Referring to fig. 1-3, the present application provides a housing assembly 100 and an electronic device 200 including the same. Specifically, the electronic device 200 may be a mobile phone, an IPad, a smart wearable device, a digital audio/video player, an electronic reader, a handheld game console, a vehicle-mounted electronic device, a digital camera, a printer, a flash drive, and the like. The housing assembly 100 includes a middle frame 10, a gel 20 disposed on the middle frame 10, and a housing 30 adhered to the middle frame 10 by the gel 20.

Referring to fig. 4, in an embodiment, in the present application, the housing 30 is a back shell of the electronic device 200, which may also be called a battery cover. The housing 30 defines a through-slot 32, and the through-slot 32 is used for disposing a camera assembly 40, such as a rear camera assembly of the electronic device 200, or some sensor assembly (not shown). The camera assembly 40 or sensor assembly is configured to have a portion exposed on an exterior surface of the electronic device 200. The camera assembly 40 is used for acquiring pictures outside the electronic device 200 to realize functions of taking pictures or taking videos. The sensor assembly is used for receiving light outside the electronic device 200, or infrared rays of the user, or functions of contacting with the skin of the user to measure parameters of the human body.

Specifically, one or more through slots 32 may be formed in the housing 30, and the electronic device 200 may only be provided with the camera assembly 40 or only with the sensor assembly in the through slot 32 of the housing 30, or may be provided with both the camera assembly 40 and the sensor assembly. In the embodiment where the camera head assembly 40 and the sensor assembly are provided at the same time, the camera head assembly 40 and the sensor assembly may be respectively accommodated in different through slots 32, or may be accommodated in the same through slot 32, which is not particularly limited.

It will be appreciated that the camera assembly 40 or sensor assembly is disposed at a position that is off-top of the entire electronic device 200, and also near the sides of the housing 30, such that the width a of the housing 30 from the sides adjacent to the through slots 32 to the positions where the through slots 32 are opened is small. Since the electronic device 200 is required to be light and thin, the thickness of the housing 30 is relatively small, and the portion of the housing 30 from the side adjacent to the through slot 32 to the position where the through slot 32 is opened is relatively weak. On the other hand, the shell 30 is fixed to the middle frame 10 by the adhesive 20, and since the width a from the side of the shell 30 adjacent to the through groove 32 to the position where the through groove 32 is opened is small (as shown in fig. 4), the coated adhesive 20 is easily spread after being squeezed, so that the adhesive 20 is fully distributed over all or most of the area from the side of the shell 30 adjacent to the through groove 32 to the position where the through groove 32 is opened. After the glue body 20 is solidified, the side edge of the shell 30 adjacent to the through groove 32 to the position where the through groove 32 is formed is filled and fixed by the glue body 20, and when the electronic device 200 falls, a deformation space does not exist, and meanwhile, the position has a small width, a small thickness and is relatively fragile, so that the position has weak impact strength and is easy to crack or even break.

Referring to fig. 5, the middle frame 10 is an important carrier in the electronic device 200 for carrying a circuit board, a battery, and the like in the electronic device 200. The edge position of the middle frame 10 is provided with a first groove 12, a position of the middle frame 10 close to the through groove 32 is provided with a limiting member 14, the position of the middle frame 10 close to the through groove 32 is divided into a first area 16 and a second area 18 by the limiting member 14, and the first area 16 is clamped between the first groove 12 and the limiting member 14.

Further, in one embodiment, because the thickness of the camera assembly 40 or sensor assembly is greater than the thickness of the housing 30, the through slot 32 is not deep enough to accommodate the camera assembly 40 or sensor assembly. Therefore, in this embodiment, the accommodating groove 19 is formed in the middle frame 10, the accommodating groove 19 is opposite to the through groove 32 and is communicated with the through groove, and the end portion of the accommodating groove 19 surrounded by the middle frame 10 is in bending transition, so that the end portion of the accommodating groove 19 surrounded by the middle frame, that is, the inner wall, is extended and expanded as much as possible according to the arrangement of other surrounding components, so that the middle frame 10 has a larger area as much as possible at a position close to the through groove 32, and further the strength of the position of the middle frame is increased.

In embodiments where the middle frame 10 has a better thickness near the through slots 32, the second region 18 may also be hollowed out, so that the side of the shell 30 adjacent to the through slots 32 has a larger deformation space to the position where the through slots 32 are opened.

The colloid 20 is used for adhering and fixing the middle frame 10 and the shell 30, the middle frame 10 adopts the above structure, therefore, when the colloid 20 is coated, the colloid 20 can be coated on the first area 16, then the shell 30 is covered on the middle frame 10, so that the shell 30 extrudes the colloid 20, the colloid 20 is extruded by the shell 30 and then diffuses towards two sides, one side diffuses towards the first groove 12 and enters the first groove 12, the other side diffuses towards the limiting piece 14, so that the colloid 20 at least covers the first groove 12 and at least part of the first area 16 to adhere the middle frame 10 and the shell 30. The glue body 20 does not spread to the second region 18 due to the blocking of the position restricting member 14, so that a gap exists between the case 30 and the middle frame 10 at a position opposite to the second region 18. When the electronic device 200 falls or collides, the position of the housing 30 opposite to the second region 18 can be slightly deformed by the gap to absorb the external force generated at the position in the falling or collision process, so as to solve the problem that the side of the housing 30 adjacent to the through groove 32 is easy to crack or even break when falling or colliding to the position where the through groove 32 is formed.

It will be appreciated that, with the above configuration, a machine or worker can apply the glue 20 as close to the first recess 12 as possible, so that the first recess 12 can absorb more glue 20 than the first region 16. In other embodiments, the glue 20 may be applied to the middle of the first region 16 or a position away from the first groove 12, as long as the glue 20 does not enter the second region 18 under the action of the limiting member 14, which is not particularly limited. In this embodiment, the colloid 20 is disposed around the middle frame 10 for a circle to form a closed circle, so that the colloid 20 can firmly fix the casing 30 on the middle frame 10, and the colloid 20 can form a waterproof ring to prevent water vapor from entering the electronic device 200.

Alternatively, in various embodiments, the glue 20 may be at least one of foam glue, PET substrate glue, and glass glue. When the above-listed colloids are used, the colloid 20 does not become extremely hard after solidification, and the deformation of the shell 30 under a force at a position close to the through groove 32 is facilitated to provide a buffering effect. When the colloid 20 adopts the foam cotton, the foam cotton is internally provided with a capillary hole structure and can be further compressed when being stressed, so that the colloid 20 made of the material can reduce the diffusion area of the colloid 20 in the direction of the second area 18 when being stressed. In other embodiments, the colloid 20 may be made of other materials, which is not limited in detail.

Optionally, in an embodiment, the limiting member 14 is disposed near the first groove 12, so that the area of the first region 16 is smaller than the area of the second region 18. This can increase the amount of space available for deformation when the housing 30 is impacted and is less likely to crack or break.

In different embodiments, the limiting member 14 on the middle frame 10 may be a boss or a second groove, where fig. 3 shows that the limiting member 14 is a boss, and fig. 5 and 6 show that the limiting member 14 is a second groove. The convex plate is used for preventing the glue body 20 from being extruded and spreading to the second area 18, and the second groove absorbs the glue body 20 into the second groove in an absorption mode, so that the glue body 20 is prevented from spreading to the second area 18. Specifically, the limiting member 14 may be a straight strip or a curved strip.

Alternatively, in an embodiment, the cross-sectional width of the second groove is gradually increased from the side close to the housing 30 to the side far from the housing 30, that is, the structure is large at the bottom and small at the top. Such structural design can make the second recess can hold more colloid 20, guarantees better that colloid 20 can not get into the second region 18, can also guarantee simultaneously that the colloid 20 area that exposes at second recess opening part is less, guarantees to have the deformation space of more areas between casing 30 and the second region 18. For example, in an embodiment, the cross section of the second groove has a trapezoidal structure, and other embodiments may also have other regular or irregular shapes, which is not limited in particular.

Referring to fig. 7, further, in another embodiment, a third groove 11 and/or a blind hole 13 is further disposed on a portion of the middle frame 10a close to the through slot 32, and the third groove 11 and/or the blind hole 13 is disposed adjacent to the limiting member 14. In particular, the third recess 11 or the blind hole 13 may be located in the first region 16 and/or the second region 18. When the third grooves 11 and/or the blind holes 13 are located in the first area 16, the glue 20 is first filled into the third grooves 11 and/or the blind holes 13 when being extruded to run toward the second grooves or the bosses, so that the glue 20 is prevented from excessively spreading through the second grooves or the bosses to enter the second area 18. When the third groove 11 and/or the blind hole 13 are located in the second region 18, in the case that more glue 20 is applied and the stopper 14 is not stopped, the glue 20 spreading over the stopper 14 first enters the third groove 11 and/or the blind hole 13, so as to minimize the area of the glue 20 spreading over the second region 18.

Alternatively, in different embodiments, the third groove 11 may have the same length as the second groove, or a smaller length than the second groove. The number of the third grooves 11 may be one or more. The blind hole 13 may be one or more, and is not particularly limited.

Referring to fig. 8, optionally, in another embodiment, a plurality of supporting portions 50 are disposed on the first region 16 of the middle frame 10b, and the shell 30 abuts on the supporting portions 50. Specifically, the supporting portion 50 may be a plurality of protruding strips and/or protruding points. By adopting the structure, the supporting part 50 plays a supporting role for the shell 30, but not completely supported by the glue 20, so that the glue 20 has a certain thickness, and simultaneously, a gap between the position corresponding to the second region 18 of the middle frame 10 and the shell has a larger width, thereby ensuring that the position of the shell 30 corresponding to the second region 18 has a better deformation space.

According to the application, the position of the middle frame 10 close to the through groove 32 is provided with the limiting piece 14, so that the colloid 20 cannot spread to the second region 18 under the action of the limiting piece 14, and a gap exists between the middle frame 10 and the position of the shell 30, which is opposite to the second region 18. When the electronic device 200 falls or collides, the position of the housing 30 opposite to the second region 18 can be slightly deformed by the gap to absorb the external force generated at the position in the falling or collision process, so as to solve the problem that the side of the housing 30 adjacent to the through groove 32 is easy to crack or even break when falling or colliding to the position where the through groove 32 is formed. The housing assembly 100 is simple in structure, good in effect, capable of not increasing the size of the electronic device 200, not increasing the cost and high in practicability.

The above description is only for the purpose of illustrating embodiments of the present application and is not intended to limit the scope of the present application, and all modifications of equivalent structures and equivalent processes, which are made by the contents of the specification and the drawings of the present application or are directly or indirectly applied to other related technical fields, are also included in the scope of the present application.
