[0018] In order to make the purposes, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described below in connection with specific embodiments of the present application and corresponding drawings. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

[0019] The terms "first", "second", and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally a class, and are not limited to the number of objects, for example, the first object can be one or more.

[0020] The technical solutions disclosed in the various embodiments of the present application will be described in detail below in connection with the drawings.

[0021] Please refer to Figures 1 to 3 The battery fixing device disclosed in the embodiments of the present application can include a substrate 100 and a suction cup 200. The substrate 100 has a first surface 101 and a second surface 102 facing away from each other, which can be two surfaces of the substrate 100 along the thickness direction of the substrate 100. The first surface 101 of the substrate 100 is provided with an air hole 110, the substrate 100 has a certain thickness, and the inside of the substrate 100 is provided with an air channel 120 which is in communication with the air hole 110. The suction cup 200 is arranged on the first surface 101 of the substrate 100, and the suction cup 200 is provided with a suction cavity which is in communication with the air hole 110 and the air channel 120. The suction cup 200 can be fixed to the first surface 101 of the substrate 100 by adhesion, and the suction cup 200 is used to adsorb the battery 300. The second surface 102 of the substrate 100 can be attached to the surface of the equipment shell by glue or double-sided tape.

[0022] It should be noted that the equipment shell is the main bearing component of the electronic device, and the equipment shell is provided with a battery compartment for placing the battery 300. The second surface 102 of the substrate 100 can be attached to the surface of the battery compartment by glue or double-sided tape. In the actual installation process, the substrate 100 can be attached to the surface of the battery compartment first, then the battery 300 is placed on the substrate 100 and contacts the suction cup 200, a certain pressure is applied to the battery 300 and the suction cup 200 is extruded, so that the gas in the suction cup cavity is discharged, a negative pressure is generated in the inside of the suction cup cavity, and the adsorption of the battery 300 is realized, so that the battery 300 is fixed in the battery compartment of the equipment shell.

[0023] The air passage 120 is provided with a port 121 which is in communication with the outside. When the port 121 is in a closed state, the part of the suction cup 200 in contact with the battery 300 (suction cup cavity) can form a negative pressure to achieve the suction and fixation of the battery 300. When the port 121 is in an open state, the suction cup cavity can be in communication with the outside through the air passage 120 to release the negative pressure state of the suction cup cavity, so that the suction cup 200 can be separated from the battery 300, and then the battery 300 can be taken out of the battery compartment of the equipment shell.

[0024] The control mode of the port 121 when switching between the open state and the closed state can include: one is to provide a sealing plug at the port 121, and when the sealing plug blocks the port 121, the port 121 is in the closed state, and when the sealing plug is separated from the port 121, the port 121 is in the open state; the other is to provide a valve body at the port 121, and the opening and closing of the valve body can also achieve the switching of the port 121 between the open state and the closed state. In addition to the above two control modes, other structures can also be used to control the opening and closing of the port 121, which is not limited in the embodiments of the present application.

[0025] As described above, the battery fixing device disclosed in the embodiments of the present application improves the related art. By using the combination scheme of the substrate 100 and the suction cup 200, when the port 121 of the air passage 120 is in the closed state, the part of the suction cup 200 in contact with the battery 300 can form a negative pressure by extruding the gas, so as to adsorb the battery 300 and stably assemble the battery 300 in the equipment shell. When the battery 300 needs to be disassembled, the port 121 can be controlled to be in the open state, the suction cup 200 can be in communication with the outside through the air passage 120, the suction cup 200 can release the suction force and separate from the battery 300, and then the battery 300 can be easily taken out of the equipment shell without the need for forced disassembly, thereby reducing the probability of damage and scrapping of the battery 300.

[0026] Considering the thin and light design of electronic equipment, the thickness of the substrate 100 should be as small as possible. In an optional embodiment of the present application, as shown in Figures 1 to 3 The substrate 100 can be designed as a film layer. Specifically, the substrate 100 can include a first film layer 130, a connecting layer 140 and a second film layer 150 which are sequentially stacked. The materials of the first film layer 130 and the second film layer 150 can be the same, such as PET (Polyethylene terephthalate, thermoplastic polyester), PVC (Polyvinyl chloride, polyvinyl chloride) and the like. The first film layer 130 and the second film layer 150 are connected through the connecting layer 140.

[0027] The surface of the first film layer 130 away from the connecting layer 140 is the first surface 101, and the surface of the second film layer 150 away from the connecting layer 140 is the second surface 102. The connecting layer 140 can include a first adhesive area 141, a second adhesive area 142, and a glue-free area 143. The first adhesive area 141 and the second adhesive area 142 are arranged outside the glue-free area 143. Since the glue layers of the first adhesive area 141 and the second adhesive area 142 have a certain thickness, the glue-free area 143 can form the air channel 120. The second adhesive area 142 surrounds the port 121 of the air channel 120. In other words, the port 121 of the air channel 120 extends into the second adhesive area 142. It can be understood that when the second adhesive area 142 is in an adhesive state with the first film layer 130 and the second film layer 150, the port 121 of the air channel 120 is closed by the second adhesive area 142. When the second adhesive area 142 is separated from at least one of the first film layer 130 and the second film layer 150, the port 121 of the air channel 120 is in an open state and can communicate with the outside.

[0028] Based on the above, when the first adhesive area 141 and the second adhesive area 142 are respectively adhered to the first film layer 130 and the second film layer 150, the port 121 of the air channel 120 is in a closed state. At this time, part of the gas in the suction cup cavity can be squeezed out and form a negative pressure, so as to adsorb the battery 300, so that the battery 300 is stably assembled in the equipment shell. When the second adhesive area 142 is separated from at least one of the first film layer 130 and the second film layer 150, the port 121 of the air channel 120 can be in an open state. At this time, the suction cup 200 can communicate with the outside through the air channel 120, and the suction cup 200 can release the suction force and separate from the battery 300, so that the battery 300 can be easily taken out of the equipment shell. It can be understood that the first film layer 130 or the second film layer 150 can be separated from the second adhesive area 142 by tearing the first film layer 130 or the second film layer 150, so as to realize the opening of the port 121.

[0029] It should be noted that when the port 121 is in a closed state, the air pressure in the suction cup cavity and the air pressure in the air channel 120 are in a balanced state and are less than the atmospheric pressure. Therefore, the atmospheric pressure can press the regions of the first film layer 130 and the second film layer 150 close to the air channel 120 towards the connecting layer 140, so as to improve the stability of the adhesion between the first film layer 130 and the connecting layer 140 and the second film layer 150 and the connecting layer 140, thereby avoiding the problem that the battery 300 falls off the suction cup 200 due to air leakage.

[0030] As Figures 1 to 3As shown, the first film layer 130 can include a first main body 131 and a first pulling portion 132 extended by the edge of the first main body 131, the second film layer 150 can include a second main body 151 and a second pulling portion 152 extended by the edge of the second main body 151, the first main body 131 is arranged opposite to the second main body 151, and the first pulling portion 132 is arranged opposite to the second pulling portion 152. The opposite surfaces of the first adhesive area 141 can be respectively bonded with the first main body 131 and the second main body 151, and the opposite surfaces of the second adhesive area 142 can be respectively bonded with the first pulling portion 132 and the second pulling portion 152. The air channel 120 can be linear, the air channel 120 is arranged extending from the first adhesive area 141, and the port 121 of the air channel 120 extends to the second adhesive area 142, and in the case that the second adhesive area 142 is separated from at least one of the first pulling portion 132 and the second pulling portion 152, the port 121 can be in an open state.

[0031] By arranging the first pulling portion 132 and the second pulling portion 152, the operation is facilitated, and the operator can easily switch the port 121 to the open state through the first pulling portion 132 and the second pulling portion 152, so as to facilitate the subsequent battery 300 dismounting step.

[0032] As shown, Figure 3 The second adhesive area 142 can include a first sub-area 1421 and a second sub-area 1422, the first sub-area 1421 is close to the first adhesive area 141, the second sub-area 1422 is away from the first adhesive area 141, and the port 121 of the air channel 120 extends to the second sub-area 1422. The first adhesive area 141 and the first sub-area 1421 are both strong adhesive areas, and the second sub-area 1422 is a weak adhesive area, that is, the adhesive force of the first adhesive area 141 and the first sub-area 1421 is greater than that of the second sub-area 1422. By adopting the design of strong adhesive area and weak adhesive area, on the one hand, the sealing property of the air channel 120 can be ensured when the suction cup 200 adsorbs the battery 300, and on the other hand, when the battery 300 needs to be dismounted, the first pulling portion 132 or the second pulling portion 152 can be easily pulled away from the weak adhesive area, so that the port 121 of the air channel 120 is in an open state.

[0033] In the case that the first pulling portion 132 or the second pulling portion 152 rubs against the equipment shell, the port 121 may be mistakenly opened, based on the above problem, as shown, Figure 3 A narrowing structure 122 can be arranged at the edge of the port 121 close to the second sub-area 1422, by arranging the narrowing structure 122, the port 121 will not be opened in the case that the opening degree of the first pulling portion 132 or the second pulling portion 152 is not large, which can reduce the probability of the port 121 being mistakenly opened.

[0034] As shown in Figure 2 , the first pulling part 132 is provided with a first extension part 133 away from the edge of the first main body part 131, the second pulling part 152 is provided with a second extension part 153 away from the edge of the second main body part 151, and the first extension part 133 and the second extension part 153 are not provided with an adhesive layer. The operator can easily tear the first pulling part 132 or the second pulling part 152 from the second adhesive area 142 by tearing the first extension part 133 or the second extension part 153.

[0035] In addition, in order to facilitate the operator to distinguish, at least one of the first extension part 133 and the second extension part 153 is provided with a pull-easy mark, which can be a paper label, a colored coating, etc. The operator can quickly locate the position of the first extension part 133 and the second extension part 153 through the pull-easy mark, so as to improve the operation efficiency.

[0036] As shown in Figure 3 , the air channel 120 can include an air channel body 123 and an ear part 124. The air channel body 123 is linearly distributed, and the ear part 124 is protrudingly and extendingly arranged from the side edge of the air channel body 123. The ear part 124 is in communication with the air channel body 123, and the air hole 110 is in communication with the ear part 124. By arranging the ear part 124, the mounting position of the suction cup 200 can be flexibly adjusted, thereby improving the flexibility of the battery 300 installation.

[0037] In an optional embodiment of the present application, as shown in Figure 1 , the battery fixing device includes at least two suction cups 200, and the first surface 101 of the substrate 100 is provided with at least two air holes 110. The suction cup 200 is in communication with the air hole 110. In actual installation process, the more the number of suction cups 200 is, the more stable the adsorption of the battery 300 is, as long as the space allows. For example, two air holes 110 can be arranged on the first surface 101 of the substrate 100, and correspondingly, the number of suction cups 200 is also two. It should be noted that, in the direction perpendicular to the surface of the substrate 100, the size of the air channel 120 can be 0.2mm-0.5mm, such as 0.2mm, 0.3mm, 0.4mm, 0.5mm, etc.

The air channel 120 is provided with a port 121 in communication with the outside, when the port 121 is in a closed state, the part of the suction cup 200 in contact with the battery 300 can form a negative pressure after the gas is extruded by extrusion, so that the battery 300 can be adsorbed, and the battery 300 can be stably assembled in the device shell; when the battery 300 needs to be disassembled, the port 121 can be controlled to be in an open state, the suction cup 200 can be in communication with the outside through the air channel 120, the suction cup 200 can release the suction force and be separated from the battery 300, and then the battery 300 can be easily taken out from the device shell without the need of forcibly disassembling the battery 300, so that the probability of damage and scrapping of the battery 300 is reduced.
