[0008] DE 11 2013 006 082 T5 discloses an actuator. EXPLANATION OF THE REVELATION / INVENTION

[0009] One aspect of the present disclosure provides a device for emergency disconnection (e.g., for emergency disconnection, e.g., for disconnection in an emergency) of a battery charging inlet of an electric vehicle for emergency disconnection of the outlet coupled to the inlet.

[0010] In particular, the present invention provides a device for emergency disconnection of a battery charging inlet of an electric vehicle according to claim 1 and a charging inlet of a vehicle according to claim 4.

[0011] A device for emergency disconnection of a battery charging inlet of an electric vehicle according to one aspect of the present disclosure comprises a housing, a handle which is mounted in the housing and which is rotatable by partial exposure through a groove (e.g. a hole) formed at (e.g. on) one side of the housing, and an emergency disconnect cable (e.g. an emergency disconnect cable pull) which has one side (e.g. a first side, one end, a first end) which is connected to the handle, and which has another side (e.g. a second side, one other end, a second end) which is connected to an emergency disconnect lever which is provided in an inlet actuator which is mounted on the inlet for charging an electric vehicle.

[0012] Then, when the handle is turned, the emergency release rope is pulled (e.g., the emergency release rope is pulled) and the emergency release rope turns (in doing so) the emergency release lever to release (e.g., to free) the restraint of the outlet that is coupled to the inlet.

[0013] Furthermore, when the emergency release lever is turned by means of the emergency release rope, (then) a protrusion (e.g. a protrusion, e.g. a protrusion) of an actuator pin (e.g. an actuator pin), which protrudes downwards (towards) in order to lock (e.g. to lock) the outlet by means of the inlet actuator by means of pressing, is released (e.g. released).

[0014] The handle then returns to its (e.g., its) starting position by means of an elastic restoring force when an external force is released after it has been rotated.

[0015] Furthermore, a handle mounting part, which protrudes in a frame shape (e.g., which protrudes in a frame shape) having a diameter smaller (e.g., larger) than that of the handle, is formed on (e.g., on) the inside of the housing. The handle is inserted into the handle mounting part and rotated in the handle mounting part, and after actuation, the handle returns by means of a plate spring provided in the handle mounting part.

[0016] Furthermore, the diaphragm spring has one side (e.g., one end) which is fixed and coupled to a diaphragm spring mounting groove formed in the handle mounting part, and has the other side (e.g., the other end) which is inserted into a coupling groove formed on a diaphragm spring coupling part, which is designed to protrude from the handle (e.g., to protrude from the handle), so that the (e.g., a) displacement occurs as a result of the rotation of the handle.

[0017] Furthermore, a handle attachment end is formed at (e.g. on) one side of the emergency release rope and the handle attachment end is coupled to one side of the circumference of the handle, so that the handle attachment end is pulled along the direction of rotation of the handle as a result of the rotation of the handle.

[0018] According to the device for emergency disconnection of the battery charging inlet of the electric vehicle according to the present disclosure / invention, it is possible for a user to easily disconnect the actuator pin of the inlet actuator by means of the emergency disconnect cable by means of the handle actuation and thereby easily disconnect the outlet in an emergency.

[0019] Furthermore, it is possible to automatically return the emergency release rope to its (e.g.) starting position after the outlet is / is separated by operating the handle.

Fig. Figure 2 is an enlarged representation of section A from Fig. 1. Fig. Figure 3 is a representation showing section A as a result of actuating the device for emergency disconnecting the battery charging inlet of the electric vehicle according to the present disclosure / invention. FIGS. 4 to 6 are partial exploded views of the internal configuration of the device for emergency disconnection of the battery charging inlet of the electric vehicle according to the present disclosure / invention. FIGS. 7 and 8 are projection representations to explain the actuation of the device for emergency disconnection of the battery charging inlet of the electric vehicle according to the present disclosure / invention. DESCRIPTION OF EXECUTION FORMS

[0020] In order to fully understand the present disclosure / invention, its operational advantages and the objectives achieved by applying the present disclosure / invention, reference should be made to the accompanying drawings, which illustrate the preferred embodiments of the present disclosure / invention by way of example, and to the contents shown in the accompanying drawings.

[0021] When describing the preferred embodiments of the present disclosure / invention, descriptions of known or repeated descriptions which may unnecessarily obscure the subject matter of the present disclosure / invention are reduced or omitted.

[0022] Fig. Figure 1 is a representation which depicts a device for emergency disconnection of a battery charging inlet of an electric vehicle according to the present disclosure / invention, Fig. Figure 2 is an enlarged representation of section A from Fig. 1, and Fig. Figure 3 is a representation showing section A as a result of actuation (e.g. after actuation) of the device for emergency disconnection of the battery charging inlet of the electric vehicle according to the present disclosure / invention.

[0023] Referring to FIGS. 1 and 2, fastening and locking means, as shown in FIGS. 1 and 2, can be provided therein to provide stability of the coupling (e.g. the coupling state) between the inlet and the outlet.

[0024] An outlet or charging plug 20 has a locking end 21 formed on it. An inlet or charging inlet (e.g., a battery charging inlet) 30 has a locking projection 31 such that the locking end 21 is locked or engages with the locking projection 31 to prevent the outlet from retracting in a reverse direction (e.g., a retraction direction) when the outlet 20 is attached to or engaged with the inlet 30. Furthermore, to provide physical security thereof, an actuator pin 11 projects downwards to press against the locking end 21 of the outlet 20 by actuating an inlet actuator 10 provided in the inlet 30.

[0025] When an outlet disconnect lever 22, which is integrally formed with the locking end 21, is pressed to disconnect the coupling (e.g. the coupling state) of the outlet 20, the locking end 21 pushes the actuator pin 11 upwards by rotating it about a rotation axis to allow the outlet 20 to withdraw from the inlet (e.g., that the outlet 20 is withdrawn from the inlet).

[0026] The outlet should be quickly disconnected for emergency situations such as theft, emergencies, and security concerns. However, if a malfunction of the inlet actuator or similar occurs, it is possible that the outlet will not disconnect correctly (e.g., adequately).

[0027] The following describes a device for the emergency disconnection of a battery charging inlet of an electric vehicle according to an embodiment of the present disclosure / invention with reference to FIGS. 1 to 3.

[0028] A device for emergency disconnection of a battery charging inlet of an electric vehicle according to the present disclosure / invention is a device for emergency disconnection of the coupling (e.g. the coupling state) in a state in which the inlet 30, configured in an electric vehicle, and the outlet 20 have been connected for charging.

[0029] The inlet 30 and the outlet 20 are coupled to be electrically connected to each other, and after fastening or engaging, the locking end 21, which is formed at the outlet 20, is / is locked by means of the locking projection 31, which is formed at the inlet 30, to prevent the charging plug 20 from moving in the reverse direction (e.g. the retraction direction).

[0030] Furthermore, for the physical safety thereof, the actuator pin 11 is projecting downwards (e.g., the actuator pin 11 protrudes downwards) in order to lock the locking end 21 of the outlet 20 by pressing (e.g., to press (on) the locking end 21 of the outlet 20 in order to lock it) by actuating the inlet actuator 10, which is provided in the inlet 30.

[0031] In embodiments, when the outlet disconnect lever 22, which is integrally formed with the locking end 21, is pressed to disconnect the coupling (e.g. the coupling state) of the outlet 20, the locking end 21 pushes the actuator pin 11 upwards by rotating it about an axis of rotation to retract the outlet 20.

[0032] In embodiments, the emergency disconnect lever 12 is provided in the inlet actuator 10 for emergency disconnection of the outlet 20 and the inlet 30, as shown in Fig. 2 shown. If the emergency release lever 12 is as shown in Fig. 3 shown is rotated, (then) the actuator pin 11 is moved to no longer press (e.g. further) the locking end 21 of the outlet 20 (e.g. to no longer press on the locking end 21 of the outlet 20).

[0033] The rotary actuation of the emergency release lever 12 is actuated by pulling an emergency release rope (e.g. an emergency release rope pull) 140 which is connected to it, and a handle 120 is provided for pulling the emergency release rope 140 (e.g. to pull on the emergency release rope 140).

[0034] Referring to FIGS. 4 to 6, the handle 120 of the device for emergency disconnection of the battery charging inlet of the electric vehicle of the present disclosure / invention is coupled to a housing 110 and points to a plate spring or a spiral torsion spring (e.g. a spiral spring) 130, an emergency disconnect cable (e.g. an emergency disconnect cable pull) 140 and a cable line (e.g. a cable guide line, e.g. a cable tube, e.g. a cable pull line, e.g. a cable pull guide line) 150 for covering and protecting the emergency disconnect cable 140.

[0035] As in Fig. As shown in Figure 4, in embodiments the housing 110 has two pieces (e.g., two separate pieces, e.g., two parts, e.g., two separate parts) which is arranged to be separated and assembled, and has a handle mounting part 111 which projects in a frame shape (e.g., which projects in a frame shape) which has a diameter that is smaller (e.g., larger) than the diameter of the handle 120 which is formed in a cavity of a side housing (e.g., a one-sided housing, e.g., a housing side), and the handle 120 is / is inserted into the handle mounting part 111 in order to be rotatable in the handle mounting part 111.

[0036] The other side housing (e.g. the other side housing, e.g. the other housing side) has a hole for the handle 120 to protrude towards the outside of the housing (e.g. so that the handle 120 can protrude towards the outside of the housing).

[0037] In embodiments, a plate spring mounting groove 112 is formed in the handle mounting part 111, such that one side (e.g., one end) of a plate spring 130 is inserted into and fastened to the plate spring mounting groove 112.

[0038] The plate spring 130 is arranged within the inner circumference of the handle 120 and its overall diameter is smaller than the inner diameter of the handle 120 and the other side (e.g. the other end) of the plate spring 130 is coupled to the handle 120.

[0039] For this purpose, a diaphragm spring coupling part 121 is formed to project from the handle 120 (her) as shown (e.g., to project from the handle 120 (her)), and the diaphragm spring 130 (e.g., the other side of the diaphragm spring 130) is inserted into and coupled to a coupling groove formed in the diaphragm spring coupling part 121.

[0040] In embodiments, when the handle 120 is rotated, the diaphragm spring 130 is also compressed and displaced, and when the external force applied to the handle 120 is released, the diaphragm spring 130 returns to its initial state (e.g., to its original state, to its initial position) by means of the elastic restoring force, so that the handle 120 is again arranged in its initial position.

[0041] The emergency release rope 140 has one end (e.g., one end) connected to the handle 120, and the other end (e.g., the other end) connected to the emergency release lever 12, so that when the emergency release rope 140 is pulled by means of the handle (e.g., when the emergency release rope 140 is pulled by means of the handle), the emergency release rope 140 then pulls the emergency release lever 12 so that it rotates (e.g., the emergency release rope 140 then pulls the emergency release lever 12 so that it rotates).

[0042] One end (e.g., an end piece) 141 of the rope 140 is attached to the handle 120 side (e.g., to the side of the handle 120, e.g., to the side of the rope 140 facing the handle 120). The end 141 is connected to a section of the circumference (e.g., the outer circumference) of the handle 120.

[0043] If the handle 120 is in a condition that is in Fig. 7 is shown, in a state that is in Fig. As shown in Figure 8, the plate spring 130 is compressed and deformed, and the end 141 is rotated along the direction of rotation of the handle 120, so that the emergency release rope 140 (e.g., on the emergency release rope 140) is pulled.

[0044] A hook (e.g. an eyelet) 142 is formed at (e.g. on) the other side (e.g. the other end) of the emergency release rope 140, so that the hook 142 is coupled by being hooked (e.g. attached) to the emergency release hook 12.

[0045] As described above, the device for emergency disconnection of the battery charging inlet of the electric vehicle (according to) the present disclosure / invention can simply actuate the emergency disconnect lever of the inlet actuator to release (e.g., release) the outlet holding state of the actuator pin by actuating the emergency disconnect lever, and thereby simply disconnect the coupling (e.g., the coupling state) of the inlet and the outlet.

[0046] In some embodiments, a vehicle has a battery charging inlet that engages with a battery charging plug. A locking mechanism is provided to secure (e.g., ensure) the engagement of the inlet and the plug. For emergency situations, the inlet has a disconnect-release mechanism (e.g., a disconnect-activate mechanism). In some embodiments, the inlet has an actuator with an actuator pin capable of moving toward the locking mechanism to secure the engagement of the outlet or plug and the inlet. The inlet also has a lever, a cable (e.g., a pull cord), and a handle, which are components of the disconnect-release mechanism. The cable has one end connected to the lever and the other end connected to the handle.The handle is held in a housing along with a spring, which exerts an elastic force on the handle. When the handle rotates, the rope is pulled (e.g., the rope is pulled), and the handle rotates to move the actuator pin.
