided between the rear end of the slider and the groove wall. A moving rod is fixed on the end of the slider located on the outer side of the locking half ring. An clearance opening is provided on the connector, and the moving rod passes through the connector on the same side from the clearance opening. A pin hole is provided on the moving rod.
[0010] With the above structure, the stop block slides in the front-to-back direction through the cooperation of the slider and the slide groove. The slider passes through the locking half ring on the same side of the slide groove. The spring provides the restoring force for the stop block. The moving rod is located inside the clearance opening and has a pin hole. When the second locking component is activated, the moving rod can be locked or unlocked through the pin hole, thereby controlling the sliding state of the stop block. When the charging gun is inserted, it will push the stop block to move backward against the spring force, exposing the first metal contact, which can then contact the second metal contact on the charging gun. When the charging gun is pulled out or not inserted, the stop block returns to its original position under the action of the spring, covering the metal contact again to achieve the protection function.
[0011] The second locking component includes a miniature electric push rod and a blocking pin. The miniature electric push rod is fixed inside the corresponding connector, and the blocking pin is fixed on the telescopic end of the miniature electric push rod. The position and specifications of the blocking pin correspond to the pin hole on the same side.
[0012] With the above structure, when the charging pile controller issues a command, the telescopic end of the miniature electric push rod drives the fixed blocking pin to extend and retract. Since the position and specifications of the blocking pin correspond to the pin hole on the moving rod on the same side, when the blocking pin extends, it will insert into the pin hole, thereby locking the moving rod and preventing the block from sliding. When the blocking pin retracts, it will exit from the pin hole, releasing the lock on the moving rod. The block can then slide in the front and back direction under the push of the charging gun or the action of the spring, thereby realizing the control of the sliding state of the block. Together with the locking component, it completes the anti-misinsertion function.
[0013] The front end of the charging gun socket is equipped with a protective cover, the position and specifications of which correspond to the two locking half rings.
[0014] With the above structure, the protective cover at the front of the charging gun socket is rotated and its position and specifications correspond to the two locking half rings. When the two locking half rings are close to each other and closed, the protective cover can be rotated to cover the front of the locking component one, forming double protection to prevent dust, debris from entering or accidental contact.
[0015] Compared with existing technologies, this intelligent control mechanical locking device for preventing misinsertion of the charging gun has the following advantages: 1. By cooperating with locking component one, the stop block and locking component two, a dual mechanical locking function for the charging gun socket is achieved, completely avoiding usage problems caused by incorrect placement of the charging gun and avoiding poor user experience.
[0016] 2. By cooperating with metal contact one and metal contact two, information interaction between the integrated circuit chip and the reading module is realized. Combined with the mechanical locking of locking component one and locking component two, a dual protection mechanism of "electronic identification + mechanical blocking" is formed, which can accurately identify the compatible charging gun, operate smoothly and respond quickly, and greatly improve the convenience of use.
[0017] 3. The components of this device work together seamlessly and transmit precisely, enabling flexible and intelligent control of the locking half-ring and stop block states. The close linkage and high stability of the components ensure the reliable operation of the anti-misinsertion function. Attached Figure Description

[0026] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0027] like Figure 1 - Figure 7As shown, this intelligent control mechanical locking device for preventing mis-insertion of a charging gun includes an integrated circuit chip, a charging gun socket 2, a locking component 1 3, and a metal contact 2 5. The charging gun socket 2 is installed on the charging pile, and the locking component 1 3 is installed at the front end of the charging gun socket 2. The locking component 1 3 has two left-right symmetrical locking components 2 7. The locking component 1 3 has two left-right symmetrical stops 6 that slide on it. The position of the locking component 2 7 corresponds to the stop 6 on the same side. A metal contact 1 4 is fixed on the locking component 1 3. The metal contact 2 5 is fixed on the insertion end of the charging gun 1 corresponding to the charging gun socket 2. The position of the metal contact 1 4 corresponds to one of the stops 6. The position and specifications of the metal contact 2 5 correspond to the metal contact 1 4. The integrated circuit chip is installed inside the charging gun 1. The charging gun socket 2 has a reading module inside. The metal contact 1 4 is electrically connected to the integrated circuit chip, and the metal contact 2 5 is electrically connected to the reading module. The reading module, the locking component 1 3, and the locking component 2 7 are all electrically connected to the charging pile controller.
[0028] In this embodiment, when the charging pile displays that the charging gun 1 is in the charging order active state, the locking component 2 7 locks the position of the stop 6. Other charging guns 1 cannot be inserted into the locking component 1 3 and the charging gun socket 2 due to the action of the stop 6, thereby avoiding the accidental insertion of other charging guns 1. When the charging order of the charging pile ends, the locking component 2 7 releases the lock on the stop 6. At this time, when the charging gun 1 is inserted into the locking component 1 3, if the specifications of the charging gun 1 are compatible with the charging gun socket 2 and the locking component 1 3, the charging gun 1 can be inserted into the locking component 1 3. At the same time as insertion, the stop 6 is pushed to move, exposing the metal contact 1 4. The metal contact 2 5 on the charging gun 1 will contact the metal contact 1 4 on the charging gun socket 2. The reading module reads the information of the integrated circuit chip through the metal contact 1 4 and the metal contact 2 5, and transmits the information to the charging pile controller. After confirming that the charging gun 1 corresponding to this charging gun socket 2 is correctly inserted, the locking component 1 3 opens, exposing the charging gun socket 2. The charging gun 1 can be smoothly inserted into the charging gun socket 2 and locked in the charging gun socket 2. If the specifications of the charging gun 1 are not compatible, it cannot be inserted into the locking component 3, or the information in the integrated circuit chip on the inserted charging gun 1 cannot be correctly matched with the charging gun socket 2. In this case, the locking component 3 cannot be opened, and the charging gun 1 cannot be inserted into the charging gun socket 2, thereby preventing misinsertion and ensuring the normal operation of the charging operation and the correct use of the charging gun 1. If the charging station controller detects that the charging gun 1, which has completed charging, has not been plugged back into the charging gun socket 2 for an extended period of time, it can send a signal to the cloud and send an SMS to remind the user and maintenance personnel.
[0029] Locking component 3 includes a mounting base 8, on which two gears 9 are rotatably mounted and mesh with each other. A geared motor is fixed on the mounting base 8, and the output shaft of the geared motor is connected to the rotating shaft of one of the gears 9. A rocker arm 10 is fixed to each of the two gears 9, and the two rocker arms 10 are symmetrically arranged. Two symmetrical connecting rods 11 are rotatably mounted on the upper end of the mounting base 8. A movable part 12 is rotatably mounted on the end of each connecting rod 11 away from the mounting base 8. The end of the rocker arm 10 away from the gear 9 is connected to the lower end of the movable part 12 on the same side. The movable part 12 is fixed with a connector 13 at its upper end. Each of the connector 13 has a locking half-ring 14 fixed on one of its facing side faces. The locking half-ring 14 is adapted to the slot end of the charging gun socket 2. The rear end of the locking half-ring 14 abuts against the inserted end of the charging gun socket 2. Two stops 6 are slidably disposed on the inner annular sidewalls of the two locking half-rings 14 in the front-back direction. Two locking components 7 are disposed inside the two connectors 13. A metal contact 4 is fixed on the inner annular sidewall of one of the locking half-rings 14.
[0030] In this embodiment, when the charging pile controller issues a command, the reduction motor on the mounting base 8 starts, and its output shaft drives one of the gears 9 to rotate. Since the two gears 9 mesh with each other, the other gear 9 rotates synchronously in the opposite direction, thereby causing the two rocker arms 10 to rotate and open. The rocker arms 10 cooperate with the connecting rod 11 to drive the two moving parts 12 to move closer or further apart. The connecting parts 13 move synchronously, thereby driving the two locking half rings 14 to open and close. When the two locking half rings 14 are close together and closed, because their specifications are adapted to the inserted end of the charging gun socket 2, and their rear ends abut against the inserted end of the charging gun socket 2, the charging gun socket 2 can be closed and locked. When the two locking half rings 14 are far apart and open, the inserted end of the charging gun socket 2 is exposed, allowing the charging gun 1 to be inserted. At the same time, the two stops 6 are slidably disposed on the annular inner sidewalls of the two locking half rings 14 in the front-back direction. In the initial state, the stops 6 block the metal contact 4, which plays a protective role. The two locking components 7 are respectively disposed inside the two connecting parts 13 to control the sliding of the corresponding stops 6.
[0031] A slider 15 is fixed on the stop block 6. A groove is provided on the locking half ring 14. The slider 15 passes through the locking half ring 14 on the same side through the groove and is slidably disposed inside the groove. A spring 16 is provided between the rear end of the slider 15 and the groove wall. A moving rod 17 is fixed on the end of the slider 15 located on the outer side of the locking half ring 14. An avoidance opening 18 is provided on the connector 13. The moving rod 17 passes through the connector 13 on the same side through the avoidance opening 18. A pin hole 19 is provided on the moving rod 17.
[0032] In this embodiment, the stop block 6 slides in the front-to-back direction through the sliding block 15 and the sliding groove. The sliding block 15 passes through the locking half ring 14 on the same side of the sliding groove. The spring 16 provides the stop block 6 with a reset force. The moving rod 17 is located inside the clearance opening 18. The moving rod 17 has a pin hole 19. When the locking component 2 7 is activated, the moving rod 17 can be locked or unlocked through the pin hole 19, thereby controlling the sliding state of the stop block 6. When the charging gun 1 is inserted, it will push the stop block 6 to move backward against the spring force of the spring 16, exposing the metal contact 1 4, which is convenient to contact the metal contact 2 5 on the charging gun 1. When the charging gun 1 is pulled out or not inserted, the stop block 6 resets forward under the action of the spring 16, and covers the metal contact 1 4 again to provide protection.
[0033] Locking component 27 includes a miniature electric push rod 20 and a blocking pin 21. The miniature electric push rod 20 is fixed inside the corresponding connector 13, and the blocking pin 21 is fixed on the telescopic end of the miniature electric push rod 20. The position and specifications of the blocking pin 21 correspond to the pin hole 19 on the same side.
[0034] In this embodiment, when the charging pile controller issues a command, the telescopic end of the miniature electric push rod 20 drives the fixed blocking pin 21 to extend and retract. Since the position and specifications of the blocking pin 21 correspond to the pin hole 19 on the same side of the moving rod 17, when the blocking pin 21 extends, it will insert into the pin hole 19, thereby locking the moving rod 17 and preventing the stop block 6 from sliding. When the blocking pin 21 retracts, it will exit from the pin hole 19, releasing the lock on the moving rod 17. The stop block 6 can then slide in the front and back direction under the push of the charging gun 1 or the action of the spring 16, thereby realizing the control of the sliding state of the stop block 6 and completing the anti-misinsertion function in conjunction with the locking component 3.
[0035] The front end of the charging gun socket 2 is equipped with a protective cover 22, the position and specifications of which correspond to the two locking half rings 14.
[0036] In this embodiment, the protective cover 22, which is rotatably mounted on the front end of the charging gun socket 2, corresponds to the position and specifications of the two locking half rings 14. When the two locking half rings 14 are close to each other and closed, the protective cover 22 can be rotated to cover the front end of the locking component 3, forming double protection to prevent dust, debris from entering or accidental contact.
[0037] The working principle of this utility model is as follows: When the charging pile displays that the charging gun 1 is in the charging order active state, the telescopic end of the micro electric push rod 20 in the locking component 2 7 drives the blocking pin 21 to extend and insert into the pin hole 19 on the moving rod 17, locking the moving rod 17 and preventing the stop block 6 from sliding. Other charging guns 1 cannot be inserted into the locking component 1 3 and the charging gun socket 2 due to the block block 6, thus avoiding misinsertion. When the charging order ends, the micro electric push rod 20 drives the blocking pin 21 to retract, releasing the lock on the moving rod 17. At this time, if a compatible charging gun 1 is inserted into the locking component 1 3, it will push the stop block 6 to move backward against the spring force of the spring 16, exposing the metal contact 1 4. The metal contact 2 5 on the charging gun 1 contacts it. The reading module reads the information of the integrated circuit chip in the charging gun 1 through both and transmits it to the charging pile controller. After confirming the match, the controller instructs... The geared motor on the mounting base 8 of the locking assembly 3 is started, driving one of the gears 9 to rotate. Since the two gears 9 mesh with each other, the other gear 9 rotates synchronously in the opposite direction, causing the rocker arm 10 to rotate and cooperate with the connecting rod 11, driving the moving part 12 and the connecting part 13 to move away from each other, thereby opening the locking half ring 14, exposing the charging gun socket 2, and the charging gun 1 can be smoothly inserted and locked. If the charging gun 1 is not of the correct specification, it cannot be inserted into the locking assembly 3, or if the information is mismatched, the locking assembly 3 cannot be opened. When the locking half ring 14 is closed, the protective cover 22 rotates to cover its front end to form double protection, thereby preventing misinsertion and ensuring normal use of the equipment. If the charging pile controller detects that the charging gun 1, which has completed charging, has not been inserted back into the charging gun socket 2 for a long time, it can send a signal to the cloud and send a text message to remind the user and maintenance personnel.
[0038] In summary, by cooperating with locking component 1 3, stop 6 and locking component 2 7, a dual mechanical locking function for the charging gun socket 2 is achieved, completely avoiding usage problems caused by incorrect placement of the charging gun 1 and avoiding poor user experience. The information interaction between the integrated circuit chip and the reading module is realized through the cooperation of metal contact 1 4 and metal contact 2 5. Combined with the mechanical locking of locking component 1 3 and locking component 2 7, a dual protection mechanism of "electronic identification + mechanical blocking" is formed, which can accurately identify the compatible charging gun 1, and the operation is smooth and the response is fast, greatly improving the convenience of use. The components of this device work together seamlessly and transmit precisely, enabling flexible and intelligent control of the locking half-ring 14 and the stop block 6. The close linkage and high stability of the components ensure the reliable operation of the anti-misinsertion function.
