Embodiment 1

[0026] Such as figure 1 As shown, an invisible screw device provided by the embodiment of the present invention is described by taking a mobile phone as an example in this embodiment. , the device includes a driving part 2, a screw 3, a nut 5 and a chip (not shown in the figure), and the driving part 2 is fixedly connected in the casing-housing (1 or 4), and the driving part 2 is connected with the screw 3, the nut 5 is fixedly connected in the other housing (4 or 1) of the casing, and the nut 5 matches the screw 3, and the chip (not shown in the figure (shown) controls the action of the driving part 2, and the driving part 2 drives the screw 3 to move relative to the nut 5, so as to realize the engagement or separation of the screw 3 and the nut 5.

[0027] Specifically, after the driving part 2 is started, the screw 3 can realize the action of screwing in or out, and at the same time can perform a translational movement along the axis direction. When the screw 3 is aligned ...

Embodiment 2

[0034] see figure 1 , the embodiment of the present invention provides a fastening method applied to the invisible screw device, the fastening method is operated according to the following steps,

[0035] Step 100, start the operation of the driving part 2 through the chip;

[0036] Step 200 , the driving part 2 drives the screw 3 to move, so as to realize the engagement or separation of the screw 3 and the nut 5 , and further realize the connection or separation of the casing.

[0037] The device and method of the present invention adopt invisible screw structure, which can realize internal link locking, and no structure can be seen from the appearance; at the same time, repeated disassembly and assembly can be realized without replacing or scrapping any parts; at the same time, the drive part 2 can be activated through the chip It prevents non-professionals from disassembling the machine and increases safety.

[0038] The method of the present invention refers to all the t...

Abstract

The invention discloses an invisible screw device and a fastening method and belongs to the field of consumer electronics. The device is arranged in a machine shell and used for being fixedly connected with the machine shell. The device comprises a driving portion, a screw, a nut and a chip. The driving portion is fixedly connected in a shell body of the machine shell and connected with the screw, the nut is fixedly connected in the other shell body of the machine shell and matched with the screw, and the chip controls the driving portion to act. The driving portion drives the screw to move relative to the nut, and therefore meshing or disengaging of the screw and the nut is achieved. The invisible screw structure is adopted by the device and in the method, locking and attaching of an internal link can be achieved, and any structure cannot be seen from the appearance. Meanwhile, repeated detaching can be achieved without replacing and scraping any part, by starting the driving portion through the chip, non-professionals can be prevented from detaching a machine, and safety is increased.

Description

technical field [0001] The invention relates to the field of consumer electronics products, in particular to an invisible screw device and a fastening method. Background technique [0002] Consumer electronics products mainly include digital cameras, mobile phones, tablet computers, home office equipment and so on. With the popularization of consumer electronic products, users have more and more stringent demands on the appearance. Users usually hope that the surface of the product is clean, delicate, and seamless, and there are no redundant and useless features. However, screws are the most commonly used fastening method, which is usually observed by users, such as Iphone4, Iphone5, and Samsung S4 after removing the battery cover. The screw structure can be seen, and these visible screw structures will seriously affect the user's desire to buy. [0003] In order to prevent the redundant structure from being seen by the user, fastening methods are usually used to cover it....
