Portable electronic device

The present invention relates to a portable electronic device, and more particularly to a portable electronic device that rotatably couples two modules.

Generally, in order to allow two objects to rotate relative to each other, a pivot is often used to couple between the two objects. The following is an example of a notebook computer. At present, the general notebook computer system includes a keyboard module and a display module. The display module can be rotated relative to the keyboard module by a pivot to allow the user to adjust the angle of the display module as needed.

The pivot is usually fixed directly to the inner side surface of the display module and the inner side surface of the keyboard module by screwing. However, this configuration method causes the display module and the keyboard module to be unstable when rotated, which makes the user quite inconvenient in adjusting the angle of the display module. In addition, the fixed surface of the case member whose pivot is fixed to the keyboard module often has a floating condition. The fixed surface of the shell member pivotally fixed to the keyboard module may protrude due to the pivotal force. As a result, it not only affects the appearance but also causes damage to the casing.

Moreover, the use of screws not only increases the assembly time, but also requires additional preparation by the manufacturer, which in turn increases the cost of stocking and stocking. Therefore, how to provide an effective reduction of assembly time and cost can reduce the instability of the display module and the keyboard module during rotation, and avoid floating of the fixed surface of the shell member, which is a problem for the relevant industry. One.

The present invention relates to a portable electronic device that fixes a pivot extension by a configuration of a resilient arm to reduce instability of the first module and the second module during rotation, and to avoid the second mode. The first shell of the group has a surface floating phenomenon.

According to the present invention, a portable electronic device includes a first module, a second module, and a pivot. The second module includes a first shell member and a plurality of second shell members disposed on the first shell member. The first shell member includes a body and a snap structure. The engaging structure protrudes from the main body to form an accommodating space. The engaging structure includes a resilient arm that is recessed into the accommodating space toward a concave direction. The pivot shaft includes a first fixing seat and a second fixing seat. The first fixing seat is fixed to one side of one of the first modules. The second fixing base is pivotally connected to the first fixing seat and has an extension piece. The extension member extends into the accommodating space and pushes against the elastic arm in a direction opposite to the concave direction to be fixed in the accommodating space.

In order to provide a better understanding of the above and other aspects of the present invention, the following detailed description of the embodiments and the accompanying drawings

Please refer to FIG. 1 , which is a schematic diagram of a portable electronic device according to an embodiment of the invention. The portable electronic device includes a first module 110, a second module 120, and a pivot 130. In this embodiment, the portable electronic device is used as a notebook computer as an example. Therefore, the first module 110 and the second module 120 are respectively corresponding to the display module and the keyboard module. However, the portable electronic device can also be other forms of devices.

Please refer to FIG. 2A and FIG. 2B , which respectively illustrate schematic views of the second module of the portion in FIG. 1 at different viewing angles. The second module 120 includes a first shell member 121 and a second shell member 122 disposed on the first shell member 121.

Please refer to FIG. 3, which shows a schematic view of the first case member in FIG. 2B. The first case member 121 includes a main body 1211 and an engaging structure 1212. The engaging structure 1212 protrudes from the main body 1211 to form the accommodating space S. The engaging structure 1212 includes a resilient arm 1212a, and the elastic arm 1212a is recessed into the accommodating space S toward the concave direction (that is, the +Z-axis direction).

Please refer to FIG. 4, which shows a schematic diagram of the pivot in FIG. 2B. The pivot 130 includes a first fixing seat 131 and a second fixing seat 132. The first fixing base 131 is fixed to the side of the first module 110 (shown in FIG. 1 ). The second fixing base 132 is pivotally connected to the first fixing base 131 and has an extension piece 132a.

Please refer to FIG. 5, which is a view showing the assembly of the first shell member in FIG. 3 and the pivot shaft in FIG. 4. The extension member 132a extends into the accommodating space S and pushes against the elastic arm 1212a in a direction opposite to the concave direction (that is, the -Z-axis direction) to be fixed in the accommodating space S. As a result, the stability of the first module 110 and the second module 120 during rotation can be improved to increase the convenience of the user when adjusting the angle of the first module 110. In addition, even when the first module 110 is rotated relative to the second module 120, the configuration of the extension member 132a can effectively prevent the fixing surface of the first case member 121 from floating, thereby improving the appearance and reducing the first case. Piece 121 is damaged. Moreover, since the positioning of the extension member 132a does not require the use of a screw, the manufacturer can save the locking time by the screw lock and reduce the preparation for the screw, as compared with the screw locking method. The cost of stocking.

As shown in Fig. 5, the first case member 121 has, for example, two opposite side edges 121s1 and 121s2. The second fixing seat 132 is disposed on the side 121s1 of the first case member 121, and the extension member 132a extends from the side 121s1 of the first case member 121 toward the side 121s2 of the first case member 121. That is, the extension 132a extends toward the +X axis direction.

Please refer to FIGS. 6A-6C , which respectively show cross-sectional views of the extension members in different states of being placed in the accommodating space. The configuration and relationship of each component will be further described below by the assembly process in FIGS. 6A-6C.

In Fig. 6A, the extension member 132a has not been inserted into the accommodating space S. Further, the engaging structure 1212 of the embodiment further includes an upper support portion 1212b and a lower support portion 1212c. The distance d1 between the upper support portion 1212b and the lower support portion 1212c in the concave direction (that is, in the Z-axis direction) is substantially equal to the thickness d2 of the extension member 132a. In addition, the first case member 121 (shown in FIG. 3) further includes a positioning post 1213. The positioning post 1213 protrudes from the body 1211. The positioning post 1213 protrudes from the main body 1211 in a direction opposite to the concave direction (that is, the -Z-axis direction), and the surface 1211s of the main body 1211 protruding from the positioning post 1213 and the lower supporting portion 1212c are used to support the extension 132a. The surface 1212cs is coplanar. In addition, the extension member 132a has a receiving hole 132ah.

As shown in Fig. 6B, the extension member 132a has been placed in the accommodating space S, but the engagement and positioning have not yet been completed. The assembler can apply a force F at the end of the extension 132a to allow the positioning post 1213 to pass through the receiving aperture 132ah. At this time, the front end of the extension member 132a can be placed between the upper support portion 1212b and the lower support portion 1212c, and the intermediate portion of the extension member 132a can be moved in a direction opposite to the concave direction (that is, the -Z-axis direction). Push against the resilient arm 1212a.

As shown in Fig. 6C, the extension 132a has been engaged and positioned. Since the surface 1211s is coplanar with the surface 1212cs, the extension 132a is simultaneously supported by the surface 1211s and the surface 121c2. Furthermore, the extension 132a can be considered to be engaged and positioned by a plurality of sections, as further described below. In the front section area A1, the positioning post 1213 passes through the accommodating hole 132ah and is positioned in the accommodating hole 132ah to restrict the displacement of the extension piece 132a in the XY plane. Further, in the middle section A2, the elastic arm 1212a pushes against the extension 132a in the +Z-axis direction by its own elastic restoring force to restrict the displacement of the extension 132a in the Z-axis direction. Further, in the rear stage region A3, the upper support portion 1212b and the lower support portion 1212c are respectively disposed on opposite surfaces of the extension member 132a. Since the distance d1 of the upper support portion 1212b and the lower support portion 1212c in the concave direction (that is, in the Z-axis direction) (as shown in FIG. 6A) is substantially equal to the thickness d2 of the extension member 132a (as shown in FIG. 6A) Therefore, the upper support portion 1212b and the lower support portion 1212c provide a similarly sandwiched manner to more restrict the displacement of the extension member 132a in the Z-axis direction. In this way, the extension member 132a, which is limited by the plurality of sections, can be stably positioned and engaged.

In addition, the surface 1212s1 of the upper support portion 1212b faces the extension member 132a, and the surface 1212s2 of the elastic arm 1212a faces the extension member 132a, and after the extension member 132a is pushed, the surface 1212s2 of the elastic arm 1212a and the surface of the upper support portion 1212b 1212s1 is substantially coplanar.

The portable electronic device according to the above embodiment of the present invention fixes the extension of the pivot shaft through the configuration of the elastic arm, so as to reduce the instability of the first module and the second module when rotating, and avoid the first The first shell member of the second module has a surface floating phenomenon. Moreover, the pivot of the above embodiment does not require the use of screws for locking, so the manufacturer can save the locking time for screw locking and reduce the cost of preparing and storing the screws.

In conclusion, the present invention has been disclosed in the above embodiments, but it is not intended to limit the present invention.
