Abstract
The utility model discloses an intelligent brake mechanism, including inductive switch, electric telescopic device and brake round pin, inductive 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 can initiatively guarantee automobile body safety.
Description
Technical field
The utility model relates to a kind of braking mechanism.
Background technology
The braking mechanism of existing perambulator generally comprises pedal, Transmission, brake pin and is provided with the wheel of lock slots, 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 lock slots on the wheel, be provided with Transmission rotationally on the wheel joint, be provided with driver train between brake handle and the Transmission, be the brake pin plug helix that has at least two blind holes on the circumferencial direction in the center of circle with the center of rotation of Transmission on the Transmission, brake pin plug helix has at the bottom of the brake pin plug helix, at the bottom of this brake pin plug helix is bevelled, be the spline pin plug helix that also has a plurality of blind holes on the circumferencial direction in the center of circle with the center of rotation of Transmission on the Transmission, spline pin plug helix has at the bottom of the spline pin plug helix, at the bottom of this spline pin plug helix is bevelled, is provided with a spline pin axially slidably on the wheel joint.This braking mechanism have only the people for trample brake the time, just can realize braking, stayed potential safety hazard.
Summary of the invention
The utility model provides a kind of active to guarantee the intelligent braking mechanism of safety.
A kind of intelligent braking mechanism, comprise inductive switch, electrical retractor and brake pin, inductive 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 locus, 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 fexible unit that moves reciprocatingly by the driven by motor parts in the prior art.As by the motor driven gear rotation, have the expansion link of toothrow again by this gear driven, when motor rotates forward or backwards, can be so that the expansion link crank motion.The spring that uses in the utility model can be all kinds of elastic parts or a device in the prior art.
The intelligent braking mechanism that the utility model provides is provided with inductive switch and electrical retractor, and under the situation of unattended car, car can automatically lock, and human body touches the car body inductive switch, and brake is release the lock automatically, has eliminated potential safety hazard.
Description of drawings
Fig. 1 is the utility model intelligent braking mechanism lock-out state scheme drawing
Fig. 2 is the utility model intelligent braking mechanism release the lock view
The specific embodiment
As illustrated in fig. 1 and 2, a kind of intelligent braking mechanism, comprise inductive switch 1, electrical retractor 2 and brake pin 4, inductive switch 1 can be installed in any position of car, but for easy to use, is preferably mounted at car push rod left-hand seat position often contact or subconscious contact, inductive switch 1 just can be opened when staff presses down naturally, electrical retractor 2 is connected with inductive switch 1 by lead, and external source composition loop, and power supply can use common batteries.
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 subordinate pressure sensitivity inductive switch 1, energized, electrical retractor 2 work, pulling spring 3, make the lock slots 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 hand leaves inductive switch 1, power connection, electrical retractor 2 work, compression spring 3, the radial protrusion 6 of brake pin 4 separates with contact switch 5, and brake pin 4 inserts in the lock slots of wheels 7 near wheel one ends, and brake is in the lock state.
Claims (3)
1. intelligent braking mechanism, it is characterized in that: comprise inductive switch (1), electrical retractor (2) and brake pin (4), inductive switch (1) is connected by lead with electrical retractor (2), brake pin (4) one ends link to each other with electrical retractor (2), the other end matches with wheel (1) lock slots, the brake pin radially is provided with projection (6), projection (6) and contact switch (5) contact matching.
2. intelligent braking according to claim 1 mechanism, it is characterized in that: described brake pin (4) places in the key seat (8), brake pin (4) can be done horizontal motion with respect to key seat (8), key seat has groove on (8), brake pin (8) projection (4) radially is defined in the groove, but along continuous straight runs moves in groove.
3. intelligent braking according to claim 1 mechanism, it is characterized in that: described brake pin (4) is connected by spring (3) with electrical retractor (2).
