摘要： The embodiments of this application provide a keyboard, including a keyboard base and a key, and the key includes a keycap and a key holder, where the keyboard further includes a driving portion, and the driving portion includes a driving board, a first mating member, and a second mating member, where the first mating member and the second mating member are arranged on the driving board; the driving board moves in a first direction relative to the keyboard base through the second mating member; and the key includes a key mating member, and when moving in the first direction, the driving board drives the first mating member to move relative to the key mating member to drive the key to descend. The driving portion drives the key to descend, so that the height of the keyboard can be designed to be smaller, and when the keyboard is applied to the electronic device, the thickness of the electronic device can be reduced. For a single keyboard product, the reduced height of the keyboard also facilitates stacking during processing and transportation, thereby saving space.

摘要： An activation assembly (10, 10a, 10b, 10c, 10d, 10e, 10f, 10g) is configured to be assembled with a substrate (30) and a keycap (50). The activation assembly (100) includes a flexible guiding component (100, 100a, 100b, 100c, 100d, 100e, 100f, 100g) and an elastic component (200, 200a, 200b, 200c, 200d, 200e, 200f, 200g). The flexible guiding component includes a covering portion (110, 110a, 110b, 110c, 110d, 110e, 110f, 110g), a first contact portion (120, 120a, 120b, 120c, 120d, 120e, 120f, 120g), and a second contact portion (130, 130a, 130b, 130c, 130d, 130e, 130f, 130g). The covering portion has a plurality of openings (O). The covering portion is configured to be mounted on the substrate. The first contact portion and the second contact portion are respectively located at two opposite sides of the covering portion. The elastic component includes a coupling portion (210, 210a, 210b, 210c, 210d, 210e, 210f, 210g) and a plurality of support portions (220, 220a, 220b, 220c, 220d, 220e, 220f, 220g). The coupling portion is connected to the covering portion. The support portions are connected to the coupling portion and are respectively located in the openings.

摘要： A controller (100) includes a key top (10), a substrate (30), and an elastic member (20). The elastic member is provided between the key top and the substrate. The elastic member includes a pressed portion (23), a base (29), a skirt portion (24), and a pressing member (70). The substrate includes a contact (50). A direction in which the key top and the elastic member are layered is defined as a first direction (101). A direction perpendicular to the first direction is defined as a second direction (102). When viewed in the first direction, the pressing member is surrounded by an outer peripheral edge of a prescribed region (63). In the second direction, a distance between an end of the outer peripheral edge of the prescribed region on a side of a swing center of the key top and an end of a top surface (71) on the side of the swing center is longer than a distance between an end of the outer peripheral edge of the prescribed region opposite to the swing center and an end of the top surface opposite to the swing center. In the second direction, the contact is located closer to the swing center than the top surface.
