Detailed Implementation

[0045] 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. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0046] 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.

[0047] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0048] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed during use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0049] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0050] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0051] The following describes in detail the overall structure, working principle, and technical effects of the battery holder 010 and mobile electronic device provided by this utility model through embodiments and in conjunction with the accompanying drawings.

[0052] In related technologies, the components that account for the largest proportion of weight in a laptop are the battery and the battery bracket 010. Therefore, the issue of lightweighting the battery bracket 010 has always been a research direction in laptop design. Whether from the perspective of user experience or environmental protection, reducing the weight of the battery bracket 010 is necessary.

[0053] However, the battery bracket 010 needs to withstand vibrations from handling, drops, or equipment operation. Therefore, excessive weight reduction of the battery bracket 010 may cause deformation of the battery bracket 010, thereby affecting the stability of battery fixation and even causing safety hazards.

[0054] Therefore, this application utilizes the "dual-mode skull" of a woodpecker to biomimeticly design the battery holder 010. One side of the woodpecker's skull is thicker and stronger, bearing the main impact and preventing skull fracture; the other side of the woodpecker's skull is thinner and tougher, with more muscles attached, absorbing impact force through elastic deformation and converting some of the impact into energy dissipation through neck muscle stretching. This application applies the mechanical advantages of this "asymmetrical structure" to the product design, achieving weight reduction in the battery holder 010 while obtaining stronger shock absorption, thereby enhancing product competitiveness and ultimately increasing corporate profits.

[0055] Please refer to Figure 1 The battery holder 010 provided by this utility model is used in mobile electronic devices.

[0056] Among them, the mobile electronic device can be a laptop computer.

[0057] The battery provided by this utility model includes a battery bracket 010 and a battery cell, with the battery cell disposed in the accommodating cavity 101 and connected to the battery bracket 010.

[0058] Please refer to Figure 1 This utility model provides a battery holder 010, including a holder body 100, the holder body 100 having an accommodating cavity 101 for accommodating battery cells, the holder body 100 being divided into a first region 103 and a second region 104 by a first axis 102, the first axis 102 passing through the center of the accommodating cavity 101; the inner sidewall of the holder body 100 located in the first region 103 is connected to the inner sidewall of the holder body 100 located in the second region 104 and forms the accommodating cavity 101;

[0059] An energy-absorbing part 200 is provided on the inner wall of the support body 100 located in the first region 103;

[0060] The energy-absorbing part 200 includes a groove.

[0061] Understandably, on the one hand, the inner wall of the support body 100 located in the first region 103 is designed to reduce the amount of adhesive used, so as to form an energy-absorbing part 200 including a groove, thereby achieving weight reduction of the support.

[0062] On the other hand, by providing an energy-absorbing part 200 on the inner wall of the bracket body 100 located in the first region 103, and not providing an energy-absorbing part 200 on the inner wall of the bracket body 100 located in the second region 104, the battery bracket 010 forms an asymmetrical structure. The energy-absorbing part 200 includes a groove, so the bracket body 100 with the energy-absorbing part 200 is thinner and more elastic. When the battery bracket 010 is impacted, the bracket body 100 located in the second region 104 can withstand the main impact and prevent structural breakage, while the bracket body 100 located in the first region 103 transmits the force to the more elastic energy-absorbing part 200, forming a buffer and absorption of the force, thereby eliminating the damage of the impact force to the structure and improving the protective properties of the battery bracket 010. Therefore, through the above design, this application reduces the structural weight of the battery bracket 010 and improves its shock absorption effect by using an asymmetrical design and a reduced adhesive design, thereby optimizing the two major issues of weight reduction and shock absorption of the battery bracket 010.

[0063] In this embodiment, please refer to Figure 1 and Figure 7 The battery bracket 010 also includes a base 400, which is disposed at the bottom of the bracket body 100 along the third direction Z and extends along the inner sidewall of the bracket body 100 toward the receiving cavity 101.

[0064] Understandably, the base support 400 is used to support the battery cells located in the cavity 101, making the battery structure more stable, while optimizing the gap between the battery cells and the frame, reducing the risk of abnormal noise.

[0065] In this embodiment, please refer to Figure 2 and Figure 6 The energy-absorbing part 200 also includes an elastic energy-absorbing member 300, which is disposed in the groove and connected to the battery bracket 010. When the battery bracket 010 is impacted, the elastic energy-absorbing member 300 is used to absorb the impact force.

[0066] Optionally, the elastic energy-absorbing element 300 is bonded to the bottom wall 211 of the groove of the battery holder 010.

[0067] Optionally, the elastic energy-absorbing component 300 can be made of lightweight elastic materials such as foam plastic or foam rubber.

[0068] Understandably, on the one hand, based on the woodpecker's "dual-mode skull," one side of the woodpecker's skull is thicker and stronger, bearing the main impact and preventing skull fracture; the other side of the woodpecker's skull is thinner and tougher, with more muscles attached, absorbing impact force through elastic deformation and converting some of the impact into energy dissipation through neck muscle stretching. The elastic energy-absorbing component 300 can simulate "muscle" to absorb the impact force on the support body 100. On the other hand, the elastic energy-absorbing component 300 can be made of a lightweight elastic material with heat dissipation properties, thus optimizing the battery's heat dissipation characteristics.

[0069] In this embodiment, the energy-absorbing portion 200 includes a groove. It is understood that by reducing the amount of adhesive used on the inner wall of the support body 100 located in the first region 103, multiple energy-absorbing portions 200, each including at least one groove, are formed, thereby achieving weight reduction of the support. Simultaneously, the support body 100 with the energy-absorbing portion 200 is thinner and more elastic, capable of dispersing stress. Furthermore, the support body 100 configured in this application can reduce weight by 15%-20% compared to the prior art.

[0070] In one embodiment, please refer to Figures 1-7 The energy-absorbing part 200 includes multiple grooves, which form a honeycomb structure. The honeycomb structure formed by the multiple grooves helps to prevent stress accumulation.

[0071] In one embodiment, please refer to Figure 4 The energy-absorbing part 200 includes a groove 210; the groove 210 has a bottom wall 211, a first side wall 212 and a second side wall 213. The first side wall 212 and the second side wall 213 are located on opposite sides of the bottom wall 211, one end of the first side wall 212 is connected to the bottom wall 211 and the other end is connected to the inner side wall of the support body 100, and one end of the second side wall 213 is connected to the bottom wall 211 and the other end is connected to the inner side wall of the support body 100.

[0072] Understandably, on the one hand, by reducing the amount of adhesive on the inner wall of the bracket body 100 located in the first region 103, an energy-absorbing part 200 with at least one groove 210 is formed, thereby reducing the weight of the bracket; on the other hand, the bracket body 100 with the groove 210 is thinner and more elastic. When the battery bracket 010 is impacted, the bracket body 100 located in the second region 104 can withstand the main impact to prevent structural breakage, while the bracket body 100 located in the first region 103 transmits the force to the bracket body 100 at the more elastic groove, thereby forming a buffer and absorption of the force, thereby eliminating the damage of the impact force to the structure, and improving the protective properties of the battery bracket 010.

[0073] Alternatively, please refer to Figure 4 The first sidewall 212 is inclined, and the extension lines of the first sidewall 212 and the bottom wall 211 are set at a first angle 214.

[0074] Among them, the first included angle 214 is less than or equal to 30°.

[0075] Alternatively, please refer to Figure 4 The second side wall 213 is inclined and the extension line of the second side wall 213 and the bottom wall 211 are set at a second angle 215.

[0076] The second included angle 215 is less than or equal to 30°.

[0077] It is understandable that by setting the first sidewall 212 and the second sidewall 213 of the groove 210 to be inclined relative to the inner sidewall of the bracket body 100, the groove 210 transitions through the inclined surface; when the battery bracket 010 is impacted, the inner sidewall of the bracket body 100 causes the stress to be smoothly transferred to the bracket body 100 at the bottom wall 211 along the inclined first sidewall 212 and the second sidewall 213. This setting disperses the stress, making the bracket body 100 with the groove 210 less prone to breakage.

[0078] In some alternative embodiments, the groove 210 can be an arc-shaped structure, a circular structure, or other structures, which can also disperse stress.

[0079] In this embodiment, please refer to Figure 4 The thickness of the support body 100 is T, that is, the thickness of the first frame 120, the second frame 130, the third frame 140 and the fourth frame 150 are all T. Among them, the thickness of the energy-absorbing part 200 ranges from 0.47T to 0.5T.

[0080] Optionally, the thickness of the support body 100 is typically 1.5mm-2.0mm, and the thickness of the support body 100 with the energy-absorbing part 200 is 0.8mm-1.0mm.

[0081] Understandably, this design meets the fire safety standards of the battery bracket 010 while retaining its basic rigidity and flexibility.

[0082] It is worth mentioning that the battery bracket 010 body can achieve a density gradient distribution through 3D printing technology. Using 3D printing technology, materials with different densities and mechanical properties are used in the bracket body 100 located in the first region 103 and the second region 104, respectively; among them, the bracket body 100 located in the second region 104 is 3D printed with a high-density material, mainly to withstand impact; while the bracket body 100 located in the first region 103 is 3D printed with a highly elastic material, mainly to absorb kinetic energy and dampen vibration.

[0083] In this embodiment, the battery holder 010 has a first direction X, a second direction Y, and a third direction Z that are perpendicular to each other.

[0084] In this embodiment, please refer to Figures 1-7 The support body 100 includes a first frame 120, a second frame 130, a third frame 140 and a fourth frame 150. The first frame 120, the second frame 130, the third frame 140 and the fourth frame 150 form an accommodating cavity 101. The first frame 120 and the third frame 140 are arranged along the second direction Y and are arranged opposite to each other. The second frame 130 and the fourth frame 150 are arranged along the first direction X and are arranged opposite to each other.

[0085] Understandably, the battery can be housed within the accommodating cavity 101, and the aforementioned support body 100 is highly stable, providing the battery with primary protection and shape.

[0086] In one embodiment, please refer to Figures 1-5 The first axis 102 is set along the first direction X, and the first axis 102 passes through the center point of the first frame 120, the center point of the accommodating cavity 101 and the center point of the third frame 140; part of the first frame 120, the second frame 130 and part of the third frame 140 are located in the first region 103 and are provided with a plurality of spaced energy absorbing parts 200; another part of the first frame 120, the fourth frame 150 and part of the third frame 140 are located in the second region 104.

[0087] In one embodiment, please refer to Figure 7 The first axis 102 is set along the second direction Y, and the first axis 102 passes through the center point of the second frame 130, the center point of the accommodating cavity 101 and the center point of the fourth frame 150; the first frame 120, part of the second frame 130 and part of the fourth frame 150 are located in the first region 103 and are provided with a plurality of spaced energy absorbing parts 200; another part of the second frame 130, the third frame 140 and another part of the fourth frame 150 are located in the second region 104.

[0088] It is understood that the above two embodiments propose two implementation methods for dividing the bracket body 100 into a first region 103 and a second region 104. Specifically, the first axis 102 positioned along the second direction Y achieves a greater center offset effect compared to the first axis 102 positioned along the first direction X. Therefore, in actual production, the emphasizing direction of the first region 103 and the second region 104 can be selected according to the actual situation of the battery bracket 010.

[0089] In this embodiment, please refer to Figure 3 The first frame 120, the second frame 130, the third frame 140, and the fourth frame 150 are connected in sequence and form multiple corners 180; please refer to... Figure 6 The two ends of the first frame 120 form an angle 180 with the second frame 130 and the fourth frame 150, and the two ends of the third frame 140 form an angle 180 with the second frame 130 and the fourth frame 150.

[0090] It is worth mentioning that the thin and tough energy-absorbing part 200 formed after the glue reduction design between the batteries should avoid the corners 180 that are prone to impact, so as to ensure that the corner 180 can provide a reference and support for the positioning of the bracket body 100, while having sufficient strength to withstand direct impact without damage; therefore, the distance between the energy-absorbing part 200 and any corner 180 is greater than or equal to 5mm.

[0091] In this embodiment, please refer to Figures 1-3 and Figures 5-7 The outer side wall of the support body 100 is also provided with a plurality of spaced first connecting parts 110. Among them, the outer side walls of the first frame 120, the second frame 130, the third frame 140 and the fourth frame 150 are all provided with first connecting parts 110.

[0092] Optionally, the first connecting part 110 can be a locking lug structure for fixing to other structures.

[0093] It is worth mentioning that the thin and tough energy-absorbing part 200 formed after the glue reduction design between the batteries should avoid the first connecting part 110 which is susceptible to impact, so as to ensure that the protruding part of the first connecting part 110 can provide a reference and support for the positioning of the bracket body 100, while having sufficient strength to withstand direct impact without damage; therefore, the distance between the energy-absorbing part 200 and any first connecting part 110 is greater than or equal to 5mm.

[0094] In this embodiment, please refer to Figures 1-5The bracket body 100 also includes a mounting part 160, which is used to mount the PCM board. The PCM board is electrically connected to the battery cell. One end of the mounting part 160 is connected to the second frame 130, and the other end is connected to the fourth frame 150.

[0095] Understandably, the mounting section 160 is used to support and protect the PCM board, and can also play a certain role in ESD anti-interference.

[0096] In this embodiment, the mounting part 160 is provided with a plurality of second connecting parts 170 for limiting the PCM plate. Some of the second connecting parts 170 are connected to the inner sidewall of the second frame 130, and some of the second connecting parts 170 are connected to the inner sidewall of the fourth frame 150. The second connecting parts 170 are used to limit the installation of the PCM plate, and the second connecting parts 170 can be rib structures.

[0097] It is worth mentioning that the thin and tough energy-absorbing part 200 formed after the glue reduction design between the batteries should avoid the second connecting part 170 which is susceptible to impact, so as to ensure that the protruding part of the second connecting part 170 can provide a reference and support for the positioning of the battery while having sufficient strength to withstand direct impact without damage; therefore, the distance between the energy-absorbing part 200 and any second connecting part 170 is greater than or equal to 5mm.

[0098] The working principle and process of the battery holder 010 and mobile electronic device provided in this embodiment of the utility model are as follows:

[0099] When the battery bracket 010 is impacted, due to the weight shift, the bracket body 100 located in the second region 104 has a higher probability of bearing the main impact; the bracket body 100 located in the second region 104 transfers the stress to the bracket body 100 located in the first region 103, and the bracket body 100 located in the first region 103 transfers the stress along the inclined first sidewall 212 and second sidewall 213 to the bracket body 100 located in the energy absorption part 200. The groove forms a buffer against the force, and the elastic energy absorption member 300 absorbs the force, thereby eliminating the damage of the impact force to the structure.

[0100] In summary, the battery holder 010 and mobile electronic device provided by this utility model embodiment, on the one hand, reduce the adhesive content of the inner wall of the holder body 100 located in the first region 103, forming multiple energy-absorbing parts 200 including grooves, thereby achieving weight reduction of the holder; on the other hand, by providing multiple energy-absorbing parts 200 on the inner wall of the holder body 100 located in the first region 103, and not providing energy-absorbing parts 200 on the inner wall of the holder body 100 located in the second region 104, the battery holder 010 forms an asymmetrical structure; In this design, the energy-absorbing part 200 includes a groove, thus the bracket body 100 with the energy-absorbing part 200 is thinner and more elastic. When the battery bracket 010 is impacted, due to the weight shift, the bracket body 100 located in the second region 104 has a higher probability of absorbing the main impact, preventing structural breakage. Simultaneously, the bracket body 100 located in the first region 103 transmits the force to the more elastic energy-absorbing part 200, forming a buffer and absorption of the force, thereby mitigating the impact damage to the structure and enhancing the protective properties of the battery bracket 010. Therefore, through the above design, this application, by implementing an asymmetrical design and reducing the amount of adhesive used in the battery bracket 010, reduces the structural weight of the battery bracket 010 while improving its shock absorption effect, thus optimizing the two major issues of weight reduction and shock absorption in the battery bracket 010.

[0101] Furthermore, by incorporating an energy-absorbing elastic element, the elastic energy-absorbing element 300 can absorb the impact force on the support body 100. Simultaneously, the elastic energy-absorbing element 300 can be made of a lightweight elastic material with heat-dissipating properties, thus optimizing the battery's heat dissipation characteristics.

[0102] Furthermore, by tilting the first sidewall 212 and the second sidewall 213 of the groove 210 relative to the inner sidewall of the bracket body 100, when the battery bracket 010 is impacted, the stress on the inner sidewall of the bracket body 100 is transmitted to the bracket body 100 at the bottom wall 211 via the tilted first sidewall 212 and the second sidewall 213. This arrangement makes it less likely for the energy-absorbing part 200 of the bracket body 100 to break.

[0103] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
