Description

Unlocking device

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an unlocking device, and more particularly, to an unlocking device for manually releasing a locked state of an actuator.

The actuator generates the forward/backward motion of the latch, thereby performing various functions. A specific part may be locked by the latch of the actuator, but the actuator will not operate and thus the lock of the specific part may not be released. In such an emergency situation, it is necessary for the operator to manually operate the latch of the actuator. For this purpose, an unlocking device is used.

For example, an electric vehicle has a socket for charging, and the charging connector of the charger is coupled to the socket to charge the battery. Since the charging connector should not be separated from the charging socket of the vehicle during the charging process, an actuator is used to lock the charging connector in a state in which it is coupled to the socket.

However, even though charging is completed, there are cases in which the actuator does not operate for some reason, so that the charging connector cannot be separated from the socket. In such an emergency situation, it is necessary to manually operate the latch of the actuator.

In addition, in describing the components of the embodiment of the present invention, terms such as first, second, A, B, (a), (b), etc. may be used. These terms are only for distinguishing the components from other components, and the essence, order, or order of the components are not limited by the terms. When it is described that a component is “connected”, “coupled” or “connected” to another component, the component may be directly connected or connected to the other component, but another component is between each component. It will be understood that may also be "connected", "coupled" or "connected".

As shown in the drawings, the cable 10 has an inner wire 12 therein, and a covering portion 14 to surround the inner wire 12 . The inner wire 12 is preferably made of a material with good rigidity, and is generally made of a metal material. The covering portion 14 serves to protect the inner wire 12 . Both ends of the inner wire 12 protrude more than the covering portion 14 . One end of the inner wire 12 is connected to the actuator side, and the other end is connected to the pull handle 20 through a connection block 19 to be described below.

In order for the inner wire 12 to be movable relative to the covering portion 14 , an end hook 16 is provided at one end of the covering portion 14 . The end hook 16 is connected to and fixed to the end of the covering portion 14 . The inner wire 12 passes through the end hanger 16 . A hook groove 18 is formed around the outer surface of the tip of the end hook 16 . There is a step portion 18 ′ surrounding the outer surface of the rear end of the end hanger 16 . The hook groove 18 and the stepped portion 18 ′ are configured to fix the end hook 16 , and are parts to be hung on the hook fixing part 34 to be described below.

There is a connection block 19 at the end of the inner wire 12 on the side where the end hanger 16 is located. The connecting block 19 is made of a metal material and is integrally coupled to the end of the inner wire 12 . A pulling handle 20 to be described below is integrally coupled to the other end of the connection block 19 . The connection block 19 interferes with the holder 28 so that it does not immediately come off the holder 28 even when the pull handle 20 is pulled upward from the holder 28 to be described below.

A pull handle 20 is integrally coupled to the connection block 19 . The pulling handle 20 is composed of a ring wire 22 and a handle tube 24 surrounding the ring wire 22 for a certain section. The ring wire 22 is configured to form a closed curve. The ring wire 22 may be made of the same material as the inner wire 12 . The handle tube 24 is movable relative to the ring wire 22 . That is, in FIG. 3 , the ring wire 22 of the same length is exposed from the connection block 19 to both sides of the handle tube 24 . When the handle tube 24 moves relative to the ring wire 22 , The length at which the ring wire 22 is exposed is different from each other.

The handle tube 24 is made of a flexible material. The handle tube 24 surrounds only a part of the ring wire 22, as can be seen in FIG. 3 . The handle tube 24 is made of metal and makes it easy for the operator to apply force to the ring wire 22 having a relatively small diameter. The handle tube 24 has a relatively larger diameter compared to the cross-sectional diameter of the ring wire 22 so that it can be in close contact with the inner surface of the seating through-portion 30 of the holder 28 to be described below. That is, the outer diameter of the handle tube 24 is made slightly larger than the inner diameter of the seating through portion 30 . Of course, even if the inner diameter of the seat through portion 30 and the outer diameter of the handle tube 24 are the same, it does not matter if the surface friction force of the seat through portion 30 or the handle tube 24 is large.

On the other hand, the cradle 28 on which the pull handle 20 is mounted is located on one side of the frame 26 . The frame 26 constitutes the exterior of a specific module used in, for example, an automobile. The frame 26 is a kind of fixing part to which the pulling handle 20 is fixed. The cradle 28 may be integrally formed with the frame 26 or may be separately made and installed on the frame 26 .

As shown in FIGS. 2 and 4 , the cradle 28 has a substantially plate shape, and is formed by passing through the seating through portions 30 on both sides. The mounting through-portion 30 is formed symmetrically when two side by side view the holder 28 in a plan view. An entrance 32 is formed on one side of the seating through-portion 30 . The handle tube 24 of the pulling handle 20 enters and exits the seating through-port 30 through the doorway 32 . The inner diameter of the seating through portion 30 is the same as or smaller than the outer diameter of the handle tube 24 as described above. The width of the doorway 32 is smaller than the outer diameter of the handle tube 24 and larger than the outer diameter of the ring wire 22 . Therefore, it is impossible or very large force is required for the handle tube 24 to enter the seating through-hole 30 through the doorway 32 and exit from the seating through-section 30 .

Therefore, it is preferable to allow the hook wire 22 to pass through the doorway 32 rather than the handle tube 24 to pass through the doorway 32 in order to naturally hang the pull handle 20 on the holder 28 and exit. That is, by pulling the pull handle 20 so that the part of the hook wire 22 exposed adjacent to the connection block 19 rather than the part of the handle tube 24 in the pull handle 20 passes through the doorway 32 , It is to move the pull handle 20 so that the hook wire 22 part passes through the doorway 32 in a state where the connection block 19 is relatively adjacent to the holder 28 .

In order to fix the end hanger 16 , the frame 26 has a hanger fixing part 34 . The hook fixing part 34 may also be made integrally with the frame 26 like the holder 28 or may be made separately and installed on the frame 26 .

The first fixing plate 36 and the second fixing plate 36 ′ are side by side on the hook fixing part 34 . A hook 37 protrudes between the inner surfaces of the first fixing plate 36 and the second fixing plate 36 ′ and between them. The hook 37 is located in the hook groove 18 of the end hook 16 so that the end hook 16 is not moved in the front and rear direction of the end hook 16 in the hook fixing part 34. do not

The first fixing plate 36 and the second fixing plate 36 ′ also have stop tucks 38 . The stop tuck 38 is spaced a predetermined distance from the clasp 37 . The step portion 18 ′ is hung on the stop tuck 38 . The stop tuck 38 serves to block the end hanger 16 from moving in the opposite direction of the hanger protrusion 37 .

There are fastening jaws 39 on the outer surfaces of the first fixing plate 36 and the second fixing plate 36 ′. The fastening jaw 39 is for fastening the fixing part cover 40 to be described below. The fastening jaws 39 are formed in two pieces on one fixing plate 36 and 36' in this embodiment. However, the number may vary according to design conditions.

The fixing part cover is coupled to the first fixing plate 36 and the second fixing plate 36' to prevent the end hook 16 located between the first fixing plate 36 and the second fixing plate 36' from falling out. There is (40). The configuration of the fixing part cover 40 is well illustrated in FIG. 5 . The fixing part cover 40 has fastening pieces 43 formed on both sides of the plate-shaped cover body 41 in the width direction, respectively. The fastening piece 43 is elastically deformable and is hung on the fastening jaw 39 . The fastening piece 43 has a fastening hole 45 in which the fastening jaw 39 is located. The number of the fastening pieces 43 is the same as the number of the fastening jaws 39 .

An inlet 47 and an outlet 49 are formed at both ends of the cover body 41 in the longitudinal direction, and the inlet 47 and the outlet 49 have a semicircular shape, respectively. The end hook 16 is positioned at the inlet 47 and the outlet 49 . A cable 10 may be located at the outlet 49 .

Hereinafter, the operation of the unlocking device according to the present invention having the configuration as described above will be described in detail.

In the present invention, the pulling handle 20 is located on the cradle 28 . The handle tube 24 of the pull handle 20 is positioned on the seating through-port 30 so that the pull handle 20 is fixed to the cradle 28 . Both ends of the handle tube 24 are installed by being press-fitted into the seating-through part 30 , respectively. The handle tube 24 is press-fitted through the doorway 32 in order to allow the handle tube 24 to enter the seating through portion 30 . The state in which the pull handle 20 is installed on the cradle 28 is shown in FIG. 1 as described above.

In addition, the end hook 16 fixed to the front end of the covering part 14 of the cable 10 is the first fixing plate 36 in a state in which the fixing cover 40 is separated from the hanging part 34 . and the second fixing plate 36'. The hook groove 18 of the end hook 16 is positioned on the hook 37 , and the step 18 ′ of the end hook 16 is hooked on the stop jaw 38 . In this state, the fixing part cover 40 is fastened to the first and second fixing plates 36 and 36'. When the end hook 16 is fixed to the hook fixing part 34 in this way, the end hook 16 is coupled to the covering part 14, so that the inner wire 12 is connected with the covering part 14. It can move relative to the end hanger (16). Movement of the inner wire 12 may be made by pulling the pulling handle 20 .

Since the pulling handle 20 is fixed to the cradle 28, the inner wire 12 cannot be pulled. In this state, when the latch of the actuator is not electrically operated, the locking state of the actuator must be released using the pull handle 20 .

For this, the operator must separate the pull handle 20 from the cradle 28 . This is because the latch of the actuator can be moved to the unlocked state only when the inner wire 12 moves a certain length or more by pulling the pulling handle 20 .

In order to separate the pull handle 20 from the cradle 20, the operator moves the handle tube 24 part upward in the state of FIG. 1 based on the drawing. When the handle tube 24 is moved upward, the entire pull handle 20 is moved upward, and the portion where the handle tube 24 does not cover the ring wire 22 is in the seating through part 30 . is located That is, a portion of the ring wire 22 is located in the seat through-through portion 30 . This state is shown in FIG. 6 .

In this case, the ring wires 22 at both ends of the handle tube 24 may be simultaneously positioned in the seating through-portion 30 . However, since it is possible for the handle tube 24 to move relative to the ring wire 22, the handle tube 24 moves to one side along the ring wire 22, and the ring wire 22 on one side. Only the seat through-portion 30 is positioned and the ring wire 22 on the other side may be covered by the handle tube 24 . Even in this case, the ring wire 22 located in the seating through-port 30 may come out of the holder 28 through the doorway 32 . Once, as shown in FIG. 7, when one side of the pulling handle 20 comes out of the cradle 28, it is possible to separate the opposite handle tube 24 from the seating through-portion 30 with relatively little force. .

On the other hand, the ring wire 22 from above may be located at the same time in the seating through-portion (30). In this case, it is enough to move the pull handle 20 toward the surface of the frame 26 so that the ring wire 22 exits from the seating through-section 30 at the same time through the doorway 32 .

After the pulling handle 20 is separated from the cradle 28 in this way, the operator can pull the pulling handle 20 by a certain distance or more in the state shown in FIG. 8 . When the pulling handle 20 is pulled, a force is transmitted to the inner wire 12 through the connection block 19 , and the covering portion 14 of the cable 10 is attached to the end hanger 16 . Since it is fixed to the hanger fixing part 34 by this, the inner wire 12 can move relative to the covering part 14 . Accordingly, as the inner wire 12 is pulled, the latch of the actuator is operated to release the locked state.

In the above, even though all components constituting the embodiment of the present invention have been described as being combined or operated in combination as one, the present invention is not necessarily limited to this embodiment. That is, within the scope of the object of the present invention, all the components may operate by selectively combining one or more.
