The embodiment provides an electronic lock 10, which is used for solving the problems that the existing electronic lock is low in reliability and large in size, the manual unlocking operation is complex in an abnormal charging state of a vehicle, and the parts in the vehicle body are interfered due to the following rotation of an operating handle during the electric locking and unlocking.

Referring to fig. 1 and 2, fig. 1 shows a specific structure of an electronic lock 10 in a first view angle in this embodiment. Fig. 2 shows a specific structure of the electronic lock 10 in the second view angle in this embodiment.

The electronic lock 10 includes a housing 11 (where fig. 1 shows a diagram of the electronic lock 10 in the presence of the housing 11. To facilitate clear understanding of the specific structure of the electronic lock 10, fig. 2 is a diagram of the electronic lock 10 with the housing 11 removed), an unlocking slide 12, a locking slide 13, a lock tongue 14, a driving unit 15, a reset mechanism 16, and an unlocking unit 17, and the housing 11 has a housing cavity therein with an unlocking rail (explained in detail below). The unlocking slide 12 is configured to be movably disposed in an unlocking rail, and the unlocking slide 12 has a locking rail (explained in detail below). The lock slider 13 is engaged with a lock rail in which the lock slider 13 is configured to reciprocate. The lock tongue 14 is connected to the lock slider 13, and at least a part of the lock tongue 14 penetrates the housing 11. The driving unit 15 is arranged in the accommodating cavity and is in transmission connection with the locking slide block 13, and the driving unit 15 drives the locking slide block 13 to reciprocate along the locking track. The return mechanism 16 is provided in the unlocking rail, and the return mechanism 16 is configured to maintain the relative position of the unlocking slide 12 and the housing 11 by an elastic force. A portion of the unlocking unit 17 is located in the accommodating cavity and connected with the unlocking slide 12, and a portion of the unlocking unit 17 penetrates the housing 11 and is exposed outside the housing 11.

The electronic lock 10 is used for locking a charging interface when a vehicle is charged, wherein the electronic lock 10 in the above scheme can drive the electronic lock 10 to lock and unlock in an unmanned manner, and can unlock the electronic lock 10 in an unmanned manner in an abnormal state. Wherein, the operation is driven in a non-artificial way (which can be understood as normal) as follows: the driving unit 15 drives the locking slide block 13 to reciprocate along the locking track in a mode of jointly matching the driving unit 15, the unlocking slide block 12 and the locking slide block 13, and meanwhile, under the motion of the locking slide block 13, the lock tongue 14 moves along with the locking slide block 13 to complete the locking and unlocking process (wherein, it is required to be noted that the lock tongue 14 is matched with an external charging gun, so that the locking and unlocking between the electronic lock 10 and the external charging gun are realized). Unlocking takes place in an artificial way (which can also be understood as in case of emergency): by manually driving the unlocking unit 17 (e.g., pulling a portion of the unlocking unit 17 exposed outside the housing 11), the unlocking slider 12 is enabled to overcome the elastic force of the reset mechanism 16 and move on the unlocking track, so that the locking slider 13 and the lock tongue 14 follow the unlocking slider 12 to move together, thereby enabling the electronic lock 10 to exit the locked state, and unlocking is achieved. Meanwhile, by means of the reset mechanism 16, the relative position between the unlocking slide 12 and the housing 11 can be maintained in an unmanned manner (which can be understood as normal), so that the locking slide 13 can be locked and unlocked normally under the drive of the drive unit 15. It should be noted that, the force applied by the reset mechanism 16 to the unlocking slide 12 can make the locking slide 13 not receive external force, or explain that the locking slide 13 can keep relatively static state with respect to the housing 11 when not receiving a certain amount of external force, so as to ensure normal operation of the electronic lock 10 in a non-artificial manner (also can be understood as normal condition), and in an emergency, a force capable of overcoming the force of the reset mechanism 16 to the unlocking slide 12 and driving the unlocking slide 12 to move needs to be applied, so as to realize manual unlocking. It should be noted that, in this embodiment, the relative positional relationship between the locking track and the unlocking track is not limited, and may be parallel, collinear or inclined, and one possible implementation is shown in fig. 2, where the locking track and the unlocking track are in the same direction, and under the condition of implementing the above function, when the unlocking slider 12 moves in the unlocking track, the locking slider 13 can move along the locking track and achieve unlocking, for example, in other specific embodiments, the locking track and the unlocking track are inclined, and when the unlocking slider 12 moves in the unlocking track, the direction of movement of the locking slider 13 only needs to move along the unlocking track, that is, the locking track has the direction of movement same as the unlocking track.

Further, referring to fig. 3, fig. 3 shows a specific structure of the unlocking slide 12 and the locking slide 13 in the present embodiment.

The unlocking slide 12 has two opposite flanks 12a, the two flanks 12a being provided with respective slide grooves 90, the two slide grooves 90 together defining a locking track. The side wall of the locking slide block 13 is provided with a slide block 13a corresponding to the two side wings 12a one by one, and the slide block 13a is slidably embedded in the chute 90.

The above embodiment provides a possible structure of the locking track, in which the locking slide 13 is stably supported by the structure that two side wings 12a are respectively provided with the sliding grooves 90 to define the locking track, and the locking slide 13 is stably slid back and forth between a distance defined by the locking track, so that the locking slide 13 can be easily and simultaneously driven to slide (by the cooperation between the sliding blocks 13a on the locking slide 13 and the sliding grooves 90) by driving the unlocking unit 17 in an artificial working manner (also can be understood as a working manner in an emergency), so that the locking slide 13 can be smoothly unlocked. Meanwhile, the side wing 12a is small in machining and manufacturing mode difficulty, can be easily realized, and is low in manufacturing cost. It should be noted that, in the embodiment, please refer to fig. 3, two side wings 12a are arranged symmetrically in parallel in fig. 3, wherein two sliding grooves 90 are arranged in a staggered manner, and the sliding distance of the locking sliding block 13 defined by the locking track is smaller than the sliding length of the sliding groove 90 through the staggered arrangement, which has the advantages that the sliding distance of the locking sliding block 13 is defined, and meanwhile, two mutually staggered assembling grooves 91 are formed on the end surfaces of the two side wings 12a, so that the sliding block 13a of the locking sliding block 13 can be easily assembled into the sliding groove 90, thereby reducing the assembling difficulty. In other embodiments, the specific structure of the locking track is not limited, and may be realized by a single-sided chute 90, a common slide rail, or the like, and in other embodiments, the positional relationship between the chute 90 provided on the two side wings 12a is not limited, and the assembly form of the locking slider 13 and the unlocking slider 12 is not limited.

Further, referring back to fig. 2, the driving unit 15 includes a power unit 15a and a gear assembly 15b. The power unit 15a is fixed in the accommodating cavity, and the gear assembly 15b is in transmission connection with the power unit 15 a. The lock slider 13 has a drive rack 13b, and the drive rack 13b is engaged with the gear assembly 15b.

In one possible embodiment, a transmission structure of the driving unit 15 for driving the locking slide 13 to move is provided, and the locking slide 13 is driven to move by a gear transmission manner, so that the electronic lock 10 has a compact, efficient, long-life and precise transmission structure, and meanwhile, the position relationship between the power unit 15a and the locking slide 13 by the gear transmission manner has various choices (such as parallel, vertical, inclined, etc.), so that different position relationships can be selected according to design requirements, and the volume of the electronic lock 10 can be effectively reduced, so that the electronic lock 10 is durable, safe and reliable. Specifically, in this embodiment, the axis of the power output of the power unit 15a and the axis of the locking bolt 14 are perpendicular to each other, and this arrangement is beneficial to the layout of the overall structure of the electronic lock 10, and reduces the volume of the electronic lock 10. In other embodiments, the axis of the power output of power unit 15a and the axis of locking bolt 14 may be parallel or oblique to each other, and in other embodiments, power unit 15a may also be stacked with locking slide 13. It should be noted that, the power unit 15a in the present embodiment may be a motor.

Further, referring to fig. 4, fig. 4 shows a specific structure of the electronic lock 10 in the third view angle in the present embodiment.

The signal feedback unit 18 is fixed in the accommodating cavity, and the signal feedback unit 18 is electrically connected with the driving unit 15; the lock slider 13 has a trigger portion 13c, and when the lock slider 13 moves to a predetermined position with respect to the unlock slider 12, the trigger portion 13c triggers the signal feedback unit 18.

In one possible implementation manner, the electronic lock 10 may implement automatic locking and maintain locking, where the triggering portion 13c may trigger the signal feedback unit 18 when the locking slider 13 reaches a predetermined position (for example, when the locking slider 13 moves to a locked position on the locking slider 13), at this time, the signal feedback unit 18 may feed back the position of the locking slider 13 to the driving unit 15 in an electrical signal manner, and the driving unit 15 may adjust the driving of the locking slider 13 according to the signal. It should be noted that, in the present embodiment, the condition that the triggering portion 13c of the locking slider 13 triggers the signal feedback unit 18 is that the locking slider 13 slides along the sliding slot 90 on the sliding slot 90 to a maximum distance away from the power unit 15a, that is, the locking tongue 14 engaged with the locking slider 13 reaches the maximum locking distance at this time, the signal feedback unit 18 feeds back a signal to the power unit 15a, so that the power unit 15a stops working. In other embodiments, the predetermined position may be another position, for example, when the lock slide 13 slides to the farthest distance position in the direction of the unlock function. Meanwhile, it should be noted that, when the signal feedback unit 18 feeds back the signal to the power unit 15a, the power unit 15a may perform other operations, for example, the power unit 15a may drive the locking slide 13 to move in the opposite direction, etc. It should be noted that, the signal feedback unit 18 in this embodiment is a contact sensor, and the driving unit 15 in this embodiment may be a driving structure including a micro servo motor.

In this embodiment, the conductive element 19 is fixed in the housing 11, and the conductive element 19 has a tuning fork-shaped interface that is laterally inserted with the pins of the signal feedback unit 18 and the driving unit 15, respectively. It should be noted that, in other embodiments, the signal feedback unit 18 and the driving unit 15 may be electrically connected by other structures, for example, directly connected by a wire, or may be connected by a conductive material coated inside the housing 11.

Further, referring to fig. 5, fig. 5 shows a specific structure of the electronic lock 10 in the fourth view angle in the present embodiment.

The housing 11 includes a bottom case 11a and an upper cover 11b, and the upper cover 11b cooperates with the bottom case 11a and forms a receiving cavity together. The bottom case 11a has a slide groove 80, the slide groove 80 defining an unlocking track, and the bottom case 11a has opposite first and second wall surfaces 81 and 82 along an extending direction of the slide groove 80. At least part of locking bolt 14 extends through first wall 81 and part of unlocking unit 17 extends through second wall 82. The return mechanism 16 is configured such that the unlocking slide 12 has a tendency to move toward the first wall surface 81 by an elastic force.

The inner ring of the sealing insert 20 is provided with an annular groove 70, a sealing element 21 is arranged in the annular groove 70, the lock tongue 14 penetrates through the inner ring of the sealing insert 20, and the peripheral wall of the lock tongue 14 is in sealing contact with the sealing element 21.

In one possible embodiment, a structure is provided that enables a tight seal between the locking tongue 14 and the housing 11. In order to achieve high efficiency of manufacture and assembly and control of production cost, the first wall 81 is embedded with the sealing insert 20, that is, the bottom shell 11a is only perforated during manufacture, so that the sealing insert 20 ensures the sealing effect of the lock tongue 14. In particular, the sealing insert 20 is manufactured separately, which, when machined separately, slots its inner ring and enables the sealing element 21 to be provided in this annular groove, thus ensuring the integrity of the sealing surface of the locking tongue 14. Further, the bottom shell 11a is made of plastic, and the difficulty of implementing the annular groove 70 (for providing the sealing element 21) in the mold for manufacturing the bottom shell 11a is high, so that the annular groove 70 is formed by separately machining the sealing insert 20 for reducing the machining difficulty, reducing the manufacturing cost and improving the sealing performance, which is beneficial to the cost control and the smooth performance of the machining and manufacturing, wherein the sealing insert 20 can be a copper insert or other metal or nonmetal insert with stronger hardness. It should be noted that the sealing element 21 may be a tangible part, such as a sealing ring, or may be a structure directly attached to the annular groove 70 by injection molding, spraying, or the like.

Further, the annular groove 70 in the above embodiment has a groove-like structure with closed ends, and the cross section thereof may be circular, elliptical, rectangular, or the like, and may be in a sealed engagement with the tongue 14.

In one possible embodiment, one end of lock tongue 14 engages inside lock slide 13. In other embodiments, locking slide 13 may be rigidly or non-rigidly coupled to locking bolt 14 by other means, such as by bonding, welding, etc., and non-rigidly coupled locking bolt 14 and locking slide 13 may be movably coupled directly, etc.

Meanwhile, it should be explained that in this embodiment, in the normal locking and unlocking process, the unlocking unit 17 does not participate in the action under the action of the reset mechanism 16 (in this embodiment, the reset mechanism 16 is a compression spring, that is, the unlocking unit 17 does not participate in the action under the action of the reset force of the compression spring), that is, the unlocking unit 17 and the electric locking mechanism (the driving unit 15, the unlocking slide block 12 and the locking slide block 13) are independent of each other, that is, operating members (also understood as an operating handle) such as a pull wire 17a of the unlocking unit 17 during normal locking and unlocking cannot rotate, so that the problem of interference of parts in a vehicle body caused by the rotation of the operating handle during electric locking and unlocking is avoided.

Further, the present embodiment also provides another specific structure of the unlocking slide 30 and the locking slide 40.

Please refer to fig. 6 and 7. Fig. 6 shows another specific structure of the unlocking slide 30 and the locking slide 40, and fig. 7 shows a specific structure of the unlocking slide 30 and the locking tongue 14 in the present embodiment.

Wherein the two slide grooves 90a on the flanks 12a of the unlocking slide 30 together define a movement track, a part of which is a locking track. The side wall of the locking slide block 13 is provided with a slide block 13a corresponding to the two side wings 12a one by one, and the slide block 13a is slidably embedded in the chute 90. Specifically, the chute 90a includes two portions, one of which is away from the unlocking unit 17 (or, a portion of this chute 90a is near the lock tongue 14) and the other of which is near the unlocking unit 17 (or, a portion of this chute 90a is far from the lock tongue 14), wherein the chute 90a is stepped up, the drive rack 13b of the lock slider 40 is engaged with the gear assembly 15b when the slider 13a is located at a portion of the chute 90a near the unlocking unit 17, and the drive rack 13b of the lock slider 40 is disengaged from the gear assembly 15b when the slider 13a is located at a portion of the chute 90a far from the unlocking unit 17. Further, referring to fig. 7, as can be seen from fig. 7, the locking slide block 40 is movably connected with the lock tongue 14, and the movement relationship is shown in the figure as a relative up-and-down movement, and the track of the relative movement is consistent with the track of the climbing head and tail of the sliding groove 90a, which has an effect that when the sliding block 13a is located at the portion of the sliding groove 90a near the unlocking unit 17, the sliding block is not pushed by the lock tongue 14 when being pushed forward, however, the unlocking slide block 12 can be dragged by the unlocking unit 17 to realize unlocking. One effect is that when the torque of the power unit 15a is large (when the transmission rack 13b is meshed with the gear assembly 15 b), the forward pushing lock tongue 14 is not pushed, and the reverse manual unlocking can be performed; unlocking can also be performed by pushing lock tongue 14 forward when the torque of power unit 15a is small (when drive rack 13b is engaged with gear assembly 15 b).

Further, the present embodiment also provides a charging socket having the electronic lock 10 provided in any one of the possible implementation manners described above. The charging socket has the electronic lock 10 provided above, so that the charging socket can normally perform locking and unlocking functions when being matched with an external charging gun to ensure the safety of charging, and can directly and manually complete the unlocking function if an emergency occurs.

The above description is only of the preferred embodiments of the present application and is not intended to limit the present application, but various modifications and variations can be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
