DETAILED DESCRIPTION

[0042] 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.

[0043] At present, the batteries in electronic devices are usually soft-pack batteries, for example, Figure 1 and Figure 2 As shown, the soft-pack battery includes a battery cell 122 and an aluminum-plastic film 103 coated on the outside of the battery cell 122. The soft-pack battery also includes a protection circuit board 124. The protection circuit board 124 is arranged on the outside of the aluminum-plastic film 103 and is electrically connected to the battery cell 122. An insulating layer 102 is coated on the outside of the protection circuit. The insulating layer 102 can be, for example, an insulating sealant tape to achieve insulation between the protection circuit board 124 and the electronic device 1 to avoid battery interference.

[0044] When a soft pack battery is assembled in an electronic device, it will occupy a large amount of internal space of the electronic device. Figure 1 and Figure 2 As shown, the electronic device 1 includes a middle frame 11, and the middle frame 11 includes a first surface and a second surface opposite to each other. The first surface of the middle frame 11 is used to install the screen module 17, and the second surface of the middle frame 11 is used to install the back cover 18. A groove penetrating the second surface is provided on the middle frame 11, and the soft-pack battery is provided in the groove, and the soft-pack battery is bonded to the bottom of the groove, for example, by a double-sided adhesive 101.

[0045] In the above-mentioned assembly method for the soft-pack battery, in order to ensure the stability of the connection between the soft-pack battery and the middle frame 11, it is necessary to ensure that there is sufficient contact area between the soft-pack battery and the middle frame 11 for bonding. However, an adhesive layer material for bonding is added between the soft-pack battery and the middle frame 11, which increases the occupation of the internal space of the electronic device, which is not conducive to the thinning design of the electronic device.

[0046] In order to solve the above technical problems, the present disclosure provides an electronic device, which uses a hard shell battery, a first mounting portion is provided on the middle frame, and a second mounting portion is provided on the hard shell of the hard shell battery, and the second mounting portion is connected with the first mounting portion to achieve the fixation of the hard shell battery. Such a design makes it easier to assemble the hard shell battery, reduces the contact area between the hard shell battery and the middle frame, and saves the adhesive layer material used to bond the battery, which not only saves costs, but also reduces the occupation of the internal space of the electronic device, which is conducive to the thinning design of the electronic device.

[0047] An exemplary embodiment of the present disclosure provides an electronic device. By way of example, the electronic device may be a mobile device such as a mobile phone, a tablet computer, a laptop computer, a PDA, a vehicle-mounted electronic device, a wearable device, an ultra-mobile personal computer (UMPC), a netbook, or a personal digital assistant (PDA). It may also be a non-mobile device such as a personal computer (PC), a television (TV), a teller machine, or a self-service machine.

[0048] like Figure 3 , Figure 4 and Figure 5 As shown, the electronic device 1 includes a middle frame 11 and a hard shell battery 12. A first mounting portion 115 is provided on the middle frame 11. The hard shell battery 12 includes a hard shell 121 and a battery cell 122 disposed in the hard shell 121. Exemplarily, the material of the hard shell 121 may be, for example, stainless steel, titanium alloy, super-strong aluminum or other new hard metal materials. Such a design can effectively improve the corrosion resistance, pressure resistance and sealing of the battery shell, thereby effectively preventing the leakage of electrolyte and gas, and further improving the reliability of the battery.

[0049] The hard shell 121 is provided with a second mounting portion 123, and the second mounting portion 123 is connected with the first mounting portion 115 to fix the hard shell battery 12. Exemplarily, the second mounting portion 123 and the first mounting portion 115 can be connected by screws or welding, etc., which is not specifically limited.

[0050] Such a design not only facilitates the assembly of the hard shell battery 12, but also reduces the contact area between the hard shell battery 12 and the middle frame 11, and saves the adhesive layer material used to bond the battery, which not only saves costs, but also reduces the occupancy of the internal space of the electronic device 1, which is conducive to the thinning design of the electronic device 1.

[0051] Combination Figure 7 and Figure 8 In one embodiment, the middle frame 11 includes a support plate 111 and a frame 112, and a first side plate 113 and a second side plate 114 are protrudingly provided on the back of the support plate 111.

Both ends of the first side plate 113 and both ends of the second side plate 114 are connected to the frame 112, and the first side plate 113, the second side plate 114 and the frame 112 are enclosed to form a receiving cavity, and the hard shell battery 12 is arranged in the receiving cavity, and the first mounting portion 115 is arranged on the first side plate 113 and the second side plate 114. For example, the first mounting portion 115 can be arranged on the surface of the first side plate 113 and the second side plate 114 facing the accommodating cavity, or can be arranged on the surface of the first side plate 113 and the second side plate 114 facing away from the accommodating cavity, and the setting position of the second mounting portion 123 is adapted to the setting position of the first mounting portion 115. With such a setting form, the space occupied by the electronic device 1 in the thickness direction is reduced, which is conducive to the thinning design of the electronic device 1.

[0052] Combination Figure 8 In one embodiment, a hollow structure 117 is provided in the area of ​​the support plate 111 corresponding to the accommodating cavity. In this way, on the one hand, the weight gain brought by the hollow structure 117 can make up for the weight increase brought by the hard shell battery 12, thereby facilitating the lightweight design of the electronic device 1. On the other hand, the space gain brought by the hollow structure 117 also helps to increase the capacity of the hard shell battery 12, thereby improving the user experience.

[0053] Combination Figure 8In one embodiment, the first mounting portion 115 is disposed on the surface of the first side plate 113 away from the accommodating cavity and the surface of the second side plate 114 away from the accommodating cavity. In this way, the space occupied by the first mounting portion 115 in the accommodating cavity is reduced, thereby effectively further increasing the capacity of the hard shell battery 12. Figure 7 and Fig. 9 , the second mounting portion 123 is arranged on the outer periphery of the hard shell 121. For example, the second mounting portion 123 is arranged on the two side surfaces of the hard shell 121 facing the first side plate 113 and the second side plate 114. The second mounting portion 123 is placed on the first side plate 113 and the second side plate 114, and is fixedly connected to the first mounting portion 115. Such a design can effectively improve the stability of the connection between the hard shell battery 12 and the middle frame 11 while facilitating the fixing of the hard shell battery 12, thereby improving the reliability of the electronic device 1.

[0054] Combination Figure 5 In one embodiment, the first mounting portion 115 and the second mounting portion 123 are fixedly connected by screws 13. In this way, it is convenient to connect the first mounting portion 115 and the second mounting portion 123, and it is also convenient to disassemble the hard shell battery 12, thereby improving the efficiency of disassembling and assembling the hard shell battery 12 and improving the safety when replacing the hard shell battery 12.

[0055] The electronic device 1 further includes a first insulating portion 14, which is disposed in a screw hole on the second mounting portion 123, and the screw 13 is passed through the first insulating portion 14. Exemplarily, a through hole is provided on the first insulating portion 14 for the screw 13 to pass through, and the screw 13 is connected to the first mounting portion 115 after passing through the through hole. With such a configuration, the screw 13 is insulated from the second mounting portion 123, and electromagnetic interference is avoided, thereby effectively improving the performance of the hard shell battery 12 and the electronic device 1.

[0056] Combination Figure 5In one embodiment, the screw 13 includes a head 131 and a screw rod 132 connected to each other. The first insulating portion 14 includes a first end 141, a second end 142, and a connecting portion 143 connected to the first end 141 and the second end 142 at both ends. The connecting portion 143 is arranged in the screw hole of the second mounting portion 123, and the screw rod 132 passes through the connecting portion 143 and is connected to the first mounting portion 115, so as to achieve the fixation between the first mounting portion 115 and the second mounting portion 123. The first end 141 of the first insulating portion 14 is located between the head 131 and the second mounting portion 123 to achieve the insulation between the screw 13 and the second mounting portion 123, and the second end 142 is located between the second mounting portion 123 and the first mounting portion 115 to achieve the insulation between the first mounting portion 115 and the second mounting portion 123. Such a design can further improve the insulation effect between the first mounting portion 115, the second mounting portion 123 and the screw 13, thereby further improving the performance of the hard shell battery 12 and the electronic device 1.

[0057] Combination Fig.14 , Fig.15 and Fig.16 In one embodiment, the second mounting portion 123 is welded to the first mounting portion 115.

For example, the shell 1212 is a rectangular structure, and the cover plate 1211 is also a rectangular structure. The cover plate 1211 can be fixedly connected to the shell 1212 by laser welding, for example, and each edge of the cover plate 1211 and the folded edge 1213 on the corresponding edge of the shell 1212 form a flange edge portion 1214. Such a design facilitates the connection between the cover plate 1211 and the shell 1212. After welding is completed, the flange edge 1214 on the outer periphery of the hard shell 121 can be processed into a desired shape by cutting, stamping, or other processes.

[0059] Combination Fig.11 , Fig.12and Fig.13 The hard shell battery 12 further includes a plurality of reinforcing sheets 125 disposed on the outer periphery of the hard shell 121.
