Description

Technical Field

[0001] The utility model belongs to the technical field of keyboards, and in particular relates to a mini keyboard which is easy to carry. Background Art

[0002] The keyboard consists of a bottom shell + PCB + positioning board. In order to facilitate carrying the keyboard, flexible keyboards and folding keyboards are generally used, among which flexible membrane keyboards are a typical form of flexible keyboards. The reason why this type of membrane keyboard is called flexible is that the mask layer, isolation layer, and circuit layer of the membrane keyboard are all composed of software films of various properties.

[0003] In the Chinese utility model patent application number CN201921142916.5, entitled A portable mini keyboard, the soft rubber is rolled into the casing through a reel by rotating the limit knob at one end of the casing for storage, thereby reducing the footprint of the keyboard and making the keyboard convenient to use. The battery embedded in the reel is convenient for supplying the entire keyboard with electronic equipment. However, when the existing flexible keyboard is rolled up, the keys on the keyboard will rub against the keyboard, causing damage to the keys. At the same time, the flexible keyboard will roll into multiple circles when rolled up. During this process, the keys will be pressed on the keyboard, causing the key reset mechanism to be always under stress. After the flexible keyboard is detached from the casing, the keys may not rebound, causing damage to the keyboard. Utility Model Content

[0004] The purpose of the utility model is to provide a portable mini keyboard to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a mini keyboard that is easy to carry, comprising: a winding shell, a flexible keyboard and a winding component, the winding component is formed with a winding space for winding up the flexible keyboard, a winding seat is provided in the winding space, the winding seat is distributed in a multi-turn spiral state along the axis of the winding space as the axis, a spiral storage gap is formed in the winding seat for winding and storing the flexible keyboard, and the spiral storage gap is greater than the thickness of the flexible keyboard.

[0006] Preferably, a winding bin is provided inside the winding shell, an opening extending into the winding bin is provided outside the winding shell along a tangent position, and the winding space is formed in the winding bin and the opening.

[0007] Preferably, a guide rail is provided on the inner wall of the winding seat along a spiral path, one end of the guide rail extends into the opening, a slide groove is provided at the bottom of the flexible keyboard along the storage direction, and at least a portion of one end of the guide rail is arranged in the slide groove.

[0008] Preferably, a winding mechanism is also installed in the winding bin, and the winding mechanism is used to drive the flexible keyboard to be rolled into the winding bin.

[0009] Preferably, the winding mechanism includes a rotatable wire wheel, which is rotatably mounted on the axis of the winding bin, and a connecting buckle and a pull rope are sequentially mounted between the flexible keyboard and the wire wheel, and the pull rope is arranged in a spiral storage gap in the winding seat.

[0010] Preferably, a rotating shaft for driving the wire wheel to rotate is also installed on the winding shell, and mounting holes are installed on the inner walls on both sides of the winding bin symmetrically, and both ends of the rotating shaft are rotatably installed in the mounting holes on both sides respectively. A knob connected to one end of the rotating shaft is provided on the outside of the winding shell, and a rotating groove for rotating the knob is opened on the winding shell.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] (1) The utility model adds a winding seat in the winding shell. Since the winding seat has a multi-turn spiral structure, when the flexible keyboard is stored on the winding seat, the flexible keyboard will not be rolled up and squeezed on itself, thereby preventing the keys on the flexible keyboard from always being in a state of being pressed. At the same time, the spiral structure of the winding seat prevents the flexible keyboard from being over-rolled when winding, thereby increasing the service life of the flexible keyboard.

[0013] (2) The utility model adds a slide groove and a guide rail to allow the bottom surface of the flexible keyboard to be rolled up and stored on the inner wall of the spiral structure of the winding seat. At this time, the keys on the flexible keyboard will not contact the inner wall of the winding seat, thereby avoiding friction between the keys and the winding seat, thereby increasing the service life of the keys.

[0014] (3) The utility model adds a wire wheel, a pull rope, a rotating shaft and a knob. When the knob and the rotating shaft drive the wire wheel to rotate, the pull rope is driven to be wound around the wire wheel, thereby facilitating the winding of the flexible keyboard into the winding bin.
