In order to meet the different voltage and current requirements of different devices, battery packs usually need to have flexible voltage and current output capabilities.

[0003] However, traditional single battery packs often cannot meet the needs of flexible voltage and current output capabilities. In addition, the connection between the battery and the device has always been an important technical concern. Although traditional battery connection methods, such as screw fixing and welding, meet the needs of battery connection to a certain extent, they still have some limitations in practical applications. Summary of the invention

[0006] Optionally, a group of symmetrical plug holes are formed through the two side surfaces of the circuit board, and the electrode plug pieces are inserted and connected inside the plug holes.

[0007] Optionally, after the upper shell cover is connected to the battery pack base shell, the inner surface of the upper shell cover abuts against the upper surface of the double-head connector body.

[0008] Optionally, the upper shell cover is provided with a group of symmetrical heat dissipation grooves at a central position corresponding to the double-head connector body.

[0009] Optionally, the positive contact plane is located on two side surfaces of the double-ended connector body close to the center.

[0010] Optionally, the side contact plane is located at a contact plane where the spring piece abuts against the card insert plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] The utility model utilizes the use of a double-headed plug-in sheet body. Firstly, the double-plug-in sheet technology can realize flexible series and parallel connection of the battery pack, thereby meeting the voltage and current requirements of different devices. The technology is equipped with a protection mechanism to ensure the safe operation of the battery pack and prevent safety accidents caused by abnormal conditions. Secondly, the plug-in structure is made of high-quality materials and has good durability and stability, which can ensure the long-term stable operation of the battery pack, thereby improving the safety and flexibility of the use of the double-plug-in sheet structure of the battery pack.

[0013] 2. The utility model uses the front contact plane and the side contact plane formed by the upper shell cover and the card plug-in plate, so that during the installation and removal process, the user only needs to insert the electrode plug-in of the double-headed plug-in piece body into the circuit board, and then cover and connect the upper shell cover to the connection point of the battery pack base shell to complete the installation and removal. While the upper shell cover is being covered, the card plug-in plate contacts the front contact plane and the side contact plane, forming an installation abutment with three elastic force points on one side. Since the front contact plane and the side contact plane are pressed by the elastic force of the card plug-in plate, the elastic sheet of the double-headed plug-in piece body is also squeezed and stabilized by elastic force. The entire installation process can be completed without professional technicians, making maintenance and replacement of batteries more convenient and quick, reducing maintenance costs. The plug-in connection is easy and fast to install, reducing installation costs, and also reducing the possibility of operating errors. In addition, the double-plug-in piece structure can achieve more reliable electrical connection, reduce safety hazards caused by poor contact or short circuit, etc., thereby further improving the safety and flexibility of the use of the double-plug-in piece structure of the battery pack.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] For examples, see Figures 1 to 6 , the utility model provides the following technical solution:

[0023] A battery pack double-plug-in sheet structure comprises a battery pack base shell 1, wherein a battery pack 3, a circuit board 4 and a group of symmetrical double-end plug-in sheet bodies 5 are respectively installed and connected inside the battery pack base shell 1.

[0024] The dual-plug technology can realize flexible series and parallel connection of battery packs, thereby meeting the voltage and current requirements of different devices. This technology is equipped with a protection mechanism to ensure the safe operation of the battery pack and prevent safety accidents caused by abnormal conditions. Secondly, the plug-in structure is made of high-quality materials with good durability and stability, which can ensure the long-term stable operation of the battery pack, thereby improving the safety and flexibility of the use of the dual-plug structure of the battery pack.

[0025] An upper shell cover 2 is fixedly installed on the upper surface of the battery pack base shell 1. After the upper shell cover 2 is connected to the battery pack base shell 1 by clamping, the inner surface of the upper shell cover 2 abuts against the upper surface of the double-head plug-in sheet body 5. Both ends of the double-head plug-in sheet body 5 are fixedly connected with spring pieces 9 in an M shape. Electrode plugs 7 are symmetrically connected to both sides of the lower surface of the double-head plug-in sheet body 5. The electrode plugs 7 are inserted through the inside of the circuit board 4. A group of symmetrical plug holes 8 are opened on the two side surfaces of the circuit board 4, and the electrode plugs 7 are inserted and connected inside the plug holes 8. A card plug board 12 for clamping and fixing the two side surfaces of the double-head plug-in sheet body 5 is fixedly connected to the lower surface of the upper shell cover 2, and after the card plug board 12 is clamped with the upper shell cover 2, a positive contact plane 6 and two side contact planes 10 are respectively formed on both sides of the double-head plug-in sheet body 5. The positive contact plane 6 is located on the two side surfaces of the double-head plug-in sheet body 5 close to the center, and the side contact planes 10 are located on the contact planes where the spring pieces 9 fit and abut against the card plug board 12.

[0026] More specifically, in the present embodiment, during the installation and removal process, the user only needs to insert the electrode plug 7 of the double-ended plug-in sheet body 5 into the circuit board 4, and then cover the upper shell cover 2 and connect it to the connection point of the battery pack base shell 1 to complete the installation and removal. While the upper shell cover 2 is being covered, the card plug-in plate 12 contacts the front contact plane 6 and the side contact plane 10, forming an installation abutment with three elastic points on one side. Since the front contact plane 6 and the side contact plane 10 are pressed by the elastic force of the card plug-in plate 12, the spring piece 9 of the double-ended plug-in sheet body 5 also forms an elastic squeeze and stability. The entire installation process can be completed without the need for professional technicians, making maintenance and replacement of batteries more convenient and quick, reducing maintenance costs, and the plug-in connection has the characteristics of easy and fast installation, reducing installation costs, and also reducing the possibility of operating errors. In addition, the double plug-in sheet structure can achieve more reliable electrical connection, reduce safety hazards caused by poor contact or short circuit, thereby further improving the safety and flexibility of the use of the double plug-in sheet structure of the battery pack.

[0027] Furthermore, a group of symmetrical heat dissipation slots 11 are formed on the upper shell cover 2 at the center position corresponding to the double-ended plug body 5 .

[0028] It is worth noting that the heat dissipation slot 11 can provide a heat dissipation effect for the use of the double-ended plug-in sheet body 5 .

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
