DETAILED DESCRIPTION OF THE INVENTION
Referring to FIGS. 1 to 1D, the housing mounting mechanism 20 for a portable electronic device according to an embodiment of the present invention includes a body 22, a latching member 24, a housing 26, and a first mounting member 28. Preferably, a second mounting member 30 is also included. The body 22 includes a plurality of lateral portions, such as a first lateral 32a and a second lateral 32b corresponding in position to the first lateral 32a. The first lateral 32a has at least one first mounting space 34, and the second lateral 32b has at least one second mounting space 36. The latching member 24 is movably mounted to the body 22 and is adjacent to the first lateral 32a of the body 22. The latching member 24 has at least one latching portion 38 adjacent to the at least one first mounting space 34. The housing 26 is detachably mounted to the body 22. The first mounting member 28 and the second mounting member 30 are connected to two corresponding laterals of the housing 26 respectively. The first mounting member 28 has at least one first mounting portion 40 corresponding to the at least one latching portion 38 of the latching member 24. The second mounting member 30 has at least one second mounting portion 42 corresponding to the at least one second mounting space 36 of the second lateral 32b of the body 22.
As shown in FIGS. 2 to 2B, the body 22 includes a first portion 44 and a second portion 46 opposite the first portion 44. The first portion 44 can be a front portion of the body 22 while the second portion 46 can be a rear portion of the body 22. At least one extending section 48 is provided adjacent to the first lateral 32a of the first portion 44. The latching member 24 is movably mounted in a space 54 between two wall portions 50 and 52 of the first portion 44 of the body 22. Preferably, the latching member 24 further has at least one auxiliary portion 56 configured to work in conjunction with the at least one latching portion 38, and the at least one auxiliary portion 56 and the at least one latching portion 38 jointly define a mounting opening 58 therebetween. The at least one extending section 48 can be mounted in the mounting opening 58. Also included is an elastic member 60 mounted between the latching member 24 and a wall 62 of the first portion 44 of the body 22.
As shown in FIG. 3, the at least one latching portion 38 of the latching member 24 has a latching section 64 and a first guiding surface 66 adjacent to the latching section 64. On the other hand, the at least one first mounting portion 40 of the first mounting member 28 has a mounting section 68 and a second guiding surface 70 adjacent to the mounting section 68. The latching member 24 can stay at a first position P1 with respect to the body 22 in response to the elastic force of the elastic member 60. To mount the housing 26 to the body 22, the operator moves the housing 26 toward the body 22.
As shown in FIG. 4, a force F is applied to the housing 26 such that the housing 26 is brought into contact with the body 22. During the process, the second guiding surface 70 of the at least one first mounting portion 40 of the first mounting member 28 corresponds to the first guiding surface 66 of the at least one latching portion 38 of the latching member 24. The first guiding surface 66 guides the at least one first mounting portion 40 of the first mounting member 28 in order for the housing 26 to displace along the first guiding surface 66 of the latching member 24 to a mounting position on the body 22. Preferably, at least one of the first guiding surface 66 and the second guiding surface 70 is an inclined surface. During the mounting process, the at least one first mounting portion 40 of the first mounting member 28 is pressed against the at least one latching portion 38 of the latching member 24 such that the latching member 24 is displaced from the first position P1 to a second position P2 with respect to the body 22 in a first direction D1. Meanwhile, the elastic member 60 generates an elastic force in response to the displacement of the latching member 24.
Once the housing 26 is displaced to the mounting position on the body 22, referring to FIG. 5, the latching member 24 is brought back to the first position P1 by the elastic force released by the elastic member 60, allowing the latching section 64 of the at least one latching portion 38 to lock the mounting section 68 of the at least one first mounting portion 40 of the first mounting member 28. In one embodiment, the respective contact surfaces of the latching section 64 and the mounting section 68 (i.e., the surfaces respectively with which the latching section 64 and the mounting section 68 contact each other) are inclined surfaces.
FIG. 6 shows the housing 26 mounted on the body 22. More specifically, the latching member 24 locks the first mounting member 28 in place. Preferably, the at least one second mounting portion 42 of the second mounting member 30 has a first section 72 and a second section 74 bent from the first section 72. The first section 72 is received in the at least one second mounting space 36 and the second section 74 is pressed against at least one fastening portion 76 (e.g., a recessed structure) of the body 22.
When it is desired to detach the housing 26 from the body 22, referring to FIG. 7 to FIG. 9, the operator inserts a tool 78 into a release hole 80 of the body 22 and thereby applies a pushing force to the latching member 24. Consequently, the latching member 24 is displaced from the first position P1 to the second position P2 in a direction D1 to separate the at least one first mounting portion 40 of the first mounting member 28 from the at least one latching portion 38 of the latching member 24. The operator can then detach the housing 26 from the body 22 to, for example, change a battery or SIM card of the portable electronic device.
In the second embodiment of the present invention as shown in FIG. 10, the contact surface of the latching section 200 of the at least one latching portion 38 of the latching member 24 is a horizontal surface, and the contact surface of the mounting section 202 of the at least one first mounting portion 40 of the first mounting member 28 is also a horizontal surface. The at least one latching portion 38 in this embodiment is equally capable of locking the at least one first mounting portion 40.
The present invention has been disclosed by way of the foregoing preferred embodiments, which, however, are not intended to be restrictive of the invention. The scope of patent protection sought by the applicant is defined by the appended claims.
