Abstract
The utility model discloses an intelligent brake mechanism, including switch, electric telescopic device and brake round pin, switch and electric telescopic device are connected through the wire, and brake round pin one end links to each other with electric telescopic device, and the other end cooperatees with the wheel locking groove, and the brake round pin radially is equipped with the arch, should protruding and contact switch contact cooperation. The utility model discloses an intelligence brake mechanism convenient operation, simple structure.
Description
Technical field
The utility model relates to a kind of braking mechanism.
Background technique
The braking mechanism of existing perambulator generally comprises pedal, driving component, brake pin and is provided with the wheel of locking slot, and pushes pedals can realize wheel lock and losing lock function continuously.
A kind of braking mechanism is disclosed as Chinese patent 200520077458.3, comprise the wheel joint, be arranged on the wheel on the wheel joint, be arranged on the brake handle on the wheel joint rotationally, have a plurality of locking slot on the wheel, be provided with driving component rotationally on the wheel joint, be provided with driving mechanism between brake handle and the driving component, be the brake pin spiral chute that has at least two blind holes on the circumferencial direction in the center of circle with the center of rotation of driving component on the driving component, brake pin spiral chute has at the bottom of the brake pin spiral chute, at the bottom of this brake pin spiral chute is what tilt, be the spline pin spiral chute that also has a plurality of blind holes on the circumferencial direction in the center of circle with the center of rotation of driving component on the driving component, spline pin spiral chute has at the bottom of the spline pin spiral chute, for what tilt, be provided with a spline pin axially slidably on the wheel joint at the bottom of this spline pin spiral chute.This braking mechanism have only the people for trample brake the time, just can realize brake, operation is inconvenient.
Summary of the invention
The utility model provides a kind of braking mechanism easy to operate, simple in structure.
A kind of intelligent braking mechanism, comprise switch, electrical retractor and brake pin, switch is connected by lead with electrical retractor, brake pin one end links to each other with electrical retractor, the other end matches with the wheel lock groove, the brake pin radially is provided with projection, this projection and contact switch contact matching.
As a kind of improvement of the present utility model, described brake pin places in the key seat, and the brake pin can be done horizontal motion with respect to key seat, has groove on the key seat, and brake pin projection radially is defined in the groove, but along continuous straight runs moves in groove.Adopt key seat to make the brake pin fix the spatial position, make the brake pin accurately to insert in the wheel lock groove.
As a kind of improvement of the present utility model, described brake pin is connected by spring with electrical retractor.Spring can cushion electrical retractor to the power that the brake pin produces, and avoids in brake pin moving process, and projection on the brake pin and brake pin are damaged self.
Electrical retractor can be the universal device that moves reciprocatingly by the driven by motor parts in the prior art.As by the motor driven gear rotation, have the flexible rod of toothrow again by this gear driven, when motor rotates forward or backwards, can be so that the flexible rod to-and-fro motion.
Spring in the utility model can be all kinds of elastic parts or a device in the prior art.
The electric brake mechanism that the utility model provides is provided with switch and electrical retractor, only needs to press switch button by hand, just can realize brake locking or release the lock, and is easy to operate.
Description of drawings
Fig. 1 is the utility model intelligent braking mechanism lock state schematic representation;
Fig. 2 is the utility model intelligent braking mechanism release the lock view.
Embodiment
As illustrated in fig. 1 and 2, a kind of intelligent braking mechanism, comprise switch 1, electrical retractor 2 and brake pin 4, switch 1 can be installed in any position of car, but for easy to use, be preferably mounted at car push rod left-hand seat position often contact or subconscious contact, electrical retractor 2 is connected with switch 1 by lead, and ABAP Adapter composition loop, power supply can use common batteries.
Electrical retractor 2 and brake pin 4 are connected by spring 3, brake pin 4 and spring 3 are on same straight line, brake pin 4 put with key seat 8 in, length can move relative to key seat 8 along continuous straight runs greater than the length of key seat 8, has groove on the key seat 8, brake pin 4 projection 6 radially limits in the groove, and can be in groove relative to key seat 8 along with brake pin 4 moves, stretch out outside the groove away from brake pin 4 one ends at its top, contact switch 5 contact matching that can be provided with key seat 8.
Certainly key seat 8 also can be hollow structure, and contact switch 5 is arranged on the inwall of key seat 8, and the radial protrusion of brake pin 4 is located at key seat inside, and can with contact switch 5 contact matching.
The utility model intelligent braking mechanism carries out work by following mode:
1. when pressing switch 1, connect power supply, electrical retractor 2 work, pulling spring 3, make the locking slot of brake pin separating wheel 7 and along with spring 3 moves together, when the radial protrusion 6 contact terminal switches 5 on the brake pin 4, brake pin 4 does not move, and spring 3 further stretches, because the pulling force of spring 3, make protruding 6 docking point switches 5 exert pressure, make electrical retractor 2 quit work, brake is in the release the lock state.
2. after pressing switch 1 once more, power connection, electrical retractor 2 work, pressure spring 3, the radial protrusion 6 of brake pin 4 separates with contact switch 5, and brake pin 4 inserts in the locking slot of wheels 7 near wheel one ends, and brake is in the lock state.
