Description

Handheld device and sliding hinge mechanism thereof

The present invention relates to a hand-held device, and more particularly to a hand-held device having a sliding hinge mechanism.

Referring to FIG. 1 , a slide-type mobile phone usually has a body 10 and a slide cover 20 . The body 10 is provided with an input module 30 , and the slide cover 20 is provided with an explicit module 40 . The slider 20 is slidable relative to the body 10 (as indicated by the direction of the arrow in Figure 1).

Generally, the body 10 and the sliding cover 20 are connected to each other through a sliding hinge. When the mobile phone is in a closed state, the body 10 and the sliding cover 20 are overlapped with each other. When the user wants to operate the input module 30, the slider 20 can be slid relative to the body 10 and extended to a slide-out as shown in FIG. 1 to facilitate the user's operation.

It should be specially noted that when the conventional slide type mobile phone repeatedly switches between the closed state and the open state, the metal components inside the sliding hinge mechanism often collide and emit a sharp impact sound, which not only affects The user's comfort during operation may also cause damage to the internal components of the sliding mechanism, resulting in the mobile phone not functioning properly. On the other hand, since the conventional sliding hinge mechanism mostly achieves the function of grounding by contacting with the metal elastic piece, the metal elastic piece itself tends to be elastically fatigued or deformed as the number of times of use increases, which tends to cause poor grounding effect. In addition, the internal electronic components or antennas of the system cannot be effectively prevented from being affected by electromagnetic interference.

One embodiment of the present invention provides a sliding hinge mechanism for connecting a slide cover of a hand-held device and a body, including a hinge carrier, a slider and a first conductive rubber. The hinge bearing member is fixed to the sliding cover and has a guiding groove. The slider is fixed to the body, wherein the slider is received in the guiding groove and can slide along the guiding groove. The first conductive rubber is disposed on the hinge carrier and located at the first end of the guide groove, wherein when the handheld device is in a closed state, the slider and the first conductive rubber are in contact with each other and electrically connected.

In one embodiment, the slider is electrically connected to the body, and the first conductive rubber is electrically connected to the slider.

In an embodiment, the body and the sliding cover are electrically connected by the slider and the first conductive rubber.

In an embodiment, the guiding groove is parallel to a first direction, and the sliding cover is slidable relative to the body in the first direction.

In one embodiment, the sliding hinge mechanism further includes a second conductive rubber disposed on the hinge carrier and located at the second end of the guide slot. When the slider and the body are slidably deployed, the slider and the second conductive rubber are mutually Contact and electrical conduction.

In one embodiment, the body and the slider are electrically connected by the slider and the second conductive rubber.

In one embodiment, the first and second conductive rubbers are located on opposite sides of the hinge carrier.

In an embodiment, the slider has electrical conductivity.

In an embodiment, the slider is made of a metal material.

In one embodiment, the sliding hinge mechanism further includes two first conductive rubbers and another slider, and the hinge carrier further has another guiding groove, wherein the sliders respectively accommodate the inside of the guiding groove and are solid with the body And the first conductive rubber is respectively located at the first end of the guiding groove.

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

Referring to FIG. 2A and FIG. 2B, the handheld device of the embodiment of the present invention is, for example, a slide-type mobile phone or a personal digital assistant (PDA), which mainly includes a slide cover 100 and a body 200. The display module 100 is provided with a display module 110. The main body 200 is provided with an input module 210. When the user wants to operate the handheld device or uses the input module 210, the slide cover 100 can be along the body 200. A first direction D1 is slidably deployed (as shown in FIG. 2B) so that the electronic device can be switched from the closed state (FIG. 2A) to the open state (FIG. 2B).

In this embodiment, the sliding cover 100 and the body 200 are connected to each other through the sliding hinge mechanism 300 shown in FIGS. 3A and 3B. The sliding hinge mechanism 300 includes at least a hinge bearing member 310, a slider 320, and a first The conductive rubber R1 and the second conductive rubber R2, wherein the first and second conductive rubbers R1, R2 are disposed on the hinge carrier 310 and electrically connected to the sliding cover 100, and the hinge carrier 310 and the sliding cover 100 are fixed to each other. The slider 320 is fixed to the body 200 and electrically connected to each other. The ground plane of the handheld device is located in the body 200, so that the grounding effect can be achieved.

When the slider 100 and the body 200 are slidably switched between the closed state and the open state, the slider 320 slides relative to the hinge carrier 310. Continuing to refer to FIGS. 3A and 3B, the upper and lower sides of the hinge carrier 310 of the sliding hinge mechanism 300 are respectively formed with an elongated guide groove S substantially parallel to the first direction D1, wherein the first and second conductive portions are respectively The rubbers R1 and R2 are fixed to both sides of the hinge carrier 310 at positions respectively at the right end (first end) and the left end (second end) of the aforementioned guide groove S.

It should be specially noted that when the hand-held device is in the closed state (as shown in FIG. 2A), the sliding cover 100 and the body 200 are superposed on each other, and the slider 320 and the first conductive rubber at the right end of the guiding slot S at this time. R1 is in contact with each other and is electrically conductive (as shown in Fig. 3A). On the other hand, when the user wants to use the hand-held device to slide the slide cover 100 relative to the body 200 in a first direction D1 (as shown in FIG. 2B), the slider 320 slides along the guide slot S. And moving to a left end D2 (inverse of the first direction D1) to the left end of the guide S (as shown in FIG. 3B), and then in contact with the second conductive rubber R2 and electrically conducting.

The present invention provides the first and second conductive rubbers R1 and R2 at both ends of the guide groove S, in addition to restricting the sliding of the sliding cover 100 and the body 200 between the closed state and the open state, thereby achieving the limit function. The conductive strips 320 can be electrically contacted with the first and second conductive rubbers R1 and R2, respectively, thereby effectively achieving good electrical conduction between the sliding cover 100 and the system grounding surface in the body 200. The electromagnetic signal interferes with the internal electronic components or antenna of the handheld device and causes adverse effects.

It should be understood that the present invention can also provide the first conductive rubber R1 only at the right end of the guide groove S. In other words, the left end of the guide groove S does not need to be provided with the second conductive rubber R2, so that at least the sliding cover 100 and the body 200 are in the closed state. The function of grounding is achieved by electrically contacting the slider 320 and the first conductive rubber R1. For example, the slider 320 may be made of a conductive metal material, wherein when the slider 320 slides along the guiding slot S to the right end (first end) or the left end (second end), The elastic conductive rubber achieves functions such as buffer cushioning and electrical grounding, and thus can effectively improve the conventional shortcomings such as the sliding hinge mechanism being prone to impact sound and poor grounding effect.

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.
