Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please refer to Figures 1 to 5 ,in, Figure 1 This is a schematic diagram of the structure of the battery charging device provided in this embodiment of the utility model; Figure 2 This is a three-dimensional structural diagram of the charging dock provided in an embodiment of the present utility model; Figure 3 This is a schematic diagram of the structure of the first power supply connection surface of the charging dock provided in this embodiment of the utility model; Figure 4 This is a structural schematic diagram of the non-power supply connection surface of the charging dock provided in this embodiment of the utility model; Figure 5 This is a schematic diagram of the structure of the second power supply connection surface of the battery pack provided in this embodiment of the present invention.

[0026] To address the problems in the prior art, this utility model provides a battery charging device, comprising: a charging base 1, the charging base 1 including at least two first power supply connection surfaces, the first power supply connection surfaces being provided with a connector 3 and a charging pin seat 4; and a battery pack 2, the battery pack 2 including a second power supply connection surface, the second power supply connection surface being provided with a connector 12 and a charging socket 10, the battery pack 2 and the charging base 1 being detachably connected via the connector 3 and the connector 12, and when the charging base 1 and the battery pack 2 are connected, the charging socket 10 is connected to the charging pin seat 4.

[0027] The charging dock 1 is used to charge the battery pack 2. It contains a power management circuit (transformer, rectifier, filter circuit, etc.) and a control circuit.

[0028] The charging dock 1 has at least two power supply connection surfaces. In this application, two first power supply connection surfaces are provided. The two first power supply connection surfaces can be arranged opposite each other or adjacent to each other. In this embodiment, they are arranged opposite each other.

[0029] Each power supply connection surface is equipped with a connector 3 and a charging pin socket 4. The connector 3 can mate with the connector 12 of the battery pack 2 to complete convenient and quick connection and disconnection, improving convenience. In addition, the charging pin socket 4 is located directly below the connector 3. When the connector 12 is connected to the connector 3, the charging socket 10 of the battery pack 2 can be connected to the charging pin socket 4 to complete charging.

[0030] In this way, the charging dock 1 can stably supply power to both battery packs 2 simultaneously through the two first power supply connection surfaces. Of course, if conditions permit, more power supply connection surfaces can be added to the charging dock 1 to connect more battery packs 2.

[0031] As an optional implementation, the connector 3 includes: a V-card connector block 301, which includes protrusions on both sides, and a V-shaped mounting space is formed in the middle of the protrusions on both sides; a button 304, one end of which passes through the side of the charging base 1 and contacts the elastic member 302, and the end is provided with a locking block 303, and the other end is located on the outside of the charging base 1; under normal conditions, the locking block 303 protrudes from one side of the protrusion of the V-card connector block 301 into the V-shaped mounting space; one end of the elastic member 302 contacts the button 304, and the other end contacts the inner wall of the V-card connector block 301.

[0032] V-card connector 301 includes two opposing bosses, the width of which gradually increases from top to bottom to form a V-shaped mounting space in the middle. This V-shaped mounting space serves as a slot that can cooperate with the connector 12 of the battery pack 2 to complete quick installation and removal.

[0033] One end of the button 304 penetrates through the side of the charging base 1 and has an end groove, while the other end is located on the outside of the charging base 1. One end of the elastic member 302 contacts the bottom of the end groove, and the other end of the elastic member 302 contacts the inner wall of the V-card connecting block 301. In addition, the end of the button 304 that penetrates into the charging base 1 is also provided with a locking block 303, which protrudes from the side of the nearest boss into the V-shaped mounting space.

[0034] Under normal conditions, when button 304 is not pressed, the elastic element 302 provides elastic force, causing the locking block 303 to protrude into the V-shaped mounting space. During mounting, the connector 12 of the battery pack 2 presses the locking block 303 into the boss. When installed in place, the spring provides restoring force, causing the locking block 303 to enter the slot of the connector 12 to complete the assembly. This ensures a quick and stable connection between the battery pack 2 and the charging base 1, preventing loosening even in the event of an external impact. During disassembly, pressing button 304 compresses the elastic element 302, causing the locking block 303 to retract into the boss. This allows the battery pack 2 to separate from the charging base 1, enabling quick disassembly of the battery pack 2.

[0035] As an alternative implementation, the elastic element 302 is a spring.

[0036] As an optional implementation, the connector 12 includes: the connector 12 is a V-card connector, the V-card connector is adapted to the V-shaped card mounting space, and the side of the V-card connector is provided with a groove, which corresponds to the card block 303.

[0037] In conjunction with the connector 3, the connector 12 is a V-shaped connector that fits into the V-shaped mounting space. The V-shaped connector has a groove on its side that corresponds to the locking block 303. When the V-shaped connector slides to the predetermined position in the V-shaped mounting space, the locking block 303 engages in the groove, completing the assembly. After assembly, the assembly will not be disengaged unless the side button 304 is pressed, improving assembly stability.

[0038] As an optional implementation, the charging base 1 includes: a main base 101, which is used for power supply, and a charging cover 5 is provided on the first power supply connection surface of the main base 101. The charging cover 5 is provided with a connecting seat 3 and a charging pin seat 4; and a base 102, on which the main base 101 is connected.

[0039] The charging dock 1 includes a main base 101 and a base 102. The cross-sectional area of ​​the base 102 is larger than that of the main base 101 to provide stable support. Certain sides of the main base 101 serve as first power supply connection surfaces. A charging cover 5 is provided on the first power supply connection surface. The charging cover 5 protrudes slightly from the side of the main base 101 to allow the button 304 to be inserted from the side. The connector 3 and the charging pin seat 4 are both connected to the surface of the charging cover 5.

[0040] As an optional implementation, the charging cover 5 is also provided with limiting posts on both sides to guide the installation of the battery pack 2.

[0041] As an optional implementation, the charging pin holder 4 includes: a PIN pin cover 401, which is connected to the charging holder 1; and a PIN pin 402, which protrudes from the top of the PIN pin cover 401 and is used to connect to the battery pack 2.

[0042] The PIN pin cover 401 is connected to the first power supply connection surface of the charging base 1 and is the external protection structure for the PIN pin 402. The PIN pin 402 protrudes from the top of the PIN pin cover 401 and can be connected to the interface of the charging socket 10 of the battery pack 2 to enable the charging base 1 to supply power to the battery pack.

[0043] As an optional implementation, the charging socket 10 includes a PIN connector, which is configured to correspond to the PIN pin 402.

[0044] The PIN connector is located on the second power supply connection surface of the battery pack 2. The PIN connector is located on the top of the base of the charging socket 10. After docking with the PIN 402, the battery pack 2 and the charging socket 1 are connected to the circuit to achieve electrical connection.

[0045] As an optional implementation, the charging dock 1 is provided with a quick-release connector 11 for mounting and connecting with an external device.

[0046] The non-power supply connection surface of the charging dock 1 is provided with a quick-release connector 11, which can be attached and connected to other external devices.

[0047] As an optional implementation, the quick-release connector 11 has the same structure as the V-card connector.

[0048] As an optional implementation, the charging dock 1 is equipped with a display screen, a power switch 7, and a charging port 6; the display screen is used to display charging parameters; the power switch 7 is used to control the start and stop of charging; and the charging port 6 is used to connect to an external power source.

[0049] The non-power supply connection surface of the charging base 1 has a charging port 6, which is a power socket, for connection to mains power. Pressing the power opening 7 starts the charging process, charging the battery pack 2 mounted on the charging base 1; pressing it again stops the charging process. The display screen shows the charging power and remaining charging time.

[0050] As an optional implementation, the non-power supply connection surface of the battery pack 2 is also provided with a charging display screen to display the remaining power, and also includes a power button. When the power button is pressed, the charging display screen displays the remaining battery power.

[0051] As an optional implementation, the charging base 1 is provided with air outlets 9 at the top and bottom respectively.

[0052] Air vents 9 are provided at the top and bottom of the charging base 1 to improve heat dissipation and extend service life.

[0053] As an optional implementation, the bottom of the charging base 1 is provided with a plurality of support legs 8; the support legs 8 are rotatably connected to the charging base 1 via a rotating shaft.

[0054] The charging base 1 has multiple rotatable feet 8 at its bottom, increasing the contact area between the charging base 1 and the outside, thereby enhancing stability. The angle of the feet 8 can be adjusted freely to meet different support needs. Furthermore, the bottom surface of the feet 8 can be equipped with anti-slip rubber pads to increase friction and thus improve support stability.

[0055] The above technical solution has the following beneficial effects: by opening multiple power supply connection surfaces on the charging base, the charging base can supply power to multiple battery packs simultaneously, thereby improving power supply efficiency; by setting a connector on the first power supply connection surface and a connector on the second power supply connection surface, the two can be quickly assembled, thereby improving the connection stability and assembly speed during charging.
