[0035] See also Figures 1 to 6 As shown, according to an embodiment of the present application, an electronic device is provided, which may be, for example, a notebook computer or a mobile phone. The electronic device includes a battery fixing structure, which includes a mounting body 10 and a battery 20 .

[0036] The installation body includes a first installation plate 11 and a second installation plate 12 which are stacked, the first installation plate 11 is fixedly connected to the second installation plate 12, the battery 20 is arranged between the first installation plate 11 and the second installation plate 12, a plurality of limiting protrusions 201 are arranged on the side wall of the battery 20, a plurality of limiting grooves 111 are arranged on the surface of the first installation plate 11 close to the second installation plate 12, the groove direction of the limiting grooves 111 is consistent with the first direction, and the plurality of limiting protrusions 201 are inserted into the plurality of limiting grooves 111 one by one. A recessed portion 2011 is arranged on one of the limiting protrusions 201 and the limiting grooves 111, and a protruding portion 1111 is arranged on the other of the limiting protrusions 201 and the protruding portion 1111 abuts against the recessed portion 2011.

[0037] Specifically, the battery 20 and the first mounting plate 11 are connected by a plurality of limiting protrusions 201 and a plurality of limiting grooves 111. At the same time, a protrusion 1111 is provided on one of the limiting grooves 111 and the limiting protrusion 201, and a recessed portion 2011 is provided on the other, so that when the limiting protrusion 201 is inserted into the limiting groove 111, the protrusion 1111 abuts against the recessed portion 2011, thereby preventing the limiting protrusion 201 from separating from the limiting groove 111 when the battery 20 is subjected to a small external force, and eventually causing the battery 20 to detach from the mounting body 10. In addition, the slotting direction of the limiting groove 111 refers to the direction from the slot opening of the limiting groove 111 to the bottom of the groove. In this embodiment, the first direction (as shown in the attached figure) is the direction from the slot opening of the limiting groove 111 to the bottom of the groove. Figure 1 The X direction in the middle is the length direction of the first mounting plate 11, which means that when assembling the battery 20 with the first mounting plate 11, it only needs to apply an external force consistent with the first direction to the battery 20, so that the multiple limiting protrusions 201 can be inserted into the multiple limiting grooves 111 one by one, thereby improving the assembly efficiency of the battery 20 and the first mounting plate 11.

[0038] In this embodiment, the first mounting plate 11 is a mounting plate for mounting batteries in the electronic device, and the second mounting plate 12 is the outer shell of the electronic device, that is, the first mounting plate 11 is equivalent to the mounting plate for mounting batteries 20 in a laptop computer or a mobile phone, and the second mounting plate 12 is equivalent to the outer shell of the laptop computer or the mobile phone. The second mounting plate 12 can usually be fixedly connected to the first mounting plate 11 by screws, magnets or snap-ons.

[0039] Compared with the prior art, the present embodiment is provided with a plurality of limiting protrusions 201 on the side wall of the battery 20, a plurality of limiting grooves 111 are provided on the surface of the first mounting plate 11 close to the second mounting plate 12, and a recessed portion 2011 is provided on one of the limiting protrusions 201 and the limiting grooves 111, and a protruding portion 1111 is provided on the other of the limiting protrusions 201 and the limiting grooves 111, so that when the limiting protrusions 201 are inserted into the limiting grooves 111, the protruding portions 1111 can apply a resisting force to the recessed portions 2011, so that the battery 20 can be fixed on the first mounting plate 11. In the battery fixing structure of the present embodiment, when the battery 20 is connected to the mounting body 10, there is no need to open a screw hole on the battery 20, nor is there a need to connect the battery 20 to the mounting body 10 by screws, thereby reducing the manufacturing cost of the battery fixing structure to a certain extent, and the matching mode of the limiting grooves 111 and the limiting protrusions 201 enables the battery 20 to be quickly assembled with the mounting body 10.

[0040] Further, the recessed portion 2011 is disposed on the limiting protrusion 201 , and the recessed portion 2011 includes an arc-shaped groove; the protruding portion 1111 is disposed in the limiting groove 111 , and the protruding portion 1111 includes an arc-shaped protrusion adapted to the arc-shaped groove.

[0041] Specifically, when the battery 20 is fixed on the installation body 10, an external force is first applied to the battery 20 so that the limiting protrusion 201 is inserted into the limiting groove 111. Since the limiting protrusion 201 is provided with a recessed portion 2011, and the limiting groove 1111 is provided with a protruding portion 1111, when the protruding portion 1111 and the recessed portion 2011 have edges and corners, the friction between the limiting groove 111 and the limiting protrusion 201 is too large, which may eventually cause damage to the battery 20 or the installation body 10. In order to avoid the above situation, in this embodiment, the recessed portion 2011 is an arc-shaped recessed portion, and the protruding portion 1111 is an arc-shaped protrusion, so that when the limiting protrusion 201 cooperates with the limiting groove 111, the friction between the protruding portion 1111 and the recessed portion 2011 is reduced, thereby avoiding damage to the battery 20 or the installation body 10 when the battery 20 is assembled with the installation body 10.

[0042] Furthermore, the battery 20 includes a first side wall 21 , a second side wall 22 and a third side wall 23 connected between the first side wall 21 and the second side wall 22 , and a plurality of limiting protrusions 201 are arranged on the first side wall 21 , the second side wall 22 and the third side wall 23 at intervals.

[0043] Specifically, the plurality of limiting protrusions 201 are arranged in a U-shape or an n-shape on the first side wall 21, the second side wall 22 and the third side wall 23, so that there are at least three connection points between the battery 20 and the first mounting plate 11. Figure 2 As shown, there are 9 limiting protrusions 201, of which 4 limiting protrusions 201 are arranged in pairs at opposite ends of the first side wall 21, one limiting protrusion 201 is arranged on the third side wall 23, and 4 limiting protrusions 201 are arranged in pairs at opposite ends of the second side wall 22. And there are 9 limiting grooves 111, which are arranged on the first mounting plate 11 relative to the 9 limiting protrusions 201, so that when the battery 20 is connected to the first mounting plate 11, there are 5 fixing points, thereby greatly improving the connection stability between the battery 20 and the first mounting plate 11.

[0044] Furthermore, a fixing portion 121 is disposed on the second mounting plate 12 , and the fixing portion 121 abuts against at least one of the battery 20 and the limiting protrusion 201 .

[0045] In this embodiment, a fixing portion 121 is provided on the second mounting plate 12, and the fixing portion 121 abuts against at least one of the battery 20 and the limiting protrusion 201 to apply a resisting force to the battery 20 or the limiting protrusion 201, thereby preventing the limiting protrusion 201 from escaping from the opening of the limiting groove 111 after the battery 20 is installed on the first mounting plate 11, thereby preventing the battery 20 from being separated from the first mounting plate 11.

[0046] In a specific embodiment, the fixing portion 121 includes a plurality of fixing posts 1211 , and the plurality of fixing posts 1211 are respectively pressed against a side of the plurality of limiting protrusions 201 away from the bottom surface of the limiting groove 111 .

[0047] Specifically, the resisting force applied by the protruding portion 1111 to the recessed portion 2011 is usually not too large. When the surfaces of the protruding portion 1111 or the recessed portion 2011 close to each other are worn or due to the difference in manufacturing, the resisting force applied by the protruding portion 1111 to the recessed portion 2011 is relatively low, which may cause the limiting groove 111 to fail to limit the limiting protrusion 201 or the limiting protrusion 201 to separate from the limiting groove 111 under the action of external force. Therefore, in this embodiment, the plurality of fixing columns 1211 are respectively pressed against the side of the groove bottom surface of the plurality of limiting protrusions 201 away from the limiting groove 111, so that the fixing columns 1211 apply a force on the limiting protrusion 201 that is the same as the depth direction of the limiting groove 111, so as to prevent the limiting protrusion 201 from separating from the limiting groove 111.

[0048] In a preferred embodiment, as shown in the attached Figure 1 and attached Figure 6 As shown, the fixing portion 121 includes a plurality of fixing columns 1211, a portion of which is against the side of the bottom surface of the plurality of limiting protrusions 201 away from the limiting groove 111, and the rest is against the side wall of the battery 20 away from the depth direction of the U-shape.

[0049] Specifically, based on the above-mentioned embodiments, part of the fixing columns 1211 in this embodiment rest against the side wall of the battery 20 that deviates from the first direction, thereby applying a resisting force to the side wall of the battery 20 that deviates from the first direction, thereby improving the connection stability between the battery 20 and the mounting body 10. At the same time, this arrangement can prevent the battery 20 from shaking on the first mounting plate 11, thereby causing wear between the protrusion 1111 and the recessed portion 2011.

[0050] In order to improve the structural strength of the fixing column 1211 and prevent the fixing column 1211 from being damaged when impacted by external force, in this embodiment, a reinforcing rib 30 is provided between the fixing column 1211 and the second mounting plate 12. Optionally, the fixing column 1211 may be a cylindrical column or a rectangular column.

[0051] In another preferred embodiment, as shown in the attached Figure 7 As shown, the fixing portion 121 includes a fixing plate 1212 , and the fixing plate 1212 abuts against a side wall of the battery 20 away from the first direction.

[0052] Specifically, since the depth direction of each limiting groove 111 is consistent with the first direction, after the limiting protrusion 201 is inserted into the limiting groove 111, it is only necessary to apply a resisting force consistent with the first direction to the side wall of the battery 20 away from the first direction, so that the limiting protrusion 201 can be resisted in the limiting groove 111, thereby preventing the limiting protrusion 201 from separating from the limiting groove 111 after the battery 20 is installed on the first mounting plate 11. In addition, compared with the multiple fixing columns 1211 on the second mounting plate 12, the fixing plate 1212 on the second mounting plate 12 has a higher structural strength and is not easily damaged.

[0053] Optionally, as attached Figure 8 To Attachment Fig.10 As shown, the limiting protrusion 201 may not be provided on the third side wall 23 of the battery 20, and the limiting protrusion 201 is only provided on the first side wall 21 and the second side wall 22 of the battery 20, so that the battery 20 can be fixed on the first mounting plate 11. At the same time, a fixing plate 1212 is provided on the second mounting plate 12. When the second mounting plate 12 is connected to the first mounting plate 11, the fixing plate 1212 abuts against the side wall opposite to the third side wall 23 of the battery 20 to apply a pushing force along the first direction to the battery 20, thereby pressing the limiting protrusion 201 tightly in the limiting groove 111 to prevent the battery 20 from detaching from the first mounting plate 11.

[0054] 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.

[0055] 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.

[0056] 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.
