[0028] It should also be noted that the division of multiple embodiments in the present invention is only for the convenience of description and should not constitute a special limitation. The features in various embodiments can be combined and referenced to each other without contradiction.

[0029] Reference Figure 1 and Figure 2 The present invention provides a mobile power supply 100, including a housing 10, an operating unit 20, a connector 30 and a charging management component 40 (see Figure 3 ). The housing 10 has an inner cavity and a through hole 11 connected to the inner cavity. The charging management component 40 includes a battery 41 disposed in the inner cavity. The operating part 20 is movably connected to the housing 10. The connector 30 is electrically connected to the battery 41. The connector 30 is movably connected to the housing 10, and the connector 30 can be extended and retracted relative to the housing 10 as the operating part 20 moves. So as to extend or retract into the inner cavity through the through hole 11. Among them, the connector 30 is used to be plugged into the charging port of the device to be charged. The charging management component 40 is used to provide power to the device to be charged through the connector 30.

[0030] Reference Figure 3 The housing 10 includes, for example, a front housing 12 and a rear housing 14 that are arranged opposite to each other, and a side housing 13 that is located between the front housing 12 and the rear housing 14. The front housing 12, the rear housing 14, and the side housing 13 together enclose an inner cavity. The operating unit 20 can refer to Figure 1 and Figure 3 The through hole 11 can be arranged on the side shell 13 or on other positions of the shell 10.

[0031] The operating part 20 may be a structure that can be operated by the user, such as a slide cover, a knob, a button, or a paddle. Accordingly, the user may operate the operating part 20 by sliding the slide cover, turning the knob, pressing a button, or turning the paddle.

[0032] The connector 30 can be determined according to the type of the charging port of the electronic device that needs to be matched, and can be a microUSB connector, a miniUSB connector, a type-C connector, a lighting connector, etc.

[0033] The operating part 20 can be directly connected to the joint 30 or indirectly fixedly connected to the joint 30 through a structure such as a moving platform 60. When the operating part 20 is operated, the joint 30 can move synchronously with the operating part 20. Alternatively, the operating part 20 can be connected to the joint 30 through a driving mechanism 50 that converts the movement direction or the movement distance. When the operating part 20 is operated, the driving mechanism 50 converts the movement of the operating part 20 and then drives the joint 30 to extend and retract.

[0034] Reference Figure 3 The charging management component 40 also includes a control circuit board 42, and the battery 41 stores electricity. When the connector 30 is plugged into the charging port of the device to be charged, the circuit on the control circuit board 42 transmits the electricity stored in the battery 41 to the device to be charged through the connector 30, so as to charge the device to be charged. The charging management component 40 also includes a charging interface, and the side shell 13 is also provided with a charging jack 15, so that an external power source can be connected to the charging interface through the charging jack 15 to charge the battery 41.

[0035] Figure 1 It is a schematic diagram of the overall structure of the mobile power supply 100 when the connector 30 extends out of the inner cavity. Figure 2 FIG. 1 is a schematic diagram of the overall structure of the mobile power supply 100 when the connector 30 is retracted into the inner cavity. Figure 1 , the connector 30 extends out of the inner cavity, and the connector 30 can be plugged into the charging port of the device to be charged to charge the device to be charged. When the charging function of the mobile power supply 100 is not needed after charging, the charging function of the mobile power supply 100 can be charged according to the Figure 1 The operating part 20 is slid downward in the direction shown, so that the joint 30 moves downward and is retracted into the inner cavity through the through hole 11, thereby achieving Figure 2 The connector 30 is protected by the housing 10 and is not easily damaged by knocks. Figure 2 Slide the operating part 20 upward in the direction shown so that the connector 30 extends out of the inner cavity to Figure 1 The mobile power supply 100 provided by the above embodiment of the utility model allows the user to operate the operating part 20 to achieve the extension and retraction of the connector 30, so that the connector 30 can be retracted into the inner cavity when the charging function is not needed, thereby preventing the connector 30 from being always exposed to the outside and being bumped or damaged.

[0036] In some embodiments, the operating part 20 is slidably connected to the housing 10, and the sliding direction of the operating part 20 is the same as or opposite to the extension direction of the joint 30. For example, if the operating part 20 is fixedly connected to the joint 30, then refer to Figure 1 and Figure 2 As shown, when the operating part 20 slides in a direction gradually away from the through hole 11 (downward), the joint 30 also moves downward and retracts into the inner cavity. When the operating part 20 slides in a direction gradually approaching the through hole 11 (upward), the joint 30 also moves upward and extends out of the inner cavity. Therefore, the movement direction of the operating part 20 can be the same as the extension and retraction direction of the joint 30.

[0037] Alternatively, in some embodiments, a driving mechanism 50 for changing direction may be provided between the operating portion 20 and the joint 30 so that the direction of the operation is changed. Figure 1 When the operating part 20 is slid in a direction gradually approaching the through hole 11 (upward), the joint 30 moves downward and retracts into the inner cavity. When the operating part 20 is slid in a direction gradually away from the through hole 11 (downward), the joint 30 moves upward and extends out of the inner cavity. The movement direction of the operating part 20 is opposite to the extension and retraction direction of the joint 30.

[0038] In some embodiments, the mobile power source 100 includes a driving mechanism 50 , which is connected between the operating portion 20 and the connector 30 . The operating portion 20 is located outside the inner cavity, and the driving mechanism 50 is located inside the inner cavity.

[0039] In some embodiments, the driving mechanism 50 includes a motion direction conversion mechanism, and the motion direction of the operating part 20 is different from the extension direction of the joint 30. For example, the motion direction conversion mechanism can be a circular motion to linear motion mechanism, and more specifically, it can be a gear rack mechanism, a worm gear mechanism, a cam mechanism, a screw nut mechanism, a crank slider mechanism, etc.

[0040] For example, in some embodiments, the operating part 20 may also be rotatably connected to the housing 10 , and the extension direction of the joint 30 may be axially along the rotation direction of the operating part 20 , or the extension direction of the joint 30 may be perpendicular to the rotation direction of the operating part 20 .

[0041] In some embodiments, the drive mechanism 50 includes a motion ratio conversion mechanism, and the motion stroke of the operating part 20 is different from the telescopic stroke of the joint 30. The motion ratio conversion mechanism can also be called a motion magnification / reduction mechanism. For example, the drive mechanism 50 designs the transmission ratio of the driving member 51 and the driven member 52 so that when the operating part 20 is operated slightly or moved a short distance, the joint 30 can be fully extended out of the inner cavity or fully retracted into the inner cavity, so that the space can be reasonably used and the operation is convenient. For example, the motion ratio can be converted by meshing two gears of different sizes (diameter, number of teeth, etc.) with each other.

[0042] In some embodiments, the driving mechanism 50 can be designed as a mechanism that can convert both the motion ratio and the motion direction, and a combination of the above-mentioned mechanisms can be used. That is, the driving mechanism 50 is a combination of any one or more of a gear rack mechanism, a crank slider mechanism, a cam mechanism, a screw nut mechanism, and a worm gear mechanism.

[0043] In some embodiments, the driving mechanism 50 includes a driving member 51 and a driven member 52, wherein the driving member 51 is connected to the operating portion 20. The driving member 51 can move relative to the housing 10 as the operating portion 20 is operated. The driven member 52 is connected to the joint 30 and to the driving member 51, and the driven member 52 can be driven by the driving member 51 to drive the joint 30 to extend and retract.

[0044] For example, refer to Figure 4 , Figure 5 and Figure 8 The number of the driving mechanisms 50 can be two, and the two driving mechanisms 50 are respectively arranged on opposite sides of the joint 30, which can drive the joint 30 to extend and retract more smoothly.

[0045] In some specific embodiments, the driving member 51 and the driven member 52 are both rack structures and are slidably connected to the housing 10. In some embodiments, the driving mechanism 50 further includes a transmission member 53, which is a gear structure and meshes with the driving member 51 and the driven member 52 respectively.

[0046] For example, refer to Figure 4 Taking the driving mechanism 50 on the left side of the joint 30 as an example, the transmission member 53 includes a gear meshing with the driving member 51 and the driven member 52 respectively. By setting this gear, the movement direction of the operating part 20 can be opposite to the extension direction of the joint 30. Figure 4 When the operating part 20 is slid upward (towards the direction gradually approaching the through hole 11), the operating part 20 drives the rack of the driving member 51 to slide upward, the gear of the transmission member 53 (on the left side of the connector 30) rotates clockwise, and the rack of the driven member 52 is driven to slide downward (towards the direction gradually away from the through hole 11), and the connector 30 is retracted into the inner cavity. Figure 4 When the operating part 20 is slid downward (in a direction gradually away from the through hole 11) in the direction of the drive mechanism 50, the operating part 20 drives the rack of the driving member 51 to slide downward, the gear of the transmission member 53 (on the left side of the joint 30) rotates counterclockwise, and the rack of the driven member 52 is driven to slide upward (in a direction gradually approaching the through hole 11), and the joint 30 extends out of the inner cavity. Therefore, the above-mentioned arrangement enables the driving mechanism 50 to achieve the conversion of the movement direction. And the specifications of the racks of the driving member 51 and the driven member 52 can be designed so that when the gear of the transmission member 53 rotates by the same angle, the distance required for the driving member 51 to slide is smaller than the distance required for the driven member 52 to slide, so that the driving mechanism 50 can achieve the conversion of the movement distance at the same time.

[0047] In some embodiments, reference Figure 5 and Figure 6 The transmission member 53 includes a first gear 531 and a second gear 532 meshing with each other. The first gear 531 meshes with the driving member 51, and the second gear 532 meshes with the driven member 52. The first gear 531 and the second gear 532 are arranged so that the movement direction of the operating part 20 is consistent with the extension direction of the joint 30. For example, referring to Figure 5 In the direction shown, the operating part 20 is slid downward (in the direction gradually away from the through hole 11) to drive the rack of the driving member 51 to slide downward, then the first gear 531 rotates counterclockwise, the second gear 532 rotates clockwise, the rack of the driven member 52 slides downward, and the connector 30 moves downward and retracts into the inner cavity, achieving Figure 6 The status shown. Figure 6 In the orientation shown, the operating part 20 is slid upward (in the direction gradually approaching the through hole 11), driving the rack of the driving member 51 to slide upward, the first gear 531 rotates clockwise, the second gear 532 rotates counterclockwise, the rack of the driven member 52 also slides upward, and the joint 30 moves upward and extends out of the inner cavity. The parameters such as the diameter or number of teeth of the first gear 531 and the second gear 532 can be designed to be different, so that when the first gear 531 and the second gear 532 rotate a certain angle, the moving distance of the driving member 51 is smaller than the moving distance of the driven member 52, so that the driving mechanism 50 can realize the conversion of the moving distance.

[0048] In some embodiments, reference Figure 7 , the driving member 51 may be, for example, a lead screw, and the driven member 52 may be, for example, a nut. The lead screw of the driving member 51 has an external thread, and the nut of the driven member 52 has an internal thread. The nut is sleeved on the lead screw of the driving member 51, and the internal thread is engaged with the external thread of the lead screw. The operating part 20 may be, for example, a dial, part of which is located outside the housing 10, and the other part passes through the through hole on the front housing 12 and extends into the inner cavity to be connected to one end of the driving member 51. The axial direction of the dial is consistent with the axial direction of the driving member 51. According to Figure 7 When the dial is turned to the right, the lead screw of the driving member 51 rotates accordingly, and the nut of the follower 52 slides downward, thereby driving the joint 30 to slide downward and retract into the inner cavity. Conversely, when the dial is turned to the left, the lead screw of the driving member 51 rotates accordingly, and the nut of the follower 52 slides upward, thereby driving the joint 30 to slide upward and extend out of the inner cavity. At this time, the movement direction of the operating part 20 is different from the extension direction of the joint 30. Specifically, the rotation plane of the operating part 20 is perpendicular to the extension direction of the joint 30. The diameter of the operating part 20 can be set to be smaller, and the extension and retraction of the joint 30 can be achieved by rotating the operating part 20 multiple times, thereby reducing the space required for operating the operating part 20.

[0049] In some embodiments, reference Figure 8 The driving member 51 may be a cam, and the driven member 52 may be a push rod. When the operating part 20 is operated, the driving member 51 is moved according to Figure 8 When the driven member 52 is rotated in the direction shown, it can reciprocate up and down, so the joint 30 can be extended and retracted. At this time, the movement direction of the operating part 20 is different from the extension direction of the joint 30. Specifically, the axis of the rotation direction of the operating part 20 is perpendicular to the extension direction of the joint 30. Similarly, by setting the driving member 51 as a cam, the space required for operating the operating part 20 can also be reduced.

[0050] In some embodiments, the housing 10 is provided with a first limiting structure 71, and the driving member 51 is connected to the housing 10 by sliding in a limiting manner through the first limiting structure 71. And / or the housing 10 is provided with a second limiting structure 72, and the driven member 52 is connected to the housing 10 by sliding in a limiting manner through the second limiting structure 72. Figure 5 The first limiting structure 71 is, for example, a through slot provided on the housing 10. The driving member 51 can not only pass through the through slot and be fixedly connected to the operating portion 20, but also limit the distance of the driving member 51 sliding up and down through the through slot, and can align the sliding direction of the driving member 51. Figure 5 The second limiting structure 72 is, for example, a limiting block, and a limiting groove 521 is provided on the follower 52. The follower 52 is connected with the limiting block through the limiting groove 521, and the sliding distance of the follower 52 can be limited and the sliding direction of the follower 52 can be aligned to ensure the extension and retraction of the joint 30. Of course, in some other embodiments, the first limiting structure 71 and the second limiting structure 72 can also adopt other limiting structures such as a slider and a slide groove, a sleeve and a limiting column, and this embodiment is not limited to the above examples.

[0051] In some embodiments, the charging management component 40 is fixed in the housing. The connector 30 is connected to the charging management component 40 via a flexible flat cable. The flexible flat cable connection ensures that the electrical connection between the connector 30 and the charging management component 40 remains stable after multiple operations, and occupies less space.

[0052] In other embodiments, the charging management component 40 is fixedly connected to the connector 30, and when the connector 30 moves relative to the housing 10, the charging management component 40 can move synchronously with the connector 30. When the connector 30 extends out of the inner cavity through the through hole 11, the charging management component 40 moves in a direction gradually approaching the through hole 11. When the connector 30 is retracted into the inner cavity through the through hole 11, the charging management component 40 moves in a direction gradually away from the through hole 11. By moving the charging management component 40 and the connector 30 together, a stable electrical connection between the charging management component 40 and the connector 30 can be ensured, thereby ensuring the service life.

[0053] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modifications to equivalent embodiments of equivalent changes using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
