Abstract

The utility model relates to an alarm for a motorcycle kickstand, which is used for the theft-proof performance and the alarm of motorcycles or other vehicles. An electronic alarm and a kickstand touchdown switch are arranged on the kickstand of the motorcycle. The utility model which is combined with an existing theft-proof alarm for vehicles enhance the theft-proof safety of the vehicles. The utility model has the advantages of small size, reliable safety and sensitivity, and damage protection. When the motorcycle is moved a little by a stealer, the theft-proof alarm for a motorcycle kickstand can alarm. To lift away the entire motorcycle which is provided with theft-proof alarm for a motorcycle kickstand by stealers is impossible.

Description

Theft-proof alarm device for motorcycle kickstand

The utility model is a kind of motor bike support burglar alarm, belongs to vehicle anti-theft accessory class.

At present, most motor bike does not have antitheft alarm system, just by disconnecting oily circuit or wheel being pinned to take precautions against the car stealer, these modes just drive away for the car stealer or push away away the obstacle that vehicle is provided with, but can not stop the car stealer that car load is brought up to the behavior that automobile is stolen.So, although oily circuit all disconnects, adding crash-resistant lock again, the stolen phenomenon of generation motor bike is still and happens occasionally.

The purpose of this utility model provides a kind of simple and effective motorcycle anti-theft warning device, and it and existing various anti-joyride devices combine has increased the theft-proof safety of anti-theft.Need not start vehicle than as noted above car stealer and pry open lock, the direct pilferage mode that car load is lifted on the automobile, this device just can send loud chimes of doom in a flash what the car stealer moved vehicle, makes failing in one's scheme of car stealer.

Motorcycle stand annunciator of the present utility model is realized in the following manner.

Figure of description (1) is the lateral plan of annunciator;

Figure of description (2) is the front elevation of annunciator;

Figure of description (3) is the construction of switch scheme drawing that contacts to earth of annunciator;

Figure of description (4) is the circuit diagram of annunciator.

Can find out that by figure (1) and figure (2) warning circuit of the present utility model is installed In the assembling box (9) on motorcycle stand top, there are loudspeaker louver (10) and tap switch knob (11) in the side of assembling box (9), and assembling box (9) is welded on the steel pipe (1) of support.

Figure of description (3) is the construction of switch schematic diagram that contacts to earth of the utility model alarm. The switch that contacts to earth is made up of central shaft (7), spring (12), plastic washer (6), copper contact (5), plastics fixed mount (3), copper sheet (2) and shell (4). Copper contact (5) and plastic washer (6) are fixed on the central shaft (7) by screw thread, and copper contact (5) top is pressed with spring (12). Two copper sheets (2) are fixed on the plastics fixed mount (3), and plastics fixed mount (3) center is porose to be enclosed within on the central shaft (7), and spring (12) is pushed down. Plastic solid fixed rack (3) is fixed by screw thread with shell (4).

The switch principle of work of contacting to earth of the present utility model is such.Center shaft (7) can move up and down in the hole of shell (4) bottom He in plastics fixed support (3) centre hole, the mobile drive copper contact (5) of center shaft (7) and plastic washer (6) move, two copper sheets (2) are gone up mobile at copper contact (5) and plastic washer (6), just form on off state, when two copper sheets (12) move on the copper contact (5), just form path, move to just to form when plastic washer (6) is gone up and open circuit.

Embodiment: because the whole switch that contacts to earth is to be contained in the shell (4), and shell (4) is contained in the steel pipe (1) of motor bike leftover bits and pieces, block by toeguard (8), toeguard is welded on the steel pipe (1), so shell (4) can not drop out, each support has two pin, and the switch that contacts to earth is installed in every pin, and every switch all joins with warning circuit.Center shaft when motorcycle stand is propped up (7) moves up under the effect of gravity, make copper sheet (2) move on to plastic washer (6) position, two copper sheets are in off-state, there is not electric current to pass through, so warning circuit is not worked, and when the people lifts car or make support to lift or car tilted, the center shaft (7) of switch of contacting to earth on the rack leg makes copper sheet (2) get back to copper contact (5) under the effect of spring (12) and locates, make two copper sheets (2) form path, this moment, warning was sent in warning circuit work.

Motorcycle stand warning circuit of the present utility model adopts integrated circuit, shown in Figure of description (4).K in the circuit ₁And K ₂Be two switches that contact to earth of the present utility model, K is a tap switch, and this switch adopts digital control or lock control.Shown in the accompanying drawing 4 is digital control, has only the car owner to know which point is normal battle.IC is the warning integrated circuit, and y is a loud speaker, and E is the rechargeable type storage battery, the electrical generator of AB two termination motor bikes.Whole warning circuit is once packed into and is assembled in the box, is closed by riveting, weldering or bolt.

Except that the technology contents described in the specification sheets, be present technique field professional and technical personnel's known technology.
