Description
Technical field
The utility model relates to a kind of dust catcher collision sensing device, relates in particular to a kind of two fulcrums that utilize and exchanges the stressed dust collector collision board structure of improvement.
Background technology
Existing home-use dust catcher great majority need be by manually-operated, and it is time-consuming to require great effort.In 21st century, integrate the appearance of artificial intelligence's automatic mobile dust-collecting robot, given one in the world greatest pleasantly surprised, allowing sweeps the floor has realized automation completely.Automatic cleaner generally comprises collision detecting device, has the function of collision detection signal.Impingement plate can move backward with respect to the automatic cleaner body when running into barrier, and making automatic cleaner can perceive the place ahead has barrier, is convenient to automatic cleaner and takes to retreat or go to action.It is by the motor-driven walking of self, as when running into barrier, by sensor signal is sent to the control circuit of motor, by changing the rotating speed of left and right wheels, dust catcher is turned, and the cut-through thing continues cleaning.
Impingement plate is parts of total as the part of dust catcher, is again the indispensable element in the whole sensor-based system.When barrier had been run in dust catcher left front or right front or position, dead ahead, the action that dust catcher is taked was different; And as dust catcher in cleaning process directly and barrier bump, can damage dust catcher.So the structure of collision can directly have influence on the sensitivity of displacement transducer, the correctness of processor judgement and the runnability of dust catcher.The both sides that existing dust collector collision board has utilize the chute guide rail to be connected with the chassis, and the required restoring force in back takes place in collision provides near only two torsion springs in both sides.The advantage of this mechanism is to have sensitivity preferably, and defective is monolateral stressed situation might occur when collision occurs in the opposite side of impingement plate, and good restoring force can not be provided, and impingement plate might be stuck on dust collector upper cover; The dust collector collision board that also has then utilizes two linkages to be connected with the chassis, but has only a fixed pivot, the advantage of this structure is the stressing conditions that can be good at improving impingement plate, avoided the generation of stuck phenomenon, defective is can not provide good vertical displacement when bumping in the side, the sensitivity that influences displacement transducer all exists defective more or less, can not satisfy in the middle of the actual cleaning process various requirement to dust catcher well.
The utility model content
The purpose of this utility model is at the deficiencies in the prior art, provide a kind of two fulcrums that utilize to exchange the stressed dust collector collision board structure of improvement, the utility model can improve the stressing conditions of impingement plate well, can avoid stuck phenomenon, good sensitivity is arranged, simple in structure, low cost of manufacture.
The technical scheme that its technical problem that solves the utility model adopts is as follows: a kind of two fulcrums that utilize exchange the stressed dust collector collision board structure of improvement, and it comprises collision board body, supports pin, slide link, hinge connecting rod, straight pin, cone pin, V-arrangement back-up block, torsion spring and dust catcher chassis; Described collision board body is supported on above the chassis by 4 fulcrums, and wherein, two strong points are contacted with V-arrangement back-up block face by the v-shaped structure that supports the pin afterbody and form; Two other strong point is connected by cylinder axis above the hinge connecting rod and the cylindrical hole on the chassis and forms.
Further, described collision board body is circular-arc, and the angle of institute's envelope is for being not more than 180 degree; 4 strong points that connected are supported on collision board body on the chassis with suspending.
Further, described slide link is connected by straight pin formation cylindrical pair with the hinge connecting rod; Wherein, straight pin and slide link are interference fit, and straight pin and slide link are matched in clearance.The chain other end of bar repeatedly has cylinder axis on a cylindrical hole and the chassis to form cylindrical pair to be connected, and the center of torsion spring is in this junction.
Further, described support pin is screwed on collision board body by the semilune strip hole, and its afterbody has a v-shaped structure, and the V-arrangement back-up block on this v-shaped structure and the chassis is connected; Support and also have a circular hole on the pin.
Further, on the described support pin strip hole is arranged, cone pin connects support pin and slide link, supports between pin and the slide link and can relatively move along strip hole.
The utility model is compared with background technology, and the useful effect that has is:
1, has two convertible fulcrums, realize by supporting pin and V-arrangement back-up block.It is center of circle rotation that the collision of any side all can make collision board body center on a side fulcrum opposite with the collision origination point, effectively improved the stressing conditions on the impingement plate, prevent the one-sided stressed generation of impingement plate, also prevented to take place when impingement plate from bumping stuck phenomenon simultaneously.By the mode of a point transformation, amplified the displacement of impingement plate at vertical direction, improved the susceptibility of displacement transducer.
2, collision board body is circular-arc, and the angle of institute's envelope is 180 degree.Under the requirement that does not influence the master-plan function, the gadget that its surface allows local change of shape or can be inlaid with different materials is to increase aesthetic property.Being fixed on the chassis that collision board body suspends, the frictional force when having reduced collision board body and chassis and relatively moving improves flexibility and susceptibility that collision board body moves greatly by two fixed pivots in the connecting rod link mechanism that is connected.
3, the relation that is connected with the chassis of collision board body is not only simple in structure, and low cost of manufacture, can be good at improving the reliability and the accuracy of structure action.
