Abstract
Description
Technical Field
[0001] The present invention relates to the field of vehicle door locking devices for controlling the locking and unlocking of a vehicle door from the inside in order to prevent the door from being opened from the outside. The invention also relates to a vehicle door comprising such a locking device. Background Art
[0002] It is known in the prior art to provide a night-time locking system for vehicle doors that prevents intrusion, theft, or privacy violations by the driver inside the vehicle. A night-time locking system comprises a mechanical lock, typically a hard pin, that can be mounted on the inner panel of the door. When activated, the mechanical lock blocks the door, preferably by inserting a pin around or into the door armrest, to prevent someone from opening the door from the outside.
[0003] However, such night locking systems are typically sold separately, preferably as accessories that can be installed on the door panel by the driver themselves, and may require a specific interface for proper installation.
[0004] Such night locking systems are commonly used in two-person vehicles, advantageously heavy trucks, where the truck drivers take turns resting in the vehicle when the vehicle needs to remain stationary.
[0005] Usually, both drivers have authorization keys that are suitable for opening the doors. Sometimes, it may happen that one driver is resting in the vehicle, and the other driver uses his authorization key and mistakenly invades the privacy of the resting person.
[0006] Since this type of night lock is not connected to the door's latching mechanism, there is still a risk of a breach if it is not installed correctly.
[0007] It is also known to provide a door inner handle frame in a vehicle door, which frame supports an inner door handle that can be rotated to open the door from the inside and a key button that can be manually actuated to prevent the door from being accidentally opened from inside the passenger compartment and intentionally opened by rotating the outer door handle.
[0008] However, in this conventional configuration, the key button only blocks the door's latch system, thus preventing only one of the interior or exterior door handles from opening the door. Someone with an authorized key can unlock the latch system from the outside, allowing the door to be opened using the exterior door handle. Therefore, the risk of intrusion persists.
[0009] Another risk of using such a key button is that the user forgets to unlock the key button when leaving the vehicle, so that the user may be locked out of the vehicle and unable to enter the vehicle because the key button is in the locked position.
[0010] An object of the present invention is to provide a vehicle door locking mechanism that is integrated in the vehicle door locking mechanism to prevent the vehicle from being opened or mechanically unlocked from the outside even if an individual has an authorized key to unlock the door, and the vehicle door locking mechanism prevents the risk of being inadvertently locked outside the vehicle when the user leaves the vehicle cabin without unlocking the key button. Summary of the Invention
[0011] The present invention relates to a vehicle door locking device, comprising:
[0012] -Door latch,
[0013] - a lock cylinder, which is used to lock or unlock the vehicle door by rotating a control paddle linked to the door latch,

[0015] - a stop knob located inside the passenger compartment,
[0016] a stop configured to be displaced between a first position allowing the control paddle to rotate and a second position allowing the control paddle to rotate upon actuation of the stop knob,
[0017] Wherein, the inside handle is configured to shift the stopper to the first position when the inside handle is rotated to open the door.
[0018] Using an inside handle that displaces the stop to the first position when the inside handle is rotated to open the door ensures that the stop is not in the locked position when the user leaves his / her cabin, which therefore avoids a solution where the user is locked out of his / her cabin without having access to the cabin even if he / she has an authorized key.
[0019] According to another aspect of the present invention, the detent knob includes an actuating rod that is displaced between a first position associated with the first position of the detent and a second position associated with the second position of the detent, and wherein the inside handle is configured to displace the actuating rod toward its first position when the inside handle is rotated to open the door.
[0020] According to another aspect of the present invention, rotation of the inside handle is configured to displace the stop to the first position prior to unlatching the latch and opening the door.
[0021] According to another aspect of the present invention, the inside handle is provided on the door inside handle frame, and the stop knob is arranged in the door inside handle frame.
[0022] According to another aspect of the invention, the door latch comprises a control lever for unlocking the latch, the control lever being linked to a control paddle of the lock cylinder, and the stopper contacts the latch in the second position.
[0023] According to another aspect of the present invention, the vehicle door latch and the stop are housed in a common housing.
[0024] According to another aspect of the invention, the control lever is rotated according to a rotation axis, and the stop member is configured to be displaced along a linear path that is substantially perpendicular to the rotation axis of the control lever.
[0025] According to another aspect of the present invention, the stopper includes a blocking end configured to intercept the control rod of the latch in the second position.
[0026] The present invention also relates to a vehicle door, comprising the vehicle door locking device as described above.
[0027] According to another aspect of the invention, the door is a side door. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The following achievements are examples. Although the description relates to one or more embodiments, it does not mean that each reference refers to the same embodiment or that features only apply to a single embodiment. Simple features of different embodiments can also be combined to provide other embodiments.
[0037] The present invention relates to a vehicle door locking device capable of being locked from the inside.
[0038] Will refer to Figures 1a to 4b The vehicle door locking device 100 is described. The vehicle door locking device 100 is provided in a Figure 1a The inside of a door 1 of a vehicle is shown, for example a truck door or a car door. The door may be a side door.
[0039] In particular, the present invention is applicable to two-passenger vehicles in which at least two drivers possess authorized keys. In this specification, it should be understood that the authorized key may be a mechanical and / or electronic key with remote control or hands-free access. The vehicle door locking device 100 is configured to prevent one driver (despite possessing an authorized key) from intruding on the privacy of another driver who is resting in the passenger compartment.
[0040] Figure 1a The vehicle door 1 in FIG. 1 comprises an outer panel 2 and an inner panel 3, between which a door locking device 100 is arranged. In this view, the door locking device 100 is only partially visible.
[0041] Figure 1a The door latch 30 is partially shown and includes a rotary latch fork 32 provided on a lateral side of the vehicle door 1, said latch fork 32 being rotatable in a manner reversibly engaging in a striker (not shown) formed on the door frame of the vehicle door 1 for opening or closing the vehicle door 1. The latch fork 32 can be engaged by the door inner handle 4 (at Figure 1b ) or outside door handle 5 (visible in Figure 1a (not visible) actuation.
[0042] Figure 1b Shown from Figure 1a An isolated, enlarged view of the inner door handle frame 7. The inner door handle frame 7 supports the inner door handle 4. Specifically, a motion lever is provided on the inner door handle frame 7. The motion lever may be the inner door handle 4 provided on the inner door handle frame 7. The motion lever is linked to the door latch 30 to allow the vehicle door 1 to be opened from inside the passenger compartment by rotating the inner door handle 4. The motion lever may be linked to the door latch 30 via a Bowden cable or any other suitable mechanical link.
[0043] When the latch fork 32 is engaged in the striker, the door 1 is held closed, and when either of the door handles 4 , 5 is rotationally actuated, the latch fork 32 is released from the striker to allow opening of the door 1 .
[0044] The door handle frame 7 also supports the stop knob 6 of the displaceable stop member 40 (the stop member is Figure 3 、 Figure 4a and Figure 4b (shown in more detail in [ 15 ]). The stop knob 6 can be manually actuated to prevent the release of the latch fork 32, thereby preventing the vehicle door 1 from being opened from the outside and preventing the vehicle door 1 from being unlocked even when an authorized key is used. This operation will be further described in the following paragraphs. The stop knob 6 may include, for example, a pivoting knob. The stop knob 6 can then be rotated between an unlocked position, in which the door 1 can be unlocked with the authorized key, and a locked position, in which the door 1 cannot be unlocked with the authorized key.
[0045] Figure 2 An exemplary embodiment of a vehicle door locking apparatus 100 is shown that is arranged between an outer panel 2 and an inner panel 3 of a vehicle door 1. The vehicle door locking apparatus 100 includes a key cylinder 10, a control paddle 20, a door latch 30, and an inner door handle frame 7.
[0046] In particular, only a portion of the outer plate 2 supporting the lock cylinder 10 and the outer door handle 5 is shown, while the inner door handle frame 7 supporting the inner door handle 4 and the stop knob 6 is not clearly visible, but the inner door handle frame 7 can be seen in FIG. Figure 1b On visualization.
[0047] The lock cylinder 10 includes an inner surface connected to the control paddle 20, which also includes a Figure 2 The keyhole is accessible from the outer panel 2 (ie from the outside) to allow the introduction of an authorized key that can be rotated to actuate the rotation of the control paddle 20, thereby locking or unlocking the vehicle door 1.
[0048] exist Figure 2 , a door latch 30 is shown having a latch fork 32 mounted in a housing 50 .
[0049] The control paddle 20 is mechanically linked to the door latch 30 in a rotatable manner by means of a rod 21. Thus, a mechanical connection is established between the control paddle 20 and the door latch 30 to allow locking or unlocking of the door latch 30. Locking of the door latch 30 prevents either handle 4, 5 from releasing the latch fork 32 to open the vehicle door 1.
[0050] The exterior door handle 5 and the interior door handle frame 7, more specifically the interior door handle 4, are each linked to a door latch 30 by means of Bowden cables 22, 22'. The Bowden cables 22, 22' allow a mechanical connection to be established between each of the handles 4, 5 and the door latch 30, so that when either handle 4, 5 is rotated, a latch fork 32 is actuated to release the vehicle door 1. The interior door handle 4 and the exterior door handle 5 may be linked to the door latch 30 by other suitable mechanical means.
[0051] Furthermore, the door inner handle frame 7 is connected to the housing 50 of the door latch 30 by means of a stop Bowden cable 8. More specifically, the stop Bowden cable 8 connects the stop knob 6 shown in FIG. 1 to the stop member 40 (at Figure 3 、 Figure 4a and Figure 4b (see in the ).
[0052] The stopper 40 is advantageously arranged to block the rotation of the control paddle 20 so as to prevent the door 1 from being opened from the outside. This operation will be better explained in the following paragraphs.
[0053] Reference Figure 3 The door latch 30 includes a control rod 31 for unlocking the latch 30. The control rod 31 is Figure 2 The rod 21 shown is linked to a control paddle 20 of the lock cylinder 10 .
[0054] The control rod 31 is mounted on the housing 50 of the door latch 30 and is used to control the unlocking of the latch 30. By unlocking the door latch 30, Figure 1a and Figure 2 The latch fork 32 shown in FIG can be released from the striker to allow the vehicle door 1 to be opened by rotating either the inner door handle 4 or the outer door handle 5 .
[0055] More specifically, the control lever 31 has a base body 311 that is pivotally mounted on the housing 50 of the door latch 30. The base body 311 includes a distal end provided with a port 312. Figure 2 One end of the rod 21 shown in FIG can be engaged in the port 312 to cause the rotation of the control rod 31. The control rod 31 can be rotated according to the rotation axis 31A to allow the door latch 30 to be unlocked. This rotation can generate a torque for unlocking the door latch 30.
[0056] Therefore, when the control paddle 20 rotates, the control lever 31 may also rotate according to its rotation axis 31A to unlock the door latch 30 .
[0057] Figure 3 Also shown is the aforementioned stopper 40, which is placed between the outer panel 2 and the inner panel 3 of the vehicle door 1. The stopper 40 is mounted in such a manner as to be movable between a first position and a second position. In particular, the first position in which the stopper is pulled in the direction D1 allows the control paddle 20 to rotate, and in the second position in which the stopper is pulled in the direction D1 Figure 3 The second position shown in FIG and corresponding to the push position in the direction D2 blocks the rotation of the control paddle 20 to prevent the vehicle door 1 from being opened from the outside. This operation will be further explained in the following paragraphs.
[0058] The stop knob 6 shown in FIG. 1 is Figure 2The stop Bowden cable 8 shown in FIG is connected to the stop member 40. When the stop knob 6 is actuated, traction or push is applied on the stop member 40 by the Bowden cable 8, and the stop member 40 becomes elastically biased between the first position and the second position or opposite to allow the stop member 40 to shift.
[0059] like Figure 3 As shown, the stopper 40 is configured to be displaced along a linear path 40A that is substantially perpendicular to the rotation axis 31A of the control lever 31. The stopper 40 is displaceable along a guide rail 52 provided on the housing 50 between a first position and a second position.
[0060] By housing the stop 40 in the same housing 50 as the door latch 30 and due to the linear vertical path of the stop 40, the stop 40 is able to interact directly with the lever 31 in order to intercept its rotational path. Thus, when the driver wants to maintain his privacy, there is no need to use any additional security locks, such as an additional night lock.
[0061] The stop 40 preferably has a parallelepiped flat block 42 that can be displaced along a rib-shaped guide 52. The flat block 42 has a blocking end 44 configured to intercept the control rod 31 of the door latch 30 in the second position. Figure 3 The stop 40 is shown in a second position in which it is placed in contact with the control rod 31 .
[0062] The control rod 31 includes a distal end provided with a blocking extension 313 that extends toward the stopper 40. The blocking end 44 of the stopper 40 is configured to intercept the blocking extension 313 formed on the control rod 31.
[0063] Due to the interaction with the distal blocking extension 313 of the control rod 31 , the blocking end 44 of the stop 40 is able to counteract the rotational force of the control rod 31 by performing minimal work.
[0064] By contacting the control rod 31 , the stopper 40 can provide resistance to counteract the rotational force of the control rod 31 so as to block the rotation of the control rod 31 , thereby preventing the control rod 31 from unlocking the door latch 30 , thereby preventing the vehicle door 1 from opening when the outside handle 5 is actuated.
[0065] By blocking the rotation of the control rod 31, Figure 2 The stopper 40 can also indirectly block the rotation of the control paddle 20 by establishing a mechanical connection with the rod 21 shown. Therefore, even if an authorized key is introduced into the keyhole 11, the control paddle 20 cannot be rotated to unlock the vehicle door 1, and therefore the control rod 31 cannot be rotated to unlock the latch 30.
[0066] In particular, the latch 30 may include an electrical actuator that can be controlled by a remote control key (not shown) and activated by the driver via the remote control. In the event that the remote control is used to unlock the vehicle door 1, the fact that the control rod 31 is blocked also prevents the remote control key from unlocking the latch 30.
[0067] Therefore, in the second position of the blocker 40, the vehicle door 1 can neither be unlocked nor opened. In other words, the stopper 40 ensures the locking of the vehicle door 1 and at the same time ensures that the latch 30 cannot move to open the door 1.
[0068] Depending on the door 1 (right or left door) on which the control paddle 20 is mounted, the control paddle 20 can be configured to rotate in a clockwise direction to lock the door 1, or configured to rotate in a counterclockwise direction. The stopper 40 is ideally placed to intercept the rotational path of the control rod 31. Figure 4a A blocker 40 is shown, the blocking end 44 of which is arranged to block the control rod 31 having a clockwise rotation path, and Figure 4b The blocking end 44 is shown arranged to block the control rod 31 having a counter-clockwise rotational path.
[0069] The first position allowing the control rod 31 to rotate may correspond to a static state of the stopper 40. The second position blocking the rotation of the control rod 31 may correspond to an active state of the stopper 40, in which the stopper 40 may interact with the control rod 31.
[0070] The door inner handle 4 is further configured to displace the stopper 40 to the first position when the door inner handle 4 is rotated to open the door 1 . Figures 5a to 5c In the embodiment shown, the stop knob 6 comprises an actuating rod 6a. Figure 5a The first position shown is associated with the first position of the stop member 40 and Figure 5b The first position corresponds to the unlocked position of the stop knob 6, and the second position corresponds to the locked position of the stop knob 6. The stop knob 6 can be rotatably arranged about a first axis Y1, with the operating portion 6b extending on one side and the actuating rod 6a extending on the other side. The operating portion 6b and the actuating rod 6a can extend at an angle of between 70° and 100°, for example, 90°, relative to each other.
[0071] The inner handle 4 further comprises a rod 4a configured to push the actuating rod 6a and rotate the stop knob 6 towards its first position when the inner handle 4 is rotated. Figure 5cAs shown, the inside handle 4 can be rotatably arranged about a second axis Y2 parallel to the first axis Y1, with the operating portion 4b extending on one side and the rod 4a extending on the other side. The operating portion 4b and the rod 4a can extend at an angle of between 70° and 100° relative to each other, for example, 90°. Other mechanical arrangements can also be implemented to ensure that the stopper 40 is unlocked when the inside handle 4 is rotated.
[0072] Furthermore, the inside handle 4 is configured to displace the actuating rod 6a towards its first position before unlocking the door latch 30 and opening the door 1 via the Bowden cable 22 ′ when the inside handle 4 is rotated to open the door 1 .
[0073] Figure 6 The diagram shows the evolution of the states of the stopper 40 (curve A), the locking mechanism of the door latch 30 (curve B), the door 1 (curve C), and the inside handle 4 (curve D) as the inside handle 4 rotates from a first state S1, corresponding to its rest position, to a second state S2, associated with the fully rotated position. At a first rotation angle of the inside handle 4, designated P1, the stopper 40 shifts from its second position, designated S2'", to its first position S1'". This shifting of the stopper 40 is achieved by the rotation of the actuating rod 6a of the stop knob 6, as described above. At a second rotation angle of the inside handle 4, designated P2, the locking mechanism of the door latch 30 is unlocked. Thus, the locking mechanism switches from the first state S1', associated with the locked position, to the second state S2', associated with the unlocked position. This unlocking can be achieved mechanically via an electrical signal or via a known mechanism. At a third rotation angle of the inside handle 4, designated P3, the door 1 is opened. This opening is achieved by rotating the control paddle 20 via the Bowden cable 22 ′ to release the latch fork 32 from the striker and allow the door 1 to be opened.
[0074] Other mechanisms may be used to achieve displacement of the stop 40 towards its first position when the inside handle 4 is rotated.
[0075] The different Bowden cables 8 , 22 , 22 ′ and in particular the stop Bowden cable 8 can be accommodated in a protective housing in order to prevent them from being accessed by introducing objects through the window seal.
[0076] This arrangement allows the inner door handle 4 to move the stopper 40 to its first position to allow unlocking and opening of the vehicle door 1 .
[0077] Therefore, if the driver in the passenger compartment wishes to unlock and open the vehicle door 1, there is no need for additional actuation of the check knob 6. However, if the driver only wishes to unlock the vehicle door 1 without opening the vehicle door 1, the check knob 6 can be actuated to shift the check member 40 to its first position without opening the vehicle door 1.
[0078] The present invention also relates to a vehicle door 1 comprising the vehicle door locking device 100 as described above.
[0079] Thus, the present invention enables the user to prevent the door from being opened from outside the vehicle (even with an authorized key). Furthermore, the present invention enables the door 1 to be opened from the inside by a simple rotation of the inside handle 4, since such rotation will sequentially trigger the release of the stopper 40, the unlocking of the door latch 30, and the opening of the door 1, which prevents the risk of being locked out from the outside when the driver leaves his cab and inadvertently forgets to unlock the locking knob.
