Detailed Description

The present application will be described in further detail with reference to the following drawings and examples. It is to be noted that the following examples are only illustrative of the present application, and do not limit the scope of the present application. 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". Examples of mobile terminals include, but are not limited to, satellite or cellular telephones; a Personal Communications System (PCS) terminal that may combine a cellular radiotelephone with data processing, facsimile and data communications capabilities; PDAs that may include radiotelephones, pagers, internet/intranet access, Web browsers, notepads, calendars, and/or Global Positioning System (GPS) receivers; and conventional laptop and/or palmtop receivers or other electronic devices that include a radiotelephone transceiver. 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 opened with a battery avoiding hole 111, and the battery avoiding hole 111 is used for accommodating the battery 50. 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 is far from the battery cover 120, and the end of the battery 50 far from the battery cover 120 does not 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 flexible circuit board 60 is generally disposed between the battery cover 120 and the middle frame 110 side by side with the battery 50, so that the space occupied by the flexible circuit board 60 can be reduced; of course, the flexible circuit board 60 may also be stacked with the battery 50 and disposed between the battery cover 120 and the middle frame 110, which is not particularly limited in the embodiment of the present application. 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 flexible circuit board 60. Based on the testing requirement, the flexible circuit board 60 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 equipment motherboard in a conduction manner 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 opened on 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 of the supporting plate 112 or the XY plane as shown in fig. 3. 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 at 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 50 far away from the battery cover 120 and 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 does not protrude 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 in combination, fig. 4 is a schematic exploded view of a housing assembly 10 of an electronic device in some embodiments of the present disclosure, and fig. 5 is a schematic partial sectional view of the housing assembly 10 of fig. 4 along a direction a-a in fig. 4.

Specifically, the connecting member 130 is generally disposed between the middle frame 110 and the battery cover 120, and the battery cover 120 is disposed on the middle frame 110, so as to fix the battery 50 and protect the battery 50. Further, the connection member 130 is disposed opposite to the battery relief hole 111, and the connection member 130 is used for fixing the battery 50.

Further, a side of the battery 50 close to the connection member 130 is fixedly connected to the connection member 130, for example, the battery 50 and the connection member 130 may be fixedly connected by means of adhesive. The battery 50 and the connecting member 130 are fixedly connected by a glue, that is, a first glue 101 is disposed between the battery 50 and the connecting member 130 for fixedly bonding the battery 50 and the connecting member 130. The first adhesive 101 may be a double-sided adhesive tape, glue, or other adhesive with a relatively strong viscosity, so as to facilitate relatively stable bonding between the battery 50 and the connecting member 130. In the assembling process, the first colloid 101 is generally disposed on the connecting member 130, and then the battery 50 is bonded to the first colloid 101, so that the battery 50 is bonded to the connecting member 130.

It can be understood that the connecting member 130 can be made of elastic material with certain elasticity, such as foam, rubber, plastic, etc., and the surface thereof is generally soft, so as not to scratch the battery 50 during use, and at the same time, can play a role in buffering and preventing the top print phenomenon.

In some embodiments of the present disclosure, the connecting member 130 may be fixedly connected to the battery cover 120, or the connecting member 130 may also be fixedly connected to the middle frame 110, and different connection manners of the connecting member 130 will be described below.

Referring to fig. 5 again, in fig. 5, the connecting member 130 is fixedly connected to the battery cover 120. Specifically, the side of the connection member 130 close to the cell cover 120 is adhesively connected to the cell cover 120, and the side of the connection member 130 remote from the cell cover 120 is adhesively connected to the battery 50. Further, the connecting member 130 is fixedly connected to the battery cover 120 through a glue, that is, a second glue 102 is disposed between the connecting member 130 and the battery cover 120 for fixedly bonding the connecting member 130 and the battery cover 120. The second adhesive 102 may be a double-sided adhesive, glue, or other adhesive with a strong adhesive property, so as to facilitate the stable bonding of the connecting member 130 and the battery cover 120. In the assembling process, the second adhesive body 102 is generally disposed on the connecting member 130, and then the connecting member 130 with the second adhesive body 102 is adhered to the battery cover 120, so as to achieve the adhesion and fixation of the connecting member 130 and the battery cover 120.

In the above embodiment of the present application, the connecting member 130 is firstly bonded to the cell cover 120, then the battery 50 is bonded to the connecting member 130 so that the battery 50 and the cell cover 120 form an assembly, and then the cell cover 120 and the middle frame 110 are assembled so that the battery 50 is disposed in the battery avoiding hole 111. Based on the connection manner of the connection member 130, it is generally preferable that the connection member 130 in the embodiment of the present application completely covers the end portion of the battery 50 near the battery cover 120, that is, the projection area of the connection member 130 on the middle frame 110 is preferably not smaller than the opening area of the battery avoiding hole 111 in the embodiment of the present application. For example, the projected area of the connection member 130 on the middle frame 110 is equal to the open area of the battery escape hole 111, so that the connection member 130 just can completely cover the end of the battery escape hole 111. Of course, in other embodiments, the projected area of the connecting member 130 on the middle frame 110 may be slightly larger or smaller than the opening area of the battery avoiding hole 111, as long as the stability of the bonding of the battery 50 can be ensured.

In other embodiments of the present application, please refer to fig. 6, fig. 6 is a schematic cross-sectional view of a portion of the housing assembly 10 according to other embodiments of the present application, and the connecting member 130 in fig. 6 is fixedly connected to the middle frame 110.

Specifically, the connecting member 130 may generally include a connecting body 131 and a bending portion 132 connected to the connecting body 131 in a bending manner. The bending part 132 is formed by bending and extending along a direction of the end of the connecting body 131 away from the battery cover 120, that is, the bending part 132 is disposed on a side of the connecting body 131 away from the battery cover 120. In addition, the connecting body 131 and the bending portion 132 may be formed by integral molding, or may be separately formed and assembled together.

Further, a side of the connection body 131 away from the battery cover 120 is adhesively connected to the battery 50, so as to fix the battery 50 in the battery avoiding hole 111. The side of the bending part 132 away from the battery cover 120 is adhesively connected to the middle frame 110, so that the connecting member 130 can be stably connected to the middle frame 110.

Specifically, the connecting body 131 and the battery 50 are fixedly connected by glue, that is, as described above, the first glue 101 is disposed between the connecting body 131 and the battery 50 for fixedly bonding the battery 50 and the connecting body 131. The bent portion 132 is used for being fixedly connected with the middle frame 110 to fix the connecting member 130, so as to achieve stable installation of the battery 50.

Further, the bending portion 132 may be adhered to the inner sidewall of the middle frame 110 for fixing, or adhered to the supporting plate 112 of the middle frame 110 for fixing. In the embodiment of the present application, the bending portion 132 and the supporting plate 112 are exemplarily connected by adhesive bonding. Specifically, a third adhesive 103 is disposed between the bending portion 132 and the supporting plate 112 of the middle frame 110 for adhering and connecting the bending portion 132 and the supporting plate 112. The third adhesive 103 may be a double-sided adhesive, glue, or other adhesive with a strong viscosity, so as to facilitate the firm bonding between the bending portion 132 and the supporting plate 112. It can be understood that, the bending portion 132 is adhered to one side of the supporting plate 112 close to the battery cover 120, in the assembling process, the third glue body 103 is generally disposed on the end portion of the bending portion 132 close to the supporting plate 112, and then the bending portion 132 with the third glue body 103 is adhered to one side of the supporting plate 112 close to the battery cover 120, so as to achieve the adhesion and fixation of the bending portion 132 and the supporting plate 112, and further achieve the fixed connection of the connecting member 130 and the middle frame 110.

Of course, in this embodiment of the present application, the assembly process is slightly different from that of the previous embodiment. Specifically, in this embodiment, the battery 50 is firstly adhered to the connecting body 131 of the connecting member 130, the bent portion 132 of the connecting member 130 is adhered to the middle frame 110, and then the battery cover 120 and the middle frame 110 are assembled to dispose the battery 50 in the battery avoiding hole 111. It can be understood that, based on the arrangement of the bending portion 132, the projected area of the connecting member 130 on the middle frame 110 is inevitably larger than the opening area of the battery avoiding hole 111, so that the battery 50 can be stably arranged in the battery avoiding hole 111.

Specifically, the area of the projection of the connecting body 131 of the connecting member 130 on the middle frame 110 is not smaller than the area of the opening of the battery avoiding hole 111, and the projection of the bent portion 132 of the connecting member 130 on the middle frame 110 is at least partially disposed along the outer periphery of the battery avoiding hole 111. In other words, the projection of the connecting body 131 of the connecting member 130 on the middle frame 110 completely covers the battery avoiding hole 111, and the area of the projection of the connecting member 130 on the middle frame 110 is larger than the opening area of the battery avoiding hole 111.

The electronic equipment's that this application embodiment provided casing subassembly dodges the hole through seting up the battery on the center to in dodging the hole with the battery, further set up the connecting piece in order to be used for fixed battery between center and battery cover, avoid the battery to produce relative displacement in the use, can reduce electronic equipment complete machine thickness and promote the stability of complete machine simultaneously.

Based on this, an embodiment of the present application further provides an assembling method of an electronic device, please refer to fig. 7, where fig. 7 is a flowchart illustrating the assembling method of the electronic device in some embodiments of the present application, and the assembling method substantially includes the following steps:

s701, providing a middle frame, and forming a battery avoidance hole in the middle frame;

s702, providing a connecting piece, bonding and connecting a battery on one side of the connecting piece close to the middle frame, and arranging the battery in a battery avoiding hole;

and S703, providing a battery cover, and covering the battery cover on one side of the middle frame, which is close to the connecting piece.

It is understood that the structure and specific flow of the housing assembly 10 of the electronic device related to the assembling method of the embodiment of the present application may refer to the foregoing embodiments, and detailed description is omitted in the embodiment of the present application.

Referring to fig. 8 and 9 in combination, fig. 8 is a schematic exploded view of a housing assembly 20 of an electronic device in another embodiment of the present disclosure, and fig. 9 is a schematic partial sectional view of the housing assembly 20 in the embodiment of fig. 8 along a direction B-B in fig. 8.

The housing assembly 20 provided by the embodiment of the present application may generally include a middle frame 210 and a supporting member 230. The middle frame 210 has a battery avoiding hole 211, the battery 50 is disposed in the battery avoiding hole 211, and the structure of the middle frame 210 is substantially the same as that of the middle frame 110 in the previous embodiment, so that the present application is not described in detail.

Specifically, the middle frame 210 and the supporting member 230 cooperate to define a space for accommodating the battery 50, and the supporting member 230 is further used for fixing the battery 50 in the space. In other words, the supporting member 230 and the battery relief hole 211 of the middle frame 210 together enclose a space for accommodating the battery 50, and the battery 50 is accommodated in the battery relief hole 211.

It can be understood that the housing assembly 20 provided in the embodiment of the present application may further include a battery cover 220, where the battery cover 220 is disposed on a side of the battery 50 away from the supporting member 230 and is fixedly connected to the middle frame 210. Further, the battery cover 220, the supporting member 230 and the battery avoiding hole 211 of the middle frame 210 together enclose a space for accommodating the battery 50, the end of the battery 50 close to the supporting member 230 is fixedly connected with the supporting member 230, and a certain gap is kept between the end of the battery 50 far from the supporting member 230 and the battery cover 220, so that the battery cover 220 protects the battery 50.

In some embodiments of the present application, the middle frame 210 further includes a first surface 2101 and a second surface 2102 disposed opposite to each other, and the battery relief hole 211 extends through the first surface 2101 and the second surface 2102. Here, the supporting member 230 is disposed close to the first surface 2101, that is, the supporting member 230 is disposed at one side of the first surface 2101 and opposite to the battery relief hole 211.

Specifically, the support 230 is disposed opposite to the battery relief hole 211, and the support 230 is used to fix the battery 50. Further, the projected area of the supporting member 230 on the middle frame 210 is larger than the opening area of the battery avoiding hole 211, so that the supporting member 230 can be firmly bonded. One side of the supporting member 230 close to the middle frame 210 is simultaneously bonded to the middle frame 210 and the battery 50, so that the supporting member 230 and the middle frame 210 can have a relatively stable connection relationship while fixing the battery 50.

For example, the supporting member 230 may be adhered to the middle frame 210 by a glue, and the supporting member 230 may be adhered to the battery 50 by a glue. Based on this, in the embodiment of the present application, the end of the battery 50 close to the supporting member 230 is disposed substantially flush with the supporting member 230, so that the supporting member 230 can simultaneously bond the middle frame 210 and the battery 50 through the fourth colloid 204. It is understood that the fourth glue 204 may be a double-sided adhesive, a glue, or the like with a strong adhesive property, so as to facilitate a more stable bonding of the supporting member 230, the middle frame 210, and the battery 50.

In some embodiments of the present application, please refer to fig. 10, and fig. 10 is a schematic partial sectional view of the housing assembly 20 in other embodiments of the present application, in which the inner sidewall of the middle frame 210 is formed with a first groove 213, and an end portion of the supporting member 230 is disposed in the first groove 213 and is bonded to an inner wall of the first groove 213, so as to further enhance the stability of the supporting member 230.

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. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of the feature.

Further, the inner sidewall of the middle frame 210 defines a first groove 213, in which the first groove 213 is substantially annular, and the outer periphery of the supporting member 230 is disposed in the first groove 213.
