FIG. 1 illustrates an embodiment of an electronic device housing 100 of the disclosure. The electronic device housing 100 can include a first housing 10, a second housing 30, three limiting members 50, and two fastening members 70. The first housing 10 and the second housing 30 can be adhered together and fastened by the fastening members 70. The limiting members 50 can limit a relative position of the first housing 10 and the second housing 30 during the fastening of the first housing 10 and the second housing 30, such that a gap defined between the first housing 10 and the second housing 30 can be even. In the illustrated embodiment, the first housing 10 can be an outer housing and made of aluminum. The second housing 30 can be a support member configured to support components of the electronic device. The second housing 30 can be made of copper. In alternative embodiments, the first housing 10 and the second housing 30 can be made of other materials. In an alternative embodiment, the second housing 30 can be made of plastic.
FIG. 2 illustrates that the first housing 10 can include a bottom wall 11, a sidewall 13, and a top wall 15. The sidewall 13 can be curved and connect the bottom wall 11 to the top wall 15. The bottom wall 11 and the top wall 15 can be substantially parallel to each other. The bottom wall 11, the sidewall 13, and the top wall 15 can cooperatively define a receiving chamber 17. The receiving chamber 17 can be configured to receive the second housing 30 and components of the electronic device. The sidewall 13 of the first housing 10 can define an opening 131. The opening 131 can communicate with the receiving chamber 17 and be configured to partially receive the second housing 30.
The top wall 15 of the first housing 10 can define three limiting holes 151 and two fastening holes 153. The limiting holes 151 and the fastening holes 153 can communicate with the receiving chamber 17. Both of the limiting holes 151 and the fastening holes can be stepped holes. The limiting holes 151 can be arranged at three points of an imaginary triangle, as opposed to a straight line. The fastening holes 153 and one of the three limiting holes 151 can be arranged in a straight line. The limiting holes 151 can be configured to couple to the limiting members 50. The fastening holes 153 can be configured to couple to the fastening members 70.
FIGS. 2 and 3 illustrate the second housing 30 of the disclosure. The second housing 30 can be cuboid and be configured to support electrical elements of the electronic device. In the illustrated embodiment, the second housing 30 can be configured to support an I/O connector (not shown). The second housing 30 can be received in the receiving chamber 17 of the first housing 10. To ensure an accuracy of position of the I/O connector, the second housing 30 can be accurately assembled to the first housing 10.
The second housing 30 can include a bottom surface 31, a top surface 33, and four side surfaces 35. The bottom surface 31 can be substantially parallel to the top surface 33. The four side surfaces 35 can be coupled end to end in order. Each side surface 35 can be coupled to the top surface 33 and the bottom surface 31. The top surface 33 of the second housing 30 can define two fixing holes 331 corresponding to the two fastening holes 153. The fixing holes 331 can be configured to couple with the fastening members 70. A protruding portion 351 can protrude from one of the side surfaces 35 adjacent to the sidewall 13 of the first housing 10. The protruding portion 351 can be received in the opening 131 and partially be exposed from the opening 131. The bottom surface 31, the top surface 33, and the side surfaces 35 of the second housing 30 can be covered with thermal curing glue. Thus the bottom surface 31 can be adhered to the bottom wall 11. The top surface 33 can be adhered to the top wall 15. The side surfaces 35 can be adhered to the sidewall 13.
The three limiting members 50 can be inserted and threaded in the three limiting holes 151 of the top wall 15. The limiting members 50 can resist against the top surface 33 of the second housing 30. The limiting members 50 can be received in the corresponding limiting holes 151. Because the limiting holes 151 are not arranged in a straight line, a gap between the top surface 33 and the top wall 15 can be even when the limiting members 50 resist against the top surface 33. Thus, a gap between the bottom surface 31 and the bottom wall 11 can be even. In the illustrated embodiment, the limiting members 50 can be screws.
The fastening members 70 can be inserted in the fastening holes 153 of the top wall 15, respectively, and threaded into the fixing holes 331. Each fastening member 70 can be received in the corresponding fastening hole 153 and into the corresponding fixing hole 331. In the illustrated embodiment, the fastening members 70 can be screws.
FIG. 4 illustrates a method for manufacturing a housing of electronic device 200.
In block 101, a first housing can be provided. The first housing can include a bottom wall, a sidewall, and a top wall. The bottom wall, the sidewall, and the top wall can cooperatively define a receiving chamber. The sidewall of the first housing can define an opening. The top wall of the first housing can define three limiting holes and two fastening holes.
In block 102, a second housing can be provided. The second housing can include a bottom surface, a top surface, and four side surfaces. The top surface of the second housing can define two fixing holes corresponding to the two fastening holes. A protruding portion can protrude from one of the side surfaces corresponding to the opening.
In block 103, the bottom surface, the top surface, and the four side surfaces can be covered with thermal curing glue. The second housing 30 can be assembled to the receiving chamber. Thus the bottom surface can contact with the bottom wall. The top surface can contact with the top wall. The side surfaces can contact with the sidewall.
In block 104, the thermal curing glue can be heated and then cooled. The thermal curing glue can be cured. Thus, the bottom surface can be adhered to the bottom wall. The top surface can be adhered to the top wall. The side surfaces can be adhered to the sidewall.
In block 105, three limiting members can be provided. The limiting members can be inserted into the limiting holes and threaded with the limiting holes. The limiting members can resist against the top surface of the second housing.
In block 106, two fastening members can be provided. The fastening members can be inserted into the fastening holes and threaded into the fixing holes.
In an alternative embodiment, the fastening members can be assembled to the fastening holes and the fixing holes before the thermal curing glue is cured. For example, the block 104 can be processed after the block 106.
In an alternative embodiment, a number of the limiting members 50 can be one or more, and the limiting holes 151 can be one or more corresponding to the limiting members 50. A number of the fastening members 70 can be one or more, and the fixing holes 331 can be one or more corresponding to the number of the fastening members 70. The side surfaces 35 do not contact and adhere to the sidewall 13. Thus the thermal curing glue covers only the top surface 33 and the bottom surface 31.
It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes can be made thereto without departing from the spirit and scope of the embodiments or sacrificing all of its material advantages.
