Description

Technical Field

[0001] The invention relates to a housing of an electronic device, in particular to a housing of an electronic device which is fastened by male and female screws. Background Art

[0002] Electronic devices, such as smart phones and handheld barcode scanners, most commonly use screw locking to limit or fix various electronic components in the assembly of the shell and internal electronic components, or to lock the upper and lower shells, or to lock the multi-layer shells. However, for more complex internal structures, or the locking of multi-layer shells, the screws are often staggered to lock different components, which also causes the space to make way for the screws and compress the setting space of other components. Even for antenna components that are easily affected by metal parts, the position or area that can be set may be reduced because of the need to avoid the setting position of the screws. Utility Model Content

[0003] In view of this, in one embodiment, a shell of an electronic device is provided, which is suitable for accommodating an antenna component. The shell of the electronic device includes a first shell component, a second shell component, a plurality of first screws, a decorative cover, and a plurality of second screws. The second shell component is correspondingly assembled to the first shell component, so that an accommodating space is formed between the first shell component and the second shell component, and the antenna component is arranged in the accommodating space. The second shell component is concavely provided with a plurality of screw locking grooves on the outer side surface relative to the accommodating space. Each first screw includes an outer thread segment and an inner thread segment, and the outer thread segment and the inner thread segment are connected. The outer thread segment passes through the second shell component from the outside of the second shell component and is screwed to the first shell component, and the inner thread segment is accommodated in a screw locking groove. The decorative cover is assembled to the second shell component. Each second screw passes through the decorative cover and is screwed to the inner thread segment of a first screw.

[0004] In some embodiments, the antenna component is disposed in the accommodation space on the side corresponding to where the decorative cover is located.

[0005] In some embodiments, the first housing member is provided with a plurality of locking columns in the accommodating space, each locking column corresponds to a screw locking groove, and the outer thread segment of the first screw passes through the screw locking groove and is screwed into the locking column.

[0006] In some embodiments, the antenna element is disposed around a plurality of locking posts.

[0007] In some embodiments, each locking column contains a metal internal thread column.

[0008] In some embodiments, the second housing member is provided with a maintenance hole at a location corresponding to the assembled decorative cover.

[0009] In some embodiments, each first screw has a cross groove on an end of the inner thread segment away from the outer thread segment.

[0010] In some embodiments, the depth of each screw lock groove recessed into the accommodating space is greater than or equal to the length of the inner thread segment of each first screw.

[0011] In summary, while the first screw is used to lock the first housing member and the second housing member in the vertical axis direction, a decorative cover can also be provided for screw locking. Therefore, there is no need to set screw holes for locking between the first housing member and the second housing member and between the decorative cover and the second housing member at different positions. By integrating some screw holes in the vertical direction, reducing the positions of the screw holes and the number of screws set on the plane, the area where the antenna member can be set can be increased. Furthermore, since the number and area of ​​metal screws set on the plane area are reduced, the impact of metal parts on the performance of the antenna member can also be reduced.

[0033] Please refer to Figures 1 to 3 As shown, Figure 1 is a schematic diagram of a housing of an electronic device according to an embodiment, Figure 2 is an exploded view of a housing of an electronic device according to an embodiment, Figure 3 An embodiment Figure 1 A cross-sectional view of the housing of the electronic device as seen by the section line. Figure 1 and Figure 2 It can be seen that the housing 100 of the electronic device is suitable for accommodating the antenna element 90. The housing 100 of the electronic device includes a first housing element 10, a second housing element 20, a plurality of first screws 30, a decorative cover 40 and a plurality of second screws 50. Figure 1 It is a three-dimensional schematic diagram viewed from the back of the housing 100 of the electronic device. The electronic device can be a smart phone, a PDA, a portable POS machine or various mobile terminals with barcode scanner functions, etc. The material and shape of the housing 100 can be designed as required.

[0034] The second housing 20 is correspondingly assembled to the first housing 10, so that a storage space S is formed between the first housing 10 and the second housing 20. The antenna 90 is disposed in the storage space S. The shape and size of the antenna 90 can be designed according to the requirements. In this embodiment, in order to achieve the best signal reception, the antenna 90 is disposed in a manner of as large an area as possible. Figure 2 It can be seen that the antenna element 90 is disposed in the accommodation space S on the side corresponding to the decorative cover 40. The size of the antenna element 90 almost covers the entire space on the decorative cover 40 except for the position of the metal parts such as screws. In other embodiments, it is not limited to this, but may even extend to other positions of the entire device.

[0035] The second housing 20 is provided with a plurality of screw lock grooves 21 on the outer side of the accommodating space S. Figure 3 As can be seen from the cross-sectional view, the screw lock groove 21 is from the outside of the second housing member 20 to the Figure 3 The bottom of the housing S is recessed, that is, it is recessed towards the direction of the accommodating space S.

[0036] Each first screw 30 includes an outer thread segment 31 and an inner thread segment 32, and the outer thread segment 31 and the inner thread segment 32 are connected. The outer thread segment 31 passes through the second outer shell member 20 from the outside and is screwed to the first outer shell member 10, and the inner thread segment 32 is accommodated in a screw locking groove 21. Figure 2Only one first screw 30 is decomposed for example. In actual application, the first screws 30 can be set at the four corners corresponding to the locking of the decorative cover 40. Alternatively, the first screws 30 can be set only at the left and right positions corresponding to the front end side of the second housing member 20 to lock the first housing member 10, the second housing member 20 and the decorative cover 40 at the corners at the same time.

[0037] The decorative cover 40 is assembled on the second housing member 20 , and each second screw 50 passes through the decorative cover 40 and is screwed to the inner thread segment 32 of one of the first screws 30 .

[0038] Thus, while one end of the first screw 30 is used to lock the first housing member 10 and the second housing member 20 in the vertical axis direction, the other end of the first screw 30 can also provide the second screw 50 for locking the decorative cover 40 for screw locking. Therefore, there is no need to set screw holes for locking between the first housing member 10 and the second housing member 20 and between the decorative cover 40 and the second housing member 20 at different positions. By integrating some screw holes in the vertical direction, reducing the positions of the screw holes and the number of screws set on the plane, the area where the antenna member 90 can be set can be increased. Furthermore, since the number and area of ​​the metal screws set on the plane area are reduced, the influence of metal parts on the performance of the antenna member 90 can also be reduced.

[0039] Depend on Figure 2 It can be seen that the first outer shell member 10 is provided with a plurality of locking columns 11 in the accommodating space S, and each locking column 11 corresponds to a screw lock groove 21. The outer thread segment 31 of the first screw 30 passes through the screw lock groove 21 and is screwed into the locking column 11. In some embodiments, an internal thread can be directly provided on the inner side of the locking column 11 for the outer thread segment 31 to be screwed. In some cases, if the first outer shell member 10 and the second outer shell member 20 are made of plastic injection molding, or only the positions or components corresponding to the screw lock groove 21 and the locking column 11 are made of plastic injection molding, directly forming the internal thread may easily cause broken teeth under repeated unlocking. To avoid this situation, in the present embodiment, a metal internal thread column 111 is provided in each locking column 11. The metal internal thread column 111 can be arranged in the hollow locking column 11 by tight fitting, bonding or clamping.

[0040] Depend on Figure 2 and Figure 3 It can be seen that the antenna element 90 is disposed around the locking column 11. In this case, the locking column 11 can be made of non-metallic materials to avoid affecting the performance of the antenna element 90. By allowing the antenna element 90 to be disposed around the locking column 11, the area where the antenna element 90 can be disposed can be increased, thereby improving the transmission and reception performance of signals.

[0041] Depend on Figure 2It can be seen that the second housing 20 has a maintenance hole 22 at the location corresponding to the decorative cover 40. Components that need to be replaced as needed, such as expansion components, or consumable components that are easily damaged during use can be installed in the accommodation space S corresponding to the maintenance hole 22. When it is necessary to replace a component, the decorative cover 40 can be removed by simply removing the second screw 50 corresponding to the decorative cover 40, so that the component in the accommodation space S can be disassembled or assembled through the maintenance hole 22.

[0042] Then, by Figure 2 It can be seen that each first screw 30 has a cross groove 33 at the end of the inner thread segment 32 away from the outer thread segment 31. Thus, when the first screw 30 is to pass through the second housing member 20 and screwed to the first housing member 10, a slotted screw or a cross screw can be used to engage in the cross groove 33 for rotation, thereby increasing the convenience of assembly.

[0043] In addition, by Figure 3 It can be seen that the depth D of each screw lock groove 21 recessed into the accommodation space S is greater than or equal to the length d of the inner thread segment 32 of each first screw 30. Thus, when the first screw 30 is accommodated in the screw lock groove 21 from the outside of the second housing 20, it can be completely accommodated in the screw lock groove 21 without being exposed from the outside of the second housing 20. In this way, the surface covered by the decorative cover 40 can be made flatter.

[0044] Although the present disclosure has been disclosed in some embodiments as above, it is not intended to limit the present disclosure. Any person with ordinary knowledge in the relevant technical field can make some changes and modifications without departing from the spirit and scope of the present disclosure. Therefore, the scope of patent protection of the present utility model shall be subject to the scope defined by the attached claims.
