Description

Technical Field

[0001] This application relates to the field of automotive charging technology, and in particular to an emergency unlocking device for a charging socket, a charging socket assembly, and a vehicle. Background Technology

[0002] The charging port lock is an important component of new energy vehicles. It locks the charging gun inserted into the car's charging port during charging to prevent accidental detachment and ensure a stable and reliable electrical connection. The charging port lock is typically electrically controlled for locking and unlocking. To prevent unlocking malfunctions in abnormal situations, the industry usually includes an emergency release cable for manual operation by the consumer.

[0003] Currently, the emergency cable for car charging ports on the market is generally integrated with the charging port assembly, meaning one end of the cable is fixed inside the charging port and the other end extends out. However, this integrated configuration, with one end of the cable pre-fixed to the charging port assembly, means the cable can only be threaded from the end accessible to the consumer. This results in limited operating space, poor visibility of the through-holes, blind installation by hand, long manual operation time, and poor ergonomics during assembly, failing to meet the rapid assembly requirements of automotive assembly plants. Furthermore, if the emergency cable malfunctions or is damaged, the entire charging port assembly needs to be removed and replaced, increasing after-sales costs for the consumer.

[0004] Therefore, it is necessary to propose a new technical solution to overcome the shortcomings of existing technologies. Utility Model Content

[0005] Based on this, this application provides an emergency unlocking device for a charging socket, a charging socket assembly, and a vehicle, which can improve the convenience of assembly, facilitate after-sales maintenance, and reduce maintenance costs.

[0006] Therefore, this application adopts the following technical solution: an emergency unlocking device for a charging socket, including an actuator and a pull cord, wherein the actuator can be switched from a locked state to an unlocked state by the force of the pull cord, wherein the emergency unlocking device further includes an unlocking control component linked to the actuator, the pull cord is detachably connected to the unlocking control component, and the pull cord drives the actuator to switch from a locked state to an unlocked state through the unlocking control component.

[0007] In some embodiments, the unlocking actuator is a pivot block that rotates under the tension of the pull cable.

[0008] In some embodiments, the unlocking actuator is a sliding block that slides under the tension of the pull wire.

[0009] In some embodiments, the unlocking actuator has a snap-fit ​​recess, and the end of the pull cable has a snap-fit ​​protrusion, the snap-fit ​​protrusion and the snap-fit ​​recess being detachably fitted together.

[0010] In some embodiments, the snap-fit ​​protrusion comprises a metal cylinder.

[0011] In some embodiments, the snap-fit ​​recess includes a cylindrical groove for receiving the metal cylinder and a wire guide groove communicating with the cylindrical groove.

[0012] In some embodiments, the wire passage is connected to the middle of the cylindrical groove along the axial direction of the cylindrical groove, and both sides of the wire passage are blocked by a baffle plate.

[0013] In some embodiments, the snap-fit ​​recess includes a U-shaped opening communicating with the side of the cylindrical groove, through which the metal cylinder is laterally mounted in the cylindrical groove.

[0014] This application also adopts the following technical solution: a charging socket assembly, installed on a vehicle body, the charging socket assembly including a housing and an emergency unlocking device for the charging socket as described above, wherein the unlocking control is disposed on the outside of the housing, and the pull cable is adapted to be connected to the unlocking control after the housing is assembled on the vehicle body.

The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0032] Please see Figures 1 to 7 As shown, this application provides an emergency unlocking device for a charging socket. The emergency device includes an actuator 1 and a pull cord 2. The actuator 1 can be switched from a locked state to an unlocked state by the force of the pull cord 2. The emergency unlocking device also includes an unlocking control element 3 linked to the actuator 1, and the pull cord 2 is detachably connected to the unlocking control element 3. The pull cord 2 drives the actuator 1 from a locked state to an unlocked state via the unlocking control element 3.

[0033] The actuator 1 is a collection of components capable of locking and unlocking actions, and its specific composition can vary. For example, in some embodiments, the actuator 1 may include a circuit board, a motor, gears, a locking tongue, etc.; in other embodiments, the actuator 1 may include an electric latch, etc. This application does not limit the specific composition of the actuator 1. The actuator 1 can switch between a locked state and an unlocked state. In the locked state, the actuator 1 locks the charging gun plugged into the charging socket, and the charging gun cannot be pulled out; in the unlocked state, the actuator 1 releases the lock on the charging gun, and the charging gun can be pulled out. Under normal use, the actuator 1 is controlled by an electrical signal to switch between the locked and unlocked states; when the electrical signal control malfunctions and the actuator 1 cannot unlock, the consumer manually unlocks the actuator 1 by pulling the cable 2.

[0034] Please see Figure 1 As shown, the actuator 1 is a component of the charging socket 10, which is typically mounted on the side panel near the rear of the vehicle. One end of the pull cable 2 is connected to the charging socket 10, and the other end extends to a position where a consumer can easily pull it by hand. In some embodiments, the pull end of the cable 2 is located inside the trunk. The pull end of the cable 2 may have a pull ring to facilitate the insertion of the consumer's fingers for applying force.

[0035] Please see Figure 4 As shown, in this embodiment, the pull wire 2 includes a core wire 21 and a sleeve 22 sleeved over the core wire 21. The end of the sleeve 22 forms an abutment end 23, and a section of the core wire 21 protrudes beyond the abutment end 23. A locking protrusion 24 is provided at the end of the core wire 21 protruding beyond the abutment end 23. In this embodiment, the locking protrusion 24 comprises a metal cylinder, and the core wire 21 is a steel wire rope connected at approximately the center position on the circumferential side of the metal cylinder. The core wire 21 and the cylindrical locking protrusion 24 are approximately connected to form a hammer shape. Please refer to [further details omitted]. Figure 2 and Figure 3 As shown, the unlocking control member 3 is provided with a snap-fit ​​recess, the snap-fit ​​protrusion 24 cooperates with the snap-fit ​​recess, the abutting end 23 is fixed to the housing 11 of the charging socket 10, and when the pull wire 2 is pulled, the core wire 21 is pulled to move inside the sleeve 22.

[0036] Please see Figures 5 to 7As shown, the unlocking control element 3 is linked to the actuator 1. Linkage means that the movement of the unlocking control element 3 can drive the movement of the actuator 1. In this embodiment, the unlocking control element 3 is a pivot block that rotates under the tension of the pull cable 2. Specifically, the unlocking control element 3 is connected to the housing 11 of the charging socket 10 via a rotating shaft. When the pull cable 2 applies force to the unlocking control element 3, it can pull the unlocking control element 3 to rotate around the rotating shaft. The rotational movement of the unlocking control element 3 causes the actuator 1 to switch from a locked state to an unlocked state. In other embodiments, the unlocking control element 3 is a sliding block that slides under the tension of the pull cable 2.

[0037] Please continue reading. Figures 5 to 7 As shown, the unlocking actuator 3 has a snap-fit ​​recess, and the snap-fit ​​protrusion 24 at the end of the pull cable 2 is detachably fitted with the snap-fit ​​recess. The snap-fit ​​protrusion 24 is a metal cylinder, and the snap-fit ​​recess includes a cylindrical groove 31 for accommodating the metal cylinder, and a wire passage groove 32 communicating with the cylindrical groove 31. Along the axial direction of the cylindrical groove 31, the wire passage groove 32 communicates with the middle of the cylindrical groove 31, and both sides of the wire passage groove 32 are blocked by a baffle plate 321. The baffle plate 321 prevents the cylindrical snap-fit ​​protrusion 24 from disengaging from the cylindrical groove 31 along the axial direction of the cylinder. The snap-fit ​​recess includes a U-shaped opening 33 that communicates with the side of the cylindrical groove 31. During installation, the metal cylinder is installed laterally in the cylindrical groove 31 through the U-shaped opening 33, and the core wire 21 of the pull wire 2 passes through the side opening of the wire groove 32.

[0038] Please refer to it again. Figures 1 to 3 As shown, this application also provides a charging socket assembly. The charging socket assembly is mounted on the vehicle body, specifically, typically on the rear side panel of the vehicle body. The charging socket assembly includes a housing 11 and an emergency unlocking device for the charging socket as described above, wherein the unlocking actuator 3 is disposed on the outside of the housing 11, and the pull cable 2 is adapted to connect to the unlocking actuator 3 after the housing 11 is assembled onto the vehicle body.

[0039] In one embodiment, the assembly process of the charging socket assembly is as follows: The pull cable 2 is removed from the charging socket, forming a relatively independent component; the charging socket is installed on a preset position on the vehicle body sheet metal; one end of the pull cable 2 with the snap-fit ​​protrusion 24 is threaded from the rear wheel arch inside the vehicle to the outside, and snapped into the snap-fit ​​recess of the unlocking control 3, thus completing the assembly. It should be noted that the assembly process described here is merely exemplary. Since the pull cable 2 is an independent component in this application, the placement direction, angle, and twisting state of the pull cable 2 are less restricted during installation, allowing the operator to install the pull cable 2 in the most convenient posture. Furthermore, since the pull cable 2 is an independent component, the installation of the charging socket 10 is greatly facilitated because the long pull cable 2 does not need to be dragged along.

[0040] As described above in the specific embodiments, the emergency unlocking device for a charging socket provided in this application includes a pull cable 2, an actuator 1, and an unlocking control component 3 linked to the actuator 1. The pull cable 2 is detachably connected to the unlocking control component 3. The pull cable 2 drives the actuator 1 to switch from a locked state to an unlocked state through the unlocking control component 3. This arrangement allows the charging socket 10 and the pull cable 2 to be installed independently without affecting each other. Furthermore, the pull cable 2 can be threaded from different directions as needed, greatly improving the convenience of assembly. Moreover, if the pull cable 2 is damaged, it can be removed and replaced separately, facilitating after-sales maintenance and reducing maintenance costs. In the emergency unlocking device for a charging socket and the charging socket assembly having it provided in this application, the pull cable 2 and the actuator 1 are easy to disassemble and install. Furthermore, for different vehicle models, the pull cable 2 of different lengths can be replaced while keeping the overall charging socket 10 unchanged, demonstrating good adaptability and versatility.

[0041] This application also provides a vehicle that includes the charging socket assembly described above. The vehicle provided by this application, having the aforementioned charging socket assembly, also possesses the aforementioned beneficial effects.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
