Ultra-small key structure device

Abstract

The invention provides an ultra-small key structure device which comprises key caps (1), an elastic body (11), a membrane switch piece (12), a support plate (15), an outer connection rod support (17b) and an inner connection rod support (17a). The ultra-small key structure device is characterized in that connection rod arms of the outer connection rod support (17b) and the inner connection rod support (17a) are respectively formed by a single reinforced bending edge (24) vertical to a connecting rod plate surface (21); connection rod upper cooperation portions (19) and connection rod lower cooperation portions (18) of the outer connection rod support (17b) and the inner connection rod support (17a) are arranged to the inner sides of the outer surfaces of the reinforced bending edges (24) respectively; support plate rotation portions (13) are arranged at the inner sides of the reinforced bending edges (24) of the outer connection rod support (17b) and the inner connection rod support (17a) respectively; and key cap slide portions (3) are arranged at the inner sides of the reinforced bending edges (24) of the outer connection rod support (17b) and the inner connection rod support (17a) respectively. According to the ultra-small key structure device, the size of a keyboard is reduced, and key caps are allowed to be arranged more beautifully.

Description

Technical field [0001] The invention involves a key switching device for the knock -knocking operation, which specializes in the key switching device loaded in the keyboard loaded in the input device of the electronic instrument. Background technique [0002] In the thin type of portable electronic devices such as laptop-type computer or palm-on-type computers, that is, the low height of the key switching device required to perform a hit operation is required, and it improves its operability that is good.The upper part of the board is to guide a pair of plastic link components of supporting keycaps, which corresponds to the switching mechanism of the contact part of the lift -down movement of the keycap.Through the transmission of the force of a pair of plastic connecting rod components, the keycaps can ensure that the keycaps can maintain the prescribed posture relative to the support plate and the substantial vertical direction, and at the same time, the linked support structur...

This limits the possibility of further shrinking the keys with the key switch device of the plastic linkage

[0007] Generally, all keys and direction keys of the F key (generally in the first row of the notebook keyboard) adopt a small and narrow structure. The minimum width of the keyboard is 8.2mm, and the English letters and numeric keys are generally 15mm-16mm, which causes the width of all the keys in the row where the space bar is located to reach 18mm-19mm, which is neither beautiful nor conducive to the further improvement of the keyboard size. Reduced, the existing small key with a width of 8.2mm (due to the pursuit of a small structure) has poorer rigidity of the support structure
