[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0026] like Figure 1 As shown, an embodiment of the utility model provides a Mylar component, which includes a base film 10 and multiple side films that are integrally connected. The front side of the base film 10 and the front sides of the multiple side films can be fitted with the battery cell. The front side of the base film 10 is provided with a bonding area 11 and a non-glue area 12. The bonding area 11 of the base film 10 and the front sides of the multiple side films are both provided with an adhesive layer for bonding to the battery cell. The non-glue area 12 corresponds to the internal supporting ribs of the battery cell, and the base film 10 is provided with an anti-abnormal noise structure 20 corresponding to the non-glue area 12.

[0027] The Mylar component provided in this embodiment is applied, and the Mylar component includes a bottom film 10 and multiple side films that are integrally connected. The Mylar component is wrapped on the surface of the battery cell and fixed with an adhesive layer. At this time, the glue-free area 12 corresponding to the internal support ribs of the battery cell is in a relatively sealed state. By providing an anti-abnormal sound structure 20 corresponding to the glue-free area 12 on the bottom film 10, it is possible to prevent the bottom film 10 corresponding to the glue-free area 12 from forming bulges or wrinkles when the battery is pressed, thereby eliminating the abnormal noise associated with the bulges and wrinkles, improving the installation effect of the Mylar component and the user experience, improving production efficiency and production yield, and reducing production costs.

[0028] Among them, the anti-abnormal noise structure 20 corresponding to the non-glue area 12 is provided on the base film 10, which means that the anti-abnormal noise structure 20 is located within the projection position of the non-glue area 12 on the base film 10, and if there are multiple non-glue areas 12, each non-glue area 12 is correspondingly provided with an anti-abnormal noise structure 20.

[0029] It should be noted that the inventors found that the main reason for the abnormal noise generated by the Mylar component in the related art is that after the Mylar component is wrapped on the surface of the battery cell and fixed with an adhesive layer, there is a relatively sealed space between the portion of the base film 10 corresponding to the glue-free area of ​​the Mylar component and the battery cell. When the battery is pressed (for example, the user presses the computer keyboard surface, and the battery of the laptop computer is indirectly pressed), the air pressure in the relatively sealed space between the portion of the base film 10 corresponding to the glue-free area and the battery cell changes, causing stress concentration in the base film 10, etc., which causes the portion of the base film 10 corresponding to the glue-free area to become wrinkled or bulged, generating abnormal noise.

[0030] Furthermore, compared with the related art method of replacing the base film 10 with noise-reducing Mylar, this embodiment avoids increasing the cost of the Mylar component and shortens the delivery cycle of the Mylar component by providing an anti-sound structure 20 corresponding to the glue-free area 12 on the base film 10.

[0031] like Figure 1 As shown, the anti-abnormal noise structure 20 includes a cut-off line 21 and / or an indentation line 22. When pressing the battery, the indentation line 22 can remove the stress of the bottom film 10 corresponding to the non-glue area 12, avoiding stress concentration, thereby preventing wrinkles from causing abnormal noises, and the cut-off line 21 can discharge the air between the bottom film 10 corresponding to the non-glue area 12 and the battery cell, avoiding wrinkles or bulges, and avoiding abnormal noises.

[0032] like Figure 1 As shown, the glue-free area 12 includes an end area 121 and an inner area 122. The end area 121 extends along the width direction of the battery cell. The end area 121 is located at the end of the bottom film 10 in the length direction of the battery cell. The inner area 122 is located inside the bottom film 10 in the length direction of the battery cell. The anti-abnormal sound structure 20 is arranged corresponding to the inner area 122. When the Mylar piece is wrapped on the surface of the battery cell and fixed with the adhesive layer, the gas between the bottom film 10 corresponding to the inner area 122 and the battery cell is difficult to discharge. By arranging the anti-abnormal sound structure 20 corresponding to the inner area 122, the anti-abnormal sound structure 20 can be used to prevent the bottom film 10 corresponding to the inner area 122 from forming bulges or wrinkles, thereby avoiding abnormal sounds.

[0033] Among them, the corresponding arrangement of the anti-abnormal noise structure 20 and the internal area 122 means that the anti-abnormal noise structure 20 is located within the projection position of the internal area 122 on the base film 10, and if there are multiple internal areas 122, each internal area 122 is correspondingly provided with an anti-abnormal noise structure 20.

[0034] like Figure 1 As shown, there are two glue-free areas 12 symmetrically arranged in the length direction of the battery cell. Since the length of the battery cell is greater than the width of the battery cell, the gas flow effect between the bottom film 10 corresponding to the glue-free area 12 and the battery cell in the length direction of the battery cell is poor. By using two glue-free areas 12 symmetrically arranged in the length direction of the battery cell, and both of the two glue-free areas 12 are provided with an anti-abnormal sound structure 20, it is possible to prevent the bottom film 10 corresponding to the two glue-free areas 12 from generating abnormal sounds, thereby preventing the fluidity of the gas in the length direction of the battery cell from interfering with the reliability of the anti-abnormal sound structure 20.

[0035] like Figure 1 As shown, the internal area 122 includes a transverse area 1221 extending along the length direction of the battery cell and a longitudinal area 1222 extending along the width direction of the battery cell. The two ends of the transverse area 1221 are respectively connected to the middle of the end area 121 and the middle of the longitudinal area 1222, and the anti-abnormal noise structure 20 is respectively arranged corresponding to the transverse area 1221 and the longitudinal area 1222.

[0036] like Figure 1 As shown, the anti-abnormal noise structure 20 includes an indentation line 22, which extends along the width direction of the battery cell and is arranged in the longitudinal area 1222. When pressing the battery, the indentation line 22 can remove the stress of the bottom film 10 corresponding to the longitudinal area 1222, avoiding stress concentration, thereby preventing wrinkles from causing abnormal noise.

[0037] like Figure 1 As shown, at least two indentation lines 22 are arranged in parallel in the longitudinal region 1222 .

[0038] like Figure 1 As shown, the abnormal noise prevention structure 20 includes a cutting line 21, which extends along the length direction of the battery cell and is arranged in the transverse area 1221. When pressing the battery, the cutting line 21 can be used to discharge the air between the bottom film 10 and the battery cell corresponding to the transverse area 1221, thereby avoiding wrinkles or bulges and abnormal noise.

[0039] like Figure 1 As shown, the cutting line 21 includes a plurality of cutting holes arranged at intervals along the length direction of the battery cell, and the cutting holes penetrate the front and back sides of the Mylar component. When the battery is pressed, the air between the bottom film 10 and the battery cell corresponding to the lateral area 1221 can be discharged through the cutting holes.

[0040] like Figure 1As shown, the multiple side membranes include a first side membrane 30, a second side membrane 40, a third side membrane 50 and a fourth side membrane 60. The first side membrane 30 and the second side membrane 40 are respectively arranged on both sides of the bottom membrane 10 in the width direction of the battery cell, and the third side membrane 50 and the fourth side membrane 60 are respectively arranged on both sides of the bottom membrane 10 in the length direction of the battery cell perpendicular to the width direction of the battery cell.

[0041] like Figure 1 As shown, the Mylar piece also includes a fold line 70, which is arranged at the connection between the first side film 30, the second side film 40, the third side film 50, the fourth side film 60 and the bottom film 10 and the first side film 30, the second side film 40, the third side film 50 and the fourth side film 60. The fold line 70 corresponds to the edge of the battery cell, and the fold line 70 adopts a cut-off line structure. When pressing the battery, if the air pressure between the bottom film 10 corresponding to the end area 121 and the battery cell changes greatly, the air between the bottom film 10 corresponding to the end area 121 and the battery cell can be discharged through the fold line 70 with a cut-off line structure, avoiding wrinkles or bulging, and avoiding abnormal noise. When wrapping the Mylar piece on the battery cell, the fold line 70 can be used as a positioning reference, and the Mylar piece can be easily folded, thereby improving the wrapping efficiency and effect of the Mylar piece.

[0042] Another embodiment of the utility model provides a battery, the battery includes a battery cell and a Mylar component, the Mylar component is wrapped on the battery cell, and the Mylar component is the Mylar component provided above. The Mylar component is wrapped on the surface of the battery cell and fixed with an adhesive layer, at which time the glue-free area 12 corresponding to the internal support ribs of the battery cell is in a relatively sealed state, and by providing an anti-abnormal sound structure 20 corresponding to the glue-free area 12 on the bottom film 10, it is possible to prevent the bottom film 10 corresponding to the glue-free area 12 from forming bulges or wrinkles when pressing the battery, thereby eliminating abnormal sounds associated with the bulges and wrinkles, improving the installation effect of the Mylar component and the user experience, improving production efficiency and production yield, and reducing production costs.

[0043] Another embodiment of the utility model provides a laptop computer, which includes the battery provided above. The Mylar component is wrapped on the surface of the battery cell and fixed by using an adhesive layer. At this time, the glue-free area 12 corresponding to the internal support ribs of the battery cell is in a relatively sealed state. By setting an anti-abnormal noise structure 20 corresponding to the glue-free area 12 on the bottom film 10, it is possible to prevent the bottom film 10 corresponding to the glue-free area 12 from forming bulges or wrinkles when pressing the battery, thereby eliminating abnormal noises associated with the bulges and wrinkles, improving the installation effect of the Mylar component and the user's experience, improving production efficiency and production yield, reducing production costs, and solving the problem of abnormal noises in the laptop battery when the user presses the computer keyboard surface.
