Description

Technical Field

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

[0002] Currently, the locking methods used for DC charging and AC charging of new energy vehicles are basically independent. DC-charging vehicles have their locking function located on the charging gun (i.e., the charging gun has a built-in lock), while AC-charging vehicles rely on the actuator of the charging dock. In fact, if the charging gun or the charging dock actuator had the ability to lock both DC and AC charging ports simultaneously, one actuator could be eliminated. This would offer significant advantages in terms of cost control, resource utilization, and reliability. From a cost perspective, reducing an actuator directly lowers hardware procurement and maintenance costs; in terms of resource utilization, it simplifies the system structure and optimizes space layout; and in terms of reliability, reducing an actuator means reducing a potential point of failure, thereby improving the stability of the entire charging locking system.

[0003] In response to the aforementioned problems existing in the separate locking of DC charging ports and AC charging ports of current new energy vehicles, the inventor conducted in-depth research and exploration, which led to the creation of this invention. Utility Model Content

[0004] 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, thereby reducing costs, simplifying the system structure, and improving charging stability.

[0005] To achieve the above objectives, the solution of this utility model is:

[0006] A dual-purpose charging gun lock actuator, comprising:

[0007] The outer casing is equipped with an AC lock lever port and a DC lock lever port.

[0008] The motor is housed within a casing and has an output shaft.

[0009] A gear transmission mechanism is housed inside the casing and is connected to the output shaft of the motor.

[0010] A rack is movably mounted inside the housing and meshes with a gear transmission mechanism.

[0011] The first charging port locking rod is set on the AC locking rod opening of the outer casing. One end of the first charging port locking rod is connected to the rack, and the other end protrudes out of the outer casing.

[0012] A transmission component, which is housed within a housing, has an output gear that meshes with a gear transmission mechanism;

[0013] The second charging port locking rod is located on the DC locking rod opening of the outer casing. One end of the second charging port locking rod is connected to the transmission component by a screw drive, and the other end protrudes out of the outer casing.

[0014] Furthermore, the outer casing includes a housing and a cover, with the AC locking lever port and DC locking lever port correspondingly arranged on two adjacent sides of the housing, and a micro switch for determining the position information of the rack is also provided inside the housing.

[0015] Furthermore, the output shaft of the motor has a screw structure, and the gear transmission mechanism has a helical gear that meshes with the screw.

[0016] Furthermore, a drive gear is fixedly mounted on the output shaft of the motor, and the gear transmission mechanism meshes with the drive gear.

[0017] Furthermore, the gear transmission mechanism includes a first transmission gear, a second transmission gear, and a third transmission gear, each having two gears. The first transmission gear meshes with the output shaft of the motor and the second transmission gear. The second transmission gear meshes with the first transmission gear and the third transmission gear. The third transmission gear meshes with the output gear of the second transmission gear, the rack, and the transmission component.

[0018] Furthermore, the end of the transmission component connected to the second charging port locking rod forms a nut with an internal thread, and the nut is fixedly connected to the output gear. The end of the second charging port locking rod connected to the transmission component forms a lead screw that corresponds to the internal thread.

[0019] Furthermore, the first charging port locking rod is retractably mounted on the outer casing via a first connector and a first sealing ring. The first connector is mounted on the AC locking rod opening of the outer casing, and the first sealing ring is mounted on the end of the first charging port locking rod located inside the outer casing, so that the first charging port locking rod and the outer casing form a sealed fit.

[0020] Furthermore, the first charging port locking rod is directly integrally formed with the rack, or the first charging port locking rod is fixed to the rack by any of the following methods: locking, welding, or snap-fitting.

[0021] Furthermore, the second charging port locking rod is retractably mounted on the outer casing via a second connector and a second sealing ring. The second connector is mounted on the DC locking rod opening of the outer casing, and the second sealing ring is mounted on the inner wall of the second connector, so that the second charging port locking rod and the outer casing form a sealed fit.

[0022] Furthermore, the dual-purpose charging gun lock actuator also includes an emergency unlocking mechanism and an emergency unlocking element. The emergency unlocking mechanism is located inside the housing, with one end connected to the rack and the other end protruding outside the housing. The emergency unlocking element is located outside the housing and is connected to the emergency unlocking mechanism extending outside the housing, so that the emergency unlocking element drives the emergency unlocking mechanism to control the rack movement and achieve emergency unlocking.

[0023] Furthermore, the emergency unlocking mechanism includes a rotating rod and a dial fixedly mounted on the rotating rod. The dial has a paddle protruding outward above the rack. The end of the rack opposite to the first charging port locking rod has an upwardly extending lever, and the paddle of the dial is located on the side of the lever closer to the rack. A rotating joint is provided at the top of the rotating rod of the emergency unlocking mechanism. The rotating joint protrudes out of the outer shell and connects to the emergency unlocking element. The emergency unlocking element has an interface corresponding to the rotating joint. The rotating joint is sleeved on the interface. The interface and the rotating joint adopt a non-circular structure for mating. The outer shell and the rotating rod are sealed by a third sealing ring.

[0024] With the above structure, the dual-purpose charging gun lock actuator of this utility model is equipped with a first charging port locking rod and a second charging port locking rod on the outer shell. Through the cooperation of the gear transmission mechanism and the rack, the first charging port locking rod and the second charging port locking rod can be controlled to extend or retract at the same time, thereby realizing the simultaneous locking or unlocking of the AC charging port and the DC charging port, achieving the purpose of dual-purpose locking.

[0025] This invention designs the charging gun lock actuator on the AC charging port to simultaneously lock both the AC and DC charging ports, eliminating the need for an internal lock on the charging gun and saving resource costs. Through the cooperation of a gear transmission mechanism with a rack and pinion and transmission components, the invention converts rotational motion into linear motion in two directions, thereby controlling the extension and retraction of the first and second charging port locking rods to simultaneously lock or unlock both the DC and AC charging ports. Compared to existing technologies, this invention eliminates the need for an internal lock on the charging gun, with the actuator on the AC charging base performing the locking action on both charging ports. This is more economical, and the eliminated locking mechanism allows for a more compact and universal charging gun design, resulting in cost savings, a simplified system structure, and improved charging stability.

[0034] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0035] 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.

[0036] like Figures 1 to 6As shown, this utility model discloses a dual-purpose charging gun lock actuator, which includes a housing 1, a motor 2, a gear transmission mechanism 3, a rack 4, a micro switch 5, a first charging port locking rod 6, a second charging port locking rod 7, a transmission component 8, an emergency unlocking mechanism 9, and an emergency unlocking element 10.

[0037] The outer casing 1 is provided with an AC locking rod opening 11 and a DC locking rod opening 12 for the first charging port locking rod 6 and the second charging port locking rod 7 to extend. The motor 2 is fixedly installed inside the outer casing 1. The output shaft 21 of the motor 2 is fixedly provided with a drive gear 22, which meshes with a gear transmission mechanism 3. The rack 4 is movably installed inside the outer casing 1 and meshes with the gear transmission mechanism 3. A micro switch 5 is installed inside the outer casing 1 to determine the position information of the rack 4. The first charging port locking rod 6 is located at the AC locking rod opening 11 of the outer casing 1, and one end of the first charging port locking rod 6... The second charging port locking rod 7 extends out of the outer shell 1, and the other end is connected to the rack 4. The second charging port locking rod 7 is located at the DC locking rod opening 12 of the outer shell 1. One end of the second charging port locking rod 7 protrudes out of the outer shell 1, and the other end is connected to the transmission component 8. The transmission component 8 meshes with the gear transmission mechanism 3, so that the transmission component 8 drives the second charging port locking rod 7 to extend and retract. One end of the emergency unlocking mechanism 9 is connected to the rack 4, and the other end protrudes out of the outer shell 1 and is fixedly connected to the emergency unlocking element 10, so that the emergency unlocking element 10 drives the emergency unlocking mechanism 9 to control the movement of the rack 4 and realize emergency unlocking.

[0038] The working principle of this utility model's dual-purpose charging gun lock actuator is as follows: Figure 4 As shown, during unlocking, the output shaft 21 of motor 2 and its drive gear 22 rotate clockwise. The drive gear 22 drives the gear transmission mechanism 3 meshing with it. The gear transmission mechanism 3 drives the rack 4 and the first charging port locking rod 6 connected to the rack 4 to move backward to the end opposite to the first charging port locking rod 6, so that the first charging port locking rod 6 retracts, thereby unlocking the DC charging port. At the same time, the gear transmission mechanism 3 drives the transmission component 8 meshing with it to rotate. The transmission component 8 drives the second charging port locking rod 7 to retract, thereby unlocking the DC charging port.

[0039] like Figure 5 As shown, when locked, the output shaft 21 of motor 2 and its drive gear 22 rotate counterclockwise. The drive gear 22 drives the gear transmission mechanism 3 meshing with it to drive. The gear transmission mechanism 3 drives the rack 4 and the first charging port locking rod 6 connected to the rack 4 to move forward to one end of the first charging port locking rod 6, thereby locking the AC charging port. At the same time, the gear transmission mechanism 3 drives the transmission component 8 meshing with it to rotate. The transmission component 8 drives the second charging port locking rod 7 to extend, thereby locking the DC charging port.

[0040] like Figure 6As shown, in an emergency (e.g., when motor 2 cannot work), the emergency unlocking element 10 on the operating housing 1 is activated, which drives the emergency unlocking mechanism 9 to move. The emergency unlocking mechanism 9 drives the rack 4 to move backward, causing the first charging port locking rod 6 and the second charging port locking rod 7 to retract, thereby realizing the emergency unlocking of the AC charging port and the DC charging port.

[0041] This utility model's dual-purpose charging gun lock actuator has a first charging port locking rod 6 and a second charging port locking rod 7 on the outer shell 1. Through the cooperation of the gear transmission mechanism 3 and the rack 4, the first charging port locking rod 6 and the second charging port locking rod 7 can be controlled to extend or retract at the same time, thereby realizing the simultaneous locking or unlocking of the AC charging port and the DC charging port, achieving the purpose of dual-purpose locking.

[0042] In a preferred embodiment of the present invention, the outer shell 1 includes a shell 13 and a cover 14. The AC lock bar port 11 and the DC lock bar port 12 are respectively provided on two adjacent sides of the shell 13. The emergency unlocking element 10 is provided on the cover 14 to facilitate emergency unlocking by the user.

[0043] The gear transmission mechanism 3 can have various structures, and the number of gear sets can be designed according to the specific output force value. For example... Figure 1 As shown, in this embodiment, the gear transmission mechanism 3 includes a first transmission gear 31, a second transmission gear 32, and a third transmission gear 33. The first transmission gear 31, the second transmission gear 32, and the third transmission gear 33 are all double gears with two spur gears. One spur gear of the first transmission gear 31 meshes with the drive gear 22 of the motor 2, and the other spur gear meshes with one spur gear of the second transmission gear 32. The other spur gear of the second transmission gear 32 meshes with one spur gear of the third transmission gear 33. One spur gear of the third transmission gear 33 meshes with the output gear 81 and the second transmission gear 32 provided on the transmission member 8, and the other gear of the third transmission gear 33 meshes with the rack 4.

[0044] The transmission component 8 is connected to the second charging port locking rod 7 by a screw drive. For example... Figure 1 and Figure 2As shown, in this embodiment, the end of the transmission component 8 connected to the second charging port locking rod 7 forms a nut 83 with an internal thread 82. The nut 83 is fixedly connected to the output gear 81. The end of the second charging port locking rod 7 connected to the transmission component 8 forms a lead screw 71 that corresponds to the internal thread 82. When the third transmission gear 33 drives the output gear 81 of the transmission component 8 to rotate, the nut 83 rotates with the output gear 81, and the lead screw 71 on the second charging port locking rod 7 moves back and forth along the internal thread 82, thereby causing the second charging port locking rod 7 to retract inward or extend outward. The gear transmission mechanism 3 can also directly mesh with the output shaft of the motor 2. The output shaft 21 is designed as a structure with a screw. One of the gears of the first transmission gear 31 is a helical gear that meshes with the screw. The screw of the output shaft 21 can drive the helical gear of the first transmission gear 31 to rotate, thereby driving the gear transmission mechanism to run.

[0045] In this embodiment, the first charging port locking rod 6 is retractably mounted on the outer shell 1 via a first connector 61 and a first sealing ring 62. The first connector 61 is mounted on the AC locking rod opening 11 of the outer shell 1, and the first sealing ring 62 is mounted on the end of the first charging port locking rod 6 located inside the outer shell 1, so that the first charging port locking rod 6 and the outer shell 1 form a sealed fit. The first charging port locking rod 6 can be directly integrally formed with the rack 4, or it can be fixed together with the rack 4 by locking, welding, snap-fitting, or other methods.

[0046] The second charging port locking rod 7 is telescopically mounted on the outer shell 1 via the second connector 72 and the second sealing ring 73. The second connector 72 is mounted on the DC locking rod opening 12 of the outer shell 1, and the second sealing ring 73 is mounted on the inner wall of the second connector 72, so that the second charging port locking rod 7 and the outer shell 1 form a sealed fit.

[0047] like Figure 3 As shown, in this embodiment, the emergency unlocking mechanism 9 includes a rotating rod 91 and a dial 92 fixedly mounted on the rotating rod 91. The dial 92 has a paddle 93 protruding above the rack 4. The rack 4 has a lever 41 extending upwards at the end opposite to the first charging port locking rod 6, and the paddle 93 of the dial 92 is located on the side of the lever 41 near the rack 4. Figure 5 and Figure 6As shown, when locking, if the rack 4 moves towards one end of the first charging port locking lever 6 under the drive of the gear transmission mechanism 3, and the lever 41 of the rack 4 abuts against the lever 93, the lever 41 will drive the lever 93 to move forward during the movement of the rack 4. When unlocking, the rack 4 and lever 41 retract, and the lever 93 loses the pushing force of the lever 41 and does not move. When the charging port is locked, the lever 41 moves again to the position abutting against the lever 93. If the actuator malfunctions, causing the motor 2 to fail to run and thus preventing unlocking, the emergency unlocking mechanism 9 can be manually controlled to push the lever 41 backward, thereby driving the rack 4 to retract, which in turn drives the first charging port locking lever 6 and the second charging port locking lever 7 to retract, thus achieving emergency unlocking. Specifically, the top of the rotating rod 91 of the emergency unlocking mechanism 9 is provided with a rotating joint 94. The rotating joint 94 protrudes out of the outer shell 1 and connects to the emergency unlocking element 10. The emergency unlocking element 10 is provided with an interface 101 corresponding to the rotating joint 94. The rotating joint 94 is sleeved on the interface 101. The interface 101 and the rotating joint 94 adopt a non-circular structure to prevent the emergency unlocking element 10 and the rotating rod 91 from rotating freely. The outer shell 1 and the rotating rod 91 are sealed by a third sealing ring 102. The rotation direction can be marked on the outer shell 1 at the position corresponding to the emergency unlocking element 10 for easy user operation.

[0048] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
