Magnetic magnet clamping structure of notebook computer

The invention relates to a magnet fixing structure of a notebook computer, in particular to a magnet fixing structure suitable for a shell of aluminum-magnesium alloy material, which is convenient to assemble and has a stable fixing effect.

A typical notebook computer is composed of a body and a top cover assembled with a screen, so that the upper cover (screen) can be lifted or closed relative to the body. In the state of the cover, the easily damaged components such as the screen and the keyboard are inside, and the protection can be obtained.

In order to avoid the problem that the upper cover is improperly opened due to the impact of the external force during the carrying process of the user, a closed mechanism is usually provided between the body and the upper cover.

The conventional closing mechanism is composed of a hook, a fastening member, an elastic member and a push button, and the composition is complicated and the operation is inconvenient. Recently, a magnetic structure in which a magnet and a magnetic element are coupled has been adopted as a closing mechanism. The mechanism needs to fix the magnet to the upper position of the screen of the upper cover, and the magnetic element is disposed at a corresponding position in the body, so that when the upper cover is closed, the magnetic cover between the magnet and the magnetic element can be used to close the upper cover and The role of the body.

A common method of fixing the magnet is to adhere the double-sided tape to one side of the magnet, and then attach the magnet to the predetermined position of the casing of the upper cover by the double-sided tape. However, it is easy to cause the problem of falling off due to aging and deterioration of the double-sided tape only by the double-sided adhesive.

Another type of fixing is disclosed in the new patent No. M348452, which is a magnet fixing structure which is formed on the bottom plate to form a second side wall, the first side wall and the third side wall, and the second side wall. An end of the third side wall away from the first side wall is connected by a top wall, and a width between the second side wall and the third side wall is smaller than a width of the magnet, so that when the magnet is placed between the second side wall and the third side wall, The third side wall is elastically deformed to sandwich the magnet together with the second side wall. In this manner, since the elastic force generated by the elastic deformation of the third side wall sandwiches the direction of the magnet and is perpendicular to the direction in which the magnet is placed, there is a problem that the fixing force is insufficient to cause the falling.

Another fixing method is a hot-melt pressing method in which the plastic structure around the magnet is hot-melt-bonded to fix the magnet. Although the fixing method can fix the magnet, the high temperature during the hot melting may cause the Gauss value of the magnet to decrease, and the magnetic induction switch may be malfunctioned after long-term use, and the hot-melt pressing method must be after the magnet is assembled. After a hot melt press process, this will cause a higher manufacturing cost due to the increase in the number of processes.

Therefore, the aforementioned magnet fixing method is still necessary for improvement.

In view of the above, the main object of the present invention is to solve the above problems and to provide a magnet engagement structure which is low in cost, easy to assemble, and has a stable fixing effect.

For the above purpose, the engaging structure of the present invention is used for fixing a magnet having a long rectangular shape to the housing, and the engaging structure is composed of at least two blocks and two elastic arms, and the two blocks are respectively Located at two ends of the first axial direction of the magnet to limit the position of the magnet in the first axial direction, the two elastic arm systems are respectively located on two sides of the first axial direction of the magnet, and the two elastic arms are constrained by the two elastic arms The magnets are disposed at a position of the second axial direction, and each of the elastic arms has a fixed end and a free end, and each of the free ends respectively protrudes from a side of the housing and has a hook protruding from the two hooks. And the housing limits the position of the magnet in the third axial direction.

Therefore, the present invention only needs to apply a force to the magnet into the engaging structure, that is, the second stopper limits the position of the magnet in the first axial direction; and the two elastic arms restrict the magnet in the second axial direction X. The position of the magnet in the third axial direction is restricted by the housing and the two hooks, so that the magnet can be firmly engaged and fixed without falling off.

Preferably, the first axial direction is a long axis direction of the magnet, and the second axial direction is a short axis direction of the magnet, and the third axial direction is a height direction of the magnet.

Preferably, the fixed ends of the elastic arms are formed by the housing extending upwardly, and the fixed ends extend away from one end of the housing to form a free end.

Preferably, the free ends of the elastic arms are horizontally extended from the respective fixed ends, so that each of the elastic arms is inverted L-shaped.

Preferably, the two hooks are away from the one surface of the housing to be a slope, so that the magnets pressing against the inclined surfaces can open the free ends of the elastic arms outward to guide the magnets through the two hooks.

Preferably, each of the blocks is integrally formed by the housing.

Preferably, the engaging structure has three stops, wherein the two blocks are spaced apart at one end of the first axial direction of the magnet, and the other block is located at the other end of the first axial direction of the magnet.

Preferably, the housing protrudes from the magnet integrally with at least one spacer for the magnet to abut against one of the housings.
