The present disclosure relates generally to a lock assembly and more particularly to a lock assembly for a vehicle having a tailgate or other removable closure.
This section provides background information related to the present disclosure and is not necessarily prior art.
Many motor vehicles come equipped with tailgate assemblies. For example, pickup trucks often include a tailgate assembly that controls access to a bed portion of the pickup truck. In some implementations, tailgate assemblies are removably supported by the bed portion of the pickup truck. In this regard, the full functionality of the truck bed can be utilized by opening the tailgate assembly and/or removing the tailgate assembly from the pickup truck. The removability of tailgate assemblies can also make them vulnerable to car thieves. For this reason, locking systems have been developed to prevent inadvertent and other unwanted removal of the tailgate assembly from the vehicle. In this regard, some vehicles may utilize a handle locking system that prevents the tailgate assembly from opening, and thus prevents the tailgate assembly from being removed from the vehicle. Other vehicles may utilize a trunnion locking system that prevents the tailgate assembly from being removed, regardless of whether the tailgate is open or closed. Current handle locking systems are susceptible to being easily overridden and thus allowing unauthorized individuals to remove the tailgate assembly from the vehicle. Current trunnion locking systems provide an added degree of security as compared to handle locking systems; however, current trunnion locking systems do not allow authorized users to easily remove the tailgate assembly.
This section provides a general summary of the disclosure, and is not a comprehensive disclosure of its full scope or all of its features.
One aspect of the present disclosure provides a lock assembly for locking a tailgate relative to a body assembly of a vehicle. The lock assembly may include a coupling member, a carriage, a trunnion, and a catch. The carriage may be rotatably disposed within the coupling member and may include a first aperture and a first slot. The trunnion may be removably received by the carriage and may include a second aperture aligned with the first aperture. The catch may be movable between a locked position and an unlocked position. The catch may be received by the first aperture and the second aperture in the locked position.
Implementations of the disclosure may include one or more of the following features. In some implementations, the carriage is rotatable relative to the coupling member about a rotational axis and the catch is translatable relative to the coupling member along a translational axis. The rotational axis may be parallel to the translational axis.
In some implementations, the lock assembly includes a biasing member biasingly engaging the catch and configured to translate the catch along the translational axis.
In some implementations, the trunnion is operable to translate through the first slot in a direction perpendicular to the rotational axis when the catch is in the unlocked position.
In some implementations, the coupling member includes a second slot and a third aperture. The third aperture may be aligned with the first and second apertures and the catch may be received by the third aperture in the locked position. The trunnion may be coupled to the tailgate and the carriage may be coupled to the body assembly.
In some implementations, the catch includes a ramped surface configured to slidably engage an outer surface of the trunnion in the locked position.
In some implementations, the lock assembly includes a driver operable to translate the catch from the unlocked position to the locked position. The driver may include at least one of a motor and a solenoid. The lock assembly may include a control module operable to actuate the driver between a locking state and an unlocking state. The control module may include one of a key fob, a switch, and a key.
In some implementations, the catch is configured to rotate within the first aperture about a rotational axis.
Another aspect of the present disclosure provides a lock assembly for locking a tailgate relative to a body assembly of a vehicle. The lock assembly may include a carriage, a trunnion, and a catch. The carriage may include a trunnion-receiving feature and an aperture in communication with the trunnion-receiving feature. The trunnion may be received by the trunnion-receiving feature for translation along a first axis. The trunnion may include a second aperture aligned with the first aperture. The catch may be received by the first aperture and the second aperture for translation along a second axis transverse to the first axis. The catch may be movable between a locked position and an unlocked position along the second axis.
In some implementations, the catch is received by the first aperture and the second aperture in the locked position.
In some implementations, the lock assembly includes a coupling member. The carriage may be disposed within the coupling member for rotation about a third axis parallel to the second axis.
In some implementations, the coupling member includes a slot and a third aperture. The third aperture may be aligned with the first and second apertures. The catch may be received by the third aperture in the locked position.
In some implementations, the second axis is perpendicular to the first axis.
In some implementations, the lock assembly includes a biasing member biasingly engaging the catch and operable to translate the catch along the second axis.
In some implementations, the trunnion is operable to translate in a first direction within the trunnion-receiving feature when the catch is in the locked position and in a first direction and a second direction when the catch is in the unlocked position. The second direction may be opposite the first direction.
In some implementations, the trunnion is coupled to the tailgate and the carriage is coupled to the body assembly.
In some implementations, the catch includes a ramped surface configured to slidably engage an outer surface of the trunnion in the locked position.
In some implementations, a driver is operable to translate the catch from the unlocked position to the locked position.
Yet another aspect of the present disclosure provides a system for locking and unlocking a tailgate relative to a body of a vehicle. The tailgate may be movable between an open position and a closed position relative to the body. The system may include a latch system, a locking system, and a controller. The latch system may be operable between a locked state and an unlocked state. The latch system may permit the tailgate to rotate relative to the body in the unlocked state and prevent the tailgate from rotating relative to the body in the locked state. The locking system may be operable between a locked state and an unlocked state. The locking system may permit removal of the tailgate relative to the body when the latch system and the locking system are in the unlocked state. The locking system may prevent removal of the tailgate relative to the body when the latch system or the locking system are in the locked state. The controller may be in communication with at least one of the latch system and the locking system. The controller may be operable to control the at least one of the latch system and the locking system between the locked state and the unlocked state. The locking system may permit coupling the tailgate to the body when the locking system is in the locked state.
Another aspect of the present disclosure provides a security system for locking and unlocking a tailgate relative to a body assembly of a vehicle. Securing the tailgate may be transparently accomplished with the same securing operation that secures or locks one or more access locations (e.g., doors) of the vehicle. The security system may be motive driven by a power source to engage and disengage the tailgate with the body assembly while in any and all modes of tailgate orientation (e.g., open or closed) relative to the body assembly. The security system may allow removal of the tailgate from the body assembly only when the security system is in an UNLOCK state. The security system may allow securing of the tailgate to the vehicle independent of the LOCK/UNLOCK state of the security system and without performing addition operations beyond aligning a trunnion with a trunnion-receiving feature of a carriage.
Further areas of applicability will become apparent from the description provided herein. The description and specific examples in this summary are intended for purposes of illustration only and are not intended to limit the scope of the present disclosure.
The drawings described herein are for illustrative purposes only of selected configurations and not all possible implementations, and are not intended to limit the scope of the present disclosure.
Corresponding reference numerals indicate corresponding parts throughout the drawings.
Example configurations will now be described more fully with reference to the accompanying drawings. Example configurations are provided so that this disclosure will be thorough, and will fully convey the scope of the disclosure to those of ordinary skill in the art. Specific details are set forth such as examples of specific components, devices, and methods, to provide a thorough understanding of configurations of the present disclosure. It will be apparent to those of ordinary skill in the art that specific details need not be employed, that example configurations may be embodied in many different forms, and that the specific details and the example configurations should not be construed to limit the scope of the disclosure.
The terminology used herein is for the purpose of describing particular exemplary configurations only and is not intended to be limiting. As used herein, the singular articles “a,” “an,” and “the” may be intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms “comprises,” “comprising,” “including,” and “having,” are inclusive and therefore specify the presence of features, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and/or groups thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring their performance in the particular order discussed or illustrated, unless specifically identified as an order of performance. Additional or alternative steps may be employed.
When an element or layer is referred to as being “on,” “engaged to,” “connected to,” “attached to,” or “coupled to” another element or layer, it may be directly on, engaged, connected, attached, or coupled to the other element or layer, or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly engaged to,” “directly connected to,” “directly attached to,” or “directly coupled to” another element or layer, there may be no intervening elements or layers present. Other words used to describe the relationship between elements should be interpreted in a like fashion (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.
The terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections. These elements, components, regions, layers and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, component, region, layer or section from another region, layer or section. Terms such as “first,” “second,” and other numerical terms do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the example configurations.

The coupling assembly 62 may include a bracket 68, a base plate 70, a support housing 72, a support plate 74, a coupling member 76, and a carriage 78. The bracket 68 may include one or more mounting features 80 (e.g., apertures) sized and shaped to receive a fastener (not shown), such as a bolt, screw, or rivet, for example, to couple the bracket 68 to the body 60. In this regard, it will be appreciated that the bracket 68 may be coupled to and/or supported by the body 60 using other techniques, such welding, press-fit, or clips, for example, within the scope of the present disclosure.
The base plate 70 may be coupled to and/or supported by the body 60 and may include one or more mounting features 82 (e.g., apertures) and a support housing-receiving feature 84 (e.g., aperture). The mounting feature 82 may be sized and shaped to receive a fastener (not shown), such as a bolt, screw, or rivet, for example, to couple the base plate 70 to the body 60 and the bracket 68.
The support housing 72 may include a generally hollow cylinder 88, a mounting flange 90, and one or more mounting features 92 (e.g., clips). The cylinder 88 may include a generally cylindrical inner surface 94, a generally cylindrical outer surface 96, and one or more engagement features 98. The engagement feature(s) 98 (e.g., longitudinally extending ribs) may extend radially outward from the outer surface 96. The mounting flange 90 may extend radially outward from the outer surface 96. The one or more mounting features 92 (e.g., clips) may extend axially from the mounting flange 90, away from the cylinder 88. As illustrated in at least
The support plate 74 may include a one or more mounting features 104 (e.g., apertures) and a support housing-receiving feature 106 (e.g., an aperture). In the assembled configuration, the mounting feature(s) 104 may be aligned with the mounting feature(s) 82 of the base plate 70 and/or the mounting features 80 of the bracket 68, such that each fastener (not shown) extends through a mounting feature 104 of the support plate 74 and a mounting feature 80, 82 of the bracket 68 and base plate 70, respectively, in order to secure the support plate 74 to the base plate 70 and to secure the base plate 70 to the body 60. The housing-receiving feature 106 may receive the support housing 72 in order to secure the support housing 72 to the support plate 74. In this regard, the support housing 72 may be disposed within the housing-receiving feature 106 such that the engagement feature(s) 98 engage the support plate 74 in a press-fit configuration.
As illustrated in
The support portion 110 may extend from the base portion 108 of the coupling member 76 and may define a generally hollow cylindrical construct. In this regard, the support portion 110 may include a cylindrical inner surface 116 and a slot 118. The inner surface 116 may surround the support-housing receiving feature 112. The slot 118 may extend through the support portion 110. As will be explained in more detail below, in the assembled configuration, the slot 118 may allow a user to assemble the tailgate assembly 12 to, and/or remove the tailgate assembly 12 from, the body assembly 14.
With reference to
The trunnion-receiving feature 126 may be formed in one or more of the proximal end 122 and the peripheral surface 125. In this regard, the trunnion-receiving feature 126 may include an opening 128 formed in the distal end 124 of the carriage 78 and an opening 130 formed in the peripheral surface 125 of the carriage 78. In some configurations, the opening 128 and/or the opening 130 may be generally U-shaped such that the opening 128 communicates with and/or opens into the opening 130. The distal end 124 of the carriage 78 may include an aperture 132. The aperture 132 may open into and/or communicate with the trunnion-receiving feature 126, including the opening 128 formed in the proximal end 122 of the carriage 78. A size and shape of the trunnion-receiving feature 126 may correspond to a size and shape of the trunnion 34 such that the trunnion 34 can be received by the openings 128, 130 in order to assemble the trunnion 34 within, and remove the trunnion 34 from, the trunnion-receiving feature 126.

The driver 142 may be any variety device and/or assembly configured to move the pin 144 along the axis A2 (e.g., parallel to the axis A2). For example, the driver 142 may include a motor, a solenoid, a pneumatic actuator, or other device that can apply a force on the pin 144 in a direction substantially parallel to the axis A2. In the assembled configuration, the driver 142 may be disposed within the housing 136.
As illustrated in
With reference to
In the assembled configuration, the holder 146 may be translatably disposed within one or more of the support housing 72 and the carriage 78 for translation along the axis A2. In this regard, the pin 144 may be coupled to the holder 146 such that translation of the pin 144 causes the holder to translate along the axis A2. For example, the head 166 of the pin 144 may be rotatably disposed within the proximal cavity 174 such that (i) translation of the pin 144 causes the head 166 and/or the flange 162 to engage the holder 146 in order to translate the holder 146 along the axis A2, and (ii) rotation of the holder 146 about the axis A2 causes the head 166 to rotate within the cavity 174 and causes the catch 150 to rotate about the axis A2.

In order to unlock the tailgate assembly 12 relative to the body assembly 14 (e.g., in order to remove the tailgate assembly 12 from the body assembly 14), the user may actuate the driver 142. In this regard, the user may actuate the driver 142 using a mechanical (e.g., a key) or electronic (e.g., a key fob) communication device. For example, the user may utilize the control module 26 to transmit the UNLOCK signal 27b to the lock assembly 24 and to actuate the driver 142 in order to allow a user to remove the tailgate assembly 12 from the vehicle 10. In this regard, actuating the driver 142 may cause the pin 144 to move along the axis A2 (e.g., away from the trunnion 34). As the pin 144 moves along the axis A2, the catch 150 may exit the aperture 54 of the trunnion 34 and move to an unlocked position (
Once the catch 150 has exited the aperture 54 of the trunnion 34, the user may move the trunnion 34 and/or the tailgate assembly 12 in a direction generally perpendicular to the axis A2. For example, the user may lift the tailgate assembly 12 relative to the body assembly 14, such that the trunnion 34 (i) exits the trunnion-receiving feature 126 of the carriage 78 through the opening 130 and (ii) exits the coupling member 76 through the slot 118.
In a second state, the tailgate assembly 12 may have been removed from the body assembly 14, and the catch 150 may be positioned in the locked position (
If the catch 150 is in the locked position (
As the catch 150 moves towards the wall 178 of the holder 146, the biasing member 148 is compressed by and between the wall 178 and the catch 150 until the catch 150 exits the trunnion-receiving feature 126 of the carriage 78. Once the catch 150 has exited the trunnion-receiving feature 126 of the carriage 78, the trunnion 34 enters the trunnion-receiving feature 126 of the carriage 78 until the aperture 54 of the trunnion 34 is aligned with the aperture 132 of the carriage 78. In particular, the trunnion 34 enters the trunnion-receiving feature 126 until the axis A2 intersects the aperture 54 of the trunnion 34 and the aperture 132 of the carriage 78. Once the aperture 54 of the trunnion 34 is aligned with the aperture 132 of the carriage 78, the biasing member 148 urges the catch 150 to translate in a direction substantially parallel to the axis A2, and away from the wall 178 of the holder 146, until the catch 150 enters the aperture 54 of the trunnion 34.
