Description

Technical Field

[0001] This utility model relates to the technical field of actuators, and in particular to a charging gun lock actuator. Background Technology

[0002] A charging gun is a device used for charging, usually used in conjunction with charging electric vehicles. Charging guns are generally equipped with a switch handle and a locking mechanism to enhance safety during charging.

[0003] Currently, the locking methods for DC and AC charging ports of new energy vehicles are basically separate. For example, the charging gun has an internal lock, which completes the DC locking; the AC charging socket has a charging lock actuator, which completes the AC locking. Locking the DC and AC charging ports separately through the charging gun and the body charging socket actuator has lower reliability and increases costs.

[0004] In view of this, this utility model is developed by deeply conceiving and actively researching, improving and testing the design of existing charging gun lock structures to address the many shortcomings and inconveniences caused by their imperfections. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a dual-purpose charging gun lock actuator that can lock both DC and AC charging ports simultaneously, thus saving resource costs.

[0006] To achieve the above objectives, the solution of this utility model is:

[0007] A charging gun lock actuator, characterized in that: it includes a housing, an output shaft, an output gear, a first charging lock assembly, and a second charging lock assembly, wherein the output gear is disposed inside the housing, the output shaft is rotatably mounted on the housing, and the output shaft is connected to and linked with the output gear;

[0008] The first charging lock assembly includes a transmission base and a first charging port locking rod. The first charging port locking rod passes through the housing and is connected to the transmission base. The transmission base is movably installed inside the housing, and the inner wall of the transmission base is provided with a first rack that meshes with the output gear, and the outer wall of the transmission base is provided with a second rack.

[0009] The second charging lock assembly includes a transmission block and a second charging port locking rod. The transmission block is provided with locking teeth that mesh with the second rack, and the second charging port locking rod is connected to the transmission block and extends movably out of the housing.

[0012] Furthermore, the surface of the output shaft and the inner wall of the shaft hole of the output gear are respectively provided with a connecting block and a connecting groove that cooperate with each other. The connecting block and the connecting groove are engaged with each other to connect the output shaft and the output gear.

[0013] Furthermore, the housing includes an upper shell and a lower shell that interlock with each other, the output shaft is rotatably mounted on the upper shell, and the first charging lock assembly and the second charging lock assembly are both mounted on the lower shell.

[0014] Furthermore, the lower shell sidewall is provided with a first through hole corresponding to the first charging port locking rod, and the first charging port locking rod is movably fitted into the first through hole.

[0018] Furthermore, an emergency unlocking part is provided at the end of the output shaft away from the output gear, and the emergency unlocking part is disposed through the housing.

[0019] With the above structure, this utility model converts the rotation of the output shaft into the extension and retraction of the first charging port locking rod. The transmission block is rotated by the transmission seat, thereby driving the extension and retraction of the second charging port locking rod. The actuator on the charging seat performs the locking action of the AC charging port and the DC charging port. Compared with the separate locking method, the cost is reduced and more economical.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below.

[0031] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0032] like Figures 1 to 8As shown, this is a preferred embodiment of a charging gun lock actuator of the present invention, including a housing 1, an output shaft 2, an output gear 3, a first charging lock assembly, and a second charging lock assembly. The output gear 3 is disposed inside the housing 1, and the output shaft 2 is rotatably mounted on the housing 1, and the output shaft 2 is connected to and linked with the output gear 3. The first charging lock assembly includes a transmission seat 4 and a first charging port locking rod 5. The first charging port locking rod 5 passes through the housing 1 and is connected to the transmission seat 4. The transmission seat 4 is movably mounted inside the housing 1, and the inner wall of the transmission seat 4 is provided with a first rack 41 that meshes with the output gear 3, and the outer wall of the transmission seat 4 is provided with a second rack 42. The second charging lock assembly includes a transmission block 6 and a second charging port locking rod 8. The transmission block 6 is provided with a locking tooth 61 that meshes with the second rack 42, and the second charging port locking rod 8 is connected to the transmission block 6 and movably extends out of the housing 1.

[0033] Specifically, the output shaft 2 is used to drive the output gear 3 to rotate, thereby driving the first charging lock assembly and the second charging lock assembly to move. The output shaft 2 can be driven to rotate by a motor, a motor and gear set, etc., which is not limited here.

[0034] In this embodiment, the actuator is installed on the AC charging dock. The first charging lock component is a DC charging lock component, used to lock the DC charging dock charging port b. The second charging lock component is an AC charging lock component, used to lock the AC charging dock charging port a.

[0035] In other embodiments, the actuator may be mounted on the DC charging dock, and the AC charging dock charging port a may be locked by the first charging lock assembly, and the DC charging dock charging port b may be locked by the second charging lock assembly.

[0036] During the unlocking process, the output shaft 2 rotates, driving the output gear 3 to rotate. Through the meshing of the output gear 3 with the first rack 41, the transmission seat 4 is driven to retract inward. The transmission seat 4 drives the first charging port locking rod 5 to retract and unlock. At the same time, through the meshing of the second rack 42 with the locking tooth 61, the transmission block 6 is driven to rotate, thereby driving the second charging port locking rod 8 to retract and unlock.

[0037] During the locking process, the output shaft 2 rotates, driving the output gear 3 to rotate. Through the meshing of the output gear 3 with the first rack 41, the transmission seat 4 extends outward. The transmission seat 4 drives the first charging port locking rod 5 to extend and lock. At the same time, through the meshing of the second rack 42 with the locking tooth 61, the transmission block 6 rotates, thereby driving the second charging port locking rod 8 to extend and lock.

[0038] That is, when the first charging port locking lever 5 is extended, it locks and when it is retracted, it unlocks the DC charging port b; when the second charging port locking lever 8 is extended, it locks and when it is retracted, it unlocks the AC charging port a.

[0039] The key feature of this invention is that it converts the rotation of the output shaft 2 into the extension and retraction of the first charging port locking rod 5. The transmission block 6 is rotated by the transmission seat 4, thereby driving the extension and retraction of the second charging port locking rod 8. The actuator on the charging seat performs the locking action of the AC charging port a and the DC charging port b. Compared with the separate locking method, this reduces costs and is more economical.

[0040] Furthermore, the structure of this utility model eliminates the internal lock of the charging gun, allowing the charging gun to be designed in a more compact and versatile style.

[0041] In this embodiment, the housing 1 includes an upper housing 11 and a lower housing 12 that are interlocked. The output shaft 2 is rotatably mounted on the upper housing 11, and the first charging lock assembly and the second charging lock assembly are both mounted on the lower housing 12.

[0042] In this embodiment, the transmission block 6 is rotatably mounted on the lower shell 12. The transmission block 6 is provided with a hinge part 62 for driving the first charging port locking rod 5, which converts the rotational motion of the transmission block 6 into the linear motion of the first charging port locking rod 5.

[0043] In this embodiment, the second charging lock assembly further includes a drive rod 7, with both ends of the drive rod 7 hinged to the hinge portion 62 and the second charging port lock rod 8, respectively.

[0044] The rotational motion of the transmission block 6 is transmitted to the drive rod 7 via the hinge 62, and then to the second charging port locking rod 8 via the drive rod 7, thereby causing the second charging port locking rod 8 to move linearly. In other embodiments, the drive rod 7 and the second charging port locking rod 8 can also be a single component.

[0045] The surface of the output shaft 2 and the inner wall of the shaft hole of the output gear 3 are respectively provided with a connecting block 21 and a connecting groove 31 that cooperate with each other. The connecting block 21 and the connecting groove 31 are engaged with each other to connect the output shaft 2 and the output gear 3.

[0046] In this embodiment, a connecting block 21 is provided at one end of the output shaft 2 near the output gear 3, and a connecting groove 31 is provided on the inner wall of the shaft hole of the output gear 3. In other embodiments, the connecting block 21 may be provided on the output gear 3, and the connecting groove 31 may be provided on the output shaft 2; no specific limitation is made here.

[0047] After the connecting block 21 and the connecting slot 31 are engaged with each other, the output shaft 2 and the output gear 3 rotate coaxially, and the rotational motion of the output shaft 2 can be stably transmitted to the output gear 3.

[0048] In this embodiment, the side wall of the lower shell 12 is provided with a first through hole 121 corresponding to the first charging port locking rod 5, and the first charging port locking rod 5 is movably fitted in the first through hole 121.

[0049] The aforementioned transmission seat 4 is provided with a mounting part 43 at the corresponding first through hole 121, and the first charging port locking rod 5 is mounted on the mounting part 43.

[0050] During the locking process, the mounting part 43 approaches the first through hole 121 under the push of the drive gear, thereby causing the first charging port locking rod 5 to extend and lock; during the unlocking process, the mounting part 43 moves away from the first through hole 121, thereby causing the first charging port locking rod 5 to retract and unlock.

[0051] In this embodiment, the side wall of the lower shell 12 is provided with a second through hole 122 at the corresponding second charging lock assembly, and the second charging port locking rod 8 is disposed through the second through hole 122.

[0052] During the locking process, the drive rod 7 approaches the second through hole 122 under the push of the hinge part 62, thereby causing the second charging port locking rod 8 to extend and lock; during the unlocking process, the drive rod 7 moves away from the second through hole 122, thereby causing the second charging port locking rod 8 to retract and unlock.

[0053] In this embodiment, a sleeve 123 is formed protruding from the side wall of the lower shell 12 at the second through hole 122, and the second charging port locking rod 8 is movably fitted inside the sleeve 123. During the locking / unlocking process, the second charging port locking rod 8 reciprocates linearly along the sleeve 123, and is limited and guided by the sleeve 123, making the structure more stable.

[0054] In this embodiment, an emergency unlocking part 22 is provided at the end of the output shaft 2 away from the output gear 3, and the emergency unlocking part 22 is disposed through the housing 1.

[0055] Specifically, the emergency unlocking part 22 passes through the upper shell 11 and is exposed outside the actuator. When emergency unlocking is required, rotating the emergency unlocking part 22 will manually rotate the output shaft 2, which will drive the transmission seat 4 to retract and the transmission block 6 to rotate through the output gear 3, thereby causing the first charging port locking rod 5 and the second charging port locking rod 8 to retract, thus achieving the purpose of unlocking.

[0056] This specification uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
