Referring to fig. 1 to 3, the present embodiment provides a driving structure 1 of a sweeper, including a housing 10 of the sweeper, and a handle 20 and a driving circuit 30 respectively connected to the housing 10.

In this embodiment, the housing 10 is provided with a connecting groove 11, two first rollers 12 and two second rollers 13. Wherein the connecting slot 11 is concavely arranged at the edge position of the shell 10, and a handle 20 is rotatably connected in the connecting slot 11. Each first roller 12 is exposed on one side of the casing 10 close to the ground and is rotatably connected to the casing 10. The second rollers 13 are disposed on the same side as the first rollers 12, and each of the second rollers 13 is exposed out of the housing 10 and is rotatably connected to the housing 10. It should be noted that the first roller 12 and the second roller 13 are disposed opposite to each other and are used for assisting in moving the housing 10. In other embodiments of the present invention, the casing 10 is not limited to the embodiment provided with two second rollers 13, and the casing 10 may not be provided with the second rollers 13.

The handle 20 includes a body 21 and a toggle plate 22, wherein two pivot shafts 211 are oppositely disposed on the end of the body 21 connected to the connecting slot 11, and each pivot shaft 211 is rotatably connected to the connecting slot 11 so that the handle 20 can rotate relative to the connecting slot 11. The toggle plate 22 includes a fixing portion 221 and a toggle portion 222 integrally formed, wherein the fixing portion 221 is fixed on one of the pivot shafts 211 of the body 21, so that when the body 21 rotates in the connecting slot 11, the fixing portion 221 can rotate along with the rotation of the body 21. The toggle portion 222 is exposed on the pivot shaft 211 and disposed corresponding to a portion of the driving circuit 30, so that when the fixing portion 221 rotates with the body 21, the toggle portion 222 rotates to a position abutting against or separated from the portion of the driving circuit 30, that is, the toggle portion 222 is controlled to be connected with the portion of the driving circuit 30 in a butting manner.

In this embodiment, the driving circuit 30 includes a battery 31, a motor 32, a first switch 33, a second switch 34, a limit switch 35, a main switch 36 and a charging port 37, which are electrically connected. Wherein the battery 31, the motor 32, the limit switch 35, the main switch 36 and the charging port 37 are connected in the housing 10, and the first switch 33 and the second switch 34 are connected to the other end of the body 21 away from the housing 10. In other embodiments of the present invention, the main switch 35 and/or the charging port 37 may not be provided on the driving circuit 30.

It will be appreciated that the battery 31 is a rechargeable battery for providing electrical power to the drive circuit 30. The motor 32 is drivingly connected to an external roller via a transmission set 40, and the motor 32 is controlled to rotate in the forward or reverse direction by the first switch 33 and the second switch 34. The limit switch 35 and the toggle portion 222 can be connected in a butting manner to cut off or conduct the driving circuit 30. The main switch 36 and the charging port 37 are electrically connected to the battery 31 and partially exposed from the housing 10, respectively, the main switch 36 is used for turning on or off the driving circuit 30, and the charging port 37 is used for connecting to an external power source to charge the battery 31.

In this embodiment, the transmission set 40 includes a first gear 41, a second gear 42 and a transmission belt 43, wherein the first gear 41 is fixed on the rotating shaft of the motor 32, the second gear 42 is fixed with the external roller, the transmission belt 43 is connected to the first gear 41 and the second gear 42, and the transmission belt 43 is respectively engaged with the first gear 41 and the second gear 42 for transmitting the rotation torque of the motor 32 to the external roller to drive the external roller to rotate. In other embodiments of the present invention, the transmission set 40 may also be composed of a plurality of transmission gears, which are connected to the motor 32 and between the external rollers.

The operation of the driving mechanism 1 is roughly as follows: after the driving circuit 30 is started through the main switch 36, if the main body 21 is vertically connected to the connecting groove 11, the toggle part 222 of the toggle plate 22 is abutted (or separated) with the limit switch 35 to isolate the driving circuit 30, and at this time, the driving structure 1 is in a rest state, so that the situation that the motor 32 is started due to the fact that the first switch 33 or the second switch 34 is inadvertently contacted is avoided, and the use safety of the driving structure 1 of the sweeper is improved. If the main body 21 is rotatably connected to the connecting slot 11, the toggle portion 222 is separated from (or abutted to) the limit switch 35 along with the rotation of the main body 21 to conduct the driving circuit 30, and at this time, the driving structure 1 is in a working state, so that the first switch 33 or the second switch 34 can control the motor 32 to rotate forward or backward to drive the external roller to rotate forward or backward. It can be understood that the rotation of the external roller not only can clean the floor, but also the forward rotation or the reverse rotation of the external roller can drive the housing 10 to move forward or backward through the first roller 12 and the second roller 13, so as to achieve the function of electrically driving the housing 10 to move. If the driving mechanism 1 needs to be in the rest state, the body 21 may be vertically connected to the connecting groove 11 again.

In conclusion, the driving structure 1 of the sweeper provided by the embodiment can realize the partition of the driving circuit 30 during rest and the communication during working through the matching between the poking plate 22 and the limit switch 35, so that the use safety is improved, the operation is simple and convenient, and the practicability is high.
