When the movable assembly 40 is in the first state, the second wheel 42 drives the limiting portion 413 to limit and match with one of the protruding portions 311, so that the engaging portion 411 abuts against the sub-plate 20. When the movable assembly 40 is in the second state, the second wheel 42 drives the position-limiting portion 413 to separate from the boss 311, and the position-limiting portion 413 is located in the sliding slot 312, so that the engaging portion 411 separates from the sub-plate 20.

The first end of the first wheel 41 is provided with an engaging portion 411, and the engaging portion 411 may be a hook extending along the radial direction of the first wheel 41. A boss 412 is provided on the first runner 41 at a position near the second end thereof, the boss 412 is a circular truncated cone protruding along the outer wall surface of the first runner 41, and the boss 412 is spaced apart from the engaging portion 411.

A side of the boss 412 facing the first end of the first wheel 41 is provided with a stopper portion 413, and the stopper portion 413 may extend toward the first end of the first wheel 41. In the present application, the number of the limiting portions 413 on the boss 412 may be two, and the two limiting portions 413 are spaced apart from each other and arranged on the boss 412. Of course, the specific number of the limiting parts 413 may be specifically set according to actual needs, and is not described in detail in this application.

The second roller 42 may be sleeved on the first roller 41, and the second roller 42 is movable in the axial direction of the sleeve 30.

An elastic member 43 is disposed at an end of the first pulley 41 extending into the sleeve 30, a first end of the elastic member 43 may be connected with a second end of the first pulley 41, and a second end of the elastic member 43 is connected with a second end of the sleeve 30. The movement of the second roller 42 in the axial direction of the sleeve 30 is facilitated by providing the resilient member 43 on the first roller 41, and the resilient member 43 can be compressed by the first roller 41 during the movement of the second roller 42. Alternatively, the elastic member 43 may be a spring, a first end of which may be sleeved into the first pulley 41 and abut against the boss 412, and a second end of which is connected with the second end of the sleeve 30.

When the movable assembly 40 is in the first state, the limiting portion 413 on the boss 412 abuts against the lowest portion of the boss 311 in the sleeve 30, the elastic member 43 is in the compressed state, an upward elastic force is provided for the first rotating wheel 41, the limiting portion 413 and the boss 311 are in limiting fit more stably, the engaging portion 411 abuts against the secondary plate 20 at the moment, the positioning of the secondary plate 20 and the main plate upper cover 10 is realized, the elastic sheet 21 around the secondary plate 20 is prevented from being scraped over, and the main plate and the secondary plate 20 are prevented from being raised. When the movable assembly 40 is in the second state, the limiting portion 413 on the boss 412 moves to a position of the sleeve 30 near the first end thereof along the sliding slot 312, the elastic force of the elastic member 43 is reduced, the engaging portion 411 is disengaged from the sub-board 20, and the sub-board 20 is released from the main board cover 10, so that the sub-board 20 is detached.

According to an embodiment of the present invention, the protrusion 311 is a fitting column, a first inclined surface 3111 is formed on a side of the fitting column facing the second end of the sleeve 30, the position-limiting portion 413 is a position-limiting column, a second inclined surface 4131 is formed on a side of the position-limiting column facing the first end of the first pulley 41, the second inclined surface 4131 is in position-limiting fit with the first inclined surface 3111, and a tooth mark 423 engaged with the second inclined surface 4131 is formed on a side of the second pulley 42 facing the position-limiting portion 413.

That is, as shown in fig. 1, 2 and 6, the protrusion 311 may be provided as a fitting column, a side of the fitting column facing the second end of the sleeve 30 is processed as a first inclined surface 3111, the stopper 413 may be provided as a stopper column, and a side of the stopper column facing the first end of the first pulley 41 is processed as a second inclined surface 4131. The second inclined surface 4131 and the first inclined surface 3111 form a mutual engagement fit. A side of the second pulley 42 facing the stopper 413 may be formed with serrations 423 engaging with the second inclined surface 4131. The second runner 42 moves in the axial direction of the first runner 41, the second runner 42 drives the stopper 413 to rotate in the sleeve by engaging with the second inclined surface 4131 of the stopper 413, and when the stopper 413 rotates to be in limit fit with the first inclined surface 3111 of the boss 311, the engaging portion 411 abuts against the sub-plate 20. When the limiting portion 413 rotates to a position between two adjacent protruding portions 311 to define the sliding slot 312, the engaging portion 411 is separated from the sub-board 20, so that the electronic device 100 is assembled and disassembled. Of course, those skilled in the art can understand that the specific inclination directions of the first inclined surface 3111 and the second inclined surface 4131 can be specifically defined according to actual needs, and detailed description thereof is omitted in this application.

In some embodiments of the present invention, the movable assembly 40 further includes a pressing portion 421, the pressing portion 421 is disposed at the first end of the second roller 42, and the pressing portion 421 protrudes out of the outer wall surface of the second roller 42. The pressing portion 421 is a pressing piece that extends in the circumferential direction of the second runner 42, and the circumferential dimension of the pressing piece toward the second runner 42 is smaller than the circumferential dimension of the outer wall surface of the second runner 42.

In other words, referring to fig. 1, 2 and 6, the movable assembly 40 may further include a pressing part 421, and the pressing part 421 is disposed at an end of the second roller 42 facing the engaging part 411. The pressing portion 421 can protrude out of the outer wall surface of the second roller 42, and an operator can press the pressing portion 421 to move the second roller 42 in the axial direction of the sleeve 30 and drive the first roller 41 to make sound deflection along the axis thereof, so as to switch the movable assembly 40 between the first state and the second state. Alternatively, the pressing portion 421 may be substantially configured as a pressing piece, the pressing piece may extend along the circumferential direction of the second runner 42, and a circumferential dimension of the pressing piece facing the second runner 42 may be smaller than a circumferential dimension of the outer wall surface of the second runner 42, and specifically, the pressing piece may cover a position of a half turn of the first end of the second runner 42. Of course, the specific shape and the specific size of the pressing portion 421 can be set according to actual requirements, and it is within the scope of the present application as long as the pressing portion 421 can be pressed to move the second pulley 42 in the axial direction thereof.

According to an embodiment of the present invention, the second end of the second wheel 42 is provided with at least one protrusion 422, and the protrusion 422 is engaged with the position-limiting portion 413 to drive the position-limiting portion 413 to rotate around the axis of the first wheel 41. The thickness of the stopper 413 is greater than the thickness of the second runner 42 and the projection 422.

That is, referring to fig. 1, 2 and 6, the second end of the second roller 42 is provided with at least one protrusion 422, the protrusion 422 may be provided in a plurality of numbers, the protrusion 422 may be matched with the position-limiting portion 413, when the operator presses the pressing portion 421, the protrusion 422 on the second roller 42 moves toward the sleeve 30, and the protrusion 422 may drive the position-limiting portion 413 to rotate around the axis of the first roller 41. The thickness of the position-limiting portion 413 may be greater than the thickness of the second roller 42 and the protrusion 422, so as to ensure that the second roller 42 and the protrusion 422 can be engaged with the position-limiting portion 413.

The principle of the pressing portion 421 for deflecting the first pulley 41 is as follows: the first and

second pulleys

41 and 42 have teeth coupled to each other, wherein the position-limiting portion 413 of the first pulley 41 can be formed as the teeth on the first pulley 41, the position-limiting portion 413 has a second inclined surface 4131, the second pulley 42 and the projection 422 on the second pulley 42 can be formed as the teeth on the second pulley 42, and the second pulley 42 has the teeth 423 engaged with the second inclined surface 4131. Since the teeth on the first and

second wheels

41 and 42 are both beveled. When the operator presses down the pressing portion 421, referring to fig. 10, the pressing force F can be decomposed into a vertical direction (Fy) and a horizontal direction force (Fx), and the horizontal direction force (Fx) can rotate the first pulley 41 along its axis.

When the main board top cover 10 is assembled and positioned with the main board and the sub-board 20, the operator continuously presses the pressing portion 421 on the second runner 42 until the engaging portion 411 on the first runner 41 catches the sub-board 20, thereby realizing the limit fixation of the main board and the sub-board 20. During the process of the operator continuously pressing the pressing portion 421, the first rotating wheel 41 always has an upward force to press it under the influence of the elastic member 43. Initially, the first pulley 41 abuts against the uppermost surface of the boss 311 of the sleeve 30 (the stopper 413 is located in the slide groove 312). The finger presses the second roller 42 downward until the first roller 41 exits the sliding slot 312, and the first roller 41 deflects a certain angle. When the fingers are released, the limiting part 413 of the first rotating wheel 41 is pressed against the lowest inclined surface of the boss 311 in the sleeve 30 (the movable assembly 40 is in the first state), the clamping part 411 is clamped on the secondary plate 20, and the main plate upper cover 10, the main plate and the secondary plate 20 are assembled and positioned.

When the main plate top cover 10 is detached from the main plate and the sub-plate 20, the pressing portion 421 on the second pulley 42 can be pressed again, and the first pulley 41 is deflected continuously until the limiting portion 413 on the first pulley 41 is separated from the protruding portion 311, so that the limiting portion 413 rotates into the sliding slot 312 between two adjacent protruding portions 311 (the movable assembly 40 is in the second state). At this time, the engaging portion 411 is disengaged from the sub-plate 20, and the engaging portion 411 rotates to the position of the clearance sub-plate 20 with the first runner 41, thereby detaching the sub-plate 20. In the process, the first wheel 41 is always pressed with an upward force by the elastic element 43. When the second roller 42 is pressed again by the released finger, the first roller 41 is deflected to a certain angle, and the position-limiting portion 413 of the first roller 41 is just opposite to the sliding slot 312 defined between two adjacent protrusions 311 in the sleeve 30. When the finger is released, the first rotating wheel 41 moves along the sliding slot 312 to the uppermost inclined surface of the sleeve 30 under the elastic force of the elastic element 43, and the engaging portion 411 is disengaged from the sub-plate 20. A slide 312 in the sleeve 30 may limit the distance between the first wheel 41 and the second wheel 42.

According to one embodiment of the present invention, as shown in fig. 1, the sleeve 30 is mainly composed of a first cylinder 31 and a second cylinder 32, and the first cylinder 31 and the second cylinder 32 are coaxially disposed. The sleeve 30 may be an integral part, and the radial dimension of the first cylinder 31 may be smaller than the radial dimension of the second cylinder 32. The boss 311 is provided in the first cylinder 31, and the boss 412 and the elastic member 43 may be provided in the second cylinder 32.

The electronic device 100 may further comprise a cover plate 50, see fig. 1 and 2, the cover plate 50 may be arranged at the second end of the sleeve 30, and the second end of the sleeve 30 may be closed by the cover plate 50. The cover plate 50 may be riveted with the sleeve 30 to fix the cover plate 50 and the sleeve 30. Of course, the specific structure of the cover plate 50 and the connection manner between the cover plate 50 and the sleeve 30 may be specifically set according to actual needs, and details are not described in this application.
