[0030] Reference Figures 1 to 5 The present invention aims to provide an embodiment of a digital battery charger, while referring to... Figure 6 The present invention also aims to provide an embodiment of a charging method.

[0031] In this embodiment, the digital battery charger includes a charger body 100 and a flip cover 280. The charger body 100 has an upper open cavity 270, and the flip cover 280 is rotatably connected to the side wall of the upper open cavity 270. When the flip cover 280 is rotated, the flip cover 280 can open the upper open cavity 270, making it convenient to take out the battery from the upper open cavity 270 for use, or to put the battery into the upper open cavity 270 for charging.

[0032] In some specific embodiments of the present invention, the charger body 100 may have a self-locking snap 290 that connects to the flip cover 280. By pressing the flip cover 280, the self-locking snap 290 locks and unlocks the flip cover 280, eliminating the need for a handle and other structures, and simplifying the appearance.

[0033] Reference Figure 2 The charger body 100 includes an upper shell 110 and a lower shell 120. The upper shell 110 and the lower shell 120 cooperate to form an internal space, which can be used to install the charging motherboard 330 and other components, while isolating the charging motherboard 330 and other components from the outside world, making them less susceptible to damage.

[0034] In this embodiment, the upper shell 110 of the main body forms an upper open cavity 270, which is used to accommodate the battery and also to prevent the battery from being exposed and damaged by impact.

[0035] In some specific embodiments of the present invention, the upper open cavity 270 may have an upper open side and an obliquely upper open side to facilitate the removal and placement of the battery.

[0036] In some specific embodiments of the present invention, when the flip cover 280 is closed, the upper open cavity 270 can accommodate the flip cover 280, improving the sealing performance and preventing the flip cover 280 from being damaged by bumps.

[0037] To address the issue of diverse battery connection ports leading to a wide variety of digital chargers, in this embodiment, the charger body 100 includes a battery mounting portion 130 and a charging mounting portion 140, with the battery mounting portion 130 used to mount the battery. The digital battery charger also includes a charging connector 360, which is detachably mounted to the charging mounting portion 140 and has a charging connector 150 conductively connected to the battery and a power supply conductive portion 160 conductively connected to the charging connector 150.

[0038] In some specific embodiments of the present invention, the charging connection part 150 can be a socket or a strip to meet the needs of connecting the battery. Moreover, the position of the charging connection part 150 on one side of the charging connection base 360 ​​can be adjusted according to the battery configuration.

[0039] Reference Figure 2 The present invention also provides five types of charging connectors 360 to meet the charging needs of various batteries.

[0040] Meanwhile, the charger body 100 is provided with a power conductive part 170, which is connected to the power supply conductive part 160 so that electrical energy is transmitted to the battery through the power conductive part 170, the power supply conductive part 160 and the charging connection part 150.

[0041] In some specific embodiments of the present invention, a charging motherboard 330 may be provided inside the charger body 100. The charging motherboard 330 is provided with a power connection interface 340 and a power conductive part 170. The power connection interface 340 is used to connect to a power source, and the power conductive part 170 includes a conductive spring pin erected on the charging motherboard 330.

[0042] It is easy to understand that this embodiment, through the power connection interface 340, can also be conveniently charged by connecting a regular charging cable, and can be shared with the chargers of mobile phones and other electronic devices, reducing purchase and carrying costs.

[0043] It is easy to understand that this example uses a conductive spring pin to ensure that the power supply conductive part 170 continuously contacts the power supply conductive part 160, thereby preventing current transmission interruption and avoiding problems such as battery overheating caused by current transmission interruption.

[0044] In some specific embodiments of the present invention, the power supply conductive part 170 and the power supply conductive part 160 can be made to abut against each other vertically, and it is also convenient to use gravity to maintain contact, making them less likely to separate and improving the reliability of conductivity.

[0045] In some specific embodiments of the present invention, the battery mounting part 130 may include a battery cavity, and the charging mounting part 140 may include a disassembly cavity communicating with the battery cavity, with the tops of the battery cavity and the disassembly cavity being open.

[0046] It is easy to understand that this embodiment, by setting up a battery cavity and a disassembly cavity, can meet the installation needs of the battery and the charging connector 360.

[0047] Meanwhile, the battery compartment and the disassembly compartment are connected, facilitating a 360° conductive connection between the battery and the charging connector to meet the needs of power transmission.

[0048] In some specific embodiments of the present invention, the charger body 100 may have an upper open cavity 270, and the bottom of the upper open cavity 270 is provided with a battery cavity and a disassembly cavity. The upper open cavity 270 is larger than the battery cavity and the disassembly cavity, and also provides space for finger movement, which makes it convenient for fingers to pick up the battery and the charging connector 360, reducing the difficulty of use and improving the convenience of use.

[0049] Reference Figure 2 and Figure 3 In some specific embodiments of the present invention, a side limiting protrusion 180 may be provided on the top of an inner sidewall of the disassembly cavity, and a side limiting groove 190 for accommodating the side limiting protrusion 180 may be provided on the charging connector 360, with the side limiting groove 190 facing upwards and open.

[0050] It is easy to understand that, by setting the side limiting protrusion 180 and the side limiting groove 190, the present invention also facilitates the upper and lower limiting of the side limiting protrusion 180 and the side limiting groove 190, thereby fixing one side of the charging connector 360, while eliminating the need for screws, simplifying the disassembly and assembly process, and making it easy to operate.

[0051] In some specific embodiments of the present invention, the side limiting protrusion 180 can be formed by the top-mounted structure of the injection mold, without the need to add structures such as inclined blocks, which simplifies the injection mold structure, reduces manufacturing costs, and improves mold reliability.

[0052] The side limiting groove 190 in this embodiment can also limit the charging connector 360 in two horizontal directions to prevent it from swinging and detaching from the battery.

[0053] In this example, the positions of the side limiting protrusion 180 and the side limiting groove 190 can be interchanged. For example, the side limiting protrusion 180 is set on the charging connector 360, and the side limiting groove 190 is set on the charger body 100. That is, the side limiting groove 190 is set on the upper shell 110 of the body.

[0054] Reference Figure 2 and Figure 3 In some specific embodiments of the present invention, one of the side wall of the disassembly cavity and the charging connector 360 may be provided with a disassembly slot 200, and the other of the side wall of the disassembly cavity and the charging connector 360 may be provided with a disassembly pin 210 and a disassembly spring 350 that drives the disassembly pin 210 to engage with the disassembly slot 200.

[0055] In this embodiment, the disassembly and assembly slot 200 is provided in the charging connector 360, and the disassembly and assembly pin 210 and the disassembly and assembly spring 350 are provided in the side wall of the disassembly and assembly cavity or the charger body 100. This also helps to reduce the volume of the charging connector 360, avoids the large size and complex structure of the charging connector 360 caused by setting the disassembly and assembly pin 210 and the disassembly and assembly spring 350, and also helps to make full use of the internal space of the charger body 100.

[0056] It is easy to understand that by moving the disassembly and assembly pin 210 to separate the disassembly and assembly pin 210 from the disassembly and assembly slot 200, the charging connector 360 can be removed. After the charging connector 360 is inserted into the disassembly and assembly cavity, the disassembly and assembly pin 210 is released, and the disassembly and assembly spring 350 drives the disassembly and assembly pin 210 to return to its original position, so that the disassembly and assembly pin 210 is inserted into the disassembly and assembly slot 200, thus fixing the charging connector 360.

[0057] The complete disassembly and assembly steps for the charging connector 360 are as follows: First, insert one end of the charging connector 360 with the side limiting groove 190 into the disassembly / assembly cavity. Then, move the charging connector 360 so that the side limiting groove 190 is at the bottom of the side limiting protrusion 180. Rotate the charging connector 360 so that the side limiting protrusion 180 engages with the side limiting groove 190. Move the disassembly / assembly latch 210 away from the disassembly / assembly cavity. Continue rotating the charging connector 360 so that one end of the charging connector 360 with the disassembly / assembly slot 200 also enters the disassembly / assembly cavity. Release the disassembly / assembly latch 210. The disassembly / assembly spring 350 drives the disassembly / assembly latch 210 to reset, allowing the disassembly / assembly latch 210 to insert into the disassembly / assembly slot 200, thus fixing the charging connector 360 in place.

[0058] In some specific embodiments of the present invention, the side limiting protrusion 180 and the side limiting groove 190, the disassembly and assembly pin 210 and the disassembly and assembly slot 200 can be located at both ends of the length direction of the charging connector 360 to improve the fixing effect. At the same time, it is convenient for the charging connector 360 to be rotated in and out.

[0059] In some specific embodiments of the present invention, the disassembly and assembly pin 210 may have a radial manual toggle portion, which facilitates the finger toggle the disassembly and assembly pin 210.

[0060] In some specific embodiments of the present invention, the disassembly and assembly pin 210 can be hollow and open toward the disassembly and assembly spring 350, which reduces the manufacturing difficulty. At the same time, it also facilitates the end limit of the disassembly and assembly spring 350 and reduces the installation difficulty of the disassembly and assembly spring 350.

[0061] Reference Figure 2 and Figure 4In some specific embodiments of the present invention, the side wall of the battery cavity may be provided with a battery pusher 220 and a pusher spring 230 for moving the battery pusher 220. The battery pusher 220 is located on the side of the battery cavity opposite to the disassembly cavity. The battery pusher 220 is used to push the battery so that the battery is connected to the charging connection part 150.

[0062] It is easy to understand that, under the action of the pusher spring 230, the battery pusher 220 pushes the battery toward the charging connector 360, so that the battery is connected to the charging connector 360 and the charging connector part 150 of the charging connector 360, so as to continuously charge.

[0063] In some specific embodiments of the present invention, a bottom pressing member 240 may be provided, which forms a moving track for the battery pusher 220 to meet the movement requirements of the battery pusher 220. At the same time, it simplifies the structure of the upper shell 110 of the main body and reduces the manufacturing difficulty.

[0064] In some specific embodiments of the present invention, the bottom pressure member 240 can be hollow, which facilitates the formation of the moving track of the battery pusher 220 and reduces the space occupied.

[0065] In some specific embodiments of the present invention, notches can be provided on both sides of the bottom pressing member 240, and snap-fit ​​strips are formed in the notches. The snap-fit ​​strips snap-fit ​​with the opening of the upper shell 110 of the main body, which can complete the fixation of the bottom pressing member 240 and reduce the number of parts.

[0066] Reference Figure 5 In some specific embodiments of the present invention, the sidewall of the battery cavity may be provided with a side push block 250 and a side push spring 260 for moving the side push block 250. There are two sets of side push blocks 250, which are located on opposite sides of the battery cavity. The two sets of side push blocks 250 are used to define the position of the battery in a direction perpendicular to the line connecting the battery cavity and the disassembly cavity.

[0067] It is easy to understand that by setting the side push block 250 and the side push spring 260, this embodiment can also facilitate the limiting and fixing of the left and right sides of the battery, avoid the battery shifting to the left and right and causing the battery to be misaligned with the charging connection part 150 and unable to charge, and also help to fix the battery and reduce shaking.

[0068] In some specific embodiments of the present invention, the side push block 250 can be hollow and face the side push spring 260, which can reduce manufacturing difficulty and facilitate the installation and limiting of the side push spring 260.

[0069] Reference Figure 4 and Figure 5In some specific embodiments of the present invention, the flip cover 280 may be provided with a top pressing block 300 and a pressing spring 310 that drives the top pressing block 300 to press the battery. Under the action of the pressing spring 310, the top pressing block 300 presses the top of the battery, preventing the battery from moving up and down and coming out. This can effectively fix the battery and prevent charging interruption or battery damage.

[0070] In some specific embodiments of the present invention, a top pressing member 320 may be provided. The top pressing member 320 is frame-shaped and has mounting ears. The mounting ears are provided with screws that connect to the flip cover 280 to fix the top pressing member 320. At the same time, the interior of the top pressing member 320 forms a moving track for the top pressing block 300 and a mounting space for the pressing spring 310, which simplifies the setting of the top pressing block 300 and the pressing spring 310. In addition, the top pressing member 320 and the flip cover 280 are manufactured separately, which reduces the manufacturing difficulty.

[0071] In some specific embodiments of the present invention, the upper shell 110 and the lower shell 120 of the main body can be used to define the push spring 230, the side push spring 260 and the disassembly spring 350, thereby reducing the difficulty of manufacturing and assembly.
