[0029] As a preface to the embodiments of this application, lightweight laptop battery design is a core competitive advantage, given the same capacity and power. Currently, the cell weight of a laptop battery accounts for approximately 90% of the total battery weight, the frame weight accounts for approximately 6%, and the remaining weight is made up of other components. With the improvement of battery design and the increasing demand for laptops, customer demand for lightweight batteries has also gradually increased. How to ensure structural strength while minimizing weight has become a research and development direction for mechanical engineering (ME).
[0030] In view of this, an embodiment of the present application provides a battery plastic frame, aiming to solve the above technical problems.
[0031] See also Figures 1 to 2 As shown, a battery plastic frame in an embodiment of the present application includes a frame body 1 and a supporting plate 2, the supporting plate 2 is located in the frame body 1 and is connected to the frame body 1; the supporting plate 2 includes a main body 21 and a rib structure 22, the main body 21 has a receiving groove 210, the rib structure 22 is arranged in the receiving groove 210 and is connected to the main body 21, and the rib structure 22 includes: a first rib 221 and a plurality of second ribs 222, the plurality of second ribs 222 surround the first rib 221 and are arranged at intervals from each other, and the second ribs 222 are connected to the first rib 221. It should be understood that the supporting plate 2 and the frame body 1 together form a receiving area for receiving and protecting single cells. The supporting plate 2 is usually provided with a slot, a fixing point or other design to install a protection circuit board for controlling and managing the charging and discharging of single cells and communicating with other electronic devices. The support plate 2 is lightweight by providing a receiving groove 210 within its main body 21. Furthermore, a lightweight rib structure 22 is provided within the receiving groove 210, connecting the weak areas formed by the grooves in the main body 21 to reduce the impact on the strength of the support plate 2. The topological structure formed by the first rib 221 and multiple second ribs 222 provides effective support within the receiving groove 210, resulting in a high-strength and aesthetically pleasing structure that can meet the load-bearing requirements of individual batteries.
[0032] In some embodiments, see Figure 3As shown, the receiving groove 210 has two opposing first side walls 211 and two second side walls 212. The first side wall 211 is connected to the second side wall 212 and encloses the receiving groove 210. The second rib 222 includes a first section 2221, a second section 2222, and a third section 2223. The first section 2221 is connected to the first rib 221, the second section 2222 is connected to the first section 2221 and extends away from the first rib 221 and is connected to the first side wall 211. The third section 2223 is connected to the first section 2221 and extends away from the first rib 221 and is connected to the second side wall 212. The second rib 222 adopts a three-section structure to connect the main body 21 and the first rib 221, further enhancing the stability and support strength of the rib structure 22. More specifically, the second rib 222 adopts a Y-shaped fork structure, and the two ends of the fork are respectively connected to the first side wall 211 and the second side wall 212. The force of the first rib 221 is dispersed to the second section 2222 and the third section 2223 through the first section 2221, and the second section 2222 and the third section 2223 are distributed at a certain angle and are respectively connected to the first side wall 211 and the second side wall 212 of the accommodating groove 210, thereby reducing the stretching of the second rib 222 on the main body 21 and further improving the supporting capacity of the rib structure 22.
[0033] In some embodiments, see Figure 2 and Figure 4 As shown, the first rib 221 has a receiving groove 220, and the rib structure 22 also includes a third rib 223. The third rib 223 is disposed in the receiving groove 220 and connected to the first rib 221. By providing the receiving groove 220 on the first rib 221, the weight of the first rib 221 can be reduced. By disposing the third rib 223 in the receiving groove 220 to connect the first rib 221, the third rib 223 can be a cross-shaped structure to divide the receiving groove 220 into several grids to increase the strength and support capacity of the first rib 221. In some embodiments, the third rib 223 can be a topological structure and have multiple connection fulcrums to connect to the first rib 221, further ensuring the strength and support capacity of the rib structure 22.
[0034] In some embodiments, see Figure 2 、 Figure 4 and Figure 5As shown, the rib structure 22 also includes a plurality of fourth ribs 224 disposed within the receiving groove 210 and connected to the main body 21. At least one fourth rib 224 is disposed between two adjacent second ribs 222. The fourth ribs 224 enhance the strength of the main body 21 between adjacent second ribs 222, preventing deformation of the main body 21 under the tension of the second ribs 222, which would otherwise reduce the overall structural strength of the support plate 2. The provision of multiple fourth ribs 224 not only increases the structural strength of the main body 21 but also forms support surfaces in the blank areas between adjacent second ribs 222, thereby increasing the load-bearing contact area of the rib structure 22, further reducing the load-bearing pressure of the rib structure 22 and improving its load-bearing capacity.
[0035] In some embodiments, see Figure 4 As shown, the fourth rib 224 has a first end 2241 and a second end 2242 opposite to each other. The first end 2241 is connected to the first side wall 211 of the receiving groove 210, and the second end 2242 is connected to the second side wall 212 of the receiving groove 210. It should be understood that by connecting the adjacent first side wall 211 and second side wall 212 of the receiving groove 210 via the fourth rib 224, the fourth rib 224 can, on the one hand, provide support for the adjacent first side wall 211 and second side wall 212, thereby preventing stress concentration at the junction of the first side wall 211 and the second side wall 212 under the tension of the rib structure 22, thereby causing deformation of the receiving groove 210 and affecting the support and structural strength of the rib structure 22. On the other hand, the fourth rib 224 connects the first side wall 211 and the second side wall 212 respectively, and can be arched toward the direction of the first rib 221 to form a larger bearing surface in the blank area between adjacent second ribs 222, so as to increase the bearing contact area of the rib structure 22, fill the problem of insufficient support in the blank area, further reduce the bearing pressure of the rib structure 22, and improve the bearing capacity.
[0036] In some embodiments, see Figure 2 As shown, the rib structure 22 also includes a fifth rib 225, which is located between and connects the fourth rib 224 and the first rib 221. The fifth rib 225 connects the fourth rib 224 and the first rib 221 to form a monolithic structure, thereby increasing the structural strength of the first rib 221 and ensuring the support of the rib structure 22. In some embodiments, the first rib 221 has a receiving groove 220. The fifth rib 225 connects the fourth rib 224 and the first rib 221 to avoid the risk of insufficient overall support, deformation, or breakage caused by the first rib 221 having the receiving groove 220.
[0037] In some embodiments, see Figure 4As shown, the receiving groove 210 has a bottom wall 213, which is used to enclose the receiving groove 210. The first rib 221 and the second rib 222 are both connected to the bottom wall 213. On the one hand, the bottom wall 213 can serve as a fire barrier to improve the fire resistance of the battery plastic frame and increase safety. On the other hand, the bottom wall 213 can also serve as a connecting structure, connecting the main body 21 and the rib structure 22, further increasing the stability of the connection between the rib structure 22 and the main body 21.
[0038] In some embodiments, see Figure 5 and Figure 6 As shown, the bottom wall 213 is provided with a through hole 214, which is connected to the receiving groove 210. On the one hand, by providing the through hole 214 on the bottom wall 213, the heat dissipation performance of the support plate 2 can be improved. On the other hand, the design of the through hole 214 can increase the weight reduction effect of the support plate 2, and at the same time, the support plate 2 as a whole has better elastic deformation ability.
[0039] In some embodiments, the main body 21 and the rib structure 22 are integrally formed. It should be understood that the support plate 2 can be integrally die-cast. Alternatively, a reduced-glue design can be employed, where redundant portions of the main body 21 are perforated to form the rib structure 22 on the main body 21, thereby increasing weight reduction and improving the regional heat dissipation capability of the support plate 2.

The battery pack in the embodiment of the present application includes the battery plastic frame as described in the above embodiment, and therefore can have all the technical features and technical effects of the above battery plastic frame, which will not be repeated here.
[0041] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant description of other embodiments.
[0042] The above is a detailed introduction to the battery frame and battery pack provided in the embodiments of the present application, and specific examples are used to illustrate the principles and implementation methods of the present application.
