Description

Technical Field

[0001] This utility model relates to the field of new energy electric vehicles, and in particular to a charging gun locking structure. Background Technology

[0002] With the rapid development of electric vehicles, vehicle charging technology has become an important research direction. Charging a vehicle relies on the cooperation of a charging gun and a charging port. According to industry standards, a locking device is required between the charging gun and the charging port to prevent live plugging and unplugging and to avoid accidental operation. Existing locking devices commonly use a locking lever, with a hook at one end that engages with a locking groove on the charging port. Before removing the charging gun, pressing the other end of the locking lever causes the hook to lift, unlocking the device. However, for safety, before unlocking, it is necessary to control the charging station to disconnect the charging circuit via the charging pile, the vehicle's infotainment system, or a mobile phone, and then unlock and remove the charging gun. This presents a cumbersome unlocking process. Utility Model Content

[0003] Based on the above, the purpose of this utility model is to provide a charging gun locking structure that facilitates unlocking the charging gun and ensures charging safety.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A charging gun locking structure includes a charging gun housing and a locking rod. The charging gun housing has a receiving cavity, and a support seat is provided on the cavity wall. The middle part of the locking rod is rotatably connected to the support seat. One end of the locking rod extends out of the gun head end of the charging gun housing and forms a locking hook part, and the other end of the locking rod protrudes from the surface of the charging gun housing and forms a button part.

[0006] An electromagnet is provided in the accommodating cavity and near the locking hook. An armature that cooperates with the electromagnet is provided on the locking rod. The electromagnet is used to attract the armature when energized, so that the locking rod is kept in the locked state and the button part cannot drive the locking rod.

[0007] The surface of the button is covered with a soft rubber layer, and a cavity is provided below the soft rubber layer. A sensing switch is provided in the cavity. The sensing switch is triggered when the button is pressed and the soft rubber layer is deformed. After being triggered, the sensing switch is used to send a signal to the charging pile to cut off the charging circuit and de-energize the electromagnet, so that the button can drive the locking lever to unlock.

[0008] As an alternative, there is a gap between the sensing switch and the soft rubber layer, so that the sensing switch can only be triggered after the soft rubber layer is pressed for a set distance.

[0009] As an alternative, the sensor switch can only be triggered after the soft rubber layer has been pressed and deformed and has been in contact with the sensor switch for a set time.

[0010] As an alternative, a bottom cover is provided on the back of the button, and a spring is provided between the bottom cover and the cavity wall of the receiving cavity. Positioning posts for installing the spring are provided on the bottom cover and the cavity wall of the receiving cavity, respectively.

[0011] As an alternative, a micro switch is provided in the accommodating cavity and near the locking hook. The micro switch is used to be triggered when the locking rod is in the locked state and to send a locking signal back to the charging pile.

[0012] As an alternative, the charging gun housing includes a gun head housing, a handle housing, and a cover plate. The gun head housing and the handle housing are combined to form an installation cavity for passing through the cable, and the handle housing and the cover plate are combined to form a receiving cavity. The installation cavity and the receiving cavity are separated, and the cover plate has a through hole for exposing the button portion.

[0013] The beneficial effects of this utility model are:

[0014] This charging gun locking structure adds an electromagnet, armature, and sensing switch to the existing locking rod structure. The electromagnet and armature work together to keep the locking rod locked, and the button cannot be pressed normally, avoiding accidental operation. The sensing switch is only triggered when there is a clear unlocking operation. After sending a signal to the charging pile to reduce the voltage and current to a safe range and the electromagnet is de-energized and releases the armature, the button can be pressed to unlock, improving safety. In addition, due to the presence of the sensing switch, no additional operation is required to control the charging pile to cut off the charging circuit, making the unlocking process faster and more convenient.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0024] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0026] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] Furthermore, the terms "first" and "second" are merely used to distinguish between different terms in description and do not have any special meaning.

[0028] Please see Figures 1 to 2 As shown, this embodiment provides a charging gun locking structure, including a charging gun housing 1 and a locking rod 2. The charging gun housing 1 is provided with a receiving cavity 11, and a support seat 12 is provided on the cavity wall of the receiving cavity 11. The middle part of the locking rod 2 is rotatably connected to the support seat 12. One end of the locking rod 2 extends out of the gun head end of the charging gun housing 1 and forms a locking hook part 21. The other end of the locking rod 2 protrudes from the surface of the charging gun housing 1 and forms a button part 22.

[0029] An electromagnet 3 is provided in the accommodating cavity 11 and near the locking hook part 21. An armature 4 that cooperates with the electromagnet 3 is provided on the locking rod 2. The electromagnet 3 is used to attract the armature 4 when energized, so that the locking rod 2 remains locked and the button part 22 cannot drive the locking rod 2.

[0030] A soft rubber layer 23 is provided on the surface of the button part 22, and a cavity 24 is provided below the soft rubber layer 23. A sensing switch 25 is provided in the cavity 24. The sensing switch 25 is triggered when the button part 22 is pressed and the soft rubber layer 23 is deformed. The sensing switch 25 is used to send a signal to the charging pile to cut off the charging circuit and de-energize the electromagnet 3 after being triggered, so that the button part 22 can drive the locking rod 2 to unlock.

[0031] Therefore, the cooperation between electromagnet 3 and armature 4 can keep the locking lever 2 locked, and the button 22 cannot be pressed normally, thus avoiding accidental operation. The sensing switch 25 is only triggered when there is a clear unlocking operation. After the voltage and current are reduced to a safe range by sending a signal to the charging pile and the electromagnet 3 is de-energized and releases the armature 4, the button 22 can be pressed to unlock, which improves the safety of use. In addition, due to the presence of the sensing switch 25, there is no need to perform additional operations to control the charging pile to cut off the charging circuit, making the unlocking process faster and more convenient.

[0032] Optionally, there is a gap between the sensing switch 25 and the soft rubber layer 23, so that the sensing switch 25 can only be triggered after the soft rubber layer 23 is pressed for a set distance; or, the sensing switch 25 can only be triggered after the soft rubber layer 23 is pressed and deformed and continues to contact the sensing switch 25 for a set time.

[0033] Whether setting a travel distance, a time limit, or both, the goal is to prevent accidental triggering of the sensing switch 25, which could cause the charging process to stop unexpectedly and ensure normal operation. Furthermore, by pressing the button 22 for a long distance / for an extended period, the intention to unlock is clearly stated, triggering the sensing switch 25 and directly cutting off the charging circuit. This eliminates the possibility of controlling the charging circuit from the charging station or the vehicle's cloud-based system, simplifying the operation.

[0034] Optionally, a bottom cover 26 is provided on the back of the button part 22, and a spring 27 is provided between the bottom cover 26 and the cavity wall of the receiving cavity 11. Positioning posts 28 for installing the spring 27 are respectively provided on the bottom cover 26 and the cavity wall of the receiving cavity 11.

[0035] Therefore, after the spring force of the spring 27 helps to press the button part 22, the locking rod 2 automatically returns to the locked state.

[0036] Optionally, a micro switch 5 is provided in the accommodating cavity 11 and near the locking hook portion 21. The micro switch 5 is used to be triggered when the locking rod 2 is in the locked state and to send a locking signal back to the charging pile.

[0037] Therefore, the position of the locking lever 2 can be detected in real time by the micro switch 5, ensuring that the locking lever 2 moves accurately when locking or unlocking, and timely detection of abnormalities to ensure normal charging status.

[0038] Optionally, the charging gun housing 1 includes a gun head housing 13, a handle housing 14, and a cover plate 15. The gun head housing 13 and the handle housing 14 are combined to form a mounting cavity 16 for passing through a cable. The handle housing 14 and the cover plate 15 are combined to form a receiving cavity 11. The mounting cavity 16 is separated from the receiving cavity 11. The cover plate 15 has a through hole 17 for exposing the button portion 22.

[0039] This isolates the locking rod 2 and related components from the electrical components inside the charging gun housing 1, preventing mutual interference and facilitating inspection and maintenance.

[0040] Specific usage process:

[0041] After the charging gun is reliably connected to the car charging port, the charging pile supplies power to the electromagnet 3. The electromagnet 3 generates magnetic force, which tightly attracts the armature 4 on the locking rod 2. The locking hook 21 is pressed down to maintain the locked state, and the button 22 cannot be pressed normally at this time.

[0042] When it is necessary to stop charging and unlock the charging gun, press the button part 22 continuously. After the soft rubber layer 23 is pressed to the set stroke / set time, the sensing switch 25 is triggered. The sensing switch 25 sends a signal to the charging pile. After the charging pile reduces the voltage and current to a safe range, it disconnects the power supply to the electromagnet 3. The magnetic force of the electromagnet 3 disappears, and the button part 22 can be pressed. By pressing the button part 22 to overcome the elastic force of the spring 27, the locking hook part 21 is lifted, realizing the unlocking function. When the button part 22 is released, under the reset action of the spring 27, the button part 22 is lifted, the locking hook part 21 is lowered, and the electromagnet 3 is powered on again to restore the locking function.

[0043] Specifically, the sensing switch 25 is linked with the button part 22. When the button part 22 is pressed down, the sensing switch 25 sends a signal to the charging pile to cut off the charging circuit, giving the charging system time to reduce voltage and current, and also has a certain emergency stopping charging function.

[0044] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
