For better appearance, the width of the receiving hole 107 in the vertical direction is set to be suitable for the size of the connector assembly 300 described in detail below. The first and

third bore segments

207, 407 each have a smaller bore width than the second bore segment 307. In another embodiment, the width of the receiving hole 107 may be uniform.

Referring to fig. 2, at least one connection hole 108 is formed on a side plate of the lower case 130 having the receiving hole 107, and the connection hole 108 is located near the receiving hole 107. A data interface 430 may be disposed within the housing 100 corresponding to the location of the connection hole 108. The user may establish a connection between the data interface 430 and an external electronic device through a data line. As will be further described below. The position of the connection hole 108 is adjusted according to the position of the data interface 430 in the housing 100. The number and shape of the connection holes 108 can be set according to actual needs.

In the present embodiment, three connection holes 108 are disposed near the receiving hole 107, and correspond to different types of data interfaces 430. As shown in fig. 2, a connecting hole 108 is provided below the receiving hole 107; the other two connection holes 108 are provided on the right side of the housing hole 107 and are arranged in order in the vertical direction.

Referring to fig. 4, a surface of the lower housing 130 facing the upper housing 110 is provided with a supporting column 157, and the supporting column 157 is used for supporting and fixing some components in the housing 100 by screws. The supporting column 157 has the same height as the second rotating part 153. The number and distribution of the supporting columns 157 are set according to actual needs, and the number of the supporting columns 157 is generally set to be at least 3 to increase the supporting stability.

Referring to fig. 4, a key hole 104 is formed on the front side plate 133 of the lower housing 130 for receiving a function key.

The battery cell 200 and the connector assembly 300 in the mobile power supply may be directly electrically connected, or may form an electrical connection through an intermediate element. Referring to fig. 5, in the present embodiment, the mobile power supply includes a PCB circuit board 400, and the battery cell 200 and the connector assembly 300 are electrically connected through the PCB circuit board 400. That is, the connector assembly 300 is electrically connected to the PCB circuit board 400, and the PCB circuit board 400 is electrically connected to the battery cell 200.

Referring to fig. 5, in a state that the PCB 400 is not disassembled from the portable power source, the PCB 400 is accommodated in the second accommodating area 102. As shown in fig. 8, in the assembled state of the mobile power supply, the connector assembly 300 and the PCB 400 are stacked in the thickness direction of the mobile power supply; compared with other arrangement modes, the internal occupied space of the mobile power supply can be reduced. The connector assembly 300 is closer to the upper housing 110 than the PCB circuit board 400, and the PCB circuit board 400 is supported on the supporting posts 157 (not shown in the drawings) provided on the lower housing 130 and fixed with respect to the supporting posts 157.

Referring to fig. 6 (a), the connector assembly 300 includes a patch circuit board 310, and at least two charging plugs 320 are disposed on the patch circuit board 310. Charging plug 320 is disposed in the circumferential direction of relay circuit board 310. Charging plug 320 is disposed on adapting circuit board 310 along the rotation direction of adapting circuit board 310. When the relay circuit board 310 rotates around the center line perpendicular to the thickness thereof, different charging plugs 320 may alternatively protrude out of the housing 100 through the receiving holes 107.

Referring to fig. 6 (a), in the present embodiment, the adapting circuit board 310 has a rectangular plate shape, and the adapting circuit board 310 includes four side surfaces that are sequentially and hermetically connected, namely, a front side surface, a rear side surface, a left side surface and a right side surface. Charging plug 320 is disposed perpendicular to the plane of the side of adapting circuit board 310. The plane defined by the length direction and the width direction of the charging plug 320 is located on the rotation plane of the connector assembly 300, so that the volume of the mobile power supply is not further increased in the case where a plurality of charging plugs 320 are provided.

The plane of rotation of the connector assembly 300 is perpendicular to the thickness direction of the connector assembly 300.

Referring to (a) of fig. 6, in the present embodiment, the charging plugs 320 are provided in three. One charging plug 320 is perpendicular to the plane of the front side, one charging plug 320 is perpendicular to the plane of the back side, and one charging plug 320 is perpendicular to the plane of the left side. The three charging plugs 320 are of type c usb type, micro usb type and lightning type, and can be connected with electronic devices of different interface types.

In another embodiment, the size of the mobile power supply and the type and number of required interfaces can be adjusted accordingly. For example, two charging plugs 320 spaced a set distance apart may be provided on one side of the relay circuit board 310, if the size allows and no interference occurs during use.

Referring to fig. 6 (a), the surface of the adapting circuit board 310 facing the PCB circuit board 400 is provided with an electrical connector 311, and the electrical connector 311 is used for electrically connecting the adapting circuit board 310 and the PCB circuit board 400.

The electrical connector 311 is an elastic electrical conductor. When the portable power source is in the assembled state, the electrical connector 311 is applied with a predetermined pressure, and generates a predetermined compression deformation. When the connector assembly 300 rotates relative to the housing 100, the connector assembly 300 may float up and down, and the electrical connector 311 has the characteristic of elastic deformation, so that the electrical connection relationship between the adapting circuit board 310 and the PCB 400 is stable, and the problem of poor contact between the stacked connector assembly 300 and the PCB 400 is avoided.

At least two electrical connectors 311 are provided to form positive and negative electrode loops. In this embodiment, four electrical connectors 311 are arranged in parallel to form two sets of positive and negative loops, and are arranged from a position close to the center of the adapting circuit board 310 to a direction away from the center of the adapting circuit board 310.

In other embodiments, multiple rows of electrical connectors 311 can be provided around a centerline perpendicular to the thickness of the patch circuit board 310 to further increase the stability of the conduction process.

The electrical connector 311 may employ a spring metal pin or other element having elastic conductivity.

Referring to fig. 6 (a), in the present embodiment, the connector assembly 300 further includes a base 330, and the base 330 is a plastic body injection molded structure that is embedded with the adaptor circuit board 310, the charging plug 320 and the electrical connector 311. The structure of the connector assembly 300 can be seen from fig. 6 (b) and 8, the adapting circuit board 310 is fixed in the base 330; the charging plug 320 partially protrudes and is perpendicular to the side of the base 330 to connect the electronic device, and a plane defined by the length direction and the width direction of the charging plug 320 is located on the rotation plane of the base 330; the electrical connector 311 partially protrudes from the upper surface of the base 330 to be electrically connected to the PCB 400.

Referring to (b) of fig. 6, a projection of the substrate 330 in the vertical direction is a square, and the substrate 330 has a rectangular parallelepiped structure, and the height in the vertical direction is smaller than the length and width thereof. Compared with other structures, such as a cube, the connector assembly 300 has a smaller footprint and is easier to connect to an electronic device within a predetermined rotation range.

The thickness of the substrate 330 is not larger than the aperture width of the second hole segment 307 of the receiving hole 107.

Referring to fig. 2, when the base 330 is assembled to the housing 100 and the mobile power supply is in a storage state (which may be simply referred to as a storage state), the base 330 corresponds to a position of the second hole segment 307 of the receiving hole 107 and is partially received in the second hole segment 307; the plane of the side of the base 330 away from the center of the housing 100 coincides with the plane of the opening of the receiving hole 107 away from the center of the housing 100. Two of the charging plugs 320 correspond to the first hole segment 207 and the third hole segment 407 of the receiving hole 107, and are partially received in the first hole segment 207 and the third hole segment 407. The opening of the receiving hole 107 away from the center of the housing 100 means that the receiving hole 107 is close to one end of the user when the charging plug 320 is connected to the electronic device.

Referring to fig. 2, the receiving hole 107 penetrates through the thickness of the side plate of the lower case 130. The plane of the front side of the base 330 approximately coincides with the plane of the sealing line that encloses the opening outside the receiving hole 107. To facilitate the user applying a force to the base 330 partially received in the second bore section 307 to rotate the connector assembly 300; when the portable power source is not used, the base 330 is not exposed out of the housing 100, so that the occupied space is reduced. The base 330 partially extends out of the housing 100 when rotated. The outer opening of the receiving hole 107 means that the receiving hole 107 is close to one end of the user when the charging plug 320 is connected to the electronic device.

In other embodiments, the base 330 may be a separate component, and may be connected to the pcb 310, the charging plug 320 and the electrical connector 311 by gluing or other means, so long as it can protect the pcb 310, the charging plug 320 and the electrical connector 311.

As shown in fig. 6 (b), two opposite surfaces of the base 330 perpendicular to the thickness of the relay circuit board 310 are provided with a first rotating shaft 331 and a second rotating shaft 332, respectively (see fig. 8). The center lines of the first and second rotation axes 331 and 332 are located on the same line. As shown in fig. 8, when the mobile power supply is in an assembled state, the first rotating shaft 331 is inserted into the first rotating portion 113 and can rotate relative to the first rotating portion 113, and the second rotating shaft 332 is inserted into the second rotating portion 153 and can rotate relative to the second rotating portion 153, so that the charging plugs 320 on the adaptor circuit board 310 can sequentially extend out of the housing 100. The charging plug 320 has a generally flat rectangular parallelepiped shape and a predetermined thickness. The size of the charging plug 320 in the up-down direction is defined as the thickness of the charging plug 320; the size of the charging plug 320 in the front-rear direction is defined as the width of the charging plug 320; the size of the charging plug 320 in the left-right direction is defined as the length of the charging plug 320, and the relative movement direction of the charging plug 320 and the electronic device at the time of connection is the length direction of the charging plug 320. In the present embodiment, the thickness direction of the charging plug 320 is parallel to the center line of the first rotating shaft 331 and the center line of the second rotating shaft 332.

The first and second

rotating shafts

331 and 332 may be integrally injection-molded with the base 330, or may be fixed to the base 330 by welding, bonding, or the like, independently of the base 330.

In other embodiments, the first and second

rotating shafts

331 and 332 may be selectively provided with one of them, that is, only the first rotating shaft 331 or only the second rotating shaft 332 is provided. Accordingly, changing the dimensions of the housing 100 and associated components or simply changing the structure can achieve the above-described rotation of the connector assembly 300 relative to the housing 100.

In other embodiments, the connector assembly 300 may not have the base 330, and the first rotating shaft 331 and/or the second rotating shaft 332 may be directly fixed on the adapting circuit board 310.

In order to prevent the connector assembly 300 from being rotated after the connector assembly 300 is rotated or in a received state, the first rotating shaft 331 and/or the second rotating shaft 332 may be provided with an elastic deformation characteristic. For example, when the connector assembly 300 is rotated, the first rotation shaft 331 is deformed, and a frictional force is generated between the first rotation shaft 331 and the first rotation part 113 within a predetermined range. When the connector assembly 300 stops rotating, the first rotation shaft 331 is deformed to form a tight fit with the first rotation part 113.

In another embodiment, a rubber damping ring or a rubber damping block with a predetermined size may be disposed on the surface of the first rotating shaft 331 and/or the second rotating shaft 332 to prevent the connector assembly 300 from rotating freely. And is not exhaustive herein.

The first rotation shaft 331 and the first rotation part 113 may be interchanged in shape, and the second rotation shaft 332 and the second rotation part 153 may be interchanged in structure. As long as the structure capable of realizing the mutual rotation effect is enough.

Referring to fig. 7, a central region of the PCB 400 is provided with a through hole 410 along a thickness direction of the PCB 400. Referring to fig. 8, in the assembled state of the portable power source, the connector assembly 300 is stacked on the PCB 400, and the through hole 410 faces the second rotating shaft 332 on the connector assembly 300. One end of the second rotating shaft 332 far from the relay circuit board 310 is received in the second rotating part 153 through the through hole 410.

Referring to fig. 7, the surface of the PCB 400 opposite to the connector assembly 300 is provided with a conductive portion 450. The conductive part 450 includes a conductive ring 420, and the conductive ring 420 is used to connect with the electrical connector 311, so that the adapting circuit board 310 is connected with the PCB circuit board 400, and further electrically connected with the battery cell 200 through the PCB circuit board 400. The center line of the conductive ring 420 coincides with the center line of the via 410.

The conductive ring 420 is configured to be circular according to the rotation trace of the connector assembly 300, so that the electrical connector 311 is electrically connected to the conductive ring 420 continuously during the rotation of the connector assembly 300.

In the present embodiment, the conductive rings 420 are provided in 4 ring-shaped structures spaced apart by a predetermined gap, corresponding to the arrangement of the electrical connectors 311. Referring to fig. 8, in the assembled state of the mobile power supply, the conductive rings 420 are connected to the electrical connectors 311 in a one-to-one correspondence manner.

In other embodiments, according to other rotation tracks of the connector assembly 300, for example, the rotation track of the connector assembly 300 is set to rotate clockwise by 0 ° to 180 ° or counterclockwise by 0 ° to 180 °, that is, the connector assembly 300 does not rotate 360 ° to sequentially extend different types of charging plugs 320 out of the housing 100; in this case, the conductive ring 420 may be formed in a semicircular ring shape or the like. The shape of the conductive ring 420 may be set according to the rotation trace of the connector assembly 300, that is, the projection shape of the conductive portion 450 may be an arc shape or a circular shape with a set width along the thickness direction of the PCB 400.

Referring to fig. 7, the PCB 400 is provided with a data interface 430. The position distribution of the data interfaces 430 on the PCB circuit board 400 corresponds to the position distribution of the connection holes 108 on the lower housing 130. The PCB circuit board 400 is supported on the supporting columns 157, a set distance is provided between the lower surface of the PCB circuit board 400 and the lower housing 130, and a data interface 430 may be disposed on a side of the PCB circuit board 400 facing the lower housing 130.

The connector assembly 300 and the PCB circuit board 400 are sequentially stacked in a direction from the upper case 110 to the lower case 130. The center line of the first rotation part 113 provided on the upper housing 110, the center line of the first rotation shaft 331 provided on the connector assembly 300, the center line of the second rotation shaft 332 provided on the connector assembly 300, the center line of the through hole 410 provided on the PCB panel 400, and the center line of the second rotation part 153 provided on the lower housing 130 are substantially positioned on the same straight line. One end of the first rotating shaft 331 away from the adapting circuit board 310 is accommodated in the first rotating part 113; one end of the second rotating shaft 332, which is far away from the relay circuit board 310, is received in the second rotating part 153 after passing through the through hole 410. The electrical connector 311 disposed on the connector assembly 300 is connected to the conductive ring 420 disposed on the PCB board 400. The PCB 400 is connected to the battery cell 200 via a flexible circuit board (not shown).

The mobile power supply is provided with the connector assembly 300 capable of rotating relative to the casing 100, the charging plugs 320 of different types are arranged on the connector assembly 300 along the rotating direction, and the corresponding charging plugs 320 can extend out of the casing 100 to charge the electronic device by rotating the connector assembly 300, so that the operation is simple and convenient. The electronic equipment can be charged under the condition that no data line exists, and the electronic equipment with different interface types can be met. The adapter or the all-in-one data line and the like are not needed, and the carrying is convenient.

When it is not necessary to charge the external electronic device using the data line, the edge position of the base 330 fitted on the relay circuit board 310 may be pushed by hand. The charging plug 320 integrally formed with the base 330 is rotated by a corresponding angle such that the charging plug 320 at least partially protrudes out of the housing 100. When a force is applied to the extended charging plug 320 to rotate to a predetermined position, referring to fig. 9, the connector assembly 300 is in a use state, and at this time, the charging plug 320 extends out of the housing 100 and can be connected to an external electronic device. The electronic equipment can be charged by opening the switch key.

When another type of charging plug 320 is desired, the connector assembly 300 may continue to be rotated until the desired connector assembly 300 extends out of the housing 100.

When the portable power source is in the storage state, the charging plug 320 is accommodated in the accommodating hole 107 and the housing 100, so as to reduce the external occupied space, as shown in fig. 1.

When the portable power source needs to be charged, the data interface 430 on the PCB circuit board 400, such as a micro usb type female socket, can be connected with an electronic product or a charging plug through connecting an external data line.

When the electronic device needs to be charged in a wired manner, the data interface 430 on the PCB circuit board 400, such as a USB-a type female socket or a type-c USB type female socket, is connected to the electronic product through a data line.
