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] The battery bracket and battery cover are two important components of the entire laptop battery. They determine the external dimensions of the laptop battery and also ensure the overall strength of the laptop battery. Therefore, the fixing structure of the battery bracket and battery cover is very important for the entire laptop battery.

[0003] like Figure 10 As shown, the battery bracket and battery cover are currently fixed by clips, and the battery protection board (PCB) is limited between two clips. However, because the clips occupy a large area, the width of the soldering terminal lines at the head of the PCB is limited, which makes the solder pads on both sides too close to the edge of the PCB. When applying adhesive (conformal coating adhesive) to the solder pads and terminal lines later, it not only affects the adhesive application process, but also poses a risk of adhesive overflow at the edge of the PCB, affecting the performance of the entire laptop battery, as well as employee work efficiency and product yield.

[0019] Based on the above technical features, the beneficial effects of this application are as follows:

[0020] This application replaces the original battery bracket and battery cover with a new fixing structure that uses a snap-fit ​​mechanism, allowing the end of the circuit board (e.g., the head) to be inserted into the receiving portion of the battery bracket head.

The extra width on both sides of the circuit board head can be inserted into the receiving space of the battery bracket, which effectively avoids the problem of the limited width of the circuit board head caused by the existence of the snap-fit ​​structure in the prior art. It also solves the problem of insufficient width during the later glue application process and the risk of glue overflowing onto the circuit board, thereby improving work efficiency and product yield.

Detailed Implementation

[0036] 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.

[0037] 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.

[0038] 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.

[0039] As used herein, the term “and / or” includes any one of the relevant items listed and any combination of any two or more items.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] Prior to the filing of this application, if Figure 10 As shown, the battery bracket and battery cover are currently fixed by clips, and the battery protection board (PCB board 10) is limited between two clips 20. However, because the area occupied by the clips 20 is large, the width of the soldering terminal line at the head of the PCB board 10 is limited, which makes the solder pads 30 on both sides too close to the edge of the PCB board 10. When applying glue (conformal coating glue) to the solder pads 30 and terminal line later, it not only affects the glue application work, but also poses a risk of glue overflow at the edge of the PCB board 10, affecting the performance of the entire laptop battery, employee work efficiency, and product yield.

[0046] In view of this, the first aspect of this application provides a battery mounting structure, thereby solving the problem that the current battery bracket and battery cover are fixed by clips, and the battery protection board (PCB board) is limited between two clips, the clips occupy a large area, which leads to the limitation of the width of the soldering terminal line at the head of the PCB board.

[0047] The following reference Figures 1 to 9 The present application describes a battery mounting structure according to some embodiments. For ease of description, the following description will refer to a first direction X, a second direction Y, and a third direction Z that are mutually perpendicular to each other in the battery mounting structure. Here, perpendicularity can be 90° ± 5°.

[0048] The battery mounting structure of this application includes a battery bracket 100 and a battery cover 300. The following will introduce a battery cell and a circuit board 700, using the installation of the battery cell and circuit board 700 within the battery mounting structure as an example to describe the battery mounting structure of an embodiment of this application in detail.

[0049] like Figures 2 to 7 As shown, the battery holder 100 includes a base plate 1212 extending along a first direction X and a fixing structure 200 disposed on the base plate 1212; a circuit board 700 extends along the first direction X and is disposed on the base plate 1212, the circuit board 700 including a head 710 and a tail portion that are opposite to each other in the first direction X; the base plate 1212 includes a head end and a tail end that are opposite to each other in the first direction X, and the fixing structure 200 is disposed at the head end; the fixing structure 200 includes a receiving portion and a limiting portion, the receiving portion and the base plate 1212 forming a receiving space for the head 710 to be inserted, and the two sides of the head 710 that are opposite to each other in the second direction Y are disposed in the receiving space; the battery cover 300 is connected to the limiting portion.

[0050] In other words, this application replaces the original battery bracket and battery cover with a new fixing structure 200 for fixing the battery bracket and battery cover with a snap-fit ​​structure, so that the head 710 of the circuit board 700 can be inserted into the receiving part at the head end of the battery bracket 100. This allows the two sides of the head 710 of the circuit board 700 to extend into the receiving space without being limited by the snap-fit ​​structure in the prior art, thereby freeing up the width dimension space of the head of the circuit board 700.

[0051] In other words, this application, through the new fixing structure 200 of the battery bracket 100 and the battery cover 300, allows the width of the circuit board 700 head to be appropriately increased in the width direction (in the second direction Y). The extra width on both sides of the circuit board 700 head can be inserted into the receiving space of the battery bracket 100, which effectively avoids the problem of the limited width of the circuit board 700 head caused by the existence of the snap-fit ​​structure in the prior art. It also solves the problem of insufficient width during the later glue application process and the risk of glue overflowing onto the circuit board, thereby improving work efficiency and product yield.

[0052] In addition, in the embodiments of this application, the battery cover 300 is connected to the limiting part. In a first example, the limiting part can be stacked with the receiving part in a third-order upward direction, and the limiting part is located on the side of the receiving part opposite to the bottom plate 1212 (e.g., Figure 5 and Figure 7 (As shown in the figure). In the second example, the limiting part can be arranged with the receiving part in the first direction, and the limiting part and the receiving part are aligned in the first direction (not shown in the figure). This arrangement facilitates the connection between the battery cover 300 and the limiting part, and ensures that the limiting part does not affect the installation of the head 710 of the circuit board 700, that is, it ensures that the receiving part has sufficient space for the head 710 of the circuit board 700 to be installed. The specific structural form of the receiving part of this application, as well as the specific structural form of the receiving part in the first example and the second example, will be described in detail below.

[0053] In the embodiments of this application, such as Figure 4 , Figure 5 and Figure 7 As shown, there are two fixing structures 200, both located at the head end of the base plate 1212. These two fixing structures 200 are spaced apart in the second direction Y to form a connection gap for the circuit board 700 to pass through. With this arrangement, when the head of the circuit board 700 extends into the receiving space, the two opposite sides of the head 710 in the second direction Y can be inserted into the receiving spaces of the two fixing structures 200 respectively. Furthermore, the connection gap formed between the two fixing structures 200 facilitates the wiring connection between the head of the circuit board 700 and the connector 400.

[0054] Preferably, the two fixed structures 200 are symmetrically arranged about the center line of the base plate 1212, which facilitates the processing, manufacturing, assembly and connection of the battery bracket 100 and the battery cover 300.

[0055] In the embodiments of this application, as an example, such as Figure 6 and Figure 7 As shown, the receiving portion includes a first support wall 210 and a partition wall 220. The first support wall 210 is connected to the base plate 1212 and extends along a third direction Z. The partition wall 220 is connected to the first support wall 210 and extends along a second direction Y. The first support wall 210, the partition wall 220 and the base plate 1212 are arranged to form a receiving space to receive the head 710 of the circuit board 700.

[0056] In the first example, when the limiting part and the receiving part are stacked upwards, as shown... Figure 6 and Figure 7 As shown, the limiting portion may include a second support wall 230 and a limiting wall 240. The second support wall 230 is connected to the partition wall 220 and extends along a third direction Z. The limiting wall 240 is connected to the second support wall 230 and extends along a second direction Y. The second support wall 230, partition wall 220, and limiting wall 240 are thus configured to together form an embedding space for the battery cover 300 to be inserted. The assembly method of the battery cover 300 with the embedding space will be described below.

[0057] Preferably, see continue to see Figure 6 and Figure 7 The first support wall 210 and the second support wall 230 are integral structures, and the first support wall 210 and the second support wall 230 are aligned in the third direction Z. The partition wall 220 and the limiting wall 240 have the same size in the second direction Y, that is, each fixed structure 200 is "F-shaped".

[0058] When the battery cover 300 is connected to the limiting part of the fixing structure 200, it can be assembled and connected by inserting it into the embedding space. Specifically, as shown in the figure... Figure 1 , Figure 2 , Figure 8 and Figure 9 As shown, the battery cover 300 includes a main body 310 and an insert block 320. The main body 310 includes a first end and a second end that are opposite to each other in the first direction X. The first end of the main body 310 is connected to two insert blocks 320, and the two insert blocks 320 are respectively embedded in the embedding spaces of the two fixed structures 200.

[0059] Furthermore, such as Figure 1 , Figure 2 , Figure 8 and Figure 9 As shown, the first end of the main body 310 is provided with a fitting notch, and the insert block 320 is disposed at the fitting notch, with its height lower than the surface of the main body 310. The fitting notch is adapted to the shape of the limiting wall 240. When the insert block 320 is inserted into the insertion space, the limiting wall 240 is fitted into the fitting notch, and the surface of the main body 310 is flush with the surface of the limiting wall 240. This arrangement facilitates the processing, manufacturing, and assembly of the battery bracket 100 and the battery cover 300.

[0060] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the battery holder 100 also includes a bottom wall 121 and a surrounding wall 122 disposed around the edge of the bottom wall 121. At least a portion of the surrounding wall 122 extends to the fixing structure 200 to block the side of the fixing structure 200 in the first direction X that is away from the insertion of the circuit board 700. Additionally, as... Figure 7 As shown, a raised blocking strip 130 is also provided on the head edge of the base plate 1212. The blocking strip 130 and the enclosure 122 at the position of the fixing structure 200 can limit the head 710 of the circuit board 700 and the first end of the battery cover 300.

[0061] In the embodiments of this application, such as Figure 6 As shown, the bottom wall 121 includes a first part 1211, a bottom plate 1212, and a second part 1213 connected sequentially along a first direction X. The first part 1211 and the second part 1213 are used to fix the battery cell. Specifically, as shown... Figure 1 and Figure 6 As shown, the first part 1211 and / or the second part 1213 together with the enclosure 122 form a receiving slot 120 for mounting the power supply core. The number of receiving slots 120 can be set according to requirements. Figure 1 and Figure 6The diagram illustrates that the first part 1211 and the enclosure 122 form two receiving slots 120 for installing power supply cells. However, one of the receiving slots 120 is set as a solid structure 110, without installing a power supply cell. Part of the side wall of the solid structure 110 serves as the first support wall 210 and the second support wall 230 of one of the fixed structures 200. The second part 1213 and the enclosure 122 form two receiving slots 120 for installing power supply cells, and both receiving slots 120 are used to install power supply cells.

[0062] In the embodiments of this application, such as Figure 4 and Figure 6 As shown, the battery bracket 100 also includes two tail-end latching structures 500 and two middle-end latching structures 600 disposed on the base plate 1212. The two middle-end latching structures 600 are disposed in the middle of the base plate 1212, and the two tail-end latching structures 500 are disposed at the tail end of the base plate 1212 and are spaced apart in the second direction Y. The tail end of the circuit board 700 is limited to the two tail-end latching structures 500.

[0063] like Figure 9 As shown, the main body 310 is provided with multiple latches 330, which respectively latch with the tail latching structure 500 and the middle latching structure 600. Preferably, the fixing structure 200, the middle latching structure 600, and the tail latching structure 500 located on the same side of the circuit board 700 are aligned in the first direction X. Figure 2 As shown, when the battery cover 300 is assembled with the fixing structure 200 of the battery bracket 100, the first end of the battery cover 300 can be embedded into the two fixing structures 200 first, and then it can be clamped with the tail clamping structure 500 and the middle clamping structure 600 through the claw 330.

[0064] In the embodiments of this application, such as Figure 4 and Figure 5 As shown, the circuit board 700 includes a middle portion 720 extending along a first direction X and a head 710 and a tail portion disposed at both ends of the middle portion 720. The size of the middle portion 720 in the second direction Y is smaller than the size of the head 710 in the second direction Y. The middle snap-fit ​​structure 600 and the tail snap-fit ​​structure 500 are both disposed between the edges of the middle portion 720 and the base plate 1212.

[0065] With this design, based on the existing middle section 720 of the board, the width of the head 710 of the middle section 720 is appropriately increased in the width direction (second direction). The extra width on both sides of the head 710 can be inserted into the receiving space of the battery bracket, solving the problem of insufficient width during subsequent glue application and the risk of glue overflowing onto the circuit board. It also facilitates the installation of the middle snap-fit ​​structure 600 and the tail snap-fit ​​structure 500, making it easier for the battery cover 300 to connect with them.

[0066] In the second example, when the limiting part and the receiving part are arranged in the first direction X and aligned in the first direction X, the limiting part can be located between the center of the plate 720 and the edge of the bottom plate 1212. The structure of the limiting part can be similar to the middle snap-fit ​​structure 600 and the tail snap-fit ​​structure 500 (not shown in the figure).

[0067] According to a second aspect of this application, a battery is provided, including the battery mounting structure, cell, and circuit board 700 as described above.

[0068] According to a third aspect of this application, a laptop computer is provided, which includes the battery as described above.

[0069] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them. The protection scope of this application is not limited thereto. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any person skilled in the art can still modify or easily conceive of changes to the technical solutions described in the foregoing embodiments within the scope of the technology disclosed in this application, or make equivalent substitutions for some of the technical features.
