A roller module includes a wheel disc, a magnetic conductor and an electro-permanent magnet assembly. The wheel disc is rotatable along a rotation axis line. The magnetic conductor is coaxially arranged and synchronously rotated with the wheel disc. The magnetic conductor includes a hub and plural spokes. The plural spokes are radially extended from the hub. The magnetic conductor is arranged between the wheel disc and the electro-permanent magnet assembly. When the electro-permanent magnet assembly is operated in the first operating status, the electro-permanent magnet assembly provides a first magnetic attraction force to at least one spoke in the axial direction. When the electro-permanent magnet assembly is operated in the second operating status, the electro-permanent magnet assembly provides a second magnetic attraction force to at least one spoke in the axial direction. The first magnetic attraction force is greater than the second magnetic attraction force.

A mechanical keyboard is provided, which includes a plurality of mechanical keys, a circuit board, a plurality of first magnetic elements, a lower casing and a plurality of second magnetic elements. The mechanical keyboard has a key region and an edge region surrounding the key region. The mechanical keys are located in the key region. The circuit board is disposed beneath the mechanical keys. The first magnetic elements are disposed beneath the circuit board and distributed in the key region. The lower casing is disposed beneath the mechanical keys, the circuit board and the first magnetic elements. The second magnetic elements are disposed over the lower casing, in which the second magnetic elements respectively correspond to the first magnetic elements and respectively repel the first magnetic elements.

Mechanical keyboard

A roller module includes a scroll wheel, a magnetization member, a swinging element and a pole-reversible magnetic element. The magnetization member is synchronously rotated with the scroll wheel. The swinging element includes a pivotal part, a first magnetic element and a second magnetic element. The first magnetic element and the second magnetic element are movable by using the pivotal part as a rotation center. The pole-reversible magnetic element and the first magnetic element interact with each other. Consequently, the second magnetic element is close to or away from the magnetization member.

Roller module and input device with same

A roller module for a mouse includes a roller, a ratchet assembly and a counterweight assembly. The ratchet assembly and the counterweight assembly are installed in the roller. When the roller is rotated at a slow speed, the magnet blocks in the counterweight assembly and the magnetic ratchet are magnetically attracted by each other. Consequently, a stepped rotation feel is provided. When the roller is rotated at a fast speed, the magnet blocks are moved with the corresponding counterweight blocks in the counterweight assembly and gradually moved away from the magnetic ratchet along a radial direction. Consequently, a non-stepped rotation feel is provided.

Provided are a connector and a manufacturing method thereof. The connector is configured to dispose on a circuit board including a mounting hole. The connector includes a guide pin module and a conductive cover. The guide pin module is located on one side of the circuit board and includes a base, a metal guide pin, and a glass sealing layer. The base has a perforation hole corresponding to the mounting hole. The metal guide pin is inserted into the perforation hole and the mounting hole. The glass sealing layer is disposed at the perforation hole and wraps around part of the metal guide pin. The conductive cover is disposed at the mounting hole, connected to the top of the metal guide pin, and protrudes from the circuit board. The conductive cover is bonded to the circuit board by soldering to electrically connect the metal guide pin to the circuit board.

Connector and manufacturing method thereof

A limb rehabilitation and training system includes a horizontal position adjuster movably mounted at a bottom side of a base, an expansion rotary member mounted at the horizontal position adjuster, a shoulder joint traction mechanism linked to the expansion rotary member through a first arm segment robotic arm and a height adjuster, and an upper-limb rehabilitation device linked to the shoulder joint traction mechanism. The upper-limb rehabilitation device is able to rapidly be adjusted to fit the left arm or right arm through the horizontal position adjuster, the expansion rotary member, the first arm segment robotic arm and a shoulder positioning-lifting rotary member and. Further, by means of the shoulder joint traction mechanism, the user's stiffened shoulder joint can be timely moved for a separation distance, achieving the function of loosening the joint and facilitating performance of successive rehabilitation treatment or training.
