Description
Technical field
The utility model relates to field of mechanical technique, specifically a kind of car door limiter with check mechanism.
Background technology
The design of traditional automobile door stopper, only have the spacing of several car door opening angle, if in car door opening process occupant do not notice pedestrian outside car or vehicle close, then easily meet accident during car door opening accident, do not have active defense function.
Summary of the invention
The utility model is for overcoming the deficiencies in the prior art, a kind of car door limiter with check mechanism is provided, can utilize sensor detecting to automobile external have pedestrian or the close situation of vehicle and the signal sent, electric motor starting driving cam and leverage, the braking of clamping position limit arm, locking car door instantaneously, thus avoid the generation of accident, there is active defense function.
For achieving the above object, design a kind of car door limiter with check mechanism, comprise position limit arm assembly, it is characterized in that: one end connection bracket assembly of position limit arm assembly, the other end of position limit arm assembly connects check mechanism by housing unit; Described check mechanism comprises lever assembly, clamp, spring, position limit arm, drive motors, cam, one end of lever assembly is provided with cam, the other end linking springs of lever assembly, be positioned on the lever assembly of spring side, and the upper-lower position be positioned at inside lever assembly is connected with clamp respectively, between upper and lower two clamps, be provided with position limit arm; Described cam is coupling the driving shaft of drive motors.
Described lever assembly is upper and lower two strip bars, and the fulcrum of lever is positioned at the middle part of strip bar, and the two ends of lever are respectively actuated by cams end and spring reset end.
Described drive motors is positioned at the outside of check mechanism.
The two ends up and down of described spring connect the upper-lower position inside lever assembly respectively.
The utility model compared with the existing technology, utilize lever principle, adopt micromachine just can produce enough clamping force locking position limit arms to brake the unlatching of car door, impulse stroke is short simultaneously, system response time is short, the moment that can send at signal just produces braking action, the normal work of stop when then back-moving spring can ensure not need to brake, and can not affect the application life of stop.
Check mechanism is independent of conventional limiter portion, conventional limit function and life-span are not had any impact, and brake device structure is simple, cost is not high, reliable, working service is convenient, does not have special mounting requirement, only need when car load assembles to access motor drive signal, other mounting processs are identical with conventional stop.
Accompanying drawing explanation
Fig. 1 is the utility model structural perspective.
Fig. 2 is the utility model structural front view.
Fig. 3 is the structural representation of check mechanism.
See Fig. 2 to Fig. 3,1 is bracket component, and 2 is spacing arm component, and 3 is housing unit, and 4 is check mechanism, and 5 is drive motors, and 6 is position limit arm, and 7 is cam, and 8 is lever assembly, and 9 is clamp, and 10 is spring, and 11 is fulcrum.
Detailed description of the invention
With reference to the accompanying drawings the utility model is described further below.
As shown in Figure 1 to Figure 3, one end connection bracket assembly 1 of position limit arm assembly 2, the other end of position limit arm assembly 2 connects check mechanism 4 by housing unit 3; Described check mechanism 4 comprises lever assembly, clamp, spring, position limit arm, drive motors, cam, one end of lever assembly 8 is provided with cam 7, the other end linking springs 10 of lever assembly 8, be positioned on the lever assembly 8 of spring 10 side, and the upper-lower position be positioned at inside lever assembly 8 is connected with clamp 9 respectively, between upper and lower two clamps 9, be provided with position limit arm 6; Described cam 7 is coupling the driving shaft of drive motors 5.
Lever assembly 8 is upper and lower two strip bars, and the fulcrum 11 of lever is positioned at the middle part of strip bar, the two ends of lever are respectively actuated by cams end and spring reset end, utilize lever principle to amplify the after-applied power on clamp of drive motors driving cam, to play braking action.
Drive motors 5 is positioned at the outside of check mechanism 4.
The two ends up and down of spring 10 connect the upper-lower position inside lever assembly 8 respectively.
When drive motors 5 obtains enabling signal, drive motors 5 rotating band moving cam 7 rotates, but only need small stroke just activation lever assembly 8 clamp 9 can be clamped position limit arm 6, because compole when the signal of telecommunication and drive motors 5 starting-up response is short, lever assembly 8 and clamp 9 are parts of relative stiffness, so just brake hard can be realized, reliable function realization.
After blackout, drive motors 5 driving force disappears, lever assembly 8 resets under the effect of the spring force of spring 10, clamp 9 unclamps position limit arm 6, stop just normally works as conventional stop, check mechanism 4, independent of limit function part, does not participate in normally spacing, on normal spacing performance without any impact.
Simultaneously, position limit arm 6 surface that clamp 9 clamps is not the normal working surface of position limit arm 6 and shoe contact, the normal work and use life-span of stop can not be affected like this because of brake wear, when also stop will be moved because of brake wear, produce abnormal sound.
