Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 and 2, the wiper arm promotes structure, including preceding wiper arm 1 and back wiper arm 2, preceding wiper arm 1 rotates with back wiper arm 2 to be connected, preceding wiper arm 1 and wiper assembly 10 fixed connection, the middle part of back wiper arm 2 is equipped with fixing base 3, fixing base 3 rotates and connects electric putter 4, electric putter 4's other end fixed connection buffer 5, the other end of buffer 5 rotates with the tip of movable rod 6 to be connected, the other end of movable rod 6 is connected with preceding wiper arm 1, be equipped with the supporting seat 7 of vertical setting on the back wiper arm 2, supporting seat 7 rotates with the middle part of movable rod 6 to be connected.

Buffer 5 includes barrel 501, swing joint diaphragm 502 in the barrel 501, the below of diaphragm 502 is equipped with buffer spring 503, the top of diaphragm 502 is equipped with rubber cushion block 504, the montant 505 of the vertical setting of fixed connection on the diaphragm 502, the through-hole that montant 505 passed rubber cushion block 504 and barrel 501 top rotates with the movable rod 6 to be connected.

The bottom of back brush arm 2 is equipped with the slope pole 8 towards the slope of brush direction, the tip fixed connection extension spring 9 of slope pole 8, the other end and the preceding brush arm 1 fixed connection of extension spring 9. The supporting seat 7 and the inclined rod 8 are both arranged close to the connecting point of the front sweeping arm 1 and the rear sweeping arm 2.

When the motor sweeper carries out the operation of cleaning, electric putter 4's telescopic link stretches out, drives the activity of movable rod 6 through buffer 5, and slide bar 6 uses supporting seat 7 to rotate as rotating the strong point, and the brush arm 1 that sweeps before the drive is rotatory to ground direction, and then makes the brush can hug closely ground and clean the operation. When a road meets a bumpy road surface, the sweeper bumps and fluctuates, so that the front sweeper arm 1 shakes up and down, the joint of the movable rod 6 and the buffer 5 generates impact, the buffer spring 503 in the buffer 5 can buffer the lifting of the sweeper, and the rubber cushion block 504 in the buffer 5 can buffer the falling of the sweeper. Set up extension spring 9 on preceding brush arm 1, extension spring 9 is connected with the last down tube 8 of back brush arm 2, and the setting of extension spring 9 for preceding brush arm 1 of sweeping has a tensile power down all the time, avoids the brush to rock upwards as far as. Under the double buffering action of the tension spring 9 and the buffer spring 503, the swinging of the sweeper on a bumpy road surface is avoided as much as possible, so that the sweeper can work as closely as possible, the direct impact between the buffer 5 and the movable rod 6 is greatly reduced, and the service life is prolonged. Through buffer 5 as the transition connection spare between electric putter 4 and the movable rod 6, avoid electric putter 4 and the 6 direct contact of movable rod, when suffering jolting and heaving, avoid the rigidity between the two to strike and seriously influence life, adopt buffer 5 as transition connection spare, can absorb most impact force, can both play the guard action to electric putter 4 and movable rod 6. When the sweeping operation is not required to be executed, the telescopic rod of the electric push rod 4 retracts, and the front sweeping arm 1 is driven to lift through the movable rod 6, so that the sweeping brush is far away from the ground. When walking on a bumpy road, the tension spring 9 and the buffer 5 can still play a role in buffering.

The utility model discloses not be limited to above-mentioned embodiment, anybody should learn the structural change who makes under the teaching of the utility model, all with the utility model discloses have the same or close technical scheme, all fall into the utility model discloses an within the protection scope.
