Best Mode for Carrying Out the Invention

[0011] The present invention is illustrated and described herein with reference to specific embodiments, but the present invention is not intended to be limited to the illustrated details. Rather, various modifications can be made within the scope and range of equivalents of the claims and within the details, without departing from the invention.

[0012] Throughout the disclosure, various terms are used to describe the physical shape or arrangement of features. The number of these terms is used to describe features that conform to a cylindrical or substantially cylindrical shape characterized by a radius and a central axis perpendicular to the radius. Unless otherwise specified, the terms are given the following meanings. The terms "longitudinal", "longitudinal", "axial", and "axial" refer to a direction, dimension, or orientation parallel to the central axis. The terms "radial" and "radial" refer to a direction, dimension, or orientation perpendicular to the central axis. The terms "inward" and "inward" refer to a direction, dimension, or orientation that extends radially toward the central axis. The terms "outward" and "outward" refer to a direction, dimension, or orientation that extends radially away from the central axis.

[0013] In the specification, relative terms such as "horizontal", "vertical direction", "upper surface", "lower", "upper surface", and "lower", and their derivatives (e.g., "horizontal", "downward", "downward", "upper surface facing", etc.) should be interpreted as referring to the orientation as described below or as shown in the drawings under discussion. These relative terms are for convenience of description and are not normally intended to require a specific direction.

[0014] Terms regarding attachments, couplings, etc., such as "mounted", "connected", "interconnected", etc., refer to a relationship in which structures are fixed or attached to each other directly or indirectly through intervening structures and through both movable or rigid attachments or relationships, unless specifically stated otherwise.

[0015] FIG. 1 is a cross-sectional view of a glove box system including a door housing 10, a door 12 movably mounted to the door housing 10, and an electronic striker 20 for (i) maintaining the door 12 in a closed and locked state and (ii) releasing the door 12 from the closed and locked state. The door 12 is shown in the closed state in FIG. 1.

[0016] The door housing 10 includes a storage space 14, which is accessible to a user when the door 12 is in an open state and inaccessible to the user when the door 12 is in a closed state (as shown in the figure). The door 12 can also be referred to as an access panel in this specification. The door housing 10 can be, for example, an automotive glove box or an automotive center console. The door housing 10 is not limited to use in an automobile.

[0017] As shown in FIG. 1, the right side of the door housing 10 includes a cutout area that houses an electronic striker 20 (also referred to as the "striker 20" in this specification). The striker 20 includes a flange 21 (FIG. 2A) for receiving a fastener for attaching the striker 20 to the door housing 10.

[0018] As described above, the striker 20 is configured to be attached to the door housing 10, and either a glove box door 12 or a center console door of an automobile is movably attached to the door housing 10. Alternatively, the striker 20 can also be configured to be attached to a glove box door or a center console door. Exemplary glove box doors and door housings are shown in U.S. Patent No. 10,081,970 to Ford and U.S. Patent No. 7,004,517 to Southco, each of which is incorporated by reference in its entirety for all purposes. The striker 20 is configured to hold the door 12 in a latched position and selectively open the door with respect to the door housing 10. The striker 20 is configured to be used with various types of doors and is not limited to use with an automotive glove box.

[0019] Next, referring to the features of the electronic striker 20, FIGS. 2A-3D show the striker 20 in one form or another. The striker 20 is an assembly including a housing 29 including a base 30 and a lid 31 covering the base 30 and attached thereto by fasteners. An internal space is defined between the housing 30 and the lid 31. A series of components described herein are disposed within the internal space to cause movement of the plunger 26 of the electronic striker 20.

[0020] The housing 29 of the striker includes an opening 19 and a passage 22 extending from the opening 19. The opening 19 is defined on the outer surface of the base 30. The plunger 26 forming part of the electronic striker 20 is movably disposed with the passage 22.

[0021] As shown in FIG. 1, the passage 22 and the plunger 26 together interact with a movable pawl 24a extending outwardly from the door 12. The pawl 24a can translate laterally from side to side as depicted by the arrow in FIG. 1. The other pawl 24b moves in synchronization with the pawl 24a, and since the pawls 24 are interconnected by a gear device 25, they move in the opposite translational direction. The pawls 24a and 24b form part of a multi-point latch system. Further details of the pawls 24 including the internal details of the gear device 25 and their multi-point latch system are disclosed in Minnich's U.S. Patent Application No. 62 / 599,162, which is hereby incorporated by reference in its entirety. It should be understood that the gear device 25 is not limited to the gear device disclosed in Minnich's U.S. Patent Application No. 62 / 599,162.

[0022] The passage 22 configured to receive the pawl 24 can be formed within the housing 29 of the striker as shown. Alternatively, the passage 22 for receiving the pawl 24 may be formed in a separate component (not shown) directly or indirectly connected to the housing 29 of the striker.

[0023] Briefly speaking, during operation, the plunger 26 is controlled to move between a retracted position and a deployed position. The plunger 26 of the striker 20 is shown in the deployed position in FIGS. 2A, 2B, 3A, and 3C, while the plunger 26 is shown in the retracted position in FIGS. 2C, 2D, 3B, and 3D.

[0024] In the retracted position of the plunger 26 shown in FIG. 1, the passage 22 can capture and accommodate the pawl 24a of the door 12, thereby holding the door 12 in the closed position (as shown). To capture the pawl 24a of the door 12 by the passage 22, the door 12 must be moved to the closed position (e.g., manually), although not shown, a motor can automatically move the door 12 to the closed position. Once the door 12 is moved to the closed position while the plunger 26 is maintained in the retracted position, the door 12 is held in that position, i.e., the door 12 is locked. When it is desired to unlock the door 12, the electronic striker 20 is operated to move the plunger 26 to the deployed state. When the plunger 26 is moved outward to the deployed position, the pawl 24a is forced to move out of the passage 22, thereby disconnecting the pawl 24a and its door 22 from the electronic striker 20. Immediately thereafter, the door 22 may move to the open position under its own weight. Then, the plunger 26 is returned to the retracted position, at which position the electronic striker 20 is ready to receive the pawl 24a of the door 12.

[0025] In this embodiment, the electronic striker 20 is an active element that moves in response to a user's instruction, while the pawl 24a is a passive element that moves in response to the movement of the electronic striker 20.

[0026] The following describes various active features of the electronic striker 20.

[0027] Next, referring to FIG. 3C, the electric motor 32 of the striker 20 is attached to the base 30. The motor 32 has a rotatable output shaft 34 and a worm 36 connected to the output shaft 34. The worm 36 is non-rotatably connected to the output shaft 34 such that the worm 36 rotates with the output shaft 34. The teeth of the worm 36 mesh with the lower tooth set 39 of the worm gear 38. The upper tooth set 40 of the worm gear 38 meshes with the teeth of the moving gear 42. Also, the teeth of the moving gear 42 mesh with the teeth 46 of the cam lift gear 44. A series of shafts support the respective gears 38, 42, 44, and those shafts are fixedly attached to the base 30.

[0028] In operation, it should be understood that the rotation of the output shaft 34 causes the rotation of the worm 36, which causes the rotation of the worm gear 38, which causes the rotation of the moving gear 42, which causes the rotation of the cam lift gear 44. The gears 36, 38, 42, and 44 can be referred to here as a gear device.

[0029] Next, referring to FIGS. 5A - 5E, the teeth 39 of the worm gear 38 take into account a simple design for ease of molding. Thus, a helical ejector mechanism is not required to form the teeth 39. As background, in a conventional worm gear, each tooth has inclined surfaces on both sides in order to engage the worm in two different rotational directions. One set of inclined surfaces engages the worm in one rotational direction of the worm, and the other set of inclined surfaces engages the worm in the opposite rotational direction of the worm. In the worm gear 38, each tooth 39 has only one inclined surface 41. The inclined surface 41 may be either curved or helical. The surface 43 opposite the inclined surface is substantially planar. Since the gear 38 rotates in a single direction, a simple geometry of the tooth 39 is possible, and thus only the inclined surface 41 is required to engage the teeth of the worm 36. The surface 43 does not necessarily engage the teeth of the worm 36. Also, the teeth 39 do not overlap in the circumferential direction of the worm gear 38.

[0030] Next, referring to FIGS. 4A - 4G and 3B, the cam lift gear 44 includes the teeth 46 on its lower outer periphery, the cam surface 48 on its upper surface, and a protrusion 50 extending radially outward along only a part of the outer periphery of the gear 44.

[0031] The cam surface 48 is a single continuous surface that rises and falls in a direction parallel to the axis of rotation of the gear 44. The cam surface 48 includes a gentle slope 48a, which is followed by a steeply inclined surface portion 48b that joins the gentle slope 48a when viewed circumferentially and along the axis of rotation. When viewed circumferentially, the gentle slope 48a slopes in an upward direction toward the upper end of the gear 44, while the steeply inclined surface portion 48b slopes in a downward direction (i.e., toward the teeth 46) toward the lower end of the gear 44. The absolute value of the slope of the surface portion 48b is greater than that of the portion 48a. The gentle slope 48a constitutes about 75% (or more) of the circumference of the gear 44, while the steeply inclined surface portion 48b constitutes about 25% (or less) of the circumference of the gear 44. In other words, the steeply inclined surface portion 48b constitutes about 90 degrees of the circumference of the cam surface 48, and the portion 48a constitutes about 270 degrees. As will be described later, the cam surface 48 of the gear 44 interacts with a pin 54 extending from the spring - biased plunger 26 to translate the plunger 26 in an outward direction parallel to the axis of rotation of the gear 44.

[0032] The protrusion 50 of the gear 44 is an indexing surface having an inclined path with a curved inlet surface 50a, a flat running surface, and a curved outlet surface when viewed circumferentially. As will be described later, the protrusion 50 interacts with the wiper 57 (FIG. 3A) of the electronic switch 56 to control the rotation of the motor 32, thereby controlling the movement of the plunger 26.

[0033] The protrusion 50 can here be referred to as indexing means. As an alternative to the protrusion, those skilled in the art will recognize that the indexing means can be, for example, a surface, a recess, a marking, a magnet, a circuit, a magnetic property, an optical property, a post, a slot, or a pin on the gear 44, or other features that can be used to track the movement of the gear 44. Also, the indexing means can be provided on different gears of the gear device.

[0034] Next, referring to FIGS. 3B and 3C, the plunger 26 of the electronic striker 20 is an elongated rectangular housing having an upper surface 26a, an opposing lower surface 26b, and four elongated side walls extending between the upper surface 26a and the lower surface 26b. The lower surface 26b includes a flange 26c extending around the perimeter. A square peg 60 extends perpendicularly from one of the elongated side walls of the plunger 26. The peg 60 is dimensioned and configured to move within a slot 64 formed in the base 30. The slot 64 prevents rotation of the plunger 26. A stopper 66 is disposed within the slot 64 to prevent the plunger 26 from moving further than the retracted position and disengaging from the base 30. Similarly, a stopper surface is formed on the base 30 to prevent the plunger 26 from moving further than the deployed position and detaching from the base 30. The plunger 26 is configured to translate in a direction parallel to the axis of rotation of the gear 44 and, optionally, to move in a direction perpendicular to the axis of rotation of the output shaft 34 of the motor 32 for space-saving purposes.

[0035] A pin 54 extends perpendicularly from another side surface of the elongated side walls of the plunger 26. The pin 54 is positioned to extend over the cam surface 48 of the gear 44. Rotation of the cam surface 48 causes translation of the pin 54 and its plunger 26, as will be described in more detail below. Therefore, the cam surface 48 can be referred to as a cam in this specification, and the pin 54 can also be referred to as a cam follower in this specification.

[0036] A compression spring 62 is disposed within the slot 64 together with the peg 60. The spring 62 is attached to or supported by a protrusion 63 on the lower surface of the peg 60. Specifically, one end of the spring 62 is supported on the protrusion 63, and the opposing end of the spring 62 is supported on a similar peg or other surface defined on the base 30, thereby capturing the spring 62 within the slot 64. The spring 62 is biased to move the peg 60 (and thus the plunger 26) toward the retracted state shown in FIG. 1. The spring 62 is also biased to move the pin 54 relative to the cam surface 48 of the gear 44.

[0037] The electronic switch 56 is configured to detect the rotation of the gear 44 and communicate one or more rotational positions of the gear 44 to the processor and / or controller of the striker 20. The switch 56, processor and / or controller can be disposed on the circuit board 70 as shown in FIGS. 3C and 3E. The circuit board 70 can further include a storage device, a power supply, and / or a receiver / transmitter. The switch 56 can generally be referred to as a sensor, and the switch 56 can be replaced, for example, with a rotary encoder, a Hall effect sensor, a linear variable differential transformer (LVDT), a potentiometer, an optical proximity sensor, a transducer, an eddy current sensor, or a photodiode.

[0038] Next, referring to an exemplary method of moving the striker 20, FIGS. 11A-11E show the continuous movement of the plunger 26 towards the retracted position (FIG. 11A), the deployed position (FIG. 11D), and back to the retracted position (FIG. 11E). The door 12 initially starts in a closed and locked state (not shown), where the claws 24 are positioned within their respective passages 22 and the plunger 26 is in the retracted state (as shown in FIGS. 1, 2A, 3C, and 11A). Note that in the closed state of the opening / closing door 12, it may not be possible to open the opening / closing door 12.

[0039] To open door 12, the user, for example, touches, activates, or depresses a remotely located button, switch, or icon 80. The remotely located button, switch, or icon 80 schematically shown in FIG. 1 is connected to a circuit board 70 by either a wireless or a wired connection. The button, switch, or icon 80 can be disposed, as non-limiting examples, on a remote control device, a dashboard, or a touch screen of a vehicle. Activating the remotely located button, switch, or icon 80 causes the controller of striker 20 to activate motor 32. Motor 32 then rotates output shaft 34, which causes gears 36, 38, 42, and 44 to rotate. Specifically, motor 32 rotates gear 44 by one revolution so as to be detected and permitted by switch 56.

[0040] Next, referring to FIGS. 3A and 11A, prior to the rotation of gear 44 in the direction of the arrow depicted in FIG. 3A, first, gear 44 is positioned such that pin 54 is positioned at a low lift position 48d on cam surface 48 corresponding to the retracted position of plunger 26. Also, wiper 57 of switch 56 is positioned either on the curved inlet surface 50a of protrusion 50 of gear 44 or in the vicinity thereof. As gear 44 rotates, pin 54 rides up on the ramp 48a of cam surface 48 of gear 44 against the bias of spring 62. As a result, plunger 26 moves outward toward the deployed state, thereby moving pawl 24a out of passage 22. In other words, plunger 26 pushes pawl 24a out of passage 22 as opposed to other known solutions where a member pulls the pawl out of the passage. The other pawl 24b also moves out of its passage 22 due to gear device 25 between pawls 24a and 24b. As shown in FIG. 11D, pin 54 ultimately reaches the highest lift position 48c on cam surface 48, at which point plunger 26 is positioned in the fully deployed position. Plunger 26 then pushes pawl 24a almost or completely out of passage 22. At this time, door 12 assumes the open position under its own weight.

[0041] Without stopping, motor 32 continues to rotate gear 44 in the same direction. Next, as shown in FIG. 11E, pin 54 then slides down the steeply inclined surface portion 48b of cam surface 48 under the bias of spring 62 and finally reaches the lowermost up-and-down position 48c on cam surface 48. At this point, plunger 26 is in the retracted position shown in FIG. 1. In the retracted position of plunger 26, passage 22 is ready to receive the pawl 24a of door 12 again. Gear 44 continues to rotate until wiper 57 of switch 56 is positioned on either the curved inlet surface 50a of the protrusion 50 of gear 44. When wiper 57 encounters inlet surface 50a, switch 56 sends a signal indicating that gear 44 has rotated one full turn to the controller of striker 20. As a result, the controller stops motor 32. At this point, plunger 26 remains in the retracted position so that passage 22 is ready to receive the pawl 24a of door 12 again. From start to finish, gear 44 rotates one full turn.

[0042] In the event of a power failure, plunger 26 can remain in the retracted position, and as a result, the glove box can be kept locked. To unlock the glove box during a power failure or other situation that requires manual operation priority of striker 20, the user can push the tip 26b (see FIG. 2B) of plunger 26 against the bias of spring 62 to release the pawl 24a from its passage 22. The vehicle can include a removable inspection access panel on the dashboard, for example, to allow the user to access the tip 26b of plunger 26. Note that in the retracted state of plunger 26, the tip 26b of plunger 26 extends from the opening in the lid 31 (see FIG. 2B) of housing 29 and is exposed, so that plunger 26 is accessible to the user.

[0043] The above description of operating striker 20 is not limited to any particular step or sequence of steps and it should be understood that variations may occur which are different from those illustrated and described without departing from the scope and spirit of the invention.

[0044] Preferred embodiments of the present invention have been shown and described herein, it being understood that such embodiments are provided by way of example only. Without departing from the spirit of the present invention, numerous variations, modifications and substitutions will occur to those skilled in the art.
