Torque module of double shaft synchronous transmission

The present invention relates to the structural design of a torsion module of a double-rotor synchronous transmission device; in particular, a novel type of the torque module forming a coupling arm, shielding the actuator and the linkage to establish a protection mechanism.

The utility model is equipped with a pivot or a rotating shaft which can be reciprocally rotated by an external force, and is mounted on an electronic object, such as a mobile phone, a notebook computer, a PDA, an e-book, etc., so that the cover or the display screen can be rotated to have an opening and closing function. The department has been a skilled skill. For example, Taiwan Patent No. 97222022 "Rotary Shaft Structure", No. 98207366 "Pivot Structure" and the like provide a typical embodiment.

In order to provide more operating modes and application ranges for display modules (eg, screens) and/or body modules of electronic objects, the prior art has also disclosed a method between a display module and a body module. The double shaft is arranged to enable the display module and/or the body module to generate different operating modes or rotation angles. For example, Taiwan No. 99211350 "Double Pivot Hub", No. 99225737 "Biaxial Axle", US 7512426 B2 "MOBILE COMMUNICATIONS DEVICE WITH SYNCHRONISING HINGE" patent case, etc., provide a feasible embodiment.

One of the problems in the operation, movement and structural design of such double-shaft or pivot assemblies is that the old method discloses a combination of structures using multiple shafts, gears, and chain links, and transmits power to synchronize the rotation of the two shafts. A technical structure that operates an electronic device to open or close. Considering the rotating shaft or its related combination components, the gears and chain structures for transmitting power are designed to be exposed in a light and thin shape, which makes the whole electronic object have a simple and special design aesthetic. The visual appearance of the look.

However, as is known to those skilled in the art, when the user operates the display module to rotate, driving a plurality of gears, the chain drive shaft, and the synchronous rotation of the motor module, because the shaft combines a plurality of gears and chains. The structural relationship of the sheet transmission is complicated; and, in the process of operating the electronic object, the fingering of the exposed gear and the chain structure is easy to enter the above-mentioned transmission structure or being pinched by the inadvertent or negligent; And this situation is not what we expect.

Typically, these references show the use and structural design of the dual hinges or pivots and their associated bonded components. If the redesign considers the structure of the shaft and related components, as well as the above application, making it different from the conventional one, it will change its use type and increase its application range, which is different from the old method. For example, considering the double-rotor or its related combination components, in accordance with the light and thin design requirements of the electronic device and the structural design of the synchronous movement, a torque module is combined to improve the gears and chains of the conventional art to transmit power. The sheet structure is exposed, and may cause unfavorable conditions, which may affect the power transmission; or further, when the transmission device and the torque module are combined in the electronic device, the appearance and decoration visual effect and structure of the simple and aesthetic design are obtained, and the assembly is simple. And so on. None of these topics have been specifically taught or disclosed in the above references.

Therefore, the main purpose of this creation is to provide a torsion module of a double-shaft synchronous transmission device, which provides a visual appearance with a simple and aesthetically pleasing appearance. The utility model comprises an actuator disposed on the first shaft and a coupling disposed on the second shaft; the actuator and the linkage respectively have a driving portion that can be mutually driven, so that the first shaft and the second shaft generate a synchronous rotation type. And the first shaft and the second shaft are combined with a torque module; the two sides of the torque module are provided with a coupling arm. Assuming that the length of the coupling arm to the reference axis is greater than the length of the reference portion of the clutch abutting portion of the actuator to the reference shaft with a (longitudinal) reference axis, so that the position of the coupling arm is higher than the position at which the above-mentioned driving portion is coupled. The coupling arm is shielded from the position of the extension of the driver, and a protection mechanism is provided to prevent the finger of the person from entering the driver to avoid pinching.

According to the torque module of the present dual-shaft synchronous transmission device, the torque module is a combination of a plurality of plate structures; the plate structure has a frictional contact surface, a first hand, a second hand and an intermediate portion. The plate structure and/or the first hand and the second hand define a shaft hole and an opening communicating with the shaft hole, so that the first hand and the second hand have an elastic range of motion to respond to the first axis, the first Two-axis movement. And, the coupling arm is located on both sides of the middle portion.

Referring to Figures 1, 2 and 3, the torque module of the dual-shaft synchronous transmission of the present invention comprises a first axis and a second axis which are parallel to each other; respectively, which are denoted by reference numerals 10 and 20. The first shaft 10 and the second shaft 20 have pivotal regions 11, 21 and fixed regions 12, 22, respectively. The pivoting regions 11, 21 are formed in a rectangular cross-section structure, and the transmission mechanism composed of the actuator 30 and the interlocking device 40 is combined; the pivoting regions 11, 21 are also combined with the torque module 50; the torque module 50 makes the first shaft 10, When the force of the user's operation of the rotation disappears, the second shaft 20 immediately obtains the positioning effect.

In the embodiment taken, the actuator 30 and the actuator 40 are in a sheet structure, and a plurality of actuators 30 and 40 are arranged in combination to constitute the above-described transmission mechanism. The actuator 30 and the linker 40 have main sections 31, 41 of an annular profile and sub-zones 32, 42 connecting the main sections 31, 41, respectively.

Therefore, when the first shaft 10 and the actuator 30 rotate, the actuator 30 drives the linkage 40 to rotate, forcing the coupling 40 and the second shaft 20 to rotate in the direction in which the opposite actuator 30 moves, thereby causing the first shaft 10, The two shafts 20 produce a synchronous rotation pattern.

Referring again to Figures 1, 2 and 3, the sub-region 32 of the actuator 30 and the sub-region 45 of the actuator 40 are in the form of a convex arm structure, and a fixing member 60, 65 can be pivotally connected or combined. The fixing members 60 and 65 are respectively fixed to the display module 91 and the body module 92 of the electronic device 90 (for example, a mobile phone, a computer, etc.), so that the actuator 30 and the first shaft 10, the linker 40 and the second shaft 20 are provided. The user operates the display module 91 or the body module 92 to rotate and rotate; for example, the situation depicted in FIG.

Figures 1, 2 and 3 also depict the torque module 50 as a combination of a plurality of plate structures 55.

For example, every five actuators 30 and 40 are arranged in a group of transmission mechanisms, and a set of torque modules 50 composed of five plate structures 55 are combined.

It can be understood that the surface 56 of each of the slab structures 55 is responsive to the rotation of the first shaft 10, the actuator 30 and the second shaft 20, and the coupling 40 to form a torsion force to the first shaft 10 and the actuator. When the force of the user's operation and the rotation of the second shaft 20 and the interlocking member 40 disappears, the positioning function is obtained.

Referring to FIGS. 3 and 4, when the person operates the display module 91 to move toward the open position, the first shaft 10 and the driving portion 34 of the actuator 30 are driven by the fixing member 60 to drive the linkage driving portion 44, so that the coupling 40, The second shaft 20, the fixture 65 and the body module 92 move in synchronism; for example, the situation depicted in FIG.
