Description

Handheld electronic device

The present invention relates to a handheld electronic device, and more particularly to a handheld electronic device having a special shaped back cover.

The back side of a hand-held electronic device such as a general mobile phone or PDA is usually provided with a detachable back cover that can be opened for maintenance or battery replacement when internal electronic components are faulty or dead. The traditional back cover design is mostly separated from the body of the electronic device by sliding. However, for a back cover having a special shape (for example, a back cover of a gourd-like curved shape), it is easy to interfere with the body of the electronic device when sliding. Caused difficulties in the design of the organization. In view of this, how to design a convenient connection mechanism for a special-shaped back cover has become an important issue.

An embodiment of the present invention provides a handheld electronic device including a housing and a back cover. The housing has a receiving portion, and the receiving portion includes a first interval, a second interval, and a narrow interval, wherein the narrow interval The first and second intervals are connected, and the width of the narrow interval is smaller than the width of the first interval. The back cover has a first segment, a second segment and a narrow portion, wherein the narrow portion connects the first and second segments, and the width of the narrow portion is smaller than the width of the first segment. When the back cover is combined with the housing, the first and second sections and the narrow portion are respectively combined in the first and second sections and the narrow section, and when the first section is subjected to an external force, the first section is separated from the first direction. In a section, the back cover is displaceable from the first section to the second section, and slides in a second direction and away from the housing, wherein the first direction is substantially perpendicular to the long axis direction, and the second side The direction is substantially parallel to the long axis.

In an embodiment, when the housing further has a first engaging portion, and the back cover further has a second engaging portion, when the back cover is coupled with the housing, the first and second engaging portions are mutually engaged. Hehe.

In an embodiment, the first engaging portion is located in the first interval, and the second engaging portion is disposed in the first segment.

In an embodiment, the first engaging portion is a card slot, and the second engaging portion is a hook.

In an embodiment, the first and second sections and the narrow portion form a gourd structure.

In an embodiment, the width of the narrow portion is smaller than the width of the second portion.

In one embodiment, the narrow portion has a curved profile.

In an embodiment, the back cover and the casing are made of plastic material.

In an embodiment, the back cover has flexibility.

The above described objects, features, and advantages of the invention will be apparent from the description and appended claims

First, referring to FIG. 1A, a handheld electronic device 100 according to an embodiment of the present invention includes a housing 10 and a back cover 20, wherein the back cover 20 is detachably coupled to the back side of the housing 10, the foregoing back The cover 20 is made of plastic material or other flexible material, and the back cover 20 can also be composed of a soft material joining two rigid plastic sheets. As shown in FIG. 1A, the housing 10 is made of a plastic material, and a long-shaped receiving portion 123 is formed on the back side of the housing 10, and includes a first section 11, a second section 12, and a a narrow section 13 and the aforementioned narrow section 13 is connected to the first The second interval 11, 12.

Referring to FIGS. 1A and 1B again, the back cover 20 of the present embodiment has a golabash-shaped structure, which mainly includes a first segment portion 21, a second segment portion 22, and a narrow portion. twenty three. The back cover 20 may also be made of a soft and hard plastic material, wherein the narrow portion 23 has a curved outer shape on both sides and connects the first and second segments 21, 22, and the width of the narrow portion 23 is significantly smaller than the first The width of the second section 21, 22. As shown in Fig. 2, the first and second sections 21, 22 of the cover 20 have widths D1, D2, respectively, and the narrow section 23 between the first and second sections 21, 22 has a width d. Where d < D1 and d < D2, whereby a gourd-like structure can be presented. It should be understood that when the back cover 20 is coupled with the housing 10, the first and second sections 21, 22 and the narrow portion 23 are respectively coupled to the first and second sections 11, 12 and the narrow section, respectively. 13 inside.

In addition, as shown in FIG. 1A and FIG. 1B, a first engaging portion 101 is further disposed on the back side of the housing 10, and the second cover portion 201 is disposed on the back cover 20, and the back cover 20 and the housing are provided. When the 10 is combined, the first and second engaging portions 101, 201 are engaged with each other to prevent the back cover 20 from coming off. For example, the first engaging portion 101 may be a card slot disposed in the first section 11 , and the second engaging portion 201 may be a hook disposed on the first segment 21 , thereby The cover 20 is firmly coupled to the housing 10.

Referring to FIG. 3, when the back cover 20 is to be detached from the housing 10, an external force may first be applied to the first section 21 of the back cover 20 and lifted along a first direction A1. The second engaging portion 201 of the back cover 20 is separated from the first engaging portion 101 on the housing 10, and the first segment 21 of the back cover 20 is separated from the first section 11 on the back side of the housing 10 to form. As the third The state shown in the figure.

Referring to FIG. 4 again, after the first section 21 of the back cover 20 is lifted, an external force can be applied to move the back cover 20 toward a second direction A2, since the first section above the back cover 20 21 has been picked up, so the back cover 20 is no longer affected by the interference of the housing 10 when sliding, wherein the second direction A2 is substantially parallel to one of the long axis directions (Y-axis direction) of the handheld electronic device 100, and the second The direction A2 is substantially perpendicular to the first direction A1. In other words, as long as the first section 21 above the back cover 20 is lifted, the user can easily remove the back cover 20 from the housing 10 to facilitate subsequent maintenance or battery replacement.

Conversely, when the back cover 20 is to be re-bonded to the housing 10, it is only necessary to operate in the reverse order of the foregoing actions. First, the back cover 20 can be slid into the housing 10 in the reverse direction of the second direction A2. The back side of the receiving portion 123 is such that the lower half of the back cover 20 is firstly engaged in the receiving portion 123, and then an external force is applied to press the first portion 21 above the back cover 20 in the opposite direction of the first direction A1. In the first section 21 of the accommodating portion 123, the entire joining operation can be completed in this way.

Although the present invention has been disclosed above in the foregoing embodiments, it is not intended to limit the invention. Those skilled in the art having the ordinary skill in the art can make some modifications and refinements without departing from the spirit and scope of the invention. Therefore, the scope of the invention is defined by the scope of the appended claims.
