The purpose of this utility model is to provide a kind of battery-driven car outage handle, can freely change micro-switch.

The purpose of this utility model is to realize by following technical scheme:

A kind of battery-driven car outage handle, the micro-switch that it comprises that a main body, are located at that brake crank on this main body, are located at that stepped hole on this main body, are engaged in this stepped hole and conflicts with this brake crank.

Wherein, this brake crank is the center with the connecting portion of itself and this main body, along this center swing.

Wherein, this brake crank is provided with a spring eye, is equipped with a returning spring in this spring eye, and this returning spring one end is connected on this main body.

Wherein, this micro-switch comprises that a switch enclosure, one are located at the switch head of this switch enclosure one end, one and cover on the outer external member of this switch head and one and cover on the outer tarpaulin of this external member, this switch head is provided with first groove, this external member inside is provided with first flange with this groove fit, and this external member outside is provided with second groove, and this tarpaulin inside is provided with second flange with this second groove fit.

Wherein, this switch enclosure inside is installed with one and this switch head wire connecting, and this electric wire is provided with an iron sheet riveted spare.

Wherein, this switch enclosure other end is provided with outside thread, annular groove successively, and this outside thread is combined with a plastic nut, and recessed and this electric wire outside of this annular is with a heat-shrink tube.

Wherein, the gland of a middle perforate is pressed and is established this tarpaulin, and this gland engages with this switch enclosure.

Wherein, this brake crank is connected with a brake cable.

Positive progressive effect of the present utility model is: in its pulling brake cable brake time,, also master cock disconnects with the control motor and is idling mode, have simple in structure, handling ease, easy for installation, advantages such as operation is simple and easy, good stability.

The specific embodiment

Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.

As Fig. 1-shown in Figure 4, a kind of battery-driven car outage handle, it comprises that a main body 1, one are located at that brake crank 2 on this main body 1, one are located on this main body 1 and is located at this main body 1 hole 4 of topping bar with these brake crank 2 bonded assembly brake cable 3 and one, be combined with a switch 5 in this stepped hole 4, this brake crank 2 compresses this micro-switch 5.

This brake crank 2 is the center with the connecting bridge 21 of itself and this main body 1, along these center 21 swings.

This brake crank 2 is provided with a spring eye 22, be equipped with a returning spring 23 in this spring eye 22, and this returning spring 23 is connected on this main body 1.When this brake crank 2 is the center with the connecting bridge 21 of itself and this main body 1, during along 21 swings of this center, handle is stressed in spring 23; Behind the releasing of brake handle, handle is subjected to the lifting force of spring 23 and self-return.

Micro-switch 5 these switches comprise a switch enclosure 51, a switch head 52 that is located at these switch enclosure 51 1 ends, an external member 53 and a tarpaulin 54 that covers on outside this external member 53 that covers on outside this switch head 52, this switch head 52 is provided with first groove 521, these external member 53 inside are provided with first flange 531 that cooperates with this groove 521, and these external member 53 outsides are provided with second groove 532, these tarpaulin 54 inside are provided with second flange 541 that cooperates with this second groove 532, external member 53 can drive micro-switch 5 starts simultaneously like this, does not have stuck phenomenon and can guarantee switch 5 accurate control effects.

These switch enclosure 51 inside be installed with one with this switch head wire connecting 55, this electric wire 55 is provided with an iron sheet riveted spare 56, breaks away from micro-switch 5 in the time of can preventing to cause electric wire 55 to be subjected to external force because of electric wire 55 rack of fusion.

These switch enclosure 51 other ends are provided with outside thread 57, annular groove 58 successively, and this outside thread 57 is combined with a plastic nut 59, and plastic nut 59 can be locked micro-switch 5 and main body 1, so that change micro-switch 5.

This annular groove 57 and this electric wire 55 outsides are with a heat-shrink tube 60, play the water-tight effect, and the gland 61 of perforate in the middle of is pressed and established this tarpaulin 54, and this gland 61 engages with this switch enclosure 51, play the water-tight effect equally.

Micro-switch 5 can cooperate stepped hole 4 also to be provided with step 62, reaches the accurate in locating effect.

Electric wire 55 1 ends connect micro-switch 5 one ends and connect the motor (not shown), and during starter motor travels (shown in solid line among Fig. 2), brake crank 2 roof pressure micro-switchs 5, conducting micro-switch 5 can output signal to motor via electric wire 55 and become normal operation; When brake crank 2 is subjected to pulling force and brakes (as shown in phantom in Figure 2), its micro-switch 5 is not subjected to roof pressure, promptly is off state, control motor via electric wire 55 output signals to be idling mode, and, 3 pairs of wheel brake of brake crank 2 interlock brake cable.
