[0032] Please refer to Figures 1 to 8 The utility model discloses a kind of locking mechanism for scrubber base, including a scrubber body 1 and a base 2 for accommodating scrubber body 1, further include a wake-up component 3 being arranged on the scrubber body 1 and the base 2, and a fixed component 4 being arranged on the base 2, the fixed component 4 includes a drive motor 41 being arranged in base 2, a drive gear 42 being arranged on the output shaft of drive motor 41, a limit guide plate 43 being arranged in the base 2 and being above the drive motor 41, a rotating drive plate 44 being engaged on the drive gear 42 and rotating on the limit guide plate 43, clamping plate 45 being arranged in the two sides of the base 2 respectively and being connected to rotating drive plate 44, fixed column 451 extending towards the direction of scrubber body 1 is formed on the clamping plate 45, fixed groove 11 for fixed column 451 is formed on the two sides of the scrubber body 1 respectively.

[0033] When user wants to place scrubber body 1 into base 2, only need to push scrubber body 1 into base 2, wake-up component 3 senses the placement of scrubber body 1, and then controls drive motor 41 in it to start, drive gear 42 arranged on it drives rotating drive plate 44 engaged on it to rotate on limit guide plate 43, so that two groups of clamping plate 45 connected to rotating drive plate 44 are tightened towards the direction of scrubber body 1 under the driving of rotating drive plate 44, and fixed column 451 on it is placed into fixed groove 11, and scrubber body 1 cannot be separated from base 2 without external force, so as to effectively ensure that base 2 performs cleaning, charging and other actions on scrubber body 1, with high locking efficiency and accuracy, high degree of automation, simple structure, convenient for daily use, and effectively improve the use experience.

[0034] For the specific structure of rotating drive plate 44, such as Figures 5 to 7As shown, the lower end of the rotating driving plate 44 is formed with a driven gear 441 engaged with the driving gear 42, and the two sides of the rotating driving plate 44 are formed with driving columns 442 extending upwardly through the clamping plate 45. The driven gear 441 is engaged with the driving gear 42, so that the driving motor 41 drives the rotating driving plate 44 to rotate on the limiting guide plate 43, and the driving columns 442 pass through the clamping plate 45, so that the rotating driving plate 44 drives the clamping plate 45 to shrink towards the scrubber body 1, thereby clamping the scrubber body 1 and achieving the purpose of locking the scrubber body 1. The whole process is simple and convenient, without the need for manpower, and is beneficial to the cooperation between parts.

[0035] Preferably, as shown in the drawings, Figure 7 As shown, the diameter of the driven gear 441 is greater than that of the driving gear 42.

[0039] Preferably, as shown in Figures 5 to 7 As shown, the limiting guide plate 43 is formed with at least one clamping limiting plate 433 extending upward to limit the clamping plate 45. The clamping limiting plate 433 is arranged on the side of the clamping plate 45, and the number and position thereof can be set according to the structure of the clamping plate 45 and the movement trajectory thereof, so in this embodiment, no specific limitation is made. By arranging the clamping limiting plate 433 on the limiting guide plate 43, the clamping plate 45 is guided by the clamping limiting plate 433 during movement, thereby limiting and guiding the clamping plate 45, making the clamping plate 45 move more easily and accurately, and effectively improving the locking efficiency of the locking mechanism.

[0040] Preferably, as shown in Figures 5 to 7 As shown, the limiting guide plate 43 is formed with at least one clamping limiting plate 433 extending upward to limit the clamping plate 45. The clamping limiting plate 433 is arranged on the side of the clamping plate 45, and the number and position thereof can be set according to the structure of the clamping plate 45 and the movement trajectory thereof, so in this embodiment, no specific limitation is made. By arranging the clamping limiting plate 433 on the limiting guide plate 43, the clamping plate 45 is guided by the clamping limiting plate 433 during movement, thereby limiting and guiding the clamping plate 45, making the clamping plate 45 move more easily and accurately, and effectively improving the locking efficiency of the locking mechanism.

[0041] For the specific structure of the wake-up assembly 3, as shown in Figures 4 to 8 The wake-up assembly 3 includes at least one Hall element 31 arranged in the base 2, and at least one magnet 32 arranged in the bottom of the scrubber body 1. When the scrubber body 1 is placed in the base 2, the Hall element 31 on the base 2 detects the proximity of the magnet 32, thereby triggering the fixed mechanism in the base 2 to lock the scrubber body 1. The entire process is highly automated and does not require human intervention. The cooperation between the Hall element and the magnet 32 is accurate, effectively improving the locking efficiency of the locking mechanism.

[0042] In order to make the scrubber body 1 more easily placed in the base 2, as shown in Figure 1 And Figure 2 The front end of the base 2 forms a push slope 21, and the front end is provided with a slope to facilitate the push of the scrubber body 1.
