[0032] The utility model discloses a drive mechanism and a cleaning mechanism, and belongs to the technical field of automatic cleaning equipment. Figures 1-5 The utility model will be further described.

[0033] The embodiments will be described below in conjunction with the drawings to make the purpose, characteristics and effects of the utility model fully understood. Obviously, the described embodiments are only part of the embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the utility model. In addition, all the coupling / connection relations involved in the patent do not mean that the components are directly connected, but that a better coupling structure can be composed by adding or reducing coupling auxiliary components according to the specific implementation situation. The various technical features in the utility model creation can be interactively combined without mutual contradiction and conflict.

[0034] With reference to Figure 1 The utility model provides a drive mechanism 1 can apply to automatic cleaning equipment to drive cleaning mechanism 3 swing, effectively reduced the production cost of automatic cleaning equipment. Drive mechanism 1 includes stepper motor 11, driving gear 12, intermediate gear 13 and cam 14, wherein driving gear 12 is fixedly arranged at the output end of stepper motor 11, intermediate gear 13 is arranged between driving gear 12 and cam 14, intermediate gear 13 is engaged with driving gear 12, and intermediate gear 13 is connected with cam 14, when stepper motor 11 starts driving driving gear 12 to rotate, intermediate gear 13 rotates with driving gear 12, and then drives cam 14 to swing.

[0035] In specific application, cam 14 is connected to cleaning mechanism 3, when stepper motor 11 drives driving gear 12 to rotate, drives intermediate gear 13 to rotate, makes cam 14 swing, and then drives cleaning mechanism 3 to swing.

[0036] Further, in the embodiment, the intermediate gear 13 comprises coaxially arranged first and second toothed discs 131 and 132, wherein the first toothed disc 131 is engaged with the driving gear 12, and the second toothed disc 132 is engaged with the cam 14. That is, the intermediate gear 13 is arranged in the form of a double-pinion gear, and the diameter of the first toothed disc 131 is greater than that of the second toothed disc 132. Arranging the intermediate gear 13 in the form of a double-pinion gear makes the overall structure more compact and the transmission efficiency higher.

[0037] In an embodiment, the driving gear 12 and the first toothed disc 131 can be arranged as helical gears. The helical gears have good engagement performance, high coincidence degree, compact structure, and can effectively ensure the stability of transmission.

[0038] Further, the cam 14 comprises an abutting portion 142 and an engagement portion 141, wherein the engagement portion 141 is engaged with the second toothed disc 132, and the abutting portion 142 can be used to connect with the cleaning mechanism 3. The engagement of the cam 14 with the second toothed disc 132 achieves the transmission connection between the cam 14 and the stepping motor 11, and the transmission structure is stable and has high transmission efficiency.

[0039] Further, the engagement portion 141 of the cam 14 is in the form of a sector with teeth on the edge. The engagement portion 141 is arranged in the form of a sector, so that the end of the cleaning mechanism 3 connected with the cam 14 performs partial circumferential motion. In actual arrangement, the sector angle of the engagement portion 141 can be set according to the required swing angle of the cleaning mechanism 3.

[0040] Further, the driving gear 12 is fixedly arranged on the output shaft of the stepping motor 11. Specifically, the output shaft of the stepping motor 11 comprises a flat section, and the driving gear 12 is fixedly installed on the flat section. Arranging the flat section to install the driving gear 12 effectively reduces the possibility of relative sliding between the driving gear 12 and the output shaft of the stepping motor 11 during operation, thereby ensuring the stability of transmission.

[0041] The stepping motor 11 is used in cooperation with the driving gear 12 and the intermediate gear 13 to drive the cam 14. Compared with using a reduction motor as a driving source, the production cost is effectively reduced. The rotation of the stepping motor 11 is controlled by electric pulse signals, and each pulse signal makes the motor rotate by a fixed angle. Therefore, the rotation angle of the stepping motor 11 can be controlled by controlling the number of pulses, so as to control the swing angle of the cam 14, and further control the swing angle of the cleaning mechanism 3. In addition, the transmission connection between the cam 14 and the stepping motor 11 is achieved by arranging the driving gear 12 and the intermediate gear 13, which effectively increases the output torque of the driving mechanism 1 and ensures the stability and reliability of the driving mechanism 1 in driving the cleaning mechanism 3.

[0042] Based on the above-mentioned structure of the driving mechanism, the utility model also provides:

[0043] An automatic cleaning device, referring to Figures 1 to 5 The automatic cleaning device comprises the driving mechanism 1 as described above, and the driving mechanism 1 of the above mechanism is arranged in the automatic cleaning device to drive the cleaning mechanism 3 of the automatic cleaning device to swing, so that the cleaning mechanism 3 can extend out of the automatic cleaning device and clean the corners of the cleaning area, thereby reducing the cleaning dead angle of the automatic cleaning device.

[0044] The automatic cleaning device further comprises a machine body 2, a cleaning mechanism 3 and an elastic member 4. The cleaning mechanism 3 is swingably arranged in the machine body 2. The driving mechanism 1 is arranged in the machine body 2 and connected with the cleaning mechanism 3. The driving mechanism 1 is used to drive the cleaning mechanism 3 to swing, so that the cleaning mechanism 3 has a non-working position and a working position, and the cleaning mechanism 3 can swing between the non-working position and the working position. When the cleaning mechanism 3 is located at the working position, at least part of the cleaning mechanism 3 is located outside the projection area of the machine body 2 with an area of S1. When the cleaning mechanism 3 is located at the non-working position, at least part of the cleaning mechanism 3 is located outside the projection area of the machine body 2 with an area of S2, and S1 is greater than S2. Since most of the cleaning mechanism 3 is located outside the projection area of the machine body 2 at the working position, the cleaning mechanism 3 of the utility model can work in an edge-following mode to clean the edge area, such as the edge of a wall or the edge of furniture. After the edge-following mode ends, the cleaning mechanism 3 can swing to the non-working position.

[0045] Referring to Figure 2 The elastic member 4 is arranged between the machine body 2 and the cleaning mechanism 3. When the driving mechanism 1 is disconnected with the cleaning mechanism 3, the cleaning mechanism 3 swings to the working position under the elastic force of the elastic member 4. When the cleaning mechanism 3 is subjected to an external force, the cleaning mechanism 3 swings from the working position to the non-working position. When the cleaning mechanism 3 is disconnected from the external force, the cleaning mechanism 3 swings to the working position under the elastic force of the elastic member 4.

[0046] Referring to Figure 3 and Figure 4The cleaning mechanism 3 comprises a driving module 32 and a cleaning assembly 31, the driving module 32 is connected with the cleaning assembly 31 and used to drive the cleaning assembly 31 to rotate, the specific structure form and driving principle of the cleaning assembly 31 and the driving module 32 can refer to the prior art, which will not be described here. The driving module 32 is swingably arranged on the machine body 2, so that the cleaning assembly 31 has a non-working position and a working position, and the cleaning assembly 31 can move between the non-working position and the working position. When the cleaning assembly 31 is located at the working position, at least part of the edge of the cleaning assembly 31 is located outside the maximum edge of the machine body 2, so that the cleaning range of the cleaning assembly 31 can cover at least the position outside the widest position of the machine body 2 in the orthographic projection on the working surface, thereby increasing the cleaning range of the cleaning mechanism 3 and reducing the cleaning dead angle.

[0047] With reference to Figure 4 The driving mechanism 1 is arranged on the machine body 2, specifically, the stepping motor 11 is fixedly arranged on the machine body 2, the machine body 2 is provided with a rotating shaft 23, the cam 14 is rotationally connected to the rotating shaft 23, the machine body 2 is further provided with a gear shaft 24, and the intermediate gear 13 is rotationally installed on the gear shaft 24. The rotating shaft 23 and the gear shaft 24 are arranged, which is beneficial to guarantee the stability of the rotation connection between the cam 14, the intermediate gear 13 and the machine body 2.

[0048] The driving mechanism 1 can drive the cleaning mechanism 3 to extrude the elastic member 4 to deform and drive the cleaning mechanism 3 to swing from the working position to the non-working position. When edge cleaning is needed, the driving mechanism 1 is separated from the cleaning mechanism 3, at this time, the cleaning mechanism 3 moves to the working position under the elastic action of the elastic member 4 to clean the edge area. When the cleaning mechanism 3 encounters an obstacle, under the obstruction of the obstacle, the cleaning mechanism 3 is extruded and swings towards the non-working position to overcome the obstacle, at this time, the elastic member 4 deforms elastically; after the cleaning mechanism 3 overcomes the obstacle, the cleaning mechanism 3 swings to the working position under the elastic force of the elastic member 4 and continues to work in the edge mode.

[0049] With reference to Figure 1 And Figure 4Further, the cleaning mechanism 3 is provided with a boss 33 on one side, and the driving mechanism 1 can push the boss 33 to make the cleaning mechanism 3 swing towards the non-working position. Specifically, in the process of driving the cam 14 to rotate in the forward direction by the stepping motor 11, the abutting portion 142 on the cam 14 abuts against the boss 33 to push the cleaning mechanism 3 to swing towards the non-working position; when it is needed to separate the driving mechanism 1 from the cleaning mechanism 3, the stepping motor 11 is controlled to rotate the cam 14 in the opposite direction to make the cam 14 disengage from the boss 33. In this embodiment, the cam 14 is driven by the stepping motor 11 to make the abutting portion 142 disengage from the boss 33, at which time the cleaning mechanism 3 swings towards the working position under the elastic force of the elastic member 4. In actual arrangement, the boss 33 can be arranged on the driving module 32 or on the cleaning assembly 31, and the producer can design according to actual needs, which is not limited herein. In addition, the rotation of the cam 14 on the machine body 2 can be regarded as a circular motion, and the cam 14 and the machine body 2 are rotationally connected at the center of the circle, and the end of the cam 14 connected with the cleaning mechanism 3 is the radius of the circle, and the driving mechanism 1 drives the cleaning mechanism 3 to make a circular motion.

[0050] Further, the machine body 2 is provided with a limiting block 21, which is used to limit the swing range of the cleaning mechanism 3. When the cleaning mechanism 3 swings to the non-working position, the cam 14 abuts against the limiting block 21, the limiting block 21 blocks the cam 14 to limit the swing of the cam 14, and the driving mechanism 1 makes the cam 14 keep abutting against the limiting block 21, thereby realizing the working state of the cleaning mechanism 3 kept in the non-working position.

[0051] Further, when the cleaning mechanism 3 is in the non-working position, the boss 33 is tangent to the circular track of the abutting portion 142, that is, when the cleaning module is in the non-working position, the force of the cleaning module on the cam 14 is along the abutting portion 142 towards the center of the circular motion of the cam 14, that is, at this time, the cleaning module has no tangential force on the cam 14. Circular track, so the arrangement can effectively reduce the circumferential force of the cleaning mechanism 3 on the driving mechanism 1 when kept in the non-working position, so as to reduce the damage to the driving mechanism 1, and is beneficial to prolong the service life of the driving mechanism 1.

[0052] Further, the machine body 2 is provided with a positioning column 22 fixedly connected with the machine body 2, and the cam 14 is provided with a positioning groove 143 on the side facing the positioning column 22. When the cleaning mechanism 3 swings to the working position, the positioning column 22 is clamped into the positioning groove 143, and the positioning column 22 cooperates with the positioning groove 143 to limit the swing range of the cam 14, thereby limiting the swing range of the cleaning mechanism 3. In actual arrangement, the position of the positioning column 22 can be arranged according to needs, thereby controlling the range of the cleaning mechanism 3 swinging out of the machine body 2 in the working position.

[0053] Further, the elastic member 4 is a drive spring, one end of which is connected to the machine body 2 and the other end of which is connected to the cleaning module. Specifically, in the embodiment, the machine body 2 is fixedly connected with a mounting column 25, and the cleaning mechanism 3 is fixedly connected with a connecting column 34, one end of the drive spring is detachably fixed to the connecting column 34, and the other end is detachably fixed to the mounting column 25. The connecting column 34 can be arranged on the cleaning mechanism 3 or on the drive module 32, as long as the above functions can be achieved, and is not limited herein. In addition, the elastic member 4 can also be a torsion spring or other elastic structure, as long as the above functions can be achieved, and the structure of the elastic member 4 is not limited herein.
