[0038] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0039] Portable electronic devices usually have built-in batteries. When users subsequently repair the electronic devices, it is difficult for the after-sales department to determine whether the users have privately disassembled the batteries. This makes it difficult or impossible to determine the responsibility for many after-sales issues, causing economic losses to electronic device manufacturers.

[0040] In order to solve the problems existing in the related art, the embodiments of the present disclosure provide a battery, a middle frame and an electronic device, wherein the battery and the middle frame are installed in the electronic device, a piezoelectric film layer is provided in at least one pulling portion of the battery, the piezoelectric film layer is electrically connected to the circuit board of the electronic device, and the piezoelectric film layer sends a first electrical signal to the circuit board to indicate that the piezoelectric film layer is physically squeezed; a detection component is provided in the middle frame, the detection component is located on the side of the battery compartment, the detection component is electrically connected to the circuit board of the electronic device, and the detection device sends a second electrical signal to the circuit board to indicate that the detection component detects physical squeezing, and in the subsequent maintenance process of the electronic device, the circuit board of the electronic device can determine whether the battery is subjected to external force impact or manual disassembly according to the first electrical signal or the second electrical signal, which is conducive to determining the cause of battery damage, so as to efficiently and accurately determine whether the user has privately disassembled the battery. In addition, after receiving the first electrical signal and the second electrical signal, the circuit board of the electronic device can also send a prompt message to remind that the battery may be at risk of damage, thereby avoiding safety problems.

[0041] According to an exemplary embodiment of the present disclosure, Figures 1 to 3 As shown, the embodiment of the present disclosure provides a battery 100, which is installed in an electronic device. The battery 100 can convert chemical energy into electrical energy through a reaction to power the electronic device so that the electronic device can work normally. The electronic device is such as a smart phone, a laptop computer, etc., and the battery 100 can be a lithium battery 100.

[0042] like Figures 1 to 3As shown, the battery 100 provided in the embodiment of the present disclosure includes a battery cell 10, which generally refers to an electrochemical battery cell 10 containing positive and negative electrodes, and the battery cell 10 is mainly composed of structures such as positive electrode materials, negative electrode materials, and electrolytes. The battery 100 also includes a battery protection board 11, in which a management chip, a metal oxide semiconductor field effect transistor (Metal Oxide Semiconductor Field Effect Transistor, referred to as MOSFET), a resistor, a capacitor, and a printed circuit board (Printed Circuit Board, referred to as PCB) are provided, and the battery protection board 11 and the battery cell 10 together constitute a finished battery 100.

[0043] refer to Figures 1 to 3 The battery 100 provided in the embodiment of the present disclosure further includes a lifting portion 20. By pulling the lifting portion 20 upward, the battery 100 can be quickly disassembled to improve the disassembly efficiency. There is at least one lifting portion 20, and the lifting portion 20 is usually arranged on the side of the battery 100. In the embodiment of the present disclosure, the battery 100 is provided with two lifting portions 20 as an example for description.

[0044] The lifting portion 20 covers the side of the battery cell 10, and the lifting portion 20 can be used as a fulcrum when taking the battery 100 out of the battery compartment 40. For example, for the battery 100 accommodated in the battery compartment 40, since the top surface of the battery 100 is flat and it is not convenient to apply external force, there is almost no gap between the side of the battery 100 and the side wall of the battery compartment 40, and it is not convenient to use as a fulcrum. Therefore, when it is necessary to take the battery 100 out of the battery compartment 40 (for example, to replace the battery 100), an external force can be applied to the lifting portion 20 to take the battery 100 out of the battery compartment 40 through the lifting portion 20.

[0045] Among them, reference Figures 1 to 3 , a piezoelectric film layer 21 is provided in at least part of the lifting portion 20, and the piezoelectric film layer 21 is electrically connected to the circuit board of the electronic device (not shown in the figure). For example, the piezoelectric film layer 21 can be electrically connected to the battery protection board 11 of the battery 100 through the connecting lead 211, and then electrically connected to the circuit board of the electronic device through the battery protection board 11. For another example, the piezoelectric film layer 21 can also be directly electrically connected to the circuit board of the electronic device through the connecting lead 211. The piezoelectric film layer 21 can send a first electrical signal to the circuit board to indicate that the piezoelectric film layer has been physically squeezed. After receiving the first electrical signal, the circuit board can store it, so that in the subsequent use of the electronic device or the repair of the electronic device, it can be judged whether the battery 100 has been physically squeezed according to whether the circuit board stores the first electrical signal.

[0046] Reference Figure 3 ,by Figure 3Based on the orientation shown in the figure, the lifting parts 20 are respectively provided on the left side and the right side of the battery 100. The piezoelectric film layer 21 can be provided only in the lifting part 20 on the left side, or only in the lifting part 20 on the right side, or the piezoelectric film layer 21 can be provided in the lifting parts 20 on both the left side and the right side at the same time.

[0047] In one example, when the user takes the battery 100 out of the battery compartment 40 via the lifting portion 20, the piezoelectric film layer 21 in the lifting portion 20 will be physically squeezed and send a first electrical signal. When the after-sales department of the electronic device repairs the electronic device, it can determine whether the user has privately disassembled the battery 100 based on whether the first electrical signal is recorded in the circuit board. If the first electrical signal is recorded in the circuit board, the after-sales department can determine that the user has privately disassembled the battery 100, and the damage to the battery 100 may be caused by the user, thereby improving the warranty determination efficiency and accuracy of the after-sales department and reducing the maintenance costs of electronic equipment manufacturers.

[0048] It should be noted that when the piezoelectric film layer 21 is provided on part of the structure of the lifting portion 20, the piezoelectric film layer 21 usually corresponds to the side of the battery cell 10, so that the piezoelectric film layer 21 can detect whether there is compression between the battery 100 and the side wall of the battery compartment 40. When the piezoelectric film layer 21 is provided on all the structures of the lifting portion 20, a part of the structure of the piezoelectric film layer 21 corresponds to the side wall of the battery cell 10, and a part of the structure of the piezoelectric film layer 21 does not correspond to the side wall of the battery cell 10. When the user pinches the lifting portion 20 with two fingers and lifts it, the structure of the piezoelectric film layer 21 that does not correspond to the side wall of the battery cell 10 will receive the pinching force of the user's fingers and send a first electrical signal.

[0049] In another example, it can be determined whether the internal structure of the electronic device is deformed and causes the battery 100 to be squeezed based on whether there is a first electrical signal in the circuit board, and then whether there is a safety risk in the current battery 100. For example, when the battery cell 10 of the battery 100 is swollen, the battery cell 10 will squeeze the piezoelectric film layer 21 to send out a first electrical signal. When the circuit board receives the first electrical signal, the circuit board can control the display panel to pop up a safety warning or control the electronic device to automatically shut down, so as to prevent the battery 100 from continuing to discharge and causing combustion, explosion, etc., and ensure user safety.

[0050] In the disclosed embodiment, a piezoelectric film layer is provided in at least one lifting portion of the battery. The piezoelectric film layer can send a first electrical signal to the circuit board of the electronic device to indicate that the piezoelectric film layer is physically squeezed. The first electrical signal can be stored in the electronic device, so that the after-sales department can determine whether the electronic device has been privately disassembled by the user based on whether the first electrical signal is stored in the electronic device, which is helpful for determining the cause of the battery damage.

[0051] In an exemplary embodiment, Figures 1 to 3 As shown, the battery 100 includes a battery cell 10 and a lifting portion 20, in which a piezoelectric film layer 21 is disposed. The piezoelectric film layer 21 is configured to send a first electrical signal outward when receiving physical compression.

[0052] like Figures 1 to 3 As shown, the pulling portion 20 includes a first insulating film layer 22 and a second insulating film layer 23, and the piezoelectric film layer 21 is located between the first insulating film layer 22 and the second insulating film layer 23, that is, the first insulating film layer 22, the piezoelectric film layer 21 and the second insulating film layer 23 are stacked in sequence, and the first insulating film layer 22 can be bonded and connected to the battery core 10 through a colloid. By providing the first insulating film layer 22 and the second insulating film layer 23 to cover the piezoelectric film layer 21, the structural strength of the pulling portion 20 can be enhanced, and the piezoelectric film layer 21 can be prevented from being electrically connected to an external device to affect the transmission of the first electrical signal.

[0053] Among them, the first insulating film layer 22 can be a resin film, such as PET (Polyethylene terephthalate, commonly known as polyester resin) film or PBT (polybutylene terephthalate, commonly known as polyester) film. The resin film has good tensile strength and can withstand large tensile force. During the disassembly of the battery 100 from the battery compartment 40, the disassembly equipment or the user can apply a large pulling force through the pulling part 20 to ensure the rapid disassembly of the battery 100 and improve the disassembly efficiency and disassembly reliability. The material of the second insulating film layer 23 can be a film layer made of polyimide (PI) material. The polyimide film has the property of being able to be bent at will and is used to cover the surface of the battery 100 to protect the battery 100.

[0054] Among them, reference Figures 1 to 3 The battery cell 10 of the battery 100 includes a Figure 1 The first side and the second side extending in the y direction (shown in FIG. 1 ), and the width direction (shown in FIG. 1 ) of the battery 100 Figure 1 The third side and the fourth side extend in the x direction (as shown in FIG. 1 ), the third side and the fourth side are located between the first side and the second side, and the fourth side is provided with a battery protection plate 11.

[0055] In one example, reference Figures 1 to 3, the first side of the battery 100 is provided with a first lifting portion 20a, the second side is provided with a second lifting portion 20b, and at least one of the first lifting portion 20a and the second lifting portion 20b is provided with a piezoelectric film layer 21. It can be determined that when the user removes the battery 100 through the first lifting portion 20a, the piezoelectric film layer 21 in the first lifting portion 20a can receive the pinching force of the user's fingers or disassembly tools, and when the user removes the battery 100 through the second lifting portion 20b, the first side of the battery 100 will be pushed against the side wall of the battery compartment 40, and the piezoelectric film layer 21 in the first lifting portion 20a is squeezed by the side wall of the battery compartment 40.

[0056] In another example (this example is not shown in the drawings), a first lifting portion is provided on the first side, a second lifting portion is provided on the second side, a third lifting portion is provided on the third side, and a piezoelectric film layer is provided on at least one of the first lifting portion, the second lifting portion and the third lifting portion.

[0057] It is understandable that when the piezoelectric film layer 21 is provided in a plurality of lifting portions 20, when the user removes the battery 100 from the lifting portion 20 on any side of the battery 100 as a force application point, the piezoelectric film layer 21 can detect physical squeezing and generate an electrical signal. By increasing the number of piezoelectric film layers 21, multiple disassembly methods of the user can be detected, which is conducive to improving the accuracy of judging whether the battery 100 is privately disassembled by the user.

[0058] According to an exemplary embodiment of the present disclosure, Figure 1 As shown, combined with Figures 4 to 6 , an embodiment of the present disclosure provides a middle frame 200, and the middle frame 200 is applied to an electronic device.

[0059] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the middle frame 200 includes a middle frame body 30, which is usually used as a bracket of the electronic device. Other structures and devices can be installed and fixed on the middle frame body 30. For example, the display screen, rear shell, circuit board, small board, battery 100 and other devices of the electronic device can be installed on the middle frame body 30. The material of the middle frame body 30 can be a high-strength, low-weight alloy material such as aluminum alloy, stainless steel, titanium alloy, etc., to improve the impact resistance of the electronic device. The material of the middle frame body 30 can also be a plastic structure.

[0060] refer to Figure 1 , Figure 4 , Figure 5 and Figure 6The middle frame 200 further includes a battery compartment 40, which is disposed on the middle frame body 30. The battery compartment 40 can be used to accommodate the battery 100 provided in any of the aforementioned embodiments of the present disclosure. The battery compartment 40 in the embodiment of the present disclosure can also accommodate the battery 100 in the related art. The shape of the battery compartment 40 is the same as that of the battery 100. For example, if the present disclosure provides a rectangular battery 100, the battery compartment 40 is also rectangular.

[0061] refer to Figure 1 , Figure 4 , Figure 5 and Figure 6 The middle frame 200 further includes a detection assembly 50, which is disposed on the middle frame body 30 and is electrically connected to a circuit board (not shown) of the electronic device. The detection assembly 50 may be located at a side of the battery compartment 40, so that a portion of the structure of the detection assembly 50 may constitute a portion of the side wall of the battery compartment 40.

[0062] The detection component 50 can send a second electrical signal to the circuit board to indicate that the detection component 50 detects physical squeezing. In one example, when a user extends a disassembly tool into the space between the battery 100 and the side wall of the battery compartment 40 to pry the battery 100 out of the battery compartment 40 using the disassembly tool, if the user uses the detection component 50 as a fulcrum for the disassembly tool, the disassembly tool will squeeze the detection component 50, causing the detection component 50 to send a second electrical signal to the circuit board of the electronic device, and the circuit board of the electronic device can receive and store the second electrical signal, and then the after-sales department can determine whether the user has privately disassembled the battery 100 based on the second electrical signal.

[0063] In the embodiment of the present disclosure, a detection component is provided in the middle frame. When the detection component is physically squeezed, it can send a second electrical signal to the circuit board of the electronic device. The second electrical signal can be transmitted to the electronic device and stored in the electronic device. The after-sales department can determine whether the electronic device has been privately disassembled by the user based on whether the second electrical signal is stored in the electronic device, which is helpful for determining the cause of battery damage.

[0064] In an exemplary embodiment, Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the middle frame 200 includes a middle frame body 30, a battery compartment 40 and a detection component 50. The battery compartment 40 is disposed in the middle frame body 30, the detection component 50 is disposed in the middle frame body 30, and the detection component 50 is located on the side wall of the battery compartment 40. When the detection component 50 detects physical squeezing, it can send a second electrical signal to the outside.

[0065] like Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, the middle frame body 30 is provided with a mounting groove 31 , and the mounting groove 31 is used to install and fix the detection component 50 .

[0066] refer to Figure 1 , Figure 4 , Figure 5 and Figure 6 The detection assembly 50 includes a piezoelectric sensor 51 and a cover plate 52. The piezoelectric sensor 51 is located between the side wall of the mounting groove 31 and the cover plate 52. The cover plate 52 is provided with a first contact 521. When the cover plate 52 is physically squeezed, the first contact 521 of the cover plate 52 can contact the piezoelectric sensor 51, so that the piezoelectric sensor 51 generates a second electrical signal. Figure 1 , Figure 4 , Figure 5 and Figure 6 The mounting groove 31 includes a first side wall 311 and a second side wall 312 opposite to each other. The second side wall 312 is closer to the battery compartment 40 than the first side wall 311. The piezoelectric sensor 51 is disposed on the first side wall 311. It can be determined that when the cover plate 52 moves toward the first side wall 311, the first contact 521 on the cover plate 52 can contact the piezoelectric sensor 51 on the first side wall 311.

[0067] In one example, the piezoelectric sensor 51 is fixedly connected to the mounting slot 31. The cover plate 52 is movably connected to the mounting slot 31, and the cover plate 52 is made of a material with low extensibility. When the cover plate 52 is physically squeezed, the cover plate 52 can move relative to the mounting slot 31, so that the first contact 521 on the cover plate 52 can contact the piezoelectric sensor 51, so that the piezoelectric sensor 51 generates a second electrical signal. Materials with low extensibility include iron, polycarbonate (PC), etc.

[0068] In another example, the piezoelectric sensor 51 is fixedly connected to the mounting groove 31. The cover plate 52 is fixedly connected to the mounting groove 31, and the cover plate 52 is made of a material capable of elastic deformation. When the cover plate 52 is physically squeezed, the cover plate 52 can produce elastic deformation, and the first contact 521 on the cover plate 52 contacts the piezoelectric sensor 51, so that the piezoelectric sensor 51 generates a second electrical signal. The material capable of elastic deformation is rubber, silicone, etc.

[0069] In another example, the piezoelectric sensor 51 is fixedly connected to the first contact 521 on the cover plate 52. The cover plate 52 is movably connected to the mounting groove 31, and the cover plate 52 is made of a material with low extensibility. When the cover plate 52 is physically squeezed, the cover plate 52 can move relative to the mounting groove 31, so that the side of the piezoelectric sensor 51 away from the first contact 521 and the first side wall 311 of the mounting groove 31 are squeezed, so that the piezoelectric sensor 51 generates a second electrical signal.

[0070] In another example, the piezoelectric sensor 51 is fixedly connected to the first contact 521 on the cover plate 52. The cover plate 52 is fixedly connected to the mounting groove 31, and the cover plate 52 is made of a material capable of elastic deformation. When the cover plate 52 is physically squeezed, the cover plate 52 can generate elastic deformation, and the side of the piezoelectric sensor 51 away from the first contact 521 is squeezed with the first side wall 311 of the mounting groove 31, so that the piezoelectric sensor 51 generates a second electrical signal.

[0071] refer to Figures 5 to 7 , the cover plate 52 can be connected to the mounting groove 31 by means of snap-fitting. For example, the second side wall 312 of the mounting groove 31 is provided with a snap-fitting groove 32, which is formed by the surface of the second side wall 312 being recessed toward a side away from the first side wall 311, and the cover plate 52 is provided with a snap-fitting buckle 523, which protrudes from the cover plate 52 and extends toward the direction of the snap-fitting groove 32. In the assembled state, the snap-fitting buckle 523 extends into the snap-fitting groove 32 so that the cover plate 52 and the mounting groove 31 are snap-fitted.

[0072] In some embodiments, Figure 6 As shown, when the cover plate 52 is installed in the installation slot 31, the first contact 521 of the cover plate 52 and the piezoelectric sensor 51 are in a separated state, a reserved gap 60 is generated between the cover plate 52 and the first side wall 311, and the piezoelectric sensor 51 does not generate a second electrical signal. When the user uses a disassembly tool to try to lift the battery 100, the disassembly tool will use the cover plate 52 as a fulcrum, that is, the disassembly tool will physically squeeze the cover plate 52, so that the cover plate 52 is relative to the middle frame body 30 ( Figure 6 When the first side wall 311 moves in the opposite direction of the x direction shown in FIG, the cover plate 52 will cover the reserved gap 60, and the first contact 521 on the cover plate 52 will contact and squeeze the piezoelectric sensor 51, so that the piezoelectric sensor 51 generates a second electrical signal.

[0073] Among them, reference Figure 5 and Figure 6 The detection assembly further includes a reset member 53, which is used to provide a reset function for the cover plate 52 in the detection assembly 50. Figure 6, the reset member 53 is arranged on the first side wall 311, and the cover plate 52 is provided with a second contact 522, and the second contact 522 is arranged corresponding to the reset member 53. When the external force disappears, the elastic restoring force of the reset member 53 will push the cover plate 52 to reset, so as to prevent the cover plate 52 from continuously squeezing the detection component 50 to continue the second electrical signal, and to prevent the electronic device from continuously storing the second electrical signal to generate power consumption, thereby extending the battery life of the electronic device. In the disclosed embodiment, by setting the reset member 53, during the process of the user privately disassembling the battery 100, each time the user stops applying force until the force is reapplied, a second electrical signal will be generated, so that the after-sales department can learn the number of private disassemblies by the user through the second electrical signal, which is helpful for judging the cause of damage to the battery 100. The reset member 53 can be, for example, a spring pin, a silicone pad, etc.

[0074] According to an exemplary embodiment of the present disclosure, Figures 1 to 6 As shown, an embodiment of the present disclosure provides an electronic device, such as a smart phone, a laptop computer, a smart wearable device, etc., which is equipped with an independent power supply.
