Description

Technical Field

[0001] This application belongs to the field of vehicle charging technology, specifically relating to a charging gun lock, a charging base assembly, and a vehicle. Background Technology

[0002] With the rise of new energy vehicles in China, electric vehicles are highly sought after by consumers, and slow charging is the most cost-effective method. However, during slow charging, various reasons can cause the automatic unlocking of the slow charging electronic lock to fail, making it impossible to remove the charging gun. Therefore, an emergency unlocking is required before the charging gun can be removed. However, current emergency unlocking technology generally uses a pull cable located in the trunk for manual unlocking. This emergency unlocking mechanism is not only complex and bulky, but also difficult to find and inconvenient to operate. Utility Model Content

[0003] The purpose of this utility model is to provide a charging gun lock, a charging base assembly, and a vehicle. This charging gun lock can not only lock and unlock the charging gun normally, but also make it very convenient for users to unlock the charging gun in an emergency.

[0004] The first aspect of this utility model discloses a charging gun lock, comprising: a lock shell, a latch, an electromagnetic circuit, and an elastic reset member. The lock shell has a mounting cavity. The latch is slidably connected to the lock shell, with one end extending through the mounting cavity. The electromagnetic circuit includes a telescopic electromagnet, a controller, and an emergency unlocking switch connected in series via wires. The controller controls the on / off state of the electromagnetic circuit. The emergency unlocking switch is electrically connected between the controller and the telescopic electromagnet and controls the on / off state of the electromagnetic circuit. The telescopic electromagnet is located within the mounting cavity and is kinetically connected to the latch. When the electromagnetic circuit is in a closed loop, the telescopic electromagnet drives the latch to extend outside the mounting cavity, thereby locking the latch with the charging gun. The elastic reset member is sleeved on the latch and located within the mounting cavity. When the latch is locked with the charging gun, the elastic reset member is in an elastically compressed state and can recover its elastic deformation when the electromagnetic circuit is open, driving the latch to retract into the mounting cavity, thereby unlocking the latch from the charging gun.

[0005] In one exemplary embodiment, the resilient reset member includes a spring that is sleeved on the latch and located within the mounting cavity.

[0006] In one exemplary embodiment, the latch includes a positioning post and a limiting part. The limiting part is located between the positioning post and the telescopic electromagnet along the axial direction of the positioning post and is throttle-connected to the telescopic electromagnet. The elastic reset member is sleeved on the positioning post and located between the limiting part and the lock housing.

[0007] In one exemplary embodiment, the telescopic electromagnet is provided with a slot, and the limiting part has a claw, which engages with the slot.

[0008] In one exemplary embodiment, the limiting part has a plurality of claws spaced apart from each other; the slot is an annular groove arranged around the axial direction of the positioning post; each claw is engaged in the slot, and the distance between two adjacent claws is equal.

[0009] In one exemplary embodiment, the telescopic electromagnet is further provided with a positioning groove, the positioning groove and the slot are spaced apart from each other, the limiting part is further provided with a protrusion, the protrusion and the claw are spaced apart from each other, and the protrusion passes through the positioning groove along the axial direction of the positioning post.

[0010] The second aspect of this utility model discloses a charging base assembly, including a charging base and the aforementioned charging gun lock, wherein the charging gun lock is connected to the charging base.

[0011] In one exemplary embodiment, the charging dock includes an outer surface facing the charging gun, and the emergency unlock switch is disposed on the outer surface of the charging dock.

[0012] The third aspect of this utility model discloses a vehicle, including a charging gun and the aforementioned charging socket assembly, wherein the charging gun and the charging socket are detachably connected.

[0013] In one exemplary embodiment, the charging gun is provided with a lock hole. When the charging gun is connected to the charging base, the locking tongue passes through the lock hole and positions the charging gun on the charging base.

[0014] The present invention has the following beneficial effects: In this invention, when a vehicle needs charging, the charging gun is inserted into the charging socket. The controller activates the entire electromagnetic circuit, causing the telescopic electromagnet to generate magnetic force, pushing its movable iron core out of the mounting cavity. This, in turn, pushes the locking tongue out of the mounting cavity, locking the charging gun and allowing charging to proceed. After charging is finished, the controller disconnects the entire electromagnetic circuit, the electromagnet's magnetic force disappears, and the stored elastic potential energy is released through the elastic reset component. This, in turn, pushes the movable iron core of the telescopic electromagnet back to its original position against the locking tongue, allowing the charging gun to be safely removed. If the charging gun cannot be removed, the electromagnetic circuit can be disconnected via the emergency unlock switch. In this case, the telescopic electromagnet's magnetic force disappears, the stored elastic potential energy is released through the elastic reset component, and this, in turn, pushes the movable iron core of the telescopic electromagnet back to its original position against the locking tongue, allowing the charging gun to be safely removed. Therefore, this charging gun lock not only enables normal locking and unlocking of the charging gun but also allows users to conveniently unlock it in an emergency.

[0027] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present application, and should not be construed as limiting the present application.

[0028] This embodiment provides a charging gun lock 10. The charging gun lock 10 is used to lock the charging gun to the charging dock when it is charging on the vehicle's charging dock, and can automatically unlock the charging gun after power is cut off. If the charging gun lock 10 fails to automatically unlock the charging gun after power is cut off, the charging gun lock 10 can be unlocked via an emergency unlock switch 15.

[0029] Combination Figures 1 to 7 As shown, the charging gun lock 10 includes a lock housing 11, a latch 12, an electromagnetic circuit, and a resilient reset member 16. The lock housing 11 has a mounting cavity 101. The latch 12 is slidably connected to the lock housing 11, with one end passing through the mounting cavity 101. The electromagnetic circuit includes a telescopic electromagnet 13 connected in series with a wire, a controller 14, and an emergency unlocking switch 15. The controller 14 controls the on / off state of the electromagnetic circuit. The emergency unlocking switch 15 is electrically connected between the controller 14 and the telescopic electromagnet 13 and can control the on / off state of the electromagnetic circuit. The telescopic electromagnet 13... 3. Located inside the mounting cavity 101, the telescopic electromagnet 13 is connected to the locking tongue 12 and can drive the locking tongue 12 to extend outside the mounting cavity 101 when the electromagnetic circuit is open, so that the locking tongue 12 locks with the charging gun; the elastic reset member 16 is sleeved on the locking tongue 12 and located inside the mounting cavity 101. When the locking tongue 12 is locked with the charging gun, the elastic reset member 16 is in an elastic compression state, and can restore elastic deformation when the electromagnetic circuit is open, and drive the locking tongue 12 to retract into the mounting cavity 101, so that the locking tongue 12 unlocks with the charging gun.

[0030] For example, the lock housing 11 is provided with a guide hole that connects the inside and outside of the mounting cavity 101. The lock tongue 12 passes through the guide hole and can slide along the hole wall of the guide hole.

[0031] For example, the telescopic electromagnet 13 and the locking tongue 12 are engaged. During the movement of the telescopic electromagnet 13, the locking tongue 12 is driven to move synchronously, thereby realizing the transmission connection between the telescopic electromagnet 13 and the locking tongue 12.

[0032] In this invention, when the vehicle needs charging, after the charging gun is inserted into the charging socket, the controller 14 activates the entire electromagnetic circuit, causing the telescopic electromagnet 13 to generate magnetic force, which pushes the movable iron core 131 of the telescopic electromagnet 13 to move, thereby pushing the locking tongue 12 out of the mounting cavity 101 to lock the charging gun, thus enabling charging. After the owner finishes charging, the controller 14 disconnects the entire electromagnetic circuit, the electromagnet's magnetic force disappears, and the stored elastic potential energy is released through the elastic reset member 16, which in turn pushes the movable iron core of the telescopic electromagnet 13 and the locking tongue 12 back to reset, allowing the charging gun to be safely removed. If the charging gun cannot be removed, the electromagnetic circuit can be disconnected through the emergency unlocking switch 15; at this time, the magnetic force of the telescopic electromagnet 13 disappears, the stored elastic potential energy is released through the elastic reset member 16, which in turn pushes the movable iron core of the telescopic electromagnet 13 and the locking tongue 12 back to reset, allowing the charging gun to be safely removed. Therefore, the charging gun lock 10 can not only lock and unlock the charging gun normally, but also allow users to easily unlock the charging gun in an emergency.

[0033] In this embodiment, the elastic reset member 16 includes a spring to achieve the reset of the latch 12 at low cost. The spring is sleeved on the latch 12 and gradually compressed as the latch 12 extends outward toward the mounting cavity 101. Of course, in other embodiments, the elastic reset member 16 can also be a hydraulic rod.

[0034] It should be understood that one end of the spring abuts against the lock housing 11, and the other end abuts against the latch 12. The axial direction of the spring is the same as the extension / retraction direction of the latch 12.

[0035] Furthermore, the locking tongue 12 includes a positioning post 121 and a limiting part 122. The limiting part 122 is located between the positioning post 121 and the telescopic electromagnet 13 along the axial direction of the positioning post 121 and is connected to the telescopic electromagnet 13 in a transmission manner. The spring is sleeved on the positioning post 121 and is located between the limiting part 122 and the lock housing 11 (that is, the inner wall of the mounting cavity 101).

[0036] For example, the limiting part 122 is disc-shaped, and the positioning post 121 is cylindrical. The positioning post 121 and the limiting part 122 are coaxially arranged, and the diameter of the limiting part 122 is larger than the diameter of the positioning post 121. The diameter of the spring is smaller than the diameter of the limiting part 122. Therefore, when the spring is fitted onto the positioning post 121, one end of the spring abuts against the limiting part 122, and the other end of the spring abuts against the lock housing 11 (i.e., the inner wall of the mounting cavity 101).

[0037] It should be understood that when the spring is sleeved on the positioning post 121 and located between the limiting part 122 and the lock housing 11, the spring can stably extend and retract under the guidance of the positioning post 121 and the limitation of the limiting part 122.

[0038] In this embodiment, the telescopic electromagnet 13 includes a magnetic housing, a coil winding, and a movable iron core 131. The coil winding, controller 14, and emergency unlocking switch 15 are connected in series to form an electromagnetic circuit. The coil winding is located inside the magnetic housing, which has a guide hole that extends through one end of the magnetic housing. The movable iron core 131 is located inside the guide hole and can move along the axial direction of the guide hole to the outside of the magnetic housing to drive the locking tongue 12 to move.

[0039] It should be understood that after the coil winding is energized, that is, after the entire electromagnetic circuit is closed and energized, the movable iron core 131 will push the locking tongue 12 out of the mounting cavity 101 under the action of the guide hole and the coil winding. When the coil winding is de-energized by the controller 14 or the emergency unlocking switch 15, the elastic reset member 16 can push the locking tongue 12 to the position separated from the charging gun by the deformation restoring force, that is, to the position where it can be unlocked from the charging gun and detached from the charging base.

[0040] Combination Figures 5 to 7 As shown, the movable iron core 131 of the telescopic electromagnet 13 is provided with a slot 102, and the limiting part 122 has a claw 1221. The claw 1221 is engaged in the slot 102 so that the locking tongue 12 can move synchronously with the movable iron core 131.

[0041] Furthermore, the limiting part 122 has a plurality of claws 1221 arranged at intervals; the slot 102 is an annular groove arranged around the axial direction of the positioning post 121; each claw 1221 is engaged in the slot 102, and the distance between two adjacent claws 1221 is equal, so as to ensure the connection between the locking tongue 12 and the movable iron core 131 is firm, and also to ensure that the locking tongue 12 and the movable iron core 131 are subjected to uniform force.

[0042] For example, the movable iron core 131 is coaxially arranged with the positioning post 121, and the slot 102 is arranged around the axial direction of the movable iron core 131 on the peripheral side of the movable iron core 131.

[0043] Furthermore, combined Figure 5and Figure 7 As shown, the peripheral side of the movable iron core 131 of the telescopic electromagnet 13 is also provided with a positioning groove 103. The positioning groove 103 is spaced apart from the slot 102, and the positioning groove 103 passes through the end face of the movable iron core 131 along the axial direction of the movable iron core 131. The limiting part 122 also has a protrusion 1222, which passes through the positioning groove 103 along the axial direction of the positioning post 121, so as to play a positioning role when the locking tongue 12 is installed with the movable iron core 131, and after the locking tongue 12 is installed with the movable iron core 131, it can also restrict the horizontal movement of the locking tongue 12 relative to the movable iron core 131.

[0044] This embodiment also provides a charging dock assembly, including a charging dock and the aforementioned charging gun lock 10, wherein the charging gun lock 10 is connected to the charging dock.

[0045] For example, a charging dock is a slow charging dock for vehicles. For instance, a charging dock for a 7kW charging gun.

[0046] Furthermore, the charging base includes an outer surface facing the charging gun, and an emergency unlocking switch 15 is disposed on the outer surface of the charging base.

[0047] It should be understood that the outer surface of the charging gun refers to the surface of the charging base exposed after the charging port cover is opened, that is, the surface of the charging base that the user can touch after the charging port cover is opened.

[0048] This embodiment also provides a vehicle, including a charging gun and the above-mentioned charging socket assembly, wherein the charging gun and the charging socket are detachably connected.

[0049] Furthermore, the charging gun is provided with a lock hole. When the charging gun is connected to the charging base, the locking tongue 12 passes through the lock hole and positions the charging gun on the charging base.

[0050] For example, the locking hole of the charging gun can be located on the side of the charging gun (e.g., on a surface perpendicular to the vehicle's wheelbase direction after the charging gun is inserted into the charging socket). In this case, when the charging gun is inserted into the charging socket (e.g., the direction of insertion is the vehicle's track direction), the charging socket can limit the charging gun's vertical (vehicle height direction) and horizontal (vehicle track direction) directions, while the charging gun's front-to-back direction (vehicle track direction, i.e., the direction in which the charging gun is pulled out) can be limited by the locking tongue 12 passing through the locking hole.

[0051] In this invention, when the vehicle needs charging, after the charging gun is inserted into the charging socket, the controller 14 activates the entire electromagnetic circuit, causing the telescopic electromagnet 13 to generate magnetic force, which pushes the movable iron core 131 of the telescopic electromagnet 13 to move, thereby pushing the locking tongue 12 out of the mounting cavity 101 to lock the charging gun, thus enabling charging. After the owner finishes charging, the controller 14 disconnects the entire electromagnetic circuit, the electromagnet's magnetic force disappears, and the stored elastic potential energy is released through the elastic reset member 16, which in turn pushes the movable iron core of the telescopic electromagnet 13 and the locking tongue 12 back to reset, allowing the charging gun to be safely removed. If the charging gun cannot be removed, the electromagnetic circuit can be disconnected through the emergency unlocking switch 15; at this time, the magnetic force of the telescopic electromagnet 13 disappears, the stored elastic potential energy is released through the elastic reset member 16, which in turn pushes the movable iron core of the telescopic electromagnet 13 and the locking tongue 12 back to reset, allowing the charging gun to be safely removed.

[0052] In summary, the charging gun lock 10 not only enables normal locking and unlocking of the charging gun, but also allows users to easily unlock the charging gun in emergencies, especially in urgent situations, enabling faster, more convenient, and safer manual unlocking of slow charging guns. Furthermore, the charging gun lock 10 replaces the original steel wire emergency cable, resulting in lower cost and lighter weight.
