Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-2 of the specification, an embodiment of the present invention provides a rotating shaft of a notebook computer with variable rotating torque, which includes a fixing frame 100, a rotating shaft 200 and a sliding sleeve 300.
The fixing frame 100 has a first covering portion 110 disposed along an axial direction thereof and a connecting portion 120 integrally extending outward from an opening wall of the first covering portion 110 in a radial direction, and the connecting portion 120 is connected to a main body portion of the notebook computer.
The outer wall of the shaft body of the rotating shaft 200 is provided with a spiral groove 200a arranged along the axial direction, and the spiral groove 200a is a single-ring spiral groove 200a, the section of the spiral groove is U-shaped, and the processing and the manufacturing are convenient. The second end of the rotation shaft 200 is provided with a mounting portion 200c, and the mounting portion 200c is connected to a screen portion of the notebook computer by a screw.
The sliding sleeve 300 is movably sleeved on the rotating shaft 200, a lock pin 400 is arranged on the sleeve body, and the lower end part of the lock pin 400 is inserted into the spiral groove 200 a. The lock pin 400 has a cylindrical shape, and the edge of the lower end portion thereof is rounded to allow the lock pin 400 to be in good contact with the spiral groove 200a so that the spiral groove 200a presses the lock pin 400.
To facilitate the installation of the lock pin 400, in the present embodiment, a through hole 300c is formed in the body of the sliding sleeve 300, the lock pin 400 is tightly inserted into the through hole 300c, and the lower end portion thereof is inserted into the spiral groove 200a through the through hole 300 c. The axis of the through hole 300c is perpendicular to and intersects with the central axis of the sliding sleeve 300, so as to facilitate the processing of the through hole 300 c.
The outer peripheral wall of the sliding sleeve 300 is provided with a chamfered surface 300a and a flat surface 300b, the chamfered surface 300a gradually gets closer to the central axis of the sliding sleeve 300 along the axial direction of the sliding sleeve 300, and one side of the chamfered surface 300a close to the central axis of the sliding sleeve 300 is butted with the flat surface 300 b. In this embodiment, the chamfered surface 300a extends leftward and the flat surface 300b extends rightward, so that the overall outer peripheral profile of the sliding sleeve 300 is gradually reduced in size from the chamfered surface 300a to the flat surface 300 b.
The first covering portion 110 covers the sliding sleeve 300, and has a planar wall 110a attached to the planar surface 300 b. The chamfered surface 300a of the sliding sleeve 300 is located outside the first wrapping portion 110.
As shown in fig. 3-4, when the screen portion and the main body portion of the notebook computer are in a closed state, the oblique plane 300a of the sliding sleeve 300 is located outside the first covering portion 110, and the portion thereof provided with the flat plane 300b is covered by the first covering portion 110. As shown in fig. 5-6, when the rotating shaft 200 rotates clockwise relative to the fixing frame 100, that is, the screen portion of the notebook computer is opened relative to the host portion, the groove wall of the spiral groove 200a presses the locking pin 400 to drive the sliding sleeve 300 to move toward the first wrapping portion 110, so as to prop open the first wrapping portion 110, and reduce the frictional contact area between the sliding sleeve 300 and the wrapping portion, thereby reducing the frictional force between the sliding sleeve 300 and the wrapping portion, and reducing the force required for rotation; on the contrary, when the rotating shaft 200 rotates counterclockwise relative to the fixing frame 100, i.e. the screen portion of the notebook computer is closed toward the host portion, the rotating shaft 200 drives the oblique cutting plane 300a portion of the sliding sleeve 300 to be drawn out from the first covering portion 110, so that the inner wall of the first covering portion 110 is in better contact with the outer wall of the sliding sleeve 300 to increase the friction therebetween, and the force required for rotating the rotating shaft 200 is increased. Therefore, the effect that the notebook is opened lightly and closed heavily is achieved.
In addition, the sliding sleeve 300 is driven to slide along the axial direction of the rotating shaft 200 in the rotating process, so that the sliding sleeve 300 and the first wrapping part 110 generate axial sliding friction, and the rotating damping feeling of the rotating shaft 200 is improved.
Compare the changeable pivot 200 of current rotatory torsion, the utility model provides a pivot 200 simple structure, the manufacturing of being convenient for is favorable to the popularization and the application of pivot 200.
Alternatively, in the present embodiment, the first end of the rotating shaft 200 has a flange portion 200b, a compression spring 500 is provided between the flange portion 200b and the first covering portion 110, and both ends of the compression spring 500 abut against the flange portion 200b and the first covering portion 110, respectively. When the screen portion of the notebook computer is closed relative to the main body portion, the pressing spring 500 is in a compressed state. When the rotating shaft 200 rotates clockwise relative to the fixed frame 100, i.e. the screen part of the notebook computer is opened relative to the host part, the rotating shaft 200 rotates to drive the sliding sleeve 300 to move right, the spring returns to apply a positive force to the sliding sleeve 300 in the same direction as the moving direction of the sliding sleeve 300, and the force required for driving the rotating shaft 200 to rotate is further reduced, i.e. the force required for opening the notebook computer is reduced; when the rotation shaft 200 rotates to drive the sliding sleeve 300 to move left, the spring is compressed to apply a reverse force to the sliding sleeve 300 opposite to the moving direction of the sliding sleeve 300, and the force required for driving the rotation shaft 200 to rotate, namely the force required for closing the notebook computer is increased. Thereby enhancing the light on and heavy off effect provided by the rotation.
Optionally, the fixing frame 100 further has a second covering portion 130 coaxial with the first covering portion 110, the second covering portion 130 is located on a side of the first covering portion 110 away from the chamfer 300a, an inner wall of the second covering portion is smooth, and a spacing groove 100a is formed between the second covering portion and the first covering portion 110. The second coating portion 130 is provided to prevent the sliding sleeve 300 from contacting and pressing other external parts when moving toward the second end of the rotating shaft 200. The spacer groove 100a between the second coating portion 130 and the first coating portion 110 can facilitate the differential processing of the two.
The above is only the preferred embodiment of the present invention, not used in the present invention, and any slight modifications, equivalent replacements and improvements made by the technical entity of the present invention to the above embodiments should be included in the protection scope of the technical solution of the present invention.
