Description

Door inside handle assembly with override function {Door inside handle assembly with override function for vehicle}

The present invention relates to a door inside handle assembly for a vehicle, and more particularly, to a door inside handle assembly having a function of opening the door at a time while the knob lock is released when the door inside handle is opened.

In general, the door lock device installed in the vehicle releases the lock state of the door latch according to the operation of the inside handle inside the vehicle interior, or releases the lock state of the door latch according to the operation of the outside handle outside the vehicle interior, and also operates a key. This is to release the lock state of the door latch.

In addition, a safety knob for restricting the release of the door latch in the vehicle compartment is provided separately in relation to the locking and unlocking of the door.

If the vehicle door is normally locked by the inside handle and the safety knob, the door must be unlocked by pulling the safety knob and then unlocked by pulling the inside handle.

Such a door opening method is inconvenient to operate the safety knob lever and the inside handle which are separated from each other, and thus, in recent years, when the inside handle is operated, the override that opens the door in such a way that the safety knob is operated together ( Override) A lot of devices are being applied.

The override device is a function that allows the door to be opened at a time while the safety knob lock is released when the door inside handle is opened. When the driver or the passenger pulls the inside handle, as shown in FIG. 1A, in the direction of the inside lever 100 and the solid arrow Simultaneously with movement, the master lock link 110 is moved while moving the protrusions 120 formed in the master lock link 110, and the latch (not shown) is made to open while being released at the same time.

However, in the case of a conventional override device, since the override function is performed in a narrow space in a complicated structure inside the latch, serious safety problems such as malfunction of the latch and open failure may occur immediately in case of component deformation and damage.

In addition, there is a problem of causing an override operation failure in the evil mode.

For example, when the inner handle is pulled out while the safety knob is grasped so as not to be forcibly released when the door is opened, as shown in FIG. 1A, the inside lever 100 moves in the direction of the solid arrow to the master lock link 110. ) Receives a force in the direction of the dotted arrow and eventually becomes a state as shown in FIG.

In such a malicious mode, additional problems such as cable deformation and departure may occur.

Accordingly, the present invention has been made in view of the above, and implements a new type of override method that can simultaneously release the safety knob lock during the inside handle open operation through an interlocking mechanism using a locking structure between the inside handle and the safety knob. Accordingly, an object of the present invention is to provide a door inside handle assembly for an automobile having an override function capable of securing a functional improvement and quality of an override, such as solving a serious safety problem caused by deformation or breakage of a latch internal component or a cable.

In order to achieve the above object, a door inside handle assembly for an automobile having an override function provided by the present invention includes a safety knob installed in a rotatable structure at an upper side in a handle housing, and an inside handle installed in a rotatable structure at a lower side in a handle housing. In particular, the safety knob and the inside handle are arranged side by side above and below with the bottom and top of each other in close proximity to each other, and the rear side of the inside handle extends to the upper end of the safety knob The engaging projection is formed integrally, it is characterized in that the safety knob can also be rotated at the same time during the open operation of the inside handle.

Door inside handle assembly provided in the present invention has the following advantages.

First, the internal handles and safety knobs themselves solve the evil mode of operation, thereby solving serious safety problems due to deformation and breakage of the latch internal connection structure or components.

Second, since no force is transmitted to the cable during the evil mode of operation, serious safety problems due to cable deformation and breakage can be solved.

Third, when a load exceeding a prescribed amount of the handle is damaged, for example, an inside handle, only the override function is lost, and there is no problem in the function of the latch, thereby ensuring safety related to the door opening.

Figure 3 is a rear perspective view showing the door inside handle assembly according to an embodiment of the present invention
4A and 4B are schematic views showing an operating state of a door inside handle assembly according to an embodiment of the present invention.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

2 and 3 are perspective views showing the door inside handle assembly according to an embodiment of the present invention.

As shown in Figs. 2 and 3, the door inside handle assembly has a feature implemented in the inside handle 12 and the safety knob 11 itself without implementing the override function within the complicated structure inside the latch.

To this end, the door inside handle assembly is provided with a handle housing 10 that serves as a base, the handle housing 10 is a safety knob 11 that can be locked and unlocked switch and the inside handle capable of locking and unlocking the latch 10 are provided above and below, respectively.

The safety knob 11 and the inside handle 12 are respectively disposed side by side in a state in which the bottom and top of the portion fitted to the bottom and top of each other, that is to be fitted to the shaft 15 to be described later adjacent to each other, the handle The upper and lower ends are fitted on the housing 12 by a shaft 15 which is supported to be rotatably supported.

At this time, the spring 16 is interposed between the shaft of the safety knob 11 and the inside handle 12 so that the safety knob 11 or the inside handle 12 are in the original position by the spring force without operating force. Can be returned to.

The cables 17a and 17b extend from the safety knob 11 and the inside handle 12, respectively, and the cables 17a and 17b extending at this time are connected to a latch bundle (not shown) and the like, so that the knob or the handle operating force is reduced. It can be transmitted through the cables 17a and 17b.

Here, the operation of locking and unlocking is performed by the operation of the safety knob and the inside handle, and the operation of locking and releasing the latch is the same as in the related art, and thus a detailed description thereof will be omitted.

In particular, the inside handle 12 and the safety knob 11 will have a relationship that works in conjunction with each other.

To this end, a rear surface of the inside handle 12, that is, the rear surface of the portion to be fitted to the shaft 15 is vertically formed with a vertical locking projection 14 extending a predetermined length to the top, the safety knob 11 The rear end of the engaging end 13 is made of a flat vertical surface is provided.

Here, the locking protrusion 14 in the inside handle 12 is in contact with the locking end 13 provided in the safety knob 11 or in a state of being disposed in close proximity.

Accordingly, when the inside handle 12 is pulled to open the door, the safety knob 11 may also be rotated at the same time by contact interference between the locking protrusion 14 and the locking end 13.

At this time, in the case of the locking protrusion 14 in the inside handle 12, the locking end 13 of the safety knob 11 is positioned in contact with the inside (inside the handle housing) toward the outside (inside), As a result, the lock and unlock can be switched by a single operation of the safety knob 11 alone without the inside handle 12.

That is, since the safety knob 11 can be freely rotated by itself without being affected by the locking protrusion 14, the safety knob 11 is operated by only the safety knob 11 without manipulating the inside handle 12 to lock it as in the conventional inside handle. And unlock switching is possible.

Therefore, looking at the operating state of the door inside handle assembly is configured as follows.

4A and 4B are schematic views showing an operating state of a door inside handle assembly according to an embodiment of the present invention.

As shown in FIGS. 4A and 4B, where FIG. 4A shows the pre-operation state and FIG. 4B shows the post-operation state.

When the driver or the passenger pulls the inside handle 12, the inside handle 12 at this time rotates toward the interior about the shaft 15, and at the same time, the locking protrusion 14 on the inside handle 12 is safety. Since it pushes out the rear locking end 13 of the knob 11, the safety knob 11 is also rotated.

Accordingly, the latch is opened while the latch is unlocked at the same time, and eventually the vehicle door is in an openable state.

That is, an override function forcing the safety knob 11 to be forcibly rotated by the contact action between the locking protrusion 14 and the locking end 13 when the inside handle 12 is operated may be implemented.

Then, after performing the override function, when the operating force is released, the inside handle 12 and the safety knob 11 are returned to their original positions by the spring force.

As described above, the door inside handle assembly according to the present invention implements an override function by using a locking structure between the inside handle and the safety knob, thereby completely preventing serious safety problems due to a malfunction of the latch, a failure of opening, a deformation and a breakage of the cable, and the like. It can be excluded, and thus, there is an advantage in that it is possible to improve the merchandise as well as securing reliability of the override function.
