Description
Technical Field
[0001] This utility model relates to the field of locking technology for charging guns, and in particular to an electronic lock. Background Technology
[0002] The vehicle charging gun is equipped with an electronic lock driven by both mechanical and electronic means. In slow charging mode, the mechanical button can be released from its fixed position by pushing or pressing, allowing the charging gun to be pulled out smoothly. However, when the vehicle is locked, the electronic lock of the charging gun automatically extends and locks the charging gun in place. In this case, the charging gun can only be pulled out by unlocking the vehicle and retracting the electronic lock.
[0003] However, existing electronic locks (refer to the instruction manual) Figure 5 As shown, the electronic lock has two switches, which prevents the wires from going straight out and the outer shell from being molded. It can only maintain the method and shape of using two covers, which leads to the high cost of the electronic lock and also prevents the shape of the electronic lock from being further reduced, requiring a large space.
[0004] Therefore, this utility model proposes an electronic lock. Utility Model Content

[0020] Preferably, the locking structure further includes:
[0021] The push rod has an end that protrudes from the locking structure, and there is an angle between the push rod and the locking tongue.
[0022] Pushing the push rod causes the engaging end to move toward the second limiting member, and the push rod gradually enters the covering surface of the housing, while the locking tongue gradually protrudes from the covering surface of the housing.
[0023] Preferably, it further includes:
[0024] A reset structure is built into the housing and partially protrudes from the top of the housing; the protruding end of the reset structure coincides with the locked state of the locking structure; the reset structure compresses its own height and tends to return to its original shape when the locking structure is locked.
[0025] When the drive structure receives an external charging stop signal through the terminal, the drive structure is powered off, and the reset structure pushes the locking structure to return to its original state.
[0026] Preferably, the reset structure includes:
[0027] The switch body is built into the housing and is arranged parallel to the drive structure;
[0028] The pressure element has an inclined strip-shaped structure; one end of the pressure element is fixed to the edge of the switch body, and the other end is suspended above the symmetrical edge of the switch body; the other end of the pressure element protrudes from the housing and is pressed towards the switch body by the locking structure in the locked state.
[0029] Preferably, the switch body includes:
[0030] The rebound button is protruding from the edge of the upper end face of the switch body and is located on the same vertical line as the other end of the pressure member;

Its size is small and it is suitable for confined spaces.
[0035] Second, the drive structure of the electronic lock proposed in this utility model is provided with a drive end that is mutually non-empty with the through hole of the locking structure, so that the drive structure can accurately and timely control the rotation of the locking structure through the drive end.
[0036] Third, the electronic lock proposed in this utility model, through the reset structure and the switch body set in cooperation with the reset structure, can realize the power storage of the reset structure and the recording of the current electronic lock state by the switch body in the locked state.

[0037] Fourth, the electronic lock reset structure proposed in this utility model is achieved by using an inclined pressure member. After the locking structure loses the power of the driving structure, the locking structure slides down along the inclined surface of the pressure member due to its own rebound tendency, restoring the original position of the locking structure, reducing the power output for restoring the original state of the locking structure, and achieving energy saving effect.

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0045] Existing electronic locks have two switches, which prevents the wires from being routed out directly and the outer casing from being demolded. This forces the use of two separate covers to maintain the original shape and cost of the electronic locks. It also limits the size of the electronic locks and results in a large space requirement.
[0046] like Figures 1-4 As shown, to solve the above problems, this embodiment proposes an electronic lock, including a housing 10, a locking structure 20, and a driving structure 30. The housing 10 is an integrally formed structure. The locking structure 20 is disposed on the upper end surface of the housing 10. The driving structure 30 is built into the housing 10, and the driving end 31 of the driving structure 30 controls the rotation of the locking structure 20. A terminal 32 is formed on the end of the driving structure 30 symmetrical to the driving end 31, and the terminal 32 protrudes from the housing 10. In this embodiment, when the driving structure 30 receives an external charging signal through the terminal 32, the driving structure 30 drives and controls the locking structure 20 to rotate and adjust it to the locked state.
[0047] Preferably, in this embodiment, the driving end 31 of the driving structure 30 and the locking structure 20 rotate synchronously, or the transmission rotation can be achieved by meshing connection or other means.
[0048] Preferably, in this embodiment, the drive structure 30 is a motor, and the drive end 31 is a rotating shaft that extends out of the motor and penetrates the upper surface of the housing 10.
[0049] In this embodiment, since the wiring terminal 32 of the drive structure 30 is symmetrically arranged with the drive end 31, that is, the electronic lock as a whole has a structure with straight wires, its wiring terminal 32 will not affect the mold demolding, and the design of the housing 10 can be integrated, which can reduce the number of parts and costs, and at the same time reduce the volume of the finished product, making it suitable for small spaces.
[0050] More specifically, the locking structure 20 includes a limiting hole 21 and a locking tongue (not shown in the attached figure, but located in part A of the figure); the limiting hole 21 is a through hole that runs longitudinally through the locking structure 20; the driving end 31 of the driving structure 30 and the limiting hole 21 are mutually exempted; the locking tongue is located on the edge of the locking structure 20 and protrudes from the housing 10 as the locking structure 20 rotates.
[0051] Preferably, in this embodiment, the cross-section of the limiting hole 21 is a near-circular shape with a straight line cut out; the free end of the driving end 31 is also a near-cylindrical structure with a rectangular plane cut out, and the height of the rectangular plane on the limiting member is equal to the thickness of the locking structure 20. Preferably, but not limited to, the free end of the driving end 31 in this embodiment can also be of other shapes, as long as it is ensured that the driving end 31 and the limiting hole 21 are mutually non-displaced and their shapes cannot rotate relative to each other.
[0052] Preferably, in this embodiment, the center of the limiting hole 21 is set to coincide with the center of gravity of the locking structure 20, so that the driving end 31 of the driving structure 30 can easily drive the rotation of the locking structure 20.
[0053] Preferably, the shape of the locking tongue is not limited in this embodiment, and can be adapted to different application environments of the electronic lock.
[0054] In this embodiment, the limiting hole 21 and the driving end 31, which are mutually designed to avoid each other, ensure that after the driving structure 30 receives the charging signal, the driving end 31 can effectively control the rotation of the locking structure 20, thus ensuring the timeliness of the electronic lock and preventing the electronic lock from automatically disengaging from the locked state.
[0055] More specifically, it also includes a first limiting member 11 and a second limiting member 12 disposed on the upper end face of the housing 10; the first limiting member 11 and the second limiting member 12 are both located on the rotation path of the locking structure 20, and the first limiting member 11 and the second limiting member 12 limit the rotation range of the locking structure 20.
[0056] Preferably, in this embodiment, the first limiting member 11 and the second limiting member 12 are disposed on the edge of the upper end surface of the housing 10. While ensuring that the first limiting member 11 and the second limiting member 12 limit the rotation range of the locking structure 20, the area of the upper end surface of the housing 10 is reduced, thus ensuring the compactness of the finished electronic lock.
[0057] Preferably, in this embodiment, the first limiting member 11 and the second limiting member 12 are block structures, which increases the blocking force of the first limiting member 11 and the second limiting member 12 on the locking structure 20, and avoids the possibility that the first limiting member 11 and the second limiting member 12 will be damaged by excessive rotational force under the drive of the drive structure 30, causing the locking structure 20 to rotate out of range.
[0058] Preferably, in this embodiment, the first limiting member 11 and the second limiting member 12 have the same height, and the height can be the same as the thickness of the locking structure 20.
[0059] In this embodiment, the first limiting member 11 and the second limiting member 12 effectively limit the rotation range of the locking structure 20. The positions of the first limiting member 11 and the second limiting member 12 are set according to the specific shape and stroke of the locking structure 20.
[0060] More specifically, the locking structure 20 includes a locking end 22 protruding from the side of the locking structure 20; the first limiting member 11 and the second limiting member 12 are disposed on the movement path of the locking end 22, and the locking end 22 is disposed on the arc line of the first limiting member 11 and the second limiting member 12 as the two ends.
[0061] Preferably, in this embodiment, the locking tongue and the engaging end 22 of the locking structure 20 should be located on opposite sides of the locking structure 20 to avoid the need for a larger housing 10 due to the large area of the locking structure 20.
[0062] Preferably, in this embodiment, the end faces of the engaging end 22 that contact the first limiting member 11 and the second limiting member 12 respectively are planes, and the opposing end faces of the first limiting member 11 and the second limiting member 12 are planes. That is, the contact and collision between the engaging end 22 and the first limiting member 11 and the second limiting member 12 are all planar contacts, which ensures that the locking structure 20 will not shake after colliding with the first limiting member 11 and the second limiting member 12, thus ensuring the stability of the electronic lock in the locking and unlocking states.
[0063] In this embodiment, the rotation range of the locking structure 20 is limited by the contact between the outwardly extending engaging end 22 and the first limiting member 11 and the second limiting member 12, thus ensuring the rotation stroke of the locking structure 20.
[0064] More specifically, the locking structure 20 also includes a push rod 23 protruding from its end, and the push rod 23 forms an angle with the locking tongue. In this embodiment, when the push rod 23 is pushed, the engaging end 22 moves toward the second limiting member 12, the push rod 23 gradually enters the covering surface of the housing 10, and the locking tongue gradually protrudes from the covering surface of the housing 10.
[0065] Preferably, in this embodiment, the push rod 23 is stacked on the upper end face of the locking structure 20, and a limiting hole 21 is formed on the push rod 23. Preferably, but not limited to, the push rod 23 and the locking structure 20 are integrally formed.
[0066] Preferably, in this embodiment, the protruding end of the push rod 23 and the locking tongue are located on the same side of the locking structure 20.
[0067] In this embodiment, the push rod 23 protrudes from the housing 10 in the locked state. The user can push the push rod 23 to retract the bolt and realize the mechanical unlocking state of the electronic lock. However, since the drive structure 30 still has a drive signal, if the applied force on the push rod 23 is removed, the electronic lock will still be in the locked state.
[0068] More specifically, it also includes a reset structure 40 built into the housing 10, with a portion of the reset structure 40 protruding from the top of the housing 10; the protruding end of the reset structure 40 coincides with the locked state of the locking structure 20; the reset structure 40 compresses its own height and tends to return to its original state when the locking structure 20 is locked. In this embodiment, when the drive structure 30 receives an external charging stop signal through the terminal 32, the drive structure 30 is de-energized, and the reset structure 40 pushes the locking structure 20 to return to its original state.
[0069] Preferably, the locking structure 20 is disposed close to the upper end face of the housing 10. Therefore, in the locked state, the locking structure 20 compresses the reset structure 40, causing the reset structure 40 to be completely inside the housing 10.
[0070] More specifically, the reset structure 40 includes a switch body 41 and a pressure member 42; the switch body 41 is built into the housing 10 and is arranged parallel to the drive structure 30; the pressure member 42 has an inclined strip structure; one end of the pressure member 42 is pivotally connected to the edge of the switch body 41, and the other end is suspended above the symmetrical edge of the switch body 41; the other end of the pressure member 42 protrudes from the housing 10 and is pressed towards the switch body 41 by the locking structure 20 in the locked state.
[0071] Preferably, the pressure member 42 is distributed in three sections, with the middle section having the steepest slope. Preferably, but not limited to, the connection point of the three sections is a smooth connection, and the slope near the pivot end is hollowed out to facilitate slight deformation of the pressure member 42.
[0072] Preferably, in this embodiment, the upper end face of the housing 10 is provided with a strip-shaped hole for the pressure member 42 to be fully exposed, which facilitates the structural accommodation of the pressure member 42 in the pressure state and the springback state.
[0073] In this embodiment, one end of the pressure member 42 is pivotally connected to the edge of the switch body 41. When the free end of the pressure member 42 is pressed down, the pressure member 42 will generate a rebound force with the pivot end as the origin. When the locking structure 20 loses the drive of the drive structure 30, the locking structure 20 will rotate along the inclined surface of the pressure member 42 and return to its original position. At this time, the locking tongue of the locking structure 20 retracts.
[0074] More specifically, a spring-loaded button 43 is also provided with a protrusion on the upper edge of the switch body 41, and the spring-loaded button 43 is located on the same vertical line as the other end of the pressure member 42. In this embodiment, when the locking structure 20 enters the locked state, the pressure member 42 presses down to squeeze the spring-loaded button 43, and the switch body 41 displays the locked state; when the drive structure 30 loses the external charging signal, the reset structure 40 pushes the locking structure 20 back to its original state, the spring-loaded button 43 resets, and the switch body 41 displays the unlocked state.
[0075] Preferably, in this embodiment, the switch body 41 serves as a feedback switch. When the push-back button 43 is pressed down, it records and outputs a data signal indicating that the electronic lock is currently in the locked state. When the push-back button 43 is reset, the switch body 41 records and outputs a data signal indicating that the electronic lock is currently in the unlocked state.
[0076] Preferably, in this embodiment, the bottom end of the switch body 41 is also provided with a terminal 32, which can be connected to a corresponding control system and output the recorded data signal.
[0077] In this embodiment, the setting of the switch body 41 and the rebound button 43 thereon can effectively ensure that the recorded data of the switch body 41 is consistent with the state of the electronic lock, so as to keep the control circuit of the electronic lock consistent.
[0078] More specifically, the outer surface of the housing 10 is also formed with ear seats 13. Preferably, there are four ear seats 13, which are symmetrically distributed in pairs.
[0079] In this embodiment, the locking principle of the electronic lock is as follows: When the charging gun or other product is inserted into the electric vehicle charging interface and a charging start signal is issued, the control circuit energizes the electromagnetic coil in the drive structure 30, generating a magnetic field that attracts the locking mechanism to move, causing the locking tongue to engage with the corresponding position of the charging interface to achieve locking. Simultaneously, the action of the locking mechanism triggers the switch body 41 through the reset structure 40, changing its state. The corresponding unlocking principle is as follows: When charging is finished or the charging gun needs to be removed early, the control circuit receives an unlocking signal, stops supplying power to the electromagnetic coil in the drive structure 30, the magnetic field disappears, and the locking mechanism returns to its initial position under the action of the reset structure 40. The locking tongue retracts to achieve unlocking, and the switch body 41 also resets to its initial state.
[0080] The switch body 41 is connected to the control circuit of the charging gun. By monitoring changes in the switch state, the control circuit can obtain the status information of the electronic lock in real time. When the rebound button 43 is closed, the control circuit knows that the charging gun has been successfully locked and can continue the charging operation; when the rebound button 43 is open, the control circuit determines that the charging gun has been unlocked and can perform corresponding subsequent processing, such as stopping charging-related communications. This ensures the safety and reliability of the charging process and prevents the charging gun from accidentally falling off or being forcibly pulled out before unlocking.
[0081] In summary, this embodiment proposes an electronic lock that, by reducing the number of switches inside the electronic lock and adjusting the direct wiring method, achieves a compact overall design suitable for confined spaces; at the same time, it allows for easy demolding of the housing, resulting in a one-piece molding design and reducing manufacturing costs.
[0082] The embodiments described above do not constitute a limitation on the scope of protection of this technical solution. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the above embodiments should be included within the scope of protection of this technical solution.
