Slide tablet

The present invention relates to a slider tablet computer, and more particularly to a slider tablet computer that couples an antenna with a thimble (Pogo Pin).

With the development of mobile communication technologies, portable electronic devices have become more and more popular in recent years, such as portable computers, mobile phones, tablets, multimedia players, and other portable electronic devices with mixed functions. In order to meet people's needs, portable electronic devices usually have the function of wireless communication. Some cover long-range wireless communication range, for example, mobile phones use 2G, 3G, LTE systems and the 700MHz, 850MHz, 900MHz, 1800MHz, 1900MHz, 2100MHz, 2300MHz and 2500MHz bands used for communication, while others cover short The range of wireless communication, such as Wi-Fi, Bluetooth, and WiMAX systems, uses 2.4 GHz, 3.5 GHz, 5.2 GHz, and 5.8 GHz bands for communication.

However, current portable electronic devices cannot avoid exposing the user to an environment in which electromagnetic waves are transmitted. Therefore, the government has set an upper limit for the body to absorb electromagnetic waves, which is measured by the Specific Absorption Rate (SAR). The so-called electromagnetic wave absorption ratio refers to the ratio of the unit mass to the electromagnetic wave energy absorption in the general electromagnetic radiation environment (the device and the human body are kept within 20 cm), and the unit is "W/kg" (W/kg). Taiwan adopts the standard value of electromagnetic wave absorption ratio in Europe, and the electromagnetic wave absorption ratio is less than 2W/Kg as the standard.

Take the slide tablet as an example, it can be roughly divided into two main parts: one is the base (or base), and the other is the movable top cover (or Hinge Up). In order to comply with the safety standards of electromagnetic wave absorption ratio, the antenna is usually designed in the movable upper cover. The antenna is coupled to a radio frequency module located in the pedestal via a connector and a cable. This type of connection is not only costly, but also has the problem that the cable is easily damaged during the opening process.

The present invention provides a slide tablet computer comprising: a base, comprising: a motherboard; a first ejector pin; a second ejector pin; a radio frequency module disposed on the motherboard and configured to transmit or receive a radio frequency And the plurality of metal wires are disposed on the motherboard, wherein the first thimble and the second ejector are respectively coupled to the radio frequency module via the metal wires; and a movable upper cover, including at least one first The antenna, wherein the first antenna is selectively coupled to the first thimble or the second ejector according to an operating state of the slide tablet.
