Description

Heating type keyboard

Technical Field

The present invention relates to a computer input device, and more particularly, to a keyboard.

Background

Computers are increasingly being used in manufacturing and life, and computer input devices, such as keyboards, are also being developed. However, with current keyboards, no particular consideration is given to use in cold environments. In the actual use process, the problem of cold and stiff hands can be caused when people continuously use the keyboard in a cold environment, and the typing speed is influenced. In order to solve this problem, an external heating device is often used, and it is difficult to obtain a good heating effect because the external heating device is far from fingers placed on the keyboard.

On the other hand, the existing more keyboards adopt a key backlight design, so that the attractiveness of the keyboard is greatly improved. However, the lamp beads are arranged below the keys and only have a decoration effect, so that the functions are limited, and the hardware is wasted.

Disclosure of Invention

In view of the above problems, an object of the present invention is to provide a heat-generating keyboard, which not only can provide backlight for keys, but also can implement a function of heating fingers of a user at a low cost.

The technical scheme adopted by the invention for solving the technical problems is as follows: the keyboard comprises a base and an electric control module; the base is provided with key holes corresponding to the keys one by one; keys are arranged in the key holes; an elastic supporting structure is arranged between the key and the bottom of the key hole; a circle of light guide strips surrounding the keys are arranged on the inner peripheral surface of the key hole, heating lamp beads are arranged at the bottom of the key hole, and when the keys bounce upwards, the light guide strips can be illuminated by the illumination generated by the heating lamp beads; a longitudinal duct opposite to the heating lamp bead is arranged in the key; the inner wall of the longitudinal duct is formed by a light reflecting surface; when the key is pressed to the bottom downwards, the heating lamp beads enter the longitudinal hole, and at the moment, the illumination generated by the heating lamp beads can only be projected to the upper part of the longitudinal hole.

Preferably, the upper surface of the key is made of a translucent material at a portion opposite to the longitudinal hole. Furthermore, the semitransparent material is ground glass.

Preferably, the inner side surface and the inner bottom surface of the key hole are made into reflecting surfaces.

Preferably, the elastic supporting structure is a silica gel bulge made on the silica gel film, and the bottom of the silica gel bulge is provided with a conductive silica gel pad; two layers of thin film circuit boards are laid below the silica gel film, the silica gel bulge sinks under the pressing action of the key, and when the conductive silica gel pad presses the circuit nodes on the two layers of thin film circuit boards, the two layers of thin film circuit boards are conducted at the positions of the circuit nodes, so that the electronic control module obtains a key position signal; the heating lamp beads are arranged above the silica gel film, and the silica gel film and the silica gel protruding surface are both made into reflecting surfaces.

Preferably, a photosensitive sensor is arranged on the inner side wall of the key hole, and when the key floats upwards, the illumination of the heating lamp bead can be collected by the photosensitive sensor; and the key sinks, so that when the heating lamp bead completely enters the longitudinal hole, the illumination of the heating lamp bead is interrupted by the side wall of the key, and the photosensitive sensor generates an interrupt signal, so that the electric control module obtains a key position signal. Furthermore, the elastic supporting structure is a silica gel bulge or a spring structure.

Preferably, the longitudinal duct is rectangular, and the bottom end of the longitudinal duct is provided with a one-way door which is horizontally arranged in a natural state and can only be turned up above the longitudinal duct; the lower surface of the one-way door is made into a reflecting surface; therefore, when the key floats upwards, the illumination of the heating lamp beads is restricted between the key and the key hole, and the space is heated, so that the heat is saved, and the backlight is enhanced; when the key is sunk, the light can be concentrated in the longitudinal hole channel to heat the finger.

The invention has the beneficial effects that: when the keyboard is used, if the keys are not pressed down, the heating lamp beads emit light to irradiate the light guide strips on the inner peripheral surface of the key holes directly or after the light is reflected in the key holes, so that background light bands surrounding the keys are formed, and the effect of beautifying the keyboard is achieved; when the key is pressed down, the heating lamp beads are completely embedded into the longitudinal hole, so that the light emitted by the heating lamp beads can be intensively irradiated on the finger above the key, and an obvious heating effect is formed.

Detailed Description

The invention is further illustrated with reference to the following figures and examples:

the first embodiment is as follows:

the keyboard comprises a base and an electric control module; the base is provided with key holes corresponding to the keys one by one. Wherein, each key hole and partial structure of the key are shown in fig. 1, and a key 2 is arranged in each key hole 10; an elastic supporting structure is arranged between the key 2 and the bottom of the key hole 10; a circle of light guide strips 4 surrounding the key 2 are arranged on the inner peripheral surface of the key hole 10, a heating lamp bead 5 is arranged at the bottom of the key hole 10, and when the key 2 is bounced upwards, illumination generated by the heating lamp bead 5 can illuminate the light guide strips 4; a longitudinal duct 22 opposite to the heating lamp bead 5 is arranged in the key 2; the inner wall of the longitudinal duct 22 is formed by a light reflecting surface, so that the loss of illumination can be reduced; when the key 2 is pressed to the bottom downwards, the heating lamp beads 5 enter the longitudinal hole 22, and at the moment, the illumination generated by the heating lamp beads 5 can only be projected above the longitudinal hole 22, so that the illumination is concentrated, and the effect of heating the fingers is achieved.

In the first embodiment, the elastic supporting structure is a silica gel protrusion 31 formed on the silica gel membrane 6, and a conductive silica gel pad 30 is disposed at the bottom of the silica gel protrusion 31; a two-layer thin film circuit board structure 7 is laid below the silicone membrane 6, the silicone bump 31 sinks under the pressing action of the key 2, and when the conductive silicone pad 30 presses the circuit node on the two-layer thin film circuit board 7, the two-layer thin film circuit board 7 is conducted at the position of the circuit node, so that the electronic control module obtains a key position signal; the structure is a general structure of most silica gel keyboards at present, and the specific details are irrelevant to the gist of the invention, so the details are not repeated. Reflective surfaces are made on the surfaces of the silica gel film 6 and the silica gel protrusions 31, so that the illumination loss of the heating lamp beads 5 can be reduced, and the illumination is reflected to the light guide strips as much as possible.

When the keyboard is used, if the key 2 is not pressed, the heating lamp beads 5 emit light which is directly or indirectly reflected in the key hole 10 and then irradiates the light guide strip 4 on the inner circumferential surface of the key hole 10 to form a background light band surrounding the key 2, so that the keyboard has the effect of beautifying the keyboard; when the key 2 is pressed down, the heating lamp beads 5 are completely embedded into the longitudinal hole 22, so that the light emitted by the heating lamp beads can be intensively irradiated on the finger above the key 2, and an obvious heating effect is formed.

In addition, the upper surface of the key 2 is made of a translucent material at the part opposite to the longitudinal hole 22, so that the energy of illumination can be converted into heat at the translucent material to heat the keyboard key 2. The semitransparent material is ground glass 21, and has a good heat-conducting property. The inner side surface and the inner bottom surface of the key hole 10 are made into reflecting surfaces, so that the illumination of the heating lamp beads 5 can be reflected, the loss of illumination is reduced, and the heating efficiency is improved.

The longitudinal duct 22 is rectangular, and the bottom end of the longitudinal duct is provided with a one-way door 23 which is horizontally arranged in a natural state and can only be turned up above the longitudinal duct; the lower surface of the one-way door 23 is made into a reflecting surface; therefore, when the key 2 floats upwards, the illumination of the heating lamp bead 5 is limited between the key 2 and the key hole 10, and the space is heated, so that the heat is saved, and the backlight is enhanced; when the key 2 is sunk, the light can be concentrated in the longitudinal hole 22 to heat the finger.

Example two:

the second embodiment of the heat-generating keyboard is different from the first embodiment in that: two layers of thin film circuit boards, silica gel films and silica gel bulges in the first embodiment are abandoned, only the spring structure 32 is adopted as the elastic supporting structure, the inner side wall of the key hole 10 is provided with the photosensitive sensor 8, and when the key 2 floats upwards, the illumination of the heating lamp bead 5 can be collected by the photosensitive sensor 8; and the key 2 sinks, so that when the heating lamp bead 5 completely enters the longitudinal duct 22, the illumination of the heating lamp bead 5 is interrupted by the side wall of the key, and the photosensitive sensor 8 generates an interrupt signal, so that the electric control module obtains a key position signal.

The second embodiment greatly simplifies the electrical structure under the keys, and the waterproof performance of the keyboard is greatly improved after two layers of thin film circuit boards laid in a large area are abandoned.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, but rather as the subject matter of the invention is intended to cover all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.
