Description

Cover anti-lost mechanism

The invention relates to a cover anti-lost mechanism, in particular to a cover anti-lost mechanism applied to a portable electronic device such as a mobile phone.

Portable electronic devices such as mobile phones and personal digital assistants (PDAs) are increasingly used. During use, the battery that provides the energy of the portable electronic device needs to be detached from the electronic device for charging according to energy consumption. Therefore, it is necessary to frequently open the battery cover and disassemble the battery.

When the conventional battery cover is opened, it is generally required to be detached from the electronic device body. At this time, the battery cover is completely separated from the electronic device body and is easily lost.

In view of this, it is necessary to provide a cover anti-lost mechanism.

A cover body anti-lost mechanism includes a body and a cover body, the cover body is mounted on the body, the cover body anti-lost mechanism further includes a connecting member connecting the cover body and the body, the connecting member is slidably disposed In the inner surface of the cover body and the body, the connecting member comprises a connecting portion and a fixed end and a free end respectively connected to the two ends of the connecting portion, and a corresponding limiting member is disposed on the inner surface of the cover body a sliding slot is formed between the limiting mechanism and the cover body. The connecting portion is slidably received in the sliding slot. The fixed end is fixed on an inner surface of the body, and the free end is slidably blocked by the limit. The free end has a "T" shape, and its two sides protrude perpendicularly to the direction in which the connecting portion extends, such that the width of the free end is greater than the width of the sliding groove.

Compared with the prior art, the cover anti-lost mechanism movably connects the cover body and the body through the connecting member, so that the cover body is still integrated with the body after being opened relative to the body, so that the cover body can be effectively prevented from being lost.

1 is a perspective exploded view of a cover body anti-lost mechanism according to a preferred embodiment of the present invention; FIG. 2 is a schematic view of a cover body of a cover body anti-lost mechanism according to a preferred embodiment of the present invention; FIG. 3 is a schematic view of a preferred embodiment of the present invention; A schematic view of the cover of the cover anti-lost mechanism relative to the body.

The invention discloses a cover anti-lost mechanism, which is applied to a portable electronic device such as a mobile phone, and is described below by applying the cover anti-lost mechanism to a mobile phone.

Referring to FIG. 1 , the cover anti-lost mechanism 100 of the preferred embodiment of the present invention includes a body 10 (partially shown), a cover 20 and two connectors 30 . The cover 20 is movably coupled to the body 10 by a connector 30.

Two positioning mechanisms 13 are disposed on the surface of the body 10 , and each positioning mechanism 13 includes two first positioning posts 131 protruding from the surface of the body 10 . The body 10 can be a portable electronic device body, and the body 10 of the embodiment is a mobile phone body.

A second limiting mechanism 23 is disposed on the surface of the cover 20 adjacent to the end of the cover 20 . Each of the limiting mechanisms 23 includes four second positioning posts 231 and a blocking member 233 protruding from the surface of the cover 20 . The four second positioning posts 231 of each limiting mechanism 23 are arranged in an array. The blocking member 233 is a sheet-like body, and includes a convex portion 2331 and two flat portions 2332 respectively connected to opposite ends of the convex portion 2331. Each of the straight portions 2332 is provided with two through holes 2334 corresponding to the two second positioning posts 231. The blocking member 233 can be fixedly fixed (eg, thermally fused) to the cover body 20 through the through hole 2334 to form a sliding slot 235 between the protruding portion 2331 and the cover body 20.

The connecting member 30 is substantially strip-shaped and includes a connecting portion 31 and a fixed end 32 and a free end 34 respectively formed at two ends of the connecting portion 31. The fixing end 32 defines two positioning holes 321 , and the fixing end 32 can be fixed on the body 10 through the positioning hole 321 and the first positioning post 131 . The free end 34 has a substantially "T" shape with its sides projecting perpendicularly to the direction in which the connecting portion 31 extends, and the width of the free end 34 is greater than the width of the chute 235. The connecting member 30 can be made of a soft material as needed, such as a rubber having elasticity, or a plastic material such as a plastic or a metal.

Referring to FIG. 2 , when the connector 30 is installed, the fixed end 32 of the connector 30 is first fixed on the body 10 , and the connecting portion 31 is placed between the second positioning posts 231 of the limiting mechanism 23 of the cover 20 . At this time, the second positioning posts 231 are distributed on both sides of the connecting portion 31 in groups of two; then, the blocking member 233 is fixed on the cover body 20 to form the sliding groove 235, and the connecting portion 31 of the connecting member 30 is formed. It is housed in the sliding slot 235, whereby the connecting member 30 integrally connects the cover 20 and the body 10.

Referring to FIG. 3 , when the cover 20 needs to be closed on the body 10 , the cover 20 is pushed to slide the cover 20 along the connecting portion 31 of the connecting member 30 toward the fixed end 32 until the cover 20 abuts the body 10 . And closed (as shown in Figure 2).

When the cover 20 needs to be opened, the cover 20 is pushed in the opposite direction. Since the width of the free end 34 is larger than the width of the sliding slot 235, the fixed end 32 is blocked by the blocking member 233 when the cover 20 slides a certain distance. .

The cover body anti-lost mechanism 100 movably connects the cover body 20 and the body 10 through the connecting member 30, so that the cover body 20 is still connected to the body 10 after being opened relative to the body 10, so that the cover body 20 can be prevented from being lost.

It can be understood that the connecting member 30 can also be multiple, but at least one. Correspondingly, the positioning mechanism 13 and the limiting unit mechanism 23 can also be adjusted according to the number of the connecting members 30.

It can be understood that the positioning holes 321 can also be only one, and can also be multiple, correspondingly, each positioning The number of the first positioning posts 131 included in the mechanism 13 can also be adjusted according to the number of the positioning holes 321 .

It can be understood that each of the limiting mechanisms 23 can include more than four second positioning posts 231, but at least two. Correspondingly, at least two through holes 2334 are formed in each of the two straight portions 2332 of each blocking member 233.

It can be understood that the fixed end 32 of the connecting member 30 can also be fixed on the body 10 by other means. For example, at least one latch is disposed on the fixed end 32, and a corresponding card slot is defined in the body 10, and the card is inserted through the card. The engagement of the slots secures the fixed end 32 to the body 10.

It can be understood that the blocking member 233 can be fixed on the cover body 10 by other means such as welding. In this case, the corresponding positioning holes 231 on the second positioning post 231 and the blocking member 233 on the cover body 10 can be omitted.
