Description

Technical Field

[0001] This invention relates to the field of mobile phone charging accessories technology, and in particular to a mobile phone charging interface conversion device. Background Technology

[0002] Mobile phones are typically charged by plugging a charging cable into the phone's charging port. Most current mobile phone charging ports are fixed at the bottom of the phone, and once the charging cable is inserted, its position remains fixed.

[0003] In scenarios such as holding the phone horizontally, playing games, watching videos, or using a stand, a fixed charging cable can easily interfere with the hand, desktop, or stand, and cause the charging cable to bend or be stressed near the interface, affecting the convenience of using the phone and the stability of the charging connection.

[0004] Existing right-angle charging cables or swivel charging adapters can usually only change the direction in which the charging cable extends near the original charging interface, but cannot move the connection position of the charging cable along the circumference of the phone. Therefore, when the phone is held in a different direction or placed in a different position, problems such as cable obstruction, bending, or interference can still easily occur. Summary of the Invention

[0005] This invention provides a mobile phone charging interface conversion device, capable of adjusting the connection position of the external charging cable along the circumference of the mobile phone while maintaining the charging connection during the adjustment process. The technical solution is as follows: The mobile phone charging interface conversion device provided by the present invention includes a closed-loop support body, a sliding female seat, a plug-in male head, a flexible ribbon cable, and a limiting component. The outer ring surface of the closed-loop support body is provided with a circumferential sliding groove extending along its circumference, and an annular conductive mounting groove is provided inside the closed-loop support body. An electrical connection slot is provided between the circumferential sliding groove and the annular conductive mounting groove.

[0006] An annular conductive mounting groove has an annular conductive track on each of its two opposite sidewalls. The two annular conductive tracks are insulated from each other, and each annular conductive track is provided with an elastic conductive contact piece that is electrically connected to it.

[0007] The sliding female seat is at least partially accommodated within a circumferential sliding groove. The sliding female seat is provided with a conductive connection portion that passes through an electrical connection slot and extends into an annular conductive mounting groove. The conductive connection portion is provided with two mutually insulated conductive terminals, each of which makes elastic contact with a corresponding elastic conductive contact piece.

[0008] The flexible cable has two insulated conductive lines inside. One end of each conductive line is electrically connected to two annular conductive tracks, and the other end is electrically connected to the corresponding conductive terminals inside the male connector. The limiting component is located on one side of the closed-loop support body and forms a clamping space for holding the mobile phone or mobile phone case.

[0009] In one embodiment of the present invention, guide limiting grooves are respectively formed on two opposite sidewalls of the circumferential sliding groove, and the two guide limiting grooves are respectively arranged along the extension direction of the circumferential sliding groove. Limiting sliding parts that slide and cooperate with the corresponding guide limiting grooves are respectively provided on both sides of the sliding female seat, and the two limiting sliding parts are respectively placed in the corresponding guide limiting grooves.

[0010] In one implementation of the present invention, the electrical connection slot is provided along the extension direction of the annular conductive mounting groove and connects the circumferential sliding groove and the annular conductive mounting groove. The groove width of the electrical connection slot is smaller than the groove width of the circumferential sliding groove and the annular conductive mounting groove, respectively.

[0011] In one implementation of the present invention, two sets of elastic conductive contacts are provided, each set corresponding to one of two annular conductive tracks. Each set of elastic conductive contacts includes multiple elastic sheet bodies spaced apart along the extension direction of the corresponding annular conductive track, and the two sets of elastic conductive contacts are arranged opposite to each other.

[0012] In one implementation of the present invention, the elastic sheet is a bent elastic sheet structure or an arc-shaped elastic sheet structure, and the elastic sheet protrudes toward the center of the annular conductive mounting groove.

[0013] In one embodiment of the present invention, two protruding fixing seats and two supporting seats are provided on one side of the closed-loop support body. The two supporting seats are respectively fixedly connected to the corresponding protruding fixing seats, and the protruding fixing seats are located between the supporting seats and the closed-loop support body. The opposite sides of the two supporting seats are respectively provided with grooves, and the two grooves together form a limiting channel for the sliding of the male connector, allowing the male connector to move along the limiting channel between the two protruding fixing seats.

[0014] In one embodiment of the present invention, the limiting component includes a support, a telescopic clamping seat, a telescopic guide rod, a movable clamping block, and a clamping spring. The support and the telescopic clamping seat are disposed on the same side of the closed-loop support body and are located at opposite ends of the closed-loop support body, respectively.

[0020] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Combination Figures 1 to 3 This embodiment provides a mobile phone charging interface conversion device, which includes a charging component and a limiting component. The charging component forms an electrical connection between the external charging cable and the mobile phone charging interface, and allows the connection position of the external charging cable to be adjusted along the circumference of the mobile phone; the limiting component clamps and fixes the conversion device to the mobile phone or mobile phone case.

[0022] The charging assembly includes a closed-loop support body 1, a guide limiting groove 5, a circumferential sliding groove 6, a sliding female seat 7, a raised fixing seat 8, a flexible ribbon cable 9, an annular conductive mounting groove 11, an elastic conductive contact piece 12, an annular conductive track 13, an electrical connection slot 14, a plug male connector 15, and a groove 16.

[0023] The closed-loop support body 1 has a closed-loop structure. In this embodiment, the closed-loop support body 1 is a rounded rectangular ring structure, and the four corners of the closed-loop support body 1 are rounded transition structures, so that the outer contour of the closed-loop support body 1 matches the circumferential contour of the mobile phone. The closed-loop support body 1 can also be a circular ring structure or an elliptical ring structure.

[0024] A circumferential sliding groove 6 is formed on the outer ring surface of the closed-loop support body 1. The circumferential sliding groove 6 extends circumferentially along the closed-loop support body 1 and forms an annular sliding path that matches the outer contour of the closed-loop support body 1. The sliding female seat 7 is at least partially accommodated within the circumferential sliding groove 6 and can move along the circumferential sliding groove 6. The charging connector of the external charging cable is inserted into the sliding female seat 7, so the change in position of the sliding female seat 7 can cause the connection position of the external charging cable to change circumferentially along the mobile phone.

[0025] The closed-loop support body 1 has guide and limiting grooves 5 on two opposite side walls of the circumferential sliding groove 6. The guide and limiting grooves 5 are arranged along the extension direction of the circumferential sliding groove 6 and form an annular limiting path that cooperates with the circumferential sliding groove 6. Limiting sliding parts that cooperate with the corresponding guide and limiting grooves 5 are respectively provided on both sides of the sliding mother seat 7. The limiting sliding parts are inserted into the corresponding guide and limiting grooves 5. When the sliding mother seat 7 moves, the limiting sliding parts move synchronously along the guide and limiting grooves 5. The guide and limiting grooves 5 guide the movement direction of the sliding mother seat 7 and prevent the sliding mother seat 7 from disengaging from the circumferential sliding groove 6.

[0026] The closed-loop support body 1 has an annular conductive mounting groove 11 and an electrical connection slot 14 inside. The annular conductive mounting groove 11 extends circumferentially along the closed-loop support body 1 and forms an annular conductive mounting space that matches the outer contour of the closed-loop support body 1. The electrical connection slot 14 is provided along the extending direction of the annular conductive mounting groove 11, and the electrical connection slot 14 connects the circumferential sliding groove 6 and the annular conductive mounting groove 11, forming an annular connecting channel between the circumferential sliding groove 6 and the annular conductive mounting groove 11.

[0027] The width of the electrical connection slot 14 is smaller than the width of the circumferential sliding groove 6 and the annular conductive mounting groove 11. The sliding female seat 7 is provided with a conductive connection part, which passes through the electrical connection slot 14 and extends into the annular conductive mounting groove 11. When the sliding female seat 7 moves along the circumferential sliding groove 6, the conductive connection part moves synchronously along the electrical connection slot 14 and remains extended into the annular conductive mounting groove 11.

[0028] An annular conductive track 13 is fixedly installed on each of the two opposite side walls of the annular conductive mounting groove 11. The two annular conductive tracks 13 are respectively arranged along the extension direction of the annular conductive mounting groove 11 and form two independent annular conductive paths. The two annular conductive tracks 13 are insulated from each other.

[0029] Two sets of elastic conductive contacts 12 are provided, each set being disposed on a corresponding annular conductive track 13 and electrically connected to the corresponding annular conductive track 13. Each set of elastic conductive contacts 12 includes multiple elastic sheets spaced apart along the extension direction of the corresponding annular conductive track 13, and the two sets of elastic conductive contacts 12 are arranged opposite to each other. In this embodiment, the elastic sheet is an arc-shaped spring structure protruding towards the center of the annular conductive mounting groove 11; the elastic sheet can also be a bent spring structure.

[0030] The sliding female seat 7 has two mutually insulated conductive terminals, both of which are located on the conductive connection portion. After the conductive connection portion passes through the electrical connection slot 14 and extends into the annular conductive mounting groove 11, the two conductive terminals respectively make elastic contact with a corresponding set of elastic conductive contacts 12. When the sliding female seat 7 moves along the circumferential sliding groove 6, the two conductive terminals maintain elastic contact with the corresponding elastic conductive contacts 12, so that when the sliding female seat 7 moves to different positions in the circumferential sliding groove 6, it still maintains electrical connection with the two annular conductive tracks 13.

[0031] The flexible ribbon cable 9 contains two mutually insulated conductive lines. One end of each conductive line is electrically connected to one of the two annular conductive tracks 13, and the other end is electrically connected to the corresponding conductive terminals inside the male connector 15. The flexible ribbon cable 9 can bend as the position of the male connector 15 changes to adapt to different thicknesses of mobile phones or mobile phone cases.

[0032] Two protruding fixing seats 8 are fixedly installed on one side of the closed-loop support body 1, with a gap between the two protruding fixing seats 8. Two support seats 10 are respectively fixedly connected to the corresponding protruding fixing seats 8, and the protruding fixing seats 8 are disposed between the support seats 10 and the closed-loop support body 1. The protruding fixing seats 8 can be fixed to the closed-loop support body 1 by adhesive, snap-fit ​​or embedding.

[0033] The two support seats 10 each have a groove 16 on their opposite sides. The two grooves 16 are arranged opposite each other and together form a limiting channel for the male connector 15 to slide. The male connector 15 can move along the limiting channel and is held and limited by two protruding fixing seats 8. When not in use, the male connector 15 is locked between the two protruding fixing seats 8. The grooves 16 and the protruding fixing seats 8 together restrict the position of the male connector 15, thereby reducing the possibility of the male connector 15 being squeezed, bumped, bent or intruded by foreign objects due to exposure.

[0034] The limiting assembly includes a support seat 10, a telescopic clamping seat 2, a telescopic guide rod 3, a movable clamping block 4, and a clamping spring 17. The two support seats 10 and the telescopic clamping seat 2 are located on the same side of the closed-loop support body 1, and the telescopic clamping seat 2 and the support seats 10 are respectively located at opposite ends of the closed-loop support body 1.

[0035] The telescopic clamping base 2 has multiple placement slots. One end of the telescopic guide rod 3 can be telescopically inserted into the corresponding placement slot and can extend and retract along the depth direction of the placement slot. The other end of the telescopic guide rod 3 is fixedly connected to the movable clamping block 4. The clamping spring 17 is disposed inside the telescopic guide rod 3. One end of the clamping spring 17 is fixedly connected to the telescopic clamping base 2, and the other end is fixedly connected to the movable clamping block 4.

[0036] When the movable clamping block 4 is pulled away from the support 10, the movable clamping block 4 causes the telescopic guide rod 3 to extend outward along the corresponding placement groove, and causes the clamping spring 17 to undergo elastic deformation, thereby increasing the distance between the movable clamping block 4 and the support 10, forming a clamping space to accommodate the mobile phone or a mobile phone with a protective case. After the movable clamping block 4 is released, the clamping spring 17, under the action of elastic restoring force, causes the movable clamping block 4 to move towards the support 10, clamping and fixing the mobile phone between the movable clamping block 4 and the support 10.

[0037] In use, first move the male connector 15 along the groove 16 to disengage it from the two protruding fixing seats 8 and remove it from the limiting channel. Then pull the movable clamping block 4 away from the support seat 10 to place the mobile phone into the clamping space between the movable clamping block 4 and the support seat 10. Then release the movable clamping block 4 to allow the limiting component to clamp and fix the mobile phone.

[0038] After the phone is clamped and fixed, adjust the male connector 15 to the position corresponding to the phone's charging interface, and then insert the male connector 15 into the phone's charging interface. After inserting the charging connector of the external charging cable into the sliding female connector 7, the external power is transmitted to the phone's charging interface through the conductive terminals, elastic conductive contact 12, annular conductive track 13, flexible ribbon cable 9 and male connector 15 in the sliding female connector 7, thereby charging the phone.

[0039] When the current position of the external charging cable affects the horizontal holding, operation, or stand placement of the phone, the sliding female base 7 is pushed to move along the circumferential sliding groove 6 on the outer ring surface of the closed-loop support body 1. The limiting sliding parts on both sides of the sliding female base 7 move along the guide limiting groove 5, and the conductive connection part moves synchronously along the electrical connection slot 14. The two conductive terminals respectively maintain elastic contact with the corresponding set of elastic conductive contacts 12. Thus, after the sliding female base 7 moves to different positions in the circumferential sliding groove 6, it still maintains electrical connection with the phone charging interface through the two annular conductive tracks 13, the flexible ribbon cable 9, and the plug male connector 15, so that the external charging cable can continuously supply power to the phone.

[0040] After charging is complete, unplug the external charging cable from the sliding female connector 7, and then unplug the male connector 15 from the phone charging port. Pull the movable clamping block 4 away from the support 10 to remove the phone from the clamping space, and release the movable clamping block 4 to reset it. Finally, place the male connector 15 into the limiting channel formed by the two grooves 16, and move it along the limiting channel between the two protruding fixing seats 8 to complete the storage of the male connector 15.

Terms such as “first” and “second” are used only to distinguish different components and do not indicate order, quantity, or importance.
