Abstract

The utility model relates to a warning device with improved structure, which is designed for the purposes of convenient installation, convenient disconnection, and portability. The warning device with improved structure comprises a main body, a seat, and a light emitting device, wherein, screw threads are arranged on the bottom edge inside the main body; the seat is a table seat which is screwed and fixed inside the main body through a screw buckle on the external edge of the table seat; an L-shaped rib is arranged on the across corners of the top surface of the table seat; a concave cell holder is arranged downwards on the periphery of the top surface of the table seat; the light emitting device is a circuit board which is arranged in the area of the table surface corresponding to the L-shaped rib; the circuit board has light emitting elements and a light emission control circuit which is controlled by a light sensitive element. The light emitting element can be controlled to warn by flickering without light irradiation, with capability of using a power of alternating current or direct current.

Description

Improved structure warning device

The utility model relates to a kind of telltale, relates to a kind of attention device or rather.

Existing attention device is divided into two kinds of versions substantially, and a kind of is on circular cone tube main body reflecting strips to be set, and produces reflectively when car light irradiation, has passive caution effect; Another kind is that illuminating circuit is set in main body, needn't be by the car light irradiation of road through vehicle, can be luminous automatically night, and play initiatively warning function.Yet this mostly heavy inconvenience of attention device that can be luminous is carried, and assembling and dismounting all are difficult for and only can use direct current supply, more than all use inconvenience problems that causes attention device.

The purpose of this utility model is that traditional illuminating warning device structure is made improvements, particularly base structure makes improvements, have easy to assembly, dismounting easily, the characteristics of AC/DC, good warning effect, can be used to warn passerby or car immediately when running into driving faults or traffic hazard taking place.

Attention device of the present utility model is constituted by main body, pedestal, light-emitting device, it is characterized in that:

1) described body interior lower edge is provided with screw thread;

2) on the described pedestal pedestal is arranged, the spiral shell button that is spirally connected with the main body internal thread is arranged on the outer rim of pedestal bottom, place, pedestal end face diagonal angle is provided with pair of L type rib, is arranged with battery tray downwards around the pedestal end face, respectively is provided with shell fragment on battery tray two minor faces;

3) described light-emitting device is the circuit board that contains luminescent device, and circuit board is embedded on the described pedestal in the L shaped rib The corresponding area.

Pedestal can be spirally connected fixing according to being threaded in the main body in the main body, the luminescent device on the light-emitting device glimmers luminous under the photosensitive control circuit effect.

Describe technology of the present utility model in detail below in conjunction with the embodiment accompanying drawing.

Fig. 1 is an attention device decomposition texture synoptic diagram.

Fig. 2 is an attention device unitized construction cut-open view.

Fig. 3 is a light-emitting device circuit structure embodiment block diagram.

Fig. 4 is the circuit diagram of light-emitting device circuit structure embodiment one.

Fig. 5 is the circuit diagram of light-emitting device circuit structure embodiment two.

Referring to Fig. 1, Fig. 2, attention device is made of main body 10, pedestal 20 and light-emitting device 30, and main body 10 is the conic tube of a light-permeable, and the inner barrel lower edge is provided with several circle screw threads 11, and it is solid that abutment body 20 screws in spiral shell.Main body 10 bottoms are sticking if be embedded several piece magnetic thing 12, make main body 10 adsorbable on metal.

Pedestal 20 is provided with pedestal 21, has suitable height.The end face diagonal angle of pedestal 21 is provided with L type rib 211, is arranged with several battery trays 22 downwards around the pedestal 21, and respectively establishes a shell fragment 221 on 22 liang of minor faces of battery tray, and battery V powers to light-emitting device 30 by shell fragment 221; AC power also can be introduced by shell fragment 221.

The control circuit of light-emitting device 30 is arranged on the circuit board 31, and several luminescent devices 32 are arranged on the circuit board 31, and other has light activated element 33 to reach other electronic components of the formation oscillatory circuit of serial connection with it.Circuit board 31 just can place in L type rib 211 The corresponding area of pedestal 21.When the circuit board 31 that is provided with light-emitting device 30 is embedded on pedestal 21 end faces of pedestal 20, can utilize gummed, screw togather, mode such as welding, circuit board 31 is fixed in the pedestal L type rib 211, and connect the shell fragment 221 of battery tray 22, thereby finish combining of pedestal 20 and light-emitting device 30 with lead E.

When using attention device, battery V is placed in the battery tray 22 of pedestal 20, or AC power is connected in the direct power supply that transmits on the shell fragment 221.Whole pedestal 20 screws in the main body 10 according to the screw thread 11 of main body 10.201 is the spiral shell button at outer rim place, pedestal 20 bottom among the figure.The magnetic thing 12 of main body 10 can place on the forward and backward deck lid of vehicle with absorption caution traffic attention device.When dull thread shone, the luminescent device flicker in the attention device was luminous.

Referring to Fig. 3, emission control circuit comprises light activated element 301, oscillatory circuit 302 and luminescent device 303.When environment has illumination, oscillatory circuit 302 failure of oscillations, luminescent device goes out, no warning function, environment is unglazed according to the time, oscillatory circuit 302 vibration, the luminescent device flicker is luminous to be shown to warn.

Referring to Fig. 4, light activated element CDS, transistor Q1, Q2, resistance R, capacitor C are formed oscillatory circuit.D1, D2 are light emitting diode.Oscillatory circuit work during unglazed the photograph, D1, D2 are luminous by the oscillation frequency flicker.Emission control circuit can also can be powered after diode bridge, electric capacity rectification, filtering by exchanging AC by direct current DC power supply.When illumination was arranged, the light activated element internal resistance was minimum, and Q1 ends, and oscillatory circuit is not worked, and D1, D2 go out.

Referring to Fig. 5, the difference of Fig. 5 and Fig. 4 is that to send optical diode D1, D2 elsewhere be luminotron M, and has increased driving transistors Q3.

The utility model has the advantages that: 1) easy to carry, the little and main body of volume and the separable placement of pedestal do not take up space; 2) fast changeable battery only needs place battery in the battery tray of pedestal or connect alternating current The source gets final product whole pedestal again according to being threaded in the main body of main body; 3) easy to use, when meeting emergency traffic accident or vehicle trouble, can be located at immediately in the caution district or before and after being adsorbed on the car bonnet because of easy to carry; 4) good warning effect, luminescent device concentrate on the circuit board, and brightness is concentrated, and warning mark is obvious.
