[0021] like Figure 1-Figure 3As shown, the utility model provides a lifting structure of a cleaning module, characterized in that it comprises: a connecting seat 10, a cleaning bracket 11, and a lifting assembly 12; the cleaning bracket 11 is located below the connecting seat 10, the lifting assembly 12 is arranged in the connecting seat 10, the lifting assembly 12 is connected to a first end of the cleaning bracket 11, the second end of the cleaning bracket 11 away from the cleaning assembly is rotatably connected to the connecting seat 10, the third end of the bottom of the cleaning bracket 11 is connected to one end of the connecting seat 10, and the lifting assembly 12 drives the first end of the cleaning bracket 11 to rise and the fourth end to fall when working, and the fourth end of the cleaning bracket 11 is connected to a cleaning module 15;

[0022] Specifically, the connecting seat 10 is also used to connect with an external structure. The lifting component 12 is fixedly arranged in one end of the connecting seat 10. The output end of the lifting component 12 is connected to the first end of the cleaning bracket 11. The second end of the cleaning bracket 11 is rotatably connected to the connecting seat 10. When the lifting component 12 is working, it will cause the first end of the cleaning bracket 11 to rise or fall. At this time, the second end of the cleaning bracket 11 will rotate relative to the connecting seat 10. The connection between the connecting seat 10 of the cleaning bracket 11 is not a direct connection, so that the cleaning bracket 11 can rotate around the point connected to the connecting seat 10. Since the connecting seat 10 is connected to the external structure, in order to enable the cleaning bracket 11 to move synchronously with the external structure, the third bottom of the cleaning bracket 11 The first end of the cleaning bracket 11 is connected to the connecting base 10, and this connection method is also an indirect connection, so that the connecting base 10 can drag the cleaning bracket 11 to move synchronously when moving and will not restrict the cleaning bracket 11 from rotating around the point connected to the connecting base 10. In this way, when the lifting component 12 moves forward, the first end of the cleaning bracket 11 will drop, prompting the fourth end of the cleaning bracket 11 to rise, driving the cleaning module 15 to rise off the ground for easy movement. When the lifting component 12 moves reversely, the first end of the cleaning bracket 11 will rise, prompting the fourth end of the cleaning bracket 11 to drop, causing the cleaning module 15 to drop and contact the ground for easy cleaning. When the connecting base 10 moves driven by the external structure, it drags the cleaning bracket 11 to move synchronously.

[0023] Further, in this embodiment, the first end of the cleaning bracket 11 is connected to a main direction wheel 116, and the fourth end of the cleaning bracket 11 is connected to an auxiliary wheel 115;

[0024] Specifically, the main direction wheel 116 is used to control the overall movement direction when cooperating with the external structure. The main direction wheel 116 is a universal wheel. The auxiliary wheel 115 is used to prevent the cleaning bracket 11 from excessively descending. When the cleaning bracket 11 descends to a certain extent, the auxiliary wheel 115 will support the cleaning bracket 11 to limit its further descent.

[0025] Further, in this embodiment, the lifting assembly 12 includes: a driving device 121, a driving chain 122, and a sprocket 123; the driving device 121 is arranged in the end of the connecting seat 10 away from the end connected to the third end of the cleaning bracket 11, the sprocket 123 is arranged in the connecting seat 10 and is spaced from the driving device 121, one end of the driving chain 122 is connected to the driving device 121, and the other end is connected to the first end of the cleaning bracket 11, and the driving chain 122 is also connected to the sprocket 123 and lifts the cleaning bracket 11 through the sprocket 123;

[0026] Specifically, the lifting assembly 12 includes: a driving device 121, which is fixedly arranged in one end of the connecting seat 10, a driving chain 122 is connected to the output end of the driving device 121, and the other end of the driving chain 122 is rotatably connected to the first end of the cleaning bracket 11, and a sprocket 123 is fixedly connected to the connecting seat 10. At the same time, the driving chain 122 half surrounds the outer side of the sprocket 123 and is transmission-connected to the sprocket 123. The position of the driving device 121 is located behind the first end of the cleaning bracket 11. When the output end of the driving device 121 retracts, the driving chain 122 is pulled backward. At this time, the driving chain 122 will pull the first end of the cleaning bracket 11 to make it rise. When the output end of the driving device 121 extends, the cleaning bracket 11 will descend by itself under its own gravity and the gravity of the main direction wheel 116.

[0027] The driving device 121 is in the form of a motor and a telescopic rod, and the extension and retraction of the telescopic rod are controlled by the forward or reverse rotation of the motor.

[0028] Furthermore, in the present embodiment, the cleaning bracket 11 comprises: a main bracket 111, a sub-bracket 113, and a connecting cross bar 112; the first end of the main bracket 111 is connected to the lifting assembly 12, the second end of the main bracket 111 is rotatably connected to the connecting seat 10 via an upper connecting swing arm 114, the connecting cross bar 112 is fixedly connected to the bottom of the main bracket 111, two sub-brackets 113 are provided, the two sub-brackets 113 are respectively fixedly provided at the two ends of the connecting cross bar 112, the same ends of the two sub-brackets 113 are respectively rotatably connected to the end of the connecting seat 10 away from the lifting assembly 12 via a lower connecting swing arm 13, the auxiliary wheel 115 is provided at the end of the sub-bracket 113 away from the connecting seat 10, and the main direction wheel 116 is provided below the end of the main bracket 111 connected to the lifting assembly 12;

[0029] Specifically, the main bracket 111 is in a "T" shape as a whole. The first end of the main bracket 111 is rotatably connected to the drive chain 122, and the second end of the main bracket 111 is rotatably connected to the upper connecting swing arm 114. The other end of the upper connecting swing arm 114 is rotatably connected to the connecting seat 10, wherein the connection position between the upper connecting swing arm 114 and the connecting seat 10 is close to the position of the sprocket 123, and the position of the connection point is in front of and behind the position of the connection point of the second end of the main bracket 111. In this case, the upper connecting swing arm 114 will press against the second end of the main bracket 111, and the drive chain 122 will lift the first section of the main bracket 111. In this state, if the driving device 121 moves in the opposite direction, the first end of the main bracket 111 will rise, and at this time the second end will be on the upper connecting swing arm 114 makes a clockwise rotation movement under the restriction of main bracket 111, so that the bottom of main bracket 111 makes a downward movement. When driving device 121 moves forward, the upward pull of driving chain 122 will drive the second end and the upper connecting swing arm 114 to make a counterclockwise movement, so that the bottom of main bracket 111 makes an upward movement; and auxiliary bracket 113 is fixedly connected to the bottom of main bracket 111 through connecting cross bar 112. In this state, since driving chain 122 is a flexible structure, in order to ensure that the movement of cleaning bracket 11 and external structure is synchronized, one end of auxiliary bracket 113 away from auxiliary wheel 115 is connected to connecting seat 10 through lower connecting swing arm 13, and auxiliary bracket 113 can rotate relative to lower connecting swing arm 13, so that main bracket 111 makes upward or downward movement.

[0030] Furthermore, in this embodiment, a stopper 14 is provided above the sprocket 123 in the connecting seat 10, and the stopper 14 is spaced apart from the sprocket 123;

[0031] Specifically, since the driving device 121 and the main bracket 111 are connected via a driving chain 122, a stopper 14 is provided above the sprocket 123 to prevent the driving chain 122 from detaching from the sprocket 123. When the driving chain 122 is connected to the sprocket 123 for transmission, the stopper can limit the driving chain 122 to the outside of the sprocket 123 to ensure stability in use.

[0032] The specific working principle is as follows: when the driving device 121 retracts (reverse) movement, the first end of the main bracket 111 rises under the pull of the driving chain 122, and when the first end continues to rise, due to the height difference, the second end drives the upper connecting swing arm 114 to rotate clockwise, resulting in a sinking movement. The sinking of the second end drives the auxiliary bracket 113 to sink, and drives the cleaning module 15 to sink and contact the ground. When sinking, due to the limitation of the lower connecting swing arm 13, the auxiliary bracket 113 is prevented from shaking back and forth; when the driving device 121 extends (forward) movement, the first end of the main bracket 111 descends under its own gravity, and pushes the second end and the upper connecting swing arm 114 to rotate counterclockwise, resulting in an upward movement until it is nearly horizontal. The rise of the second end drives the cleaning module 15 to rise and leave the ground.

[0033] In summary, the present application realizes the lifting and lowering of the cleaning module 15 by means of the driving device 121 and the driving chain 122 in combination with the upper connecting swing arm 114, so that the cleaning module 15 can avoid contact with the ground when cleaning is not needed, reduce the wear of the cleaning module 15 and avoid moving garbage or dust during movement, thereby improving the practicality of the product.

[0034] The present invention is not limited to what is described in the specification and implementation modes, and therefore, additional advantages and modifications can be easily realized by those familiar with the art. Therefore, without departing from the spirit and scope of the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details, representative devices, and illustrative examples shown and described herein.
