[0054] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, 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 invention.

[0055] The core of the present invention is to provide a battery installation structure that can fix the battery without using battery adhesive. Another core of the present invention is to provide an electronic device including the above battery installation structure that can fix the battery without using battery adhesive.

[0056] Please refer to Figures 1 - 4The embodiment of the utility model provides a battery installation structure for installing a metal shell battery 1 in a battery compartment 2. The metal shell battery 1 includes an upper cover 12 and a lower cover 13. The side of at least one of the upper cover 12 and the lower cover 13 is provided with a protruding flange edge; the battery installation structure includes a sheet member 11 and a limiting member. The sheet member 11 protrudes from the side of the flange edge, and the sheet member 11 is used to cooperate with the side of the battery compartment 2 for limiting; the limiting member is used to limit at least one end of the metal shell battery 1.

[0057] When installing the metal shell battery 1, slide the sheet member 11 along the side of the battery compartment 2 until the metal shell battery 1 slides into place. At this time, the sheet member 11 is limited by the side of the battery compartment 2 to prevent the metal shell battery 1 from shaking to the side in the battery compartment 2 and causing lateral position deviation; then, use the limiter to limit at least one end of the metal shell battery 1 to prevent the metal shell battery 1 from sliding in the direction of the front and rear ends, thereby preventing the front and rear position deviation along the metal shell battery 1. It can be seen that the battery installation structure can realize the side limit and front and rear direction limit of the metal shell battery 1.

[0058] In addition, in the prior art, the battery is fixed in the battery compartment of the electronic device by adhesives such as easy-to-pull adhesives or double-sided adhesives. However, with the release of the new EU battery regulations and the requirements of eco-design, the elimination of battery adhesives is an industry development trend. Therefore, how to avoid the use of battery adhesives to achieve battery fixation is also a problem that needs to be solved by those skilled in the art.

[0059] In order to solve this technical problem, in some embodiments, the battery installation structure further includes a slide rail 21, which is used to be arranged on the side of the battery compartment 2, and the sheet 11 is slidably matched with the slide rail 21, and the slide rail 21 is used to limit the movement of the sheet 11 along the direction of the battery installation surface away from the battery compartment 2. When installing the metal shell battery 1, the sheet 11 is inserted into the slide rail 21 and the sheet 11 is slid along the slide rail 21 until the sheet 11 slides into place, which indicates that the steel shell battery 1 is installed in place. At this time, the slide rail 21 has a limiting effect on the sheet 11 along the direction of the battery installation surface away from the battery compartment 2, which can prevent the steel shell battery 1 from leaving the battery compartment 2 along the direction of the battery installation surface away from the battery compartment 2; at the same time, combined with the limiting member mentioned above, the limiting member is used to limit at least one end of the steel shell battery 1 to prevent the steel shell battery 1 from sliding back and forth along the length direction of the slide rail 21, so that the steel shell battery 1 can be fixed.

[0060] It can be seen that the battery installation structure uses a mechanical structure to fix the metal shell battery 1, avoiding the use of battery adhesive to fix the metal shell battery 1, and complies with EU regulations and eco-design requirements. In addition, by making the limiter detachable, the metal shell battery 1 can be detachably installed by sliding the sheet member 11 relative to the slide rail 21; and the metal shell battery 1 is snapped in by sliding cooperation between the sheet member 11 and the slide rail 21. Compared with other detachable structures, this structure is simple, occupies less space, and is easy to disassemble. In addition, compared with the prior art that uses battery adhesive to stick the battery as a whole into the battery compartment 2, the battery installation structure uses the cooperation of the sheet member 11 and the slide rail 21 to achieve the snap-in fixation of the metal shell battery 1 and the battery compartment 2. During the whole machine drop test, the possibility of the metal shell battery 1 body being hit by the battery compartment 2 is greatly reduced, thereby improving the reliability of the fixation of the metal shell battery 1.

[0061] Further, in order to facilitate the sheet member 11 to slide into the slide rail 21, please refer to Figure 5 , Figure 6 and Figure 7 In some embodiments, the battery installation structure further includes a clearance groove 22, which is arranged on the side of the battery compartment 2 and communicated with the entrance end of the slide rail 21, so that the sheet member 11 is placed in the clearance groove 22 and then slides into the slide rail 21 from the entrance end. That is to say, when installing the metal shell battery 1, the sheet member 11 is first aligned with the clearance groove 22, and the metal shell battery 1 is placed in the battery compartment 2. The clearance groove 22 has a avoiding effect on the sheet member 11, so that the sheet member 11 falls into the clearance groove 22. Since the entrance end of the slide rail 21 is communicated with the clearance groove 22, after the sheet member 11 is placed in the clearance groove 22, an external force can be applied to the metal shell battery 1 to make the sheet member 11 slide relative to the slide rail 21.

[0062] Furthermore, considering the simplicity of the structure, in some embodiments, the slide rail 21 is a slide groove. That is, in this embodiment, the slide rail 21 is formed by directly slotting the side wall of the battery compartment 2, which has a simple structure and is easy to set up. When the side of the battery compartment 2 is provided with the above-mentioned clearance groove 22, the slide groove is connected to the clearance groove 22, so that the sheet 11 falls into the clearance groove 22 and is just aligned with the entrance end of the slide groove.

[0063] In addition, the above embodiment does not limit the specific setting position of the slide groove, as long as the slide groove can be connected with the clearance groove 22, can be slidably matched with the sheet member 11, and has a limiting effect on the sheet member 11 in the direction away from the battery installation surface of the battery compartment 2.

[0064] In some embodiments, the relief groove 22 penetrates through the side wall of the battery compartment 2 along the height direction of the side wall of the battery compartment 2. The sliding groove extends a preset height distance in a direction away from the battery mounting surface of the battery compartment 2 and extends a preset length distance in a direction away from the relief groove 22 from the connection between the sliding groove and the relief groove 22. That is to say, one side of the sliding groove is directly connected to the battery compartment 2, and the battery mounting surface of the battery compartment 2 serves as one side wall of the sliding groove. This solution facilitates the setting of the corresponding sheet-like member 11. In this case, the relief groove 22 penetrates through the side wall from the top end of the side wall of the battery compartment 2 to the end where it is connected to the battery mounting surface, so that the relief groove 22 is connected to the sliding groove.

[0065] It should be noted that in the embodiments of the present invention, the specific ranges of the length L and the height h of the sliding rail 21 are not limited, and those skilled in the art can set them according to actual needs. For example Figure 9 and Figure 10 As shown, in order to facilitate a direct view of the sliding rail 21 and the relief groove 22, the sliding rail 21 and the relief groove 22 are represented by cross-hatching.

[0066] In addition, considering the convenience of implementing the limiting member, please refer to Figure 3 and Figure 4 In some embodiments, the limiting member includes a limiting step 23. The limiting step 23 is provided at the end of the sliding rail 21 and is used to limit the sliding stroke of the sheet-like member 11. That is to say, when the sheet-like member 11 slides along the sliding rail 21, when the sheet-like member 11 slides to the limiting step 23, it abuts against the limiting step 23. Under the blocking action of the limiting step 23, the sheet-like member 11 cannot continue to slide, realizing the limitation of the sliding stroke of the sheet-like member 11, indicating that the sheet-like member 11 slides in place. When the sliding rail 21 is a sliding groove, the sliding groove is a blind groove with a closed end. At this time, the end of the closed end serves as the limiting step 23 to limit the sliding stroke of the sheet-like member 11.

[0067] In addition, in some embodiments, the limiting member includes a fixing device 3. The fixing device 3 is used to be provided at the tail of the battery compartment 2 to limit one end of the metal shell battery 1 close to the entrance end of the sliding rail 21. It should be noted that one end of the metal shell battery 1 close to the entrance end of the sliding rail 21 refers to the end that is closer to the entrance end of the sliding rail 21 relative to the end of the sliding rail 21. This end can be defined as the tail end of the metal shell battery 1, corresponding to the tail of the battery compartment 2. That is to say, when the metal shell battery 1 slides in place, a fixing device 3 is provided at the tail of the battery compartment 2, and the fixing device 3 stops and limits the tail end of the metal shell battery 1, realizing the fixation of the tail end of the metal shell battery 1.

[0068] It should be noted that the fixing device 3 can be provided at the tail of the battery compartment 2 in a detachable manner. For example, it is locked to the tail of the battery compartment 2 by screws.

[0069] In addition, please refer to Figure 11 and Figure 12 , in some embodiments, the fixing device 3 is a functional structural member for implementing a preset function of the electronic device. That is to say, in this embodiment, the original functional structural member of the electronic device with a preset function is used to limit the tail end of the metal housing battery 1. That is, the function of limiting the tail end of the metal housing battery 1 is integrated on this functional structural member of the electronic device, so that this functional structural member not only has the original preset function, but also has the function of limiting the tail end of the metal housing battery 1, thereby saving structural members and making the structure compact.

[0070] It should be noted that the above-mentioned various embodiments do not limit the specific setting manner of the sheet-like member 11, as long as it can protrude from the side of the metal housing battery 1.

[0071] Please refer to Figure 13 , Figure 14 and Figure 15 , in some embodiments, the flange edge includes a first flange edge protruding from the side of the upper cover 12 and a second flange edge protruding from the side of the lower cover 13; the sheet-like member 11 includes a first sheet-like member 111 and a second sheet-like member 112, the first sheet-like member 111 protrudes from the first flange edge; the second sheet-like member 112 protrudes from the second flange edge; the first sheet-like member 111 and the second sheet-like member 112 overlap. That is to say, the sheet-like member 11 is formed on the flange edge of the metal housing battery 1. When the first flange edge of the upper cover 12 of the metal housing battery 1 is formed, the first sheet-like member 111 is simultaneously formed on the first flange edge. When the second flange edge of the lower cover 13 of the metal housing battery 1 is formed, the second sheet-like member 112 is simultaneously formed on the second flange edge. When the upper cover 12 and the lower cover 13 of the metal housing battery 1 are assembled, the first sheet-like member 111 and the second sheet-like member 112 overlap. It can be seen that the sheet-like member 11 in this form is convenient to process.

[0072] Furthermore, in some embodiments, the thickness of the first sheet-like member 111 is the same as the thickness of the first flange edge, and the thickness of the second sheet-like member 112 is the same as the thickness of the second flange edge. That is to say, the thickness of the first sheet-like member 111 is determined by the thickness of the first flange edge, and the thickness of the second sheet-like member 112 is determined by the thickness of the second flange edge. In this way, during processing, a steel plate with a uniform thickness can be used to integrally process the first flange edge and the first sheet-like member 111, and a steel plate with a uniform thickness can be used to integrally process the second flange edge and the second sheet-like member 112, further improving the convenience of processing.

[0073] In addition, it can be understood that, in order to improve the stability of the fixation of the metal housing battery 1, in some embodiments, the sheet-like members 11 protrude from both sides of the metal housing battery 1. Correspondingly, the slide rails 21 are distributed on both sides of the battery compartment 2, so as to realize the snap connection between the metal housing battery 1 and the battery compartment 2 through the sliding fit of the sheet-like members 11 on both sides of the metal housing battery 1 with the corresponding slide rails 21, and this structure makes the fixation of the metal housing battery 1 more stable.

[0074] In some embodiments, at least two spaced-apart sheet-like members 11 are provided on one side of the metal housing battery 1, and at least one sheet-like member 11 is provided on the other side of the metal housing battery 1; when the number of the sheet-like members 11 on both sides of the metal housing battery 1 is the same, the sheet-like members 11 on both sides of the metal housing battery 1 are symmetrically arranged. That is to say, the sheet-like members 11 in this embodiment are discrete structural members, which are equivalent to forming at least three sliding clamping points on both sides of the metal housing battery 1 to realize the stable fixation of the metal housing battery 1. In addition, by the sliding fit of multiple discrete sheet-like members 11 with the corresponding slide rails 21, compared with the sliding fit of a single sheet-like member 11 with a relatively long length with the slide rails 21, the contact area between the whole sheet-like member 11 and the slide rails 21 can be reduced, and the friction force can be reduced. In addition, when the number of the sheet-like members 11 on both sides of the metal housing battery 1 is the same, the sheet-like members 11 on both sides of the metal housing battery 1 are symmetrically arranged, which can make the stress points on both sides of the metal housing battery 1 more uniform, so that the fixation of the metal housing battery 1 is more reliable.

[0075] In addition to the above battery installation structure, the present utility model also provides an electronic device including the battery installation structure disclosed in the above embodiments. The electronic device further includes a housing, and the housing is provided with a battery compartment 2. The sheet-like members 11 of the battery installation structure are in cooperation and limit with the side part of the battery compartment 2. For the structures of other parts of the electronic device, reference may be made to the related art, which will not be elaborated herein.

[0076] Since the electronic device includes the above battery installation structure, therefore, it has the same beneficial effects as the above battery installation structure, which will not be elaborated herein.

[0077] It should also be noted that in this specification, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0078] The various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments, and the same or similar parts among the various embodiments may be referred to each other.

[0079] The above has introduced in detail the battery installation structure and the electronic device provided by the present utility model. Specific examples are used in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model.
