Description

Technical Field

[0001] This utility model relates to the field of new energy vehicles, specifically to a linkage electronic lock in charging products. Background Technology

[0002] With the rapid development of new energy vehicles, the industry has gained a deeper understanding of related products and has placed higher demands on product quality and user experience. To ensure the safety and reliability of the charging process for new energy vehicles and prevent situations such as live plugging and unplugging (which may cause arcing of the charging plug and socket, leading to contact erosion), the national standard GB_T 20234.1-2023 Electric Vehicle Conductive Charging Connection Device Part 1: General Requirements clearly stipulates that AC charging sockets with an A rating of 16A or higher should be equipped with electronic lock devices, making electronic locks an important component of vehicle charging sockets. However, due to the limited understanding of new energy vehicle charging scenarios in the early stages, most electronic locks on the market currently suffer from poor reliability and poor user experience, which are becoming increasingly prominent pain points.

[0003] Most charging sockets come with both DC and AC charging sockets, but currently most on the market only have electronic locks designed for AC charging sockets to prevent the charging gun from being pulled out during charging. This results in limited charging options for new energy vehicles, and also lower safety when using DC charging guns.

[0004] Furthermore, because the existing electronic locks use a traditional linkage mechanism for driving, the transmission efficiency is low and the structure is complex. The assembly process with the socket is very cumbersome, which is not conducive to the installation process and subsequent maintenance. Utility Model Content

[0005] The purpose of this invention is to improve the structure of existing electronic locks so that they can simultaneously lock both DC and AC charging guns, and to improve the overall ease of installation through structural improvements.

[0006] To achieve the above objectives, the present invention provides the following solution:

[0007] An electronic lock includes a housing and a driver, a first gear connected to the driver's output shaft, a second gear assembly and a third gear assembly meshing with the first gear in two different directions.

[0008] The second gear assembly and the third gear assembly are respectively provided with locking rods extending in different directions.

[0009] In the above technical solution, the second gear assembly is provided with a first locking rod, and the direction in which the first gear meshes with the second gear assembly is consistent with the direction in which the first locking rod extends.

[0010] The third gear assembly is provided with a second locking rod, and the direction in which the first gear meshes with the second gear assembly is consistent with the direction in which the second locking rod extends.

[0011] In the above technical solution, the first locking rod extends vertically, and the second locking rod extends horizontally.

[0012] In the above technical solution, the locking rod on the second gear assembly and the locking rod on the third gear assembly do not interfere with each other in space.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] This application adopts an innovative gear and rack design, with the same gear driving different racks to ensure locking and unlocking in different directions, thus ensuring the safety of DC and AC sockets.

[0015] The design of this application, in which the same gear drives the double racks to move in different directions, can ensure that the AC socket and DC socket can be locked and unlocked at the same time, and can also increase the holding force of the locking rod. The reason for the increased holding force of the locking rod is the rack transmission in different directions. The thrust in one direction cannot dissipate the force in the vertical direction, ensuring that the locking rod will not retract due to misoperation during the charging process, thus preventing the gun from being pulled out.

[0016] The actuator of this application uses a direct-drive gear mechanism, which provides greater driving force and better ice-breaking performance in low-temperature environments.

[0017] The overall design of this application is simple, with fewer parts required for assembly and fitting, resulting in high production efficiency, lower ppm, and a lighter product. Attached Figure Description

Detailed Implementation

[0023] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0024] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0025] like Figure 1 As shown, this embodiment includes a driver 1, a gearbox cover 3, a gearbox housing 6, and a gear assembly disposed therein. The gear assembly includes a drive gear 2 (first gear), a DC socket rack assembly 4 (second gear assembly), and an AC socket rack assembly 5 (third gear assembly). The gearbox housing 6 and the driver 1 are interlocked by a double-sided three-clamp structure to ensure that the gearbox assembly does not fall off during operation.

[0026] like Figure 2 and Figure 3 As shown, the DC socket rack assembly 4 in this embodiment is manufactured using a one-piece injection molding process, forming a bridge-like structure with its two ends parallel to each other. One end is a gear 4.2 for meshing with the drive gear 2, and the other end is a DC socket rack assembly locking rod 4.1 (first locking rod) for locking the DC charging plug. The DC socket rack assembly 4 meshes with the drive gear 2 in a vertical direction, allowing it to move up and down in the vertical direction while the drive gear 2 rotates.

[0027] In this embodiment, the AC socket rack assembly 5 is a rectangular rack structure. A locking rod 5.1 (second locking rod) is provided at one end along the direction of the rack. A gear 5.2, which meshes with the drive gear 2, is provided on the surface of the rack. The drive gear 2 meshes with the AC socket rack assembly 5 in the horizontal direction, driving the AC socket rack assembly 5 to lock the AC charging plug in the horizontal direction.

[0028] like Figure 3 As shown, the DC socket rack assembly locking rod 4.1 (first locking rod) and the AC socket rack assembly locking rod 5.1 (second locking rod) do not interfere with each other in space. Driven by the drive gear 2, they are synchronously transmitted, one moving up and down along the drive gear 2 and the other moving horizontally along the drive gear 2.

[0029] In this embodiment, the DC socket rack assembly locking rod 4.1 (first locking rod) and the DC socket rack assembly 4, the AC socket rack assembly locking rod 5.1 (second locking rod) and the AC socket rack assembly 5 are all made using an integral injection molding process to ensure that there is no relative displacement between them during transmission, thus ensuring the locking accuracy of the DC socket or the AC socket.

[0030] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
