[0037] See also Figures 1 to 9 As shown, according to an embodiment of the present application, an electronic device is provided, which includes a battery fixing structure, wherein the battery fixing structure includes a mounting body 10 and a battery 20.

[0038] The mounting body 10 includes a first mounting plate 11 and a second mounting plate 12 which are stacked, and the first mounting plate 11 is fixedly connected to the second mounting plate 12. The battery 20 is arranged between the first mounting plate 11 and the second mounting plate 12, and a plurality of limiting grooves 111 are arranged on the first mounting plate 11. The battery 20 has at least two opposite side walls, and a plurality of limiting protrusions 201 are arranged at intervals on at least two opposite side walls of the battery 20. The plurality of limiting protrusions 201 are inserted into the plurality of limiting grooves 111 in a one-to-one correspondence along the stacking direction of the first mounting plate 11 and the second mounting plate 12. A stopper 121 is arranged on the surface of the second mounting plate 12 close to the first mounting plate 11, and the stopper 121 abuts against the limiting protrusion 201 along the stacking direction of the first mounting plate 11 and the second mounting plate 12.

[0039] Specifically, the electronic device of this embodiment can be, for example, a laptop or a mobile phone, the first mounting plate 11 of the mounting body 10 is usually a plate in the laptop or mobile phone for mounting the battery 20, and the second mounting plate 12 is usually a back cover of the laptop or mobile phone. In addition, the second mounting plate 12 and the first mounting plate 11 can be fixedly connected by screws, or by magnetic attraction, or of course, by snap-on connection.

[0040] Compared with the prior art, in the present embodiment, a plurality of limiting protrusions 201 are arranged on at least two opposite side walls of the battery 20, and a plurality of limiting grooves 111 are arranged on the first mounting plate 11. The plurality of limiting protrusions 201 are inserted into the plurality of limiting grooves 111 one by one along the stacking direction of the first mounting plate 11 and the second mounting plate 12, so that the first mounting plate 11 can limit the battery 20 in a plane perpendicular to the stacking direction of the first mounting plate 11 and the second mounting plate 12. At the same time, a stopper 121 is provided on the second mounting plate 12, and the stopper 121 abuts against the limiting protrusion 201 along the stacking direction of the first mounting plate 11 and the second mounting plate 12, that is, when the second mounting plate 12 is fixedly connected to the first mounting plate 11, the stopper 121 applies a force along the direction of the second mounting plate 12 approaching the first mounting plate 11 to the limiting protrusion 201, so that the limiting protrusion 201 is limited in the limiting groove 111, thereby preventing the battery 20 from being separated from the first mounting plate 11. The structure of this embodiment does not need to open a threaded hole on the battery 20, nor does it need to use screws to fix the battery 20 on the first mounting plate 11. The battery 20 can be fixed on the installation body 10 only by the cooperation of the limiting groove 111, the limiting protrusion 201 and the stopper 121. The structure is simple and saves time and effort during assembly.

[0041] Furthermore, the battery 20 includes a first side wall 21 and a second side wall 22 that are arranged opposite to each other; the limiting protrusions 201 include four, two of which are arranged on the first side wall 21 at intervals, and the remaining two of which are arranged on the second side wall 22 at intervals.

[0042] Specifically, in this embodiment, the limiting groove 111 is arranged on the outside of the first side wall 21 and the second side wall 22, the limiting protrusion 201 arranged on the first side wall 21 protrudes in the direction away from the first side wall 21, and the limiting protrusion 201 arranged on the second side wall 22 protrudes in the direction away from the second side wall 22, and the side wall of the limiting groove 111 is provided with an escape opening for the limiting protrusion 201 to penetrate, so as to avoid the limiting protrusion 201 from interfering with the side wall surface of the limiting groove 111. In this embodiment, two limiting protrusions 201 are respectively arranged on the first side wall 21 and the second side wall 22, so that the battery 20 can be limited in the plane perpendicular to the first mounting plate 11 and the second mounting plate 12, so as to avoid the battery 20 from moving freely in the plane when subjected to external force. At the same time, two limiting protrusions 201 are provided on the first side wall 21 and two limiting protrusions 201 are provided on the second side wall 22 to increase the fixing points of the battery 20 and the first mounting plate 11 , so that the first mounting plate 11 can better limit the battery 20 .

[0043] Of course, in some embodiments, the battery 20 is a rectangular battery 20, and the battery 20 also includes a third side wall and a fourth side wall that are relatively arranged, and a limiting protrusion 201 is provided on the third side wall and the fourth side wall. The first mounting plate 11 is provided with a limiting groove 111 for cooperating with the limiting protrusion 201 at a position relative to the third side wall and the fourth side wall, so as to better limit the battery 20 and prevent the first mounting plate 11 from being unable to limit the battery 20 after part of the limiting groove 111 is damaged.

[0044] As attached Figure 8 As shown, the first mounting plate 11 is connected with a first stop segment 112, a second stop segment 113 and a third stop segment 114, the first stop segment 112 and the second stop segment 113 are spaced apart in a direction perpendicular to two opposite side walls of the battery 20 from one side wall to the other side wall, the third stop segment 114 is connected between the first stop segment 112 and the second stop segment 113, and the first stop segment 112, the second stop segment 113 and the third stop segment 114 are surrounded to form a limiting groove 111.

[0045] Specifically, the first stop segment 112, the second stop segment 113 and the third stop segment 114 are arranged on the first mounting plate 11 close to the side of the limiting protrusion 201, and the limiting groove 111 formed by the first stop segment 112, the second stop segment 113 and the third stop segment 114 has a first opening 31 and a second opening 32, the opening direction of the first opening 31 is consistent with the protruding direction of the limiting protrusion 201, and the opening direction of the second opening 32 is consistent with the stacking direction. The first opening 31 is an avoidance opening, and the second opening 32 is used to enable each limiting protrusion 201 to be inserted into the limiting groove 111 in the stacking direction, and the stop portion 121 can be inserted into the limiting groove 111 through the second opening 32 and abut against the limiting protrusion 201.

[0046] When the limiting protrusion 201 is inserted into the limiting groove 111, in order to prevent a large difference in size between the limiting protrusion 201 and the limiting groove 111, which may cause the limiting protrusion 201 to shake in the limiting groove 111, in this embodiment, the limiting protrusion 201 is pressed against the first stop section 112, the second stop section 113 and the third stop section 114, that is, after the limiting protrusion 201 is inserted into the limiting groove 111, there is almost no gap between the limiting protrusion and the first stop section 112, the second stop section 113 and the third stop section 114, so that the limiting protrusion 201 can be respectively subjected to the supporting force applied by the first stop section 112, the second stop section 113 and the third stop section 114, thereby preventing the limiting protrusion 201 from shaking in the limiting groove 111 due to the action of external force.

[0047] As attached Fig. 9 As shown, when the stop portion 121 is inserted into the limiting groove 111 and abuts against the limiting protrusion 201, if there is a large gap between the stop portion 121 and the third stop section 114 or between the stop portion 121 and the side wall of the battery 20, the stop portion 121 may be damaged or offset when the battery 20 is subjected to external force, thereby causing the stop portion 121 to be unable to abut against the limiting protrusion 201. Therefore, in this embodiment, the side walls of the stop portion 121 respectively abut against the third stop segment 114 and the side walls of the battery 20, that is, the size of the gap between the stop portion 121 and the third stop segment 114 and the gap between the stop portion 121 and the side wall of the battery 20 is almost zero, so that when the stop portion 121 abuts against the limiting protrusion 201, the third stop segment 114 and the side wall of the battery 20 can exert a supporting force on the stop portion 121, thereby improving the stability of the stop portion 121.

[0048] Furthermore, chamfers are provided at the connection points of the inner wall surfaces of the limiting groove 111 (not shown in the figure).

[0049] Specifically, chamfers are provided at the connection of each inner wall surface of the limiting groove 111, that is, chamfers are provided between the first stop section 112 and the second stop section 113, the third stop section 114 and the second stop section 113, the first stop section 112 and the first mounting plate 11, the second stop section 113 and the first mounting plate 11, and the third stop section 114 and the first mounting plate 11, so as to make the corner area of ​​the limiting groove 111 smoother and avoid interference between the limiting protrusion 201 and the inner wall surface or the bottom surface of the limiting groove 111 when the limiting protrusion 201 is inserted into the limiting groove 111. Optionally, a chamfer is also provided on the limiting protrusion 201.

[0050] Further, the stopper 121 includes at least one of a rectangular column and a circular column.

[0051] Specifically, when the stopper 121 is set as a cylinder, the limiting groove 111 can be set as an arc-shaped groove to reduce the friction between the stopper 121 and the arc-shaped groove. When the stopper 121 is set as a rectangular column, since the limiting groove 111 is chamfered, the friction between the edge of the rectangular column and the limiting groove 111 can be reduced, thereby improving the structural stability of the stopper 121.

[0052] As attached Figure 2 As shown, a protective portion 122 is provided on the surface of the second mounting plate 12 close to the first mounting plate 11, and the protective portion 122 abuts against the first mounting plate 11. Specifically, the protective portion 122 of this embodiment is used to prevent other structures in the electrical device from entering the battery fixing structure, thereby affecting the battery 20. In addition, when the limiting groove 111, the limiting protrusion 201 or the stopper 121 is damaged, the battery 20 cannot be fixed on the first mounting plate 11, and the protective portion 122 can limit the movement of the battery 20 to a certain extent, thereby preventing the battery 20 from passing through the battery fixing structure and entering other areas of the electronic device, thereby affecting other components of the electronic device.

[0053] As attached Figure 4 As shown, the second mounting plate 12 is a rectangular plate, and the protection portion 122 includes a first extension section 1221, a second extension section 1222, and a third extension section 1223. The first extension section 1221 is connected to the first side of the second mounting plate 12, and the first extension section 1221 extends in a direction close to the first mounting plate 11 and abuts against the first mounting plate 11. The second extension section 1222 is connected to the second side of the second mounting plate 12, and the second extension section 1222 extends in a direction close to the first mounting plate 11 and abuts against the first mounting plate 11. The third extension section 1223 is connected to the third side of the second mounting plate 12, and is connected between the first extension section 1221 and the second extension section 1222, and the third extension section 1223 extends in a direction close to the first mounting plate 11 and abuts against the first mounting plate 11.

[0054] In this embodiment, the first extension section 1221, the second extension section 1222 and the third extension section 1223 are arranged to form a protective portion 122 to prevent the battery 20 from moving out of the battery fixing structure from the first side, the second side and the third side of the second mounting plate 12. In addition, the second mounting plate 12 also has a fourth side, and a third opening 33 is formed between the fourth side and the first mounting plate 11. The third opening 33 is used for a power connection line (not shown in the figure) to pass through and connect with the battery 20.

[0055] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0056] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0057] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
