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 includes a housing, an output motor, a gear set, a first charging lock assembly, and a second charging lock assembly. The output motor, gear set, and first charging lock assembly are all disposed within the housing, and the second charging lock assembly is installed within the housing.

[0008] The output shaft of the output motor is provided with a motor gear, and the gear set meshes with the motor gear.

[0009] The first charging lock assembly includes a first charging port locking rod, the first end of which extends movably out of the housing, the middle part of which is provided with a rack that meshes with the gear set, and the end of which is provided with a protrusion.

[0010] The second charging lock assembly includes a linkage, a cam, and a second charging port locking rod. The linkage is rotatably disposed within the housing and movably connected to the protrusion. The cam is mounted on the linkage, and the second charging port locking rod is movably mounted on the cam.

[0011] Furthermore, the linkage is provided with a pawl for pushing the protrusion, and the linkage extends upward at its rotation axis to form a connecting rod. The cam is sleeved on the connecting rod, and the cam rotates coaxially with the linkage.

[0012] Furthermore, the gear set includes multiple double gears, with the larger gear in the double gear closest to the output motor meshing with the motor gear, and then adjacent double gears meshing with each other in sequence through a small gear and a large gear; the rack meshes with the small gear in the adjacent double gear.

[0013] Furthermore, the connecting rod passes through the housing and connects to the cam, and both the second charging port locking rod and the cam are located outside the housing.

[0014] Furthermore, the top of the connecting rod extends out of the housing and is equipped with an emergency unlocking element, which rotates synchronously with the linkage component.

[0015] Furthermore, it also includes a second locking rod housing installed in the housing. The second locking rod housing includes a lower cover and an upper cover that are interlocked with each other. The cam is rotatably engaged between the lower cover and the upper cover. A guide groove is formed at the connection between the lower cover and the upper cover. The second charging port locking rod is movably engaged in the guide groove.

[0016] Furthermore, the cam is provided with a track groove, and the end of the second charging port locking rod is movably fitted within the track groove.

[0017] Furthermore, a micro switch is provided inside the housing, and the micro switch has a telescopic trigger rod; a contact part is provided on the side of the second charging port locking rod, and the trigger rod makes movable contact with the contact part.

[0018] Furthermore, the side wall of the housing is provided with a first through hole, and the first charging lock assembly also includes a first sealing ring and a sealing ring cover. The first sealing ring is sealed and fitted in the first through hole, the first charging port lock rod is inserted in the first sealing ring and makes movable sealing contact with the first sealing ring, and the sealing ring cover covers the first through hole.

[0019] Furthermore, the top of the housing is provided with a second through hole, and a second sealing ring is fitted on the connecting rod. The connecting rod passes through the second through hole and the second sealing ring is sealed and fitted inside the second through hole.

[0020] With the above structure, this utility model converts the rotation of the output motor into the extension and retraction of the first charging port locking rod through the gear set. The protrusion on the first charging port locking rod drives the linkage and cam to rotate, thereby driving the extension and retraction of the second charging port locking rod. The actuator on the charging base performs the locking action of the AC charging base charging port and the DC charging base charging port. Compared with the separate locking method, the cost is reduced and more economical.

[0021] 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. Attached Figure Description

Detailed Implementation

[0031] 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.

[0032] 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.

[0033] like Figures 1 to 8 As shown, this is a preferred embodiment of a charging gun lock actuator of the present invention, including a housing 1, an output motor 2, a gear set 3, a first charging lock assembly 4, and a second charging lock assembly 5. The output motor 2, the gear set 3, and the first charging lock assembly 4 are all disposed within the housing 1, and the second charging lock assembly 5 is installed on the housing 1. A motor gear 21 is provided on the output shaft of the output motor 2, and the gear set 3 meshes with the motor gear 21. The first charging lock assembly 4 includes a first charging port locking rod 41, the head of which extends movably out of the housing 1. A rack 42 that meshes with the gear set 3 is provided in the middle of the first charging port locking rod 41, and a protrusion 43 is provided at the end of the first charging port locking rod 41. The second charging lock assembly 5 includes a linkage member 51, a cam 52, and a second charging port locking rod 54. The linkage member 51 is rotatably disposed within the housing 1 and movably connected to the protrusion 43. The cam 52 is installed on the linkage member 51, and the second charging port locking rod 54 is movably installed on the cam 52.

[0034] Specifically, the gear set 3 includes multiple double gears 31. The larger gear in the double gear 31 closest to the output motor 2 meshes with the motor gear 21. Then, adjacent double gears 31 mesh with each other in sequence through the small gear and the large gear. The rack 42 meshes with the small gear in the adjacent double gear 31.

[0035] In this embodiment, the actuator is installed on the AC charging dock. The first charging lock component 4 is an AC charging lock component used to lock the AC charging dock charging port a. The second charging lock component 5 is a DC charging lock component used to lock the DC charging dock charging port b.

[0036] In other embodiments, the actuator can also be mounted on a DC charging dock, and the charging port b of the DC charging dock can be locked by the first charging lock assembly 4, and the charging port a of the AC charging dock can be locked by the second charging lock assembly 5.

[0037] During operation, the output motor 2 drives multiple double gears 31 in the gear set 3 to rotate sequentially through the motor gear 21 until the last double gear 31 drives the first charging port locking rod 41 to extend and retract through the rack 42, thereby achieving the purpose of locking when the first charging port locking rod 41 extends and unlocking the AC charging port a when it retracts; at the same time, the protrusion 43 at the end of the first charging port locking rod 41 drives the linkage 51 to rotate, the linkage 51 drives the cam 52 to rotate, and the cam 52 drives the second charging port locking rod 54 to extend and retract, thereby achieving the purpose of locking when the second charging port locking rod 54 extends and unlocking the DC charging port b when it retracts.

[0038] It should be noted that the number of double gears 31 in gear set 3 can be defined according to the specific output force value. At the same time, the number of double gears 31 must ensure that the motor gear 21 can mesh with the rack 42 through gear set 3, and meet the travel of the locking rod extension and retraction. In this embodiment, gear set 3 includes three double gears 31.

[0039] The key feature of this invention is that it converts the rotation of the output motor 2 into the extension and retraction of the first charging port locking rod 41 through the gear set 3. The protrusion 43 on the first charging port locking rod 41 drives the linkage 51 and the cam 52 to rotate, thereby driving the extension and retraction of the second charging port locking rod 54. The actuator on the charging base 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 linkage 51 is provided with a pawl 511 for pushing the protrusion 43. The linkage 51 extends upward at its rotation axis to form a connecting rod 512. The cam 52 is sleeved on the connecting rod 512, and the cam 52 rotates coaxially with the linkage 51.

[0042] Specifically, the linkage 51 is located on the side of the first charging port locking rod 41, and the claw 511 abuts against the front and rear sides of the protrusion 43. The protrusion 43 is connected to the claw 511 during the forward and backward movement, so that the first charging port locking rod 41 and the second charging port locking rod 54 can move stably and synchronously.

[0043] In this embodiment, the connecting rod 512 passes through the housing 1 and is connected to the cam 52. The second charging port locking rod 54 and the cam 52 are both located outside the housing 1.

[0044] Specifically, the housing 1 includes a housing body 11 and a housing cover 12 that are interlocked. The connecting rod 512 passes through the housing cover 12 and extends out of the housing 1. An emergency unlocking element 8 is provided at the top of the connecting rod 512. The emergency unlocking element 8 rotates synchronously with the linkage 51. When emergency unlocking is required, rotating the emergency unlocking element 8 drives the linkage 51 to rotate. The linkage 51 then drives the protrusion 43 to retract and the cam 52 to rotate, causing the first charging port locking rod 41 and the second charging port locking rod 54 to retract, thus achieving the purpose of unlocking.

[0045] In this embodiment, a second locking rod box 6 is installed on the housing 1. The second locking rod box 6 includes a lower box cover 61 and a upper box cover 62 that are interlocked with each other. A cam 52 is rotatably engaged between the lower box cover 61 and the upper box cover 62. A guide groove 63 is formed at the connection between the lower box cover 61 and the upper box cover 62. The second charging port locking rod 54 is movably engaged in the guide groove 63.

[0046] Both the upper cover 62 and the lower cover 61 of the box have through holes through which the arched connecting rod 512 passes. The connecting rod 512 passes through the shell cover 12, the lower cover 61, and the upper cover 62 in sequence before connecting to the emergency unlocking element 8. The lower cover 61 is fixed to the shell cover 12, and the upper cover 62 covers the cam 52. The cam guides the second charging port locking rod 54 through the guide groove 63, helping to convert the rotational motion of the cam 52 into the linear movement of the second charging port locking rod 54.

[0047] In this embodiment, the cam 52 is provided with a track groove 53, and the end of the second charging port locking rod 54 is movably fitted in the track groove 53.

[0048] The lowest point of the track groove 53 is located near the rotation axis of the cam 52, while the highest point is located away from the rotation axis of the cam 52. During the rotation of the cam 52, the second charging port locking rod 54 slides back and forth within the track groove 53.

[0049] When the first charging port locking rod 41 retracts, the cam 52 rotates, causing the second charging port locking rod 54 to move to the low point of the rotating groove, i.e., the second charging port locking rod 54 retracts; when the first charging port locking rod 41 extends, the cam 52 rotates, causing the second charging port locking rod 54 to move to the high point of the rotating groove, i.e., the second charging port locking rod 54 extends.

[0050] In this embodiment, a micro switch 7 is provided inside the housing 1, and the micro switch 7 is provided with a telescopic trigger rod 71; a contact part 44 is provided on the side of the first charging port locking rod 41, and the trigger rod 71 is in active contact with the contact part 44.

[0051] Specifically, the contact surfaces of the contact portion 44 and the trigger rod 71 are inclined, and the top of the trigger rod 71 can slide along the inclined surface of the contact portion 44 to determine position information.

[0052] In this embodiment, the side wall of the housing body 11 is provided with a first through hole 111, and the first charging lock assembly 4 also includes a first sealing ring 45 and a sealing ring cover 46. The first sealing ring 45 is sealed and fitted in the first through hole 111, the first charging port locking rod 41 is inserted into the first sealing ring 45 and is in movable sealing contact with the first sealing ring 45, and the sealing ring cover 46 covers the first through hole 111.

[0053] In this embodiment, the top of the cover 12 is provided with a second through hole 121, and a second sealing ring 55 is fitted on the connecting rod 512. The connecting rod 512 passes through the second through hole 121 and the second sealing ring 55 is sealed and fitted inside the second through hole 121.

[0054] By setting the first sealing ring 45 and the second sealing ring 55, dust, moisture, etc. can be prevented from entering the actuator and causing malfunctions.

[0055] 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.
