Abstract

The utility model discloses a trigger device of micro trigger pen, and belongs to the field of pressure trigger pens. The trigger device comprises a pen point, a spring, an elastic metal wire, a micro-pore conductive strip, a chassis and a wire, and further comprises an elastic conductive strip, when the pen point is suspended, the elastic metal wire and the micro-pore conductive strip are insulated with the elastic conductive strip, and when writing, the pen point gets lateral pressure or positive pressure to cause the deformation of the spring, and leads the elastic metal wire to move and contact the micro-pore conductive strip or the elastic conductive strip to form short circuit, thereby leading a signal generating circuit to judge the writing action of the pen according to the conducting condition and control signal transmission. The trigger device avoids error operation caused by friction and vibration, achieves pressure trigger in any direction, and lowers consumption of batteries.

Description

A kind of fine motion triggers the flip flop equipment of pen

Technical field

The utility model relates to a kind of fine motion and triggers pen, relates in particular to the flip flop equipment that a kind of fine motion triggers pen, belongs to a pressure activated field.

Background technology

Occurred in recent years a kind ofly on the computer projection screen, carrying out virtual book by light pen and writing technology and product with computer operation, patent No. ZL01108047.7, the patent of invention of patent name " System and method for that is used for computing machine coordinate and control information input " discloses correlation technique.In Related product was realized, the performance of electron luminescence pen was extremely important, and as a kind of virtual book writing tools, the electron luminescence pen needs to send signal according to the stress of nib sensitive and accurately.

Patent No. ZL03259582.4, the utility model patent of patent name " inducing luminous pen " discloses a kind ofly can respond to nib vibration when mobile and control luminous light pen implementation on screen, the defective of this scheme is: 1, the friction that holds a pen of user and rock and may cause maloperation, trigger insensitive if 2 screens are very smooth, 3, testing circuit needs continued power to work, and causes the battery consume more.

Other has a kind of product is the pressure activated pen that adopts microswitch, and its nib can move axially in a body, and contact with a touch-switch, and nib is subjected to positive pressure and can passes to touch-switch and make it to move when writing, thereby trigger pip is launched.The defective of this scheme is: pen usually needs to tilt firmly during actual the use, particularly when dragging setting-out backward, because nib is subjected to the positive pressure component very little and friction force is bigger, can cause switch triggering malfunctioning.

Summary of the invention

Problem to be solved in the utility model is to propose the flip flop equipment that a kind of fine motion triggers pen on the basis of existing pressure activated pen.

A kind of fine motion triggers the flip flop equipment of pen, its structure comprises: nib, spring, elastic metallic yarn, aperture conducting strip, base and lead, wherein: the aperture conducting strip is fixed on the base, one end of spring connects base, the other end connects nib, the diameter of section of elastic metallic yarn is slightly less than the hole diameter on the aperture conducting strip, one end of elastic metallic yarn is fixedly connected on the nib, pass the aperture on the aperture conducting strip after the elastic metallic yarn bending but do not touch with the aperture conducting strip, the aperture conducting strip is connected by lead.

The utility model is because be not vibration detection, so the maloperation of having avoided frictional vibration to cause; Because the written displacement of any direction can both cause elastic metallic yarn and aperture conducting strip or elastic conducting strip to touch, so can realize any direction pressure activated well; Disconnect under elastic metallic yarn and aperture conducting strip and the elastic conducting strip normality, touch when stressed, therefore can be directly as the power switch of signal transmission circuit or the trigger switch of working, be in no power consumption or little power consumption state when making whole electronic pen normality, can reduce battery loss greatly.

Description of drawings

Fig. 1 is a structural representation of the present utility model, the number in the figure title: 1, nib, 2, spring, 3, elastic metallic yarn, 4, the aperture conducting strip, 5, base, 6, elastic conducting strip, 7, lead.

Embodiment

As shown in Figure 1, a kind of fine motion triggers the flip flop equipment of pen, its structure comprises nib 1, spring 2, elastic metallic yarn 3, aperture conducting strip 4, base 5, elastic conducting strip 6 and lead 7, wherein: aperture conducting strip 4 is fixed on the base 5, one end of spring 2 connects base 5, the other end connects nib 1, the diameter of section of elastic metallic yarn 3 is slightly less than the hole diameter on the aperture conducting strip 4, one end of elastic metallic yarn 3 is fixedly connected on the nib 1, pass the aperture on the aperture conducting strip 4 after elastic metallic yarn 3 bending but do not touch with aperture conducting strip 4, behind elastic metallic yarn 3 other ends, be provided with the elastic conducting strip 6 that is fixed on the base 5, elastic metallic yarn 3 does not touch with elastic conducting strip 6, and aperture conducting strip 4 is connected by lead 7 with elastic conducting strip 6.

Nib 1 is that the copper pipe of a diameter 5mm connects a plastics cap for brush formation, and luminescent device is installed in the cap for brush; Spring 2 is tubular springs of an about 5mm of external diameter, steel wire diameter 0.8mm, high 6mm; The quantity of aperture conducting strip 4 is at least a slice, is that thickness is the copper sheet of 0.5mm, has the aperture of diameter 1.4mm above it; Elastic metallic yarn 3 is steel wires of a diameter of section 0.8mm, the bending of one end is welded on the copper pipe of nib 1, pass but do not touch two apertures on the aperture conducting strip, approximately the other end of 0.2mm does not touch in aperture conducting strip 4 backs with aperture conducting strip 4 and is welded on elastic conducting strip 6 on the base 5 in parallel; Base 5 is pcb boards, and we select two parallel being welded on the base 5 of aperture conducting strip, the parallel 20mm that is about for use apart; One end of spring 2 is welded on the base 5, and the other end welds with the copper pipe of nib 1; Lead 7 connects aperture conducting strip 4 and elastic conducting strip 6, and is connected to signal transmission circuit.

Whole apparatus structure be not subjected under the external force effect, and elastic metallic yarn 3 is guaranteed not touch with aperture conducting strip 4 and elastic conducting strip 6; When writing operation, nib 1 contacts with writing surface and stressed, cause spring 2 distortion, thereby being subjected to displacement, elastic metallic yarn 3 touches aperture conducting strip 4, when nib 1 is subjected to positive pressure, elastic metallic yarn 3 moves backward and touches with elastic conducting strip 6, triggers short circuit, and signal transmission circuit can come the control signal emission according to the action of writing of conducting situation differentiation pen.
