Interlocking module of the hinge

Abstract

A synchronous movement module of a hinge, comprising a fixed seat and two rotating units. The rotating units are pivotally arranged on the fixed seat symmetrically to each other. Each rotating unit includes a gear member located on the relatively inner side with respect to the other rotating unit, a rotating bracket located on the relatively outer side, and a connecting rod member connecting the gear member and the rotating bracket. The gear member of one rotating unit meshes with the gear member of the other rotating unit. The rotating bracket has a frame body, a rotating shaft pivotally arranged on the fixed seat, and a sliding portion parallel to the rotating shaft and closer to the gear member than the rotating shaft. The connecting rod member has a gear portion meshing with the gear member and a chute accommodating the sliding portion. The rotating brackets can rotate synchronously relative to each other in an opening and closing manner, and during the rotation process, the sliding portion slides in the corresponding chute. By connecting the gear member and the rotating bracket through the connecting rod member of each rotating unit, not only can the number of gear parts be reduced to reduce the cumulative tolerance in the backlash, but also the length of the connecting rod member can be adjusted according to the distance between the gear member and the rotating bracket, and the elasticity of the mechanism design is relatively large.

Description

Technical Field

[0001] The present invention relates to a synchronous movement module of a hinge, and particularly to a synchronous movement module of a hinge suitable for supporting a flexible screen. Background Art

[0002] Referring to Figure 1 and Figure 2 a synchronous movement module of a hinge for supporting a flexible screen 91 in the prior art, which includes two rotatable brackets 92 that can be opened and closed relative to each other and a plurality of transmission gears 93 connecting the rotating shafts 921 of the rotatable brackets 92. In order to provide a space for accommodating the bent portion of the flexible screen 91 in the closed state as shown in Figure 2 , the distance between the rotating shafts 921 of the rotatable brackets 92 is relatively far, and a relatively large number of transmission gears 93 must be arranged between the rotating shafts 921 of the rotatable brackets 92 so that the rotatable brackets 92 can rotate relative to each other synchronously.

[0003] However, the large number of the transmission gears 93 will generate backlash, and the cumulative tolerance in the backlash will cause poor synchronous movement of the rotatable brackets 92. Summary of the Invention

[0004] An object of the present invention is to provide a synchronous movement module of a hinge that can reduce the cumulative tolerance in the backlash.

[0005] In some embodiments, the synchronous movement module of the hinge of the present invention includes a fixed seat and two rotating units. The rotating units are pivotally provided on the fixed seat symmetrically to each other. Each rotating unit includes a gear member located relatively inside with respect to the other rotating unit, a rotating bracket located relatively outside, and a connecting rod member connecting the gear member and the rotating bracket. The gear member is pivotally provided on the fixed seat and meshes with the gear member of the other rotating unit. The rotating bracket has a frame body, a rotating shaft connecting the frame body and pivotally provided on the fixed seat, and a sliding portion connecting the frame body and parallel to the rotating shaft and closer to the gear member than the rotating shaft. The connecting rod member is pivotally provided on the fixed seat and has a gear portion meshing with the gear member and a sliding groove accommodating the sliding portion and allowing the sliding portion to slide therein. The rotating brackets of the rotating units can rotate relative to each other synchronously through the gear members and the connecting rod members, and the sliding portion slides in the corresponding sliding groove during the rotation process.

[0006] In some embodiments, the connecting rod member further has a rod body extending axially and formed with the gear portion, and an extension portion extending from the rod body and formed with the sliding groove.

[0007] In some embodiments, the frame body has an avoidance groove adjacent to the sliding portion for the extension portion to extend into.

[0008] In some embodiments, the fixed seat includes two support members spaced apart from each other, and the rotating unit is located between the support members.

[0009] In some embodiments, the chute extends vertically along the axis of the link member and is elongated.

[0010] The present invention has the following effects: By connecting the gear member and the rotating bracket through the link members of the respective rotating units, not only can the number of gear parts be reduced to reduce the cumulative tolerance in the backlash, but also the length of the link member can be adjusted according to the distance between the gear member and the rotating bracket, and the mechanism design has greater flexibility.

[0020] Referring to Figures 3 to 6 , an embodiment of the synchronous movement module 100 of the hinge of the present invention includes a fixed seat 1 and two rotating units 2.

[0021] In this embodiment, the fixed seat 1 includes two support members 11 spaced apart from each other. The rotating units 2 are pivotally provided on the fixed seat 1 symmetrically to each other and are located between the support members 11.

[0022] Each of the rotating units 2 includes a gear member 3 located on the relatively inner side with respect to the other rotating unit 2, a rotating bracket 4 located on the relatively outer side, and a connecting rod member 5 connecting the gear member 3 and the rotating bracket 4.

[0023] The gear member 3 is pivotally provided on the fixed seat 1 and meshes with the gear member 3 of the other rotating unit 2.

[0024] The rotating bracket 4 has a frame body 41, a rotating shaft 42 connecting the frame body 41 and pivotally provided on the fixed seat 1, and a sliding portion 43 connecting the frame body 41 and parallel to the rotating shaft 42 and closer to the gear member 3 than the rotating shaft 42. The frame body 41 has an avoidance groove 44 adjacent to the sliding portion 43. In this embodiment, the sliding portion 43 is cylindrical and is separately manufactured and then assembled with the frame body 41. However, in a variant embodiment, the sliding portion 43 can also be integrally formed with the frame body 41. Moreover, the sliding portion 43 is not limited to being connected to the frame body 41 at both ends, and it can also be connected to the frame body 41 at only one end while the other end is an open end.

[0025] The connecting rod member 5 is pivotally provided on the fixed seat 1 and has a rod body 51 extending along the axial direction, an extension portion 52 extending from the rod body 51, a gear portion 53 formed on the rod body 51 and meshing with the gear member 3, and a chute 54 accommodating the sliding portion 43 and allowing the sliding portion 43 to slide therein. The chute 54 is formed in the extension portion 52 and extends in a long shape perpendicular to the axis of the connecting rod member 5. The extension portion 52 extends into the avoidance groove 44. In this embodiment, the chute 54 is closed, but in a variant embodiment, one end of the chute 54 can also be open, that is, generally in the shape of a U-shaped groove.

[0026] Refer to Figure 4 、 Figure 6 、 Figure 7 and Figure 8 , the rotating brackets 4 of the rotating units 2 can synchronously rotate relatively in an opening and closing manner through the gear members 3 and the connecting rod members 5. As Figure 4 and Figure 6 show, the rotating bracket 4 is in a deployed state relatively. As Figure 7 and Figure 8The figure shows that the rotary bracket 4 is in a retracted state. During rotation, the sliding part 43 slides in the corresponding sliding groove 54. In this embodiment, during the process of transitioning from the deployed state to the retracted state, the sliding part 43 moves from the relatively outer end to the relatively inner end of the sliding groove 54, and then moves from the relatively inner end to the relatively outer end. When the rotary bracket 4 rotates approximately 45 degrees, the sliding part 43 moves approximately to the relatively inner end of the sliding groove 54.

[0027] Among the components of each rotation unit 2, only the gear part 53 of the link member 5 and the gear member 3 need to be engaged, which can greatly reduce the cumulative tolerance in the backlash to ensure that the rotary bracket 4 can move synchronously. In addition, the length of the link member 5 can be adjusted according to the distance between the gear member 3 and the rotary bracket 4, and the mechanism design has greater flexibility.

[0028] In summary, by connecting the gear member 3 and the rotary bracket 4 through the link member 5 of each rotation unit 2, not only can the number of gear parts be reduced to reduce the cumulative tolerance in the backlash, but also the length of the link member 5 can be adjusted according to the distance between the gear member 3 and the rotary bracket 4, and the mechanism design has greater flexibility.

[0029] The above are only the embodiments of the present invention, and the scope of implementation of the present invention cannot be limited thereby. That is, all simple equivalent changes and modifications made according to the claims and the content of the specification of the present invention still fall within the scope of the present invention.
