Description

The button of mechanical keyboard

Technical field

The utility model is related to input unit, more particularly, to a kind of simple in structure, at low cost and with mechanical feel The button of mechanical keyboard.

Background technology

Keyboard be divided into mechanical keyboard and and each of thin film type keyboard, the button of mechanical keyboard be using independent machine Tool formula switchs, and switch internal uses the principle of metalloid touch switch, built-in metal spring and shrapnel to control on keycap Lower movement makes contacting or disconnection, then by the metal haptic element of switch and the technique of rigid wiring board welding, realizes that signal leads to Wiring board is crossed to be transmitted and connect with master control borad, it is complicated, cost is high；Thin film type keyboard is then pushed away using keycap pushing Rod structure, push rod lower section setting one are similar to the bowl-shape silicone elastomer body of left-hand thread, and bosom is equipped with salient point, passes through silica gel The flexible deformation of body makes the film circuit board of salient point compressing lower section inside silica gel；Wherein, film circuit board is exactly by conductive material Be printed on plastic film, generally 3 slice structures, upper piece for anode, bottom sheet is cathode, the middle characteristic using plastic cement insulation Positive and negative anodes are separated, realizes that contact is connected under the action of silicone elastomer body and transmits signal, thin film type keyboard low cost, but Its button stability is poor, easily shakes, and can not obtain feel, greatly reduces the service life and experience sense of keyboard.

Utility model content

The shortcomings that overcome the prior art, the utility model aim are to provide a kind of simple in structure, at low cost and have The button of the mechanical keyboard of mechanical feel.

The utility model realized by following technical measures, a kind of button of mechanical keyboard, including bottom plate, the bottom plate On be provided with conductive film, be provided with hollow stent above the conductive film, accommodating one in the hollow stent is fastened on The silica gel button of conductive film upper surface, the hollow stent top are provided with a mechanical switch, the movement of the mechanical switch The upper end of axis is connected with a keycap, and the lower end of the shifting axle of the mechanical switch penetrates hollow stent and silica gel button upper end phase It supports.

As a kind of preferred embodiment, a light guide plate is additionally provided between the bottom plate and conductive film.

As a kind of preferred embodiment, a frame shape metal top cover, the mechanical switch middle part are provided on the hollow stent Boss is extended outward, the mechanical switch passes through frame shape metal top cover and held by boss and is erected on frame shape metal top cover.

As a kind of preferred embodiment, the silica gel button is one bowl-type, and one is overhang out by column under bottom of bowl mediad.

For the utility model due to being provided with conductive film on bottom plate, conductive film upper surface, which fastens, silica gel button, silicon Glue button is driven by a mechanical switch contradicts conductive film generation electric signal；Button is made to have in pressing using mechanical switch Splendid feel compresses thin film circuit so as to which admittance electricity be pressed to generate signal in pressing using silica gel button, and this structure is compared with machine For the metal contact switches of tool formula button there is advantage simple in structure, at low cost, have compared with silica gel-type button by pressure The paragraph sense (i.e. feel) gone.

Description of the drawings

Fig. 1 is the decomposition texture schematic diagram of the utility model embodiment.

Fig. 2 is the decomposition texture sectional view of the utility model embodiment.

Specific embodiment

With reference to embodiment and compare attached drawing the utility model is described in further detail.

Referring to figs. 1 to Fig. 2, including bottom plate 8, conductive film 6 is provided on the bottom plate 8 for a kind of button of mechanical keyboard, 6 top of conductive film is provided with hollow stent 4, and one is accommodated in the hollow stent 4 and is fastened on 6 upper surface of conductive film Silica gel button 5,4 top of the hollow stent is provided with a mechanical switch 2, the upper end card of the shifting axle of the mechanical switch 2 A keycap 1 is connected to, the lower end of the shifting axle of the mechanical switch 2 penetrates hollow stent 4 and offsets with 5 upper end of silica gel button.

For this button due to being provided with conductive film 6 on bottom plate 8,6 upper surface of conductive film, which fastens, silica gel button 5, silicon Glue button 5 drives conflict conductive film 6 to generate electric signal by a mechanical switch 2；Button is made to have in pressing using mechanical switch 2 There is splendid feel, thin film circuit is compressed so as to which admittance electricity be pressed to generate signal, this structure using silica gel button 5 in pressing Compared with having advantage simple in structure, at low cost for the metal contact switches of mechanical key, have compared with silica gel-type button and press The paragraph sense (i.e. feel) subdued.

It in the button of the mechanical keyboard of an embodiment, please refers to Fig.1 and Fig. 2, in order to which button generates luminous effect when in use Fruit, in front specifically it is also possible that be additionally provided with a light guide plate 7 between bottom plate 8 and conductive film 6 on the basis of technical solution, Hollow stent 4 is also transparent setting simultaneously.

In the button of the mechanical keyboard of an embodiment, please refer to Fig.1 and Fig. 2, it is specific on the basis of technical solution in front It is also possible that being provided with a frame shape metal top cover 3 on hollow stent 4,2 middle part of mechanical switch extends outward boss, institute Mechanical switch 2 is stated to be erected on frame shape metal top cover 3 across frame shape metal top cover 3 and being held by boss.

In the button of the mechanical keyboard of an embodiment, please refer to Fig.1 and Fig. 2, it is specific on the basis of technical solution in front It is also possible that silica gel button 5 is one bowl-type, one is overhang out by column under bottom of bowl mediad.

It is that the button of the utility model mechanical keyboard is expounded above, is used to help understand the utility model, but The embodiment of the utility model is simultaneously not restricted to the described embodiments, any to change without departing from what is made under the utility model principle Become, modification, substitute, combination, simplify, should be equivalent substitute mode, be included within the scope of protection of the utility model.
