Likewise, the following examples are only some examples and not all examples of the present application, and all other examples obtained by a person of ordinary skill in the art without any inventive work are within the scope of the present application.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

As used herein, an "electronic device" (or simply "terminal") includes, but is not limited to, an apparatus that is configured to receive/transmit communication signals via a wireline connection, such as via a Public Switched Telephone Network (PSTN), a Digital Subscriber Line (DSL), a digital cable, a direct cable connection, and/or another data connection/network, and/or via a wireless interface (e.g., for a cellular network, a Wireless Local Area Network (WLAN), a digital television network such as a DVB-H network, a satellite network, an AM-FM broadcast transmitter, and/or another communication terminal). A communication terminal arranged to communicate over a wireless interface may be referred to as a "wireless communication terminal", "wireless terminal" or "mobile terminal".

A cellular phone is an electronic device equipped with a cellular communication module.

It should be noted that, the middle frame of the electronic device is a frame structure adapted to the external shape of the electronic device, and generally, the middle frame, the front case and the rear cover together form a housing structure of the electronic device, and a battery of the electronic device is generally accommodated in a battery compartment disposed between the middle frame and the rear cover. The battery compartment is mainly used for fixing the battery and providing certain protection for the battery. The applicant found in his research that the thickness of the battery compartment itself is approximately 0.30-0.35 mm. In the scheme of thinning the whole machine, the bottleneck of thickness of the whole machine is generally positioned at the battery bin. The thickness of the whole machine at the battery compartment is generally composed of a shell, a display screen, the battery compartment, a battery body and other buffering bonding components.

Based on this, the applicant finds in further research that if the influence of the thickness of the battery bin can be eliminated, the thickness of the whole machine can be obviously reduced, and a relatively objective research direction is provided for a scheme for reducing the thickness of the whole machine.

Referring to fig. 1 and fig. 2 in combination, fig. 1 is a schematic structural diagram of a housing assembly of an electronic device in some embodiments of the present application, and fig. 2 is a schematic structural diagram of the housing assembly in the embodiment of fig. 1, which is disassembled; the electronic device in the application can comprise mobile terminal devices such as a mobile phone, a tablet computer, a notebook computer and a wearable device. The housing assembly 10 of the electronic device in the embodiment of the present invention generally includes a middle frame 110, a battery cover 120, and a fixing structure (not shown in the drawings, and will be described in detail below). The middle frame 110 and the battery cover 120 together enclose a space for accommodating the battery 50, and the fixing structure is used for fixing the battery 50 in the space.

Specifically, referring to fig. 3, fig. 3 is a schematic structural diagram of the middle frame 110 according to some embodiments of the present application, in which the middle frame 110 has a substantially rectangular structure or a rounded rectangular structure, and may include four sides (a first side L1, a second side S1, a third side L2, and a fourth side S2) connected end to end. Wherein the first side L1 and the third side L2 are longer sides disposed oppositely, and the second side S1 and the fourth side S2 are shorter sides disposed oppositely. In this or subsequent embodiments, the X direction is a direction substantially parallel to the shorter sides (S1, S2), and the Y direction is a direction substantially parallel to the longer sides (L1, L2).

It should be noted that all the directional indicators (such as upper, lower, left, right, front and rear … …) in the embodiment of the present application are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indicator is changed accordingly.

In some embodiments of the present application, the middle frame 110 is formed with a battery avoiding hole 111, and the battery 50 is disposed in the battery avoiding hole 111. Specifically, the middle frame 110 may directly surround to form a battery avoiding hole 111, that is, four edges (L1, S1, L2, S2) of the middle frame 110 connected end to end surround to form the battery avoiding hole 111. The battery 50 is disposed in the battery avoiding hole 111, that is, the battery avoiding hole 111 and the battery cover 120 cooperate to form a battery compartment for accommodating the battery 50. One end of the battery 50 is close to the battery cover 120, the other end of the battery 50 is close to the end of the battery avoiding hole 111 far away from the battery cover 120, and the other end of the battery 50 is not arranged to protrude out of the middle frame 110, so that the thickness of the traditional battery compartment is omitted, and the scheme of thinning the whole battery is realized.

Specifically, the battery 50 is generally used to power the internal components of the electronic device, and is typically connected to the electronic device via a circuit board. In the embodiment of the present application, the battery 50 is generally connected to and electrically connects internal components of the electronic device through a Flexible Printed Circuit (FPC) 60. Further, the FPC60 is generally disposed between the battery cover 120 and the middle frame 110 side by side with the battery 50, which can reduce the space occupied by the FPC 60. In addition, since the battery 50 is accommodated in the battery avoiding hole 111, an electrical test is generally required before the battery cover 120 is fastened, that is, the battery 50 is electrically connected to the electronic device motherboard through the FPC60 for electrical test. Based on the testing requirement, the FPC60 is generally designed to be lengthened and redundant, so that the battery 50 can pass through the battery avoiding hole 111 to be connected with the electronic device motherboard during testing, thereby improving the testing efficiency and convenience.

Further, in some embodiments of the present application, the middle frame 110 further includes a supporting plate 112, and the supporting plate 112 is fixedly connected to at least one of the four sides of the middle frame 110. For example, the supporting plate 112 may be fixedly connected to the first side L1, the second side S1, the third side L2 and the fourth side S2, respectively; the supporting plate 112 can also be fixedly connected with two or three of the four sides of the middle frame 110; of course, the supporting plate 112 may also be fixedly connected to four sides of the middle frame 110, which is not particularly limited in the embodiment of the present application.

Still further, the battery avoiding hole 111 may be formed in the supporting plate 112, that is, the battery avoiding hole 111 penetrates through the supporting plate 112, and the extending direction of the battery avoiding hole 111 is substantially perpendicular to the plane or XY plane where the supporting plate 112 is located. It can be understood that the battery avoiding hole 111 may be used to accommodate the battery 50, that is, the battery avoiding hole 111 and the battery cover 120 cooperate to form a battery compartment for accommodating the battery 50, so as to omit the thickness of the conventional battery compartment itself, thereby realizing a scheme of thinning the whole battery. Specifically, the shape of the battery relief hole 111 is adapted to the outer shape of the battery 50, so that at least a part of the battery 50 can be accommodated in the battery relief hole 111.

It should be noted that, in the application of the electronic device structure, a side of the middle frame away from the battery cover is generally provided with a display related structural member, so as to avoid that the battery 50 is pushed against the display when being assembled in the battery avoiding hole 111, thereby affecting the display effect of the display. In some embodiments of the present application, the battery 50 is not protruded from the end of the battery avoiding hole 111 far away from the battery cover 120, that is, the farthest distance of the battery 50 from the battery avoiding hole 111 is approximately equal to the end of the battery avoiding hole 111 far away from the battery cover 120. In other words, the end of the battery 50 away from the battery cover 120 is not protruded from the middle frame 110.

The casing subassembly for fixed battery that this application embodiment provided dodges the hole through seting up the battery at the center, and locates the battery and dodge downtheholely to make partly thickness of battery itself and the partial thickness coincidence of center, can save the thickness of battery compartment itself, and then for the complete machine attenuate provides the solution, further can also reduce the weight of complete machine and the processing cost of battery compartment.

The applicant has found that the effects that can be achieved with respect to different fastening structures are of particular importance, and based on this, the present application will be described with respect to different fastening structures.

Referring to fig. 4 and fig. 5, fig. 4 is a schematic exploded view of a housing 30 of an electronic device in another embodiment of the present disclosure, and fig. 5 is a schematic partial sectional view of the housing 30 in the embodiment of fig. 4 along a direction C-C in fig. 4, wherein in the embodiment of the present disclosure, a supporting portion 312 is taken as an example of a fixing structure, and the housing 30 is used for fixing a battery 50 of the electronic device.

Further, the housing 30 provided in the embodiment of the present application may generally include a middle frame 310, wherein the middle frame 310 is provided with a battery avoiding hole 311 and a supporting portion 312, and the battery 50 is disposed in the battery avoiding hole 311. The structure of the middle frame 310 in the embodiment of the present application is different from the structure of the middle frame 110 in the foregoing embodiment in that the middle frame 310 provided in the embodiment of the present application is provided with a support portion 312 for fixing the battery 50.

Specifically, referring to fig. 6, fig. 6 is an enlarged schematic view of a partial structure of the portion H in fig. 5, and the supporting portion 312 is formed to extend along an inner sidewall of the battery avoiding hole 311 toward an axial line direction of the battery avoiding hole 311, that is, the supporting portion 312 protrudes from the inner sidewall of the battery avoiding hole 311.

Further, the support portion 312 is disposed to protrude from an inner sidewall of the battery escape hole 311. The supporting portion 312 includes a first supporting surface 3121 and a second supporting surface 3122, the first supporting surface 3121 is formed by bending and extending toward the end of the battery avoiding hole 311 on the inner sidewall of the battery avoiding hole 311, and the second supporting surface 3122 is formed by extending toward the battery avoiding hole 311 on the edge of the first surface 3101, wherein the first supporting surface 3121 is used to fix the battery 50.

The adhesive for bonding the supporting portion 312 and the battery 50 may be double-sided adhesive, glue, or other adhesive with high viscosity, so as to facilitate stable bonding of the supporting portion 312 and the battery 50.

Further, the second support surface 3122 is flush with the first surface 3101 such that the end of the battery 50 near the first surface 3101 does not protrude beyond the battery relief hole 311.

In some embodiments of the present application, the supporting portion 312 further includes a supporting connecting surface 3123 connecting the first supporting surface 3121 and the second supporting surface 3122. Wherein the support connection surface 3123 is substantially parallel to an inner sidewall of the battery relief hole 311. It is understood that the second support surface 3122 is substantially perpendicular to the inner sidewall of the battery relief hole 311.

It should be noted that the terms "first", "second" and "third" in the present application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of indicated technical features.

Wherein the first side l1 and the third side l2 are longer sides oppositely arranged, and the second side s1 and the fourth side s2 are shorter sides oppositely arranged.

In the embodiments of the present application, the longer side of the battery 50 corresponds to the longer side of the middle frame 310, and the shorter side of the battery 50 corresponds to the shorter side of the middle frame 310.
