[0054] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0055] Combine Figure 1 and Figure 2As shown, this embodiment provides an electronic device, which includes: a middle frame module 1, a mainboard module 2, a battery module 3 and a protection module 4.

[0056] The middle frame module 1 is provided with a mainboard compartment 11 and a battery compartment 12 , which are separated from each other by a rib structure 13 ; the mainboard module 2 is located in the mainboard compartment 11 , and the battery cell module 3 is located in the battery compartment 12 .

[0057] An avoidance gap 131 is provided on the rib structure 13 , and the protection module 4 is located in the avoidance gap 131 . The protection module 4 is electrically connected to the mainboard module 2 and the battery module 3 , respectively.

[0058] In the electronic device of this embodiment, the mainboard module 2 and the battery module 3 are respectively arranged in the mainboard compartment 11 and the battery compartment 12 of the middle frame module 1. The rib structure 13 between the mainboard compartment 11 and the battery compartment 12 uses an avoidance gap 131 to accommodate the protection module 4. The protection module 4 can be connected to the mainboard module 2 and the battery module 3 cells respectively, playing the role of power transmission and battery cell protection.

[0059] In this embodiment, the protection module 4 and the battery module 3 are arranged independently and can be independently produced and assembled and disassembled. The protection module 4 will not be affected by the aging of materials such as the electrolyte in the battery module 3 and can be independently recycled and reused, so that the electronic device has better environmental performance.

[0060] The motherboard module 2, also known as the mainboard, is the core component of any electronic device. It's also called the main control board or main chip board. The motherboard integrates key electronic components like the processor, memory, storage chips, wireless communication chips, and power management chips. It controls the various functions and operations of the phone. For example, the processor handles data operations, the storage chips store data, and the wireless communication chips transmit phone signals.

[0061] Combine Figure 3 As shown, in some embodiments, a first abutment contact 41 is provided on a side of the protection module 4 facing the mainboard module 2 , and a second abutment contact 42 is provided on a side of the protection module 4 facing the battery module 3 .

[0062] The mainboard module 2 is provided with a mainboard contact 21 on the side facing the protection module 4 , and the mainboard contact 21 is in contact with the first abutting contact 41 ; the battery cell module 3 is provided with a battery cell contact 31 on the side facing the protection module 4 , and the battery cell contact 31 is in contact with the second abutting contact 42 .

[0063] Through the above arrangement, the protection module 4 can be contacted and connected with the mainboard module 2 and the battery cell module 3 respectively through the first abutment contact 41 and the second abutment contact 42. When the protection module 4, the mainboard module 2 and the battery cell module 3 are respectively assembled into the middle frame module 1, the first abutment contact 41 of the protection module 4 is exactly abutted with the position of the mainboard contact 21 of the mainboard module 2, and the second abutment contact 42 of the protection module 4 is exactly abutted with the position of the battery cell contact 31 of the battery cell module 3, so that the battery cell module 3 and the mainboard module 2 establish an electrical connection.

[0064] In some possible implementations, reference Figure 4 As shown, the first abutting contact 41 includes a first P+ contact, a first P-contact 412, and at least one first control contact 413, and the mainboard contact 21 includes a second P+ contact, a second P-contact 212, and at least one second control contact 213. The first P+ contact and the second P+ contact are in corresponding abutment contact, the first P-contact 412 and the second P-contact 212 are in corresponding abutment contact, and the at least one control contact and the at least one second control contact 213 are in one-to-one abutment contact.

[0065] The second abutting contact 42 includes a first B+ contact and a second B- contact 312, and the cell contact 31 includes a second B+ contact and a second B- contact 312. The first B+ contact and the second B+ contact are in corresponding abutting contact, and the second B- contact 312 and the second B- contact 312 are in corresponding abutting contact.

[0066] In some embodiments, the protection module 4 is provided with at least one first clamping structure, and at least one of the mainboard module 2 and the battery cell module 3 is provided with a second clamping structure, and the first clamping structure and the second clamping structure are clamped and connected.

[0067] Through the above arrangement, the protection module 4 can be connected to the mainboard module 2 or the battery cell module 3 by using the first clamping structure and the second clamping structure, ensuring the reliability of the contact connection between the first abutment contact 41 and the mainboard contact 21, and the second abutment contact 42 and the battery cell contact 31.

[0068] Combine Figure 2 As shown, in some embodiments, a narrowing rib 1311 is provided at the bottom of the avoidance gap 131 . The narrowing rib 1311 extends in a direction parallel to the rib structure 13 and connects the rib structures 13 on both sides of the avoidance gap 131 .

[0069] In this embodiment, to compensate for the strength loss caused by the provision of the relief notch 131 in the rib structure 13, a narrowing rib 1311 is arranged within the relief notch 131, parallel to the rib structure 13 and connected to the rib structure 13 on both sides. The narrowing rib 1311 compensates for the strength of the rib structure 13, ensuring the structural strength of the middle frame module 1. Furthermore, the narrow width of the narrowing rib 1311 does not affect the assembly of the protection module 4 within the relief notch 131.

[0070] Combine Figure 5 As shown, in some embodiments, the protection module 4 is provided with a groove structure 43 , which has the same shape as the narrowing rib 1311 , and the groove structure 43 is snap-connected to the narrowing rib 1311 .

[0071] Through the above arrangement, the protection module 4 can utilize the groove structure 43 to engage with the narrowing rib 1311 , thereby improving the reliability and stability of the protection module 4 in the avoidance gap 131 .

[0072] Combine Figure 5 and Figure 6 As shown, in some embodiments, the protection module 4 includes a first circuit board 44 , a chip device 45 and a resistor and capacitor device 46 .

[0073] First circuit board 44 is arranged along the thickness of middle frame module 1, with two working surfaces (e.g., first working surface 4401 and second working surface 4402) facing mainboard module 2 and battery cell module 3, respectively. Chip components 45 are embedded within first circuit board 44, and resistor and capacitor components 46 are located on one of the working surfaces.

[0074] In this embodiment, considering that the rib structure 13 has a larger dimension along the thickness direction, but a smaller dimension along the direction between the main board module 2 and the battery cell module 3, and the first circuit board 44 in the protection module 4 needs to carry chip devices 45 and resistor and capacitor devices 46, the dimension parallel to the working surface is difficult to be compressed, but the dimension perpendicular to the working surface can be further compressed by embedding the chip device 45.

[0075] Therefore, through the above arrangement, the first circuit board 44 of the protection module 4 is arranged along the thickness direction of the middle frame module 1, with one working surface facing the mainboard module 2 and the other protection module 4 facing the battery cell module 3, and the chip device 45 is embedded in the design, and the resistor and capacitor devices 46 are arranged on the working surface. The structure of the protection module 4 conforms to the spatial shape of the avoidance gap 131 and can make full use of the space within the avoidance gap 131.

[0076] Exemplarily, the first circuit board 44 is a printed circuit board (PCB).

[0077] Combine Figure 5 As shown, in some embodiments, the protection module 4 further includes a packaging layer 47 . The packaging layer 47 is located on the two working surfaces, and the resistor and capacitor components 46 located on the working surfaces are all immersed in the corresponding packaging layer 47 .

[0078] When the protection module 4 includes the first abutting contact 41 and the second abutting contact 42 , the first abutting contact 41 and the second abutting contact 42 are respectively located on the packaging layer 47 corresponding to the two working surfaces.

[0079] Through the above arrangement, both working surfaces of the first circuit board 44 are covered by the packaging layer 47 , which can protect the wiring structure and the resistor and capacitor components 46 on the working surfaces.

[0080] Combine Figure 5 As shown, in some embodiments, the protection module 4 also includes a second circuit board 48, which is vertically connected to the working surface where the resistor and capacitor components 46 are located and is located on one side edge of the working surface. The second circuit board 48 is used for circuit bridging between the first circuit board 44 and the corresponding first abutment contact 41 or the second abutment contact 42.

[0081] In this embodiment, since a certain number of resistors and capacitors 46 are necessarily present in protection module 4, these resistors and capacitors 46 can only be arranged on the working surface of first circuit board 44. To address the placement of first abutting contacts 41 or second abutting contacts 42, the thickness of encapsulation layer 47 is increased so that encapsulation layer 47 covers all resistors and capacitors 46, thereby allowing first abutting contacts 41 and second abutting contacts 42 to be arranged on the surface of encapsulation layer 47. However, this structure places first abutting contacts 41 and second abutting contacts 42 at a large distance from the working surface of first circuit board 44, lacking a reliable electrical connection. Therefore, a second circuit board 48 is arranged perpendicularly to one side edge of the working surface. One end of second circuit board 48 is connected to the working surface, and the other end extends to the surface of encapsulation layer 47. This second circuit board 48 can be used as a circuit bridge between first circuit board 44 and first abutting contacts 41 or second abutting contacts 42.

[0082] In addition, for another working surface of the first circuit board 44 where the resistor and capacitor components 46 are not provided, the thickness of the packaging layer 47 is relatively small, and the corresponding first abutting contact 41 or second abutting contact 42 can be directly connected to the circuit of the working surface.

[0083] Exemplarily, the second circuit board 48 is a printed circuit board (PCB).

[0084] Combine Figure 3 、 Figure 5 and Figure 6As shown, in some embodiments, the working surface includes a first working surface 4401 and a second working surface 4402 , and the encapsulation layer 47 includes a first encapsulation layer 4701 and a second encapsulation layer 4702 .

[0085] The first working surface 4401 faces the mainboard module 2, and the second working surface 4402 faces the battery cell module 3; the resistor and capacitor component 46 and the first packaging layer 4701 are respectively located on the first working surface 4401, and the resistor and capacitor component 46 are completely immersed in the first packaging layer 4701, and the first abutment contact 41 is located on the first packaging layer 4701; the second packaging layer 4702 is located on the second working surface 4402, and the second abutment contact 42 is located on the second packaging layer 4702.

[0086] Through the above arrangement, the first working surface 4401 of the first circuit board 44 faces the main board module 2, and the resistor and capacitor components 46 are arranged thereon. After being sealed by the packaging layer 47, the first abutting contact 41 is arranged on the surface of the packaging layer 47. The part of the resistor and capacitor component 46 on the first working surface 4401 can be cut and connected to the main board module 2 with the help of the first abutting contact 41 for battery connection.

[0087] Combine Figure 5 As shown, in some embodiments, when the protection module 4 includes a groove structure 43, the groove structure 43 is located on the side surface of the first circuit board 44 facing the bottom of the avoidance gap 131; since the first circuit board 44 is arranged along the thickness direction of the middle frame module 1, when the groove structure 43 is arranged on the first circuit board 44, it is only formed by using the side surface of the first circuit board 44 to form a depression, which has no effect on the two working surfaces of the first circuit board 44, and has little effect on the chip devices 45, resistor and capacitor devices 46 and wiring structures on the first circuit board 44, and is easy to process and has low cost.

[0088] Combine Figure 5 As shown, in some embodiments, when the protection module 4 includes the second circuit board 48 , the second circuit board 48 is located on the edge of the first working surface 4401 facing the bottom of the avoidance gap 131 .

[0089] Through the above arrangement, the second circuit board 48 is arranged on the edge of the bottom of the first working surface 4401 facing the avoidance gap 131, which can realize the circuit bridging of the first abutting contact 41 and the first circuit board 44, and the position of the second circuit board 48 corresponds to the position of the groove structure 43 of the first circuit board 44, which can compensate for the strength loss of the bottom of the first circuit board 44 due to the opening of the groove structure 43.

[0090] Combine Figure 7As shown, in some embodiments, the protection module 4 includes a charging circuit 401, a discharging circuit 402, and a protection module 403. The charging circuit 401 is electrically connected to the mainboard module 2 and the battery module 3, respectively, and the discharging circuit 402 is electrically connected to the mainboard module 2 and the battery module 3, respectively. The protection module 403 is electrically connected to the charging circuit 401 and the discharging circuit 402, respectively. The protection module 403 is used to monitor the operating status of the charging circuit 401 and / or the discharging circuit 402, and control the charging circuit 401 and / or the discharging circuit 402 to be shut down in an abnormal state.

[0091] Through the above arrangement, the protection module 4 can monitor the working status of the battery module 3 and control charging or discharging to stop in an abnormal state, thereby protecting the battery module 3 and the mainboard module 2.

[0092] In some embodiments, the electronic device can be any of various types of computer system devices that are mobile or portable and perform wireless communication. Specifically, the electronic device can be a mobile phone or smart phone (e.g., an iPhone™-based phone, an Android™-based phone), a portable gaming device (e.g., a Nintendo DS™, a PlayStation Portable™, a Gameboy Advance™, an iPhone™), a laptop computer, a PDA, a portable internet device, a music player, a data storage device, other handheld devices, and devices such as headphones.

[0094] In some cases, the electronic device can perform multiple functions (e.g., play music, display video, store pictures, and receive and send phone calls). If desired, the electronic device can be a cellular phone, a media player, other handheld device, a wristwatch device, a pendant device, an earpiece device, or other compact portable device.
