Description

Technical Field

[0001] This utility model relates to a hinge for a portable electronic mobile terminal, which can be a mobile phone, a laptop computer, etc., and especially a portable electronic mobile terminal using a flexible screen. Background Technology

[0002] In mobile terminals using flexible screens, the flexible screen needs to be opened to a flattened state. To improve the feel, a torque mechanism is incorporated into the hinge to provide rotational resistance. Furthermore, some mobile terminals also require a free-dock function, allowing them to stop rotating and position themselves within a certain angle range. Other mobile terminals using flexible screens also need to provide automatic spring-back to flattening when opened to near flattening and automatic closing when closed to near closing.

[0003] However, when the above functions coexist, such as when some mobile terminals require greater rotational resistance, it will affect the normal implementation of the automatic opening and closing functions. Utility Model Content

[0004] The purpose of this invention is to provide a hinge for a portable electronic mobile terminal that can be configured with greater rotational resistance without affecting the normal operation of the automatic opening and closing functions. To this end, this invention adopts the following technical solution:

[0005] A hinge for a portable electronic mobile terminal includes a left rotating arm and a right rotating arm, a left torque output mechanism and a right torque output mechanism. The left and right torque output mechanisms are located between the shafts of the left and right rotating arms. The left and right rotating arms are connected to the left and right torque output mechanisms respectively via a left gear transmission connection mechanism and a right gear connection structure. The gear connection mechanisms engage within a set rotation angle range and disengage outside the set rotation angle range within the rotation angle travel range of the left and right rotating arms.

[0006] Based on the above technical solutions, the present invention can adopt the following further technical solutions or a combination of these further technical solutions:

[0007] The left and right torque output mechanisms each include a torque output shaft parallel to the axis of the left and right rotating arms, respectively. The torque output shaft is fixedly connected to a torque output gear and is connected to a mechanism that applies rotational resistance. The left and right rotating arms are respectively provided with torque input gears that cooperate with the torque output gears.

[0008] The gear connection mechanism includes a torque input gear and a torque output gear. Within the meshing rotation angle range, the torque input gear and the torque output gear rotate synchronously. Within the non-meshing rotation angle range, the torque input gear and the torque output gear can rotate relative to each other.

[0009] The mechanism for applying rotational resistance to the torque output shaft includes a component with a circular structure, which is fixed and the circular structure clamps the torque output shaft. In the disengaged state, the circular structure of the component with the circular structure keeps the rotation angle of the torque output shaft constant, so as to facilitate smooth re-engagement.

[0010] The components with a rounded structure of the left and right torque output mechanisms are connected together.

[0011] The component with the enclosing structure is a sheet-like component, with enclosing structures on both sides of which respectively enclose the torque output shafts of the left and right torque output mechanisms. The torque output mechanism is provided with multiple sheet-like components.

[0012] The shafts of the left and right rotating arms are connected by a gear synchronous reverse rotation connection mechanism. The gear synchronous reverse rotation connection mechanism includes a first gear, a second gear, a third gear, and a fourth gear that mesh in sequence. The first gear and the fourth gear are fixedly connected to the shafts of the left and right rotating arms, respectively. The shafts of the second and third gears are located between the shafts of the left and right rotating arms.

[0013] The left rotating arm and the right rotating arm are rotating arms that are slidably connected to the connecting frame of the left shell and the connecting frame of the right shell of the portable electronic mobile terminal, respectively, or rotating arms that rotate synchronously with the rotating arm.

[0014] By employing the technical solution of this utility model, it can engage the torque mechanism through gear meshing within the angle range where rotational resistance is required, while disengaging the gears within the angle range where rotational resistance is desired to be as low as possible. This allows for the configuration of greater rotational resistance without affecting the normal operation of the automatic opening and closing functions. Furthermore, the structure of this utility model can utilize the idle space created by setting up a synchronous reverse rotation transmission mechanism for gears, eliminating the need for additional space.

[0018] Referring to the accompanying drawings, the portable electronic mobile terminal hinge of this utility model includes a left rotating arm 1 and a right rotating arm 2, a left torque output mechanism and a right torque output mechanism. The left and right torque output mechanisms are located between the shaft 10 of the left rotating arm 1 and the shaft 20 of the right rotating arm 2. The left rotating arm 1 and the right rotating arm 2 are connected to the left torque output mechanism and the right torque output mechanism respectively through a left gear transmission connection mechanism and a right gear connection structure. The gear connection mechanism engages within a set rotation angle range, and does not engage outside the set rotation angle range within the rotation angle travel range of the left and right rotating arms. The set angle can be determined according to the angle range required for the mobile terminal to have a free docking function, for example, the range of 30° to 150° in this embodiment. In this way, within the set rotation angle range, the left rotating arm 1 and the right rotating arm 2 obtain the rotational resistance output by the left torque output mechanism and the right torque output mechanism, respectively. Outside of this range, the torque of the left torque output mechanism and the right torque output mechanism cannot be transmitted to the left rotating arm 1 and the right rotating arm 2. No matter how much torque they can output, it will not affect the normal realization of the automatic opening and closing functions.

[0019] The left and right torque output mechanisms respectively include torque output shafts 30 and 40 parallel to the shafts 10 and 20 of the left rotating arm 1 and the right rotating arm 2. The torque output shafts 30 and 40 are fixedly connected to torque output gears 31 and 41. The torque output shafts 31 and 41 are connected to a mechanism that applies rotational resistance to them. The left rotating arm 1 is provided with a torque input gear 11 that cooperates with the torque output gear 31. The right rotating arm 2 is provided with a torque input gear 21 that cooperates with the torque output gear 41.

[0020] Within the meshing rotation angle range, the torque input gears 11 and 21 and the torque output gears 31 and 41 rotate synchronously; within the non-meshing rotation angle range, the torque input gears 11 and 21 and the torque output gears 31 and 41 can rotate relative to each other.

[0021] In this embodiment, the mechanism for applying rotational resistance to the torque output shaft includes a component with a rounded structure. This component with the rounded structure is fixed, and the rounded structure clamps the torque output shaft, providing torque as rotational resistance. Another advantage of this structure is that, in the disengaged state, by clamping the torque output shaft through the rounded structure of the component with the rounded structure, and by fixing the component with the rounded structure so that it cannot rotate, the torque output shaft can maintain a constant rotation angle. This allows the torque input gear to smoothly re-engage when it returns to the engagement angle.

[0022] As a simple structural implementation, the components with a circular structure of the left torque output mechanism and the right torque output mechanism are connected together, and in turn, they are able to remain stationary relative to the torque output shaft.

[0023] In this embodiment, the component with the enclosing structure is a sheet component 5, with an enclosing structure 51 that encloses the torque output shaft 30 of the left torque output mechanism and an enclosing structure 52 that encloses the torque output shaft 40 of the right torque output mechanism on both sides. The torque output mechanism is provided with multiple sheet components 5, and the number of sheet components 5 can be adjusted according to the required torque.

[0024] The shafts 10 and 20 of the left rotating arm 1 and the right rotating arm 2 are connected by a gear synchronous reverse rotation connection mechanism, allowing them to rotate synchronously in opposite directions. This gear synchronous reverse rotation connection mechanism includes a first gear 61, a second gear 62, a third gear 63, and a fourth gear 64 that mesh sequentially. The first gear 61 and the fourth gear 64 are fixedly connected to the shafts of the left and right rotating arms, respectively. The shafts 620 and 630 of the second gear 62 and the third gear 63 are located between the shaft 10 of the left rotating arm 1 and the shaft 20 of the right rotating arm 2. Therefore, the gear synchronous reverse rotation connection mechanism originally found in portable electronic mobile terminals requires a certain width of space between the shafts 10 and 20 to accommodate the gears 62 and 63. The left and right torque output mechanisms of this invention fully utilize this width for their placement.

[0025] The left rotating arm 1 and the right rotating arm 2 are rotating arms that are slidably connected to the connecting frame of the left shell and the connecting frame of the right shell of the portable electronic mobile terminal, respectively, or rotating arms that rotate synchronously with the rotating arm. In this embodiment, the portable electronic mobile terminal is a mobile phone, specifically an inward-folding flexible screen mobile phone.
