Mechanism 5 is controlled, is equipped with alert mechanism in power-driven tool.
It specifically describes, power-driven tool includes motor vehicles, power vessels, power-driven plane etc., and power-driven tool can be present
Safe tape cell is set on chair 1, driver, passenger etc., when there is emergency episode, human body pair are fastened by safety belt
There are an instant impacts for safety belt 3, under the impact force action, 2 locking safety belt of seat belt retractor, in safety belt
Under protective effect human body will not inertia wash from conduct, this principle belongs to the prior art.
According to traffic method relevant regulations, when taking motor vehicles, it is currently to pass through safety that needs, which are fastened seat belts,
Whether the belt buckle 31 for being monitored safety belt with buckle mechanism 4 assembles in place, to issue associated monitoring information to lock
Tight monitor control mechanism 5, by monitor state selective actuation alert mechanism, so that personnel be reminded to wear safety belt.
In addition, also having using seat sensor, 4 cooperative monitoring of belt latch mechanism, i.e., when seat sensor monitors
When people is sat on the seat, the function triggering of belt latch mechanism 4 can be just triggered.
And generally, locking monitor control mechanism includes safety belt controller, BCM Body Control Module, that is, passes through safety belt controller
It is monitored or is monitored by BCM Body Control Module, this principle belongs to the prior art.

It specifically describes, by mechanical mode potentiometer 91 is exported outward by circuit board 9 and connector 92
Different resistance values, locking monitor control mechanism 5 judge whether safety belt stretching meets the requirements to selectivity touching by the resistance value
Activating alarm.
In addition, the design of transmission mechanism can easily be accommodated transmission ratio, it is well known that potentiometer 91 has certain effective row
Journey, and the extension elongation of safety belt 3 is longer, can not adapt to the effective travel of potentiometer 91, can adjust transmission by transmission mechanism
Than meeting the effective travel demand of potentiometer 91 so that longer extension elongation to be converted to shorter stroke.
More refinement ground explanation, the interior threshold values control being equipped with for monitoring 9 output resistance of PCB circuit board of locking monitor control mechanism 5
Device processed, threshold values controller is interior to be equipped with threshold values, the starting alarm when output resistance is less than the threshold values.
It making an exception except being preferably implemented, the monitor control mechanism of other monitoring 3 extension elongations of safety belt also can be used in this case, for example,
The setting monitoring identification marking on safety belt 3, and seat belt status detection sensor 6 can identify the monitoring identification marking, work as peace
When full band pulls out, triggering seat belt status detection sensor 6 works, and marks when the stretched certain length of safety belt to the monitoring identifies
When knowing by 6 cog region of seat belt status detection sensor, it is considered to be met stretching and required monitoring demand.
In one specific embodiment of this case, output end 8 is output shaft 81, the transmission ratio of transmission main shaft 7 and output shaft 81
Greater than 20, at least meet the transmission ratio just and can ensure that effective use of the potentiometer 91 under being limited by 2 space of seat belt retractor.
It should be noted that the rotating range of output shaft 81 is less than 360 °, i.e., the control of 91 rotating distance of potentiometer 1 circle with
Interior, optimal is 0.6 circle.
Embodiment one
As shown in Figures 2 and 3, transmission mechanism includes the first end tooth wheel 7A being arranged on transmission main shaft 7, is arranged in output shaft

It is meshed between adjacent gear.
It specifically describes, pulls safety belt 3, safety belt 3 is stretched out from seat belt retractor 2, drives peace during stretching out
Shaft 21 in full Webbing retractor 2 rotates, and transmission main shaft 7 and 21 coaxial rotating of shaft, first end tooth wheel 7A thereon pass through transmission
Transmission of the gear 10A phase end gear 8A output after transmission proportion, it is defeated that output shaft 81 drives potentiometer 91 to generate resistance value
Out.
Embodiment two
As shown in Figure 4 and Figure 5, transmission mechanism include the first end belt pulley 7B being arranged on transmission main shaft 7, setting exporting
End belt pulley 8B on axis 81 and at least one driving belt being arranged between just end belt pulley 7B and end belt pulley 8B
10B is taken turns, is equipped with driving belt 11 between arbitrary neighborhood belt pulley.Transmission ratio output is carried out by the kind of drive of belt pulley.
So as to adjust output in the effective travel of potentiometer 91.
