The mounting frame is formed with a battery compartment, the steel-shell battery 10 is accommodated in the battery compartment and connected to the mounting frame through the elastic component 20. The elastic component 20 is configured to be perpendicular to the thickness direction ( Figure 1 In a plane (Z direction in the figure), the steel shell battery 10 can elastically float relative to the mounting frame through the elastic component 20.

[0032] According to the above description, the steel shell battery 10 is no longer fixedly connected to the mounting frame by double-sided tape, but is connected by an elastic component 20, so that the two can float elastically, which not only meets the installation requirements of the steel shell battery 10, but also can absorb the impact during the floating process through the elastic component 20, thereby avoiding damage, fire, explosion and the like caused by unreliable fixation of the steel shell battery 10, and improving the installation reliability and use safety of the steel shell battery 10.

[0033] The present application does not limit the specific implementation of the elastic component 20. In one embodiment, Figure 3 and Figure 4 As shown, the elastic component 20 can be a tension spring and / or a compression spring. Figure 1 The posture shown in the figure is placed in the battery compartment, one end of the tension spring and / or compression spring is in contact with the steel shell battery 10, and the other end is released from the mounting frame, so that the steel shell battery 10 can be elastically floated in a plane A perpendicular to the thickness direction of the steel shell battery 10. Figure 3 The compression springs shown in the figure are respectively arranged on two opposite sides 101 of the steel shell battery 10, so as to realize elastic floating of the steel shell battery 10 in the X direction within the plane A. The number of compression springs is not limited, and the minimum number is one. Figure 4 The tension springs shown are respectively arranged on the top surface or the bottom surface of the steel shell battery 10, so as to realize elastic floating of the steel shell battery 10 in the Y direction in the plane A. The number of tension springs is not limited, and the minimum number is one.

[0034] In this embodiment, Figure 2 As shown, the elastic component 20 includes a first part 21 and a second part 22, one of which is provided on the steel shell battery 10, and the other is provided on the mounting frame. For example, the first part 21 is provided on the steel shell battery 10, and the second part 22 is provided on the mounting frame. For another example, the first part 21 is provided on the mounting frame, and the second part 22 is provided on the steel shell battery 10. The first part 21 and the second part 22 are detachably connected, and the connection between the first part 21 and the second part 22 is elastic, so that the steel shell battery 10 is elastically floated in the plane A. In this scheme, the first part 21 and the second part 22 are detachable, which facilitates the disassembly of the steel shell battery 10, realizes the maintenance and replacement of the steel shell battery 10, and improves the reuse rate of the steel shell battery 10. In addition, by elastically connecting the first part 21 and the second part 22, the elastic floating of the steel shell battery 10 relative to the mounting frame can be realized, and the structure is simple and convenient to set up.

[0035] In one embodiment, Figure 5 As shown, the first part 21 and the second part 22 are arranged opposite to each other, and at least one of the first part 21 and the second part 22 can be made of an elastic material, including but not limited to silicone. For example, the first part 21 is made of an elastic material, and the first part 21 can be compressed and deformed when subjected to the abutment force of the second part 22. Alternatively, the second part 22 is made of an elastic material, and the second part 22 can be compressed and deformed when subjected to the abutment force of the first part 21. Alternatively, both the first part 21 and the second part 22 are made of an elastic material, and both can be compressed and deformed when abutting against each other, thereby realizing the elastic floating of the steel shell battery 10 in the X direction.

[0037] In this embodiment, Figure 2 As shown, the first part 21 includes a first protrusion 210, and the first protrusion 210 can protrude in a direction parallel to the floating plane (plane A) of the steel shell battery 10 and protrude toward the second part, but is not limited to this. The second part 22 includes a second protrusion 220 and a third protrusion 221, and the second protrusion 220 and the third protrusion 221 can protrude in parallel along the thickness direction of the steel shell battery 10, but are not limited to this. A gap 222 is provided between the second protrusion 220 and the third protrusion 221, and the first protrusion 210 is provided in the gap 222 and is clamped between the second protrusion 220 and the third protrusion 221, and the direction of the clamping force is parallel to the floating plane of the steel shell battery 10, and at least one of the second protrusion 220 and the third protrusion 221 is in elastic contact with the first protrusion 210. In this way, the movement of the steel-shell battery 10 in the thickness direction is reduced or even avoided by clamping the first protrusion 210. At the same time, the elastic floating of the steel-shell battery 10 relative to the mounting frame in the plane A can also be satisfied.

[0038] In one embodiment, the first protrusion 210 is provided on the side 101 of the steel shell battery 10, and the first protrusion 210 can protrude in a direction parallel to the floating plane of the steel shell battery 10. The first protrusion 210 can be welded or integrally formed with the outer shell of the steel shell battery 10. The second protrusion 220 and the third protrusion 221 are provided on the mounting frame, and the second protrusion 220 and the third protrusion 221 protrude in parallel along the thickness direction of the steel shell battery 10. The second protrusion 220 and the third protrusion 221 can be fixed to the mounting frame by bolts, adhesive, and buckles.

[0039] In some other embodiments, the first protrusion 210 is provided on the mounting frame, and the first protrusion 210 may protrude along the thickness direction of the steel shell battery 10, and the second protrusion 220 and the third protrusion 221 are provided on the side 101 of the steel shell battery 10, and protrude in parallel in a direction parallel to the floating plane of the steel shell battery 10. Of course, the first protrusion 210, the second protrusion 220 and the third protrusion 221 may all protrude in parallel in a direction parallel to the floating plane of the steel shell battery 10, and the second protrusion 220 and the third protrusion 221 protrude in parallel, facing and parallel to the protrusion direction of the first protrusion 210.

[0040] In this embodiment, in order to facilitate assembly, the first part 21 may further include a first bottom plate 211, the first protrusion 210 is provided on the first bottom plate 211, the first part 21 is connected to the steel-shell battery 10 through the first bottom plate 211, and the first protrusion 210 and the first bottom plate 211 may be integrally formed. The second part 22 may further include a second bottom plate 223, the second protrusion 220 and the third protrusion 221 are provided on the second bottom plate 223, and the second part 22 is connected to the steel-shell battery 10 through the second bottom plate 223. The second bottom plate 223 may be integrally formed with the second protrusion 220 and the third protrusion 221.

[0041] Please refer to Figure 7 , Figure 7 for Figure 2 An exploded view of the second part 22 is shown in FIG.

[0042] In one embodiment, at least one of the second protrusion 220 and the third protrusion 221 is configured as an elastic protrusion 23, and the elastic protrusion 23 includes a protrusion body 230 and an elastic part 231. The elastic part 231 is capable of stretching and deforming in the clamping direction. One end of the elastic part 231 in the stretching direction is relatively fixed to the protrusion body 230, and the other end in the stretching direction is in contact with the first protrusion 210. In this solution, the protrusion body 230 is non-deformable, and the elastic part 231 is deformable. The elastic part 231 is arranged on the protrusion body 230, and elastically abuts against the first protrusion 210, so that the second protrusion 220 and the third protrusion 221 can elastically clamp the first protrusion 210, and then the first protrusion 210 can float in the stretching direction of the elastic part 231, and the structure is stable and reliable. The elastic part 231 includes but is not limited to a compression spring or a compressible elastic colloid, and the compression spring or elastic colloid provides a clamping force to the first protrusion 210.

[0043] In one embodiment, the protruding portion body 230 is provided with a receiving cavity 2300 extending along the telescopic direction of the elastic portion 231, and the elastic portion 231 includes an elastic compression member 2310 received in the receiving cavity 2300, and the elastic compression member 2310 is used to apply an elastic clamping force to the first protruding portion 210. The receiving cavity 2300 can prevent the elastic compression member 2310 from tipping over when applying the clamping force to the first protruding portion 210, thereby improving the stability of the elastic compression member 2310 during compression deformation. The elastic compression member 2310 can be a compression spring.

[0044] In one embodiment, the elastic part 231 further includes a sphere 2311, the elastic compression member 2310 is received in the receiving cavity 2300, the sphere 2311 is disposed at one end of the elastic compression member 2310 close to the first protruding portion 210, most of the sphere 2311 is disposed in the receiving cavity 2300, and a small portion is disposed outside the receiving cavity 2300, the diameter of the sphere 2311 is larger than the diameter of the receiving cavity 2300, the portion of the sphere 2311 located in the receiving cavity 2300 abuts against the elastic compression member 2310, and the portion located outside the receiving cavity 2300 abuts against the first protruding portion 210. In this solution, the sphere 2311 contacts the first protruding portion 210 through the spherical surface, which can reduce the phenomenon that the elastic compression member 2310 cannot reliably contact the first protruding portion 210 due to the processing error of the surface of the first protruding portion 210. On the other hand, the sphere 2311 can also roll relative to the protrusion body 230, which can reduce the difficulty of inserting the first protrusion 210 into the gap 222. In this embodiment, the second protrusion 220 and the third protrusion 221 are both configured as elastic protrusions 23, and the steel shell battery 10 can elastically float toward the side close to the second protrusion 220, and can elastically float toward the side close to the third protrusion 221.

[0045] In one embodiment, the elastic protrusion 23 further includes a stopper 232 disposed in the receiving cavity 2300, and one end of the elastic compression member 2310 away from the sphere 2311 contacts the stopper 232. In the telescopic direction, the position of the stopper 232 is adjustable, so that the elastic clamping force applied by the elastic compression member 2310 to the first protrusion 210 is adjustable. In other words, the initial compression amount of the elastic compression member 2310 and the initial pre-tightening force of the elastic compression member 2310 after installation can be adjusted through the stopper 232, and then the clamping force applied by the elastic compression member 2310 to the first protrusion 210 can be adjusted.

[0046] In one embodiment, Figure 2 As shown, the side surface 2100 of the first protrusion 210 in contact with the sphere 2311 is set as an arc-shaped concave surface. The arc-shaped concave surface can increase the contact area between the sphere 2311 and the first protrusion 210, and increase the stability of the clamping structure.

[0047] In one embodiment, the first protrusion 210 includes an insertion end 2101 inserted into the gap 222, and the cross-sectional area of ​​the insertion end 2101 gradually decreases along the insertion direction. In other words, the first protrusion 210 has a non-uniform cross-sectional structure, with a large front end and a small rear end, which can increase the resistance of the first protrusion 210 to escape from the gap 222 and increase the reliability of clamping.

[0048] In one embodiment, the elastic components 20 are provided in multiple groups, and the multiple groups of the elastic components 20 are configured to enable the steel shell battery 10 to move in multiple directions within the activity plane. For example, the steel shell battery 10 can move in the X direction and the Y direction respectively.

[0049] In a specific embodiment, the steel shell battery 10 is in a square shape, and the elastic components 20 are respectively provided on two opposite sides in the length direction of the steel shell battery 10, so that the steel shell battery 10 can elastically float along the width direction (X direction). Alternatively, the elastic components 20 are respectively provided on two opposite sides in the width direction of the steel shell battery 10, so that the steel shell battery 10 can elastically float along the length direction (Y direction). For another example, the elastic components 20 are provided on both the opposite sides in the length direction and the opposite sides in the width direction of the steel shell battery 10, so that the steel shell battery 10 can elastically float along the width direction and the length direction.

[0050] In another embodiment, the steel shell battery 10 is circular in shape. In this case, elastic components 20 can be respectively provided at both ends of two mutually perpendicular diameter directions of the steel shell battery 10, thereby realizing elastic floating of the steel shell battery 10 in two mutually perpendicular diameter directions.

[0051] In one embodiment, the mounting frame is provided with a groove that is recessed toward the periphery of the battery compartment, and the elastic component 20 is located in the groove. In this way, the elastic component 20 does not occupy the space of the battery compartment, which is conducive to improving the energy density of the steel shell battery 10. In addition, the steel shell battery 10 no longer uses double-sided tape, which saves space in the thickness direction of the steel shell battery 10, and the space can also be used to increase the capacity of the steel shell battery 10.

[0052] The present application also provides an electronic device, which includes the steel shell battery fixing structure 100 described above, and the electronic device includes but is not limited to a mobile phone and a mobile terminal.

[0053] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
