Description

Technical Field

[0001] This application relates to the field of notebook computer technology, and in particular to a battery mounting structure, a battery, and a notebook computer. Background Technology

[0002] Currently, laptops on the market can be broadly categorized into business laptops and gaming laptops. For business travelers, business laptops require portability, lightness, and small size, which dictates the shape and thickness of the battery. Gamers and esports enthusiasts have higher requirements for gaming laptops, needing to run demanding 3D and 2D games. Internal components such as the display, hard drive, motherboard, processor, and heatsink are larger, increasing the laptop's thickness. With limited internal space, the battery also needs to be thicker to meet capacity requirements.

[0003] As mentioned above, business laptops on the market are currently thinner, allowing for thinner batteries. Gaming laptops have more limited space, but there's room for improvement in thickness, allowing for thicker batteries. However, currently, a single battery for a laptop can only be used with one type of laptop, resulting in poor compatibility. Furthermore, developing two different battery types is costly and time-consuming. Utility Model Content

Detailed Implementation

[0035] The following detailed embodiments are provided to help the reader gain a comprehensive understanding of the methods, apparatus, and / or systems described herein. However, various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will be apparent after understanding the disclosure of this application. For example, the order of operations described herein is merely illustrative and is not limited to the order set forth herein; changes that will be apparent after understanding the disclosure of this application are possible, except for operations that must occur in a specific order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0036] The features described herein may be implemented in different forms and should not be construed as being limited to the examples described herein. Rather, the examples described herein have been provided merely to illustrate some of the many feasible ways of implementing the methods, apparatus, and / or systems described herein that will be apparent upon understanding the disclosure of this application.

[0037] Throughout the specification, when an element (such as a layer, region, or substrate) is described as being "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, it may be directly "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, or there may be one or more other elements in between. In contrast, when an element is described as being "directly on" another element, "directly connected to" another element, "directly bonded to" another element, "directly on" another element, or "directly covering" another element, there may be no other elements in between.

[0038] As used herein, the term “and / or” includes any one of the relevant items listed and any combination of any two or more items.

[0039] Although terms such as “first,” “second,” and “third” may be used herein to describe individual components, assemblies, regions, layers, or parts, these components, assemblies, regions, layers, or parts are not limited by these terms. Rather, these terms are used only to distinguish one component, assembly, region, layer, or part from another. Therefore, without departing from the teachings of the examples described herein, the first component, assembly, region, layer, or part referred to as the second component, assembly, region, layer, or part may also be referred to as the second component, assembly, region, layer, or part.

[0040] For ease of description, spatial relation terms such as “above,” “upper,” “below,” and “lower” are used herein to describe the relationship between one element and another, as shown in the accompanying drawings. Such spatial relation terms are intended to include not only the orientation depicted in the drawings but also different orientations of the device during use or operation. For example, if the device in the drawings is flipped, an element described as being “above” or “upper” relative to another element will subsequently be “below” or “lower” relative to that other element. Therefore, the term “above” includes both “above” and “below” orientations depending on the spatial orientation of the device. The device may also be positioned in other ways (e.g., rotated 90 degrees or in other orientations), and the spatial relation terms used herein will be interpreted accordingly.

[0041] The terminology used herein is for the purpose of describing various examples only and is not intended to limit this disclosure. Unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. The terms “comprising,” “including,” and “having” enumerate the stated features, quantities, operations, components, elements, and / or combinations thereof, but do not exclude the presence or addition of one or more other features, quantities, operations, components, elements, and / or combinations thereof.

[0042] Variations in the shapes shown in the accompanying drawings may occur due to manufacturing techniques and / or tolerances. Therefore, the examples described herein are not limited to the specific shapes shown in the accompanying drawings, but include changes in shape that may occur during manufacturing.

[0043] The features of the examples described herein can be combined in various ways that will be apparent upon understanding the disclosure of this application. Furthermore, although the examples described herein have a wide variety of constructions, other constructions are possible, as will be apparent upon understanding the disclosure of this application.

[0044] The first aspect of this application provides a battery mounting structure that solves the problem that existing laptop batteries can only be used in one type of laptop, resulting in poor versatility, and that the development of two different batteries is costly and time-consuming.

[0045] like Figure 1 , Figure 9 and Figure 11As shown, the battery mounting structure of this application includes a first frame 110, a second frame 120, and a hinge mechanism 200. The interiors of the first frame 110 and the second frame 120 are used to mount battery cells. The first frame 110 and the second frame 120 are hinged together by the hinge mechanism 200, allowing the battery mounting structure to switch between a folded state and an unfolded state. When the battery mounting structure is in the unfolded state, the first frame 110 and the second frame 120 are laid flat; when the battery mounting structure is in the folded state, the first frame 110 and the second frame 120 are stacked.

[0046] As described above, the battery mounting structure of this application, through a novel structural design, incorporates a hinge mechanism 200, making the battery mounting structure foldable. The shape of the battery mounting structure can be changed from a "flat state" to a "stacked state." That is, the battery mounting structure in the "flat state" is suitable for business laptops; the battery mounting structure in the "stacked state" is suitable for gaming laptops. The different shapes of the battery mounting structure in this application adapt to different computer systems, improving the versatility of the battery mounting structure for different computer systems and reducing development costs and time.

[0047] The following will introduce the first cell group 310, the second cell group 320, and the battery protection board, taking the installation of the first cell group 310, the second cell group 320, and the battery protection board within the battery mounting structure as an example, to describe in detail the battery mounting structure of this application embodiment. The first cell group 310 is disposed within the first frame 110, and the second cell group 320 is disposed within the second frame 120. Refer to the following... Figures 1 to 11 This application describes in detail the specific structures of the first frame 110, the second frame 120, the rotating shaft mechanism 200, the first cell group 310, the second cell group 320, and the battery protection board as described in some embodiments.

[0048] In the embodiments of this application, such as Figure 2 and Figure 3 As shown, both the first frame 110 and the second frame 120 of this application are rotatable about a first direction X via a rotating shaft mechanism 200. The first frame 110 includes a first bottom wall 111 and a first surrounding wall 112 surrounding the first bottom wall 111. The first bottom wall 111 includes a first portion 1111 and a second portion 1112, which are spaced apart in the first direction X. The first portion 1111 and the second portion 1112, together with the first surrounding wall 112, form two first receiving slots. As an example, the first battery cell assembly 310 includes two first battery cells 311, which are respectively disposed in two first receiving slots.

[0049] Similarly, such as Figure 2 and Figure 3As shown, the second frame 120 includes a second bottom wall 121 and a second enclosure wall 122 surrounding the second bottom wall 121; the second bottom wall 121 includes a fourth portion 1211 and a fifth portion 1212, which are spaced apart in a first direction X; the fourth portion 1211 and the fifth portion 1212, together with the second enclosure wall 122, respectively form two second receiving slots. As an example, the second battery cell assembly 320 includes two second battery cells 321, which are respectively disposed in two second receiving slots.

[0050] In the embodiments of this application, see also... Figure 2 and Figure 3 Both the first frame 110 and the second frame 120 are rectangular frames, and both the first battery cell 311 and the second battery cell 321 are rectangular cells. The first and second receiving slots have the same size. When the battery mounting structure is in the unfolded state, the two first receiving slots and the two second receiving slots are symmetrically arranged about the rotating shaft mechanism 200. This arrangement, as shown... Figure 9 and Figure 11 As shown, when the battery mounting structure is folded and in a "stacked state", the first frame 110 and the second frame 120 can overlap, which is more conducive to the miniaturization and integration of the battery mounting structure.

[0051] In the embodiments of this application, such as Figure 2 and Figure 10 As shown, the battery protection board of this application includes a first printed circuit board 510, a second printed circuit board 520, a flexible circuit board 530, and a connector 540. The first printed circuit board 510 is disposed within the first frame 110 and connected to two first battery cells 311. The second printed circuit board 520 is disposed within the second frame 120 and connected to two second battery cells 321. The flexible circuit board 530 is connected between the first printed circuit board 510 and the second printed circuit board 520. The connector 540 is connected to the first printed circuit board 510 and exposed outside the first frame 110.

[0052] The following text will be based on Figure 2 The specific installation positions of the first printed circuit board 510, the second printed circuit board 520, the flexible board 530, and the connector 540 are described for example.

[0053] like Figure 2 As shown, the first bottom wall 111 further includes a third portion 1113 disposed between the first portion 1111 and the second portion 1112; the second bottom wall 121 further includes a sixth portion 1213 disposed between the fourth portion 1211 and the fifth portion 1212. The first printed circuit board 510 can be disposed on the third portion 1113 and connected to the two first battery cells 311, and the second printed circuit board 520 can be disposed on the sixth portion 1213 and connected to the two second battery cells 321.

[0054] Furthermore, to facilitate the installation of the first battery cell 311, the second battery cell 321, the first printed circuit board 510, and the second printed circuit board 520, in the embodiments of this application, see... Figure 2 As shown, the third part 1113 is provided with two first limiting mechanisms 610. The two first limiting mechanisms 610 are spaced apart in the first direction X. The first printed circuit board 510 is limited between the two first limiting mechanisms 610. The ends of the two first cells 311 respectively abut against the two first limiting mechanisms 610.

[0055] Similarly, the sixth part 1213 is provided with two second limiting mechanisms 620, which are spaced apart in the first direction X. The second printed circuit board 520 is limited between the two second limiting mechanisms 620, and the ends of the two second battery cells 321 respectively abut against the two second limiting mechanisms 620. In this embodiment, the number of the first limiting mechanism 610 and the second limiting mechanism 620 is not limited. The number of the first limiting mechanism 610 and the second limiting mechanism 620 can also be four or six, with each pair forming a group and spaced apart in the first direction X. Each pair together limits the first printed circuit board 510 or the second printed circuit board 520.

[0056] like Figure 2 , Figure 9 and Figure 10 As shown, the flexible printed circuit board 530 is connected between the first printed circuit board 510 and the second printed circuit board 520, and it bends as the battery mounting structure folds. Figure 4 As shown, connector 540 is connected to first printed circuit board 510. The first enclosure 112 of first frame 110 has a notch for wiring connection between first printed circuit board 510 and connector 540, so that connector 540 is exposed outside of first frame 110.

[0057] As set above, see [link / reference] Figure 9 , Figure 10 and Figure 11 The battery protection board of this application combines a rigid-flex PCB design. The flexible PCB 530 is designed at the rotation center of the battery mounting structure, connecting to the rigid PCBs on both sides. A 180-degree rotation allows the battery mounting structure to fold into a hinge. Furthermore, the connector 540 is exposed on the outside of the first frame 110 for easy docking with the laptop's battery compartment.

[0058] Furthermore, in the embodiments of this application, such as Figure 3 and Figure 4As shown. A first protrusion 710 is provided on the third part 1113. The first protrusion 710 contacts the first printed circuit board 510, creating a gap between the first printed circuit board 510 and the third part 1113. Components are provided on the side of the first printed circuit board 510 facing the third part 1113. Similarly, a second protrusion 720 is provided on the sixth part 1213. The second protrusion 720 contacts the second printed circuit board 520, creating a gap between the second printed circuit board 520 and the sixth part 1213. Components are provided on the side of the second printed circuit board 520 facing the sixth part 1213.

[0059] With this configuration, the first boss 710 and the second boss 720 can not only provide support for the first printed circuit board 510 and the second printed circuit board 520, but the gap between the first printed circuit board 510 and the second printed circuit board 520 and the bottom wall (the third part 1113 and the sixth part 1213) can just accommodate the components.

[0060] Furthermore, in the embodiments of this application, such as Figure 2 and Figure 3 As shown, a first electrical connector 511 is provided on the side of the first printed circuit board 510 opposite to the third part 1113; the first tab 3111 of the first battery cell 311 extends from the end of the first battery cell 311 that abuts against the first limiting mechanism 610, and the first tab 3111 of the first battery cell 311 is connected to the first electrical connector 511. As an example, the first electrical connector 511 can be a nickel sheet. The first electrical connector 511 is provided on the side of the first printed circuit board 510 opposite to the third part 1113, which not only facilitates the connection of the first tab 3111, but also does not occupy the space on the other side of the first printed circuit board 510. Figure 2 The state after the first electrode 3111 is connected to the first electrical connector 511 is not shown in the figure.

[0061] Similarly, a second electrical connector 521 is provided on the side of the second printed circuit board 520 opposite to the sixth part 1213; the second tab 3211 of the second battery cell 321 extends from the end of the second battery cell 321 that abuts against the second limiting mechanism 620, and the second tab 3211 of the second battery cell 321 is connected to the second electrical connector 521. As an example, the second electrical connector 521 can be a nickel strip. The second electrical connector 521 is provided on the side of the second printed circuit board 520 opposite to the sixth part 1213, which not only facilitates the connection of the second tab 3211, but also does not occupy the space on the other side of the second printed circuit board 520. Figure 2 The state after the second electrode 3211 is connected to the second electrical connector 521 is not shown in the figure.

[0062] Furthermore, in the embodiments of this application, such as Figure 1 and Figure 4 As shown, the battery mounting structure also includes a first cover plate 410 and a second cover plate 420; the first cover plate 410 is disposed within the first frame 110, engages with the first limiting mechanism 610, is located between two first battery cells 311, and covers the first printed circuit board 510; the second cover plate 420 is disposed within the second frame 120, engages with the second limiting mechanism 620, is located between two second battery cells 321, and covers the second printed circuit board 520. Figure 4 As shown, taking the first limiting mechanism 610 as an example, the first limiting mechanism 610 may be provided with a locking hole, which is engaged with the buckle on the first cover plate 410.

[0063] As described above, the arrangement of the first cover plate 410 and the second cover plate 420 not only serves to fix and protect the first printed circuit board 510 and the second printed circuit board 520, but also enhances the overall strength of the first frame 110 and the second frame 120.

[0064] In the embodiments of this application, such as Figure 5 , Figure 6 and Figure 7 As shown, the rotating shaft mechanism 200 includes a rotating shaft plate 210, two first rotating shafts 220, and two second rotating shafts 230. The two first rotating shafts 220 are respectively connected to both ends of the rotating shaft plate 210, and the two second rotating shafts 230 are respectively connected to both ends of the rotating shaft plate 210, with both first rotating shafts 220 and second rotating shafts 230 extending along a first direction X. Two adjacent sides of the first frame 110 and the second frame 120 are provided with clearance notches, and these clearance notches together enclose a clearance space 130 for the rotating shaft plate 210 to be fitted into. Two adjacent sides of the first frame 110 and the second frame 120 are provided with shaft holes 113 exposed by the corresponding clearance notches. The first rotating shafts 220 and the second rotating shafts 230 are hinged to the corresponding first frame 110 or second frame 120 via the corresponding shaft holes 113.

[0065] In other words, the first frame 110 and the second frame 120 are connected by the middle pivot plate 210. The pivot plate 210 has four pivots, which are respectively assembled into the positioning shaft holes 113 of the two plastic frames by plastic interference fitting. The pivots can move and rotate in the holes.

[0066] Furthermore, in the embodiments of this application, such as Figure 7 and Figure 8As shown, both the first frame 110 and the second frame 120 are rectangular frames; when the battery mounting structure is in the unfolded state, two adjacent sides of the first frame 110 and the second frame 120 are defined as the first side S1; in the first frame 110 and the second frame 120, the two sides adjacent to the first side S1 are defined as the second side S2 and the third side S3, respectively. Figure 8 Taking the first frame 110 as an example; in the first frame 110, the first side S1 and the second side S2 of the first frame 110 are curved transitions, and the first side S1 and the third side S3 of the first frame 110 are right-angle transitions; in the second frame 120, the first side S1 and the second side S2 of the second frame 120 are curved transitions, and the first side S1 and the third side S3 of the second frame 120 are right-angle transitions.

[0067] like Figure 5 and Figure 8 As shown, the bottom of the adjacent sides of the first frame 110 and the second frame 120 are designed with right-angled edges, allowing the pivot to rotate only in one direction. The single-sided rounded design at the top ensures that the first frame 110 and the second frame 120 can only be folded together via the pivot and cannot rotate in the opposite direction, as the right-angled edges limit their movement. This design allows the battery mounting structure to be folded from a "stacked state" to a "flat state" more easily to a 180° angle due to the right-angled edges. Furthermore, once flattened to 180°, the first frame 110 and the second frame 120 are less prone to bending or rotating due to external forces.

[0068] Furthermore, such as Figure 6 and Figure 7 As shown, when the battery mounting structure is in the unfolded state, the two sides of the rotating shaft plate 210 adjacent to the first frame 110 and the second frame 120 are provided with guide arc surfaces 211 for the first frame 110 and the second frame 120 to rotate. The guide arc surfaces 211 facilitate the unidirectional rotation of the first frame 110 and the second frame 120.

[0069] Furthermore, such as Figure 6 and Figure 7 As shown, the pivot plate 210 also adopts a single-sided arc edge design, that is, the top of the pivot plate 210 has a single-sided arc edge design, and the bottom has a right-angle edge design. Through the right-angle edge limitation, the first frame 110 and the second frame 120 can only be folded in half and cannot rotate in the opposite direction. Similarly, when the shape of the battery mounting structure is folded from the "stacked state" to the "flat state", it is easier to lay flat to 180° because it is limited by the right-angle edge. And after laying flat to 180°, the first frame 110 and the second frame 120 are not easily bent or rotated by themselves due to external forces.

[0070] Optionally, in embodiments of this application, such as Figure 3As shown, the middle portions of the first part 1111 and the second part 1112 of the first bottom wall 111, as well as the middle portions of the fourth part 1211 and the fifth part 1212 of the second bottom wall 121, are all hollow structures. Figure 1 As shown, when the battery mounting structure is in its unfolded state, the battery mounting structure includes a front side and a back side that are opposite each other in its thickness direction. Both the front side and the back side can be provided with an insulating film (the insulating film is not shown in the figure). In this embodiment, trademarks can be provided on the insulating films on both the front side and the back side. The insulating film is, for example, wrapped with Mylar film.

[0071] In summary, the battery mounting structure of this application, through a novel structural design, adds a hinge mechanism 200 between the first frame 110 and the second frame 120 of the battery mounting structure, and combines a rigid-flex battery protection board, making the battery mounting structure foldable. The shape of the battery mounting structure can be changed from a "flat state (butterfly shape)" to a "stacked state (dragonfly shape)." That is, the battery mounting structure in the "flat state" is suitable for business laptops; the battery mounting structure in the "stacked state" is suitable for gaming laptops. The different shapes of the battery mounting structures in this application adapt to different computer systems, improving the adaptability and versatility of the battery mounting structure to computer systems, and reducing development costs and time.

[0072] like Figure 1 As shown, the "butterfly-shaped" structure consists of four battery cells arranged in a grid pattern, with a battery protection board placed between them. The front and back are wrapped with Mylar film, and the thickness of the entire battery mounting structure mainly depends on the thickness of a single battery cell. Figure 11 As shown, the "dragonfly" structure also consists of 4 battery cells with a battery protection board arranged between them. However, unlike the "butterfly" structure, the "dragonfly" structure is a stacked structure in pairs, and the thickness of the entire battery mounting structure mainly depends on the thickness of the two battery cells.

[0073] According to a second aspect of this application, a battery is provided, comprising a battery mounting structure as described above, and a first cell group 310, a second cell group 320, and a battery protection board disposed within the battery mounting structure.

[0074] According to a third aspect of this application, a laptop computer is provided, including the battery described above.
