Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle technology, specifically to a charging gun lock actuator and a charging gun. Background Technology

[0002] In existing charging technologies, when a charging dock has multiple charging ports, such as both DC and AC charging ports, different charging guns can be used for charging. Current solutions all use multiple drive devices to control the locking connection between the multiple charging ports and the charging guns. Each drive device drives a corresponding locking lever to lock the charging gun onto the corresponding charging dock for charging. This approach suffers from problems such as a large number of drive device parts and high manufacturing costs.

[0003] Therefore, there is an urgent need in the field of new energy vehicle technology for a charging gun lock actuator that can use a single drive device to simultaneously control multiple locking rods to lock the charging gun, overcoming the shortcomings of existing technologies and solving problems such as the large number of drive device parts and high manufacturing costs. Utility Model Content

[0004] The present invention aims to at least partially solve one of the technical problems in the aforementioned technologies. Therefore, one objective of the present invention is to provide a charging gun lock actuator that has a stable locking function, reduces the number of sub-parts, and effectively lowers manufacturing costs.

[0005] To achieve the above objectives, this utility model proposes a charging gun lock actuator, comprising:

[0006] case;

[0007] A drive motor installed inside the housing, wherein the output end of the drive motor is provided with a first gear;

[0008] A variable speed gear set installed inside the housing, wherein the input end of the variable speed gear set meshes with the first gear;

[0009] A first locking rod is movably inserted through the housing. The first locking rod is provided with a first rack and a second rack. The first rack meshes with the output end of the transmission gear set so that the second rack can move synchronously with the first locking rod.

[0010] A second gear is installed inside the housing, and the second gear meshes with the second rack.

[0011] A second locking rod is movably inserted through the housing. The second locking rod is provided with a third rack, which meshes with the second gear to enable the second locking rod to extend and retract.

[0012] According to this utility model, a charging gun lock actuator can improve the extension and retraction force of the first locking rod through the cooperation of a drive motor and a transmission gear set. The extension and retraction of the first locking rod can drive the second locking rod to extend and retract synchronously, thereby achieving synchronous locking of the AC charging station and the DC charging station by a single drive motor driving the first and second locking rods. This not only improves the stability of the locking function of the charging gun lock actuator but also reduces the number of sub-parts, effectively lowering manufacturing costs.

[0013] In addition, the charging gun lock actuator proposed in the above embodiments of this utility model may also have the following additional technical features:

[0014] Optionally, it also includes an emergency unlocking component, which includes a pivot and a lever mounted on the pivot. When the pivot rotates, it can drive the lever to swing, so that the lever can drive the first locking rod to extend and retract.

[0015] Optionally, it also includes a seal for sealing between the first locking rod and the housing, and between the second locking rod and the housing.

[0016] Optionally, the first locking rod and the second locking rod are arranged at an angle.

[0017] Optionally, the first rack is horizontally arranged and located below the gear set, and the second rack is vertically arranged and located on one side of the first rack.

[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0029] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0030] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0031] The following is for reference. Figures 1-3 The implementation of the charging gun lock actuator proposed in the embodiments of this utility model will be described in detail.

[0032] The charging gun lock actuator according to an embodiment of the present utility model includes:

[0033] Casing 1;

[0034] A drive motor 2 is installed inside the housing 1, and the output end of the drive motor 2 is provided with a first gear 21;

[0035] The gear set 3 is installed inside the housing 1, and the input end of the gear set 3 meshes with the first gear 21;

[0036] A first locking rod 4 is movably inserted through the housing 1. The first locking rod 4 is provided with a first rack 411 and a second rack 412. The first rack 411 meshes with the output end of the transmission gear set 3 so that the second rack 412 can move synchronously with the first locking rod 4.

[0037] The second gear 5 is installed inside the housing 1, and the second gear 5 meshes with the second rack 412;

[0038] The second locking rod 6 is movably installed in the housing 1. The second locking rod 6 is provided with a third rack 611, which meshes with the second gear 5 so that the second locking rod 6 can extend and retract.

[0039] In other words, the first gear 21 on the output end of the drive motor 2 meshes with the input end of the gear set 3, enabling the drive motor 2 to drive the gear set 3 to rotate when it is working. This changes the original speed of the drive motor 2, thereby increasing the torque and providing a greater output driving force to the output end of the gear set 3. The output end of the gear set 3 meshes with the first rack 411 of the first locking rod 4, enabling the gear set 3 to drive the first locking rod 4 to perform linear extension and retraction. When the first locking rod 4 extends and retracts, it drives the second rack 412 to extend and retract synchronously, causing the second gear 5 meshing with the second rack 412 to rotate and drive the third rack 611 meshing with the second gear 5 to perform linear extension and retraction. This allows the second locking rod 6 to synchronously follow the extension and retraction of the first locking rod 4. That is, one drive motor 2 drives two locking rods to lock synchronously after the gear set 3 changes speed, improving the stability of the extension and retraction of the two locking rods and reducing the number of sub-parts, effectively reducing manufacturing costs. The charging gun lock actuator can be installed on the charging gun of the charging pile or on the charging dock of the car. The first locking rod 4 and the second locking rod 6 can be locked and unlocked through telescopic in-and-out holes or slots. The telescopic direction of the first locking rod 4 and the second locking rod 6 can be set according to the distribution of AC charging station and DC charging station. They can be set on the same horizontal plane or on different horizontal planes. The housing 1 can be provided with a sliding groove for the first locking rod 4 and the second locking rod 6 to slide in a specified direction, while maintaining the meshing degree between the first rack 411 and the gear set 3, and between the second rack 412 and the second gear 5. The first rack 411 and the second rack 412 are located in the housing 1, and the locking part of the first locking rod 4 and the second locking rod 6 is movably inserted through the through hole on the housing 1. The housing 1 includes a base 11 and a cover plate 12. The base 11 and the cover plate 12 together form a receiving space. The base 11 and the cover plate 12 can be connected by screws, fastening, or a combination of sliding groove and fastening.

[0040] Therefore, by cooperating with the drive motor 2 and the transmission gear set 3, the extension and retraction force of the first locking rod 4 can be increased. When the first locking rod 4 extends and retracts, it can drive the second locking rod 6 to extend and retract synchronously, thereby realizing the synchronous locking of the AC charging station and the DC charging station by one drive motor 2 driving the first locking rod 4 and the second locking rod 6. This not only improves the stability of the locking function of the charging gun lock actuator, but also reduces the number of sub-parts and effectively reduces manufacturing costs.

[0041] Optionally, an emergency unlocking component 7 is also included. The emergency unlocking component 7 includes a rotating shaft 71 and a toggle element 72 mounted on the rotating shaft 71. When the rotating shaft 71 rotates, it can cause the toggle element 72 to swing, thereby causing the toggle element 72 to extend and retract the first locking rod 4. Understandably, when the external power supply to the drive motor 2 is unavailable or the drive motor 2 malfunctions, the emergency unlocking component 7 can be manually rotated to lock or unlock. When the emergency unlocking component 7 is rotated, the rotating shaft 71 can cause the toggle element 72 to swing synchronously, and the toggle element 72 then causes the first locking rod 4 to extend and retract, thus achieving locking or unlocking in emergency situations. The rotating shaft 71 passes through the housing 1, and the operating end of the rotating shaft 71 is located outside the housing 1. A toggle switch 73 can be provided at the operating end of the rotating shaft 71. The toggle switch 73 and the rotating shaft 71 can be detachably connected, similar to the connection structure of a lockable faucet. A sealing element 8 can also be provided between the rotating shaft 71 and the housing 1.

[0042] Optionally, a seal 8 is also included, which is used for sealing between the first locking rod 4 and the housing 1, and between the second locking rod 6 and the housing 1. Understandably, by providing the seal 8, the sealing performance inside and outside the housing 1 can be improved, thereby enhancing the waterproof and dustproof performance of the charging gun lock actuator. The housing 1 has a mounting groove 13 with a through hole at the bottom. The seal 8 is fitted onto the first locking rod 4 and the second locking rod 6 and installed within the mounting groove 13, allowing the seal 8 to tightly wrap around the outer circumferential surfaces of the first locking rod 4 and the second locking rod 6. A sealing cap 9 can also be provided to cooperate with the outer circumferential wall of the mounting groove 13, so that the seal 8 can be confined within the mounting groove 13, preventing axial displacement of the seal 8 during the extension and retraction of the first locking rod 4 and the second locking rod 6. The mounting groove 13 and the through hole can be integrally formed on the housing 1, and the sealing cap 9 can be threadedly connected to the outer wall of the mounting groove 13. The seal 8 can be a sealing ring made of rubber or silicone.

[0043] Optionally, the first locking lever 4 and the second locking lever 6 are arranged at an angle. Understandably, by arranging the first locking lever 4 and the second locking lever 6 at an angle, it is possible to better match the distribution of existing AC charging stations and DC charging stations on the market, thereby locking the charging station and the charging gun. Specifically, the first locking lever 4 and the second locking lever 6 can be at the same horizontal level, and the angle between them can be 90°. The first locking lever 4 can be used to lock the AC charging station, and the second locking lever 6 can be used to lock the DC charging station.

[0044] Optionally, the first rack 411 is horizontally positioned below the gear set 3, and the second rack 412 is vertically positioned to one side of the first rack 411. Understandably, by having the first rack 411 horizontally positioned below the gear set 3 and the second rack 412 vertically positioned to one side of the first rack 411, the layout becomes more rational, the overall structure more compact, and the space occupied by the charging gun lock actuator is significantly reduced.

[0045] Furthermore, the first locking lever 4 includes a first connecting member 41, and a first rack 411 and a second rack 412 are disposed on two adjacent surfaces of the first connection. Understandably, by using the first connecting member 41, the first locking lever 4 and the first rack 411 and second rack 412 are prevented from being integrally formed, thereby reducing manufacturing difficulty and cost. By disposing the first rack 411 and second rack 412 on two adjacent surfaces of the first connection, it is easier for the transmission gear set 3 and the second gear 5 to be staggered, avoiding mutual interference. The first locking lever 4 and the first connecting member 41 can be detachably connected via a U-shaped groove on the lever body and the first connecting member 41, facilitating installation and replacement. When the actuating member 72 swings, it can contact the first connecting member 41 and drive the first connecting member 41 to move, thereby driving the first locking lever 4 to extend and retract.

[0046] Optionally, the second locking rod 6 includes a second connecting member 61, and a third rack 611 is disposed on the second connecting member 61. Understandably, by using the second connecting member 61, the second locking rod 6 and the third rack 611 are avoided from being integrally formed, thereby reducing manufacturing difficulty and cost. The second locking rod 6 and the second connecting member 61 can be detachably connected via a rod body and a U-shaped groove on the first connecting member 41, facilitating installation and replacement.

[0047] Optionally, a detection switch 10 is also included. The detection switch 10 is disposed on one side of the first locking rod 4 to detect the extension and retraction state of the first locking rod 4. Understandably, by setting the detection switch 10, the extension and retraction state of the first locking rod 4 can be accurately monitored, thereby facilitating the monitoring of the extension and retraction states of the first locking rod 4 and the second locking rod 6. The detection switch 10 can be a microswitch, installed inside the housing 1, and can be triggered by engaging with the inclined surface of the first connecting member 41.

[0048] Optionally, the transmission gear set 3 includes a first double gear 31, a second double gear 32, and a third double gear 33. The first double gear 31 meshes with the first gear 21, the second double gear 32 meshes with the first double gear 31, and the third double gear 33 meshes with the second double gear 32 and the first rack 411. Understandably, each of the first double gear 31, the second double gear 32, and the third double gear 33 includes a large gear and a small gear. The first gear 21 meshes with the large gear of the first double gear 31, the large gear of the second double gear 32 meshes with the small gear of the first double gear 31, the large gear of the third double gear 33 meshes with the small gear of the second double gear 32, and the first rack 411 meshes with the small gear of the third double gear 33. This creates variations in the speed and torque of the drive motor 2, improving the reliability of the extension and retraction of the first locking lever 4 and the second locking lever 6. Among them, the first double gear 31, the second double gear 32 and the third double gear 33 can be rotatably connected by a support member integrally formed in the housing 1, and the second gear 5 can adopt a structure of two semi-circular gears facing different directions, which is convenient for saving materials.

[0049] Furthermore, this utility model also proposes a charging gun, wherein the charging gun includes the aforementioned charging gun lock actuator. It is understood that by setting the charging gun lock actuator on this charging gun, the charging gun and the car's charging dock can be stably locked and unlocked simultaneously for both DC and AC charging positions. This also reduces the number of sub-parts, saves costs, and makes the overall charging gun structure more compact and space-saving. The charging gun lock actuator can be installed inside the charging gun, with only the first locking rod 4 and the second locking rod 5 extending and retracting inside and outside the charging gun, or it can be installed outside the charging gun.
