  • Patent number: 10994620
    Abstract: An electric bicycle and a battery lift mechanism and a battery carrying device thereof are disclosed. The battery lift mechanism includes a bracket, a carrier for carrying a battery, an upward-force device coupling with the carrier, and a locking device selectively in an unlocked state or a locked state. The carrier is movable relative to the bracket along an up-down path; the upward-force device is capable of applying an upward force to the carrier. When the locking device is in the locked state, the locking device interferes with the battery to limit the relative movement between the battery and the bracket. When the locking device is in the unlocked state, the interference between the locking device and the battery is removed, so that the upward-force device drives the carrier carrying the battery to move upward relative to the bracket.

  • Patent number: 10211006
    Abstract: An illuminated keyswitch includes a base, a keycap, a lift mechanism, and a light source. The keycap includes a cap body and a light guiding rod. The lift mechanism is connected to between the light guiding rod and the base, such that the keycap can vertically move relative to the base through the lift mechanism. The light source is disposed between the light guiding rod and the base and emits light toward the light guiding rod. The light enters the light guiding rod through an end portion of the light guiding rod and then emits out the light guiding rod from another end portion of the light guiding rod and a side surface adjacent to the another end portion toward the cap body. Thereby, the whole cap body can receives relatively uniform back light.

  • Patent number: 10128063
    Abstract: A keyswitch uses a combination of springs connected in serial for providing a return force to a keycap of the keyswitch. When the keycap moves toward a base of the keyswitch beyond a transition position, one of the springs stops continuously deforming. It leads to an increment of the elastic coefficient of the combination of springs and an increment of the elastic stored energy by the combination of springs. Therefore, during a pressing on the keycap, the keycap can provide a light force feedback and then a heavy force feedback to a user. Further, the keyswitch can use a switch with a lateral motion, which can reduce influence of a resilient force produced by the switch on the up and down movement of the keycap. The keyswitch also can use an elastic piece disposed beside the keycap, which can provide a tactile feedback to the user.

  • Patent number: 10008345
    Abstract: A keyswitch includes a board having a first magnetic portion and a pivot portion, a cap, a switch, and a support device including a first support member having first and second bodies connected to each other via an elastic connection arm. The first body has first and second end portions connected to the cap and the pivot portion respectively. The second body has a second magnetic portion and a triggering portion. A U-shaped slot is formed around the triggering portion to make the triggering portion form an elastic cantilever arm extending from the second body. When the cap is pressed to make the second magnetic portion away from the first magnetic portion at a specific distance, the triggering portion triggers the switch. When the cap is released, a magnetic force between the first and second magnetic portions drives the second magnetic portion to approach the first magnetic portion.

  • Patent number: 10002725
    Abstract: A keyswitch includes a board, a cap, and a support device. The board has first and second bending members and a main body extending along X and Y axes perpendicular to each other. An included angle between a first abutting surface of the first bending member and the X-axis and an included angle between a second abutting surface of the second bending member and the X-axis are greater than 0°. The support device includes first and second support members having first and second hook structures respectively. When the cap is pressed, the first and second hook structures slide on the first and second abutting surfaces respectively to deform the first and second hook structures. When the cap is released, the deformed first and second hook structures drive the first and second support members to slide relatively for making the cap return to a non-pressed position.

  • Patent number: 9984840
    Abstract: A keyswitch structure includes a base, a keycap, a frame disposed between the base and the keycap for providing a supporting and moving mechanism to the keycap, and another frame interacting with the former frame through a magnetic attraction force. When the keycap is not pressed, the magnetic attraction force drives the two frames to stably stand on the base and form a stable supporting structure, so that the keycap is located at a farther position relative to the base. When the keycap is pressed with an external force to move toward the base, the magnetic attraction force is overcome so that the two frames depart from each other; that is, the above stable supporting structure is temporarily destroyed. Once the external force applied to the keycap is eliminated, the two frames will form the stable supporting structure again due to the magnetic attraction force.

  • Patent number: 9715973
    Abstract: A keyswitch includes a board, a cap, and a support device. The support device is disposed between the board and the cap and includes first and second support members movably connected to the cap and the board. A stopping member is formed on one of the first support member and the cap. An elastic member is formed on the other one of the first support member and the cap. When the cap is not pressed, the stopping member abuts against the elastic member to keep the cap at a non-pressed position. When the cap is pressed to a pressed position, the cap and the first support member slide relatively to make the stopping member deform the elastic member. When the cap is released, the elastic member drives the cap and the first support member to slide relatively, so as to move the cap back to the non-pressed position.
