The first bracket includes a position portion, and the position portion is opposite to the restricting member. One of the position portion and the restricting member defines at least one protrusion, the other defines at least one sliding groove. A length of the protrusion is shorter than the sliding groove along a rotating direction of the restricting member, so the protrusion can accelerate in the sliding groove gradually. At least one of the position portion and the restricting member defines a first slope, the protrusion can decelerate along the slope gradually. The hinge assembly has simple structure and good durability. The present invention further provides an electronic device using the hinge assembly.

Description

Hinge structure and electronic device using the same

The present invention relates to a hinge structure and an electronic device using the hinge structure, and more particularly to a hinge structure having a torsion member and an electronic device using the hinge structure.

Common electronic devices, such as notebook computers, flip-type mobile phones, etc., usually need to connect the cover body and the main body by a hinge structure and realize opening and closing of the cover body and the main body. Since the cover body has a certain weight, in order to facilitate the opening, an auxiliary opening element is often added to the hinge structure.

A hinge structure includes a bracket, a rotating shaft passing through the bracket, a limiting structure sleeved on the rotating shaft, a spring piece, a displacement washer and a rotating washer. The rotating shaft has a non-circular shaft body, and the displacement washer has a non-circular central hole, and the central hole has a larger diameter than the outer diameter of the rotating shaft body. The displacement pad has different shapes of edges, and the displacement pad is radially slid relative to the shaft body by different edges and the outer side of the bracket to change the matching relationship between the displacement pad and the rotating pad, thereby changing the compression degree of the elastic piece. The torque generated by the hinge structure is changed, and the user can easily open the cover. However, such a hinge structure complicates the structure by increasing the displacement pad and the rotating pad to complicate the structure.

In addition, a torsion spring is added to the hinge structure, and the cover body is automatically bounced by the elastic force of the torsion spring, and the angle of opening of the cover body is restricted by the limit structure in the hinge structure. because The rotation speed of the hinge structure will gradually increase under the action of the elastic force. When the limit angle is reached, it will usually stop suddenly. This will cause the hinge structure to be subjected to a large impact force, which will accelerate the wear and the cover body will be more affected. Big vibration.

In view of the above, it is necessary to provide a hinge structure having a simple structure and durability, and an electronic device using the hinge structure.

A hinge structure includes a rotating shaft, a first bracket sleeved on the rotating shaft, a second bracket, a torsion member and a limiting member, and the torsion member is connected with the first bracket and the second bracket to generate the first bracket relative to the second bracket The first bracket has a positioning end that cooperates with the limiting member, and the limiting member is rotatable relative to the positioning end. One of the positioning end and the limiting member is formed with a boss, and the other portion is formed with a receiving protrusion. The sliding groove of the table, and the length of the boss in the rotating direction of the limiting member is smaller than the length of the sliding groove so that the boss can accelerate the sliding in the sliding groove, and the first slope is formed at the end of at least one of the sliding groove and the boss The surface of the first bracket forms a finite wall adjacent to the positioning end, and the sliding slot extends to a periphery of the positioning end, and the limiting wall blocks the peripheral portion of the positioning end a sliding slot is disposed on the limiting member, and the limiting wall cooperates with the limiting end to limit the rotation angle of the limiting member.

An electronic device includes a body, a cover body and a hinge structure for rotatably connecting the cover body to the body, the hinge structure includes a rotating shaft, a first bracket sleeved on the rotating shaft, a second bracket, a torsion member and a limit The torque member is coupled to the first bracket and the second bracket to generate a torque for rotating the first bracket relative to the second bracket. The first bracket has a positioning end that cooperates with the limiting member, and the limiting member is rotatable relative to the positioning end. a boss is formed on one of the positioning end and the limiting member, and a chute for accommodating the boss is formed on the other And the length dimension of the boss in the rotating direction of the limiting member is smaller than the length of the sliding slot so that the boss can accelerate the sliding in the sliding slot, and the end of at least one of the sliding slot and the boss is formed with the first slope to make the convex The speed of the table is gradually reduced, and the first bracket forms a finite wall near the positioning end, and the sliding slot extends to the periphery of the positioning end, and the limiting wall blocks the sliding slot along the peripheral edge of the positioning end, A limiting end is disposed on the limiting member, and the limiting wall cooperates with the limiting end to limit the rotation angle of the limiting member.

The hinge structure is provided with a first slope surface on the first bracket, and the rotation speed of the limiting member can be slowed down during the climbing of the protrusion of the limiting member to prevent the limiting member from suddenly stopping at a faster speed. The impact is created, thereby reducing wear and tear, so that the hinge structure is more durable. In addition, since the first slope surface and the boss are disposed on the original limit unit of the hinge structure, the structure of the hinge structure is also relatively simple.

The first side plate 531 is provided with a non-circular through hole 5311 for accommodating the engaging rod 515 of the rotating shaft 51, so that the second bracket 53 can move with the rotating shaft 51. A second fixing hole 5313 is also formed in the first side plate 531.

A fixing hole 5331 is defined in the second side plate 533 to fix the second bracket 53 to the cover 30 of the electronic device 100.

The limiting member 54 is substantially the same size as the positioning end 521 of the first bracket 52, and is sleeved on the shaft 513 of the rotating shaft 51 against the positioning end 521. The limiting member 54 is provided with a non-circular through hole 541 through which the shaft 513 passes, and a side of the contact with the positioning end 521 is formed with a boss 543 and a second slope 545 at both ends of the boss 543. The edge of the self-limiting member 54 is also bent to form a finite end 547. The size of the boss 543 is smaller than the size of the chute 5213. In the present embodiment, the number of the bosses 543 is two and opposite. The radial length of the boss 543 is substantially the same as the radial length of the sliding groove 5213, but the length in the circumferential direction is smaller than the length of the sliding groove 5213 in the circumferential direction, so when the limiting member 54 rotates relative to the first bracket 52 The boss 543 can slide in the chute 5213. The limiting end 547 can abut against the limiting wall 523 of the first bracket 52 to limit the rotation angle of the limiting member 54.

The torsion member 55 is a torsion spring, and includes a coil portion 551 and a plug end 553 extending from both ends of the coil portion 551. The torsion member 55 is sleeved on the abutting portion 511 of the rotating shaft 51.

Referring to FIG. 1 , FIG. 2 and FIG. 5 , the first bracket 52 is fixedly connected to the main body 10 of the electronic device 100 , and the second bracket 53 is fixedly connected to the cover body 30 , so that the assembled hinge structure 50 will be the main body 10 . And the cover 30 is rotatably connected. The cover body 30 can be fastened to the main body 10 by a fastening device (not shown). At this time, the torsion member 55 is in a compressed state, and the boss 543 of the limiting member 54 falls into the sliding slot 5213 of the first bracket 52. . When the snap-fit is released, the elastic force of the torsion member 55 causes the second bracket 53 to rotate relative to the first bracket 52, thereby causing the cover 30 to be opened. When the rotation starts, due to the elastic force of the torsion member 55, the boss 543 of the limiting member 54 gradually accelerates in the sliding slot 5213; when the second slope 545 of the limiting member 54 and the first slope of the first bracket 52 When the 5215 is in contact, the boss 543 starts to perform the climbing motion, and gradually compresses the elastic piece 56. The resistance of the boss 543 is greater than the torque provided by the torque member 55, so the speed of the limiting member 54 gradually decreases; when the limiting member 54 When the limiting end 547 abuts against the limiting wall 523 of the first bracket 52, the rotation stops.

In the electronic device 100 in the embodiment of the present invention, the torque of the torsion member 55 can automatically open the cover 30. The sliding groove 5213 and the boss 543 are added to the existing limiting unit of the hinge structure 50 to change the spring opening speed of the cover body 30, the structure is simple, and the impact force due to the sudden stop is avoided, and the hinge structure 50 is slowed down. Wear and tear make the hinge structure 50 more durable.

It can be understood that the position of the sliding groove 5213 of the first bracket 52 and the boss 543 of the limiting member 54 can be reversed, or the sliding groove 5213 can be omitted, and only the first slope surface 5215 can be provided, as long as the cover body 30 can be provided. When the relative body 10 is opened, it is accelerated first and then decelerated.

Of course, the first slope surface 5115 may not be disposed on the sliding groove 5213, and only the second slope surface 545 is disposed on the boss 543 to reduce the speed.
