In the present embodiment, the secondary gear 33 is a straight-toothed bevel gear, and may of course be a helical bevel gear. The thickness of the secondary gear 33 is one-half the thickness of the main gear 13. The elastic member 35 is a disc-shaped elastic piece and is disposed at the large-diameter end of the secondary gear 33. Of course, the elastic member 35 may also be a compression spring, and the number may be greater than three, in addition to being disposed at the large-diameter end of the secondary gear 33, The large diameter end of the main gear 13 is shown in the form number A0101. Page 6 of 17 page 0992064696-0 201218924 The elastic member 35 is provided. The first connecting member 50 includes a resisting portion 5A and a fixing portion 53 formed by bending from the edge of the abutting portion 51. A circular pivot hole 511 is defined in the portion of the abutting portion 51 adjacent to the opposite edges, and two non-circular shaft holes 513 are defined between the pivot holes 511. The mortice portion 53 is perpendicular to the abutting portion 51 for connection with a connecting arm (not shown) between the cover and the body of the electronic device. [0017] The first connecting member 70 is an elongated plate member, and a portion of the pivot hole 511 corresponding to the first connecting member also defines a second frame shaft hole 71 corresponding to the rotating shaft hole 513 of the first connecting member G 50. Two rotating shaft holes 73 are formed in the portion, and the rotating shaft hole 73 on the second connecting member 7 is a hole for engaging with the plug portion 313 of the rotating shaft 31. [0018] The reinforcing member 90 includes a pressing portion 91 of a plate-like structure and a tab 93 formed by bending from the edge of the pressing portion 91. The pressing portion 91 has the same structure as the second connecting member 7 The limiting hole 911 and the tab 93 are fixedly connected to the first connecting member 50 by the reinforcing member 9〇. In the present embodiment, the tab 93 is perpendicular to the pressing portion 91 » ' [0019] Q Please refer to 圊 4 again. When assembling, the deformation portion 311 of the two rotating shafts of the transmission assembly 3 is respectively inserted in the first portion. a connecting member 5 抵 abutting portion. The second shaft hole 513 is disposed, and the secondary gear 33 is sleeved on the rotating shaft 31. The deforming shaft segment 1U of the pivot 11 of the assembly is sequentially passed through the first connecting member 5〇.

[0021] When the cover of the electronic device drives the one shaft assembly 10 relative to the other shaft assembly When the 10 is rotated, one of the main gears 13 transmits the torque to the other main gear 13 through the secondary gear 33, and the two main gears 13 rotate in the opposite direction, thereby realizing the linkage opening and closing of the cover of the electronic device and the body, thereby achieving The opening and closing speed is doubled. During the rotation, the elastic member 35 always abuts against the large diameter end of the secondary gear 33, so that the secondary gear 33 meshes tightly with the main gear 13. [0022] In the hinge structure 100, The elastic member 35 applies an elastic abutting force to the secondary gear 33. When a small amount of wear occurs between the secondary gear 33 and the main gear 13, the elastic member 35 pushes the secondary gear 33 to move in the axial direction to make it and the main The gear 13 is always stably engaged to avoid generation between the secondary gear 33 and the main gear 13 The gap, in turn, ensures that the hinge structure 100 has high transmission accuracy and transmission stability. [0023] In the hinge structure 100, the cam follower 17 of the shaft assembly 10 rotates with the pivot 11 relative to the cam 15, during the rotation, the cam The first protrusion 1513 and the second protrusion 1515 of 15 abut against different portions of the cam follower 17, thereby achieving the purpose of changing the axial force between the components of the shaft assembly 10, and 099137088 Form No. A0101 Page 8 / Total 17 pages 0992064696-0 201218924 The hinge structure 1GG can be kept at the mosquito angle in the rotating process towel. The accommodating space formed by the first connecting member 5〇 and the second connecting member 7Q can provide a dustproof function, thereby ensuring normal rotation of the main gear 13 and the transmission assembly 30. It can be understood that the reinforcing member 9 can be omitted, and the engaging portion (8) of the cam 5 can be engaged in the rotating shaft hole 73 of the second connecting member 70. The thread at the end of the U-U can be omitted, and the bolts on the pivot 11 are locked in the direction of the vehicle using the pins extending through the ends thereof.阙 料 , , 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 。 符合 符合 符合 符合 符合 符合 符合 符合 符合 符合 符合 符合 符合 符合 符合 符合 符合 符合 符合 符合 符合 符合 符合 符合 符合 符合 符合 符合 符合 符合 符合 符合 符合 符合 符合Any equivalent modifications or changes made by those who are familiar with the skill of the present invention in accordance with the spirit of this issue shall be covered by the following patent applications.
