Description of the Invention: [Technical Field] The present invention relates to an electronic device, and more particularly to a notebook computer. [Prior Art] In order to meet the different needs of users for the performance or use of electronic devices, the speed of updating electronic devices on the market is constantly increasing. Due to the different internal configurations of different types of electronic devices, electronic devices often need to be replaced with different external devices or even housings for different internal components. For example, different types of notebook computers usually need to be configured with different circuit boards. The traditional notebook computer connector and data accessor opening are usually installed on the side wall of the notebook computer case. When the different types of circuit boards are replaced, the connector and data accessor interface layout changes. The opening on the notebook case cannot correspond to it, and it is not necessary to replace the notebook case at the same time, resulting in an increase in production cost. * [Summary of the Invention] In view of the above, it is necessary to provide an electronic device that does not need to replace a housing when replacing a circuit board. An electronic device includes a base, the base includes a first housing, at least one mounting portion, and a second housing, the second housing is mounted on the first housing, and the mounting portion is attached The device is disposed between the first housing and the second housing, and the mounting portion is provided with an opening region. Compared with the prior art, the open area of the electronic device of the present invention is disposed in the detachable mounting portion. When replacing the circuit boards of different types, only the corresponding mounting portion needs to be replaced, thereby saving production cost. [Embodiment] Please refer to the first to fourth embodiments, which are preferred embodiments of the electronic device of the present invention. In this embodiment, the electronic device is a notebook computer, and the notebook computer includes a base 1 and an upper cover 2 The base 1 includes a first housing 11, a pair of mounting portions 13, a circuit board 15, and a 6 1308679 second housing 17, wherein the circuit board 15 is a motherboard. The first housing 11 includes a bottom plate 111, a pair of oppositely disposed first side walls 113, and a pair of oppositely disposed second side walls 114. The first side wall 113 and the second side wall n4 extend vertically upward from the edge of the bottom plate 111. Each of the first side walls 113 is provided with a notch 116 and a pair of limiting pieces 118. It is disposed at both ends of each of the first side walls 113 and is bent inwardly to form a receiving space with the corresponding first side wall 113. The bottom plate 111 is respectively provided with a plurality of blocking pieces 121 parallel to the first side walls 113 adjacent to the edges of the first side walls 113. • The bottom plate 111 is provided with a plurality of projections 123 and a plurality of perforations 125 having screw holes. The pair of mounting portions 13 are substantially rectangular plates, and each of the mounting portions 13 has an opening region * 131 protruding outwardly from the notch 116 of the first sidewall 113. The structure of each of the opening regions 131 corresponding to the circuit board 15 Open - multiple connectors and data accessor openings. The circuit board 15 is provided with a plurality of through holes 151 corresponding to the protrusions 123 of the first housing 11 respectively. The inner side of the second housing 17 is provided with a plurality of fixing posts 171 which are provided with screw holes, and the fixing posts 171 respectively correspond to the perforations 125 of the first housing 11. A plurality of elastic pieces 173 are provided at the inner edge of the second casing 17. When assembling, the pair of the first mounting portions 13 are disposed at the two ends of each of the mounting portions 13 and are disposed in the receiving space between the corresponding limiting piece 118 and the first side wall 113. At this time, the opening areas 131 of the pair of mounting portions 13 are respectively received in the notches 116 of the pair of first side walls 113. The blocking pieces 121 assist the limiting pieces 118 to limit the horizontal movement of the corresponding mounting portions 13. . A plurality of screws 18 are inserted through the through holes 151' of the circuit board 15 to the corresponding posts 123 of the first housing 11, so that the circuit board 15 is mounted on the bottom plate hi. The second housing 17 1308679 is fastened to the first housing 11 , and the plurality of screws 19 are inserted through the through holes 125 of the bottom plate 111 to be locked to the corresponding fixing posts 171 of the second housing 17 , thereby The second housing 17 is mounted on the first housing 11 to complete the mounting of the base 1. At this time, the edge of the second casing 17 is pressed against the pair of mounting portions 13, and the vertical movement of the pair of mounting portions 13 is restricted, and the elastic pieces 173 are slightly deformed inward to resist the corresponding mounting portion. 13. Applying an outward force to the pair of mounting portions 13 to limit the horizontal movement of the pair of mounting portions 13, thereby fixing the pair of mounting portions 13 to the first housing 11 and the second housing 17 between. The upper cover 2 is pivotally mounted on the base 1, and the second housing 17 is adjacent to the upper cover 2. As shown in the fourth figure, the installation of the notebook computer is completed. The connector and the data accessor opening of the notebook computer mounting portion 13 correspond to the structure of the circuit board 15. When the circuit board 15 of a different type is replaced, only the pair or the single mounting portion 13 needs to be replaced. However, it is not necessary to replace the first housing 11 or the second housing 17 of the base 1 in order to match the connector and data accessor interface of the circuit board 15. The notebook computer mounting portion 13, the circuit board 15 and the second housing 17 can be mounted to the first housing 11 in a variety of manners, such as a snap hook, etc., and are not limited to the above embodiments. Similarly, the connection of the upper cover 2 to the base 1 can also be achieved in various ways. Of course, the electronic device of the present invention includes not only a notebook computer but also a tablet computer, a video player, a digital assistant, and the like. In summary, the present invention complies with the requirements of the invention patent, and proposes a patent application according to law.
