[0031] This embodiment provides a battery pack adapter for connecting a battery pack to charge the battery pack or use the electric energy of the battery pack to charge an external electrical device. Figure 1Schematic perspective view of the battery pack adapter provided by the embodiment of the present utility model Figure 2 Another perspective schematic perspective view of the battery pack adapter provided by the embodiment of the present utility model Figure 3 Schematic top view of the battery pack adapter provided by the embodiment of the present utility model. Please refer to Figure 1 、 Figure 2 and Figure 3 ,The battery pack adapter includes a housing 10, a battery pack interface 20, and a plug interface 30.

[0032] Both the battery pack interface 20 and the plug interface 30 are provided on the housing 10. The battery pack interface 20 is located on the outer surface of the housing 10, and the plug interface 30 is provided inside the housing 10. The battery pack interface 20 is used for detachably plugging with a battery pack (not shown), and the plug interface 30 is used for plugging with an external connector. In one implementation scenario, the other end of the external connector is connected to a power source, and the power source charges the battery pack through the adapter. In another implementation scenario, the other end of the external connector is connected to an electrical device, and the battery pack charges the external electrical device through the adapter. The external electrical device can be a mobile device such as a mobile phone, a tablet computer, or a smartwatch.

[0033] The battery pack interface 20 includes an electrode seat 21 and an opening 22 provided opposite to the electrode seat 21. The opening 22 is used for the battery pack to pass through to plug with the electrode seat 21. Specifically, the opening 22 is an open port formed on one side of the housing 10, and the battery pack plugs with the electrode seat 21 along the direction from the opening 22 to the electrode seat 21.

[0034] For the purpose of easy explanation, one side of the housing 10 where the battery pack interface 20 is located is taken as the bottom surface, the direction perpendicular to the bottom surface of the housing 10 is the height direction of the housing 10, the direction in which the battery pack interface 20 is adapted to insert the battery pack is the length direction of the housing 10, and the direction perpendicular to the length and height directions is the width direction. The dimension of the housing 10 in the length direction is greater than the dimension in the width direction.

[0035] In this embodiment, the battery pack interface 20 attaches the battery pack in a sliding manner. Specifically, the battery pack interface 20 includes two parallel sliding rails that extend along the length direction of the housing 10. Correspondingly, two matching sliding grooves are provided on the battery pack, and the lengths of the sliding grooves are approximately the same as those of the sliding rails. Align the two sliding rails with the sliding grooves on the battery pack and apply a thrust along the direction of the sliding rails, so that the battery pack can be inserted into the battery pack interface along the sliding rails and dock with the electrode seat, realizing the sliding plugging of the battery pack and the adapter.

[0036] The insertion interface 30 is plugged and unplugged with an external connector. Specifically, the insertion interface 30 is a conductive interface. The housing 10 is provided with an opening 110 facing the insertion interface 30, and the external connector passes through the opening 110 to be plugged with the insertion interface 30. The insertion interface 30 is electrically connected to an external electrical device or power source through the external connector. In this embodiment, the insertion interface 30 is a USB interface, and the corresponding external interface is a USB connector docked with the USB interface. The insertion interface 30 can also be other forms of interfaces, such as a Type-C interface. The present utility model does not limit the type of the insertion interface 30.

[0037] The housing 10 has opposite ends along its length direction, and the open end 22 and the opening 110 are oppositely arranged at both ends of the battery pack adapter in the length direction of the housing 10. With such a setting, when the battery pack and the external connector are inserted, the operator's palm can grasp both sides of the relatively narrow width of the housing, which is convenient for applying force, and sufficient operating space can be left at both ends of the length of the housing 10, which is convenient for the insertion operation of the battery pack and the external connector.

[0038] The housing 10 is also provided with a status display area 40 for displaying the charging and / or discharging status of the battery pack adapter. The status display area 40 is arranged between the open end 22 and the opening 110 in the length direction of the housing 10. During or after the operation of the battery pack interface 20 and the insertion interface 30, the status display area 40 can be seen at any time, which is convenient for timely understanding the working status of the battery pack adapter and does not additionally increase the volume of the housing 10. Specifically, the status display area can be used to display status parameters such as the charging or discharging current magnitude and power magnitude of the battery pack adapter.

[0039] The battery pack adapter provided in this embodiment has the open end for inserting the battery pack and the opening for inserting the external connector oppositely arranged at both ends of the battery pack adapter, and the status display area is arranged between the open end and the opening in the length direction of the housing, making the battery pack adapter have a compact structure, the plugging operation of the battery pack and the external connector more convenient, and at the same time it is more convenient to timely know the working status of the battery pack adapter.

[0040] Figure 3 Fig. shows a top view structural schematic diagram of the battery pack adapter with the side where the battery pack interface is located as the bottom surface. In Figure 3 In the illustrated embodiment, the battery pack adapter further includes a dust-proof member 60 for covering the opening 110. The dust-proof member 60 is movably arranged on the housing 10 and has an open state exposing the opening 110 and a closed state closing the opening 110 relative to the housing 10. The dust-proof member 60 can be operably switched between the open state and the closed state. When the dust-proof member 60 is in the open state, the opening 110 is exposed, and the external connector can be plugged with the insertion interface 30 through the opening 110.

[0041] Please continue to refer to Figure 3As shown, from the top view, the battery pack is plugged into the battery pack interface 20 along direction A, and the external connector is plugged into the plug interface 30 along direction B. The insertion direction A of the battery pack interface 20 for inserting the battery pack is opposite to the insertion direction B of the plug interface 30 for inserting the external connector. In this way, the battery pack and the external connector are plugged in from both ends of the housing in opposite directions, which makes the operation more convenient and there is no possibility of interference.

[0042] In one embodiment, please combine Figure 4 As shown, the opening 110 and the opening 22 are staggered in the height direction of the shell 10. In other words, the opening 110 and the opening 22 are not arranged directly opposite each other. On the one hand, the staggered arrangement can make the opening 110 avoid the electrode holder 21 that is directly opposite the opening 22, so that the opening 110 and the plug-in port 30 do not interfere with the electrode holder 21, thereby ensuring the compact and reasonable structural layout of the battery pack adapter. On the other hand, the side walls of the shell 10 and the opening 22 that are in the same height direction are not provided with a connection interface function, so that the operator can use the palm of his hand or other body parts to press against the above-mentioned side walls of the shell when plugging in the battery pack, making the insertion of the battery pack more convenient.

[0043] In order to facilitate the display of the value or change of the status parameter of the battery pack adapter, in the specific embodiment, please refer to Figure 3 The status display area 40 includes a plurality of display windows 41, and the plurality of display windows 41 are arranged in sequence along the length direction of the shell. Each display window 41 can be used to represent a certain amount of battery pack status parameters. The more display windows 41 are lit, the larger the corresponding battery pack status parameter value is. Exemplarily, the status parameter is to display the charging and / or discharging power of the battery pack adapter. Taking the battery pack charging as the scenario, the display windows 41 are lit from one side. The greater the charging power, the more display windows 41 are lit continuously, until all display windows 41 are lit, indicating that the battery pack is charged at full power. The display of the battery pack charging and / or discharging parameters makes it easy for the user to understand the charging status, so as to accurately predict the completion time of charging and discharging.

[0044] The battery pack adapter also includes a circuit board 50 housed in the housing 10, which is used to control the charging and / or discharging of the battery pack adapter. The circuit board 50 includes a substrate 51 and components disposed on the upper surface of the substrate. In order to reduce the adverse effect of the circuit board 50 on the increase in the overall volume of the housing and ensure that the battery pack adapter is compact and small, in one embodiment, see Figure 3 and Figure 4 The housing 10 includes a main body 11 and a protrusion 12 connected to the main body 11. The battery pack interface 20 is disposed on the main body 11, and the side of the main body where the battery pack interface 20 is located is the bottom surface of the main body 11, and the other side opposite to the battery pack interface 20 is the top wall 112 of the main body 11. The protrusion 12 is protruding from the top wall 112 of the main body 11.

[0045] A main accommodation space 115 is formed inside the main body portion 11, and an upper accommodation space 120 communicating with the main accommodation space 115 is formed inside the protruding portion 12. The substrate 51 is disposed in the main accommodation space, and the component (53) of the component that is higher than the top wall 112 protrudes from the main accommodation space 115 into the upper accommodation space 120. In this way, the housing is provided with a protruding portion for higher components. The protruding portion protrudes from the middle of the top wall, and the height of the main body portion can be kept small, only adding a locally high protruding portion. The overall structure of the adapter is small and compact, which is convenient for storage.

[0046] In a specific implementation, the protruding portion 12 is disposed in the middle region of the top wall 112. The top wall 112 surrounds the protruding portion 12, and the components 53 higher than the top wall 112 are centrally arranged in the middle region of the substrate 51, so that the height of the circuit board 50 is lower on the periphery and higher in the central region. Centrally arranging the higher components can reduce the volume of the protruding portion, thereby suppressing the increase in the overall volume of the adapter.

[0047] Specifically, please refer to Figure 1 and Figure 3 . The length direction of the protruding portion 12 is the same as the length direction of the housing 10, and the width direction of the protruding portion 12 is the same as the width direction of the housing 10. The protruding portion 12 is located in the middle region of the top wall 112. That is to say, the width of the protruding portion 12 is smaller than the width of the top wall 112, and the length of the protruding portion 12 is smaller than the length of the top wall 112. The top wall 112 is arranged to surround the protruding portion 12. The status display area 40 is disposed on the top wall 112 and is located on one side in the width direction of the protruding portion 12. Setting the status display area 40 at the top wall 112 on one side in the width direction of the protruding portion 12 is convenient for the status display area 40 to be arranged along the length direction of the housing 10. At the same time, the status display area 40 is located at the edge of the top wall 112 and is close to the side wall of the housing 10, which is convenient for observation.

[0048] In order to suppress the increase in the overall size of the battery pack adapter. In a specific implementation, please refer to Figure 2 and Figure 4 . The battery pack interface 20 includes two slide rails 24 for guiding the battery pack. The two slide rails 24 are located at the bottom side of the main accommodation space 115 and are arranged parallel to the plane where the substrate 51 is located. With such an arrangement, the slide rails for slidingly plugging the battery pack and the substrate are arranged in parallel, which can suppress the size in the height direction of the housing and ensure the overall size of the machine is compact.

[0049] Please refer to Figure 4, in the longitudinal direction of the housing 10, the insertion interface 30 is disposed in the main receiving space 115 and connected to the circuit board 50. The insertion interface 30 is located at the end side of the main receiving space 115, close to the opening 110 of the housing 10, facilitating exposure from the opening 110 and plugging with an external connector. Specifically, the end of the substrate 51 extends to the proximal side of the inner surface of the opening 110. The end of the substrate 51 abuts against the inner surface of the opening 110 or there is a very small gap therebetween. The insertion interface 30 is disposed on the upper surface of the substrate 51, opposite to the opening 110, and at least partially extends into the opening 110. The extension of the substrate to the proximal side of the opening facilitates the close arrangement of the insertion interface to the opening. The partial extension of the insertion interface into the opening facilitates the positioning of the insertion interface and reliable plugging with an external connector.

[0050] For facilitating the structural assembly and manufacturing of the housing, in a specific embodiment, please refer to Figure 4 and Figure 5 , an installation opening 114 is provided on the top wall 112 of the main body portion 11. The housing 10 further includes an upper cover which is disposed at the installation opening 114 and protrudes upward from the installation opening 114 to form a protruding portion 12. The advantage of such a setting is that the protruding portion is independently provided with the main body portion in the form of an upper cover, which can facilitate the adjustment of the shape of the protruding portion according to the shape of the protruding components. The main body portion can remain unchanged, improving the flexibility of housing modification and facilitating the molding and manufacturing of the protruding portion.

[0051] Specifically, the main body portion 11 includes a first half-shell 111 and a second half-shell 113. The first half-shell 111 and the second half-shell 113 are joined along the width direction of the housing. The installation opening 114 is formed at the joining seam of the first half-shell 111 and the second half-shell 113. The upper cover is located between the first half-shell 111 and the second half-shell 113 and is positioned by the joining of the first half-shell 111 and the second half-shell 113. Specifically, the structures of the first half-shell 111 and the second half-shell 113 are substantially the same and are approximately symmetric about the joining surface. Notches are provided at the joining seams of the first half-shell 111 and the second half-shell 113. After the two half-shells are joined, the two notches are joined to form a circumferentially closed installation opening 114, and the upper cover is clamped and positioned between the side walls of the installation opening 114. The main body portion is designed with a half-shell structure, and the upper cover is clamped and positioned at the joining seam of the two half-shells. The fixing of the upper cover can be achieved after the two half-shells are fixed, which is convenient for assembly and molding.

[0052] Obviously, the above-described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, those of ordinary skill in the art can make other different forms of changes or modifications without creative efforts, which should all fall within the protection scope of the present invention.
