Detailed Implementation

[0041] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0042] In related technologies, batteries need to be wrapped with an insulating film. The main function of the insulating film is to protect the inside of the battery from damage by the external environment, and at the same time, to prevent the battery casing from coming into contact with external metal or other conductive objects and causing a short circuit.

[0043] However, the insulating film is a single-layer structure. During battery transportation, if the battery collides with other objects in the external environment, the single-layer insulating film is easily damaged, which can lead to battery damage.

[0044] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0045] Combination Figures 1 to 3 This application provides an insulating film, comprising:

[0046] The receiving member 100 has at least one opening 110 for inserting a battery into the receiving member 100.

[0047] The closure member 200 is provided at least one, and the closure member 200 corresponds one-to-one with the opening 110. The closure member 200 is provided on the receiving member 100 and is used to open and close the opening 110.

[0048] Cover 300 is disposed on closure 200 and is used to connect to housing 100 or the side of closure 200 away from battery when closure 200 closes opening 110.

[0049] In this embodiment, the cover 300 is used to connect to the side of the receiving member 100 opposite to the battery when the closing member 200 closes the opening 110; the battery is a square battery, and the receiving member 100 is configured to cooperate with the square battery; the opening 110 is rectangular, and the closing member 200 is configured to cooperate with the rectangular opening 110; the insulating film is formed from inorganic or organic insulating materials. Commonly used inorganic insulating materials include silicon oxide, silicon nitride, aluminum oxide, and aluminum nitride; commonly used organic insulating film materials include polyimide, polyethylene, polyvinylidene fluoride, and polytetrafluoroethylene; in other embodiments, the receiving member 100 may also be a plastic part.

[0050] In this embodiment, two openings 110 are provided, one on each side of the receiving member 100, and the two openings 110 are connected. Two closing members 200 are provided, each corresponding to one of the two openings 110. In this application, when an insulating film is needed to protect the battery, the battery is inserted into the receiving member 100 along the opening 110, and the opening 110 is closed by the closing member 200. This allows the receiving member 100 and the closing member 200 to provide a single layer of protection for the battery. By using a covering member 300, when the closing member 200 closes the opening 110, the covering member 300 connects to the side of the receiving member 100 away from the battery. Through the cooperation of the receiving member 100 and the covering member 300, the covering member 300 covers the receiving member 100, thus providing double-layer protection for the battery. This prevents damage to the insulating film caused by collisions with the external environment during transport, thereby preventing battery damage.

[0051] In other embodiments, the cover 300 is used to connect to the side of the closure 200 away from the battery when the opening 110 is closed by the closure 200; by the cooperation of the closure 200 and the cover 300, the cover 300 covers the closure 200, so that the closure 200 and the cover 300 can provide double protection for the battery, and can also prevent the insulating film from being damaged due to collision with the external environment during transportation, thereby preventing battery damage.

[0052] Combination Figures 1 to 3 The closure 200 has a connecting side 210, which is rotatably connected to one side of the receiving member 100 to drive the closure 200 to open and close the opening 110.

[0053] In this embodiment, the connecting side 210 is disposed at the bottom of the closing member 200, and the connecting side 210 is rotatably connected to the bottom of the receiving member 100. The closing member 200 and the receiving member 100 are integrally disposed. Because the inorganic insulating material and the organic insulating material are flexible, the closing member 200 can be bent directly along the connection position with the receiving member 100, thereby allowing the closing member 200 to open and close the opening 110.

[0054] In other embodiments, the position of the connecting side 210 can be adjusted as needed, for example, the connecting side 210 can be set on the top of the closure 200; or the connecting side 210 formed by the crease can be set at the position where the closure 200 and the receiving member 100 are connected, so as to facilitate the bending of the closure 200.

[0055] This application uses the connecting side 210 to rotatably connect the closure 200 to the receiving member 100, so as to open and close the opening 110, which facilitates operation and improves the convenience of the closure 200 in wrapping the side of the battery.

[0056] Combination Figures 2 to 3 The cover 300 includes a first cover portion 310. The first cover portion 310 is rotatably disposed on at least one of the two sides of the closure 200 adjacent to the connection side 210. The first cover portion 310 is used to connect to the side of the accommodating member 100 away from the battery.

[0057] In this embodiment, the first covering portion 310 is rotatably provided on both sides of the closure 200 adjacent to the connecting side 210.

[0058] In this application, the first covering part 310 is integrally formed with the sealing member 200. Because the inorganic and organic insulating materials are flexible, the first covering part 310 can be bent directly along the connection position with the sealing member 200. When the sealing member 200 closes the opening 110, it drives the first covering parts 310 on both sides to rotate on the sealing member 200, so that the first covering parts 310 on both sides can rotate to the receiving part and connect with the receiving part. This allows the first covering part 310 to cooperate with the receiving part to protect the battery near the corners, thereby preventing the battery from being damaged due to the insulation film being broken.

[0059] Combination Figures 2 to 3 The cover 300 also includes a second cover 320, which is rotatably disposed on the side of the closure 200 away from the connection side 210. The second cover 320 is used to connect to the side of the housing 100 away from the battery.

[0060] In this application, the second cover 320 is integrally formed with the closure 200. Due to the flexibility of inorganic and organic insulating materials, the second cover 320 can be bent directly along the connection position with the closure 200. When the closure 200 closes the opening 110, the second cover 320 is rotated on the closure 200, so that the second cover 320 can rotate to the receiving part and connect with the receiving part. This allows the second cover 320 to cooperate with the receiving part to protect the battery near the corners, thereby further preventing the battery from being damaged due to the insulation film being broken.

[0061] Combination Figures 2 to 3 Both the first cover portion 310 and the second cover portion 320 are configured as first adhesive portions, which are used to adhere to the side of the receiving member 100 opposite to the battery.

[0062] In this embodiment, the first adhesive part is one of non-woven fabric substrate double-sided adhesive, substrate-free double-sided adhesive, and PET substrate double-sided adhesive.

[0063] By employing a first adhesive part, this application enables the first and second covering parts 310 and 320 to be directly adhered to the receiving member 100 when the first covering part 310 and the second covering part 320 are rotated. This allows the sealing member 200 to close the opening 110 through the first and second covering parts 310 and 320, eliminating the need for other structures to fix the position of the sealing member 200. This simplifies the installation steps of the insulating film and improves the convenience of installing the insulating film.

[0064] Combination Figures 2 to 3 The first covering portion 310 includes a first connecting film 311 and a first overlapping film 312. The first connecting film 311 is rotatably disposed on the closure member 200, and the first overlapping film 312 is rotatably disposed at the end of the first connecting film 311 away from the connecting side 210. The first connecting film 311 and the first overlapping film 312 are respectively connected to two adjacent surfaces of the receiving member 100.

[0065] In this embodiment, the first connecting membrane 311 is arranged along the length direction of one side edge of the closure member 200. The length of the first connecting membrane 311 is equal to the length of one side edge of the closure member 200. The sum of the lengths of the first connecting membrane 311 and the first overlapping membrane 312 is greater than the length of one side edge of the closure member 200. The first connecting membrane 311 is integrally formed with the closure member 200, and the first overlapping membrane 312 is integrally formed with the first connecting membrane 311. In other embodiments, the first overlapping membrane 312 may be provided at both ends of the first connecting membrane 311.

[0066] In this application, when the closure 200 rotates on the receiving member 100 to close the opening 110, the first connecting films 311 on both sides are rotated on the closure 200, so that the first connecting films 311 are respectively attached to the opposite sides of the receiving member 100. Then, the first overlapping film 312 is rotated on the first connecting film 311, so that the two first overlapping films 312 are connected to the same side of the receiving member 100. Thus, the first connecting films 311 on both sides and the first overlapping films 312 are connected to three different sides of the receiving member 100, thereby increasing the area of ​​the connecting film between the first covering part 310 and the receiving member 100, thereby further improving the protection effect of the battery corners.

[0067] Combination Figures 2 to 3 The second covering part 320 includes a second connecting film 321 and a second overlapping film 322. The second connecting film 321 is rotatably disposed on the sealing member 200. The second overlapping film 322 is rotatably disposed at both ends of the second connecting film 321. The second connecting film 321 is simultaneously connected to the receiving member 100 and the first overlapping film 312. The second overlapping film 322 is connected to the first connecting film 311.

[0068] In this embodiment, the second connecting membrane 321 is arranged along the length direction of one side edge of the closure member 200. The length of the second connecting membrane 321 is equal to the length of one side edge of the closure member 200. The sum of the lengths of the second connecting membrane 321 and the second overlapping membrane 322 is greater than the length of one side edge of the closure member 200. The second connecting membrane 321 is integrally formed with the closure member 200, and the second overlapping membrane 322 is integrally formed with the second connecting membrane 321.

[0069] In this application, when the closure 200 rotates on the receiving member 100 to close the opening 110, and the first connecting film 311 and the first overlapping film 312 are both pasted in place, the second connecting film 321 is rotated on the closure 200, so that the second connecting film 321, the two first overlapping films 312, and the receiving member 100 are pasted together. Then, the second overlapping film 322 is rotated on the second connecting film 321, so that the two second overlapping films 322 are pasted with the first connecting film 311. Thus, the second connecting film 321 and the second overlapping film 322 are connected to three different surfaces of the receiving member 100 again. This arrangement of the receiving member 100, the first connecting film 311, and the first overlapping film 312, together with the second connecting film 321 and the second overlapping film 322, further increases the thickness of the receiving member 100 near the battery corner, thereby further preventing damage to the insulating film at the position corresponding to the battery corner, and thus preventing damage to the battery corner.

[0070] In this embodiment, both the first overlapping film 312 and the second overlapping film 322 are triangular, and the first overlapping film 312 and the second overlapping film 322 spliced ​​together are rectangular. In other embodiments, the shapes of the first overlapping film 312 and the second overlapping film 322 can be adaptively adjusted as needed. For example, the first overlapping film 312 and the second overlapping film 322 can be set as semi-circular, or the first overlapping film 312 and the second overlapping film 322 can be set as square.

[0071] Combination Figures 2 to 3 The closure 200 is provided with an opening 220 for the battery tabs to pass through.

[0072] Combination Figures 2 to 3 The opening 220 includes a first strip hole 221 and a plurality of second strip holes 222. The plurality of second strip holes 222 are arranged at intervals along the extending direction of the first strip hole 221, and the second strip holes 222 are connected to the first strip hole 221.

[0073] In this embodiment, the two ends of the first strip hole 221 extend toward the positions of the first connecting membranes 311 on both sides. The first strip hole 221 is parallel to the second connecting membrane 321. A plurality of second strip holes 222 are respectively disposed on both sides of the length direction of the first strip hole 221. The second strip holes 222 are perpendicular to the first strip hole 221. All the second strip holes 222 are parallel to the first connecting membrane 311.

[0074] By employing multiple second strip-shaped holes 222, this application can divide the first strip-shaped hole 221 into multiple overlapping portions 223 along its circumferential direction and the peripheral wall of the first strip-shaped hole 221. When the battery tab passes through the first strip-shaped hole 221, the multiple overlapping portions 223 can overlap on the tab, allowing the tab to pass through the first strip-shaped hole 221 more smoothly. Furthermore, the overlapping portions 223 prevent welding slag generated during tab welding from affecting the use of the tab, thereby improving the safety of tab use.

[0075] Combination Figure 1 , Figure 2 and Figure 4 The receiving member 100 includes a first mounting part 120, a second mounting part 130, a third mounting part 140 and a fourth mounting part 150. The second mounting part 130 and the third mounting part 140 are rotatably disposed on opposite sides of the first mounting part 120, and the fourth mounting part 150 is rotatably disposed on the side of the second mounting part 130 away from the first mounting part 120. The side of the fourth mounting part 150 away from the third mounting part 140 is used to connect with the second mounting part 130.

[0076] In this embodiment, the first mounting portion 120, the second mounting portion 130, the third mounting portion 140, and the fourth mounting portion 150 are integrally formed mounting films. The widths of the first mounting portion 120, the second mounting portion 130, the third mounting portion 140, and the fourth mounting portion 150 along the two side closures 200 are all the same. The first mounting portion 120, the second mounting portion 130, the third mounting portion 140, and the fourth mounting portion 150 are used to connect to the four circumferential faces of the square battery, respectively. The lengths of the first mounting portion 120, the second mounting portion 130, the third mounting portion 140, and the fourth mounting portion 150 can be adaptively adjusted according to the size of each face of the square battery.

[0077] Combination Figure 1 , Figure 2 and Figure 4In this embodiment, when the first connecting film 311 rotates on the closure 200, the first connecting films 311 on both sides of the closure 200 can be connected to the second mounting portion 130 and the third mounting portion 140 respectively. When the first overlapping film 312 rotates on the first connecting film 311, the first overlapping film 312 on both sides of the first connecting film 311 can be connected to the fourth mounting portion 150. When the second connecting film 321 rotates on the closure 200, the second connecting film 321 can be connected to the fourth mounting portion 150 and the first overlapping films 312 on both sides. When the second overlapping film 322 rotates on the second connecting film 321, the second overlapping films 322 at both ends of the second connecting film 321 can be connected to the first connecting films 311 on the second mounting portion 130 and the third mounting portion 140 respectively.

[0078] In other embodiments, the second connecting film 321 can be rotated on the sealing member 200 first. At this time, the second connecting film 321 can be connected to the fourth mounting part 150, and the second overlapping films 322 at both ends of the second connecting film 321 can be connected to the second mounting part 130 and the third mounting part 140 respectively. After rotation, the first connecting films 311 on both sides of the sealing member 200 can be connected to the second mounting part 130 and the third mounting part 140 and the second overlapping films 322 on the second mounting part 130 and the third mounting part 140 respectively. After rotation, the first overlapping film 312 can be connected to the second connecting film 321, thereby achieving multi-layer protection of the battery.

[0079] Combination Figure 1 , Figure 2 and Figure 4 The second mounting part 130 is rotatably provided with a first splicing part 131 on the side away from the first mounting part 120. The first splicing part 131 is used to connect with the battery. The fourth mounting part 150 is rotatably provided with a second splicing part 151 on the side away from the third mounting part 140. The second splicing part 151 is used to connect with the second mounting part 130.

[0080] In this embodiment, after the first splicing part 131 rotates on the second mounting part 130, the second mounting part 130 and the first splicing part 131 can be connected to two adjacent surfaces of the battery respectively. After the fourth mounting part 150 rotates on the third mounting part 140, the fourth mounting part 150 can wrap the battery and connect with the first splicing part 131. After the second splicing part 151 rotates on the fourth mounting part 150, the second splicing part 151 can pass over the first splicing part 131 and connect with the second mounting part 130. This allows the second mounting part 130 and the fourth mounting part 150 to work together with the first splicing part 131 and the second splicing part 151 to provide double-layer protection for the corners of the battery, thereby further preventing damage to the insulating film and thus the battery from being damaged.

[0081] Combination Figure 1 , Figure 2 andFigure 4 The second splicing part 151 is provided with a plurality of second adhesive parts 152 at intervals on the side away from the fourth mounting part 150, and the plurality of second adhesive parts 152 are used to be adhesive to the second mounting part 130.

[0082] In this embodiment, four second adhesive portions 152 are provided, and the four second adhesive portions 152 are spaced apart and evenly arranged along the length direction of the second splicing portion 151; the second adhesive portion 152 is one of non-woven fabric substrate double-sided adhesive, substrate-free double-sided adhesive and PET substrate double-sided adhesive.

[0083] This application employs multiple second adhesive portions 152, allowing the entire housing 100 to completely cover the four adjacent sides of the battery after the second adhesive portions 152 are attached to the second mounting portions 130. This simplifies the assembly of the housing 100 and improves its ease of assembly. Furthermore, by spaced the multiple second adhesive portions 152 together, air bubbles can be prevented from forming when attaching a single, narrow second adhesive portion 152 to the second mounting portion 130, thereby improving the adhesion between the second adhesive portion 152 and the second mounting portion 130.

[0084] like Figure 2 As shown, along the direction of the second splicing part 151 away from the fourth mounting part 150, the width between the two opposite sides of the second adhesive part 152 gradually increases.

[0085] In this embodiment, the second adhesive part 152 is configured as an isosceles trapezoid, with the short side of the isosceles trapezoid connected to the fourth mounting part 150, and the long side of the isosceles trapezoid located on the side away from the fourth mounting part 150. The second adhesive part 152 can be connected to the fourth mounting part 150 by heat fusion or by adhesive. In other embodiments, the shape of the second adhesive part 152 can be adaptively adjusted as needed, for example, the second adhesive part 152 can be configured as a triangle or a semicircle.

[0086] This application improves the adhesion between the second adhesive part 152 and the second mounting part 130 by setting the second adhesive part 152 as an isosceles trapezoid, which prevents air bubbles from being generated during the adhesive process and increases the connection area between the second adhesive part 152 and the second mounting part 130.

[0087] Combination Figure 2 and Figure 3 Multiple vent holes 400 are provided on the sealing part 200, the second mounting part 130 and the third mounting part 140.

[0088] In this embodiment, a plurality of vent holes 400 are provided on the closure 200 and on both sides of the opening 220.

[0096] ​The electrical equipment provided in this application, by setting up a battery, when it is necessary to use an insulating film to protect the battery, firstly places the battery on the first mounting part 120. At this time, by driving the second mounting part 130 to rotate on the first mounting part 120, the second mounting part 130 covers one side of the battery. Then, by driving the first splicing part 131 to rotate on the second mounting part 130, the first splicing part 131 covers the top wall of the battery. Next, by driving the third mounting part 140 to rotate on the first mounting part 120, the third mounting part 140 covers the other side of the battery. Finally, by driving the fourth mounting part 150 on the third mounting part 140... The fourth mounting portion 150 is rotated on the fourth mounting portion 150, so that it covers the top wall of the battery. At this time, the fourth mounting portion 150 can cover the first splicing portion 131. By driving the second splicing portion 151 to rotate on the fourth mounting portion 150, the second splicing portion 151 covers the second mounting portion 130. At this time, the second splicing portion 151 is fixed to the second mounting portion 130 by the second adhesive portion 152, so that the first mounting portion 120, the second mounting portion 130, the third mounting portion 140 and the fourth mounting portion 150 form a receiving member 100 that covers the four adjacent surfaces of the battery. By driving the closing member 200 to rotate within the receiving member... The bottom side of component 100 rotates, causing the closure 200 to close the opening 110 of the receiving component 100. The battery tabs can pass through the first strip hole 221 and the second strip hole 222. At this time, by driving the first connecting films 311 on both sides of the closure 200 to rotate on the closure 200, the first connecting film 311 on one side of the closure 200 can be pasted with the second mounting part 130 and the second splicing part 151, and the first connecting film 311 on the other side of the closure 200 can be pasted with the third mounting part 140. By driving the first overlapping film 312 to rotate on the first connecting film 311, the first connecting films 311 on both sides can rotate. The first overlapping film 312 on 1 is adhered to the fourth mounting part 150. By driving the second connecting film 321 to rotate on the sealing member 200, the second connecting film 321 is simultaneously adhered to the first overlapping film 312 on both sides and the fourth mounting part 150. By driving the second overlapping film 322 to rotate on the second connecting film 321, the second overlapping film 322 at both ends of the second connecting film 321 is adhered to the first connecting film 311. Thus, the insulating film protects the battery, and the corners of the battery can achieve multi-layer protection, thereby preventing the insulating film from being damaged due to collision with the external environment during battery transportation, and thus preventing battery damage.
