The present disclosure relates generally to battery packs for portable electronic devices, and more particularly, to a battery pack with a connector mechanism configured to interconnect with a corresponding connector of a portable electronic device and thereby provide extended energy to the electronic device, while also providing a seal at the interconnection that maintains the waterproof integrity of the portable electronic device.
A battery pack for electrically coupling with and securing to a portable electronic device having a device connector and one or more user interface components includes an electronics section and a latch section. The electronics section includes a battery compartment configured to hold one or more batteries and a connector mechanism configured to interconnect with and form a waterproof seal around the device connector. The latch section is pivotably coupled to the electronics section and configured to pivot relative to the electronics section to transition the battery pack between open and closed states. In the open state, the electronics section and the latch section form an open frame structure configured to enable installation of the portable electronic device in the battery pack. In the closed state, the electronics section and the latch section form a closed frame structure configured to secure the portable electronic device within an opening defined by the closed frame structure.
In one configuration, the electronics section includes a base portion that includes the battery compartment, and a side portion that includes the connector mechanism. The side portion extends in a generally orthogonal direction from the base portion and the connector mechanism extends in a general orthogonal direction from the side portion in the direction of the opening formed by the closed frame structure. Due to the positioning of the connector mechanism on the interior side of the battery pack, interconnection between the connector mechanism and the device connector is enabled during installation of the portable electronic device in the battery pack. In another aspect of this configuration, the connector mechanism of the battery pack extends outward from a surface of the electronics section and is configured such that a connector of the connector mechanism is capable of articulating in at least one direction relative to the surface of the electronics section.
In another configuration, the electronics section includes a base portion that includes the battery compartment, and a side portion that includes a port extending therethrough and a flexible cable that is coupled to the connector mechanism. The side portion extends in a generally orthogonal direction from the base portion. The connector mechanism and port are configured to allow for insertion and removal of the connector mechanism relative to the port. In this configuration, while the connector mechanism is positioned on the exterior of the battery pack, the port provides the connector mechanism access to the interior side of the pack. Accordingly, interconnection between the connector mechanism and the device connector is enabled either during or after installation of the portable electronic device in the battery pack.
In one aspect, the connector mechanism of the battery pack includes a connector configured to interconnect with the device connector and a plug surrounding a portion of the connector. The plug is configured to mate with and sealingly engage with the perimeter walls of a recessed well surrounding the device connector to thereby provide the waterproof seal around the device connector. The plug is sized and configured to flex and compress to allow for insertion into the recessed well, as well as subsequent expansion against the perimeter walls. In one embodiment, the plug is formed of a thermoplastic polyurethane (TPU).
In another aspect, one or more of the electronics section and the latch section comprise one or more features configured to provide direct access to the one or more user interface components of the portable electronic device, when the battery pack is in a closed state. For example, the feature may be an opening that aligns with a button or port of the portable electronic device to provide direct access thereto, unimpeded any part of the battery pack. In another example, the feature may be a notch or channel formed in a surface of one of the electronics section and the latch section that aligns with a sensory input or output, e.g., microphone or speaker, of the portable electronic device to allow for direct access thereto, unimpeded any part of the battery pack.
Regarding direct access provided through an opening of the battery pack, in one configuration, the battery pack further includes a cap configured to sealingly engage with the perimeter of the opening to thereby provide a waterproof seal around the opening. This is beneficial in cases where a waterproof cap of the portable electronic device that usually covers an electrical connector of the device, such as a USB connector, is removed from the device in order to install the device in the battery pack. The cap of the battery pack provides the waterproof protection that would otherwise be provided by the device cap.
In another aspect, the electronics section of the battery pack includes a track having one or more mechanical features, wherein the track is configured to allow for receiving and securing an interchangeable mounting structure. In one embodiment, the one or more mechanical features comprise at least one notch configured to engage with at least one protrusion of the mounting structure.
Various aspects of battery packs will now be presented in the detailed description by way of example, and not by way of limitation, with reference to the accompanying drawings, wherein:
In the following detailed description, only certain exemplary embodiments of the present invention are shown and described, by way of illustration. As those skilled in the art would recognize, the invention may be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein. The description and drawings merely illustrate the principles of various embodiments. It will thus be appreciated that those skilled in the art will be able to devise various arrangements that, although not explicitly described or shown herein, embody the principles herein and in the claims and fall within the spirit and scope of the disclosure. Furthermore, all examples recited herein are principally intended to aid the reader in understanding the principles of the embodiments, and are to be construed as being without limitation to such specifically recited examples and conditions. Moreover, all statements herein reciting principles, aspects, and embodiments, as well as specific examples thereof, are intended to encompass equivalents thereof.
Disclosed herein in a battery pack that provides extended energy to portable electronic devices while preserving the functionality, integrity and user experience of the devices. The portable electronic device may be a camera that includes various interface components, such as operation buttons, a lens, a display, connector ports, speakers, microphones, that are associated with various sides or faces of the device. The portable electronic device may also be configured as a waterproof device that provides a seal against the ingress of water to the internal components of the electronic device up to certain depth. For example, the portable electronic device may be a GoPro HERO5 or HERO6 camera that is waterproof up to a depth of 33 feet.
The battery pack comprises a frame structure or casing that establishes a waterproof electrical interconnection between an energy source housed within the battery pack and the portable electronic device, to thereby maintain the specified waterproof integrity of the device. The frame structure of the battery pack is configured to transition between an open state that allows for easy installation and interconnection of the portable electronic device, and a closed state that secures the portable electronic device within the battery pack. Features, e.g., openings, notches, holes, included in the frame structure provide a user direct access to the various interface components of the portable electronic device.

The maximum height 702, maximum width 704 and maximum depth 703 of the opening 124 are greater than the maximum height, maximum width and maximum depth of the portable electronic device to be installed in the battery pack. The amount by which the maximum dimensions of the opening 124 are greater than the maximum dimensions of the portable electronic device is generally small, on the order of a millimeter, which allows for a tight fit between the portable electronic device and the closed frame structure that prevents or significantly restricts side-to-side, up-and-down, and back-and-forth movement of the device within the closed frame structure.
The opening 124 may also be characterized by a minimum height 706 and a minimum width 708 that are less than the maximum height and the maximum width of the portable electronic device. As best shown in

The battery pack 102 thus disclosed in
In the configuration of
The connector mechanism 106 includes a connector 802, e.g., a C-type USB connector, a seal 804, a flexible mount 806, a holder 808, and a printed circuit board 810. The connector 802 is configured to mate and interconnect with a corresponding connector receptacle of the portable electronic device 104 and is electrically and mechanically coupled to the printed circuit board 810. The seal 804 is formed of a thermoplastic polyurethane (TPU) and is dimensioned and configured to fit within a recessed well of the portable electronic device 104 that surrounds the connector receptacle, and to form a water tight seal along the perimeter of the recessed well. The flexible mount 806 is also formed of TPU and may be configured to allow for the other components of the connector mechanism 106 to flex or articulate relative to the electronics section 108. Each of the seal 804 and flexible mount 806 are secured to an outer surface of the holder 808. The seal 804 forms a plug that surrounds the connector 802.
Each of the connector 802 and printed circuit board 810 extend at least partially through a hole in the holder 808. The holder 808 is formed of a rigid plastic and secures the connector 802 in place relative to the seal 804 and flexible mount 806. The back surface of the flexible mount 806 is bonded to the electronics section 108, which is formed of rigid plastic. The printed circuit board 810 of the connector mechanism 106 is electrically connected to a printed circuit board 906 of the electronics section 108 through a flexible ribbon cable 908. Enough slack may be present in the ribbon cable to allow for the printed circuit board 810 of the connector mechanism 106 to move relative to the printed circuit board 906 of the electronics section 108.
The connector mechanism 106 has a central axis 902 that extends along the length of the connector. In
A connector mechanism 106 configured to articulate as thus described is beneficial in that it reduces the possibility of damage to either of the electronic-device connector and the battery-pack connector during installation of the portable electronic device 104 or during use of the device. For example, during installation, while the portable electronic device 104 is being slid into place, the connector of the device may not perfectly align with the connector of the battery pack. As the electronic-device connector engages the battery-pack connector, misalignment of the respective connectors may be compensated for by the flexibility of the battery pack connector, which flexibility allows the connector to articulate into alignment with the electronic-device connector. Likewise, after the portable electronic device 104 is installed in the battery pack, the electronic device and the battery pack may experience sudden movement that may cause the device body to slightly shift within the battery-pack frame. The flexibility of the battery-pack connector allows for the battery-pack connector to move relative to the battery-pack frame and maintain alignment with the electronic-device connector; thereby reducing the possibility of damage that would otherwise occur if the battery-pack connector was rigidly fixed in place within the battery-pack frame. Furthermore, the flexible mount 806 itself is configured to reduce stress on the battery-pack connector during shocks that may occur during ordinary use of the battery pack, including for example, from dropping of the battery pack or high-G movements of the battery pack.
Each of the connector 1402 and printed circuit board 1410 extend at least partially through a hole in the semi-rigid overmold 1408. The semi-rigid overmold 1408 is formed of a rigid plastic and secures the connector 1402 in place relative to the seal 1404. The semi-rigid overmold 1408 includes electrical components, e.g., wires, cables, etc., that electrically connect with the printed circuit board 1410 at one end and with electrical components of the battery compartment at the other end. The back surface of the seal 1404 is bonded to a protrusion 1406 that is molded into the electronics section 108. The semi-rigid overmold 1408 fits into the protrusion 1406. A gap 1412 between the inner wall of the protrusion 1406 and the outer surface of the semi-rigid overmold 1408 may be included to allow for the semi-rigid overmold 1408 and other components of the connector mechanism to articulate relative to the electronics section 108 in the same manner as described above with reference to the first embodiment of the connector mechanism.
Each of the connector 1602 and printed circuit board 1610 extend at least partially through the connector sleeve 1606 which extends through a hole in the seal/boot 1604. The connector sleeve 1606 is formed of a rigid plastic and secures the connector 1602 in place relative to the seal/boot 1604.
The connector mechanism 106 includes a connector 1802, e.g., a C-type USB connector, a flexible single-piece seal/boot 1804, a holder 1808, and a printed circuit board 1810. The connector 1802 is configured to mate or interconnect with a corresponding connector receptacle of the portable electronic device 104 and is electrically and mechanically coupled to the printed circuit board 1810. The seal/boot 1804 is formed of a thermoplastic polyurethane (TPU) and is dimensioned and configured at a first end 1812 to fit within a recessed well of the portable electronic device 104 that surrounds the connector receptacle of the portable electronic device 104, and to form a water tight seal along the perimeter of the recessed well. The seal/boot 1804 is secured, e.g., bonded, to the electronics section 108 at a second end 1806. The seal/boot 1804 may also be configured to allow for the other components of the connector mechanism 106 to flex or articulate relative to the electronics section 108 in the same manner as described above with reference to the first embodiment of the connector mechanism.
The connector 1802 and printed circuit board 1810 extend at least partially through the holder 1808. The printed circuit board 1810 extends into the electronics section 108 where it is electrically coupled to a printed circuit board (not shown) by a flexible ribbon cable (not shown). The holder 1808 is formed of a rigid plastic and secures the connector 1802 and printed circuit board 1810 in place relative to the seal/boot 1804. The holder 1808 includes a pivot structure 1814 that is configured to engage a pivot structure 1816 of the electronics section 108. In the configuration shown in
The connector mechanism 106 has a central axis 902 that extends along the length of the connector. In
In this configuration, the electronics section 2414 includes a base portion 2416 that includes the battery compartment, and a side portion 2418 that includes a port 2420 extending therethrough and a flexible cable 2410 that is coupled to the connector mechanism 2404. The side portion 2418 extends in a generally orthogonal direction from the base portion 2416. The connector mechanism 2404 and port 2420 are configured to allow for insertion and removal of the connector mechanism relative to the port. In this configuration, while the connector mechanism 2404 is positioned on the exterior of the battery pack 2402, the port 2420 provides the connector mechanism access to the interior side of the pack. Accordingly, interconnection between the connector mechanism 2404 and the device connector 2408 is enabled either during or after installation of the portable electronic device 104 in the battery pack.
Each of the interchangeable mounts is configured the same, except for the mount structure. The mounts 2602, 2604 are dimensioned to fit within a track 2616 located at the bottom of the portable electronic device 104104. The mounts include a longitudinal cut out 2608 at one end that forms two opposing arms 2618a, 2618b. Associated with each arm 2618a, 2618b is a grip protrusion 2606a, 2606b and a first end stop 2612a, 2612b. A second end stop 2610 is at the opposite end of the mount.
A mount 2602, 2604 is installed by sliding the second end stop 2610 into the track 2616 at a first end 2620 of the track until the grip protrusion 2606a, 2606b abut the edges 2622a, 2622b of the track 2616, which thereby prevents further sliding of the mount. The opposing grip protrusions 2606a, 2606b may then be squeezed towards each other, which in turn causes the opposing arms 2618a, 2618b to move towards each other. This squeezing displaces the grip protrusions 2606a, 2606b inward relative to the edges 2622a, 2622b of the track 2616 and toward the middle of the track where the protrusions no longer abut the edges. As such, the mount 2602, 2604 may slide further along the track 2616 until the grip protrusions 2606a, 2606b align with corresponding notches 2614a, 2614b of the track 2616. Upon such alignment, the grip protrusions 2606a, 2606b snap into place in the notches 2614a, 2614b thereby securing the mount 2602, 2604 to the battery pack 102. The mount 2602, 2604 may be removed by squeezing the grip protrusions 2606a, 2606b toward each other and sliding the mount out along the track 2616.
The front case 2804 includes a front opening 2814 with a perimeter gasket 2816. The opening 2814 is sized to receive a portion 2818 of the portable electronic device 2820 and sealingly engage with it to form a waterproof seal. For example, the opening 2814 may receive the lens portion 2818 of a camera. The front case 2804 also includes one or more membrane buttons 2822a, 2822b, each configured to provide a waterproof interface through which the user may interact with a corresponding operation button 2824a on the portable electronic device 2820.
The battery pack 2802 includes a battery unit 2826 having a dongle connector 2828 electrically coupled thereto. The dongle connector 2828 includes a connector 2830 configured to interconnect with a connector receptacle 2832 of the portable electronic device 2820. Upon connection of the battery unit 2826 to the portable electronic device 2820, the device rests on top of the battery unit and together, the unit and device may be securely placed within the front case 2804. To this end, the battery unit 2826 is sized and contoured to fit within the bottom region of the front case 2804 in a manner that prevents or significantly restricts side-to-side movement of the battery unit. To further assist in properly positioning and securing the battery unit 2826 in place within the front case 2804, the internal surfaces of the front case may include one or more alignment features, e.g., grooves or protrusions, that mate with or align with corresponding features of the battery unit.
The portable electronic device 2820 is secured in place in the upper portion of the front case 2804 through placement of the portion 2818 of the device in the opening 2814 of the front case, which prevents or significantly restricts side-to-side movement of the device. Closing of the back case 2806 relative to the front case 2804 causes respective perimeter gaskets of the cases to abut each other to provide a waterproof enclosure that encases the battery unit 2826 and the portable electronic device 2820. The internal dimensions of the enclosure, including for example, the distance between the inside surfaces of the front case 2804 and the back case 2806, form a tight fit with the portable electronic device 2820 and the battery unit 2826 that prevents or significantly restricts back-and-forth movement of the device and battery unit within the battery pack 2802.
