[0023] See attached Figure 1 To Attachment Figure 3 , the electronic device of the embodiment of the present application includes a first shell 1 and a second shell 2 that are detachably connected, and a mainboard 3 is arranged between the first shell 1 and the second shell 2. The first shell 1 and the second shell 2 form the appearance of the electronic device and can be made of metal or plastic material. In addition, the electronic device can have a roughly rectangular parallelepiped shape, but is not limited to this. The material, size and shape of the first shell 1 or the second shell 2 can be formed in a variety of ways. The first shell 1 and the second shell 2 also include a battery module arranged next to the mainboard 3, and the battery module includes a battery frame 4 and a battery 8 arranged in the battery frame 4. The battery 8 is electrically connected to the mainboard 3. The first shell 1 and the second shell 2 can be detachably separated, and when the first shell 1 and the second shell 2 are separated, the battery module leaks out. In the figure, the battery module is illustrated as being arranged close to the mainboard, but the embodiment is not limited to this.

[0024] A preferred embodiment of the present invention includes a first elastic module 9 connected to the battery module. The first elastic module 9 is configured to push the battery module after the second shell 2 is disassembled so that the electrical connection between the battery module and the main board 3 is disconnected. In some embodiments, the battery module is arranged near the second shell 2, and when the second shell 2 is disassembled, the electrical connection between the battery module and the main board 3 is disconnected, and when the second shell 2 is installed, the electrical connection between the battery module and the main board 3 is reconnected. In some embodiments, it can be arranged that when the battery module is correctly installed and the second shell 2 is also correctly installed, the electrical connection between the battery module and the main board 3 is completed. In an embodiment of the present application, the first elastic module 9 may include 4 groups of springs.

[0025] In order to achieve further electrical disconnection, the electronic device further includes a first fixing unit, a second fixing unit and a release unit, wherein the first fixing unit is configured to fix the battery module when the second housing 2 is not installed; the second fixing unit is configured to fix the battery module after the second housing 2 is installed, and the release unit is configured to release the first fixing unit from fixing the battery module when the second housing 2 is installed. When the battery 8 is installed, the first fixing unit fixes the battery module; after the second housing 2 is installed, the first fixing unit releases the fixation of the battery module through the release unit, and the battery module is fixed by the second fixing unit.

[0026] The battery frame 4 can be set in a basically rectangular shape and can be configured to have a certain thickness. The thickness of the battery frame 4 can be greater than the thickness of the battery 8, which plays a role in preventing the battery 8 from being hit. The battery frame 4 and the battery can be connected in a variety of ways, such as the battery frame 4 is fixedly wrapped around each side of the battery 8. In an optimized embodiment of the present application, the battery frame 4 is slidably connected to the battery 8, that is, the battery 8 is inserted into the battery frame 4 by sliding. Of course, it can also be set that the battery frame 4 includes a first frame for loading the battery 8 and a second frame 14 that is slidably arranged with the first frame. After the battery 8 is installed in the first frame, the first frame is pushed to slide into the second frame 14 to finally complete the installation of the battery 8. The first frame can be set to wrap each side of the battery 8.

[0027] The second fixing unit is configured to be between the battery frame 4 and the second shell 2. The second fixing unit includes a rear rib 5, a plurality of rear seat ribs 6 arranged on the rear rib 5, and the plurality of rear seat ribs 6 are respectively connected to the battery frame 4 or the battery. When the second shell 2 is installed and pressed, the second shell 2 presses the rear seat ribs 6, and the rear seat ribs 6 press the battery frame 4 or the battery 8. The rear rib 5 is used to connect the plurality of rear seat ribs 6 to facilitate the installation of the product. In an embodiment having a first frame and a second frame 14 that is slidably arranged with the first frame, it can be arranged that when the second shell 2 is installed and pressed, the second shell 2 presses the rear seat ribs 6, and the rear seat ribs 6 press the first frame.

[0028] The release unit includes a rear pressure rib 7 disposed on the second housing 2 and a connecting block 11 for driving the first fixing unit to move. The rear pressure rib 7 is fixedly connected to the second fixing unit. Preferably, the rear pressure rib 7 can be integrally formed with the second fixing unit. The rear pressure rib 7 can also be disposed on both sides of the rear rib 5.

[0029] See attached Figure 3 A first elastic module 9 is disposed on the side of the battery frame 4. In some preferred embodiments, the battery frame 4 can be disposed in the same plane as the main board 3 and parallel to each other. A battery signal connection unit 10 extends from the battery frame 4 to achieve electrical connection with the main board 3.

[0030] The first elastic module 9 and the battery signal connection unit 10 can be arranged on the same side, and can be arranged on the side close to the main board 3. The battery 8 is electrically connected to the main board 3 through the battery signal connection unit 10. The first elastic module 9 abuts between the battery 8 and the battery frame 4. In an embodiment in which the battery frame 4 includes a first frame and a second frame 14, the battery 8 can be configured to abut inside the first frame, and the first frame and the second frame 14 are slidably connected to each other. When the first frame slides to abut against the first elastic module 9, it compresses the first elastic module 9, and the rebound force of the first elastic module 9 forms an outward thrust on the battery 8. In other embodiments, the first elastic module 9 is arranged between the main board 3 and the battery module, and when the second shell 2 is removed, the first elastic module 9 pushes the battery module outward so that the electrical connection between the battery module and the main board 3 is disconnected.

[0031] Of course, in other embodiments, the first elastic module 9 can be arranged at other positions, for example, the first elastic module 9 can be arranged below the battery 8. When the second housing 2 is removed, the second housing 2 releases the limit of the battery 8, and the first elastic module 9 pushes the battery 8 to move upward so that the battery module is electrically disconnected from the mainboard 3. In other words, the first elastic module 9 is configured to provide a thrust to the battery module to disconnect the battery module from the mainboard 3 after the battery module is installed.

[0032] When the battery 8 is installed, the first elastic module 9 is compressed; when the second shell 2 is folded, the second shell 2 releases the limit of the battery 8, and the first elastic module 9 pushes the battery 8 to move outward, and the battery 8 is electrically disconnected from the mainboard 3. In some embodiments, the battery signal connection unit 10 is fixedly connected to the battery 8. In this case, the battery signal connection unit 10 can move outward together with the battery 8, and the battery signal connection unit 10 is separated from the mainboard 3 to achieve the disconnection of the electrical connection between the battery 8 and the mainboard 3. Of course, in other embodiments, the battery signal connection unit 10 and the battery 8 can be configured to be separable from each other. When the battery 8 moves outward, the electrical connection between the battery 8 and the battery signal connection unit 10 is disconnected, and the electrical connection between the battery 8 and the mainboard 3 is disconnected. In other words, the first elastic module 9 pushes the battery module to disconnect the electrical connection between the battery module and the mainboard 3.

[0033] The release unit includes a rear pressure rib 7 provided on the second housing 2 and a connection block 11 connected to the rear pressure rib 7 and used to drive the first fixing unit to move. The rear pressure rib 7 can be provided on both sides of the battery frame 4, and the connection block 11 is provided directly below the rear pressure rib 7 in the vertical direction. When the second housing 2 is installed, the rear pressure rib 7 presses the connection block 11 downward, and the rise and fall of the connection block 11 drives the first fixing unit to move so that the first fixing unit releases the fixation of the battery module.

[0034] The following is combined with Figure 4 To Attachment Fig. 9 Describe in detail the structure and working principle of the connection block.

[0035] See attached Figure 4 To Attachment Fig. 9 The first fixing unit includes a first hook 15 disposed on the main board 3 or the first housing 1 and a second hook 16 disposed on the battery module. The first hook 15 and the second hook 16 cooperate with each other to fix the battery module when the battery module is installed. The first hook 15 is configured to move with the release unit. The first hook 15 is configured to be movable in a vertical direction (also referred to as a Z direction) and a left-right direction (also referred to as an X direction) relative to the release unit.

[0036] In order to realize the movement of the first hook 15 in the vertical direction, the connecting block 11 is configured to include a second base 13 and a first base 12 stacked on the second base 13, and a third elastic module 18 is arranged between the first base 12 and the second base 13, and the first base 12 and the second base 13 can move relative to each other in the vertical direction (also referred to as the Z direction) through the third elastic module 18. The second base 13 can be arranged to be fixed on the main board 3 or on the first shell 1. In the embodiment in which the second base 13 is fixed on the first shell 1, the second base 13 can be arranged to be integrally formed with the first shell 1. The first base 12 is provided with a first hook 15, and the battery 8 is provided with a second hook 16. The first hook 15 and the second hook 16 cooperate with each other to fix the battery 8 when the battery 8 is installed. It can be understood that in the embodiment in which the battery 8 is arranged on the battery frame 4, the second hook 16 is arranged on the battery frame 4, and the first hook 15 and the second hook 16 cooperate with each other to fix the battery 8 when the battery 8 is installed. In other embodiments, the second base 13 may be disposed on the first housing 1 by bonding, welding, or the like.

[0037] In order to realize the movement of the first hook 15 in the left and right direction (also called the X direction), the first fixing unit is arranged on the first base 12, and a second elastic module 17 for driving the first fixing unit to move left and right relative to the first base 12 is arranged between the first fixing unit and the first base 12. Specifically, the first hook 15 includes a body arranged in the first base 12 and a hook body extending out of the body. The first base 12 is provided with a slot 20 and a slide rail 21 for cooperating with the first hook 15; the slot 20 is used to prevent the first hook 15 from being separated from the first base 12; the slide rail 21 enables the first hook 15 to slide left and right (also called the X direction) along the first base 12. A second elastic module 17 is arranged between the body of the first hook 15 and the first base 12; when the second shell 2 is not installed, the first hook 15 and the second hook 16 cooperate to fix the battery 8; when the second shell 2 is installed, the battery 8 is fixed by the second fixing unit, and at this time, the first hook 15 is driven by the second elastic module 17 to restore the initial position to release the fixation of the battery 8. In the embodiment of the present application, the second elastic module 17 may include two groups of springs. A third hook 19 is provided on the second base 13. When the first hook 15 is pressed downward, the first hook 15 and the second hook 16 cooperate to fix the battery 8; when the first hook 15 is not pressed downward, the first hook 15 rises and is blocked by the third hook 19, and the third hook 19 blocks the first hook 15 in the Z direction.

[0038] The following is combined with Fig.10 To Attachment Fig.24 Describe in detail the working principle of this application.

[0039] When installing the battery 8, first press the first hook 15 downward to assemble the push-in battery 8. When the battery 8 slides to abut against the first elastic module 9, the first elastic module 9 is compressed. The spring contained in the first elastic module 9 is in a compressed state. The rebound force of the first elastic module 9 forms an outward thrust on the battery 8. At this time, the second hook 16 moves to the top of the first hook 15.

[0040] Then, the first hook 15 is pushed toward the battery 8, and the first hook 15 compresses the second elastic module 17. When the first hook 15 moves to the gap between the second hook 16 and the battery 8, the first hook 15 is released. At this time, the pressure pressing the first hook 15 disappears, and the first hook 15 has no pressure in the vertical direction. The third elastic module 18 can push the first base 12 and the first hook 15 to move upward to a position where the first hook 15 is substantially flush with the second hook 16. The first hook 15 hooks the second hook 16, and the first hook 15 and the second hook 16 are in a locked state, thereby fixing the battery 8 in the Y direction. At this time, the spring contained in the second elastic module 17 is in a compressed state, and the spring contained in the third elastic module 18 is in an uncompressed state. In an embodiment of the present application, the third elastic module 18 may include 4 groups of springs.

[0041] When assembling the second housing 2, the spring contained in the first elastic module 9 is in a compressed state, the rear seat rib 6 enters the outside of the push-in battery 8 (the side away from the first elastic module 9), fixes the push-in battery 8 in the Y direction, and at the same time, the rear pressure rib 7 presses the first base 12, the first hook 15 and compresses the third elastic module 18. The pressure of the rear pressure rib 7 causes the first hook 15 and the second hook 16 to stagger in the Z direction, and lose the obstruction of the second hook 16. Under the action of the rebound force of the second elastic module 17, the first hook 15 moves to the left (away from the direction of the battery 8) to the bottom of the second hook 16. Due to the limited position in the Z direction, the first hook 15 will not rebound to the initial position, and the first hook 15 and the second hook 16 are no longer locked. At this time, the rear seat rib 6 is the only thing that fixes the push-in battery 8 in the Y direction. The first hook 15 can no longer fix the battery 8.

[0042] When removing the second shell 2, the rear seat ribs 6 and the rear pressure ribs 7 are removed together after the second shell 2 is removed. The rear seat ribs 6 no longer fix the push-in battery 8. After the push-in battery 8 loses its fixation in the Y direction, the battery 8 moves outward under the action of the rebound force of the spring contained in the first elastic module 9. When the battery 8 moves outward, the electrical connection between the battery 8 and the main board 3 is disconnected, so that the electrical connection between the battery 8 and the main board 3 is disconnected simultaneously when the second shell 2 is disassembled. At this time, the spring contained in the first elastic module 9 returns to the natural state, the spring contained in the second elastic module 17 is in an uncompressed state, and the spring contained in the third elastic module 18 is in a compressed state.

[0043] Reference Fig.25 To Attachment Fig. 27 In order to realize the positional relationship of each component, the following limitations can be made.

[0044] 1) a: The distance between the rear of the first hook 15 and the inner side of the first base 12 in the X direction is the rebound distance of the spring contained in the second elastic module; 2) b: the distance between the buckle portion of the first hook 15 and the outer side of the first base 12 in the X direction; 3) c: the distance between the first base 12 and the second base 13 in the Z direction, which is the vertical compression distance of the spring contained in the third elastic module; 4) d: minimum vertical displacement of the first hook 15; 5) e: thickness of the first hook 15; 6) f: the distance between the third hook and the second base 13 in the vertical direction.

[0045] Preferably, you need to ensure: a>b, f>e: ensure the left and right displacement distance of the first hook 15; c>d: ensure the up and down displacement distance of the first hook 15.
