- the front shell assembly is connected to the rear shell by screws and buckles, and then the double-sided adhesive is used to stick the display module to the front shell assembly to shield some unsightly structures, such as screws.
- the above connection scheme has the following drawbacks:
- the embodiment of the present disclosure provides a concealed screw device and a fastening method.
- the technical solution is as follows:
- a stealth screw device installed in a casing for fixedly connecting the casing, the device comprising a driving portion, a screw, a nut and a chip, the driving The portion is fixedly connected to the casing, the driving portion is connected to the screw, the nut is fixedly connected to the other casing of the casing, and the nut is matched with the screw.
- the chip controls the driving portion to operate, and the driving portion drives the screw to move relative to the nut to realize engagement or separation of the screw and the nut.
- the drive unit is a servo motor.
- the casing includes a front casing and a rear casing, the driving portion is fixedly coupled to the front casing, and the nut is fixedly coupled in the rear casing.
- the fixed connection of the drive portion to the housing of the housing is a bonding, screwing or snap connection.
- the fixed connection of the nut to the other casing of the casing is molding implantation, hot pressing or glue Connected.
- a fastening method applied to the stealth screw device operating as follows:
- Step 100 Start the driving part operation by using the chip
- Step 200 The driving portion drives the screw to move, or realize the engagement or separation of the screw with the nut, thereby implementing connection or separation of the casing.
- the fastening method, the step 100 specifically includes the user inputting a correct password through the product control interface, and the driving portion is activated by the chip.
- the drive unit is a servo motor.
- the fixed connection of the drive portion to the housing of the housing is a bonding, screwing or snap connection.
- the fixed connection of the nut to the other housing of the housing is a shaped implant, hot press or glue connection.
- the device and method of the present disclosure adopts a concealed screw structure, which can realize internal link locking, and the appearance does not see any structure; at the same time, it can realize repeated disassembly and assembly without replacing or scrapping any parts; Non-professional dismantling has increased safety.
- FIG. 1 is a structural view of a concealed screw device provided by an embodiment of the present disclosure.
- a stealth screw device As shown in FIG. 1 , a stealth screw device according to an embodiment of the present disclosure is described by taking a mobile phone as an example.
- the stealth screw device is installed in a casing, and the device is used for fixedly connecting the casing. 1 , 4, the device comprises a driving part 2, a screw 3, a nut 5 and a chip (not shown), the driving part 2 is fixedly connected in the casing 1 or 4, the driving The portion 2 is connected to the screw 3, and the nut 5 is fixedly connected to another casing of the casing 4 or 1, and the nut 5 is matched with the screw 3, the chip (not shown) controls the operation of the driving portion 2, and the driving portion 2 drives the screw 3 relative to the nut 5 Movement, achieving engagement or disengagement of the screw 3 with the nut 5.
- the screw 3 can be screwed or unscrewed, and at the same time, can be translated in the axial direction, when the screw 3 and the nut 5 are paired. Engage or separate after the position to achieve the connection or separation of the casing.

- the fixed connection of the nut 5 to the other casing of the casing is a molded implant.
- an embodiment of the present disclosure provides a fastening method applied to the stealth screw device, and the fastening method operates according to the following steps.
- Step 100 The driving unit 2 is activated by the chip
- Step 200 the driving part 2 drives the screw 3 to move, and the meshing or separating of the screw 3 and the nut 5 is realized, thereby achieving connection or separation of the casing.
- the device and method of the present disclosure adopts a concealed screw structure, which can realize internal link locking, and the appearance does not see any structure; at the same time, it can realize repeated disassembly and assembly without replacing or scrapping any parts;
- the method of the present disclosure refers to all the technical solutions of the device, so the method adopts a concealed screw structure, which can realize internal link locking, and the appearance does not see any structure; at the same time, it can realize repeated disassembly without replacing or scrapping any structure. Parts; At the same time, users can specify passwords and other means of confidentiality to prevent non-professionals from disassembling.
- the internal link lock specifically refers to the connection and fixing of the two appearance devices of the front case 1 and the rear case 4, which is realized by the internal structure thereof, and has sufficient strength.
- the step 100 specifically includes: the user inputs a correct password through the product control interface, and activates the driving unit 2 by using the chip.
- the driving unit 2 is a servo motor. Of course, you can also choose other motors.
- the casing includes a front casing 1 and a rear casing 4, the driving portion 2 is fixedly connected to the front casing 1, and the nut 5 is fixedly connected to the rear casing. 4 in.
