Obviously, the following drawings are only some embodiments of the present utility model, and those of ordinary skill in the art can also obtain other drawings based on these drawings without creative labor.

[0030] In the related art, the battery fixing structure in an electronic device will increase the thickness of the battery due to the presence of the peelable sticker, thereby affecting the battery capacity. For the sake of easy understanding, the problems of the battery fixing structure in the related art are described below in conjunction with Figure 7 This is to illustrate the problems of the battery fixing structure in the related art.

[0031] As Figure 7 shown in, the existing battery fixing structure includes a battery 1, a side glue 2, a peelable sticker 3 and a double-sided tape 4. Among them, the peelable sticker 3 is wrapped on the front, back and one side of the battery 1. One side of the double-sided tape 4 is attached to the peelable sticker 2, and the other side of the double-sided tape 4 is attached to an electronic device (such as a mobile phone), so as to fix the battery 1 inside the electronic device. The thickness of the peelable sticker 3 is generally 0.35mm - 0.08mm. Taking the peelable sticker 3 with a thickness of 0.06mm as an example for illustration:

[0032] Since the space for accommodating the battery in the electronic device is certain, if the peelable sticker 3 with a thickness of 0.06mm is used in the battery fixing structure, then the size of the battery 1 in its width direction will be lost by 0.06mm, and the size in its thickness direction will be lost by 0.12mm, thereby limiting the capacity of the battery 1. For the same-sized battery accommodation space, if the peelable sticker 3 is not used, the corresponding sizes can be increased in the width and thickness directions of the battery 1, so that the battery capacity or energy density can be increased by 1 - 4%.

[0033] However, if the tearable sticker 3 is removed and the battery 1 is removed only by the handle pasted on the side of the battery 1, since the bonding area between the handle and the battery 1 is small, if the bonding force of the double-sided tape 4 is overcome to remove the battery 1, the handle may fall off from the battery 1 while the battery 1 is not taken out. Therefore, in the case of meeting the requirements of the firm adhesion between the battery 1 and the electronic device and also taking into account the convenience of disassembly, the present application provides a battery fixing structure with weakened adhesion under specific circumstances.

[0034] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0035] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative position relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

The terms "including" and / or "comprising" are used to specify the existence of the described elements, steps, operations and / or components, but do not exclude the existence or addition of one or more other elements, steps, operations and / or components.

In addition, in the description of the present utility model, unless otherwise stated, the meaning of "a plurality of" is two or more. These terms are only used to distinguish one element from another. In combination with the following drawings, these and / or other aspects become obvious, and those of ordinary skill in the art will more easily understand the description of the embodiments of the present utility model. The drawings are only used to depict the embodiments of the present utility model for illustrative purposes. Those skilled in the art will easily recognize from the following description that alternative embodiments of the structure and method shown in the present utility model can be adopted without departing from the principles described in the present utility model.

[0037] Figure 1 It is an exploded view of a battery fixing structure according to an embodiment of the present utility model. For the convenience of understanding, in the figure, the X-axis direction is the width direction of the battery 10, the Y-axis direction is the length direction of the battery 10, and the Z-axis direction is the thickness direction of the battery 10.

[0038] As Figure 1-2As shown, the battery fixing structure includes a handle 30 and an alcohol glue 20. Among them:

[0039] The handle, also known as the lift up handle, is wrapped around one side of the battery and is used to lift or pull out the battery from the electronic device; the alcohol glue is attached to the first surface of the battery and is used to attach the battery to the electronic device.

[0040] Furthermore, as Figure 1 、 4 、shown in Figure 5, the upper ends of the two side edges of the battery 10 in the length direction are bent towards the top edge of the battery 10 to form a bend 103. The dimensions of the battery 10 in both the length direction and the width direction are reduced, thereby reducing the occupied space of the battery 10 in the electronic device and further reducing the interference of the battery 10 on the electronic device.

[0041] In an alternative embodiment, the battery fixing structure further includes an insulating tape 40. The handle 30 and the insulating tape 40 are respectively located on two opposite sides of the battery 10. For example, the handle 30 and the insulating tape 40 are respectively located on the two side edges of the battery 10 in the length direction. One side of the alcohol glue 20 is attached to the first surface of the battery 10 (for example, the back surface of the battery), and the other side of the alcohol glue 20 is attached to the electronic device, thereby fixing the battery 10 in the electronic device. Taking a mobile phone as an example, there is a compartment for accommodating the battery in the mobile phone. One side of the alcohol glue 20 is attached to the back surface of the battery 10, and the other side of the alcohol glue 20 is attached to the compartment, thereby fixing the battery 10 in the compartment to supply power to the mobile phone. The use of the easy-to-tear sticker is avoided in this battery fixing structure, effectively reducing the dimensions of the battery fixing structure in the width and thickness directions. For the same accommodation space, the capacity of the battery 10 can be increased, improving the user experience. The main component of the alcohol glue 20 is an acrylic synthetic resin polymer, which has the properties of high viscosity and high stability. When the alcohol glue 20 encounters alcohol, alcohol, as an efficient organic solvent, can quickly dissolve the alcohol glue 20, resulting in a weakened or disappeared viscosity of the alcohol glue 20. When the battery 10 needs to be replaced, the alcohol glue 20 can be dissolved by alcohol, reducing the adhesion between the battery 10 and the compartment. Thus, even without the easy-to-tear sticker, the battery 10 can be removed only by the handle 30.

[0042] Specifically, the handle 30 and the insulating tape 40 are strip-shaped grooves with openings at both ends. The handle 30 and the insulating tape 40 are respectively adhered to the front and back of the battery 10 through the protruding edges (also called flanges) on both sides thereof. Thus, the handle 30 and the insulating tape 40 are wrapped around the two side edges of the battery 10 in the length direction. On the one hand, it can play an insulating role for the two side edges of the battery 10 to prevent short circuits between the side edges of the battery 10 and the machine compartment; on the other hand, the battery 10 can be easily disassembled through the handle 30.

[0043] The lengths and / or widths of the handle 30 and the insulating tape 40 can be the same or different. For example, in this embodiment, the lengths of the handle 30 and the insulating tape 40 are equal, and the widths of the protruding edges on both sides of the handle 30 can be greater than the widths of the protruding edges on both sides of the insulating tape 40. The wider edge of the handle 30 facilitates applying a pulling force to the battery 10 through the handle 30, making it convenient to disassemble the battery 10. The width of the edge of the handle 30 can be set to 5 - 10 mm, such as 6 mm, 7 mm, 8 mm, or 9 mm, etc. That is, it is ensured that the pasting width of the handle 30 on the front or back of the battery 10 is within the range of 5 - 10 mm. The narrower edge of the insulating tape 40 can leave more bonding space for the alcohol glue 20, thereby improving the fixing effect of the battery 10.

[0044] The material of the handle 30 is, for example, polyethylene terephthalate (PET) or polyimide (PI). The material of the insulating tape 40 is, for example, polyimide (PI). Among them, polyethylene terephthalate has excellent physical and mechanical properties within a wide temperature range and also has excellent electrical insulation; polyimide has a wide operating temperature range and also has high insulation performance. Therefore, using polyethylene terephthalate or polyimide for the handle 30 and polyimide for the insulating tape 40 can both achieve a good insulating effect on the battery 10. In applications, other materials can also be selected to make the handle 30 and the insulating tape 40 according to needs, as long as the mechanical property requirements and insulation requirements can be met. The application does not make specific limitations on their materials.

[0045] Preferably, the area of the alcohol glue 20 / the weight of the battery 10 ≥ 20 mm 2 / g to ensure the fixing effect of the battery 10. For example, the ratio of the area of the alcohol glue 20 to the weight of the battery 10 is 70 mm 2 / g, 75 mm 2 / g, 80 mm 2 / g, 85 mm 2 / g or 90 mm 2 / g, etc. If the weight of the battery 10 is heavier, the area of the alcohol glue 20 can be appropriately increased. In use, the area of the alcohol glue 20 can be made as close as possible to the area of the back of the battery 10 to improve the bonding effect between the battery 10 and the machine compartment.

[0046] In an alternative embodiment, as Figure 2 and Figure 3 shown, the alcohol glue 20 is divided into a plurality of alcohol glue monomers, and an alcohol flow channel 201 communicating with each other is provided between the plurality of alcohol glue monomers. The width of the alcohol flow channel is 0.5 mm - 3.5 mm.

[0047] It can be understood that dividing the alcohol glue 20 into a plurality of alcohol glue monomers and providing an alcohol channel communicating with each other between the plurality of alcohol glue monomers can improve the fluidity of alcohol between the alcohol glue monomers, thereby improving the dissolution effect of the alcohol glue 20 and facilitating the disassembly of the battery 10. The number of divisions of the alcohol glue 20 can be determined according to the size and weight of the battery 10. For example, the larger the size of the battery 10, the corresponding increase in the number of divisions of the alcohol glue 20; and / or the greater the weight of the battery 10, the corresponding increase in the number of divisions of the alcohol glue 20. However, the number of divisions of the alcohol glue 20 cannot be increased indefinitely. If the number of divided alcohol glue monomers is too large, it will not only increase the processing difficulty, but also reduce the viscosity of the alcohol glue 20 and affect the fixing effect of the battery 10. Optionally, the number of alcohol glue monomers is, for example, 4 - 16, 5 - 14, 6 - 12, 7 - 11 or 8 - 10, etc. The alcohol glue 20 can also be divided into other numbers of alcohol glue monomers according to the actual situation, and the present application does not make specific limitations on this.

[0048] The gaps between every two adjacent alcohol glue monomers communicate with each other to form an alcohol channel 201. Alcohol can flow to all alcohol glue monomers through the alcohol channel 201, thereby dissolving the alcohol glue 20. For example, alcohol can be dropped into the upper right corner of the alcohol glue 20, and then flow through the alcohol channel 201 to the periphery of each alcohol glue monomer to dissolve the alcohol glue monomer. In use, according to the specific structure between the battery fixing structure and the electronic device, other positions convenient for dropping can be selected to drop alcohol into the alcohol glue 20, not limited to dropping from the upper right corner of the alcohol glue 20.

[0049] The width of the alcohol flow channel 201 needs to be set within a reasonable range. If the width of the alcohol channel 201 is too narrow, the alcohol will not flow smoothly in the alcohol channel 201, resulting in the situation that some alcohol glue monomers cannot be dissolved; if the width of the alcohol channel 201 is too wide, it will cause insufficient pasting area of the alcohol glue 20 and affect the fixing effect of the battery 10. Optionally, the width of the alcohol channel 201 is, for example, 0.5 mm - 3.5 mm, 0.8 mm - 3.2 mm, 1.0 mm - 3.0 mm, 1.2 mm - 2.8 mm, 1.4 mm - 2.6 mm, 1.6 mm - 2.3 mm or 1.8 mm - 2.0 mm, etc. The width of the alcohol flow channel 201 can also be set to other appropriate sizes according to the actual situation, and the present application does not make specific limitations on this.

[0050] In an alternative embodiment, with continued reference to Figure 2 and Figure 3 , a plurality of alcohol glue monomers are evenly distributed on the back surface of the battery 10. The uniform arrangement of the plurality of alcohol glue monomers can improve the pasting effect between the battery 10 and the cabin. If the plurality of alcohol glue monomers are concentrated in a certain area on the back surface of the battery 10, it will cause the center of the alcohol glue 20 to deviate from the center of gravity of the battery 10, affecting the fixing effect of the battery 10. It can be understood that the shapes and / or sizes of the plurality of alcohol glue monomers can be the same or different. For example, Figure 2 or Figure 3 as shown in, the shapes of the alcohol glue monomers are all set to rectangles, and the size of the alcohol glue monomer in the upper right corner is smaller than that of other alcohol glue monomers, so that a space for alcohol to drip can be reserved in the upper right corner. The alcohol glue monomers can also be set to other shapes such as circles, squares, triangles, honeycombs or rhombuses. The size of the alcohol glue monomer at the corresponding position can also be appropriately reduced according to the dripping position of the alcohol. The present application does not make specific limitations on the shapes and sizes of the alcohol glue monomers.

[0051] In an alternative embodiment, the handle 30 includes a first portion located on the first surface, and the insulating tape 40 includes a second portion located on the first surface, and neither the first portion nor the second portion overlaps with the alcohol glue 20.

[0052] Specifically, as Figure 2 or Figure 3 shown, the handle 30 includes a first edge pasted on the front surface of the battery 10 and a second edge pasted on the back surface of the battery 10; the insulating tape 40 includes a first edge pasted on the front surface of the battery 10 and a second edge pasted on the back surface of the battery 10. On the back surface of the battery 10, there is a gap between the edge of the alcohol glue 20 close to the handle 30 and the second edge of the handle 30; there is a gap between the edge of the alcohol glue 20 close to the insulating tape 40 and the second edge of the insulating tape 40. In this way, the size of the battery fixing structure in the thickness direction will not be increased, and the battery capacity will not be adversely affected. The gap between the edge of the alcohol glue 20 and the edge of the handle 30 or the insulating tape 40 can be set between 1.0 mm and 10 mm, for example, 2 mm, 4 mm, 5 mm, 6 mm, 7 mm, 7.5 mm, 8 mm or 9 mm, etc. The gap can also be set to other sizes according to the situation, and the present application does not make specific limitations on it.

[0053] In an alternative embodiment, as Figure 2-4As shown, the lengths of the handle 30 and the insulating tape 40 are both less than the side length of the battery 10. Thus, a first uncovered area 101 will be formed on the side of the battery 10 close to the insulating tape 40, and a second uncovered area 102 will be formed on the side of the battery 10 close to the handle 30. At the positions of the first uncovered area 101 and the second uncovered area 102, more space can be reserved for an electronic device (such as a mobile phone), reducing the interference of the battery fixing structure on the electronic device and facilitating the installation and design of the electronic device.

[0054] In an alternative embodiment, as Figure 1 , 4 , as shown in Figure 5, the thickness at the bent portion 103 is less than the thickness of the battery 10. Thus, the bent portion 103 can not only reduce the dimensions of the battery 10 in the length and width directions, but also ensure that the bent portion 103 will not increase the overall thickness of the battery 10 and affect the energy density of the battery 10. In an alternative embodiment, several notches are provided on the portions of the handle 30 and / or the insulating tape 40 on the first surface and / or the second surface of the battery.

[0055] Specifically, notches can be provided on one or more of the first edge of the handle 30, the second edge of the handle 30, the first edge of the insulating tape 40, and the second edge of the insulating tape 40. For example Figure 2 , as shown, a second notch 401 is provided on the second edge of the insulating tape 40 adhered to the back surface of the battery 10 to avoid components such as protrusions provided on the electronic device at the corresponding position. For example Figure 4 , as shown, a first notch 301 is provided on the first edge of the handle 30 adhered to the front surface of the battery 10 to facilitate lifting or pulling out the battery from the electronic device. In application, the number and position of the notches can be adaptively adjusted according to the components of the electronic device to facilitate the installation of the electronic device, and the present application does not make specific limitations thereto.

[0056] In an alternative embodiment, as Figure 6 , as shown, the side of the battery 10 is bent twice towards the direction of the battery 10 to form a double-fold edge 104. Among them, the first bend forms a primary fold edge, and the second bend forms a secondary fold edge. The secondary fold edge is located between the battery 10 and the primary fold edge, so that the free end (the end with the exposed aluminum foil) of the side of the battery 10 is located between the battery 10 and the primary fold edge. That is, the exposed aluminum foil is wrapped in the space formed by the battery 10 and the primary fold edge. Therefore, even when the handle 30 and the insulating tape 40 do not completely cover the side of the battery 10, it can be avoided that the aluminum foil of the battery 10 comes into contact with an electronic device (such as a mobile phone housing) and causes a short circuit, ensuring the insulation of the battery 10.

[0057] The battery fixing structure of the present utility model omits the tear-off label in the existing battery fixing structure, correspondingly increasing the dimensions of the battery 10 in the thickness direction and the width direction, effectively improving the energy density of the battery 10. At the same time, the alcohol glue 20 is used to replace the double-sided adhesive in the prior art. When the battery 10 needs to be disassembled, the alcohol glue 20 is dissolved by alcohol, reducing the adhesion between the battery 10 and the electronic device. Thus, even without the tear-off label, the battery 10 can be conveniently disassembled only by using the handle 30 provided on the side of the battery 10.

[0058] In the specification provided herein, a number of specific details are set forth. It will be understood, however, that embodiments of the present utility model may be practiced without these specific details. In some instances, well-known methods, structures and techniques have not been shown in detail so as not to obscure an understanding of this description.

[0059] In addition, those of ordinary skill in the art will understand that although some embodiments described herein include some features included in other embodiments but not others, the combination of features of different embodiments means within the scope of the present utility model and forms different embodiments. For example, in the claims, any one of the claimed embodiments can be used in any combination.

[0060] Those skilled in the art should understand that although the present utility model has been described with reference to exemplary embodiments, various changes can be made and equivalents can be substituted for its elements without departing from the scope of the present utility model. In addition, many modifications can be made to adapt a particular situation or material to the teachings of the present utility model without departing from the essential scope thereof. Therefore, the present utility model is not limited to the specific embodiments disclosed, but the present utility model will include all embodiments falling within the scope of the appended claims.
