A lower stepped area formed by the second stepped part 2032 and the first stepped part 2031 is contacted by the upper end of the bracket.
In the second camera module 2170 having the above configuration according to the present disclosure, the camera window 2240 may be attached to or detached from the outer housing 2220. Accordingly, the height of the second camera module 2170 can be minimized as compared to a conventional arrangement. In particular, the second camera module 2170 minimizes the height between the camera window 2240 and the lens module 2250. Accordingly, the second camera module 2170 can extend a viewing angle of the lens module 2250.
In the meantime, even though the distance between the camera window 2240 and the lens module 2250 in the second camera module 2170 becomes smaller, the sidewall 2020 of the outer housing 2220 can transfer an impact applied from the outside toward the wing 2030. The wing 2030 then transfers the impact to the back cover, rear cover, and bracket connected to the second camera module 2170. As a result, the second camera module 2170 can restrain the lens module 2250 from being damaged by an impact.
A method for mounting the second camera module 2170 according to the second embodiment of the present disclosure will now be described in more detail referring to FIGS. 6 and 7. FIG. 6 is a drawing illustrating a 3-dimensional structure of the second camera module 2170 of FIG. 4 mounted on a bracket 2310, and FIG. 7 is a sectional view illustrating a portion of the terminal in which the second camera module 2170 of FIG. 4 is mounted.
Referring now to FIGS. 6 and 7, the terminal according to the present disclosure may include a bracket 2310 for mounting the second camera module 2170. Further, the terminal may include a guide block 2311 so that the second camera module 2170 can be inserted into a predetermined area of the bracket 2310. The guide block 2311 may be provided in a shape corresponding to the shape of the inner housing 2210 of the second camera module 2170. For example, the inner housing 2210 of the second camera module 2170 may be provided in a hexahedron form, but other shapes are permissible.
Corresponding to this, the guide block 2311 may be provided in an intaglio hexahedron form so that the inner housing 2210 in hexahedron form can be settled. In particular, a sidewall of the guide block 2311 is provided with an open area for disposing a FPCB 2231 being connected to the camera PCB 2230 of the second camera module 2170.
Accordingly, if the FPCB 2231 is disposed in the open area of the guide block 2311, the second camera module 2170 can be inserted into the guide block 2311. Further, the guide block 2311 according to the present disclosure is formed so that the shape of block facing the outer housing 2220 corresponds to the shape of the outer housing 2220. Namely, a portion of the sidewall 2020 in the outer housing 2220 may be provided to protrude downwards from the second stepped part 2031 as shown in FIG. 7. Accordingly, the guide block 2311 may be provided with a sidewall in a concavo-convex shape so that the protruding portion of the sidewall 2020 can be settled.
With continued reference to FIGS. 6 and 7, the bracket 2310 provides a rigidity for the terminal and performs a role of blocking radio waves. The bracket 2310 is disposed between unit and a circuit module of the terminal, and provides support so that radio waves generated by the display unit do not introduce noise to the circuit module. Further, the bracket 2310 protects an image displayed in the display unit from being distorted by the radio waves generated from the circuit module. For this, the bracket 2310 may be formed with a special material such as magnesium (Mg). Alternatively, the bracket 2310 may be formed with various radio blocking materials according to a designer's intention.
A module mounting area 2305 of the bracket 2310 for mounting the second camera module 2170 may be formed with a separate material, such as a stainless steel (SUS). The area 2305 with a stainless steel can be formed thinner than that with a magnesium material, and has a characteristic of providing a specific rigidity. Accordingly, the module mounting area 2305 for mounting the second camera module 2170 can be formed thinner than the thickness of the bracket 2310 which is generally applied to the terminal.
Further, the module mounting area 2305 may be formed with a material that is different from the material used in other areas of the module. As described above, the display unit of the terminal is disposed at the bottom of the module mounting area 2305 of the bracket 2310. As a result, the area of the bracket 2310 for mounting the second camera module 2170 is formed relatively thinner than other areas in the terminal according to an embodiment of the present disclosure. Thus, the terminal according to an embodiment of the present disclosure can provide a slimmer design of a terminal by reducing a setting height of the second camera module 2170.
In the meantime, the second camera module 2170 can be provided in a fixed form by supporting the camera window 2240 with the outer housing 2220. Therefore, the assembly of the terminal according to the present disclosure may be performed by mounting the second camera module 2170 in the guide block 2311 of the bracket 2310, and simply connecting the rear cover 2302 and the back cover 2301. Namely, the process of assembling the terminal according to the present disclosure may include operations of forming the guide block 2311 in the bracket 2310, connecting the bracket 2310 and a display module 1400, setting the camera module 2170 in the guide block 2311 of the bracket 2310, coupling the rear cover 2302 to cover the edges of the camera module 2170, and coupling the back cover 2301. Here, the camera module 2170 is assembled so as to be exposed outwards through holes provided in the rear cover 2302 and the back cover 2301.
According to the embodiments of the present invention, the terminal may be manufactured by a method of installing the camera module so that a portion of the camera module is exposed as shown and described in one of the embodiments herein and laying the back cover thereon.
Accordingly, the terminal according to the embodiments of the present disclosure provides a production cost reduction by simplifying an assembly process comparing to the prior assembly process. The second camera module 2170 having the camera window 2240 may further include an adhesive layer 2241 between the cover unit 2010 of the outer housing 2220 and the camera window 2240 to fix the camera window 2240.
In the meantime, the rear cover 2302 is mounted in an upper area formed by the first stepped part 2031 and the second stepped part 2032. Here, a sponge 2303 may be disposed between the second stepped part 2032 and the rear cover 2302. The sponge 2303 is provided in a band form by surrounding the whole second stepped part 2032. The sponge 2303 performs a role of protecting an inflow of contaminants into the outer housing 2220.
As described above, in the terminal having a mounting structure of the second camera module 2170 according to the present disclosure, the sidewall 2020 of the outer housing 2220 is disposed by contacting with the guide block 2311 of the bracket 2310 as shown in the drawings. Accordingly, if an impact is applied from the outside, the impact is firstly transferred to the guide block 2311 of the bracket 2310 through the sidewall 2020 of the outer housing 2220. The transferred impact is then secondly transferred to the rear cover 2302 through the wing 2030 of the outer housing 2220. Here, the terminal according to the present disclosure may be provided with an impact absorbing layer between the sidewall 2020 and the guide block 2311 to reduce the impact transferred through the outer housing 2220. The impact absorbing layer may be configured with various materials having an elastic recovery function for absorbing an impact, such as a gum and a textile. The impact absorbing layer may be disposed and fixed at the bottom surface of the sidewall 2020 or on the top surface of the guide block 2311 of the bracket 2310.
The second camera module 2170 may not be provided with a separate deco structure as described in the mounting structure of the second camera module 2170 according to the second embodiment of the present disclosure, but may be provided so that the outer housing 2220 can replace the role of the deco. Accordingly, the terminal according to the present disclosure can provide a simplified assembly process by omitting the preparation and disposition of the deco.
The outer housing 2220 can be extruded by using a plastic material such as a PC and ABS for plating, and decorated through a post-processing such as a painting, plating, and depositing. The outer housing 2220 can be manufactured by a CNC finishing or die-casting of a metal including aluminum. Further, a surface appearance of the outer housing 2220 can be changed by a diamond cutting or spin hairline finishing. The outer housing 2220 can be variously colored and decorated through a post-finishing such as an anodizing. The above processes can be identically applied to the inner housing 2210. Accordingly, the outer housing 2220 and the inner housing 2210 of the second camera module 2170 according to the present disclosure may further include at least one of a painting layer, plating layer, and deposition layer according to the above finishing processes. Further, at least one of the outer housing 2220 and the inner housing 2210 of the second camera module 2170 according to the present disclosure may include at least one of a diamond-cut layer and a spin hairline finished layer. Further, at least one of the outer housing 2220 and the inner housing 2210 of the second camera module 2170 according to the present disclosure may include a colored layer at least in a portion of the housings. The above layers formed in the first camera module 1170 according to the previously described embodiment of the present disclosure may be applied to a third camera module 3170 which will be described hereafter.
FIGS. 8 and 9 are drawings illustrating a configuration of a third camera module according to a third embodiment of the present disclosure. In particular, FIG. 8 is a schematic drawing illustrating an appearance of the third camera module according to another embodiment of the present disclosure, and FIG. 9 is a sectional view illustrating a cross section along the line C-C′ of FIG. 8.
Referring now to FIGS. 8 and 9, the third camera module 3170 according to the present disclosure may include a camera PCB 3230 and a lens module 3250 having an opening at its upper side. The third camera module 3170 is configured with an integrated housing 3210 disposing a camera window 3240 in the open area. The third camera module 3170 is provided with an adhesive layer 3241 disposed between the camera window 3240 and the upper surface of the integrated housing 3210.
For the third camera module 3170 having the above configuration according to an embodiment of the present disclosure, the integrated housing 3210 may be manufactured by an extrusion method using a plurality of materials. The integrated housing 3210 is formed so that an edge of the housing is connected having a predetermined angle between a column and an upper end with a column, and provided with a rigid structure 3212 formed with a material different from those of sidewall structures 3211 and 3213.
The integrated housing 3210 may be configured with the sidewall structures 3211 and 3213 provided by applying an insert extrusion based on the rigid structure 3212. For this, the rigid structure 3212 may be formed with metals such as a SUS, aluminum, and alloys. The rigid structure 3212 is formed in a predetermined thickness, for example, 0.1 ̃0.4 mm to reinforce the rigidity of the third camera module 3170.
The rigid structure 3212 maintains a strong fixation of the sidewall structures 3211 and 3213 after the insert extrusion. For this, the rigid structure 3212 may include a plurality of penetration holes piercing from the front side to the rear side. The integrated housing 3210 according to the present disclosure is provided so that the sidewall structures 3211 and 3213 located at both sides are connected in the penetration hole area of the rigid structure 3212 by insert-extruding a plastic material based on the rigid structure 3212. In the structure of the integrated housing 3210, an example which the sidewall structures include a column connected to its upper end having a predetermined angle has been described, however the embodiments of the present disclosure are not limited to this. Namely, the side wall structures may be modified to various shapes such as a straight shape and a hook shape.
The inner sidewall structure 3211 may be provided in the rigid structure 3212, and the lens module 3250 can be mounted therein. Accordingly, the inner sidewall structure 3211 provides a space for mounting the lens module 3250. In particular, a mounting unit 3201 is provided in an open upper area of the inner sidewall structure 3211 so that the camera window 3240 can be safely mounted. A hole is formed in the center of the mounting unit 3201 so that the upper end of the lens module 3250 can be exposed to the outside. The mounting unit 3201 supports the edges of the camera window 3240. The edges of the adhesive layer 3241 and the camera window 3240 are arranged at the upper end of the mounting unit 3201. The outer sidewall structure 3213 is provided in the rigid structure 3212 and connected to a column having a predetermined angle.
The upper end of the outer sidewall structure 3213 can support the rigid structure 3212, and the lower end of the outer sidewall structure 3213 may be connected to a bracket. In the third camera module 3170 having the above structure, if an impact is applied from the outside, the impact is transferred through a deco disposed by arranging with the outer sidewall structure 3213 and the rigid structure 3212. The impact is then transferred to the bracket through the lower ends of the rigid structure 3212 and the outer sidewall structure 3213. The outer sidewall structure 3213 may be provided in a concavo-convex shape for an easiness and expansion of contact area when mounting the bracket. The sidewall structure 3213 may be formed with the same material as the inner sidewall structure 3211. For example, the sidewall structures 3211 and 3213 may be provided with a PC (Poly Carbonate), material combined with PC and GF (Glass Fiber), or ABS.
The third camera module 3170 according to the present disclosure may include a rigid structure 3212 disposed between the sidewall structures 3211 and 3213. Therefore, the third camera module 3170 according to the present disclosure reinforces the rigidity of the integrated housing 3210. For that reason, the third camera module 3170 according to the present disclosure can prevent components from being damaged by an impact applied from the outside. A mounting structure of the third camera module 3170 in the terminal according to the third embodiment of the present disclosure will be described in more detail referring to FIGS. 10 and 11.
FIG. 10 is a partial schematic drawing illustrating an appearance of the third camera module 3170 mounted on a bracket 3310 according to another embodiment of the present disclosure. FIG. 11 is sectional view illustrating a partial cross section of the terminal mounted with a rear cover after mounting a third camera module 3170.
Referring now to FIGS. 10 and 11, the third camera module 3170 according to the third embodiment of the present disclosure may be mounted in a guide block 3301 of the bracket 3310. The guide block 3301 is formed corresponding to the outer sidewall structure 3213 of the integrated housing 3210. Namely, the guide block 3301 is formed in a concavo-convex shape corresponding to the outer sidewall structure 3213 formed in a concavo-convex shape. A side of the guide block is provided in an open shape so that a FPCB connected to a PCB of the third camera module 3170 can be disposed. A module mounting area of the bracket 3310 for mounting the third camera module 3170 is formed thinner than adjacent areas. For this, the module mounting area 3305 may be provided with a material different from those of adjacent areas of the bracket 3310.
The rigid structure 3212 of the integrated housing 3210 is aligned to the outer side wall structure 3213. A sponge 3303 is disposed in an upper area of the integrated housing 3210 exposed outer wards. Here, the sponge 3303 performs a role of preventing contaminants from flowing into the third camera module 3170 or the rear cover 3302. A side of a deco 3307 is disposed on the top of the sponge 3303. The outer side wall structure 3213, a portion of the rigid structure 3212, the sponge 3303, and an edge of the deco 3307 are accordingly arranged and disposed. The arrangement heights of the sponge 3303 and the deco 3307 are formed similar to that of the camera window 3240.
The deco 3307 include a band part 3306, first extension 3308, and second extension 3304 as shown in the drawing. The band part 3306 is disposed on the top of the sponge so as not to be overlapped by the camera window 3240. The first extension 3308 is connected to the band part 3306, and extended in the direction to the outer side wall structure 3213. The second extension 3304 is extended in a predetermined length in the direction parallel to the rear cover 3302. Here, the first extension 3308 is provided to have a predetermined slope angle from an edge of the band part 3306. Accordingly, an impact transferred to the band part 3306 is transferred to the second extension 3304 through the first extension 3308 having a predetermined slope angle. The impact can be partially reduced by the first extension 3308 having the predetermined slope angle in a process of transferring the impact.
The rear cover 3302 is disposed to support the second extension 3304 of the deco 3307. For example, the rear cover 3302 can be disposed to expose the third camera module 3170 after mounting the third camera module 3170 into the bracket 3310. For this, the rear cover 3302 is provided in an open shape corresponding to the area of the third camera module 3170. The height of the upper part of the rear cover 3302 can perform a role of absorbing and relaxing an impact transferred from the second extension 3304.
The back cover 3301 may be provided to have a partially open area so that the third camera module 3170 can be exposed outer wards. In particular, the open area of the back cover 3301 may be provided so that the camera window 3240 and the deco 3307 can be exposed. The back cover 3301 is contacted by the front sides of the first extension 3308 and the second extension 3304. Accordingly, an impact transferred through the band part 3306 can be transferred to the front side of the back cover 3301.
As described above, the third camera module 3170 according to the third embodiment of the present disclosure is configured by an insert extrusion of the integrated housing 3210. The third camera module 3170 is provided so that the sidewall structures 3211 and 3213 are disposed at the inner and outer sides of the rigid structure 3212. In the third camera module 3170 having such a structure, an impact is absorbed by the integrated housing 3210, and the third camera module 3170 transfers the impact to the bracket 3310 and other structures. Through this process, damages of components can be minimized by providing the integrated housing 3210 based on the rigid structure 3212.
Further, the electronic device 100 having a camera module according to various embodiments of the present disclosure may include mobile communication terminals operating by communication protocols corresponding to various communication systems, and include, for example, hardware such as transmitters, receivers, transceivers, antennas microprocessor/controller comprising circuitry configured for operation, etc., and data communication equipment and multimedia equipment such as a PMP (Portable Multimedia Player), digital broadcast player, PDA (Personal Digital Assistant), music player (for example, MP3 player), portable game terminal, smart phone, notebook, and hand-held PC.
