Description

Technical Field

[0001] The utility model relates to the technical field of new energy charging seats, and specifically relates to a rotary unlocking mechanism. Background Art

[0002] In the field of new energy vehicles, with the popularization of electric vehicles, charging safety has become an important concern. To ensure the safety and stability during the charging process, new energy vehicle sockets are usually equipped with electronic locking mechanisms to prevent unauthorized plugging and unplugging of the charging gun. However, in some emergency situations, such as vehicle failures or charging system failures, a fast and reliable emergency unlocking mechanism is needed to ensure that the charging gun can be removed in a timely and safe manner.

[0003] Traditional electronic locking mechanisms often rely on electric drive to achieve locking and unlocking functions. However, in the case of power interruption or system failure, this power-dependent unlocking method may not work properly. Therefore, it is particularly important to develop an emergency unlocking mechanism that does not rely on power. Summary of the Utility Model

[0004] In view of the technical problems existing in the prior art, the utility model provides a rotary unlocking mechanism to solve the problem that the electronic lock cannot be unlocked when a failure occurs.

[0005] The technical solution for the utility model to solve the above technical problems is as follows: a rotary unlocking mechanism, based on a first gear in the electronic lock housing for driving the lock rod of the electronic lock, includes a drive shaft for accessing the power source of the electronic lock, and a second gear meshing with the first gear is installed on the drive shaft; an unlocking shaft is also arranged adjacent to the drive shaft in the electronic lock housing; a third gear meshing with the second gear is arranged at one end of the unlocking shaft, and a reset disk is arranged at the other end of the unlocking shaft, and a pull rope is installed on the reset disk;

[0006] When the lock rod of the electronic lock needs emergency unlocking, the pull rope pulls the reset disk to drive the third gear, the second gear and the first gear to rotate in the reverse direction in sequence so that the lock rod of the electronic lock is reset and unlocked.

[0007] Based on the above technical solutions, the utility model can be further improved as follows.

[0008] Further, a pull block is installed at the front end of the pull rope, and a card slot adapted to the pull block is reserved on the reset disk.

[0009] Further, a rope bundling groove is axially formed on the reset disk, and a limiting part is arranged adjacent to the rope bundling groove on the electronic lock housing.

[0010] Further, a guiding cylinder adapted to the pull rope is also arranged on the electronic lock housing.

[0011] Further, a limiting groove is formed in the reset disk along the rotatable direction, and a limiting block adapted to the limiting groove is further installed on the electronic lock housing.

[0012] Further, a handle is installed at the rear end of the pulling rope.

[0013] Moreover, the rotary unlocking mechanism provided by the present utility model has at least the following beneficial effects compared with the prior art:

[0014] 1. The emergency unlocking of the electronic lock rod is realized by operating the pulling rope. Users do not need to rely on electricity or complex operation procedures. They only need to simply pull the pulling rope to complete the unlocking, which greatly improves the operation convenience in case of emergency. The stable connection between the pulling rope and the reset disk (such as the adaptation of the pulling block and the card slot), and the reverse rotation mechanism of the reset disk through gear transmission ensure the reliability of the emergency unlocking. Even in case of power interruption or system failure, users can unlock smoothly.

[0015] 2. The rope-binding groove on the reset disk cooperates with the limiting part on the electronic lock housing to limit the axial movement of the reset disk during rotation, ensuring the stability of the mechanism during operation. At the same time, the guiding cylinder guides and restricts the moving path of the pulling rope, preventing the pulling rope from shifting or winding, and further improving the stability of the mechanism.

[0021] The principles and features of the present utility model are described below with reference to the accompanying drawings. The examples given are only used to explain the present utility model and are not intended to limit the scope of the present utility model.

[0022] It should be noted that, unless otherwise clearly defined and limited, the terms "installation", "connection", and "linkage" in the terminology should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For those of ordinary skill in the art, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0023] As Figure 1 , Figure 2 and Figure 3 shown, the rotary unlocking mechanism of the present utility model is based on a first gear 2 in the electronic lock housing 1 for driving the lock rod of the electronic lock, and includes a drive shaft 3 for accessing the power source of the electronic lock. A second gear 4 meshing with the first gear 2 is installed on the drive shaft 3; an unlocking shaft 5 is also arranged adjacent to the drive shaft 3 in the electronic lock housing 1; one end of the unlocking shaft 5 is provided with a third gear 6 meshing with the second gear 4, and a reset disk 7 is arranged at the other end thereof. A pull rope 8 is installed on the reset disk 7;

[0024] When the lock rod of the electronic lock needs emergency unlocking, the pull rope 8 pulls the reset disk 7 to drive the third gear 6, the second gear 4, and the first gear 2 to rotate in the reverse direction in sequence so as to reset and unlock the lock rod of the electronic lock.

[0025] The emergency unlocking of the lock rod of the electronic lock is realized by operating the pull rope. Under normal circumstances, the power source of the electronic lock drives the second gear 4 to rotate through the drive shaft 3, and then drives the first gear 2 meshing with the second gear 4 to rotate, thereby controlling the locking or unlocking of the lock rod of the electronic lock.

[0026] In the case of emergency unlocking required, such as power interruption or system failure, the user can pull the pull rope 8. The pull rope 8 is connected to the reset disk 7. When the pull rope is pulled, the reset disk 7 rotates accordingly. The rotation of the reset disk 7 is transmitted to the second gear 4 through the third gear 6. Due to the meshing relationship between the gears, the second gear 4 will rotate in the reverse direction. This reverse rotation further drives the first gear 2 to rotate in the reverse direction, finally resetting and unlocking the lock rod of the electronic lock.

[0027] As an implementation manner, a pull block 8.1 is installed at the front end of the pull rope 8, and a card slot 7.1 adapted to the pull block 8.1 is reserved on the reset disk 7.

[0028] In order to operate the pull rope more conveniently and reliably, a pull block 8.1 is installed at the front end of the pull rope 8. The design of this pull block 8.1 enables the user to more easily grasp and pull the pull rope, improving the convenience and efficiency of operation. At the same time, a card slot 7.1 adapted to the pull block 8.1 is reserved on the reset disk 7. When the pull rope is pulled, the pull block 8.1 can accurately be stuck into the card slot 7.1, thereby ensuring the firm connection and synchronous rotation between the pull rope and the reset disk.

[0029] Specifically, a rope bundling groove 7.2 is axially formed in the reset disk 7, and a limiting portion 9 is disposed adjacent to the rope bundling groove 7.2 on the electronic lock housing 1.

[0030] In addition, in order to limit the axial movement of the reset disk during rotation, a rope bundling groove 7.2 is axially formed in the reset disk 7. This rope bundling groove is not only used to accommodate and guide the pulling rope, but also plays a certain limiting role. At the same time, a limiting portion 9 is disposed at a position adjacent to the rope bundling groove 7.2 on the electronic lock housing 1. The limiting portion 9 cooperates with the rope bundling groove 7.2 to jointly limit the axial movement of the reset disk within the electronic lock housing, ensuring the stability and reliability of the reset disk during rotation.

[0031] As an implementation manner, a guiding cylinder 10 adapted to the pulling rope 8 is further provided on the electronic lock housing 1. It guides and restricts the movement path of the pulling rope, preventing the pulling rope from shifting or winding during pulling, and ensuring that the pulling rope can smoothly and stably pull the reset disk 7.

[0032] A limiting groove 7.3 is formed in the reset disk 7 along the rotatable direction, and a limiting block 11 adapted to the limiting groove 7.3 is further installed on the electronic lock housing 1. This design limits the angular range of the reset disk during rotation, preventing it from rotating excessively or undergoing unnecessary displacement.

[0033] In addition, a handle 12 is installed at the rear end of the pulling rope 8. The design of the handle enables the user to more easily grasp and pull the pulling rope. Especially when a large pulling force is required for unlocking, the handle provides a better grip and operating comfort.

[0034] It should be noted that in this article, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, such that a process, method, article or device including a series of elements not only includes those elements but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Unless otherwise expressly stipulated and defined, the terms "install", "connect" and "couple" shall be construed broadly. For example, it may be a fixed connection, a detachable connection or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0035] Although the preferred embodiments of the present utility model have been described, those skilled in the art can make additional changes and modifications once they learn the basic inventive concept. Therefore, the appended claims are intended to be construed to include the preferred embodiments as well as all changes and modifications falling within the scope of the present utility model.

[0036] Obviously, those skilled in the art can make various modifications and variations to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model is also intended to include these modifications and variations.
