Description

Prevent the mechanism of sweeper sharp impacts

Technical field

The utility model relates to the technical field of sweeper, in particular to a kind of mechanism for preventing sweeper sharp impacts.

Background technique

Traditional intelligent sweeping machine may touch barrier, directly when machine advances to avoid continuing knocking down Object and be easily damaged sweeper, machine is almost assembled with the mechanism for preventing sharp impacts along the front end of its direction of motion.However, It prevents the mechanism of sharp impacts to be usually ebonite as body, the inside is touched at present and common one or two of electronics touching switch touching is installed Hair reaction.When machine advances, once front end ebonite body encounters barrier, the touching switch that the inside connects will be touched, machine is made Wheel stopping is advanced in the direction, is gone down so that machine be avoided to move on collision.Prevent sweeper from acutely touching due to front end As a whole using ebonite part, quality and motional inertia are big for the mechanism hit, and touching switch needs biggish impact force It can work, so that the reaction sensitivity of the mechanism is poor, and biggish impact force is easily damaged machine, and can be indoor object Collide to obtain grogginess.

Utility model content

In view of the problems of the existing technology, the main purpose of the utility model, which is to provide one kind, prevents sweeper from acutely touching The mechanism hit, it is intended to which reaction sensitivity when preventing the mechanism of sharp impacts from colliding barrier for solving existing sweeper low is asked Topic.

To achieve the above object, the utility model proposes the mechanism for preventing sweeper sharp impacts, comprising: elastic collision The outside of sweeper front end is arranged in body, the elastic collision collision body, and the inner sidewall of the elastic collision collision body is equipped with elastic switch plate, If the elastic switch plate is equipped with dry contact.The inner sidewall of the elastic switch plate is equipped with projectile body, sets on the projectile body Have and is inserted into the through-hole with several one-to-one through-holes in contact, each contact, the inner sidewall of the projectile body It is arranged on the circuit board of sweeper front end.The circuit board is equipped with contact portion corresponding with each through-hole, and several The contact is connect with the circuit board by signal wire.

Preferably, the elastic collision collision body is fabricated by soft rubber material.

Preferably, the elastic switch plate is fabricated by silica gel.

Preferably, the projectile body is recovery sponge.

Compared with prior art, the machine of sweeper sharp impacts is prevented when the utility model has the beneficial effects that: colliding Structure is elastic collision, and prevents the reaction sensitivity of the mechanism of sweeper sharp impacts high, can prevent sweeper from occurring violent Collision, extends the service life of sweeper.

Detailed description of the invention

In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor Under, the structure that can also be shown according to these attached drawings obtains other attached drawings.

Fig. 1 is the structural schematic diagram for one embodiment of mechanism that the utility model prevents sweeper sharp impacts；

Fig. 2 is the explosive view for one embodiment of mechanism that the utility model prevents sweeper sharp impacts；

The utility model aim is realized, the embodiments will be further described with reference to the accompanying drawings for functional characteristics and advantage.

Specific embodiment

The utility model proposes a kind of mechanisms for preventing sweeper sharp impacts.

Referring to Fig.1-2, Fig. 1 is the structural representation for one embodiment of mechanism that the utility model prevents sweeper sharp impacts Figure, Fig. 2 are the explosive view for one embodiment of mechanism that the utility model prevents sweeper sharp impacts.

As shown in Figure 1, this prevents the mechanism of sweeper sharp impacts, comprising: elastic collision in the utility model embodiment Collision body 200, the outside of 100 front end of sweeper is arranged in elastic collision collision body 200, when sweeper 100 and barrier collide, elastic collision Collision body 200 is directly collided with barrier.The inner sidewall of elastic collision collision body 200 is equipped with elastic switch plate 300, elastic switch plate 300 If being equipped with dry contact 310.When machine collides object, the contact 310 with position of collision of objects is under the action of impact force Collision alarm is connected.The inner sidewall of elastic switch plate 300 is equipped with projectile body 400, if projectile body 400 is equipped with and dry contact 310 one-to-one through-holes 410, each contact 310 are inserted into through-hole 410, and the inner sidewall of projectile body 400 is arranged in sweeper On the circuit board 500 of 100 front ends.Circuit board 500 is equipped with contact portion corresponding with each through-hole 410, and if dry contact 310 it is equal It is connect with circuit board 500 by signal wire.

The working principle of technical solutions of the utility model: when 100 a direction advance work of sweeper, sweeper is prevented When the mechanism of sharp impacts collides barrier, under the action of impact force, elastic collision collision body 200, elastic switch plate 300 and return Body 400 can be locally deformed in position of collision, so that the contact 310 of position of collision connects with the contact portion on circuit board 500 Touching, so that collision alarm is connected, sweeper 100 stops moving in the direction after receiving collision alarm, and then avoids Sweeper 100 continues to collide.After sweeper 100, which is detached from, to be collided, projectile body 400 restores to the original state, in the work of 400 elastic force of projectile body Under, elastic collision collision body 200 and elastic switch plate 300 also restore to the original state.

Preferably, in the present embodiment, the elastic collision collision body 200 is fabricated by soft rubber material.

Preferably, in the present embodiment, the elastic switch plate 300 is fabricated by silica gel.

Preferably, in the present embodiment, the projectile body 400 is recovery sponge.

Compared with prior art, the machine of sweeper sharp impacts is prevented when the utility model has the beneficial effects that: colliding Structure is elastic collision, and prevents the reaction sensitivity of the mechanism of sweeper sharp impacts high, can prevent sweeper 100 from play occurs Strong collision extends the service life of sweeper 100.

The above is only the preferred embodiment of the present invention, and therefore it does not limit the scope of the patent of the utility model, Under all utility models in the utility model are conceived, equivalent structure made based on the specification and figures of the utility model Transformation, or directly/be used in other related technical areas indirectly and be included in the scope of patent protection of the utility model.
