4results about How to "Reduce thinning" patented technology

The embodiment of the utility model provides a rotary connection structure, a support and an electronic equipment accessory. The rotary connecting structure comprises a first connecting piece and a second connecting piece, wherein the first connecting piece comprises a first connecting part and a fixing part; the second connecting piece comprises a second connecting part and a movable part; the limiting piece is arranged between the fixed part and the movable part, the limiting piece and the fixed part are relatively fixed, and the movable part is movably connected with the limiting piece; the first connecting part and the second connecting part are used for being connected with a first external part, the first connecting part can be bent relative to the fixed part, and the second connecting part can be bent relative to the movable part and drives the movable part to move relative to the limiting part. The rotating connection structure can be bent without a rotating shaft without the rotating shaft, so that the rotating connection structure can be used as a rotating element of the bracket; therefore, the thickness of the rotating connection structure is reduced, and the technical effect of lightening and thinning is achieved.

The present invention relates to the field of key technology, and in particular to a key that can be lifted and retracted and a lifting key assembly having the key, which includes a base, a movable bracket and a keycap, wherein the base includes a key-lifting plate, a fixed plate and a movable plate arranged in sequence from top to bottom, the key-lifting plate is slidably arranged above the fixed plate, and the movable plate is slidably arranged below the fixed plate; the movable bracket includes a first bracket and a second bracket, one end of the first bracket is hinged to the fixed plate, and the other end of the first bracket is hinged to the keycap; one end of the second bracket is hinged to the movable plate, and the other end of the second bracket is hinged to the keycap; a lifting block is convexly provided on one side of the key-lifting plate close to the keycap. The present invention makes the keyboard thinner by realizing the lifting of the keycap, so that the key does not need to shorten the stroke of the key when in use, so that the key maintains the original comfort and feedback, while achieving the thinning of the keyboard and reducing the failure rate of the key.

This invention provides an integral forming apparatus and method for a corrugated, irregularly shaped thin-walled structure. The integral forming apparatus includes a spoke plate, a core mold, multiple petal molds, and an actuating ring. The core mold has multiple corrugated forming grooves along its circumference. The multiple petal molds are rotatably connected to the spoke plate and are spaced apart along the circumference of the spoke plate. Each petal mold has a boss that matches the shape of the forming groove. The actuating ring is sleeved on the outer periphery of the multiple petal molds and can move axially along the core mold, driving the multiple petal molds to converge towards the forming grooves, thereby forming the blank located between the petal molds and the forming grooves into a corrugated, irregularly shaped thin-walled structure. This invention features a simple process, good integrity, high forming accuracy, suitability for most commonly used thermoforming equipment, fast forming speed, fewer steps, and can greatly improve production efficiency.

This application provides an electrochemical device, an electrical device, and a charging device. The electrochemical device includes an electrode assembly and a charging circuit configured to receive a charge current and charge the electrochemical device. The first electrode plate includes a first current collector, a first active material layer disposed on a surface of the first current collector, and X first tabs, where X is an integer greater than 1, and the X first tabs and the first current collector are integrally formed. The second electrode plate includes a second current collector, a second active material layer disposed on a surface of the second current collector, and Y second tabs electrically connected to the second current collector, where Y is an integer greater than or equal to 1, and Y < X. The electrochemical device, the electrical device, and the charging device according to this application can avoid the loss of active materials, and avoid a series of problems caused by uneven thinning. In addition, compared with a multi-tab winding structure, the electrochemical device can keep the capacity and energy density from losing. Moreover, coupled with a pulse charging manner, the structure disclosed herein significantly improves the charging capabilities of the electrochemical device under low-temperature conditions.
