[0054] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0055] 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 implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0056] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0057] As mentioned in the background technology, currently, control units such as the motherboard of electronic devices are arranged between the upper and lower shells, and an avoidance groove is set at the overlap of the upper shell and the lower shell. The FPC (Flexible Printed Circuit) for the antenna and the FPC for the side key are connected to the control unit through the avoidance groove.

[0058] However, the above structure may result in a gap between the sealing surfaces of the upper shell and the lower shell, thus affecting the IP waterproof rating of the smart device.

[0059] The IP waterproof rating is a standard set by the International Electrotechnical Commission (IEC) to indicate the dust and water protection performance of electronic products and equipment. The waterproof protection of electronic equipment is divided into 10 levels, represented by IPX0, IPX1, IPX2, etc. The larger the number, the higher the waterproof rating.

[0060] At present, for smartphones, the IPX7 and IPX8 waterproof grades (water pressure at a depth of 1 meter, equivalent to a space environment with a pressurized 0.1 MPa and no air leakage) are generally dominated by high-end mid-frame integrated models with higher prices. However, the waterproof grade of the lower-priced battery cover and front shell bottom models is only IPX3 (can prevent water jets. During the test, water was sprayed at a 60-degree angle and the device was not affected.), which is poor in waterproof performance and cannot meet the user's demand for waterproof performance.

[0061] For example, refer to Figures 1 to 3 As shown, in the existing bottom model of the battery cover wrapped front shell, the battery cover 1 is overlapped with the front shell 2, and the front shell 2 is arranged in the battery cover 1 (that is, the battery cover wrapped front shell structure), and the FPC board 3 of the antenna or the FPC board 3 of the side key needs to be introduced from the overlap of the battery cover 1 and the front shell 2 and electrically connected to the main board.

[0062] At this time, it is necessary to open a avoidance groove 4 on the front shell 2 or the battery cover 1 for the antenna FPC board 3 or the side key FPC board 3 to pass through, which will cause the sealing surface 5 between the front shell 2 and the battery cover 1 to have a gap and not be a complete sealing surface. Although a seal 6 is set between the front shell 2 and the battery cover 1, the water tested by IPX7 and IPX8 will penetrate into the interior of the whole machine along the step gap, so it can only pass the IPX3 non-water pressure test environment at most.

[0063] In view of the above problems existing in the prior art, the present invention provides a shell assembly and an electronic device. The shell assembly includes a first shell, a second shell, an FPC board, a first seal and a second seal. The second shell is connected to the first shell, and the first shell and the second shell are enclosed to form a separated first cavity and a second cavity. A threading hole is provided on the second shell, and the threading hole connects the first cavity and the second cavity. The first cavity is used to install a control module. The FPC board is arranged in the second cavity, and part of the FPC board extends into the first cavity through the threading hole. The first seal is arranged between the first shell and the second shell, and the second seal is used to fill the sealed threading hole. In this application, by providing a threading hole on the second shell, there is no need to provide an avoidance groove at the overlapping position of the first shell and the second shell, so that it forms a flat sealing surface, so that when the first seal is provided, no gap will be generated to achieve the waterproof level and airtightness requirements of IPX7 and IPX8.

[0064] The following is an introduction to exemplary application scenarios of the present invention.

[0065] The housing assembly provided by the present invention can be applied to electronic devices, such as smart phones, tablet computers, etc., and a smart phone is used as an example for illustrative description below. Specifically, the housing assembly provided by the present invention can achieve IPX7 and IPX8 waterproof level and airtightness requirements in the bottom model of the battery cover package front shell.

[0066] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0067] Reference Figures 4 to 6 As shown, a housing assembly 10 provided in the present application includes a first housing 100 , a second housing 200 , an FPC board 300 , a first sealing member 400 and a second sealing member 500 .

[0068] The second shell 200 is connected to the first shell 100 , and the first shell 100 and the second shell 200 are arranged to form a first cavity 101 and a second cavity 102 separated from each other. A threading hole 201 is opened on the second shell 200 , and the threading hole 201 connects the first cavity 101 and the second cavity 102 . The first cavity 101 is used to install the control module 20 .

[0069] The FPC board 300 is disposed in the second cavity 102 , and a portion of the FPC board 300 extends into the first cavity 101 through the threading hole 201 . The FPC board 300 is used to be electrically connected to the control module 20 .

[0070] The first sealing member 400 is disposed between the first shell 100 and the second shell 200 , and the second sealing member 500 is used to fill and seal the threading hole 201 .

[0071] It can be understood that the shell assembly 10 provided in the embodiment of the present application can be used in a smart phone, and the control module 20 (such as a motherboard) of the smart phone can be installed in a first cavity 101 formed by the first shell 100 and the second shell 200, and the FPC board 300 can be installed in the second cavity 102 formed by the first shell 100 and the second shell 200, and part of the FPC board 300 can pass through the threading hole 201 on the second shell 200 to extend into the second cavity 102 and be electrically connected to the control module 20.

[0072] Among them, a threading hole 201 is opened on the second shell 200, and the threading hole 201 is mainly used for allowing the FPC board 300 to enter the first cavity 101. In this way, there is no need to open an avoidance groove 121 at the overlapping position of the first shell 100 and the second shell 200. The overlapping position of the first shell 100 and the second shell 200 can form a flat sealing surface 221. In this way, when the first sealing member 400 is set at the overlapping position, no gap will be generated, so as to achieve the waterproof level and air tightness requirements of IPX7 and IPX8.

[0073] Furthermore, the threading hole 201 may be filled and sealed by the second sealing member 500 to ensure that the threading hole 201 will not leak due to the passage of the FPC board 300 .

[0074] In this way, the shell assembly 10 provided in the embodiment of the present application can also achieve the waterproof level and airtightness requirements of IPX7 and IPX8 for the bottom model of the battery cover and the front shell.

[0075] For example, refer to Figure 4 As shown, the first shell 100 can be a battery cover in a smart phone, and the second shell 200 can be a front shell in a smart phone. A threading hole 201 is provided on the front shell to form a flat sealing surface 221 at the overlapping position of the battery cover and the front shell.

[0076] Of course, the first shell 100 may also be the front shell of a smart phone, and the second shell 200 may also be the battery cover of a smart phone. A threading hole 201 is provided on the battery cover to form a flat sealing surface 221 at the overlapping position of the battery cover and the front shell. The embodiment of the present application does not impose any specific restrictions on this.

[0077] Exemplarily, the FPC board 300 may be an FPC for an antenna, an FPC for a side key, etc. The FPC board 300 may include a conductive layer (eg, a copper-based layer), a covering layer, etc., and the embodiment of the present application does not impose any specific limitation on this.

[0078] Reference Figure 5 and Figure 6 As shown, in some specific embodiments, a filling groove 202 is opened on the second shell 200 , and the filling groove 202 communicates with the second cavity 102 and the threading hole 201 .

[0079] The second sealing member 500 is filled in the filling groove 202 .

[0080] In the above embodiment, the FPC board 300 can enter the first cavity 101 through the filling groove 202 and the threading hole 201 in sequence. The filling groove 202 is mainly used to fill the second sealing member 500 to seal the threading hole 201 .

[0081] The filling slot 202 is located on the side facing the first side plate 120, and the filling slot 202 is connected to the second cavity 102 and the threading hole 201, so that when the second sealing member 500 is filled into the filling slot 202, it can prevent the second sealing member 500 from falling into the first cavity 101 and interfering with the control module 20. In addition, with such a structural setting, the redundant second sealing member 500 in the filling slot 202 can also be left in the threading hole 201 to prevent it from entering the first cavity 101.

[0082] The second sealing member 500 may be a colloid, such as a sealant, which is dispensed and sealed at the filling slot 202 to seal the threading hole 201 and prevent water from penetrating through the threading hole 201 .

[0083] Reference Figure 5 and Figure 6 As shown, in some specific embodiments, the cross-sectional area of ​​the filling groove 202 is larger than the cross-sectional area of ​​the threading hole 201 .

[0084] In the above embodiment, the cross-sectional area of ​​the filling groove 202 is larger, which can accommodate more second sealing members 500, ensuring more sufficient filling to achieve a satisfactory sealing effect. In addition, the narrow design of the threading hole 201 helps to limit excessive flow or overflow of the second sealing member 500, ensuring that it does not enter the first cavity 101 through the threading hole 201.

[0085] In some embodiments, the second sealing member 500 is a sealant.

[0086] In the above embodiment, the second sealing member 500 is mainly used to be filled in the filling groove 202 to seal the threading hole 201 .

[0087] Exemplarily, the sealant can be hot melt adhesive, photosensitive adhesive, optical adhesive, etc.

[0088] In some embodiments, reference Figure 5As shown, the first housing 100 includes a first main board 110 and a first side plate 120 disposed around the first main board 110 , and the second housing 200 includes a second main board 210 and a second side plate 220 disposed around the second main board 210 .

[0089] The second side plate 220 is connected to the first main plate 110 , and the first main plate 110 , the second side plate 220 and the second main plate 210 surround a first cavity 101 .

[0090] The first side plate 120 is connected to the second main plate 210 , and the first side plate 120 and the second side plate 220 are arranged to form a second cavity 102 .

[0091] The threading hole 201 is disposed on the second side plate 220 .

[0092] In the above embodiment, the first main board 110, the second side panel 220 and the second main board 210 are arranged to form a first cavity 101 with a larger volume. The first cavity 101 can be used to install the control module 20. The control module 20 can be the main board of the electronic device. The main board can be integrated with other functional components such as cameras, audio modules, sensors, wireless fidelity modules, radio frequency modules, Bluetooth modules, memory, processors, etc.

[0093] The first side plate 120 and the second side plate 220 are arranged to form a first cavity 101 with a smaller volume. The first cavity 101 can be arranged around the second cavity 102, and the FPC board 300 can be arranged in the first cavity 101 along the extension direction of the first cavity 101, so that the space can be fully utilized, thereby reducing the volume of the entire smartphone. At the same time, with such a structural arrangement, when the entire smartphone collides or falls, the FPC board 300 is not easily deformed, which can reduce damage.

[0094] Reference Figure 4 and Figure 6 As shown, in some specific embodiments, a sealing surface 221 is provided on a side of the second side plate 220 facing away from the second main plate 210 , and the surface of the sealing surface 221 is flat.

[0095] The first sealing member 400 is disposed on the sealing surface 221 .

[0096] In the above embodiment, the sealing surface 221 on the second side plate 220 is mainly used for the setting of the first sealing member 400. The flat sealing surface 221 can ensure that the first sealing member 400 is in close contact with it, thereby reducing the gap and effectively preventing water penetration to meet a higher IP waterproof level (such as IPX7 or IPX8).

[0097] It can be understood that the area corresponding to the sealing surface 221 of the first main board 110 and the second side plate 220 can form an abutment area for contacting the first seal 400. The surface of the abutment area is flat and can also play a role of close contact with the first seal 400 to improve the IP waterproof rating.

[0098] The first sealing member 400 may be arranged along the extension direction of the sealing surface 221 of the second side plate 220 . Exemplarily, the first sealing member 400 includes but is not limited to a sealing silicone ring, a sealing silicone pad, a sealing foam, a sealant, and the like.

[0099] Reference Figure 5 and Figure 6 As shown, in some specific embodiments, the threading hole 201 is disposed at an end of the second side plate 220 away from the first main plate 110 .

[0100] In the above embodiment, the threading hole 201 and the sealing surface 221 are respectively located at the opposite ends of the second side plate 220, so that the threading hole 201 and the sealing surface 221 are respectively located at the opposite ends of the second cavity 102, and the FPC board 300 can more reasonably utilize the internal space of the second cavity 102, so that the FPC board 300 can be stretched and arranged to avoid excessive bending, thereby reducing signal loss, structural damage or other electrical problems caused by excessive bending.

[0101] Reference Figure 5 and Figure 6 As shown, in some embodiments, the second main board 210 has a lap portion 211 extending outward.

[0102] The first side plate 120 is overlapped at the overlap portion 211 .

[0103] In the above embodiment, the overlapping portion 211 is mainly used to overlap the first side plate 120 , so that the first side plate 120 and the second side plate 220 are surrounded by the second cavity 102 .

[0104] Among them, refer to Figure 5 and Figure 6 As shown, the overlapping portion 211 protrudes outward toward a side away from the first housing 100 to form a mounting position, and the mounting position can be used to install the display assembly.

[0105] Exemplarily, the cross-section of the overlapping portion 211 may be in a rectangular, triangular, fan-shaped, trapezoidal, or other shape, and the embodiment of the present application does not impose too many limitations on this.

[0106] Reference Figure 5 As shown, in some embodiments, a side of the first side plate 120 facing the second side plate 220 is provided with an avoidance groove 121 for avoiding the FPC board 300 .

[0107] In the above embodiment, the avoidance groove 121 is provided to provide additional space to accommodate the FPC board 300 , thereby avoiding the problem of damage to the FPC board 300 or poor circuit contact due to narrow space.

[0108] Reference Figure 4 As shown, an electronic device provided in an embodiment of the present application includes a device body and a housing assembly 10 as described above.

[0109] The device body is disposed in the housing assembly 10 .

[0110] In the embodiment of the present application, since the electronic device adopts the housing assembly 10 in the above embodiment, it also correspondingly has the advantages and benefits brought by the above housing assembly 10, that is, good waterproof performance.

[0111] Exemplarily, the device body may include a display component, a control module 20, etc., and the embodiments of the present application do not impose too many restrictions on this.
