Description

The present invention relates to the field of computers and, more particularly, to a computer module of speed control type.

State of the art

Modules of speed control type are currently known. One is described in Chinese Patent Application WO02005CN02204CN.

In the field of computer devices, a portable computer device is widely used in personal computers.

A notebook device often has a display and a host unit that can rotate about each other. Compared to the torque setting of the host computer, the display has a great influence on the use of the computer. In some cases, high torque is required (i.e. tensioned pivot joint). In some cases, high torque is required (i.e., the hinged joint is disassembled). Due to the articulation mechanism, which is successfully installed in the manufacturing process, it is difficult to adjust the torque. Thus, it is difficult to satisfy the torque requirements of the pivot joint in various cases.

The essence of the invention

The object of the present invention is to provide a fast control type computer module which can solve the disadvantages of the existing technology.

In the present invention, a speed control type computer module has a first part and a second part which can rotate relative to a certain angle. The first part comprises the left convexity, the right convexity and the concavity between the left convexity and the right convexity and is intended to accommodate the middle convexity of the second part. The structures of the left convexity and the right convexity are symmetrical, and the three bearing devices with different torques are evenly spaced and mounted on the left convex and right convex respectively. The adjusting motor is located in the middle convexity. Both ends of the adjusting motor are connected to the left-hand thread and the right-hand thread respectively in the opposite direction of rotation. Either the left-hand thread or the right-hand thread are used to control the threaded bearing assembly, which slides axially in the respective bearing assembly in the left convex and right convex. The electronic control unit is mounted on the control motor housing and connected to the control motor. An electronic control unit is used to control the speed of the adjusting motor so that the sliding speed of the threaded bearing unit can be adjusted as required. The left-hand thread extends to the left of the adjusting motor, intersects three bearing devices with different torque in the left convex to the left part of the loop fixedly connected to the left side of the second part, and is held here pivotally. The guide rod is rigidly positioned between the left part of the eyelet and the median convexity, and the guide rod is used to pass through the respective thread bearing assembly to direct movement to the left and right. The right-hand thread extends to the right of the adjusting motor, intersects the three bearing units with different torque in the right convex to the right part of the loop fixedly connected to the right of the second part, and is held here pivotally. The guide rod is rigidly positioned between the right part of the eyelet and the median convexity, and the guide rod is used to pass through the respective thread bearing assembly to direct movement to the left and right. Each bearing unit has an inner ring and an outer ring. The joint insert is located on the inside of the inner ring and is used to connect the friction gears on the circumference of the outer thread bearing unit so that the thread bearing unit and the inner ring of the bearing unit rotate in a fixed manner. When the adjusting motor drives the left-hand thread and the right-hand thread for rotation, the thread bearing assembly in the left-hand and right-hand conveys may move close to each other or move away from one another to selectively connect one of the three bearing units with different torque or left-handed or on the right convex and adjust the torque of the first part relative to the second part.

In the present invention, since two sets of symmetrical pivot connections are formed, the reliability and balance of the connection between the first part and the second part can be ensured. Three bearing units with different torque are arranged in each pivoting joint group. Through interlocking bearing thread blocks with one of three bearing devices with different torque corresponding to the torque can be selected to complete the torque adjustment. The positioning of the guide rod can enhance the mounting properties of the thread bearing assembly and avoid interference in the direction of the circumference of the thread bearing assembly when the first part and the second part rotate relatively, i.e. set the thread bearing unit in the perimeter direction. Through the arranged cylindrical convexity embedded in the second part and the first part of the convexity, additional support can be provided and the reliability of the connection can be enhanced. For example, it can protect the internal moment of the mechanical properties of the adjusting device in the event of external influences. The gear structure is mounted on the circumferential surface of the threaded bearing unit, it can be ensured that the threaded bearing unit and the inner ring of the bearing unit are fixed centrally and can cause the bearing unit to slip along the axial axis of the bearing device for a selected moment. An entire unit with a stable and reliable structure can effectively achieve the torque selection compared to the first part with the second part.

Specific way of realization

The present invention is described in detail in the combination of Figures 1-4.

According to an exemplary embodiment, it has a first part (8) and a second part (9) which can rotate at a relatively certain angle. The first part (8) comprises a left convexity (82), a right convexity (81) and a recess disposed between the left convexity (82) and the right convexity (81) and intended to accommodate the middle convexity (93) of the second part (9). The structures of the left convexity (82) and the right convexity (81) are symmetrical and the three bearing devices (31, 32, 33) with different torques are evenly spaced and mounted in the left convexity (82) and the right convexity (81), respectively. Both ends of the adjusting motor (2) are connected to the left-hand thread (21) and the right-hand thread (210) for rotation respectively; either the left-hand thread (21) or the right-hand thread (210) are used to control the threaded bearing assembly (211) which slides axially in the respective bearing device in the left convex (82) and the right convex (81). The electronic control unit (64) is mounted on the housing of the control motor (2) and connected to the control motor (2). The electronic control unit (64) is used to control the rotational speed of the adjusting motor (2) so that the sliding speed of the thread bearing unit (211) can be adjusted as required. The left-hand thread (21) extends to the left of the adjusting motor (2), intersects three bearing devices (31, 32, 33) with different torque in the left convex (82) to the left part of the loop (92) fixedly connected to the second part (9). ) on the left hand side, and is held here swivel. The guide rod (98) is fixedly disposed between the left loop portion (92) and the center convexity (93), and the guide rod (98) is used to pass through the respective thread bearing assembly (211) to direct movement to the left and right. The right-hand thread (210) extends to the right of the adjusting motor (2), intersects the three bearing devices (31, 32, 33) with different torque in the right convex (81) to the right eyelet (91) fixedly connected to the second part (9). right hand side, and here it swivels. The guide rod is rigidly disposed between the right loop portion (91) and the central convexity (93), and the guide rod is used to pass through the respective thread bearing assembly to direct movement to the left and right. Each bearing device has an inner ring (52) and an outer ring (51). The coupling insert (321) is disposed on the inside of the inner ring (52) and is used to connect the friction teeth (41) on the circumferential surface of the outer thread bearing unit such that the thread bearing unit and the inner ring of the bearing unit rotate. When the adjusting motor (2) drives the left thread and the right thread (210) to rotate, the thread bearing assembly (211) in the left convex (82) and the right convex (81) can move close to each other or move away from each other to selectively connecting one of the three bearing devices (31, 32, 33) with different torque to either the left convex (82) or the right convex (81) and adjusting the torque of the first part (8) with respect to the second part (9).

It is stated that the cylindrical convexities (991, 992) of the bearing, which are pressed into the left convexity (82), are arranged on the left surface and the central convexity (93) of the left loop part (92). The cylindrical convexities of the bearing, which are embossed into the right convexity (81), are arranged on the right surface and the middle convexity (93) of the right eyelet portion (91).

The pinion groove is said to be aligned with the friction pinion (41) located in the coupling insert (321).

The connector insert (321) is said to be of elastic material.

Between the three bearings, the outer bearing has the highest torque, while the inner bearing has the minimum torque.

Because of the two groups of symmetrical pivot joints, the reliability and balance of the first part and the second part can be guaranteed. The three bearing units with different torque are placed in each group of swivel joint. Through a connecting bearing thread block with one of three bearing units with different torque, the corresponding torque can be selected to complete the torque adjustment. The positioning of the guide bar can enhance the mounting properties of the thread bearing unit and avoid interference in the circumferential direction of the thread bearing unit when the first part and the second part rotate relatively, i.e. fixes the thread bearing assembly in the perimeter direction.

Through the arranged cylindrical convexity fixed in the second part and the convexities in the first part, additional assistance in reinforcing the connection can be provided and the reliability of the connection may be enhanced. For example, it can protect the mechanical properties of the internal moment control device in the event of external influences. The gear design is located on the circumferential surface of the threaded bearing unit to ensure that the threaded bearing unit and the inner ring of the bearing unit are rotatably aligned and can cause the threaded bearing unit to slip axially relative to the bearing units to a selected moment.

In accordance with the foregoing, various modifications may be made to the person skilled in the art as defined in the operating mode within the scope of the present invention.
