[0002] The laptop battery is the main energy source for the operation of a laptop; in traditional laptop battery designs, it is generally a full-frame design or a frameless design.

[0003] A battery with a full plastic frame design encapsulates the battery from all sides. While this design offers good overall battery stability, the full-wrap design often results in a heavier battery, making it difficult to achieve lightweight design for both the battery and the laptop. This is especially true for most laptops on the market, which are designed for thin and light laptops.

[0004] While frameless batteries can effectively meet the requirements for lightweight design because they are not well encased and restrained, their overall structural strength and stability are poor, which can easily affect the overall quality and stability of the laptop after assembly.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0029] Example 1: Please see the appendix Figure 1-6 The encapsulation frame 10 of this utility model includes a top sealing plate 11 for encapsulating one end of the battery cell 20 where the tab is located, and a plurality of battery cell separator plates 12 disposed in the middle of the top sealing plate 11 for separating and reinforcing adjacent battery cells 20; and the top sealing plate 11 and the battery cell separator plates 12 are combined to form a T-shaped frame structure, which is combined with the encapsulation adhesive paper 40 to encapsulate a plurality of battery cells 20 to form a lightweight battery pack.

[0030] In this embodiment, the encapsulation frame 10 is formed by combining the top sealing plate 11 and the cell separator plate 12 to form a T-shaped frame structure, which is combined with the encapsulation paper 40 to encapsulate multiple cells 20. This not only effectively ensures the strength and stability of the encapsulated battery pack structure and improves the quality of the battery pack, but also effectively reduces the overall weight of the battery pack, thereby achieving a lightweight design of the battery pack.

[0031] Please refer to the appendix for further details. Figure 2 and 3 In some embodiments, the top sealing plate 11 includes a bottom sealing strip 111 for encapsulating and limiting the battery cell tabs and the PCB board 30 for electrically connecting multiple battery cells 20; a first side sealing strip 112 disposed on the side of the bottom sealing strip 111 away from the battery cell 20 for encapsulating and limiting the long side of the PCB board 30 for electrically connecting multiple battery cells 20; and second side sealing strips 113 disposed at both ends of the bottom sealing strip 111 for encapsulating and limiting the short side of the PCB board 30 for electrically connecting multiple battery cells 20. The bottom sealing strip 111, the first side sealing strip 112, and the second side sealing strip 113 combine to form a semi-enclosed structure with the top and the side adjacent to one end of the battery cell 20 open. The encapsulated structure formed by the three can connect and encapsulate the PCB board 30, while the open part after the three are combined can effectively facilitate the installation and limiting of the battery cell body and the PCB board 30. Preferably, the top sealing plate 11 has a plastic frame lug 13 on the side away from the battery cell 20 to facilitate the installation and positioning of the battery pack after encapsulation, as shown in the attached figure. Figure 1 As shown, the battery pack, after the encapsulating frame 10 encapsulates the battery cell 20, can be connected to the laptop host via the frame mounting ears 13, eliminating the need for screws. Compared to existing battery packs that require screws, this effectively prevents the laptop from operating normally due to loose screws falling inside the host.

[0032] Please refer to the appendix for further details. Figure 2 and 3 In some embodiments, the bottom seal 111 is provided with a first supporting reinforcing rib 1111 for supporting the PCB board 30. The design of the first supporting reinforcing rib 1111 can raise the PCB, which can not only effectively prevent the PCB board 30 from being too close to the bottom of the bottom seal 111, causing inconvenience in connecting the cell tabs, but also effectively prevent the height difference between the PCB board 30 and the cell tabs from being too large, thus preventing the tabs from being pulled and affecting the stability of the connection between the cell tabs and the PCB board 30. Preferably, the height of the first supporting reinforcing rib 1111 after supporting the PCB board 30 is less than the thickness of the cell 20; this can effectively ensure that after the encapsulation frame 10 encapsulates the cell tabs, the height of the encapsulation frame portion is greater than the thickness of the cell 20, thus ensuring the overall consistency and aesthetics of the battery pack.

[0033] Furthermore, the bottom seal 111 is provided with a second supporting reinforcing rib 1112 for supporting the battery cell tab. The design of the second supporting reinforcing rib 1112 can not only effectively reduce the height difference between the battery cell tab and the PCB board 30, but also effectively prevent the battery cell tab from being pulled by the excessive height difference between the PCB board 30 and the battery cell tab, thus affecting the stability of the connection between the battery cell tab and the PCB board 30. Moreover, the support of the second supporting reinforcing rib 1112 can also enable the battery cell tab to be electrically connected even if it is detached from the PCB board 30, so as to further improve the stability of the connection between the battery cell tab and the PCB board 30.

[0034] Please refer to the appendix for further details. Figure 3 In some embodiments, a limiting reinforcing rib 1121 for limiting the PCB board 30 is provided on the first side seal 112 and the second side seal 113, or on one of the first side seal 112 and the second side seal 113. The design of the limiting reinforcing rib 1121 can effectively prevent the PCB board 30 from moving, thereby further improving the stability of the connection between the cell tab and the PCB board 30, and thus effectively ensuring the overall stability of the battery pack after the encapsulation frame 10 encapsulates the cell 20.

[0035] Please refer to the appendix for further details. Figure 4 In some embodiments, the cell separator 12 includes a separator strip 121 for separating and limiting adjacent cells 20, and a reinforcing rib 122 protruding from the separator strip 121 for limiting the encapsulation tape 40. For example, when there are two separator strips 121, each separator strip 121 can be respectively disposed between two adjacent cells 20 for separating and limiting the three cells 20. Preferably, the height of the separator strip 121 is less than the thickness of the cell 20, which can not only effectively reduce the overall volume and weight of the encapsulation frame 10 while ensuring the stability of the cell 20 encapsulation, but also effectively prevent the surface of the battery pack from being uneven after encapsulation due to the separator strip 121 protruding from the surface of the cell 20. Furthermore, the height of the reinforcing rib 122 is greater than the thickness of the cell 20, meaning that the reinforcing rib 122 protrudes from the surface of the cell 20. This not only limits the position of the encapsulating tape 40, preventing it from shifting and thus ensuring the stability of the battery pack after encapsulation, but also effectively prevents and positions the adhesive tape 40 during application, thereby further improving the consistency, aesthetics, and stability of the battery pack after encapsulation.

[0036] Example 2: Please refer to the appendix for further details. Figure 5 and 6The battery pack of this embodiment includes multiple battery cells 20; a packaging frame 10 as described in Embodiment 1 for encapsulating and positioning the multiple battery cells 20; a PCB board 30 disposed on a top sealing plate 11 for electrically connecting the multiple battery cells 20; and packaging adhesive paper 40 bonded to the battery cells 20 and the packaging frame 10 for achieving lightweight packaging of the battery pack. Preferably, the electronic components of the PCB board 30 are disposed on the side facing the top sealing plate 11. When it is mounted on the top sealing plate 11, the electronic components can be concentrated between the PCB board and the top sealing plate 11, so that the side of the PCB board away from the top sealing plate 11 is kept as flat as possible; thereby making the surface of the packaged battery pack flat overall, effectively improving the consistency, aesthetics and flatness of the packaged battery pack.

[0037] Furthermore, the PCB board 30 is provided with a clearance groove, which not only allows the cell separator plate 12 of the encapsulation frame 10 to be cleared to avoid assembly interference, but also further limits the overall assembly of the PCB board 30 in the encapsulation frame 10 to prevent the stability of the overall battery pack assembly from being affected by the movement of the PCB board 30.

[0038] In this embodiment, the battery pack uses a T-shaped encapsulation frame 10 as the main support, and then uses encapsulation tape 40 for auxiliary fixation. Compared with the encapsulation frame 10, the weight of the encapsulation tape 40 is significantly reduced. Therefore, the battery pack formed by encapsulating the battery cell 20 using the encapsulation frame 10 and encapsulation tape 40 in this embodiment effectively meets the lightweight requirements of the battery compared with a battery with a full encapsulation frame design. Compared with a battery without an encapsulation frame design, it can effectively improve the overall structural strength and stability of the battery pack, thereby effectively ensuring the overall quality stability of the battery pack after it is assembled into the laptop, as well as the overall thin and light performance of the laptop.

[0039] Please refer to the appendix for further details. Figure 5 and 6 The encapsulation tape 40 includes a top sealing tape 41 bonded between the top sealing plate 11, the PCB board 30, and the ends of the battery cell 20 where the tabs are located; a side sealing tape 42 bonded to the side of the battery cell 20; a bottom sealing tape 43 bonded to the end of the battery cell 20 away from the battery cell tabs; and a reinforcing tape 44 bonded between the battery cell 20 and the battery cell separator plate 12. The top sealing tape 41 encapsulates the top of the battery pack, the side sealing tape 42 encapsulates the sides of the battery pack, the bottom sealing tape 43 encapsulates the bottom of the battery pack, and the reinforcing tape 44 improves the encapsulation strength of the battery pack. The encapsulation tape 40 can bond and fix multiple battery cells 20 that are electrically connected via the PCB board 30 and assembled within the encapsulation frame 10, replacing the use of the frame and connecting the battery cells 20, the PCB board 30, and the encapsulation frame 10 into a single, high-strength battery pack.

[0040] Furthermore, the reinforcing adhesive tape 44 includes a first reinforcing adhesive tape 441 bonded between the sides of two adjacent cells 20 and the cell separator 12 to improve the sealing strength of one side of the battery pack, and a second reinforcing adhesive tape 442 bonded between the surface of the cell 20 and the cell separator 12 to improve the sealing strength of the other side of the battery pack. Preferably, the second reinforcing adhesive tape 442 can be a trademark sticker, which not only improves the sealing strength of the battery pack, but also identifies the product information of the battery pack to facilitate subsequent assembly and use of the battery pack.

[0041] As can be seen from the technical solutions of the above embodiments, the present invention provides a packaging frame 10, which uses a top sealing plate 11 and a cell separator plate 12 to form a T-shaped frame structure, which is combined with the packaging adhesive paper 40 to package multiple cells 20. This not only effectively ensures the strength and stability of the packaged battery pack structure and improves the quality of the battery pack, but also effectively reduces the overall weight of the battery pack, thereby achieving a lightweight design of the battery pack.

[0042] This utility model also provides a battery pack, which is composed of multiple battery cells 20, PCB board 30, the above-mentioned encapsulation frame 10 and encapsulation paper 40. It can effectively combine the stability of the battery pack structure and the lightweight design, so that the laptop using this battery pack has good quality and thin and light performance.
