Description

Technical Field

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

[0002] The battery is a crucial component of a laptop, determining not only its portability and battery life but also directly impacting user experience and device performance. Within a laptop battery, the battery holder not only defines its dimensions but also protects the internal battery cells and circuit boards; therefore, the battery holder is extremely important for laptop batteries.

[0003] As laptops become thinner and lighter, batteries and battery holders also become thinner and lighter. This reduces the structural strength of the battery holder, resulting in louder noises from the battery when it is subjected to external impacts (such as when a user presses on the laptop).

[0004] To reduce battery noise, existing batteries are generally equipped with cross-shaped or mountain-shaped support ribs. However, these two types of support ribs have limited effect on improving the structural strength of the battery bracket, and the battery noise is still relatively large. Utility Model Content

[0005] In view of this, this application provides a battery bracket and a battery to solve the problem of insufficient structural strength of the battery bracket and excessive noise when the battery is subjected to external impact.

[0006] According to one aspect of this application, a battery holder is provided, the battery holder including a frame, a support member and a support assembly, the support member being connected to the inner sidewall of the frame, and the support assembly being arranged on the support member to form a plurality of chambers, each chamber being continuously surrounded by the support assembly.

[0007] Preferably, the support assembly includes a first support member, a second support member, and a first connector. The first support member, the second support member, and the first connector are all fixed to the support member. The first support member is connected end to end, and the second support member is connected end to end. The second support member is located inside the first support member. One end of the first connector is connected to the inner wall of the first support member, and the other end of the first connector is connected to the outer wall of the second support member.

[0008] Preferably, the support assembly further includes a second connector, which is fixed to the support member, and both ends of the second connector are respectively connected to the inner sidewall of the second support member.

[0009] Preferably, the first support member includes a main body and a first support, the first support being connected end to end, and the main body including multiple discontinuous parts, with any two adjacent parts connected to the outer side wall of the same first support.

[0010] Preferably, the battery bracket further includes a connector, which is fixed to the support member, and both ends of the connector are respectively connected to the outer side wall of the first support member and the inner side wall of the frame.

[0011] Preferably, the support member is perpendicular to the first direction, and the support assembly is divided into at least two parts, wherein the dimension of one part in the first direction is greater than the dimension of the other part in the first direction.

[0012] Preferably, the support includes two reference planes that are opposite to each other in the first direction, and the support assembly is arranged on one of the reference planes;

[0013] The support member has a clearance groove, which is recessed from the reference surface where the support component is located toward the interior of the support member.

[0014] According to another aspect of this application, a battery is provided, the battery including the battery holder described above.

[0015] Preferably, the battery further includes a battery protection board and a battery cell, both of which are located within the frame, and a portion of the support assembly supports the battery protection board.

[0016] Preferably, the battery further includes a cover plate, which covers the side of the battery protection plate opposite to the support member.

[0017] In the battery holder of this application, support components are arranged on the support member to form multiple chambers, each chamber being continuously enclosed by the support components. Thus, the support components consist of multiple closed structures, giving them higher structural strength, which in turn results in higher overall structural strength for the support member and the support components. This improved structural strength of the battery holder reduces abnormal noise generated when the battery is subjected to external impact. Attached Figure Description

Detailed Implementation

[0025] 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.

[0026] 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.

[0027] 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.

[0028] As used herein, the term “and / or” includes any one of the relevant items listed and any combination of any two or more items.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] The following will combine Figures 1 to 5 The battery holder 1 and the battery are described below. Figures 1 to 5 In the diagram, the first direction L1 intersects with the second direction L2, and the third direction L3 intersects with the plane defined by the first direction L1 and the second direction L2. Preferably, the intersection is perpendicular. The following description will use the example of the first direction L1, the second direction L2 and the third direction L3 being perpendicular to each other to describe the battery holder 1 and the battery.

[0035] According to one aspect of this application, a battery holder 1 is provided, as shown in the figure. Figure 3 As shown, the battery holder 1 includes a frame 11, a support member 13, and a support assembly 12. The support member 13 is connected to the inner wall of the frame 11, and the support assembly 12 is arranged on the support member 13 to form multiple chambers, each chamber being continuously enclosed by the support assembly 12. Thus, the support assembly consists of multiple closed structures, giving it higher structural strength, which in turn results in higher overall structural strength for the support member and the support assembly. This improved structural strength of the battery holder reduces abnormal noise generated when the battery is subjected to external impact.

[0036] Preferably, the entire battery bracket 1 is integrally formed.

[0037] In the embodiments of this application, such as Figure 1 and Figure 3As shown, the two ends of the support member 13 in the second direction L2 are connected to the inner sidewalls of the frame 11, and the support member 13 divides the internal space of the frame 11 into two mounting cavities 14. The two mounting cavities 14 are located on both sides of the support member 13 in the third direction L3, and both mounting cavities 14 can be used to install the battery cell 3. The support member 13 includes two reference surfaces 132 that are opposite to each other in the first direction L1. The support assembly 12 is arranged on one reference surface 132, and the other reference surface 132 is flush with the surface of the frame 11 opposite to the support assembly 12 in the first direction L1.

[0038] In addition, the support member 13 is provided with a clearance groove 131. The clearance groove 131 is recessed from the reference surface 132 where the support component 12 is located along the first direction L1 toward the interior of the support member 13. The setting of the clearance groove 131 can reduce the weight of the battery bracket 1 and meet the lightweight requirements of the battery.

[0039] like Figure 2 and Figure 3 As shown, the support assembly 12 includes a first support member 121, a second support member 122, and a first connector 123. The first support member 121, the second support member 122, and the first connector 123 are all fixed to the support member 13. The first support member 121 is connected end-to-end to form a closed chamber, and the second support member 122 is connected end-to-end to form another closed chamber. Compared to support ribs in a cross or mountain shape, the closed first support member 121 and the second support member 122 have higher structural strength, resulting in higher overall structural strength for the support assembly 12 and the support member 13. Thus, the structural strength of the battery bracket 1 is improved, thereby reducing abnormal noise generated when the battery is subjected to external impact.

[0040] Optionally, the first support member 121 encloses a rectangular parallelepiped-shaped closed cavity, and the second support member 122 also encloses a rectangular parallelepiped-shaped closed cavity.

[0041] Furthermore, the first support member 121 includes a main body 1212 and a support portion 1211. The support portion 1211 is connected end to end, and the main body 1212 includes multiple discontinuous parts. Any two adjacent parts are connected to the outer side wall of the same support portion 1211. The support portion 1211 itself is a closed structure, and the main body 1212 and the support portion 1211 together form another closed structure. In this case, the support assembly 12 has more closed structures, which makes the support assembly 12 have higher structural strength.

[0042] In addition, the support part 1211 is used to support the contact piece 22 in the battery protection board 2. Compared with the strip structure, the support part 1211 connected end to end has higher support strength and can improve the stability of the support for the battery protection board 2.

[0043] Alternatively, the first support member 121 may also include only the main body 1212, in which case the main body 1212 is strip-shaped and connected end to end to form a closed structure.

[0044] Furthermore, such as Figure 2 and Figure 3 As shown, the second support member 122 is located inside the first support member 121, that is, the second support member 122 is located within the closed cavity enclosed by the first support member 121. The first connecting member 123 is strip-shaped, with one end connected to the inner wall of the first support member 121 and the other end connected to the outer wall of the second support member 122. There can be one or more first connecting members 123, thereby dividing the space between the first support member 121 and the second support member 122 into multiple closed cavities. The first support member 121, the second support member 122, and the multiple first connecting members 123 cooperate to give the support assembly 12 higher structural strength.

[0045] Optionally, the plurality of first connectors 123 are divided into two categories, one of which is a strip structure extending along the second direction L2, and the other is a strip structure extending along the third direction L3.

[0046] It should be noted that the forms of the first support member 121, the second support member 122, and the first connector 123 are not limited to those of other types. Figures 1 to 3 As shown in the diagram, for example, the first support member 121 and the second support member 122 can enclose a cylindrical closed cavity, and the first connector 123 can extend in any direction, provided that its two ends are connected to the inner sidewall of the first support member 121 and the outer sidewall of the second support member 122, respectively.

[0047] Furthermore, the support assembly 12 also includes a second connector 124, which is strip-shaped and fixed to the support member 13. Both ends of the second connector 124 are connected to the inner sidewall of the second support member 122, thereby dividing the closed cavity enclosed by the second support member 122 into more cavities. The second connector 124 can further improve the structural strength of the support assembly 12, thereby giving the battery bracket 1 a higher structural strength.

[0048] Optionally, the second connector 124 can extend in any direction, and different second connectors 124 can be parallel or intersecting. Preferably, there are three second connectors 124, and all three second connectors 124 extend along a third direction L3.

[0049] Furthermore, the support assembly 12 may also include a third connector (not shown in the figure), which is fixed to the support member 13, and both ends of the third connector are connected to the inner sidewall of the first support member 121. The third connector can further divide the space between the first support member 121 and the second support member 122 into more closed chambers, thus giving the support assembly 12 more closed structures and thereby higher structural strength. Optionally, the third connector can extend in any direction, and different third connectors can be parallel or intersecting.

[0050] like Figure 2 As shown, the support member 13 is provided with two stabilizing members 16, which are connected to the inner wall of the frame 11. The two stabilizing members 16 are located on both sides of the support member 13 in the second direction L2. The battery bracket 1 also includes two connecting members 15, which are fixed to the support member 13. For any one connecting member 15, one end of the connecting member 15 is connected to the outer wall of the first support member 121, and the other end is connected to the inner wall of the frame 11. In this way, the connection between the support assembly 12 and the frame 11 is realized through the connecting members 15, so that the entire battery bracket 1 has higher structural strength.

[0051] Optionally, the support assembly 12 is divided into at least two parts, one part having a larger dimension in the first direction L1 than the other part in the first direction L1. In other words, the support assembly 12 has at least two parts with different dimensions in the third direction L3. The larger part in the third direction L3 is used to support the plate body 21 of the battery protection board 2, and the smaller part in the third direction L3 can be used to support the contact piece 22 of the battery protection board 2. In the battery with the above-described battery bracket 1, the battery protection board 2 is covered with a cover plate 4, and the plate body 21 and the contact piece 22 are supported by different structures, so that the support assembly 12 can support the battery protection board 2 more stably, thereby reducing the abnormal noise generated by the mutual compression of the battery bracket 1, cover plate 4, and battery protection board 2 when the battery bracket 1 and cover plate 4 undergo elastic deformation.

[0052] by Figures 1 to 3Taking the support assembly 12 as an example, the second support member 122 and the second connector 124 are used to support the plate body 21, and the support portion 1211 is used to support the bumper 22. The dimension of the second support member 122 in the first direction L1 is equal to the dimension of the second connector 124 in the first direction L1, and the dimension of the second support member 122 in the first direction L1 is greater than the dimension of the support portion 1211 in the second direction L2. The dimensions of other structures in the support assembly 12 in the first direction L1 can be equal to the dimensions of the support portion 1211 in the first direction L1, or the dimensions of other structures in the support assembly 12 in the first direction L1 can be any dimension less than or equal to the dimension of the second support member 122 in the first direction L1.

[0053] According to another aspect of this application, a battery is provided, such as... Figure 4 and Figure 5 As shown, the battery includes the battery holder 1 described above, which has the same technical effects as the battery holder 1 described above, and will not be described again here.

[0054] Furthermore, such as Figure 5 As shown, the battery also includes a battery protection board 2 and battery cells 3. The battery protection board 2 includes contact plates 22 and a board body 21. Contact plates 22 are arranged on both sides of the board body 21 in the first direction L1. Each mounting cavity 14 of the battery bracket 1 can be equipped with two battery cells 3. The two battery cells 3 are stacked, with the upper battery cell 3 connected to the contact plate 22 located above the board body 21, and the lower battery cell 3 connected to the contact plate 22 located below the board body 21. The second support member 122 and the second connector 124 support the lower surface of the board body 21, and the support part 1211 supports the lower contact plate 22.

[0055] like Figure 4 As shown, the battery also includes a cover plate 4, which covers the side of the battery protection plate 2 facing away from the support assembly 12, thereby protecting the battery protection plate 2.

[0056] In addition, the battery also includes a first wrapping film 5 and a second wrapping film 6. The first wrapping film 5 and the second wrapping film 6 respectively wrap the battery bracket 1 and the battery cell 3 from both sides in the first direction L1, thereby fixing the battery bracket 1, the battery protection board 2, the battery cell 3 and the cover plate 4 into a whole. The first wrapping film 5 and the second wrapping film 6 can be fixed by adhesive bonding.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
