[0031] A cleaning robot is a type of smart household cleaning appliance that can automatically sweep, vacuum, and mop the floor. Depending on the functions of the application, there are vacuum robots, mopping robots, and robots that can mop and vacuum all in one. With the advancement of science and technology and the improvement of people's quality of life, cleaning robots have entered the lives of more and more people.
[0032] The existing tray-type mopping cleaning robot mops the surface to be cleaned by rotating the mop plate during the sweeping and vacuuming process. In order to adapt to different cleaning surfaces, such as carpets or uneven surfaces, the mopping parts of the existing tray-type mopping cleaning robot have achieved the function of rising and floating during the mopping process. The prior art discloses a utility model patent with application number 202122400172.6 and patent name "rotating telescopic floating device and automatic cleaning equipment". Its telescopic and rotating drive structure is complex, the manufacturing cost is high, and it cannot be effectively popularized.
[0033] In order to solve the above problems, this embodiment discloses a rag drive module with a compact structure. Figures 1 to 3 As shown, the driving module includes a housing 100, a rotating output shaft 200, a telescopic output shaft 300, a driving member 104 mounted on the housing 100, and a transmission assembly 105. The driving member 104 is drivingly connected to the upper end of the rotating output shaft 200 through the transmission assembly 105. An opening 108 is provided at one end of the housing 100 close to the telescopic output shaft 300. The upper end of the telescopic output shaft 300 is telescopically rotatably connected to the lower end of the rotating output shaft 200 so that the telescopic output shaft 300 can be telescoped at the opening 108.
[0034] The driving module further includes a plurality of shaft pins 101. The inner side of the opening 108 is provided with an arc groove 102 which is connected with the opening 108 and has a groove length greater than the diameter of the shaft pin 101. The groove width of the arc groove 102 gradually decreases from the end away from the opening 108 to the end close to the opening 108. The shaft pin 101 respectively contacts the telescopic output shaft 300 and the arc groove 102.
[0035] When the telescopic output shaft 300 is rotated and extended, the shaft pin 101 moves in the direction of the arc groove 102 away from the opening 108; when the telescopic output shaft 300 is rotated and retracted, the shaft pin 101 moves in the direction of the arc groove 102 close to the opening 108, and the friction between the shaft pin 101 and the arc groove 102 gradually increases until the shaft pin 101 cannot rotate, so that the telescopic output shaft 300 is retracted.
[0036] In this embodiment, the driving member 104 is preferably a motor, and the transmission assembly 105 is preferably a gear box. Their structures and working principles are all prior art and will not be described in detail here.
[0037] Specifically, the cleaning module with obstacle avoidance function of the utility model is provided with a rotating output shaft 200, a telescopic output shaft 300, a shaft pin 101 and an arc groove 102, and the rotation and extension of the telescopic output shaft 300 are realized by the friction between the telescopic output shaft 300, the shaft pin 101 and the arc groove 102; in addition, the structure of the arc groove 102 also makes the telescopic output shaft 300 not affected when rotating forward, and is retracted by the shaft pin 101 when rotating reversely, realizing the function of a clutch. Compared with the prior art, the utility model has a simple structure and low manufacturing cost, and can be effectively popularized.
[0038] Furthermore, a spring piece 103 is provided at one end of the arc groove 102 away from the opening 108. When the driving member 104 drives the telescopic output shaft 300 to rotate forward, the shaft pin 101 can be pressed against the spring piece 103 and rotate, thereby reducing the wear between the arc groove 102. In addition, an elastic member 106 is also connected between the telescopic shaft 301 and the rotating shaft 201, which can improve the stability of the telescopic output shaft 300 during telescopic operation.
[0039] Specifically, the number of the shaft pins 101 and the arc-shaped grooves 102 is not less than two, and the two arc-shaped grooves 102 are equidistantly arranged at the opening 108 to ensure the stability of the telescopic output shaft 300 during rotation.
[0040] Specifically, the rotating output shaft member 200 includes a rotating shaft 201 and a plurality of guide posts 202 arranged at the lower end of the rotating shaft 201, and the telescopic output shaft member 300 includes a telescopic shaft 301 and a guide bevel groove 302 arranged on the outside of the telescopic shaft 301 and corresponding one-to-one to the guide posts 202; when the guide post 202 contacts one end or the other end of the guide bevel groove 302, the telescopic shaft 301 rotates and telescopes along the direction of the guide bevel groove 302.
[0041] In this embodiment, the number of the guide posts 202 and the guide inclined slots 302 is three, which can ensure the stability of the telescopic shaft 301 during telescopic and rotation. Figure 4 and Figure 5 It can be seen that the guide inclined groove 302 is L-shaped. Since the lower end of the telescopic output shaft 300 is externally connected to a cleaning member such as a rag, when the driving member 104 is reversed, the telescopic shaft 301 rises along the guide inclined groove 302 under the action of the guide column 202, and finally reaches the position shown in FIG. Figure 4 when the driving member 104 is rotated forward, the telescopic shaft 301 is lowered along the guide chute 302 under the action of the guide column 202, and finally reaches the state as Figure 5 status.
[0042] Furthermore, a sensing device 107 is also provided on one side of the telescopic output shaft 300. In the present embodiment, the sensing device 107 is preferably a photosensitive signal device, which can obtain the position status of the telescopic output shaft 300 at any time.
[0043] In addition, this embodiment also discloses a robot equipped with the driving module as described above.
[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
