Referring to FIG. 1 and FIG. 3 , when the sliding mechanism 100 is assembled, the slider 42 is first assembled to the bottom plate 10 , and the main body portion 422 of the slider 42 is inserted into the end portion 122 of the clamping hole 12 of the bottom plate 10 . The slider 42 is then pushed to clamp the bottom plate 10 on both sides of the strip section 124 by the clamping grooves 4222 on both sides of the main body portion 422, so that the slider 42 can be slidably assembled on the bottom plate 10 along the strip section 124.

Then, the intermediate plate 20 is mounted on the bottom plate 10, the clamping sleeve 262 of the clamping assembly 26 of the intermediate plate 20 is aligned with the sleeve 182 of the bottom plate 10, and the shaft 184 is inserted into the clamping sleeve 262 and the sleeve 182, so that One end of the intermediate plate 20 is hinged to the bottom plate 10. Then, the intermediate plate 20 is rotated, and the slider 42 is slid to a corresponding assembly position, so that the protruding portion 424 of the slider 42 passes through the matching hole 22 of the intermediate plate 20, and the body 4242 of the protruding portion 424 passes from the matching hole 22 The body hole portion 222 is pierced, and the side extending edge 4244 of the protruding portion 424 is passed through the auxiliary hole portion 224 of the fitting hole 22. At this time, the flange 2242 of the intermediate plate 20 is received in the receiving hole 19 of the bottom plate 10. Then sliding the slider 42 to one end of the opposite end 122 of the strip section 124 of the locking hole 12, the side extension 4244 of the slider 42 will be pressed against the intermediate plate 20, so that the intermediate plate 20 is clamped at the side edge 4244 Between the bottom plate 10.

The two elastic members 50 are then respectively mounted to the intermediate plate 20, each elastic member The connecting shaft 56 at one end of the 50 is inserted into the first mounting hole 24 of the intermediate plate 20, and the connecting shaft 56 is firstly inserted into the first hole portion 242 having a larger diameter, and then the connecting shaft 56 is pushed to slide the segment having the annular groove 562. The second hole portion 244 is inserted into the second hole portion 244 such that the connecting shaft 56 is clamped to the intermediate plate 20.

Referring to FIG. 4, the top plate 30 is finally assembled to the intermediate plate 20, and the guide rail 36 of the top plate 30 is engaged with the guide groove 282 of the intermediate plate 20; then each elastic member 50 is further assembled by the above-described method of assembling the elastic member 50. One end is respectively fastened into each of the second mounting holes 34 of the top plate 30. After installation, the spring strip 52 is slightly tensioned and its two ends are outwardly resisted. Due to the resistance of the spring strip 52, the connecting shaft 56 can stabilize the card. It is fixed in the second hole portion 244 without slipping out.

Finally, the guiding block 44 is fixed to the slider 42 by the pin 46. The pin 46 passes through the first connecting hole 4224 and the second connecting hole 442 to fix the guiding block 44 to the slider 42. The guiding block 44 is sleeved at one end of the guiding hole 32 of the top plate 30. As such, the assembly of the slider mechanism 100 is completed.

Referring to FIG. 4 and FIG. 5, when the top plate 30 is slid, the top plate 30 is pushed in the direction of the arrow A. Since the intermediate plate 20 is hinged with the bottom plate 10, the intermediate plate 20 and the bottom plate 10 do not slide relative to each other, that is, the top plate 30 will be opposite. The intermediate plate 20 and the bottom plate 10 slide. The top plate 30 simultaneously drives one end of each elastic member 50 to slide, and the spring strip 52 of each elastic member 50 is bent to accumulate elastic potential energy, and the position of the guiding hole 32 on the top plate 30 is correspondingly changed to force the guiding block 44 to slide along the guiding hole 32. The guide block 44 will thus slide along the strip 124 of the clamping aperture 12 of the base plate 10 along with the slider 42. When the top plate 30 is slid to a certain position, the degree of bending of the two elastic members 50 is maximized, and the elastic potential energy is correspondingly maximized. At this time, the inclined surface 4243 of the slider 42 will cooperate with the lifting surface 352 of the top plate 30, and The side edge 4244 of the slider 42 slides into the flange 2242 of the auxiliary hole portion 224 along the fold Edge 2242 slides. When the top plate 30 is further slid over this position, the spring strip 52 of the elastic member 50 is opened, and the elastic potential energy accumulated by the elastic member 50 is released, so that the top plate 30 can automatically slide under the action of the elastic member 50. The slider 42 is further slid, the inclined surface 4243 of the slider 42 contacts the lifting surface 352 of the top plate 30 and the forced lifting surface 352 is lifted, and the side extending edge 4244 slides along the flange 2242, that is, the side extending edge 4244 gradually Sliding into the auxiliary hole portion 224, the side extension edge 4244 gradually releases the position of the intermediate plate 20 relative to the opening angle of the bottom plate 10. Since one end of the intermediate plate 20 is hinged to the bottom plate 10 and the guide grooves 282 of the intermediate plate 20 are engaged with the guide rails 36 of the top plate 30, this will cause the intermediate plate 20, together with the top plate 30, to rotate about the shaft 184 with respect to the bottom plate 10. The intermediate plate 20, along with the top plate 30, is gradually rotated relative to the bottom plate 10, and when the guide block 44 is slid to the other end of the guide hole 32, the intermediate plate 20, together with the top plate 30, is unfolded by an angle θ with respect to the bottom plate 10. At this time, the side edge 4244 of the slider 42 is not completely separated from the flange 2242 of the auxiliary hole portion 224, and still resists the flange 2242. Thus, the side edge 4244 can prevent the intermediate plate 20 and the top plate 30 from opposing each other. The opening angle of the bottom plate 10 is increased, that is, the intermediate plate 20 is prevented from being further opened by the external force by the top plate 30.

In this way, when the top plate 30 of the sliding mechanism 100 is slid relative to the bottom plate 10, the top plate 30 can be rotated relative to the bottom plate 10, so that the top plate 30 is opened at a certain angle with the bottom plate 10 after being opened relative to the bottom plate 10. The process of closing is the same as the process of the above opening process, and the action process is reversed, and will not be described here.

Referring to FIG. 6 , when the slider mechanism 100 is applied to a portable electronic device 200 , the portable electronic device 200 includes an upper housing 210 and a lower housing 220 . The upper casing 210 is fixed to the top plate 30, and the upper casing 210 is provided with a window 212. The lower casing 220 is fixed to the bottom plate 10, and a button panel 214 is disposed in the mounting groove 14 of the bottom plate 10. Therefore, the opening or closing of the upper casing 210 relative to the lower casing 220 is achieved by the sliding mechanism 100, and the upper casing 210 is pushed to slide relative to the lower casing 220 by a certain distance. The upper housing 210 is automatically unfolded relative to the lower housing 220. At the same time, the upper housing 210 is angled relative to the lower housing 220, that is, the window 212 forms an angle with the button panel 214 for the user to view the window 212.

After the sliding of the top plate 30 of the sliding mechanism 100 with respect to the bottom plate 10, the bottom plate 10 is formed at a certain angle with the bottom plate 10, so that the use of the sliding mechanism 100 can be increased. After the sliding mechanism 100 is applied to the electronic device, the button panel 214 of the electronic device and the window 212 can be at a certain angle, which is convenient for the user to observe and achieve an optimal visual effect.
