Description

Key with pressing paragraph sense

Technical field

The utility model is related with key, particularly relates to a kind of key with pressing paragraph sense.

Background technique

Keyboard is broadly divided into mechanical keyboard and thin film type keyboard, for the operating habit of user, either which Kind keyboard has required significantly to press feel, and user can be allowed to know clearly pressing side when pressing keyboard Whether formula is correct, and can meet operational psychology and complete sense.

In other words, if the process in pressing keys can not obtain correct feedback impression from key, user will be because For that can not determine whether correctly to press and repetitive operation or blunt, cause using upper puzzlement.

There are many keys for being applied to keyboard to produce paragraph sense when pressing at present, is to pass through key mostly Key axis be pressed it is mobile during synchronize and compress elastic slice and generate flexible deformation, and then formed key it is mobile when paragraph effect Fruit.

But the higher cost of aforementioned metal elastic slice, production is more many and diverse with assembling process, what is more, due to metal elastic Piece often utilizes made by unlike material with the key key axis mutually compressed, holds after long-time friction contact between the two Easily lossy or damage situation, influences the normal effect of key.

Specific embodiment

First it is noted that the utility model provide with pressing paragraph sense key can be widely applied to it is various not The keyboard of same type, such as mechanical key or thin button, those skilled in the art should be able to understand in present embodiment The epigyny description for not limiting particular element or technical field, and quantity are belonged to about composition component, description lanuae etc. Term " one " is to contain one and more than one multiple element quantity.

Please referring initially to shown in Fig. 1 and Fig. 2, the utility model first preferred embodiment is said as an example with mechanical key Bright, having the key 10 of pressing paragraph sense includes a pedestal 20, a keycap 12, a linked component 30, a pusher shoe 40, Yi Jiyi Elastic component 50.Pedestal 20 there is one first accommodation groove 22 to abut with one be connected to the second accommodation groove 24 of the first accommodation groove 22, and second The horizontal extension of accommodation groove 24 can define a vertical plane 26 along the extending direction of the second accommodation groove 24.

Linked component 30 is set to the first accommodation groove 22, and the linked component 30 of this preferred embodiment includes that a key axis 32 is worn with one Set on the compressed spring 34 of 32 bottom center of key axis, the two of key axis 32 are opposite, and lateral wall is all equipped with a convex shape driving portion 36, drives The bottom side and top side in dynamic portion 36 are respectively provided with one first inclined surface 37 and the second inclined surface 38.Key axis 32 is plugged to the of pedestal 20 One accommodation groove 22, and the cover board 21 covered by one in pedestal 20 is contained in inside pedestal 20, compressed spring 34 is set to key axis 32 Inside, the elastic force of compressed spring 34 can push key axis 32, and keycap 12 is set to key axis 32 above cover board 21, so that keycap 12 can be with Key axis 32 moved back and forth up and down relative to pedestal 20.

Pusher shoe 40 is general in long strip, and pusher shoe 40 has one towards the supporting part 42 for extending laterally protrusion, and pusher shoe 40 is set In the second accommodation groove 24 of pedestal 20, it can be set to pedestal 20 in a manner of along 26 horizontal anomalous movement of vertical plane, support Portion 42 corresponds to the driving portion 36 of key axis 32, and pusher shoe 40 can be in a first position (as shown in Figure 3) and a second position (as schemed Shown in 4) between shift reciprocately.Elastic component 50 is set between the one side wall and pedestal 20 of pusher shoe 40, and elastic component 50 has elastic force Push pusher shoe 40 mobile towards first position direction.

By above-mentioned composition component, as shown in Figures 3 to 5, the key of linked component 30 is driven after keycap 12 is pressed Axis 32 moves down, and the driving portion 36 of key axis 32 is pressed against the supporting part 42 of pusher shoe 40 first with the first inclined surface 37, makes to elapse Part 40 can produce by the second position movement pushed towards such as Fig. 4 of taking advantage of a situation until driving portion 36 is separated from each other with pusher shoe 40 Paragraph sense is pressed out, and after key axis 32 persistently moves down, the elastic force of elastic component 50 makes pusher shoe 40 be moved back to such as Fig. 5 again One position, supporting part 42 are located at corresponding second inclined surface, 38 position.If keycap 12 is no longer pressed, key axis 32 and 12 energy of keycap It is driven and replys by the elastic force of compressed spring 34.

In order to allow 40 energy reciprocating movement of pusher shoe in pedestal 20, the elastic component 50 of the utility model be can be as shown in Figure 6 Compressed spring or foam as shown in Figure 7, silica gel, or as shown in Figure 8 with plastic material be made have deformation elastic force Bending member.

Since pusher shoe 40 and key axis 32 are all directly inserted in inside pedestal 20, basipetal assembling mode is more convenient With it is quick, save built-up time, pusher shoe 40 can make displacement stroke more smooth by the promotion of elastic component 50, press paragraph sense It is more clear.Elastic component 50 can adjust material according to the needs of different pressing strength, increase the alternative of pressing paragraph sense.Again Person, pusher shoe 40 are made with key axis 32 using same material, can be reduced friction loss when the two mutually compresses, and are extended and are used Service life.

For another example shown in Fig. 9 to Figure 14, the second preferred embodiment of the utility model be with thin button as an example, have press The key 60 for pressing paragraph sense is also in the linked component 63 of scissor form, a pusher shoe comprising a pedestal 61, a keycap 62, one 64 and an elastic component 65.After keycap 62 is pressed, the driving portion 66 of linked component 63 is equally first pressed against pusher shoe 64 Supporting part 67, push pusher shoe 64 mobile towards the second position such as Figure 13, until driving portion 66 and 64 phase of pusher shoe Mutually separation produces pressing paragraph sense, and after keycap 62 and linked component 63 persistently move down, the elastic force of elastic component 65 makes again Pusher shoe 64 is moved back to the first position such as Figure 14, and supporting part 57 is located at the top position of corresponding driving portion 66, keycap 62 no longer by Pressing, linked component 63 and keycap 62 can return back to original non-pressing state.

In addition as shown in Figure 15 to Figure 20, the utility model third preferred embodiment provides pressing with pressing paragraph sense Key 70 is generally same as first preferred embodiment, and feature is that pusher shoe 71 is hubbed at the second accommodation groove 73 of pedestal 72, elastic component 74 For torsional spring be set between pedestal 72 and pusher shoe 71, make pusher shoe 71 can along 75 original place beat of vertical plane, 76 movement of key axis Driving portion 77 can also be used afterwards and compress the supporting part 78 of pusher shoe 71, and then produce pressing paragraph sense.
