Description

Technical Field

[0001] The utility model relates to the technical field of charging sockets, and particularly to an electronic lock unlocking mechanism that can be unlocked from the front end. Background Art

[0002] In the field of new energy electric vehicles, the safety and reliability of the charging connection device are one of the key factors to ensure the smooth progress of the charging process. As a key component connecting the electric vehicle and the charging pile, the design of the locking mechanism of the charging gun is particularly important. Traditionally, after the charging gun is inserted into the charging interface of the electric vehicle, it will be fixed by the locking mechanism to prevent the charging gun from accidentally falling off during the charging process, thereby ensuring the safety and stability of the charging process.

[0003] However, in the actual use process, the locking mechanism of the charging gun may encounter various abnormal situations, such as damage to the charging gun, electrical circuit failure in the vehicle, etc. These situations may cause the locking mechanism to fail to unlock normally, thereby affecting the removal of the charging gun. At this time, if there is no effective emergency unlocking mechanism, it will bring great inconvenience to users and may even cause potential safety hazards. Summary of the Utility Model

[0004] In view of the technical problems existing in the prior art, the utility model provides an electronic lock unlocking mechanism that can be unlocked from the front end to solve the problem that the locking mechanism cannot be unlocked normally.

[0005] The technical solution of the utility model to solve the above technical problems is as follows: An electronic lock unlocking mechanism that can be unlocked from the front end, including a main housing, a locking metal rod is arranged in the main housing along the gun insertion direction of the charging gun; a push rod connected to the locking metal rod and a locking mechanism connected to the push rod are also arranged in the main housing; the locking mechanism can drive the push rod to reciprocate to make the locking metal rod expand and contract; a reset unlocking mechanism connected to the push rod is also arranged in the main housing, and the reset unlocking mechanism can drive the push rod to reset to unlock the locking metal rod.

[0006] On the basis of the above technical solution, the utility model can be further improved as follows.

[0007] Further, the locking mechanism includes:

[0008] A driving cylinder sleeved outside the push rod and slidably matched with the push rod;

[0009] A guiding part arranged in the main housing, and a spiral groove cooperating with the guiding part is formed on the outside of the push rod;

[0010] A driving gear arranged outside the driving cylinder;

[0011] An electric motor driving part connected to the driving gear.

[0012] Further, the reset unlocking mechanism comprises:

[0013] A reset rod is coaxially arranged with the push rod and the drive cylinder;

[0014] A limiting member is sleeved outside the reset rod and extends along the push rod, and the push rod is provided with a travel groove along the length direction for slidingly cooperating with the limiting member;

[0015] A spring is sleeved outside the reset rod and elastically supports the limiting member.

[0016] Further, the reset unlocking mechanism also includes:

[0017] A transmission arm slidably arranged outside the main housing;

[0018] A lever extends along the transmission arm toward the reset rod and is connected to the reset rod.

[0019] Furthermore, the shifting rod is slidably matched with the reset rod, and the reset rod is also provided with a shifting part adapted to the shifting rod.

[0020] Furthermore, a front unlocking lever is provided on the outer edge of the transmission arm in the extension and retraction direction of the gun locking metal rod.

[0021] Furthermore, a sealing ring is also arranged on the reset rod.

[0022] Moreover, the front-end unlocking electronic lock unlocking mechanism provided by the present invention has at least the following beneficial effects compared with the prior art:

[0023] 1. The precise design of the locking mechanism enables efficient locking of the charging gun. The motor drive provides power to drive the gear to rotate, which in turn causes the push rod to move back and forth through the spiral transmission mechanism, driving the metal rod of the lock gun to extend and retract, thus achieving stable locking of the charging gun.

[0024] 2. Provide emergency unlocking function when the locking mechanism cannot be unlocked normally. The reset unlocking mechanism can respond quickly, overcome the elastic force of the spring through external operation, reset the push rod, and drive the metal rod of the lock gun to contract and achieve quick unlocking.

[0025] 3. By designing an unlocking mechanism that can be directly operated at the front end, users can unlock the device without entering the device or performing complex operations, which greatly simplifies the operation process and improves the efficiency of use. This is especially important for rapid response in emergency situations, such as quickly unlocking the charging gun in an electric vehicle charging station to reduce user waiting time.

Specific embodiments

[0031] The principles and features of the present utility model will be described below with reference to the accompanying drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.

[0032] It should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" in the terms 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.

[0033] As Figure 1 、 Figure 2 and Figure 3 shown, the unlock mechanism of the electronically lockable front-end unlockable design of the present utility model includes a main housing 1. The main housing 1 is provided with a locking metal rod 2 for the charging gun along the insertion direction of the charging gun; a push rod 3 connected to the locking metal rod 2 and a locking mechanism 4 connected to the push rod 3 are further provided inside the main housing 1; the locking mechanism 4 can drive the push rod 3 to reciprocate to make the locking metal rod 2 expand and contract; a reset unlocking mechanism 5 connected to the push rod 3 is further provided inside the main housing 1, and the reset unlocking mechanism 5 can drive the push rod 3 to reset to unlock the locking metal rod 2.

[0034] The main housing 1 serves as the support structure of the entire mechanism and is provided with a locking metal rod 2 for the charging gun along the insertion direction of the charging gun to lock the charging gun when the charging gun is inserted.

[0035] When the charging gun is inserted in place, the locking mechanism 4 starts to work. The locking mechanism 4 drives the component connected to the push rod 3 to make the push rod 3 reciprocate inside the main housing 1. The movement of the push rod 3 further drives the locking metal rod 2 to expand and contract to achieve the locking of the charging gun.

[0036] When normal unlocking fails, the unlocking mechanism 5 can be reset to drive the push rod 3 to reset for unlocking.

[0037] As an implementation, the locking mechanism 4 includes:

[0038] A driving cylinder 4.1 sleeved outside the push rod 3 and slidably matched with the push rod 3;

[0039] A guiding part 4.2 arranged inside the main housing 1, and a spiral groove 3.1 cooperating with the guiding part 4.2 is formed outside the push rod 3;

[0040] A driving gear 4.3 arranged outside the driving cylinder 4.1;

[0041] An electric motor driving part 4.4 connected to the driving gear 4.3.

[0042] The locking mechanism 4 is powered by the electric motor driving part 4.4 to drive the driving gear 4.3 connected to the driving cylinder 4.1 to rotate. The driving cylinder 4.1 is sleeved outside the push rod 3 and is slidably matched with the push rod 3. The spiral groove 3.1 formed outside the push rod 3 cooperates with the guiding part 4.2 arranged inside the main housing 1 to form a spiral transmission mechanism. When the driving gear 4.3 rotates, the rotational motion is converted into a linear reciprocating motion of the push rod 3 through the driving cylinder 4.1. This linear motion further drives the charging gun metal rod 2 to expand and contract, realizing the locking or unlocking of the charging gun.

[0043] As an implementation, the reset unlocking mechanism 5 includes:

[0044] A reset rod 5.1 coaxially arranged with the push rod 3 and the driving cylinder 4.1;

[0045] A limiting part 5.2 sleeved outside the reset rod 5.1 and extending along the push rod 3, and a travel groove 5.3 slidably matched with the limiting part 5.2 is formed in the push rod 3 along the length direction;

[0046] A spring 5.4 sleeved outside the reset rod 5.1 and elastically supporting the limiting part 5.2.

[0047] The reset unlocking mechanism 5 is designed to reset the push rod 3 when needed to unlock the charging gun. It mainly includes a reset rod 5.1, a limiting part 5.2 and a spring 5.4. The reset rod 5.1 is coaxially arranged with the push rod 3 and the driving cylinder 4.1, providing a stable axis for the reset process. The limiting part 5.2 is sleeved outside the reset rod 5.1 and extends along the length direction of the push rod 3. The travel groove 5.3 formed in the push rod 3 is slidably matched with the limiting part 5.2, allowing the limiting part 5.2 to move on the push rod 3. The spring 5.4 is sleeved outside the reset rod 5.1 and elastically supports the limiting part 5.2 to keep a certain pre-tightening force.

[0048] During the unlocking process, the elastic force of the spring 5.4 is overcome by external operation (such as manual pressing or mechanical triggering), so that the limiter 5.2 slides in the travel groove 5.3, thereby driving the push rod 3 to reset. The reset of the push rod 3 causes the lock gun metal rod 2 to contract, and finally the charging gun is unlocked.

[0049] In addition, the reset unlocking mechanism 5 also includes:

[0050] A transmission arm 5.5 slidably arranged outside the main housing 1;

[0051] A lever 5.6 extends along the transmission arm 5.5 toward the reset rod 5.1 and is connected to the reset rod 5.1.

[0052] The lever 5.6 extends along the transmission arm 5.5 toward the reset lever 5.1 and is connected to the reset lever 5.1. This connection allows the user to indirectly control the lever 5.6 by operating the transmission arm 5.5, thereby affecting the position of the reset lever 5.1.

[0053] As an implementation mode, the lever 5.6 is slidably matched with the reset lever 5.1, and the reset lever 5.1 is also provided with a toggle portion 5.7 adapted to the lever 5.6. The reset lever 5.1 is provided with a toggle portion 5.7 adapted to the lever 5.6, ensuring that the lever 5.6 can accurately and reliably act on the reset lever 5.1 to achieve the expected unlocking action.

[0054] The transmission arm 5.5 is also provided with a front unlocking lever 5.8 along the extension direction of the locking gun metal rod 2. The design of the front unlocking lever 5.8 allows the user to directly operate the charging gun from the outside so as to quickly unlock the charging gun when needed. This design improves the convenience of operation and user experience.

[0055] The reset rod 5.1 is also provided with a sealing ring 5.9, the main function of which is to prevent dust, moisture and other impurities from entering the main housing 1, thereby protecting the reset unlocking mechanism 5 and other internal components from contamination and damage.

[0056] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. Unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the utility model can be understood according to the specific circumstances.
