CN2823453Y - Warning key - Google Patents

Abstract

The utility model relates to a warning key. A main body of the utility model is a key (6), the tail part of the key is provided with a luminous tube (2) and a plastic handle (5) of a battery and a switch (1). A control circuit which is composed of a vibration sensor (7) and a controllable oscillating circuit (8) is also arranged in the plastic handle (5), the vibration sensor (7) is connected with the control end of the oscillating circuit (8), and the output end of the oscillating circuit (8) is connected with a luminous tube (2). After the utility model uses the control circuit, as long as a bicycle generates oscillation, the luminous tube can flicker and emit light. Accordingly, the utility model has a warning function on a rear vehicle, and simultaneously, the ornamental performance and the interesting performance of the key are increased.

Description

The caution key

Technical field

The utility model relates to a kind of bicycle lock key, is specifically related to a kind of bicycle lock key with caution and decoration functions.

Background technology

Unblank for convenience, a kind of Key with lamp is arranged now, luminous tube is housed, pin press button, can light luminous tube and play illuminating effect in key tail.But this Key with lamp, it is luminous to glimmer, not caution and decoration functions.

Summary of the invention

The purpose of this utility model is to propose a kind of caution key, this key makes luminous tube have the luminous function of flicker, so that front vehicle can be increased warning function by increasing some simple control circuits, simultaneously also decoration function can be arranged, increase the interest and the novelty of key.

A kind of caution key of the present utility model, its main body is a key 6, be provided with the plastic handgrip 5 that luminous tube 2, battery, switch 1 are housed in key tail, the control circuit of being made up of vibrating sensor 7 and controllable oscillatory circuit 8 is housed in plastic handgrip 5, vibrating sensor 7 is connected with the control end of controllable oscillatory circuit 8, and the output of controllable oscillatory circuit 8 is connected with luminous tube 2.

Advantage of the present utility model is: after having adopted control circuit, as long as bicycle produces vibrations, luminous tube will glimmer luminous, thereby front vehicle is played warning function, has also increased the ornamental of key simultaneously with interesting.

Description of drawings

Now the utility model is described in further detail in conjunction with an embodiment and accompanying drawing thereof.

Fig. 1 is the front schematic view of key of the present utility model;

Fig. 2 is cut-away view of the present utility model (removing the plastic handgrip panel).

Among the figure: 1 rotary switch, 2 luminous tubes, 3 printed circuit board (PCB)s, 5 plastic handgrips, 6 keys, 7 vibrating sensors, 8 controllable oscillatory circuit.

Embodiment

As Fig. 1 and Fig. 2, the control circuit of being made up of vibrating sensor 7 and controllable oscillatory circuit 8 is housed in the afterbody plastic handgrip 5 of caution key of the present utility model, button cell (is positioned at the back of circuit board, not shown in the figures) link to each other with control circuit by switch 1, vibrating sensor 7 is connected with controllable oscillatory circuit 8 control ends, and the output of controllable oscillatory circuit 8 is connected with 2 light emitting diode 2a, 2b being located at plastic handgrip 5 both sides.Vibrating sensor 7 is on sale with controllable oscillatory circuit 8 markets, can be assembled on the printed circuit board 3, referring to Fig. 2.

During use, rotary switch 1 is threaded to " ON " position, as long as this moment is the vibrations of vibrating sensor 7 when detecting cycling, controllable oscillatory circuit 8 just can make luminous tube 2 conductings at intermittence and glimmer the luminous several seconds, still exist as vibrations, controllable oscillatory circuit 8 starting of oscillation once more, luminous tube 2 glimmers the several seconds once more; In case bicycle stops, vibrating sensor 7 detects less than vibrations, and controllable oscillatory circuit 8 failure of oscillations, luminous tube 2 also stop flicker.As time spent not,, turn off power supply and get final product as long as rotary switch 1 is threaded to " OFF ".

By bike, the luminous key that glimmers can play warning function to front vehicle, helps traffic safety, also can play decoration function to key on the road of illumination deficiency, increases the interest and the novelty of key.

Claims (2)

1. warn key for one kind, its main body is a key (6), be provided with in key tail luminous tube (2) is housed, the plastic handgrip (5) of battery, switch (1), it is characterized in that in plastic handgrip (5), also being equipped with the control circuit of forming by vibrating sensor (7) and controllable oscillatory circuit (8), vibrating sensor (7) is connected with the control end of controllable oscillatory circuit (8), and the output of controllable oscillatory circuit (8) is connected with luminous tube (2).

2. caution key according to claim 1 is characterized in that described luminous tube (2) is 2.
