Embodiment Construction

[0010] Such as figure 1 Shown, a kind of speeding alarm device comprises magnet 1, coil 2, electric brush 3, electromagnet 4, armature 5, spring 6, working power supply 7, warning lamp 8 and warning bell 9, and coil 2 is connected on the axle shaft 10, The coil 2 is in the magnetic field of the magnet 1, the two ends of the coil 2 are connected with the brush 3, the brush 3 is connected with the electromagnet 4 to form a closed circuit, the armature 5 in the working circuit matches the electromagnet 4, the armature 5 and the spring 6 Connected, the armature 5, the spring 6, the warning light 8 and the warning bell 9 are connected with the working power supply 7 to form a working circuit.

[0011] During use, alarm device is installed on the automobile axle 10. When the car speeds up, the axle 10 will rotate very fast, thereby driving the coil 2 to rotate rapidly. The coil 2 cuts the magnetic force line in the magnetic field of the magnet 1, and an induced current is generated...

Abstract

The invention relates to an overspeed alarm which comprises magnets, a coil, electric brushes, an electromagnet, an armature, a spring, a working power supply, an alarm lamp and an alarm bell. The coil is connected with an axle and arranged in a magnetic filed of the magnets; both ends of the coil are respectively connected with the electric brushes which are connected with the electromagnet to form a closed circuit; and the armature in a working circuit is matched with the electromagnet and connected with the spring; and the armature, the spring, the alarm lamp and the alarm bell are sequentially connected with the working power supply 7 to form the working circuit. By the adoption of the structure, when a vehicle is overspeed, the axle can rotate extremely rapidly so that the coil is driven to rapidly rotate, move cutting magnetic lines of force in the magnetic field, and generate an induced current; accordingly, the electromagnet suctions the armature to switch on the working circuit, and the alarm lamp and the alarm bell simultaneously work to achieve the alarm aim.

Description

technical field [0001] The invention relates to an improvement of a vehicle alarm, in particular to an overspeed alarm. Background technique [0002] Automobile speeding has become a common phenomenon now, and existing speeding alarms are complex in structure and expensive. Contents of the invention [0003] The purpose of the present invention is to provide a simple structure, low-cost overspeed alarm. [0004] The object of the present invention is achieved like this: a kind of overspeed alarm, comprises magnet, coil, electric brush, electromagnet, armature, spring, working power supply, warning light and warning bell, and coil is connected on the axle, and coil is in the magnetic field of magnet Among them, the two ends of the coil are connected to the brush, and the brush is connected to the electromagnet to form a closed circuit. The armature in the working circuit matches the electromagnet, and the armature is connected to the spring. The armature, spring, alarm lam...
