Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle technology, specifically to a dual-purpose charging gun lock actuator. 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 dual-purpose charging gun lock actuator that can use one drive device to simultaneously control multiple locking rods to lock and connect 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] This utility model aims to at least partially solve one of the technical problems in the aforementioned technologies. Therefore, one objective of this utility model is to provide a dual-purpose charging gun lock actuator that can simultaneously lock both DC and AC charging ports, offering strong versatility and reducing the number of sub-parts, thus lowering manufacturing costs.

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

[0008] The main moving component is slidably mounted in the housing in the left-right direction, and the main moving component is provided with a rack that meshes with the gear;

[0009] A DC locking rod is movably inserted through the first locking rod hole, and the DC locking rod is connected to the main moving component to slide synchronously with the main moving component;

[0010] The secondary moving part is slidably installed in the housing in the vertical direction. The secondary moving part is slidably connected to the main moving part through a sliding structure so that when the main moving part slides in the left-right direction, it can drive the secondary moving part to slide in the vertical direction.

[0011] An AC locking rod is movably inserted through the second locking rod hole and connected to the secondary moving part so as to slide synchronously with the secondary moving part.

[0012] According to the present invention, a dual-purpose charging gun lock actuator is proposed. The main moving part is driven to slide left and right by a rotating shaft.

This causes the DC locking rod on the main moving part and the AC locking rod on the secondary moving part to move synchronously and extend and retract, thereby realizing synchronous locking between the charging gun and the vehicle body charging socket, reducing the number of sub-parts and reducing manufacturing costs.

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

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.

[0035] 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.

[0036] 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.

[0037] The following is for reference. Figures 1-9 The implementation of the dual-purpose charging gun lock actuator proposed in this embodiment of the present invention will be described in detail.

[0038] The dual-purpose charging gun lock actuator according to an embodiment of the present invention includes:

[0039] Housing 1, housing 1 is provided with a first locking rod hole 11 and a second locking rod hole 12;

[0040] A rotating shaft 2 is rotatably connected to the housing, and a gear 21 is provided at the output end of the rotating shaft 2;

[0041] The main moving part 3 is slidably installed in the housing 1 in the left and right direction. The main moving part 3 is provided with a rack 31 that meshes with the gear 21.

[0042] DC locking rod 4 is movably inserted through the first locking rod hole 11. DC locking rod 4 is connected to the main moving part 3 so as to slide synchronously with the main moving part 3.

[0043] Secondary moving part 5 is slidably installed in the housing 1 in the vertical direction. The secondary moving part 5 is slidably connected to the main moving part 3 through a sliding structure so that when the main moving part 3 slides in the left and right direction, it can drive the secondary moving part 5 to slide in the vertical direction.

[0044] The AC locking rod 6 is movably inserted through the second locking rod hole 12. The AC locking rod 6 is connected to the secondary moving part 5 so as to slide synchronously with the secondary moving part 5.

[0045] In other words, the housing 1 is provided with a first locking rod hole 11 and a second locking rod hole 12 that communicate with the inside and outside of the housing 1. The rotating shaft 2 and the main moving part 3 are connected by gear 21 and rack 31 to convert the rotational motion of the rotating shaft 2 into the linear motion of the main moving part 3, so that the main moving part 3 moves left and right in the housing 1, thereby driving the DC locking rod 4 to move and extend in the first locking rod hole 11. The main moving part 3 and the secondary moving part 5 are slidably connected by a sliding structure, so that the main moving part 3 and the secondary moving part 5 can slide relative to each other. Since the main moving part 3 and the secondary moving part 5 are both restricted to a single sliding direction by the housing 1, when the main moving part 3 slides left and right, it can drive the secondary moving part 5 to slide up and down through the sliding structure, thereby synchronously driving the AC locking rod 6 to move and extend in the second locking rod hole 12. In this way, the synchronous extension and retraction of the DC locking rod 4 and the AC locking rod 6 can lock or unlock the charging gun and the vehicle body charging socket 8 synchronously, improve versatility, reduce the number of sub-parts, and reduce manufacturing costs.

[0046] The rotating shaft 2 can be driven by a motor in conjunction with a gear set. The rotating shaft 2 is provided with teeth that mesh with the gear set. The first locking rod hole 11 and the second locking rod hole 12 can be set according to the locking hole position of the vehicle charging base 8, or they can be aligned with the locking hole position of the vehicle charging base 8 by the bending of the DC locking rod 4 and the AC locking rod 6. The sliding structure can be a sliding groove and a slider between the main moving part 3 and the secondary moving part 5. The sliding groove can be a straight sliding groove with an inclination, or it can be an arc groove. Of course, a standard guide rail can also be used. The sliding function of the main moving part 3 and the secondary moving part 5 can be realized by a linear guide rail, or it can be realized by direct sliding contact between the main moving part 3 and the secondary moving part 5 and the concave and convex parts of the housing 1. The first locking rod hole 11 and the second locking rod hole 12 can extend outward from the housing 1 to improve the restriction of the DC locking rod 4 and the AC locking rod 6 in the circumferential direction and prevent the DC locking rod 4 and the AC locking rod 6 from swaying. The housing 1 can be composed of two detachable parts. The lock actuator can be set on the vehicle charging base 8.

[0047] Therefore, the main moving part 3 is driven to slide left and right by the rotating shaft 2. When the main moving part 3 slides, the sliding structure between the main moving part 3 and the secondary moving part 5 drives the secondary moving part 5 to slide up and down, thereby driving the DC locking rod 4 on the main moving part 3 and the AC locking rod 6 on the secondary moving part 5 to move synchronously, realizing synchronous locking between the charging gun and the vehicle body charging base 8, reducing the number of sub-parts and reducing manufacturing costs.

[0048] Optionally, the housing 1 is provided with a first sliding groove 13 arranged in the left-right direction, and the main moving member 3 is provided with a first protrusion 32 adapted to the first sliding groove 13. Understandably, through the sliding engagement of the first sliding groove 13 and the first protrusion 32, the main moving member 3 can slide in the left-right direction within the housing 1, thereby facilitating the main moving member 3 to drive the DC locking rod 4 to extend and retract, thus locking the charging gun of the DC charging port and the vehicle body charging base 8. The first sliding groove 13 can be formed by two protruding edges spaced apart on the housing 1, and the first protrusion 32 can be cylindrical and located on one side of the rack 31.

[0049] Optionally, the housing 1 is provided with a second sliding groove 14 arranged in the vertical direction, and the secondary moving member 5 is provided with a second protrusion 51 adapted to the second sliding groove 14. Understandably, through the sliding engagement of the second sliding groove 14 and the second protrusion 51, the secondary moving member 5 can slide vertically within the housing 1, thereby facilitating the main moving member 3 to drive the AC locking lever 6 to extend and retract, thus locking the charging gun of the AC charging port and the vehicle body charging socket 8. The second sliding groove 14 can be formed by a recess in the housing 1, and the first protrusion 32 can be cylindrical.

[0050] Optionally, the sliding structure includes a third slide groove 52 and a third protrusion 33 adapted to the third slide groove 52. The third slide groove 52 is inclined towards the DC locking rod 4 from bottom to top. Understandably, through the sliding engagement of the third slide groove 52 and the third protrusion 33, and with the third slide groove 52 inclined towards the DC locking rod 4 from bottom to top, the sliding engagement of the third slide groove 52 and the third protrusion 33 in the inclined direction facilitates the gradual sliding of the secondary moving part 5 up and down when the main moving part 3 slides left and right, thereby achieving synchronous locking or unlocking of the DC locking rod 4 and the AC locking rod 6. The third slide groove 52 can be disposed on the secondary moving part 5 or the main moving part 3, and the third protrusion 33 can be correspondingly disposed on the main moving part 3 or the secondary moving part 5. Preferably, the third slide groove 52 is disposed on the secondary moving part 5, and the third protrusion 33 is disposed on the main moving part 3 and located on one side of the rack 31.

[0051] Optionally, the main moving component 3 is provided with a first connecting hole 34, and the DC locking rod 4 is connected to the first connecting hole 34. Understandably, the first connecting hole 34 facilitates the installation and connection of the DC locking rod 4, thereby enabling the main moving component 3 to synchronously slide and extend / retract the DC locking rod 4 when it slides. The DC locking rod 4 and the first connecting hole 34 can be threaded together.

[0052] Furthermore, the main moving component 3 is provided with a second connecting hole 35 that radially communicates with the first connecting hole 34, and the DC locking rod 4 is provided with a third connecting hole 41 that communicates with the second connecting hole 35. The second connecting hole 35 and the third connecting hole 41 are connected by a fixing pin 7. Understandably, by passing the fixing pin 7 through the second connecting hole 35 and the third connecting hole 41, the axial direction of the DC locking rod 4 can be fixed. Combined with the circumferential restriction of the first connecting hole 34 and the first locking rod hole 11, the reliability of the connection of the DC locking rod 4 is ensured.

[0053] Optionally, the secondary moving part 5 is provided with a bayonet 53, and the AC locking rod 6 is provided with a slot 61, which engages with the bayonet 53. Understandably, by engaging the bayonet 53 with the slot 61, the axial direction of the DC locking rod 4 can be restricted. Combined with the circumferential restriction of the second locking rod hole 12, the reliability of the DC locking rod 4 connection is ensured, while facilitating the quick installation of the DC locking rod 4 and improving installation efficiency.

[0054] Optionally, the locking end of the DC locking lever 4 and the locking end of the AC locking lever 6 are arranged at a spatial angle. Understandably, existing DC and AC charging ports are arranged side-by-side. The AC locking lever 6 of the AC charging port extends into the AC charging port from the side to achieve the locking function, while the DC locking lever 4 of the DC charging port extends from above the DC charging port along the insertion direction of the charging gun to achieve the locking function. The spatial angle between the locking ends of the DC locking lever 4 and the AC locking lever 6 facilitates compatibility with existing locking methods of DC and AC charging ports. The portions of the DC locking lever 4 and AC locking lever 6 exposed in the housing 1 can be bent to form a spatial angle, while the portions inside the housing 1 can be straight segments, and the spatial angle between them can be 90°.

[0055] Optionally, the AC locking lever 6 is in a straight line and the DC locking lever 4 is in a Z-shape. Understandably, by setting the AC locking lever 6 to be in a straight line and the DC locking lever 4 to be in a Z-shape, it is easier for the AC locking lever 6 and the DC locking lever 4 to match the existing locking positions. The AC locking lever 6 does not need to be bent, and the DC locking lever 4 is bent outside the housing 1, which can reduce the space occupied by the actuator body.

[0056] Optionally, the rotating shaft 2 also includes an emergency drive end, which is located outside the housing 1. Understandably, in the event of a failure of the drive source, the AC locking lever 6, or the DC locking lever 4, manually rotating the emergency drive end of the rotating shaft 2 can drive the gear 21 on the rotating shaft 2 to rotate, thereby allowing manual extension or retraction of the AC locking lever 6 or the DC locking lever 4 for locking or unlocking in an emergency. The cross-section of the emergency drive end can be rectangular to facilitate the use of a matching tool to rotate the rotating shaft 2.
