[0029] Embodiment 1

[0030] This embodiment provides a battery pack adapter (which can also be simply referred to as an adapter) for connecting a battery pack to charge the battery pack or use the electrical energy of the battery pack to charge an external electrical device. Figure 1 is the three-dimensional structural schematic diagram of the battery pack adapter provided by the embodiment of the present invention, Figure 2 As Figure 1 shown in the partial exploded structural schematic diagram of the battery pack adapter. Please refer to Figure 1 and Figure 2 , the battery pack adapter includes a main body 10, an upper cover 20 and a circuit board 30.

[0031] Among them, a battery pack interface is provided on the main body 10, on the outer surface of the main body 10, and the battery pack interface is used for detachably plugging with a battery pack (not shown). Specifically, please combine Figure 3As shown, the battery pack interface includes an electrode seat 40 and an opening 18 provided opposite to the electrode seat 40. The opening 18 is an open port formed on one side of the main body 10, and the opening 18 is used for the battery pack to pass through so as to be plugged into the electrode seat 40. In a specific implementation, the battery pack is plugged into the electrode seat 40 along the direction from the opening 18 to the electrode seat 40.

[0032] For the purpose of easy illustration, one side surface of the main body 10 where the battery pack interface is located is defined as the bottom surface of the main body 10, and the side opposite to the battery pack interface is the top wall 13 of the main body 10. The direction perpendicular to the bottom surface of the main body 10 is the height direction of the main body 10, and the direction in which the battery pack interface is adapted to be inserted into the battery pack (such as Figure 5 the direction A shown) is the length direction of the housing 10, and the direction perpendicular to the length and height directions is the width direction. In this embodiment, the dimension of the main body 10 in the length direction is greater than the dimension in the width direction. Based on the above definitions, the upper cover 20 is located above the main body 10, and the battery pack interface is located on the bottom side of the main body 10.

[0033] In this embodiment, the length direction of the upper cover 20 is the same as the length direction of the main body 10, and the width direction of the upper cover 20 is the same as the width direction of the main body 10. The size of the upper cover 20 is adapted to that of the main body 10, making the overall appearance more beautiful and coordinated.

[0034] A main cavity 14 is formed in the main body 10. The battery pack interface is located on the bottom side of the main cavity 14. The main body 10 is provided with an opening 12 on the top wall 13, and the opening 12 communicates with the main cavity 14. The upper cover 20 is disposed at the opening 20 and protrudes from the top wall 13. Please refer to Figures 2 and Figure 3 simultaneously. An extended cavity 22 is formed in the upper cover 20. The extended cavity 22 is located above the main cavity 14 and is disposed higher than the main cavity 14. The extended cavity 22 communicates with the main cavity 14 through the opening 12.

[0035] The circuit board 30 includes a substrate 31 and components disposed on the substrate 31. The substrate 31 is disposed in the main cavity 14. The substrate 31 is in a plate shape and includes a first surface facing the upper cover 20 and a second surface opposite to the first surface. The components include a first group of components 32. The first group of components 32 is disposed on the first surface of the substrate 31 facing the upper cover 20, and the height of the first group of components 32 exceeds the inner surface of the top wall 13. The first group of components 32 protrudes upward through the opening 12, so that it will not be limited by the height of the top wall 13. The first group of components 32 is located within the projection coverage range of the upper cover 20 on the first surface, and the first group of components 32 protrudes upward into the extended cavity 22.

[0036] In a specific embodiment, the first group of components 32 includes an inductor and a capacitor. The inductor and the capacitor usually have a relatively large volume. By disposing the inductor and the capacitor on the first surface and protruding them upward into the extended cavity 22, the increase in the overall volume of the adapter caused by the inductor and the capacitor can be suppressed.

[0037] The battery pack adapter provided in this embodiment forms an extended cavity higher than the main cavity by setting an opening on the main body and a top cover protruding from the main body at the opening. The first set of components higher than the top wall of the main body can be centrally arranged in the area of the substrate corresponding to the opening and protrude upward into the extended cavity, so that the height of the main body can be made lower, and only the local top cover is highly convex, thereby suppressing the increase in the overall volume and making the battery pack adapter more compact and portable.

[0038] The battery pack interface attaches the battery pack in a sliding manner. Specifically, the battery pack interface 30 includes two parallel slide rails 17, which are arranged at the bottom of the main body 10, opposite to the top wall 13, and extend along the length direction of the main body 10. Correspondingly, two matching chutes are provided on the battery pack, and the length of the chutes is approximately the same as that of the slide rails 17. Align the two slide rails 17 with the chutes on the battery pack and apply a thrust along the direction of the slide rails, and the battery pack can be inserted into the battery pack interface along the slide rails and dock with the electrode seat 40, realizing the sliding plug-in connection between the battery pack and the adapter.

[0039] To suppress the adverse impact of the circuit board setting on the volume of the main body 10, the substrate 31 is arranged parallel to the slide rails 17. In this way, in the height direction, the substrate has the least impact on the increase in the height of the main body, which is convenient for making the height of the main body lower.

[0040] In one embodiment, all the components of the circuit board 30 are arranged on the first surface of the substrate 31. In other words, no components are arranged on the second surface of the substrate 31, and the components are centrally arranged on the first surface. In this way, the overall height of the circuit board can be made lower, which is beneficial to reducing the overall volume of the battery pack adapter.

[0041] In order to design the size of the main body to be more compact and small, in one embodiment, the top wall of the main body has an inclined transition structure, so that the outer shape of the main body is close to the internal structure, reducing space waste. Please refer to Figure 4 and Figure 5 As shown, the opening 12 is arranged in the middle area of the top wall 13. The top wall 13 includes an inclined surrounding wall 131, and the inclined surrounding wall 131 surrounds the opening 12 and is inclined to the first surface of the substrate 31. Along the direction perpendicular to the first surface, the inclined surrounding wall 131 extends obliquely from the outer edge towards the direction gradually approaching the opening 12. That is to say, the inclined surrounding wall 131 extends obliquely downward from the inner edge close to the opening 12 to the outside, and the inclined surrounding wall 131 is in the shape of a flared horn, making the main body volume more compact.

[0042] It can be understood that the small size of the top cover is also beneficial to the overall small and compactness. In a specific embodiment, please refer to Figure 3 and Figure 5, the projection of the upper cover 20 on the first surface of the substrate 31 is within the range of the first surface. Designing the upper cover so that its projection does not exceed the range of the first surface of the substrate can make the overall size more compact on the premise of covering the first group of components.

[0043] In order to suppress the influence of the upper cover on the overall volume of the adapter, in a specific embodiment, the top 21 of the upper cover 20 is flat, and the side wall 23 of the upper cover 20 extends obliquely downward around the top. The included angle between the side wall 23 of the upper cover and the top 21 is an obtuse angle. The top of the upper cover is flat, and the side wall adopts a flared shape that extends obliquely downward, making the appearance more beautiful and the volume more compact.

[0044] In order to facilitate the heat dissipation of the components, in an embodiment, the upper cover 20 is made of a first material, and the main body 10 is made of a second material. The thermal conductivity of the first material 20 is better than that of the second material. The upper cover is made of a material with better thermal conductivity, and the heat dissipated by the components can be conducted out better, which is beneficial to the heat dissipation of the components and ensures the normal operation and lifespan of the components.

[0045] Specifically, the upper cover 20 is made of aluminum. The main body 10 is made of plastic. Aluminum is a good conductor of heat, which can transfer heat quickly and conduct heat, suppressing the temperature rise of the components. Moreover, aluminum has a relatively small density, which is beneficial to suppressing the weight of the adapter.

[0046] In a specific embodiment, the main body 10 adopts a half-shell structure design, including a first half-shell 15 and a second half-shell 16. The first half-shell 15 and the second half-shell 16 are joined together along the width direction of the main body 10. Figure 3 Fig. shows a schematic side view structure of the battery pack adapter provided by an embodiment hiding the first half-shell. Please refer to Figure 2 As shown, after the first half-shell 15 and the second half-shell 16 are joined together, an opening 12 is formed at the joining seam of the first half-shell 15 and the second half-shell 16. The upper cover 20 is disposed at the opening 12, clamped between the first half-shell 15 and the second half-shell 16, covering the opening 12, and the upper cover 20 is positioned by the joining of the first half-shell 15 and the second half-shell 16.

[0047] The structures of the first half-shell 15 and the second half-shell 16 are substantially the same and are approximately symmetric about the joining surface. Notches are provided at the joining seams of the first half-shell 15 and the second half-shell 16. After the first half-shell 15 and the second half-shell 16 are joined together, the two notches are joined to form the opening 12, and the upper cover 20 is clamped and positioned at the opening 12. The main body adopts a half-shell structure design, and the upper cover is clamped and positioned at the joining seam of the two half-shells. After the two half-shells are fixed, the fixation of the upper cover can be achieved, which is convenient for assembly and molding.

[0048] Specifically, please refer to Figure 2, the upper cover 20 includes a first positioning portion 231 and a second positioning portion 232 provided at the outer edge of the side wall 23. Among them, the first positioning portion 231 is located at both ends of the upper cover 20 in the length direction, and is provided at the butting joint of the first half shell 15 and the second half shell 16. The first positioning portion 231 cooperates with both the first half shell 15 and the second half shell 16. The second positioning portion 232 is located on both sides of the upper cover 20 in the width direction. One side of the second positioning portion 232 cooperates with the first half shell 15, and the other side of the second positioning portion 232 cooperates with the second half shell 16.

[0049] More specifically, the first positioning portion 231 is configured as a rib, and the opening 12 is provided with a positioning groove corresponding to the butting joint of the first half shell 15 and the second half shell 16. The first positioning portion 231 is embedded in the positioning groove. The second positioning portion 232 is configured as a boss, and support platforms are provided on the corresponding wall surfaces of the first half shell 15 and the second half shell 16. The second positioning portion 232 is adapted to be inserted into the support platform, and the support platform plays a role in supporting and positioning the second positioning portion 232. Preferably, the number of the first positioning portions 231 is two, which are respectively provided at both ends of the upper cover 20 in the length direction. The number of the second positioning portions 232 is multiple, and they are basically evenly spaced on one side of the width of the side wall 23.

[0050] It should be noted that in the above embodiment, the main body 10 and the upper cover 20 are separately provided and connected by assembly. Those skilled in the art can think that the main body and the upper cover can also be integrally provided. The upper cover protrudes from the top wall of the main body, and the main cavity formed by the main body is communicated with the extended cavity formed by the upper cover. The first group of components with a height exceeding the inner surface of the top wall of the main body protrude into the extended cavity, so that the structure of the entire battery pack adapter is compact.

[0051] In one embodiment, please refer to Figure 5 As shown, a status display area 60 is further provided on the main body 10, which is used to display the charging and / or discharging status of the battery pack adapter. The status display area 60 is provided between the open end 22 and the insertion port (not shown) of the main body 10 for plugging in an external connector in the length direction of the main body 10. During or after the operation of the battery pack interface and the insertion port, the status display area 60 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 main body 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. Specifically, the status display area 60 is provided on the top wall 13 of the main body 10, on one side of the width direction of the upper cover 20. Setting the status display area 60 at the top wall 13 on one side of the width direction of the upper cover 20 is convenient for the status display area 60 to be arranged along the length direction of the main body 10. At the same time, the status display area 60 is located at the edge of the top wall 13 and close to the side wall of the main body 10, which is convenient for observation.

[0052] In order to facilitate the display of the numerical size or change of the status parameters of the battery pack adapter, in a specific embodiment, please refer to Figure 5 , the status display area 60 includes a plurality of display windows 61, and the plurality of display windows 61 are arranged in sequence along the length direction of the main body 10. Each display window 61 can be used to represent a certain amount of battery pack status parameters. The more the number of lit display windows 61, the larger the corresponding battery pack status parameter value. Exemplarily, the status parameter is to display the charging and / or discharging power of the battery pack adapter. Taking the scenario of charging the battery pack as an example, the display window 61 starts to be lit from one side. The greater the charging power, the more consecutive display windows 61 are lit until all the display windows 61 are lit, indicating that the battery pack is charging at full power. The display of the charging and / or discharging parameters of the battery pack facilitates the user to understand the charging status, so as to accurately predict the completion time of charging and discharging.

[0053] Obviously, the above-described embodiments are only a part of the embodiments of the present invention, rather than all of the 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 making creative efforts, and all of them should fall within the protection scope of the present invention.
