Description
FIELD OF THE DISCLOSURE

The present disclosure generally relates to mechanical dampers for portable electronic devices, and more particularly to a low profile rotary damper for use within portable electronic devices.


BACKGROUND

Many portable electronic devices comprise displays that can be moved independently from the keyboard or vice versa. For example, these devices usually allow the display to slide in a linear direction with respect to the keyboard. Conventional mechanisms currently used to provide this type of movement generally include bumpers that stop the movement of the display or keyboard at a designated location. This configuration can be problematic because the bumpers can be easily damaged or compromised when the device is dropped or when too much force is exerted on the bumpers when moving the display/keyboard.

DETAILED DESCRIPTION

As required, detailed embodiments are disclosed herein; however, it is to be understood that the disclosed embodiments are merely examples and that the systems and methods described below can be embodied in various forms. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the disclosed subject matter in virtually any appropriately detailed structure and function. Further, the terms and phrases used herein are not intended to be limiting, but rather, to provide an understandable description.


The terms “a” or “an”, as used herein, are defined as one or more than one. The term plurality, as used herein, is defined as two or more than two. The term another, as used herein, is defined as at least a second or more. The terms “including” and “having” as used herein, are defined as comprising (i.e. open language). The term “coupled” as used herein, is defined as “connected” although not necessarily directly, and not necessarily mechanically.


The term “wireless communication device” is intended to broadly cover many different types of devices that can wirelessly receive signals, and in most cases can wirelessly transmit signals, and may also operate in a wireless communication system. For example, and not for any limitation, a wireless communication device can include any one or a combination of the following: a two-way radio, a cellular telephone, a mobile phone, a smartphone, a two-way pager, a wireless messaging device, a laptop/computer, a personal digital assistant, and other similar devices.


The term “portable electronic device” is intended to broadly cover many different types of electronic devices that are portable. For example, and not for any limitation, a portable electronic device can include any one or a combination of the following: a wireless communication device, a laptop computer, notebook computer, personal computer, Personal Digital Assistant, tablets, and other handheld electronic devices that can be carried on one's person.


Described below is a dampening assembly or low profile rotary damper for a portable electronic device such as, but not limited to a wireless communication device. The dampening assembly comprises a housing. The housing includes a top portion and a bottom portion. A pivot arm is pivotably coupled to the bottom portion of the housing. A reservoir is defined between the top portion and the bottom portion. The reservoir comprises at least one of a fluid and a viscous material. A first portion of the pivot arm is disposed within the reservoir. A second portion of the pivot arm extends through and above the top portion of the housing.


The low profile rotary damper provides a dampening force that reduces the velocity of a slide mechanism when approaching the end of its travel. This reduction in velocity reduces the force exerted on bumpers of the slide mechanism at the end of travel and also reduces any noise generated as the slide mechanism comes to a stop. The low profile rotary damper, in one example, comprises a reservoir that is filled with a fluid or viscous material. As the slide mechanism is moved in a linear direction a portion of the slide mechanism exerts a force on a pivoting member of the low profile rotary damper. As the pivoting member is rotated, a portion of the pivoting member passes through the fluid or viscous material within the reservoir, thereby exerting a force on this portion of the pivoting member. This force is translated back to the slide mechanism, thereby providing a dampening effect that reduces the velocity of travel of the slide mechanism. The force exerted against the slide mechanism is a function of the velocity of travel (e.g., the higher the velocity, the higher the force).


Various materials or combinations of materials can be used to construct the low profile rotary damper and its components. For example, materials such as plastics, metals, metal alloys, composites, ceramics, and other inorganic or organic materials or combinations thereof may be used.


Low Profile Rotary Damper



FIG. 1 is an exploded view of a low profile rotary damper assembly 100 according to one example. The damper assembly 100 comprises a housing 102 that includes a bottom portion 104 and a top portion 106. A sealing member 108, such as a gasket, is disposed between the bottom and top portions 104, 106 of the housing 102. A first portion 110 of a pivot arm 1001 (FIG. 10) is also disposed between the bottom and top portions 104, 106 of the housing 102. A second portion 112 of the pivot arm 1001 is disposed within a first cavity 320 (FIG. 3) defined in the top portion 106 of the housing 102 and mates with the first portion 110 of the pivot arm 1001. A sealing member 116 such as, but not limited to, an o-ring is also disposed within the first cavity 320.



FIG. 2 shows a top-side view of the bottom portion 104 of the housing 102. The bottom portion 104 acts as a base member for the housing 102. The bottom portion 104 comprises a substantially curved configuration, where a first side 202 and a second side 204 angle outwards away from a center of the bottom portion 104. A third side 206 couples the first side 202 to the second side 204 and curves outward from the center of the bottom portion 104.


The bottom portion 104 comprises a top surface 208 and a bottom surface 210. The top surface 208 comprises a second recessed area 212 that comprises a substantially curved configuration. More specifically, the second recessed area 212 is recessed into the top surface 208 towards the bottom surface 210. For example, a first side 214 and a second side 216 of the second recessed area 212 angle outwards away from a center of the second recessed area 212. A third side 218 couples the first side 214 to the second side 216 and curves outward from the center of the second recessed area 212. In this example, the first side 214 of the recessed area corresponds to the first side 202 of the bottom portion 104, the second side 216 of the second recessed area 212 corresponds to the second side 204 of the bottom portion 104, and the third side 218 corresponds to the third side 206 of the bottom portion 104.


The second recessed area 212 comprises a vertical member 220 that extends above the top surface 208 of the bottom portion 104. The vertical member 220 comprises an outer wall 222 and an inner wall 224 that defines a cavity 226. The cavity 226 is configured to receive a fastening member 118 (FIG. 1) such as, but not limited to, a screw, a bolt, a rivet, or the like. The fastening member 118 retains the second portion 112 (and hence the first portion 110) of the pivot arm 1001 around vertical member 220. The bottom portion 104 also comprises a first plurality of fastening areas 228, 230, 232, 234 that correspond to a plurality of fastening areas 302, 304, 306, 308 (FIG. 3) disposed on the top portion 106 of the housing 102. These fastening areas 228, 230, 232, 234 and 302, 304, 306, 308 are configured to receive fastening members 120, 122, 124, 126 (FIG. 1) such as, but not limited to, a screw, a bolt, a rivet, or the like for coupling the bottom portion 104 of the housing 102 to the top portion 106 of the housing. It should be noted that the gasket 108 is disposed between the bottom and top portions 104, 106 of the housing 102 to provide a seal between the two portions 104, 106.


The bottom portion 104 also comprises a second plurality of fastening areas 236, 238 that are configured to receive a set of fastening members for coupling a guide base/plate 402 (FIG. 4) of a slide mechanism 1003 (FIG. 10) to the bottom portion 104. This second plurality of fastening areas 236, 238 are disposed on a portion 240, 242 of the first and second sides 202, 204 that extend out and away from the corresponding first and second sides 310, 312 (FIG. 3) of the top portion 106. In other words, these exposed portions 240, 242 of the first and second sides 202, 204 of the bottom portion 104 of the housing 102 do not touch the top portion 106.



FIG. 3 shows a bottom-side view of the top portion 106 of the housing 102. As can be seen, the top portion 106 of the housing 102 comprises a configuration that substantially corresponds to the bottom portion 104 of the housing 102 discussed above. When the top portion 106 is disposed on top of and coupled to the bottom portion 104, the bottom surface 314 of the top portion 106 abuts the top surface 208 of the bottom portion 104. In addition to the fastening areas 302, 304, 306, 308 discussed above, the top portion 106 also comprises a set of mating areas 309, 311 that are configured to receive a set of vertical mating members 244, 246 (FIG. 2) disposed on the top surface 208 of the bottom portion 104. These mating areas 309, 311 and mating members 244, 246 provide additional rigidity to the housing 102.


The top portion 106 also comprises a first recessed area 316 that substantially corresponds to at least a portion of the second recessed area 212 disposed on the bottom portion 104. The first recessed area 316 of the top portion 106 is recessed into the bottom surface 314 towards a top surface 318 of the top portion 106. The second recessed area 212 of the bottom portion 104 of the housing 102 and the first recessed area 316 of the top portion 106 of the housing 102 form a reservoir for retaining a fluid or viscous material therein such as, but not limited to, oil, grease, or the like.


A first cavity 320 extends through the top surface 318 of the top portion 106 to the bottom surface 314 of the top portion 106. This first cavity 320 is configured to receive the vertical member 220 of the bottom portion 104 of the housing 102. The diameter of the first cavity 320 is larger than the diameter of the vertical member 220. The first cavity 320 comprises an inner edge 322 that traverses the first cavity 320. The inner edge 322 defines a first portion 324 of the first cavity 320 between the top surface 318 of the top portion 106 of the housing 102 and a top surface 902 (FIG. 9) of the inner edge 322. The inner edge 322 also defines a second portion 326 of the first cavity 320 between a bottom surface 328 of the inner edge 322 and the bottom surface 314 of the bottom portion 104 of the housing 102. The diameter of the inner edge 322 is smaller than the diameter of the first portion 324 of the first cavity 320 and the second portion 326 of the first cavity 320.


The geometry of the bottom portion 104 of the housing 102 substantially conforms to a cut-out area 404 of the guide base 402. For example, FIG. 4 shows one example of the guide base 402 that comprises a cut-out area 404 corresponding to the housing 102 of the damper assembly 100. In one example, the guide base 402 remains stationary while a slide plate (e.g., a transitioning member) 502 (FIG. 5) slides along the guide base 402. The slide plate 502 comprises an engagement area 504 or member that engages a portion of the pivot arm 1001 and transitions the portion (e.g., display) of a portable electronic device coupled thereto in a linear direction as the slide plate 502 slides along the stationary base 402. In one example, this engagement area 504 is a cut-out area that engages an outer wall 830 of the vertical engagement member 828 (FIG. 8) of the second portion 112 of the pivot arm. However, other configurations are also applicable as well. It should be noted that one or more examples of the present disclosure are also applicable to portable mechanical devices as well.


In one example, the base 402 is disposed over the housing 102 such that at least a region of the top portion 106 of the housing 102 extends above a top surface 403 of the guide base 402. The guide base 402 comprises a set of fastening areas 406, 408 that corresponding to the second plurality of fastening areas 236, 238 of the bottom portion 104 of the housing 102. When the guide base 402 is coupled to the housing 102 a bottom surface 410 of the guide base 402 abuts the exposed portions 240, 242 of the first and second sides 202, 204 of the bottom portion 104 of the housing 102.


As discussed above, the pivoting arm 1001 comprises a first portion 110 and a second portion 112. FIGS. 6-7 show various examples of the first portion 110 of the pivot arm. FIG. 6 shows that the first portion 110 comprises a first annular member 602 that comprises a first outer wall 604 and a first inner wall 606. The first inner wall 606 defines a second cavity 608 that is configured to receive the vertical member 220 of the bottom portion 104 of the housing 102. One or more portions of the first outer wall 604 comprise a recessed area 614, 616 that is configured to mate with a corresponding portion 816, 818 (FIG. 8) of the second portion 112 of the pivot arm 1001. A first elongated member 620 extends outward in a lateral direction from the first outer wall 604 of the first annular member 602. The first elongated member 620 comprises an extended region 622 that extends above a top surface 624 of the first annular member 602.



FIG. 7 shows another example of the first portion 110 of the pivot arm 1001. FIG. 7 shows that the first portion 110 comprises an annular member 702 that includes an outer wall 704 and an inner wall 706. The inner wall 706 defines a third cavity 708 that is configured to receive the vertical member 220 of the bottom portion 104 of the housing 102. One or more portions 710, 712 of the outer wall 704 comprise a recessed area 714, 716 that is configured to mate with a corresponding portion 816, 818 (FIG. 8) of the second portion 112 of the pivot arm 1001. An elongated member 720 extends outward in a lateral direction from the first outer wall 604 of the first annular member 602. The elongated member 720 comprises an extended region 722 that extends above a top surface 724 of the annular member 702. In the example of FIG. 7 a top surface 726 of the extended region 722 comprises a recessed area 728. A bottom surface 730 of the extended region 722 comprises a recessed area 732 that corresponds to the recessed area 728 of the top surface 726.


As the pivot arm 1001 pivots about the vertical member 220 of the bottom portion 104 of the housing 102, the extended region 622 of the first elongated member 620 (or the extended region 722 of the elongated member 720) is rotated through the fluid or viscous material in the reservoir. A force is exerted on the extended region 622 by the fluid or viscous material, which is translated to the guide base 402 or slide plate 502 (depending on the given configuration of the slide mechanism 1003) as a dampening force. Therefore, the pivot arm 1001 provides a dampening effect that reduces the velocity of the guide base 402 or slide plate 502 and corresponding first and second portions 401, 501 of a portable electronic device 1000 (FIG. 10) coupled thereto. In one example, the first portion 401 of the portable electronic device 1000 comprises a keyboard (not shown) and the second portion 501 of the device 1000 comprises a display (not shown). However, other configurations are applicable as well.



FIG. 8 shows a top-side view of the second portion 112 of the pivot arm 1001. This second portion 112 of the pivot arm 1001 includes a second annular member 802. The second annular member 802 comprises a second outer wall 804 and a second inner wall 806. A cavity 808 is defined by a first portion 810 of the second inner wall 806 and a second portion 812 of the second inner wall 806. The first and second portions 810, 812 of the second inner wall 806 are coupled to each other via a chamfered region 814 that traverses the second inner wall 806. The diameter of the first portion 810 is larger than the diameter of the second portion 812. The area of the cavity 808 defined by the first portion 810 of the second inner wall 806 is configured to receive a portion of the fastening member 118 that mates with the cavity 226 of the vertical member 220 of the bottom portion 104 of the housing 102. The area of the cavity 808 defined by the second portion 812 of the second inner wall 806 is configured to receive the vertical member 220 of the bottom portion 104 of the housing 102.


One or more mating members 816, 818 extend from the second outer wall 804 beyond a bottom surface 820 of the second annular member 802. These mating members 816, 818 are configured to mate with the corresponding recessed area 614, 616 of the first annular member 602 of the first portion 110 of the pivot arm 1001. A second elongated member 822 extends outward from the second outer wall 804. In one example, a top surface 824 of the second elongated member 822 is substantially flush with a top surface 826 of the second annular member 802. However, other configurations are applicable as well. A vertical engagement member 828 extends from the top surface 824 of the second elongated member 822 and above the top surface 826 of the second annular member 802. In one example, this vertical engagement member 828 engages the engagement area 504 of the slide plate 502 as the slide plate 502 is moved in a linear direction relative to the guide base 402. This area 504 of the slide plate 502 exerts a force on the vertical engagement member 828 that rotates the pivot arm 1001 around the vertical member 220 of the bottom portion 104 of the housing 102.


Turning now to FIG. 9, FIG. 9 shows a side cross-sectional view of the damper assembly 100. As can be seen from FIG. 9, the first inner wall 606 of the first annular member 602 of the first portion 110 of the pivot arm 1001 circumscribes the outer wall 222 of the vertical member 220 of the bottom portion 104 of the housing 102. The second portion 812 of the second inner wall 806 of the second portion 112 of the pivot arm 1001 also circumscribes the outer wall 222 of the first annular member 602 that comprises a first outer wall 604. FIG. 9 also shows that the mating members 816, 818 of the second portion 112 of the pivoting arm 1001 are mated with the corresponding recessed areas 614, 616 of the first portion 110 of the pivot arm 1001. Therefore, as the slide plate 502 exerts a force on the vertical engagement member 828 of the second portion 112 of the pivot arm 1001, the second portion 112 and the first portion 110 are rotated about the vertical member 220 of the bottom portion 104 of the housing 102.


As can be seen in FIG. 9, a top portion 906 of the fastening member 118 extends beyond the vertical member 220 and over a top surface 908 of the chamfered region 814 of the second annular member 802 of the second portion 112 of the pivot arm 1001. A bottom surface 910 of the top portion 906 of the fastening member 118 abuts a top surface 912 of the vertical member 120 and is disposed over the top surface 908 of the chamfered region 814. This prevents the pivot arm 1001 from lifting out of the housing 102. It should be noted that one or more sealing members (not shown) can be disposed between the second portion 112 of the pivot arm 1001 and the top portion 906 of the fastening member 118 to further prevent the fluid or viscous material within the reservoir from escaping.



FIG. 9 further shows that the sealing member 116, in one example, is disposed within the first portion 324 of the first cavity 320 of the housing top portion 106. As can be seen, the sealing member 116 abuts the second outer wall 804 of the second portion 112 of the pivot arm 1001. This prevents any of the fluid or viscous material within the reservoir from escaping through the first cavity 320 of the housing top portion 106. The gasket 108 is disposed between the bottom surface 314 of the top portion 106 of the housing and the top surface 208 of the bottom portion 104 of the housing 102. The gasket 108 creates a seal between the bottom and top portions 104, 106 and prevents the fluid or viscous material within the reservoir from leaking.


Turning now to FIGS. 10-12, FIGS. 10-12 show the portable electronic device 1000 comprising a slide mechanism 1003 with the low profile damper assembly 100 coupled thereto. In one example, the slide mechanism 1003 comprises the guide base 402, slide plate 502, and any components and/or mechanisms that allow the guide base 402 and slide plate 502 to transition with respect to each other. In the example shown in FIGS. 10-12, the low profile damper assembly 100 is coupled to the guide base 402. It should be noted that the example of FIGS. 10-12, show the slide plate 502 being transitioned in a first direction with respect to the guide base 402 while the guide base 402 remains stationary. However, it should be noted that other configurations are applicable as well. The engagement area 504 of the slide plate 502 can be disposed on the slide plate 502 in various locations to accommodate various configurations of the guide base 402 and slide plate 502.



FIG. 10 shows the slide plate 502 in a first or non-extended position with respect to the base 402. FIG. 10 also shows that a first portion 1002 of the engagement area 504 of the slide plate 502 abuts the outer wall 830 of the vertical engagement member 828 when the slide plate 502 is in the non-extended position. As the slide plate 502 is transitioned from a non-extended position to a second or an extended position, the vertical engagement member 828 of the pivot arm 1001 of the damper assembly 100 travels within the engagement area 504 of the slide plate 502. When the slide plate 502 has traveled a predetermined distance or is within a predetermined distance from its end of travel, the vertical engagement member 828 abuts a second portion 1102 of the engagement area 504 that is situated opposite from the first portion 1002 of the engagement area 504, as shown in FIG. 11.


As the slide plate 502 continues to transition to its fully extended position, the second portion 1102 of the engagement area 504 of slide plate 502 exerts a constant force against the outer wall 830 of the vertical engagement member 828. This force causes the pivot arm 1001 to pivot around the vertical member 220 of the bottom portion 104 of the housing 102. This pivoting motion rotates the first elongated member 620 and its extended region 622 of the first portion 110 of the pivot arm 1001 through fluid or viscous material within the reservoir, as shown in FIG. 12. It should be noted that the dampening assembly 100 can be configured to move the pivot arm in a linear motion as compared to a pivoting motion.


As the member 620 and its extended region 622 rotate through the reservoir the fluid or viscous material exerts a force thereon. This force is translated back to the slide plate 502 as a dampening force, thereby reducing the velocity of travel of the slide plate 502. As the slide plate 502 is transitioned back to its non-extended position, the pivot arm of the damper assembly 100 is rotated back to the position shown in FIG. 10 by the first portion 1002 of the engagement area 504 of the slide plate 502. A similar dampening force is exerted by the dampener assembly 100 as that already discussed above with respect to FIG. 12.


As can be seen, the damper assembly 100 provides a dampening force that reduces the velocity of a slide mechanisms as the mechanism reaches a given distance from its end of travel. This reduces the forces experienced by the components of the slide mechanism that are utilized to stop the slide mechanism. Also, undesired noises resulting from the slide mechanism being stopped are reduced or eliminated by the damper assembly 100 since the velocity of the slide mechanism is dampened. Even further, because the velocity of the slide mechanism is dampened at the end of its travel, the user experiences a smoother, more enjoyable sliding motion.
