Battery plastic frame, battery and electronic device

Abstract

This application relates to the field of battery technology, and in particular to a plastic frame for a battery, a battery, and an electronic device. The plastic frame for the battery includes a frame body and reinforcing plates. Each corner structure of the frame body has a fitted reinforcing plate embedded therein, so that the reinforcing plate covers the outer surface of the corner structure and that the outer surface of the reinforcing plate does not protrude from the outer surface of the frame body. Thus, the reinforcing plates strengthen the corner structures of the frame body, preventing damage at the corners when the frame body is impacted, which would affect the integrity of the laptop battery's appearance and overall safety. Simultaneously, by embedding the reinforcing plates, the installation of the reinforcing plates on the frame body is strengthened, without affecting the overall dimensions of the frame body. The thickness of the side frame of the frame body does not need to be increased, avoiding the problem of increased weight for the laptop battery. Furthermore, when the battery is installed in the battery compartment, the frame body can better abut against the battery compartment body.

Description

Technical Field

[0001] This application relates to the field of battery technology, and in particular to a plastic frame for a battery, a battery, and an electronic device. Background Technology

[0002] With the rapid development of the laptop market, consumers have increasingly higher demands for portability, which has driven the trend of making laptops thinner and lighter, and has also promoted the development of laptop batteries towards lighter weight.

[0003] Currently, to reduce weight and control costs, laptop battery frames are typically made of plastic. Due to space constraints within the laptop, these frames are often relatively thin, making them prone to cracking under external impact, especially at the corners. Such cracking not only affects the battery's appearance but can also damage the internal cells, potentially leading to safety hazards. While adding reinforcement structures at the corners can increase the strength of the plastic frame, it also affects the frame's dimensions, taking up space. Utility Model Content

[0004] The purpose of this invention is to provide a plastic frame for a battery, a battery, and an electronic device, so as to strengthen the corner positions of the plastic frame without affecting the size of the plastic frame.

[0005] The first aspect of this utility model provides a plastic frame for a battery, including a frame body and a reinforcing sheet;

[0006] The frame body has multiple corner structures, and each corner structure is embedded with a matching reinforcing piece, so that the reinforcing piece covers the outer surface of the corner structure and the outer surface of the reinforcing piece does not protrude from the outer surface of the frame body.

[0007] Furthermore, the reinforcing sheet is embedded in the corner structure by in-mold injection molding.

[0008] Furthermore, the reinforcing sheet includes two reinforcing parts connected at an angle, the connection angle between the two reinforcing parts is adapted to the angle of the corner structure, and each of the two reinforcing parts is provided with a through hole.

[0009] Furthermore, the through hole is tapered, and the diameter of the through hole gradually decreases from one end near the outer surface of the frame body to the other end.

[0010] Furthermore, the ends of the two reinforcing parts that are far apart from each other are both bent into a U-shape towards the interior of the frame body.

[0011] Furthermore, the radius of the outer R-angle of the U-shaped ends of the two reinforcing parts is 0.5 mm to 0.7 mm.

[0012] Furthermore, the two reinforcing portions extend in the circumferential direction of the frame body by an amount of 6 mm to 10 mm.

[0013] Furthermore, the reinforcing sheet is a stainless steel reinforcing sheet, a titanium alloy reinforcing sheet, an aluminum alloy reinforcing sheet, a copper reinforcing sheet, an aluminum reinforcing sheet, or a carbon fiber reinforcing sheet.

[0014] A second aspect of this utility model provides a battery, including a plastic frame and a cell assembly of the battery as described in any of the above claims, wherein the cell assembly is disposed within the plastic frame of the battery.

[0015] A third aspect of this invention provides an electronic device comprising the battery described above.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] The plastic frame of the battery provided by this utility model includes a frame body and reinforcing sheets. The frame body has multiple corner structures, and each corner structure is embedded with a matching reinforcing sheet, so that the reinforcing sheet covers the outer surface of the corner structure. The reinforcing sheet forms a covering of the corner structure of the frame body, thereby strengthening the corner structure of the frame body and preventing damage to the corner position of the frame body when subjected to external impact, which would affect the integrity of the appearance of the laptop battery and the overall safety.

[0018] Meanwhile, the outer surface of the reinforcing plate does not protrude from the outer surface of the frame body. This not only increases the firmness of the reinforcing plate at the corner structure through embedding, but also does not affect the external dimensions of the frame body. The thickness of the side frame that makes up the frame body does not need to be increased, avoiding the problem of increasing the weight of the laptop battery. When the battery is installed in the battery compartment, the plastic frame of the battery can also better abut against the battery compartment body.

[0019] This utility model also provides a battery and an electronic device including the battery, the battery including a plastic frame of the battery, and thus the battery and the electronic device also have the beneficial effects of the plastic frame of the battery. Attached Figure Description

[0031] The following reference Figures 1 to 3 This application describes a plastic frame for a battery, a battery, and an electronic device according to some embodiments thereof.

[0032] The first aspect of this application provides a plastic frame for a battery, such as... Figure 1 and Figure 2 As shown, the plastic frame of the battery includes a frame body 1 and a reinforcing plate 2. The frame body 1 is a square frame formed by connecting multiple side frames end to end. The interior of the frame body 1 is used to install the battery cells of the laptop battery, so that the frame body 1 can protect the battery cells. At the same time, the laptop battery is fixedly connected to the battery compartment of the laptop through the frame body 1. The frame body 1 forms a corner structure at the connection between any two adjacent side frames. Each corner structure is embedded with a matching reinforcing plate, so that the reinforcing plate covers the outer surface of the corner structure, so that the reinforcing plate can cover the corner structure of the frame body. Thus, the reinforcing plate 2 can strengthen the corner structure of the frame body 1, so as to prevent the corner position of the frame body 1 from being damaged when subjected to external impact, which would affect the integrity of the appearance of the laptop battery and the overall safety.

[0033] Meanwhile, the outer surface of the reinforcing piece 2 (i.e., the surface of the reinforcing piece 2 facing the outside of the frame body 1) does not protrude from the outer surface of the frame body 1. Preferably, the outer surface of the reinforcing piece 2 is flush with the outer surface of the frame body 1. Thus, the reinforcing piece 2 can be installed more securely at the corner structure by embedding, without affecting the external dimensions of the frame body 1. The thickness of the side frame that makes up the frame body 1 does not need to be increased, avoiding the problem of increased weight of the laptop battery. At the same time, when the battery is installed in the battery compartment, the frame body can better abut against the battery compartment.

[0034] In this embodiment, preferably, the reinforcing piece 2 is embedded in the corner structure of the frame body 1 by in-mold injection molding, thereby connecting the reinforcing piece 2 and the frame body 1 into one unit, improving processing efficiency, reducing processing costs, and ensuring that the reinforcing piece 2 maintains good firmness at the corner structure of the frame body 1, making it less likely to fall off. This effectively strengthens the corner structure of the frame body 1. It also makes it easier to control the overall dimensions of the frame body 1 and the reinforcing piece 2 after they are integrated, ensuring that the thickness of the side frame and the corner structure of the frame body 1 does not increase, thus preventing an increase in battery weight. This also allows the frame body to better abut against the battery compartment when the battery is installed inside.

[0035] In one embodiment of this application, preferably, as shown below, Figure 1 and Figure 2 As shown, the reinforcing sheet 2 includes two reinforcing parts 21 connected at an angle. The connection angle between the two reinforcing parts 21 is adapted to the angle of the corner structure. For example, if the corner of the frame body 1 is a 90° corner, the reinforcing sheet 2 is L-shaped as a whole, and the two reinforcing parts 21 of the reinforcing sheet 2 are connected at 90°, so that the reinforcing sheet 2 can cover the corner structure appropriately. Of course, depending on the shape of the battery, the corner of the frame body 1 can also be other angles besides 0° and 180°, such as 60°, 120° or 150°, and the corresponding connection angle between the two reinforcing parts 21 of the reinforcing sheet 2 is also set to 60°, 120° or 150°.

[0036] In this embodiment, preferably, as follows: Figure 2 As shown, both reinforcing portions 21 of the reinforcing sheet 2 are provided with through holes 22. When the reinforcing sheet 2 is connected to the frame body 1 by in-mold injection molding, the injection molten material forming the frame body 1 can flow into the through holes 22 of the reinforcing sheet 2 and solidify. This makes the reinforcing sheet 2 more stably and firmly embedded in the corner structure of the frame body 1, improving the connection strength and stability between the reinforcing sheet 2 and the frame body 1. This allows the reinforcing sheet 2 to effectively provide strength reinforcement for the frame body 1 at the corner structure.

[0037] Regarding the through hole 22 on the reinforcing piece 2, in one embodiment of this application, preferably, one end of the through hole 22 in the axial direction is the first end, and the other end of the through hole 22 in the axial direction is the second end. The first end of the through hole 22 faces the outside of the frame body 1, and the second end of the through hole 22 faces the inside of the frame body 1. The through hole 22 is tapered, so that the diameter of the through hole 22 gradually decreases from the first end to the second end, thereby enabling the injection part formed in the through hole 22 by the injection molding material to form a snap-fit ​​on the reinforcing piece, so that the frame body 1 and the reinforcing piece 2, which are integrally connected after molding, are more firmly connected.

[0038] More preferably, the two reinforcing portions 21 of the reinforcing piece 2 are provided with a plurality of through holes 22 at intervals to further enhance the connection between the frame body 1 and the reinforcing piece 2.

[0039] In one embodiment of this application, preferably, both reinforcing portions 21 of the reinforcing sheet 2 have free ends that are far apart from each other, and the free ends of both reinforcing portions 21 are bent into a U-shape toward the interior of the frame body 1. This can enhance the adhesive strength of the reinforcing sheet 2, which is embedded in the frame body 1 by in-mold injection molding, and improve the connection firmness of the reinforcing sheet 2 on the frame body 1.

[0040] In one embodiment of this application, preferably, as shown below, Figure 3 As shown, the radius of the outer R-angle of the U-shaped end (i.e., the free end) of each reinforcing part 21 is 0.5 mm to 0.7 mm; that is, for the U-shaped portion of the reinforcing part 21, the distance d between the surfaces of the two parallel parts that are far from each other is 1.0 mm to 1.4 mm. The thickness of the side frame at the corner of the frame body 1 is not less than the above-mentioned distance d, so that when the reinforcing sheet 2 is injection molded into the frame body 1, the reinforcing part 21 can be completely embedded in the side frame of the frame body 1, and the reinforcing part 21 will not extend into the inside of the frame body 1 and affect the battery cell inside the frame body 1.

[0041] In one embodiment of this application, preferably, as shown below, Figure 3 As shown, the two reinforcing portions 21 of the reinforcing plate 2 extend by a dimension L of 6mm to 10mm along the circumferential direction of the frame body 1; that is, the dimension of the reinforcing portion 21 along the length of the side frame of the frame body 1 is 6mm to 10mm. This ensures that the reinforcing plate 2 has sufficient coverage area at the corner structure of the frame body 1, effectively providing strength reinforcement and ensuring the firmness of the connection between the reinforcing plate 2 and the frame body 1.

[0042] In one embodiment of this application, preferably, the reinforcing sheet 2 is a stainless steel reinforcing sheet 2, a titanium alloy reinforcing sheet 2, an aluminum alloy reinforcing sheet 2, a copper reinforcing sheet 2, an aluminum reinforcing sheet 2, or a carbon fiber reinforcing sheet 2. This ensures that the reinforcing sheet 2 has sufficient strength to effectively reinforce the frame body 1, preventing the corners of the frame body 1 from easily breaking when subjected to impact.

[0043] A second aspect of this application provides a battery, including a cell assembly and a plastic frame of the battery according to any of the above embodiments, wherein the cell assembly is disposed within the plastic frame of the battery.

[0044] In this embodiment, the battery includes a plastic frame, and therefore the battery has all the beneficial effects of the plastic frame, which will not be described in detail here.

[0045] A third aspect of this application provides an electronic device that includes the battery of any of the above embodiments. Therefore, the electronic device also has all the beneficial effects of the plastic frame of the battery, which will not be described in detail here.

[0046] 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.
