Description

Technical Field

[0001] This utility model relates to the field of battery technology, and more specifically, to an improved notebook battery. Background Technology

[0002] Laptops are playing an increasingly important role in people's daily lives, work, and studies. As the demand for laptops continues to increase, the requirements for laptop batteries are also constantly rising.

[0003] Currently, laptop batteries aim for larger capacity and longer battery life, while laptops themselves require thinner and lighter designs, thus limiting the space available for the battery compartment. With the battery compartment size remaining constant, existing laptop batteries typically use multiple identical cells to form a battery pack. These battery packs are generally regular in shape, and the connection method between the cells is simple, which is not conducive to the design layout of the battery compartment and affects the flexibility of the laptop's internal design. Utility Model Content

[0004] The purpose of this invention is to provide an improved laptop battery with a reasonable structure that allows for flexible combination of cells of different sizes, facilitating the layout and design of the battery compartment and improving the space utilization of the battery.

[0005] An improved laptop battery includes: a first battery pack, the first battery pack including a plurality of first cells arranged side by side and a motherboard connecting the plurality of first cells; and a second battery pack disposed on at least one side of the first battery pack, the second battery pack including a plurality of second cells, the top surface of the second cells being provided with a connecting flexible circuit board; the motherboard being provided with solder pads, one end of the connecting flexible circuit board being connected to the second cells, and the other end being provided with a soldering part, the soldering part being connected to the solder pads.

[0006] In the above technical solution, a first battery pack and a second battery pack are provided, both of which can use battery cells of different sizes, making the layout more flexible. The second battery pack is connected to the main board via a connecting flexible circuit board, thereby realizing series or parallel connection between battery packs. The connection method is simple and easy to assemble, and the shape of the connecting flexible circuit board can be adjusted according to actual needs to adapt to different battery compartments, further improving the layout flexibility while ensuring stable and reliable connection. The connecting flexible circuit board and the main board are welded together using solder joints and pads, resulting in a more stable connection, easier processing, and improved battery assembly efficiency.

[0007] Furthermore, the first battery cell includes a top seal portion, and the main board abuts against the top seal portions of a plurality of the first battery cells.

[0008] In the above technical solution, the motherboard and the top seal are brought into contact, which facilitates the connection between the motherboard and the first battery cell. The top seals of the multiple first battery cells provide support for the motherboard, thereby keeping the motherboard in a fixed position.

[0009] Furthermore, a side seal is formed between two adjacent first cells, and the main board is provided with an anti-cavity groove corresponding to the side seal.

[0010] In the above technical solution, in order to reduce the volume of the first battery cell, the aluminum-plastic film on both sides of the first battery cell is bent to the side to form a side seal. The motherboard can avoid the side seal from blocking the motherboard by setting a clearance groove, so that the motherboard and the top surface of the first battery cell abut against each other, thereby improving the stability of the motherboard structure.

[0011] Furthermore, at least one side of the clearance groove is provided with a reinforcing plate.

[0012] In the above technical solution, due to the presence of a clearance slot, the strength of the motherboard at the location corresponding to the clearance slot is weaker than that of other parts. By setting a reinforcing plate, the strength of the clearance slot can be increased, thereby improving the stability and reliability of the motherboard structure.

[0013] Furthermore, the first battery cell includes a first electrode tab, and the main board includes a plurality of connecting pieces, the connecting pieces being connected to the first electrode tab, and the connecting pieces and the first electrode tab being bent toward the top surface of the first battery cell.

[0014] In the above technical solution, the motherboard can be connected to the first electrode via a connecting piece to achieve connectivity and protection for the first battery cell. The connecting piece and the first electrode are bent towards the top surface of the first battery cell, which reduces the space occupied by the connection structure and improves the battery's space utilization rate.

[0015] Furthermore, it also includes several fixing pieces, which are sleeved on the outside of the connecting piece and the first electrode tab. Each fixing piece includes a first plate and a second plate opposite to each other, and the main plate and the top seal are sandwiched between the first plate and the second plate.

[0016] In the above technical solution, the fixing piece is sleeved on the outside of the connecting piece and the first electrode ear, which can protect the connection structure. The fixing piece clamps the top seal and the main board through the first plate and the second plate, thereby fixing the main board and the top seal to be connected. The structure is simple, easy to assemble, and the connection is stable.

[0017] Furthermore, the motherboard is provided with connectors for connecting external devices.

[0018] In the above technical solution, the motherboard can be connected to external devices via connectors.

[0019] Furthermore, the connecting flexible plate is provided with at least one positioning hole near the welding part.

[0020] In the above technical solution, the positioning holes can be used to position the connecting flexible board through the positioning holes of the external fixture when the welding part is welded to the welding pad, so as to ensure the stability of the welding position and improve the welding quality.

[0021] Furthermore, there is a height difference between the first battery pack and the second battery pack, and the connecting flexible plate is bent to form an extension that matches the height difference.

[0022] In the above technical solution, by setting an extension part on the connecting flexible board, it is possible to adapt to the height difference between battery packs, making the position layout between battery packs more flexible.

[0023] Furthermore, several fixing adhesive tapes are attached to the outer periphery of the first battery pack and the second battery pack.

[0024] In the above technical solution, the first battery pack and the second battery pack are fixed with adhesive tape, eliminating the need for a frame, which saves space and cost. At the same time, the adhesive tape can fix the battery to the laptop's battery compartment without the need for screws, avoiding the risk of screws falling out.

[0025] Compared with existing technologies, the advantages of this utility model are as follows: It includes a first battery pack and a second battery pack, both of which can use cells of different sizes, allowing for more flexible layout. The second battery pack is connected to the main board via a flexible connecting board, enabling series or parallel connection between battery packs. The connection method is simple and easy to assemble, and the shape of the flexible connecting board can be adjusted according to actual needs to adapt to different battery compartments, further improving layout flexibility while ensuring stable and reliable connection. The flexible connecting board and the main board are welded using solder joints and pads, resulting in a more stable connection and easier processing, thus improving battery assembly efficiency.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0033] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0034] Please refer to Figure 1 In a preferred embodiment, the improved notebook battery of this invention mainly includes a first battery pack 1 and a second battery pack 2. The first battery pack 1 includes a plurality of first battery cells 11 arranged side-by-side and a motherboard 12 connecting the plurality of first battery cells 11. The second battery pack 2 is located on at least one side of the first battery pack 1 and includes a plurality of second battery cells 21. A connecting flexible circuit board 22 is provided on the top surface of each second battery cell 21. The motherboard 12 has solder pads 121. One end of the connecting flexible circuit board 22 is connected to the second battery cell 21, and the other end has a soldering part 221 connected to the solder pad 121.

[0035] In this embodiment, there are two first battery cells 11, which are arranged adjacent to each other. In other possible embodiments, the number of first battery cells 11 can be set according to actual needs. The main board 12 can be a rigid printed circuit board, which is elongated and located on the top surface of the two first battery cells 11. Two first tabs 113 extend from the top surface of each first battery cell 11, and the two tabs are respectively connected to the positive and negative terminals of the first battery cell 11. The main board 12 is electrically connected to the tabs of each first battery cell 11.

[0036] In this embodiment, the second battery pack 2 is disposed on both sides of the first battery pack 1, with a second battery cell 21 on each side. The size of the second battery cell 21 is different from that of the first battery cell 11. In other embodiments, the second battery pack 2 can be disposed on one side of the first battery pack 1, and the number of second battery cells 21 can be set according to actual needs. The main board 12 has two sets of solder pads 121 at both ends, and each set of solder pads 121 includes two solder pads 121. The connecting flexible circuit board 22 can be an FPC (flexible printed circuit board). One end of the connecting flexible circuit board 22 is electrically connected to the tab of the second battery cell 21, and the other end has two soldering parts 221. The two soldering parts 221 are respectively connected to the positive and negative terminals of the second battery cell 21, and the two soldering parts 221 are respectively soldered to the corresponding solder pads 121, thereby connecting the second battery cell 21 and the main board 12.

[0037] As can be seen from the above technical solution, by providing a first battery pack 1 and a second battery pack 2, different sizes of battery cells can be used, making the layout more flexible. The second battery pack 2 is connected to the main board 12 via a connecting flexible circuit board 22, thereby realizing series or parallel connection between battery packs. The connection method is simple and easy to assemble, and the shape of the connecting flexible circuit board 22 can be adjusted according to actual needs to adapt to different battery compartments, further improving the layout flexibility while ensuring stable and reliable connection. The connecting flexible circuit board 22 and the main board 12 are welded together using a welding part 221 and a welding pad 121, resulting in a more stable connection, easier processing, and improved battery assembly efficiency.

[0038] Please refer to Figure 2 and Figure 3 The first battery cell 11 includes a top seal portion 111, and the main board 12 abuts against the top seal portions 111 of the plurality of first battery cells 11. For example, the top seal portions 111 extend upward perpendicularly to the top surface of the first battery cell 11, and the main board 12 is disposed on one side of the top seal portion 111, with one side surface of the main board 12 abutting against the top seal portion 111. By abutting the main board 12 against the top seal portions 111, the main board 12 can be easily connected to the first battery cells 11, and the top seal portions 111 of the plurality of first battery cells 11 provide support for the main board 12, thereby maintaining the fixed position of the main board 12.

[0039] Please refer to Figure 3 A side sealing portion 112 is formed between two adjacent first battery cells 11, and a clearance groove 122 is provided on the main board 12 corresponding to the side sealing portion 112. It should be noted that, in order to reduce the volume of the first battery cell 11, the aluminum-plastic film on both sides of the first battery cell 11 is bent to the side to form the side sealing portion 112. By setting the clearance groove 122, the main board 12 can avoid the side sealing portion 112 from blocking the main board 12, so that the main board 12 abuts against the top surface of the first battery cell 11, thereby improving the stability of the main board 12 structure.

[0040] In this embodiment, a reinforcing plate 123 is provided on at least one side of the clearance groove 122. Because of the clearance groove 122, the strength of the main board 12 at the location corresponding to the clearance groove 122 is weaker than other parts. By providing the reinforcing plate 123, the strength of the clearance groove 122 part can be increased, thereby improving the stability and reliability of the main board 12 structure.

[0041] Please refer to Figure 4 The first battery cell 11 includes a first tab 113, and the main board 12 includes several connecting pieces 124. The connecting pieces 124 are connected to the first tab 113, and the connecting pieces 124 and the first tab 113 are bent toward the top surface of the first battery cell 11. For example, the first tab 113 extends from the top seal 111, the connecting pieces 124 are fitted and connected to the first tab 113, and then the connecting pieces 124 and the first tab 113 are bent together toward the top surface of the first battery cell 11 to form a generally "U"-shaped structure. The main board 12 can be connected to the first tab 113 through the connecting pieces 124 to achieve communication and protection of the first battery cell 11. The bending of the connecting pieces 124 and the first tab 113 toward the top surface of the first battery cell 11 can reduce the space occupied by the connection structure and improve the space utilization rate of the battery.

[0042] This embodiment also includes several fixing plates 125, which are sleeved on the outside of the connecting plate 124 and the first electrode tab 113. Each fixing plate 125 includes a first plate 1251 and a second plate 1252 facing each other, with the main board 12 and the top sealing portion 111 sandwiched between the first plate 1251 and the second plate 1252. The fixing plates 125, sleeved on the outside of the connecting plate 124 and the first electrode tab 113, serve to protect the connecting structure. The fixing plates 125 clamp the top sealing portion 111 and the main board 12 through the first plate 1251 and the second plate 1252, thereby fixing the main board 12 and the top sealing portion 111 together. This design is simple, easy to assemble, and provides a stable connection.

[0043] It is understood that in other possible embodiments, the motherboard 12 may also be fixedly connected to the top seal 111 in other ways, such as by adhesive or double-sided tape.

[0044] In this example, the motherboard 12 is provided with a connector 126 for connecting external devices, and the motherboard 12 can connect to external devices through the connector 126. The connector 126 can adopt an existing structure, which will not be described in detail here.

[0045] The connecting flexible board 22 is provided with at least one positioning hole 222 near the welding part 221. In this embodiment, there are two positioning holes 222, which are arranged adjacent to each other. When the welding part 221 is welded to the pad 121, the positioning holes 222 of the external fixture can be used to position the connecting flexible board 222, ensuring the stability of the welding position and improving the welding quality.

[0046] In this embodiment, there is a height difference between the first battery pack 1 and the second battery pack 2, and the connecting flexible plate 22 is bent to form an extension 223 that matches the height difference. By providing the extension 223 on the connecting flexible plate 22, the height difference between the battery packs can be adapted, making the positional layout of the battery packs more flexible.

[0047] Please refer to this again. Figure 1 Several pieces of adhesive tape 3 are affixed to the outer periphery of the first battery pack 1 and the second battery pack 2. The first battery pack 1 and the second battery pack 2 are fixed by the adhesive tape 3, eliminating the need for a frame, which saves space and cost. At the same time, the tape can fix the batteries to the battery compartment of the laptop without the need for screws, avoiding the risk of screws falling out.
