Description

Personal digital assistant with improved keyboard structure

【Technical field】

The utility model relates to a personal digital assistant, in particular to a personal digital assistant with an improved keyboard structure.

【Background technique】

3C electronic information products, especially portable electronic devices (portable devices), such as notebook computers, personal digital assistants (PDA, Personal Digital Assistant), mobile phones, etc., have long been known for their influence on human life style and market. The PDA has the function of integrating a notebook computer and a mobile phone, and even has a Global Positioning System (GPS, Global Positioning System) function. However, most PDAs do not have keyboards at present, and most of the existing PDAs use touch panels to input required information with touch pens. But its input speed is relatively slow, especially when it is more inconvenient to use some software, such as translation software, notepad, etc. when it is necessary to input text conveniently.

In order to solve the problem that the PDA is inconvenient to input data and the input speed is relatively slow, the prior art also adopts an external keyboard and a support frame in combination with a PDA, and utilizes an external keyboard to input data. Because the volume of this external keyboard, support frame structure is bigger than PDA, it is inconvenient to carry, so carrying together with PDA can lose the characteristic that PDA is easy to carry, and before the user utilizes keyboard input data, must carry out external keyboard, support frame. And the assembling work of PDA, also lost the characteristic of easy to use like this.

At present, in the PDA products with portable communication function, in order to make the communication more convenient, the input methods can be roughly divided into the following three types:

1. Use some function keys in the original keys to define them to have communication functions. Users of this design must be familiar with the functions and definitions of all communication keys in order to make them play an effective role in use.

2. Using the design of the software combined with the touch screen, the user touches the communication button displayed on the screen with a stylus to communicate. This kind of design is easy to leave fingerprints or traces on the touch screen, which will affect the appearance of the product, and it is easy to scratch or damage the screen due to excessive force when touching, so users must be careful when touching the communication buttons on the screen. Therefore, most users are not accustomed to this input method.

3. Utilize the communication key similar to that of a mobile phone, and the operation is similar to that of a general mobile phone. However, when a large amount of data is to be input, it is necessary to use the touch screen to click on the displayed small keyboard on the screen, or to input by handwriting. Therefore, when a large amount of data is input, it is still not as efficient as traditional keyboard input.

In view of the above shortcomings of the prior art, it is necessary to provide a PDA with a keyboard that is easy to use and has a small volume.

【Content of utility model】

The purpose of the utility model is to provide a personal digital assistant with a keyboard which is convenient and quick to use and has a smaller volume.

In order to achieve the purpose of the utility model, the utility model provides a PDA with an improved keyboard structure, which includes a body with a display screen and an operating part and a keyboard with a plurality of keys, wherein one end of the body is provided with a The keyboard has a bendable connection part, the keyboard is slidably accommodated in the accommodating groove, and can be turned over to the operation part.

Compared with the existing PDA, the PDA with the improved keyboard structure of the utility model is provided with a slidable keyboard in the PDA body, and through a bendable connection part, the keyboard is turned over to the operation part of the body to realize information input, so that both It can be operated conveniently and quickly like a traditional keyboard without increasing the size of the PDA.

【Detailed ways】

Please refer to FIG. 1 and FIG. 2 , the utility model has a PDA with an improved keyboard structure, which includes a body 10 and a keyboard 20 .

The main body 10 is provided with a display screen 101 and an operation part 102, the display screen 101 is a non-touch screen, the operation part 102 is located below the display screen 101, and its occupied area is small, usually provided with a few buttons for controlling The display screen 101 is used for menu selection or selection confirmation. The main body 10 defines an accommodating groove 103 at one end of the operating portion 102 , and the accommodating groove 103 extends to the inside of the main body 10 , and its size is slightly larger than that of the keyboard 20 .

Please also refer to FIG. 3 , the keyboard 20 is a miniature keyboard slidably accommodated in the receiving slot 103 , and has a connecting portion 201 and a plurality of keys 202 . The connecting part 201 is a flexible circuit board, which is electrically connected with the circuit in the main body 10 , and can be bent at 180 degrees so that the keyboard 20 can be turned over to the operating part 102 for operation.

A plurality of keys 202 are arranged on one side of the keyboard 20 . Because the keyboard 20 is a miniature keyboard, the plurality of keys 202 must be quite small and exquisite, which is very unsuitable for manipulation with fingers, so the PDA with improved keyboard structure can replace the fingers with a stylus (stylus) that is necessary for every PDA. The head is used to press a plurality of buttons 202 with a nib, which is convenient for operation. Each button of the plurality of buttons 202 is groove-shaped, that is, the middle is concave, and it is made of soft light-transmitting material.

Compared with the existing PDA, the PDA with an improved keyboard structure of the present invention is provided with a slidable keyboard 20 in the PDA body 10, and the keyboard is turned over to the operation part of the body through a connecting part 201 formed by a flexible circuit board to realize information input , so that it does not increase the size of the PDA and can be operated as conveniently and quickly as a traditional keyboard. In addition, since each of the plurality of keys 202 is in the shape of a groove, the tip of the pen is not easy to slip off, and the tactile feeling is excellent.

It can be understood that, in order to make the keyboard 20 stacked on the operation part 102 more stable after turning over, a locking structure can be provided on the operation part 102 and the keyboard.
