Background

Generally, a notebook computer or a foldable electronic product is designed to connect a display screen and a system host respectively by a pivot mechanism, so that the display screen can be rotated to a position covering the system host for being folded or carried about, or rotated to a position extending at a certain angle (e.g. 110 degrees) relative to the system host for being operated.

However, in the above design, the pivot mechanism is a very important component, which has a great influence on the shape of the product, especially on the appearance design. Taking a portable electronic device as an example, two parts of a traditional connecting device rotating around a shaft are respectively fixed on a base and a display screen, and the position of the connecting device relative to the shaft is kept unchanged, so that a product is in a single form.

More importantly, the current trend is for portable electronic devices to be thinner and thinner, and conventional connection devices impose some limitations in this regard. The product form and the appearance design have high requirements on the connecting device. Therefore, a connecting device is required to reduce the restrictions on the product form and design. Fig. 1 is a schematic view showing a state of use of a connecting device in the prior art, and it can be seen that a first body 7 and a second body 8 of a portable electronic device interfere with each other after being rotated to be opened due to a spatial limitation. The air outlet speed is influenced, and the heat dissipation effect is poor.

Referring to fig. 2, a coupling device in a preferred embodiment of the present invention includes a first rotating shaft 1 and a second rotating shaft 2, the first rotating shaft 1 and the second rotating shaft 2 being arranged in parallel by a support member 3; and the rotating member 4 is sleeved on the second rotating shaft 2 and fixedly sleeved on the second rotating shaft 2 along the circumferential direction, and the second rotating shaft 2 moves relative to the first rotating shaft 1 through the rotating member 4. The first rotary shaft 1 is rotatable relative to the second rotary shaft 2 by a support member 3. The rotating member 4 can rotate along with the second rotating shaft 2, and can also rotate independently, and the rotating mode of the rotating member does not limit the protection scope of the present application.

A tongue piece which can rotate along with the second rotating shaft 2 is convexly arranged on one side of the rotating member 4. The tongue has a first end connected to the connecting means and a second end rotatable along the connecting means. The length of tongue piece is greater than the difference in height of user state between first pivot 1 and the second pivot 2, and after the tongue piece rotated down to predetermined angle, the minimum of tongue piece was less than the minimum of first pivot 1.

The coupling device has a supporting state in which the tongue is supported below the second shaft 2. There is also a stowed state in which the tongue is turned over above the second shaft 2.

One end of the supporting member 3 is rotatably sleeved on the first rotating shaft 1, so that the supporting member 3 can rotate relative to the first rotating shaft 1 and generate corresponding torque; the other end of the supporting member 3 is rotatably sleeved on the second rotating shaft 2, so that the supporting member 3 can rotate relative to the second rotating shaft 2 and generate corresponding torque; friction plates may be provided in the backing member 3 to provide appropriate damping.

In each embodiment, the sleeve and shaft may be designed in a similar manner to conventional rotating shafts. For example, friction plates are provided in the sleeve to make the shaft more compact. The description will not be repeated here.

Preferably, the second rotating shaft 2 is sleeved in the second sleeve 32 through the rotating member 4.

And further comprises a first connecting member 5 fixedly connected to the first rotating shaft 1 and a second connecting member 6 fixedly connected to the second rotating shaft 2. Wherein the first connecting member 5 is adapted to be connected with the first body 7 and the first connecting member 5 is adapted to be connected with the second body 8.

Referring to fig. 3 to 7, the embodiment of the invention further discloses a portable electronic device, which includes a first body 7 and a second body 8, wherein the first body 7 and the second body 8 are connected via a connecting device, and the connecting device is pivoted to the first body 7 and the second body 8, so that the first body 7 is rotated to a first position to be stacked on the second body 8, or rotated to a second position to be matched with the second body 8 to form an expansion angle.

In this embodiment, the portable electronic device may preferably be a notebook computer, the first body 7 may preferably be a display, and the second body 8 may preferably be a system host (but is not limited thereto). The system host may have, for example, a keyboard and the display may include, for example, a liquid crystal display. The connection means may comprise any connection means according to the previous and other embodiments. Therefore, the display can horizontally rotate relative to the system host through the connecting device.

The first connecting member 5 is fixed to the second body 8 and is non-rotatably fixed to the first rotating shaft 1. The first coupling member 5 may have a plurality of through holes for coupling the first rotating shaft 1 with screws. Alternatively, the first connecting member 5 may be connected to the first shaft 1 by welding, riveting, splicing, or the like.

The first connecting member is fixed to the second body 8 and rotatably fitted over one end of the first rotating shaft 1 (e.g., by a sleeve) such that the first connecting member 5 can rotate relative to the first rotating shaft 1 and generate a corresponding torque. Thus, the coupling device can utilize the friction force generated by the rotation of the first coupling member 5 to provide sufficient torque on the first rotating shaft 1 (but not limited thereto, meaning that in another embodiment, the present invention can employ other conventional hinge torque designs, such as connecting a torsion spring to the first coupling member 5 and the first rotating shaft 1 to generate torque, and related description is omitted herein) so that the user can rotate the first body 7 relative to the second body 8 to any desired expansion angle.

The second connecting member 6 is fixed to the first body 7 and non-rotatably fixed to the second rotary shaft 2. The second coupling member 6 may have a plurality of through holes for coupling the second rotating shaft 2 with screws. Alternatively, the second connecting member 6 may be connected to the second rotating shaft 2 by welding, riveting, splicing, or the like.

The portable electronic device has a support state in which the rotary member 4 is supported below the second hinge 2. Also has a folding state, wherein the rotating component 4 is turned over to the upper part of the second rotating shaft 2,

the tongue has a first end connected to the connecting means and a second end rotatable along the connecting means. The tongue piece can move to the position of propping against the bottom surface of the base along the arc-shaped guide rail. When the user unfolds the portable electronic device, the user only needs to pull the first body 7 in the direction of the connecting device, and rotate from a first position where the first body 7 is overlapped on the second body 8 to a second position where the first body 7 pivots relative to the second body 8 by an unfolding angle a (e.g., 110 degrees, but not limited thereto).

The second body 8 comprises a base, one end of which extends upwards to form an arc-shaped guide rail. The second end of the tongue may pivot with the first body 7, but in this phase it may not be in contact with the second body 8; when rotated to an angle B (e.g., 70 degrees, but not limited thereto), the second end of the tongue enters the arcuate track. If the first body 7 continues to rotate, the angle between the first body 7 and the second body 8 gradually increases, and the second end of the tongue piece is driven by the connecting device to move along the arc-shaped guide rail until the second end abuts against the bottom surface of the second body 8.

Wherein the arc-shaped guide rail may also be a sliding cavity of a predetermined shape that may be formed on the second body 8. The second end of the tongue may be a sliding body matching the predetermined shape of the sliding cavity.

The second body comprises a fan, and the air outlet direction of the fan faces the first connecting component 5. The length of the tongue piece is greater than the height difference between the first rotating shaft 1 and the second rotating shaft 2 in the use state, and after the tongue piece rotates downwards to a preset angle, the lowest end of the tongue piece is lower than the lowest end of the first rotating shaft 1. Wherein the height from the second rotating shaft 2 to the bottom surface of the second body 8 is less than the height of the tongue piece, so when the lowest end of the tongue piece is abutted against the bottom surface of the second body 8, the tongue piece can lift the height of the second rotating shaft 2, the second rotating shaft 2 drives the first body 7 to be raised, and the distance between the first body 7 and the second body 8 is increased. The air-out of fan can be more smooth and easy, and the radiating effect promotes.

The opening and closing process is essentially symmetrical and is therefore not described further.

It should be understood that although the above description is made of a notebook computer as an example, the connection device in the present disclosure may be applied to other electronic apparatuses such as a mobile phone, a camera, and the like.
