6 to 9 for a locking or unlocking process of the locking unit and the striker 160 constituting the locking device 100 prior to describing a specific operating relationship of the vehicle locking device 100 according to an embodiment of the present invention. Referring to, the explanation is as follows.

6 to 9 are plan views sequentially illustrating a relationship in which a locking device for a vehicle according to an embodiment of the present invention changes from a locked state to an unlocked state and then to a locked state again.

6 illustrates a state in which the locking unit is coupled to the striker and the tailgate or trunk lid is coupled to the vehicle body.

Referring to FIG. 6 , as one end of the detent 122 interlocked with the release lever 120 is engaged in the hooking portion 132 of the fork portion 130, the fork portion 130 is a second hinge Rotation from (138) is limited. At this time, the striker 160 is disposed in the receiving groove 134 of the fork part 130, and the striker 160 is trapped in the receiving groove 134 by the foul 136 of the fork part 130. , the tail gate or the trunk lid is coupled to the vehicle body by the combination of the locking unit and the striker 160 .

At this time, the release lever 120 and the detent 122 are given a force to rotate clockwise around the first hinge 124 by the torsion spring 126, and the fork part 130 also torsion spring ( 140), a force to be rotated clockwise about the second hinge 138 is given.

The release lever 120, the detent 122, and the fork part 130 are given a rotational force in one direction by the torsion springs 126 and 140, respectively, but a force greater than the tension of the torsion springs 126 and 140 When applied, rotation can be made in the opposite direction as well. However, as described above, since the hooking part 132 of the fork part 130 is caught by the detent 122, rotation is limited even when an external force is applied.

As the rotation of the fork part 130 by the detent 122 is restricted, the contact end 128 comes into contact with the contact sensor 150 when the tailgate or trunk lid is coupled to the vehicle body and locked. do.

In this way, when an electrical or mechanical signal is applied to the locking unit to open the tailgate or trunk lid to the vehicle body in a state where the tailgate or trunk lid is coupled to and locked from the vehicle body, FIGS. 7 and 8 show As described above, as the release lever 120 rotates by a certain angle, the fork 130 is disengaged from the striker 160, so that the tailgate or trunk lid can be opened with respect to the vehicle body.

FIG. 7 illustrates an intermediate stage in which the locking unit is disengaged from the striker, and FIG. 8 illustrates a state in which the locking unit is completely disengaged from the striker and the tailgate or trunk lid is opened with respect to the vehicle body.

When the release lever 120 is rotated counterclockwise by an electrical or mechanical signal as shown in FIGS. 7 and 8 , the detent 122 also rotates in conjunction with the release lever 120, so that the fork part The locking portion 132 of 130 and the locking are released.

Accordingly, the fork unit 130 can be rotated in a counterclockwise direction when a predetermined external force is applied.

For reference, in describing the vehicle locking device 100 according to an embodiment of the present invention, the rotation directions of the release lever 120, the detent 122, and the fork 130 are described as clockwise or counterclockwise. It is only expressed for the convenience of description in the direction of viewing the drawings, which may vary depending on the viewing direction, so it is not intended to limit the direction.

When the release lever 120 and the detent 122 are rotated counterclockwise by an electrical or mechanical signal, the contact end 128 formed on one side of the release lever 120 is shorted with the contact sensor 150, The contact sensor 150 applies this signal to an elevating device (not shown) to cause the elevating device to partially lift the tailgate or trunk lid from the vehicle body.

As the tailgate or trunk lid is lifted relative to the vehicle body by the lifting device, the striker 160 fixed to the vehicle body pushes the pawl 136 of the fork unit 130 whose rotation is released, and lifts the fork unit 130. As shown in FIGS. 7 and 8 by rotating in a counterclockwise direction, it can come out of the receiving groove 134 of the fork part 130 .

As shown in FIG. 8 , when the striker 160 comes out of the receiving groove 134 of the fork part 130, the locking unit and the striker 160 are disengaged, so that the tailgate or trunk lid of the vehicle body is unlocked, and in this state, other people including the driver can completely open the tailgate or trunk lid by rotating it from the vehicle body.

As shown in FIG. 8, when the striker 160 comes out of the receiving groove 134 of the fork part 130, the fork part 130 rotates clockwise again by the elastic restoring force of the torsion spring 140, As the release lever 120 and the detent 122 are also rotated clockwise again by the elastic restoring force of the torsion spring 126, as shown in FIG. 9, the detent 122 catches the fork 130 The part 132 is hooked again.

The operational relationship of the above-described vehicle locking device 100 can be made smoothly when a special load is not applied to the upper side of the tailgate or trunk lid.

However, the operation may not be performed smoothly in a state where a lot of snow is accumulated on the upper side of the tailgate or trunk lid or a load exceeding a certain load is placed.

For example, as the release lever 120 and the detent 122 rotate counterclockwise by an electrical or mechanical signal, the contact end 128 is short-circuited with the contact sensor 150, so that the lifting device is operated in the tailgate or trunk. When a certain portion of the lid is lifted from the vehicle body, in a state where a certain load of snow is accumulated or a load is placed on the tailgate or trunk lid, the lifting device may not be able to lift the tailgate or trunk lid due to the load. .

Therefore, the striker 160 may not come out of the receiving groove 134 while pushing the foul 136 of the fork part 130, and in this state, the release lever 120 and the detent 122 and the fork part When 130 is returned to its original state by the elastic restoring force of torsion springs 126 and 140, the striker 160 remains trapped in the receiving groove 134 of the fork 130 as shown in FIG. As a result, unlocking of the tailgate or the trunk lid from the vehicle body is not performed.

When such a case occurs, as pointed out in the prior art, the driver or another person directly holds the tailgate or trunk with his hand and lifts it upward and opens it using the remote controller or car key at the same time. discomfort may result.

In the present invention, even when a certain load of snow or luggage is placed on the upper side of the tailgate or trunk lid, in a state where the driver or other person unlocks the locking device 100 using a remote controller or a car key, the tail By maintaining the open state until the gate or the trunk lid is lifted upward, the above problem can be eliminated. The operation relationship thereof will be described with reference to FIGS.

10 is a plan view showing a vehicle locking device according to an embodiment of the present invention in a locked state, FIG. 11 is a plan view in a state in which the cover housing is excluded in FIG. 10, and FIG. 12 is a cross-sectional view taken along line A-A of FIG. 10 .

13 is a plan view illustrating a case in which the vehicle lock device according to an embodiment of the present invention is unlocked, but the tailgate or the trunk lid is not opened by a load, and FIG. 14 is a plan view in which the cover housing is excluded from FIG. 13 It is a plan view of the state, and FIG. 15 is a BB line cross-sectional view of FIG. 13.

16 is a plan view illustrating a case in which the vehicle locking device according to an embodiment of the present invention is unlocked and the tailgate or trunk lid is fully opened by rotating with respect to the vehicle body, and FIG. 17 is a plan view showing the cover housing in FIG. 16 It is a plan view of an excluded state, and FIG. 18 is a cross-sectional view taken along line C-C of FIG. 16 .

First, referring to FIGS. 10 and 11 , in a state where the striker 160 is disposed in the receiving groove 134 of the fork part 130, the hooking part 132 of the fork part 130 is detent 122 As rotation is restricted by being caught by the striker 160, the striker 160 is trapped in the receiving groove 134 of the fork part 130.

Accordingly, since the locking unit and the striker 160 are coupled, the tailgate or trunk lid is coupled to the vehicle body and maintained in a locked state.

At this time, the snow lever 300, which may be integrally formed in the cover housing 200 of the locking unit, has a holding portion 320 formed on one surface of the release lever 120 as shown in FIG. It is disposed outside the slot 120a and not in contact with the release lever 120.

In this state, when an electrical or mechanical signal is applied to the locking unit to open the tailgate or trunk lid with respect to the vehicle body, as shown in FIGS. 13 and 14, the release lever 120 rotates by a certain angle. The rotation restriction of the fork unit 130 may be released.

That is, as the release lever 120 rotates, the detent 122 interlocks and rotates, so that the end of the detent 122 is spaced apart from the hooking part 132 of the fork part 130, so that the fork part 130 ) becomes possible to rotate.

At this time, if snow is accumulated over a certain load or a load is placed on the top of the tail gate or trunk lid, the lift device lifts the tail gate or trunk lid by a signal according to the short circuit between the contact end 128 and the contact sensor 150. Since it cannot be raised, the striker 160 cannot rotate while pushing the foul 136 of the fork part 130, so that it cannot come out of the receiving groove 134, and thus the striker 160, as shown in FIG. It is located in the receiving groove 134 of the fork part 130 as it is.

However, in a state in which the release lever 120 rotates counterclockwise by an electrical or mechanical signal so that the detent 122 releases the rotation restriction of the fork 130, the release lever 120 operates on the snow lever 300. ) As it is supported in a rotated state by the torsion spring 126, it does not rotate back to its original state by the elastic restoring force of the torsion spring 126, and the state in which the rotation restriction of the fork part 130 is released is maintained as it is.

That is, when the release lever 120 is rotated counterclockwise by an electrical or mechanical signal, the holding portion 320 of the snow lever 300 rides over the locking jaw 120c of the release lever 120 and the locking jaw. (120c) is located in the slot 120a on the inside, and when the holding part 320 of the snow lever 300 completely rides over the hooking jaw 120c and is located in the slot 120a, in FIGS. 13 and 15 As shown, the end of the holding part 320 is supported in the support groove 120b between the locking jaw 120c and the slot 120a, so that the release lever 120 is a torsion spring 126 as shown in FIG. ) It is possible to maintain the state in which the rotation restriction of the fork part 130 is released without returning to the original state by the elastic restoring force.

In this state, if the driver or another person lifts the tailgate or trunk lid with a force greater than the load applied to the upper side of the tailgate or trunk lid, as shown in FIGS. 16 and 17, the striker 160 As the fork part 130 is rotated while pushing the fowl 136, it can come out of the receiving groove 134 of the fork part 130.

In this way, as the striker 160 rotates the fork part 130 while pushing the foul 136, the protrusion 170 formed on one surface of the fork part 130 also rotates in conjunction, and the protrusion 170 When in contact with the protrusion 330 formed on one surface of the stick portion 310 of the lever 300, the snow lever 300 is slightly lifted up as shown in FIG. 18 by its own elasticity.

As described above, the snow lever 300 has a predetermined elasticity as one end of the snow lever 300 is integrally connected to one side of the cover housing 200, so that the protrusion 170 is formed according to the rotation of the fork 130. When it comes into contact with 330, it is lifted up by its own elasticity.

As such, when the protruding part 170 comes into contact with the protruding part 330 of the snow lever 300 as the fork part 130 rotates, the inclined surface part 172 of the protruding part 170 and the protruding part 330 first As they come into contact, the snow lever 300 can be lifted slowly.

And, when the protrusion 330 of the snow lever 300 comes into contact with the flat surface of the protrusion 170, the end of the holding portion 320 of the snow lever 300 is the release lever 120 as shown in FIG. It can be lifted to a position higher than the top of the locking jaw 120c formed on, and accordingly, the snow lever 300 releases the rotation restriction of the release lever 120, thereby releasing the release lever 120 and the detent 122 ) may reverse rotate to its original state by the elastic restoring force of the torsion spring 126.

In addition, as the fork part 130 is also reversely rotated to its original state by the elastic restoring force of the torsion spring 140, the detent 122 is caught again by the hooking part 132 of the fork part 130. By this, as shown in FIGS. 10 and 11, the rotation of the fork part 130 is limited, and at this time, the holding part 320 of the snow lever 300 is of the release lever 120, as shown in FIG. It may be disposed outside the slot 120a formed on one surface and not in contact with the release lever 120 .

As described above, in the vehicle locking device 100 according to an embodiment of the present invention, when a certain load of snow is accumulated or a load is placed on the top of the tailgate or trunk lid, the tailgate or trunk lid is locked by the load. Even if a certain part is not lifted in the open state, it is possible to maintain the unlocked state without being locked again, so that the tailgate or trunk lid can be opened more easily.

Those skilled in the art to which the present invention pertains will understand that the present invention can be embodied in other specific forms without changing its technical spirit or essential features. Therefore, the embodiments described above should be understood as illustrative in all respects and not limiting. The scope of the present invention is indicated by the following claims rather than the detailed description above, and all changes or modifications derived from the meaning and scope of the claims and equivalent concepts should be interpreted as being included in the scope of the present invention. do.
