However, the rotating shaft with such a structure is difficult to realize or relatively accurately realize the function of outputting different torques in a segmented manner in the rotating stroke, i.e. different torques are provided at different stages of the rotating stroke, so as to realize different functions and effects.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a pivot of sectional type moment of torsion is provided to can realize the function of the different moments of torsion of segmentation output easily. Therefore, the utility model adopts the following technical scheme:

a sectional torque rotating shaft comprises a shaft and a shaft sleeve, wherein the shaft is provided with a first section and a second section along the axial direction, and the shaft sleeve is also provided with a first section and a second section; the first section of the shaft is matched with the first section of the shaft sleeve to output a first torque when the rotating shaft rotates, and the first torque meets the torque required by free stop of a rotating part connected with the rotating shaft; the second section of the shaft is matched with the second section of the shaft sleeve, a second torque is output at one section of the rotating stroke range of the rotating shaft, and the rotating resistance is increased on the basis of the first torque required by realizing the free stop by superposing the second torque on the basis of the first torque.

Further, a second torque is output during a second half stroke of the rotary shaft from a position corresponding to the closing to a rotational direction corresponding to the full opening.

Further, the first section and the second section of the shaft sleeve both adopt a reed pipe type structure, the inner wall of one section of angle of the second section of the shaft sleeve along the circumferential direction is set to be a plane, and the surface of one section of angle of the second section of the shaft along the circumferential direction is set to interfere with the plane to output a second torque.

Further, a surface of the second section of the shaft angled in the circumferential direction is arranged to not interfere with the plane without outputting the second torque.

Because of the adoption of the technical scheme of the utility model, the utility model discloses simple structure can solve the one hand and open the problem, realizes the light function of opening (easy open) to can realize the function of segmentation output different moments of torsion accurately, in a flexible way, can also two segmentation moments of torsion combine, no idle stroke, feel unanimously, satisfy the designing requirement, bring better experience for mobile terminal's use and feel.

Fig. 2 is a side view of a second section of a sleeve according to an embodiment of the present invention.

Fig. 3 is the demonstration drawing of the rotation process of the present invention, according to the arrow direction, the second section shaft sleeve and the second section shaft sleeve are sequentially engaged with the closed position corresponding to the rotation shaft, without outputting the second torque, and switched to the different rotation angles of outputting the second torque and outputting the second torque.

Detailed Description

Reference is made to the accompanying drawings. The utility model provides a pivot of sectional type moment of torsion, including axle and axle sleeve to be applied to notebook computer for the example, the screen that needs frequent pivoted can be connected to the axle, the base of the host computer of keyboard or connection screen is taken in the axle sleeve joinable.

The shaft has a first section 11 and a second section 12 in the axial direction, and the sleeve also has a first section 21 and a second section 22. The first section 11 of the shaft and the first section of the shaft sleeve 21 are matched with each other to output a first torque when the rotating shaft rotates, the first torque meets the torque required by the free stop of the rotating part connected with the rotating shaft, and when the rotating shaft rotates to a required angle by hand, once the hand is taken off, the first torque can counteract gravity to keep the current rotating angle.

The second section 12 of the shaft and the second section of the shaft sleeve 22 are matched with each other, a second torque is output at one section within the rotating stroke range of the rotating shaft, and the second torque is superposed on the first torque, so that the rotating resistance is increased on the basis of the first torque required by realizing the free stop.

The second torque is output during the second half of the travel of the shaft from the position corresponding to the closed position to the direction corresponding to the fully open rotation. Therefore, before the mobile terminal is opened to a normal use angle, the inconvenience of operation of turning back due to careless separation of hands is avoided, and meanwhile, the moment can be properly reduced, so that the requirement of one-hand operation can be met. Generally, the second torque may be output after being rotated to open the display screen of the mobile terminal to 90 °.

The first section and the second section of the shaft sleeve both adopt a reed pipe type structure, a slit 20 is arranged in the axial direction to enable the first section 21 and the second section 22 of the shaft sleeve to have elasticity in the radial direction, the inner wall of the second section 22 of the shaft sleeve along one angle in the circumferential direction is set to be a plane 3, and the surface 121 of the second section 12 of the shaft along one angle in the circumferential direction is set to interfere with the plane to output a second torque.

The surface 122 of the second section 12 of the shaft angled in the circumferential direction is arranged so as not to interfere with the plane 3 and not to output the second torque.

The shaft is provided with a portion 13 for linking with the mobile terminal, which may be a portion with a screw hole, a portion with a flat position, etc., and the portion may be connected with a screen housing of the mobile terminal. The sleeve is provided with a connection plate 23, which connection plate 23 is used both for linking with the mobile terminal and, in addition, also for connecting the first section 21 and the second section 22 of the sleeve.

The above description is only for the specific embodiment of the present invention, but the structural features of the present invention are not limited thereto, and any person skilled in the art is in the field of the present invention, and all the changes or modifications are covered in the protection scope of the present invention.
