[Embodiment] The hinge structure of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Referring to FIG. 1 and FIG. 2 , the hinge structure 100 includes a first connecting member 10 , a second connecting member 20 , a pivoting member 30 pivotally connected to the first connecting member 10 and the second connecting member 20 , and is disposed at the second The elastic member 40 between the connecting member 20 and the pivoting member 30 and the limiting latch 50 disposed on the second connecting member 20 and engaged with the pivoting member 30. The first connecting member 10 includes a roll type wrap portion 11 and a connecting portion 13 extending from one side of the wrap portion 11. In this embodiment, the number of the first connecting members 10 is two. An opening 111 is formed in the side wall of the wrapping portion 11, that is, the wrapping portion 11 has a "C" shape in cross section. When assembled, the openings 111 of the two first connecting members 10 are respectively located on opposite sides of the connecting portion 13. The second connecting member 20 has a "T"-shaped structure, and includes a connecting shaft 21 and a pivoting portion 23 of a sleeve structure extending perpendicularly from a middle portion of the connecting shaft 21, the pivoting portion 23 being formed with a cavity 231 and an inner wall 233 A pin hole 235 communicating with the cavity 231 is also formed in the side wall of the splicing portion 23. The pivoting member 30 also has a "T" shape and includes a first pivoting portion 31 pivotally coupled to the first connecting member 10 and a second pivoting portion 33 pivotally coupled to the second connecting member 20. The first pivoting portion 31 is a shaft structure including a first shaft segment 311 and a second shaft segment 313 extending from both ends of the first shaft segment 311. The second shaft segment 313 is outside the 7 201040404 'path smaller than the first shaft The outer diameter of the segment 311 extends into the wrap portion 11 of the first connector 10 and is rotatable relative to the wrap portion 11 of the first connector 10. The second turning portion 33 is also a shaft structure, and includes a limiting shaft portion 331 vertically formed on the side wall of the first shaft portion 311 of the first pivot portion 31, and an outer diameter extending from the end of the limiting shaft portion 331 is slightly smaller. The guiding portion 333 and the limiting portion 335 of the groove structure formed on the limiting shaft segment 331. The portion where the limiting shaft segment 331 is in contact with the guiding portion 333 forms a stepped surface 3311 having a side wall 3313. The limiting portion 335 includes a limiting groove 3351 extending in the circumferential direction of the limiting shaft segment 331 and a positioning groove 3353 extending from a side wall of the limiting groove 3351 extending in a direction perpendicular to the extending direction of the limiting recess 3351. In this embodiment, the limiting groove 3351 extends in the second direction, that is, 270° around the circumference of the second pivoting portion 33 around the "B" axis (as shown in FIG. 4), and the number of the positioning grooves 3353 is one and the limit is limited. The position groove 3351 is divided into two sections of 90° and 180°, and the positioning groove 3353 extends from the side wall of the limiting groove 3351 adjacent to one side of the guiding portion 333 toward the adjacent guiding portion 333. The guide portion 333 of the second pivot portion 33 may have a rod-like structure in which the truncated surface is rectangular, triangular, or the like, and only needs to be guided. In the actual application, a plurality of positioning grooves 3353 can be opened on the second pivoting portion 33 as needed, and the arc of the limiting groove 3351 can also be determined as needed. The elastic member 40 is received in the pivoting portion 23 of the second connecting member 20 and abuts against the bottom wall of the pivoting portion 23 . The elastic member 40 is partially sleeved on the guiding portion of the second pivoting portion 33 of the pivoting member 30 . The 333 is placed on the stepped surface 3311 of the limiting shaft section 331 of the second pivoting portion 33. In this embodiment, the elastic member 40 8 201040404 'is a cylindrical spiral spring, and may of course be a conical spring, a spring piece or the like. The limiting pin 50 is a cylindrical pin which is disposed in the pin hole 235 of the pivoting portion 23 of the second connecting member 20 and can extend into the limiting recess of the second pivoting portion 33 of the pivoting member 30. The groove 3351 is located inside the positioning groove 3353. Of course, the limiting pin 50 can also be replaced by a limiting member such as a protruding post protruding from the inner wall of the pivoting portion 23. Referring to FIG. 2 and FIG. 3 together, when the hinge structure 100 is assembled, the wrapping portion 11 of the first connecting member 10 is first pivotally connected to the second shaft portion 313 of the first pivoting portion 31 of the pivoting member 30. The elastic member 40 is placed in the cavity 231 of the pivoting portion 23 of the second connecting member 20, and the second pivoting portion 33 of the pivoting member 30 is inserted into the cavity of the pivoting portion 23 of the second connecting member 20. 231, and one of the elastic members 40 is sleeved on the guiding portion 333 of the second pivoting portion 33. Pressing the pivoting member 30 to align the limiting recess 3351 or the positioning recess 3353 of the second pivoting portion 33 of the pivoting member 30 with the pin hole 235 of the pivoting portion 23 of the second connecting member 20, The position pin 50 is inserted into the pin hole 235 and protrudes into the limiting groove 3351 or the positioning groove 3353 to stop pressing the pivoting member 30 to complete the assembly of the hinge structure 100. In the hinge structure 100 of the embodiment, when the first pivoting portion 31 of the pivoting member 30 is parallel to the connecting shaft 21 of the second connecting member 20, the limiting latch 50 is just inserted into the second pivoting portion of the pivoting member 30. In the positioning groove 3353 on the 33, the elastic member 40 is in a natural state or is compressed. When the hinge structure 100 is used, the first connecting member 10 can rotate relative to the pivoting member 30 and the second connecting member 20 in a first direction, that is, around the "A" axis; the second connecting member 20 can be opposite to the pivoting member 30 and A connector 10 rotates in a second direction, i.e., about the "B" axis. Since the elastic member 40 is a compression spring, the pivoting member 9 201040404 has a resisting effect. Therefore, when the limiting latch 50 is engaged with the limiting recess 3351, the limiting latch 50 is adjacent to the pivoting portion 23 of the second connecting member 20. The side of the bottom wall of the cavity 231 has a certain abutting force between the side of the limiting groove 3351 and the side wall of the guiding portion 333. When the pivoting member 30 is rotated about the "B" axis with respect to the second connecting member 20, the limit is limited. The positional pin 50 has a certain frictional force with the side wall of the limiting groove 3351, so that the pivoting member 30 and the second connecting member 20 can rotate relative to each other and stop at an arbitrary angle. When the pivoting member 30 is rotated about the "B" axis, when the positioning groove 3353 is rotated to the position corresponding to the limiting pin 50, the elastic restoring force of the elastic member 40 is pushed, and the second pivoting portion 33 of the pivoting member 30 is rotated. Moving away from the elastic member 40, the limiting pin 50 slides into the positioning groove 3353 on the second pivoting portion 33, so that the pivoting member 30 stays at a specific angle with respect to the second connecting member 20 even if the first connecting member 10 is at a certain angle with respect to the second connecting member 20 and has a better self-locking feel when staying at the specific angle. In the above hinge structure 100, when the second connecting member 20 rotates relative to the pivoting member 30 and the first connecting member 10, when the limiting latch 50 slides into or out of the positioning groove 3353, it pivots. The member 30 is moved a certain distance along the axial direction of the limiting shaft segment 331 of the second pivoting portion 33 of the pivoting member 30, so that the two portions of the electronic device hinged by the hinge structure 100 are moved by a certain distance in the direction. When the two parts hinged by the hinge structure 100 are relatively rotated, the height between them is also appropriately adjusted. The hinge structure 100 can achieve the relative rotation of the two parts of the electronic device hinged by the hinge structure 100 to a specific angle by the matching pin 50 and the limiting groove 3351 of the limiting portion 335 and the positioning groove 3353. 201040404 'Go to any angle. The structure is simple, the parts are small, and the cost is low. It can be understood that the guiding portion 333 on the second pivoting portion 33 can also be omitted, and one end of the elastic member 40 can directly abut against the stepped surface 3311 of the limiting shaft segment 331. It can be understood that the limiting pin 50 can be disposed on the second pivoting portion 33 of the pivoting member 30, and a blind hole for receiving the limiting latch 50 can be formed on the second pivoting portion 33 on the bottom wall of the blind hole. A compression spring is disposed between the limiting pin 50 and the positioning groove 3351 and the positioning groove 3353 to open the inner wall 233 of the pivoting portion 23 of the second connecting member 20. When the second pivoting portion 33 is inserted into the pivoting portion 23, the limiting latch 50 is retracted into the pin hole of the second pivoting portion 33 by the abutting force of the inner wall 233 of the cavity 231 of the pivoting portion 23, when When the limiting latch 50 moves with the second pivoting portion 33 to the limiting recess 3351 or the positioning recess 3353 of the pivoting portion 23, the limiting latch 50 protrudes from the pin hole under the action of the elastic member. It extends into the limiting groove 3351 or the positioning groove 3353. It can be understood that the second pivoting portion 33 can also be configured as a sleeve structure, and the pivoting portion 23 of the second connecting member 20 can be disposed as a shaft structure, and the elastic member 40 can be disposed.
