Description

Technical Field

[0001] The present application relates to a housing assembly and an electronic device having the housing assembly. Background Art

[0002] With the continuous advancement of science and technology, electronic devices are gradually developing towards large screens and high integration, which poses a great challenge to the battery life of electronic devices. As we all know, to improve the battery life of electronic devices, it is necessary to increase the capacity of the battery. However, increasing the capacity of the battery means increasing the volume of the battery, and under the trend of thinning and lightweight electronic devices, the thickness of the entire electronic device is strictly limited. Therefore, how to reduce the space occupancy rate of other components in electronic devices is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0003] In view of this, it is necessary to provide a housing assembly with lower space occupancy and larger accommodation space.

[0004] The present application also provides an electronic device having the housing assembly.

[0005] A shell assembly includes a first shell and a second shell arranged in the first shell, the first shell has a groove on its surface facing the second shell, the second shell includes a first side plate and a second side plate that are oppositely arranged, a bottom plate and a buckle, the first side plate and the second side plate are respectively arranged on both sides of the bottom plate and jointly form a receiving space; the first side plate and the second side plate are respectively connected to the first shell, the buckle is arranged on the first side plate or on the second side plate, and is received in the groove.

[0006] An electronic device comprises a wire and the above-mentioned housing assembly, wherein the wire is arranged in the buckle.

[0007] In summary, by hiding the buckle in the groove of the first shell, the space of the buckle is compressed, thereby reducing the space occupancy rate of the second shell in the first shell. In addition, the space of the receiving space is increased in disguise, thereby providing more space for the battery. In addition, the setting of the buckle also plays the role of fixing the wires, standardizing the arrangement of the wires, and preventing jumpers. BRIEF DESCRIPTION OF THE DRAWINGS

The second snap-fitting portion 1232 and the first snap-fitting portion 1231 are arranged opposite to each other and spaced apart to form an opening 1234. The opening 1234 faces the second side wall 112. The opening and closing size of the opening 1234 can be adjusted according to the first snap-fitting portion 1231 and the second snap-fitting portion 1232. The number of the buckles 123 can be adaptively adjusted according to actual needs, and can be one, two, three, four, etc.

[0073] In other embodiments, the buckle 123 can be formed by bending the second portion 1222 .

[0074] In this embodiment, Figure 4 and Figure 5 The second side plate 124 includes a third sub-portion 1241 and a fourth sub-portion 1242. The third sub-portion 1241 is disposed at the edge of the bottom plate 121.

The second side plate 124 is substantially in an inverted L shape.

[0075] Specifically, the second side wall 112 includes a second inner surface 1121 and a second outer surface 1122 disposed opposite to the second inner surface 1121. The second inner surface 1121 faces the first side wall 111. A convex portion 115 is convexly disposed on the second inner surface 1121. In this embodiment, the convex portion 115 is generally strip-shaped, disposed at the lower end of the second inner surface 1121, and extending from one of the third side walls 113 to the other third side wall 113. Figure 7 , the convex portion 115 includes a second connecting surface 1151 and a third side surface 1152 and a fourth side surface 1153 which are arranged back to back. The second connecting surface 1151 is connected between the third side surface 1152 and the fourth side surface 1153. The third subdivision 1241 is opposite to and spaced from the second connecting surface 1151, and also forms the assembly gap to further realize the assembly of the second shell 12 and the first shell 11. The spacing between the third subdivision 1241 and the second connecting surface 1151 is 0.05 mm. The fourth subdivision 1242 is connected to the third side surface 1152. In one embodiment, the connection of the third side surface 1152 of the fourth subdivision 1242 is achieved by a welding process.

[0076] Further, Figure 4 and Figure 5 , the second shell 12 further includes a connecting member 126. The connecting member 126 is connected to at least one of the third side walls 113 to strengthen the connection between the second shell 12 and the first shell 11. In this embodiment, the connecting members 126 are connected to both of the third side walls 113. The number of the connecting members 126 can be adaptively adjusted according to actual conditions, and can be one, two, three, etc.

[0077] In this embodiment, the connecting member 126 includes a first connecting portion 1261 and a second connecting portion 1262. The first connecting portion 1261 is disposed at the edge of the bottom plate 121. The second connecting portion 1262 extends from the side of the first connecting portion 1261 away from the bottom plate 121 toward the third side wall 113 and abuts against the third side wall 113. The connecting member 126 is generally in an inverted L shape. In one embodiment, the connecting member 126 is welded to the third side wall 113 through the second connecting portion 1262.

[0078] The second shell 12 is firmly welded to the first shell 11 by using the first side plate 122 , the second side plate 124 , and the connecting piece 126 , so that the shell assembly 10 has high welding strength and firm welding under thrust test, thus meeting product requirements.

[0079] In other embodiments, the connector 126 may be omitted.

[0080] Ginseng Figure 3 , Figure 4 and Figure 5 The electronic device 100 further includes a wire 20. In this embodiment, the wire 20 is an RF cable (Radio-Frequency Line). The wire 20 is disposed in the buckle 123 through the opening 1234 to fix the wire 20, standardize the arrangement of the wire 20, and prevent wire jump.

[0081] Further, Figure 2 , Figure 3 and Figure 4 The electronic device 100 further includes a battery 30. The battery 30 is received in the receiving space 125.

[0082] In this embodiment, the wire diameter of the wire 20 is 1.02 mm, the thickness of the buckle 123 is 0.58 mm, and the material of the second housing 12 is stainless steel, with a thickness of 0.3 mm.

[0083] In view of the fact that the wiring paths of electronic devices in the prior art are generally arranged in the receiving space 125, the space of the battery 30 in the receiving space 125 will be compressed. In addition, the thickness of the aluminum alloy middle frame structure directly below the battery in the prior art is generally 0.6mm. Therefore, if the receiving space 125 of the electronic device in the prior art can only accommodate a battery 30 of 83.5mm*60.2mm*3.85mm (length*width*height), the power of the battery 30 is 3230mAh. Then, compared with the prior art, the structural design of the groove 13 in this embodiment frees up 1.6mm (i.e., the wire diameter of the wire 20 is 1.02mm + the thickness of the buckle 123 is 0.58) of space in the width direction of the receiving space 125. In addition, in the height direction, the thickness of the second shell 12 in the prior art is thinned by 0.3mm compared with the middle frame structure of the prior art. Then, in this embodiment, the receiving space 125 can accommodate a battery 30 of 83.5mm*61.8mm(60.2mm+1.6mm)*4.15mm(3.85mm+0.3mm)(length*width*height), and the power of the battery 30 can reach 3585mAh. It can be seen that the power of the battery 30 in this embodiment is increased by 11% compared with the prior art, that is, (3585mAh-3230mAh) / 3230mAh=11%.

[0084] In summary, this embodiment hides the buckle 123 in the groove 13 of the first shell 11 to compress the space of the buckle 123, thereby reducing the space occupancy rate of the second shell 12 in the first shell 11. In addition, the space of the receiving space 125 is also increased in disguise, thereby providing more space for the battery 30, thereby increasing the battery power. In addition, the setting of the buckle 123 also plays the role of fixing the wire 20, standardizing the arrangement of the wire 20 and preventing wire jump.

[0085] The above embodiments are only used to illustrate the technical solution of the present application and are not intended to limit it. Although the present application has been described in detail with reference to the preferred embodiments, a person of ordinary skill in the art should understand that the technical solution of the present application may be modified or replaced by equivalents without departing from the spirit and essence of the technical solution of the present application.
