Abstract
The utility model discloses an electromagnetic braking type gearbox, which comprises a box body, an electromagnet, and a drive gear and a driving wheel, which are arranged in the box body, wherein, the electromagnet is arranged on the box body; a working beam is arranged on the electromagnet, and the driving wheel is provided with a braking hole. Under a braking state, the driving wheel is turned until the braking hole of the driving wheel faces the working beam, and the working beam is inserted into the braking hole. The electromagnetic braking type gearbox of the utility model has the advantages of rapid brake and high safety, thus being very suitable for being used on an electric baby carriage.
Description
Technical field
The utility model relates to the device on the perambulator, specifically a kind of electromagnetic brake formula gear case that is used on the electric children vehicle.
Background technology
The gear case of electric children vehicle does not have latch-up structure at present.When power cut-off or the connection of power supply end, transmission gear still can rotate.And this rotation of transmission gear brings following problem: the one, can't in time stop the perambulator in the motion; The 2nd, the perambulator that remains static, as meet external force, and to slide easily, safety is relatively poor.
Summary of the invention
The purpose of this utility model is to design a kind of electromagnetic brake formula gear case.
To be solved in the utility model is the gear case latch-up-free structure of existing electric children vehicle and the problem of this kind electric children vehicle poor stability.
The technical solution of the utility model is: it comprises casing, electromagnet, is located at transmission gear and power wheel in the casing, and electromagnet is loaded on the casing.Electromagnet is provided with working beam, has spoke hole on the power wheel.Under the braking state, power wheel forwards its spoke hole to and stretches in the spoke hole facing to working beam and working beam.
The utility model is braked rapid, safe advantage owing to be provided with power wheel latch-up structure electromagnet so have.This is that power wheel can't be rotated by locked with electromagnet because when connecting at power cut-off or power supply end, thereby guarantees that perambulator in the motion in time stops and the perambulator that prevents to remain static meets the slip that external force causes.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the utility model inner structure scheme drawing.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in the figure, the utility model comprises casing 2, electromagnet 6, is located at transmission gear 1 and power wheel in the casing 2.Electromagnet 6 is loaded on the casing 2.Electromagnet comprises coil, moving iron core and working beam 3, and working beam 3 is fixed on the moving iron core.Power wheel comprises first power wheel 4 and second power wheel 7, transmission gear 1 and second power wheel, 7 grinding tooths, second power wheel 7 and 4 engagements of first power wheel.On first power wheel 4, have spoke hole 8.During braking state, first power wheel 4 forwards its spoke hole 8 to and stretches in the spoke hole 8 facing to the position and the working beam 3 of working beam 3.Motor 5 is housed on the casing 2, on the motor shaft of motor 5, is provided with driving gear 9, driving gear 9 and 4 engagements of first power wheel.
Principle of work of the present utility model is: when energized, and moving iron core adhesive, working beam breaks away from spoke hole, and at this moment first power wheel 4 just can rotate.When power cut-off, moving iron core homing, at this moment working beam 3 ejects, when first power wheel 4 forwards its spoke hole 8 facing to working beam 3 to, working beam 3 just stretches in spoke hole 8, and at this moment first power wheel 4 just can not rotate, so transmission gear 1 does not just rotate yet.When not having energized, the position of working beam 3 is the same with position when the power cut-off.
