Referring to Figures 1 to 8, the hinge device of the present invention is used to be installed between the upper cover 91 and the base 92 of an electronic product 90, so that the two can be opened and closed relative to each other. The hinge device includes a pivot shaft 10 , a group of connecting seats 20, a fixed seat 30, a positioning block group 40, a pressing assembly 50, an elastic element group 60, multiple friction pads 70 and a fixing piece 80, wherein:

As shown in FIG. 2 , the two ends of the pivot shaft 10 are axially extended to form a positioning rod 11 and a set of connecting rods 12 with a non-circular cross-section, and a limiting block 13 is radially extended on the pivot shaft 10 . Threads are formed near the periphery of the end of the socket rod 12;

The connecting seat 20 is sleeved and fixed on the positioning rod 11 of the pivot 10, which is used to be fixedly integrated with the upper cover 91 of the electronic product 90 so that the two can move together;

The fixed base 30 is used to be fixed on the base 92 of the electronic product 90, which is a pivotable socket rod 12 that is sleeved on the pivot 10, and is located on one side of the pivot 10 forming a limit block 13. A stopper 31 that can resist each other with the stopper 13 protrudes from the side of the seat 30 opposite to the stopper 13 of the pivot 10, so that when the assembly seat 20 and the pivot 10 are relatively fixed to the seat, When the 30 pivots, the relative pivoting angle can be limited by the two limit blocks 13 and 31, and a positioning hole 32 adjacent to the limit block 31 is formed through the fixed seat 30;

The positioning block group 40 is sleeved on the socket rod 12 of the pivot shaft 10 and is located on the other side of the fixed seat 30 forming the limiting block 31. It includes a static positioning block 41 and a dynamic positioning block 42. The static positioning block 41 A stud 411 protrudes from the side opposite to the fixed seat 30. The stud 411 can be inserted into the positioning hole 32 of the fixed seat 30 to fix the relative position between the static positioning block 41 and the fixed seat 30. The moving positioning block 42 is non-pivotably sleeved on the socket rod 12 of the pivot shaft 10, and the opposite surfaces of the two positioning blocks 41, 42 are respectively formed with a plurality of positioning concave and convex parts that can be positioned relative to each other. So that when the pivot 10 drives the moving positioning block 42 to pivot relative to the fixed seat 30 and the static positioning block 41, the positioning concave and convex parts can be positioned at a specific angular position;

Referring further to Figures 3 and 4, the compression assembly 50 is sleeved on the socket rod 12 of the pivot shaft 10, and includes a static compression block 51 and a dynamic compression block 52, the static compression block 51 and the fixed seat 30 are fixed to each other The dynamic pressing block 52 is non-pivotably sleeved on the socket rod 12 of the pivot shaft 10, and the two pressing blocks 51, 52 cooperate with each other on their opposite end surfaces to protrude and form more than one inclined block 511. , 521, one end of the inclined block 511, 521 protrudes relative to the end face of the compression block 51, 52 to form a stage surface 512, 522, and the other end is flush with the end face of the compression block 51, 52 and adjacent to The bottom edges of the step surfaces 512, 522 of the inclined blocks 511, 521 meet, so that an arc-shaped inclined surface is formed between the two ends of the inclined blocks 511, 521. There are flat surfaces 513, 523 parallel to the end surfaces of the compression blocks 51, 52;

The elastic element group 60 is sleeved on the socket rod 12 of the pivot shaft 10, and is located between the positioning block group 40 and the pressing assembly 50, and includes a plurality of adjacent elastic pieces with an arc-shaped section;

The friction pad 70 is sheathed on the socket rod 12 of the pivot 10, and is respectively located on both sides of the positioning block set 40 and the pressing assembly 50;

The fixing part 80 is sleeved and fixed on the end of the sleeve rod 12 of the pivot shaft 10, so that the aforementioned elements sleeved on the sleeve rod 12 are tightly against each other, and the fixing part 80 is formed with an internal screw hole for screwing. It is fixed on the thread of the socket rod 12.

5 and 6, when the upper cover 91 is gradually closed relative to the base 92, the flat surface 523 of an inclined block 521 of the dynamic compression block 52 will gradually move along its inclined surface to an inclined block of the static compression block 51. The flat surfaces 513 of 511 are opposite, at this time, because the flat surfaces 513, 523 are the thicker positions on the two compression blocks 51, 52 respectively, so the elastic element groups 60 that are positioned on the side will be pushed away, so that the elastic pieces are connected to each other. Closely abut against each other, resulting in increased friction, which means that the user must gradually increase the force applied to the upper cover 91, so that the upper cover 91 and the base 92 can be relatively closed, so that the two can be effectively avoided due to excessive closing speed. hit.

As shown in Figures 6 and 7, when the upper cover 91 is gradually opened relative to the base 92, the stage surface 522 of the inclined block 521 of the dynamic compression block 52 will gradually move to the stage of another inclined block 511 of the static compression block 51. The faces 512 are facing each other. At this time, because the two compression blocks 51, 52 are relatively thinner parts with their thicker parts respectively, so although the elastic element group 60 located on the side will also be pushed away, their respective elastic Due to the reduction of external force between the plates, the friction force is not as large as when the upper cover 91 and the base 92 are relatively closed, and the user can achieve the purpose of quick opening in a relatively labor-saving manner. In addition, when the inclined blocks 511 on the two pressing blocks 51, 52, When the stage surfaces 513 and 523 of the 521 abut against each other, they can also achieve the function of limiting, limiting the angle range that the upper cover 91 can open.
