Support base and electronic device using same

The present invention relates to an electronic device, and more particularly to an electronic device having a detachable support base.

With the continuous advancement and innovation of electronic technology, many electronic products have entered the living environment, bringing people many conveniences in work and life, and providing faster, time-saving and labor-saving efficiency. In order to be portable, to facilitate the use of electronic products, and to increase the efficiency of work, electronic products are gradually becoming more practical, refined, light, thin, short, and small design direction. Computers are the most common and convenient tools used in modern life and work. A desktop computer that is commonly used, including a screen, a host computer, a keyboard, a mouse, a printer, and related peripheral devices, is not available for carrying because of its numerous devices, difficulty in installation, and limited use. Therefore, a notebook computer that can provide the advantages of being portable and convenient to use has an advantage in this respect.

However, most of the notebook computers currently used are foldable and have a screen and an operation interface design. After the notebook is turned on, the screen and the operation interface are placed in a vertical manner (about 90°) for the user to input signals through the operation interface. Although the notebook computer provides the convenience of being able to carry it with you, it still has a certain size in the appearance volume, and the weight is also about 1, 2 kilograms (or more), so it is still slightly not carried when used or used. Convenience. Therefore, a tablet computer (for example, an iPad) that creates a single body device through the touch screen mode generates an operation interface for inputting signals on the touch screen of the tablet computer for direct contact with the user. Control the operation interface to input the operation signal. In this way, a single screen can be used for computer work, and the size of the computer can be greatly reduced. However, the tablet only has a touch screen, which still has some inconvenience and trouble in operation and application. For example, the tablet's touch screen can only be placed horizontally, and cannot be placed sideways or tilted. When using it, you must look down at the screen, which may cause discomfort to the neck and shoulders of the user. If the tablet is leaned against other objects, it is difficult to locate and may cause the tablet to slide and cause inconvenience in operation.

Therefore, with the development of tablet PCs, it has also led to the emergence of peripheral products, especially the physical keyboard products can give users good operation feedback for usability. Take the keyboard accessories of the tablet as an example. In addition to the independent external keyboard, there are some designs that can combine the tablet and the keyboard, such as a holster with a built-in detachable (or non-removable) keyboard. Comes with a hard cover. Even some tablet PCs are original accessories with a dedicated keyboard function, which can be used in conjunction with a general notebook computer.

However, although the combination of the tablet and the keyboard accessories is similar to the operation of the notebook computer, since the external keyboard is different from the general notebook computer, the internal components are required to be small, and the relative weight is also relatively light. After the external keyboard is connected to the tablet, if the opening angle is too large, it will easily cause the whole machine to fall backwards, causing the user's burden. Even if there are many products to add a lot of structure in the support part in order to solve this problem, in addition to the appearance is not beautiful, it also results in the product is not durable and increase the weight.

In order to solve the problems of the prior art, one technical aspect of the present invention is a support base having a rail and a side rack on the bottom plate, and the main rotating mechanism has a standard gear, a first bevel gear, a support frame, The second bevel gear and the structure of the rotating shaft. When the rotating shaft rotates, the two bevel gears are driven to convert the vertical rotating motion into the horizontal rotating motion. The horizontally rotating standard gear is then operated with the side racks to achieve the function of driving the integral rotating mechanism to move forward along the track of the bottom plate.

According to an embodiment of the invention, a support base includes a bottom plate, a rack, a standard gear, a first bevel gear, a support member, a second bevel gear, and a rotating shaft.

The first bevel gear slidably engages the track and is coaxially coupled to the standard gear. The support member is pivotally connected to the axis of the first bevel gear. The second bevel gear meshes with the first bevel gear. The rotating shaft passes through and connects the second bevel gear and pivots the supporting member for rotating the second bevel gear relative to the supporting member, so that the first bevel gear driven by the second bevel gear rotates along with the standard gear relative to the rack and simultaneously along the track mobile.

In one embodiment of the invention, the rack is substantially parallel to the track.

In an embodiment of the invention, the rack is located at an edge of the bottom plate.

Another aspect of the present invention is an electronic device that mainly provides a design in which a panel module (for example, a tablet computer) is matched with a support base including a keyboard module. By means of a mechanism designed to be rotatable and simultaneously moved in the support base, the panel module can be switched between the closed state and the fully expanded state after the panel module and the support base are combined, and the panel module is The projection centered on the support is not offset from the support.
