Detailed Description

As shown in fig. 1-5, 8, 10, 12, this example can achieve the effect of absorbing the momentum of the washing robot itself.

Because a big stroke buffering of contact structure of charging includes contact installation casing 2, copper contact 3 and waist type guide way 14 charges, it has four waist type guide ways 14 to open under to from last on the contact installation casing 2, four copper contact 3 of charging are inserted respectively on four waist type guide ways 14, four copper contact 3 of charging carry out the secondary buffering through buffer structure, four copper contact 3 of charging can slide on four waist type guide ways 14 and realize the buffering, make second grade buffer structure through adopting the spring, can effectively absorb floor cleaning robot own momentum, make the automobile body and fill electric pile can steadily the butt joint, can not oppress and fill electric pile itself, the stability of the butt joint of charging has been improved, also let the better realization of butt joint procedure ability, the life-span of filling electric pile has been prolonged. Four copper contacts are arranged on the vehicle body of the ground washing robot, the four copper contacts on the ground washing robot are respectively contacted with the four charging copper contacts 3 during charging, two of the four charging copper contacts 3 are the positive and negative electrodes of a power supply, and the two are the positive and negative electrodes of a signal. After two signal contacts are contacted and conducted with the copper contact on the automobile body, a signal can be generated and fed back to the bottom controller, the bottom controller knows that the automobile body is aligned with the charging pile after obtaining the signal, the charging can be carried out, then a charging instruction is given, the charging positive and negative contacts are connected, and the robot starts to be charged.

This example can achieve the effect of achieving secondary buffering, as shown in fig. 4-5.

Because buffer structure includes one-level buffer gear and second grade buffer gear, and then realizes the secondary buffering through one-level buffer gear and second grade buffer gear.

This example can achieve the first buffering effect as shown in fig. 4-5, 8, 11.

Because one-level buffer gear includes contact guide block 4, buffer spring I6 and long cylindrical foot 17, the copper shell of charging copper contact 3 for having certain thickness, contact guide block 4 has been inserted to every charging copper contact 3 last equal interference fit, there are two long cylindrical feet 17 on the contact guide block 4, all overlap on every long cylindrical foot 17 has buffer spring I6, the robot is with four contact of charging copper contact 3 after, can carry out the buffering for the first time through buffer spring I6 on the long cylindrical foot 17.

As shown in fig. 11, this example can achieve the effect that the plastic member is effectively insulated.

Because the contact guide block 4 is a plastic piece, the plastic is acrylonitrile-butadiene-styrene plastic, and the contact guide block 4 is a plastic piece, the contact guide block can be effectively insulated, and the electricity on the charging copper contact 3 is prevented from being transmitted to a position where the electricity is not needed.

As shown in fig. 11, this example can achieve the effect of preventing the charging copper contact 3 and the contact guide 4 from coming off the contact mounting case 2 as a whole.

Since the positioning shoulder 18 is integrally formed on each contact guide block 4, the positioning shoulder 18 is located inside the contact mounting case 2, and the positioning shoulder 18 prevents the charging copper contact 3 and the contact guide block 4 from being removed from the contact mounting case 2 as a whole.

As shown in fig. 2 and 4-7, this example can achieve the effect of the first damping by the plurality of damping springs i 6.

Because one-level buffer gear still includes fixed plate 5, hole 15 is laid to set screw I10 and spring, fixed plate 5 installs the rear side at contact installation casing 2, be provided with eight springs on fixed plate 5 and lay hole 15, eight buffer spring I6's rear end pushes up respectively on eight springs lay hole 15, eight long cylindricality foot 17 is inserted respectively on eight springs lay hole 15, the inside of contact installation casing 2 is provided with six and inlays screw 13, six set screw I10 pass fixed plate 5 and threaded connection respectively on six are inlayed screw 13, fix fixed plate 5 on contact installation casing 2, fixed plate 5 keeps off the rear side at a plurality of buffer spring I6, carry out spacingly to a plurality of buffer spring I6's rear side, after a plurality of charge copper contact 3 were pressed by the floor cleaning machine people, long cylindricality foot 17 on a plurality of charge copper contact 3 and a plurality of contact guide 4 laid hole 15 and move backward relatively to the spring, and then a plurality of buffer spring I6 are compressed, carry out first buffer I through a plurality of buffer spring 6.

As shown in fig. 1-5, 8-9, this example can achieve the effect that the force of the entire robot striking the charging post is fully absorbed by the two-step spring.

Because second grade buffer gear is including charging contact subassembly mounting panel 1, buffer spring II 7, contact fixed strip 8, fixed panel beating 9, set screw II 11 and set screw III 12, the welding has contact fixed strip 8 on the contact subassembly mounting panel 1 that charges, set panel beating 9 is provided with two, two set panel beating 9 all connect on contact fixed strip 8 through a plurality of set screw III 12, all wear three set screw II 11 to the front after to on every set panel beating 9, the equal threaded connection of tip of every set screw II 11 is on contact fixed strip 8, be provided with the rectangular hole that corresponds contact installation casing 2 on the contact subassembly mounting panel 1 that charges, 2 clearance fit of contact installation casing are inserted on the rectangular hole, six set screw II 11 all pass contact installation casing 2, all the cover has buffer spring II 7 on six set screw II 11, six buffer spring II 7 all are located between corresponding set screw 9 and the contact installation casing 2, at this moment, it makes the copper contact that charges 3 toward the shrink earlier to charge after the contact touches the copper contact 3 that charges to carry out a plurality of I compression and the relative contact installation casing 2 that move to the installation casing 11 more buffer springs and carry out the grow on II relative fixed screw installation casings 11. The power that whole robot striking was filled electric pile is whole absorbed by two steps of springs like this, and the whole portable stroke grow of copper contact 3 that charges just can not be bounced by the reaction force open to the car body of floor cleaning robot, makes the butt joint more steady.

This example can achieve the effect of energizing the charging copper contact 3, as shown in fig. 4.

The binding screw 16 on the charging copper contact 3 is used to connect an external wire, thereby energizing the charging copper contact 3.

As shown in the figure 5 of the drawings,

buffer spring I6's elasticity is less than buffer spring II 7 in the design, compresses buffer spring I6 earlier and makes the copper contact 3 that charges contract back after the contact that charges touches the copper contact 3 that charges of filling electric pile at the robot, drives contact installation casing 2 again and presses to a plurality of buffer spring II 7 when buffer spring I6 compresses to certain degree elasticity grow, realizes the secondary buffering.

As shown in fig. 6, this example can achieve the effect of allowing the wires to pass through the fixing plate 5 into the inside of the contact mounting case 2 and to be connected with the plurality of charging copper contacts 3.

Because the fixing plate 5 is provided with four through holes 19, the four through holes 19 are respectively opposite to the positions of the four charging copper contacts 3, and then the four through holes 19 can supply the conducting wires to pass through the fixing plate 5, enter the contact mounting shell 2 and be connected with the plurality of charging copper contacts 3.
