DETAILED DESCRIPTION
(11) The present disclosure relates to the routing of data and power transmission media, such as FPCs, coaxial cable, wiring, and the like, through rotatable gimbal assemblies used in connection with DICDs. Throughout the present disclosure, the term transmission media should be understood to include any medium suitable for transmitting power and/or digital data, such as digital images and/or digital video. Additionally, the term FPC should be understood to include microflex, high-resolution video cable (e.g., 4 k), and the term wiring should be understood to include electrical wiring, coaxial cable, etc. Moreover, when used in the context of transmission media, the term coiled should be understood as referring to a configuration in which the transmission media is concentrically wound about itself. In contrast, the term uncoiled should be understood as referring to and including any configuration in which the transmission media is not concentrically wound about itself, such as, for example, configurations in which the transmission media extends either in a generally linear manner or a generally non-linear manner, for example, bent, wavy, sinusoidal, etc.
(12) The gimbal systems and assemblies disclosed herein allow for various types of transmission media to pass across and through the interior of the assemblies in a manner that allows for free rotation. As the assemblies rotate, internal guides and structures support and route the transmission media and allow the transmission media to rotate, deflect, and bend in a controlled manner. Throughout the present disclosure, when used as verbs, terms such as direct, guide, and route may be used interchangeably. The various embodiments of the gimbal assemblies disclosed herein permit both coiled and uncoiled routing of transmission media internally through the gimbal assemblies to allow for capitalization on any advantages, and a reduction in any disadvantages, of coiled and uncoiled routing.
(13) Gimbal systems and assemblies according to the present disclosure may find applicability in a wide variety of applications. For example,
(14) With reference now to
(15) The motor assembly 200 includes a motor 202, a motor housing 204 (
(16) The housings 300, 400 accommodate the internal components of the gimbal assembly 100, discussed in further detail below, as well as one or more varieties of transmission media 500, which facilitate, for example, data transfer, power transfer, and/or the communication of control signals to the gimbal assembly 100. In the particular embodiment shown in
(17) Depending upon the intended use and positioning of the gimbal assembly 100, the housings 300, 400 may be oriented vertically (i.e., in upper and lower relation), as illustrated in
(18) As seen in
(19) The arm 302 extends radially outward from the body 304, and defines an internal passage 312 that is configured and dimensioned to receive the transmission media 500, which may include one or more FPCs 502 (
(20) The body 304 of the housing 300 includes a floor 316 (
(21) The guide 308 extends vertically from the body 304 to direct and route the transmission media 500 from the housing 300 into the housing 400. In one embodiment, such as that illustrated in
(22) In the illustrated embodiment, the bracket 310 is shown as being integrally formed with the body 304 of the housing 300, via injection molding, for example, such that the guide 308 extends upwardly from the floor 316 and radially inward from the wall 318. In alternate embodiments, however, it is envisioned that the body 304 and the guide 308 may be discrete structures, and/or that the guide 308 may be spaced inwardly from the wall 318 to create radial separation between the guide 308 and the wall 318.
(23) In the particular embodiment seen in
(24) The base portion 322 extends transversely (i.e., in relation to the vertical height of the base portion 322) in a first direction along a first axis A-A (
(25) Although the base portion 322 and the support 324 are illustrated as being in generally orthogonal relation in the embodiment of the guide 308 seen in
(26) With reference to
(27) The arm 402 extends radially outward from the body 404, and defines an internal passage 410 (
(28) The body 404 of the housing 400 includes a floor 414 (
(29) As seen in
(30) Upon actuation of the motor assembly 200 (
(31) With reference again to
(32) As the guide 308 traverses the channel 424, the transmission media 500 (
(33) The configuration, dimensions, and positions of the components of the gimbal assembly 100, such as the guide 308 (
(34) With reference now to
(35) The gimbal assembly 600 includes a second (upper) housing 700 with an arm 702, and one or more additional guides 702.sub.A, 702.sub.B that cooperate with the guide 308 extending from the first (lower) housing 300 to further assist in routing the transmission media 500 through the gimbal assembly 600. Although shown as including a pair of guides 702.sub.A, 702.sub.B configured as discrete braces 703.sub.A, 703.sub.B, in alternate embodiments, the specific number, location, and/or configurations of the guides 702.sub.A, 702.sub.B may be altered or varied without departing from the scope of the present disclosure. For example, it is envisioned that the gimbal assembly 600 may include a single guide only, such as the guide 702.sub.A.
(36) The guides 702.sub.A, 702.sub.B are oriented such that the transmission media 500 extends between the guides 702.sub.A, 702.sub.B as the transmission media 500 traverses the housing 700. More specifically, the guides 702.sub.A, 702.sub.B define a passage 704 therebetween that is configured and dimensioned to receive the transmission media 500. The guides 702.sub.A, 702.sub.B thus permit routing of the transmission media 500 across the housing 700 into the arm 702 in an uncoiled configuration, as discussed above in connection with the gimbal assembly 100 (
(37) In the illustrated embodiment, each of the guides 702.sub.A, 702.sub.B includes an arcuate configuration defining a curvature that is dimensioned to support the transmission media 500 during relative rotation between the housings 300, 700, and restrain displacement of the transmission media 500 via receipt within the passage 704. The arcuate configurations of the guides 702.sub.A, 702.sub.B facilitate bending or other such deformation in a predetermined, controlled manner. By restraining the transmission media 500 and controlling the manner and extent to which the transmission media 500 bends, the likelihood of kinking, twisting, or other such undesirable deformation can be reduced, thereby potentially increasing the usable life of the transmission media 500. In the specific embodiment illustrated in
(38) In alternate embodiments, it is envisioned that the specific configurations, dimensions, and/or positions of the guides 702.sub.A, 702.sub.B may be varied. For example, depending upon the type of transmission media 500 (e.g., FPC, coaxial cable, and/or wiring), as well as the brand, model, thickness, and/or intended use of the transmission media 500, the size and/or curvature of the guides 702.sub.A, 702.sub.B may be varied to adjust the bend radius realized by the transmission media 500 during relative rotation between the housings 300, 700.
(39) With reference now to
(40) The gimbal assembly 800 includes a motor assembly 900 having a hollow motor shaft 906 (
(41) To further support the transmission media 500, the housing 1000 may include a retainer 1100 (
(42) During use of the gimbal assembly 800, relative rotation between the upper housing 1000 and the lower housing (not shown) causes corresponding rotational displacement of the transmission media 500 within the housing 1000 via engagement with the retainer 1100. As the transmission media 500 is displaced within the housing 1000, the transmission media 500 is allowed to rotate within the internal passage 908 (
(43)
(44) The gimbal assembly 1200 includes a second (upper) housing 1300 with a clip 1302 and a clip mount 1304 that extends upwardly from a floor 1306 of the housing 1300. The clip 1302 is engageable with the clip mount 1304, and is configured and dimensioned to support the transmission media 500, which is shown as including both the aforementioned FPC 502 and wiring 504 in the illustrated embodiment. The clip 1302 may be formed from any suitable material, such as, for example, plastics, polymers, or the like. In alternate embodiments, it is envisioned that the housing 1300, the clip 1302, and/or the clip mount 1304 may be integrally formed, via injection molding, for example, or that the housing 1300, the clip 1302, and/or the clip mount 1304 may be formed as separate, discrete components. In the embodiment illustrated in
(45) The clip 1302 is generally cordiform in configuration, and includes respective inner and outer walls 1308, 1310 (
(46) The clip 1302 includes an extension 1312 that projects inwardly into an interior region of the clip 1302 so as to define a pair of opposing lobes 1314, 1316 (
(47) In certain embodiments, such as that illustrated in
(48) In some embodiments of the disclosure, it is envisioned that the clip 1302 may be devoid of the guide 1320. In such embodiments, it is envisioned that the transmission media 500, for example, the wiring 504, may simply extend into the housing 1300 through one of the lobes 1314, 1316 (
(49) During use of the gimbal assembly 1200, the wiring 504 is displaced within the housing 1300 via engagement with the retainer 1100, as discussed above in connection with the gimbal assembly 800, and the FPC 502 coils and uncoils about the clip 1302. More specifically, rotation of the housing 1300 in one direction, for example, clockwise, will result in coiling of the FPC 502 about the clip 1302, and rotation of the housing 1300 in the opposite direction, for example, counterclockwise, will result in uncoiling of the FPC 502 (or loosening of the coil). Incorporation of the clip 1302 thus allows for a reduction in the length of the wiring 504 by eliminating coiling thereof, and an increase in the length of the FPC 502 facilitated by coiling about the clip 1302.
(50) The combined routing facilitated by the gimbal assembly 1200 may provide advantages in certain applications. For example, by eliminating coiling in the wiring 504, and thereby reducing the length of the wiring 504, the integrity of the signal carried by the wiring 504 may be increased. Conversely, the increased length of the FPC 502 facilitated by coiling about the clip 1302 may allow for improvements not only in power distribution, but in transmission of digital data and/or control signals to the gimbal assembly 1200.
(51) With reference now to
(52) To maintain the coiled configuration of the FPCs 502, it is envisioned that each of the gimbal assemblies 1400 may include a hub (not shown) or other such structure to support the coiled configuration of the FPCs 502. For example, in certain embodiments, it is envisioned that the one or more of the gimbal assemblies 1400 may include the clip 1302 (
