DETAILED DESCRIPTION

[0021] During the cleaning process, the industrial vacuum cleaner heads face the ground and maintain a proper distance from the ground to suck the waste and dust on the ground into the collection tube. However, the suction power of the vacuum cleaner heads is limited, and some waste adhering to the ground may be difficult to be cleaned by the industrial vacuum cleaner, which will result in the cleaning effect being less than expected.

[0022] In view of the above reasons, an embodiment of the present application provides an automatic vacuum sweeper that can peel waste off the ground and push it to the location of the vacuum head, thereby achieving a better cleaning effect.

[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] In the description of the embodiments of the present application, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "inside", "outside", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the embodiments of the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. The terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0025] An automatic vacuum sweeper provided in an embodiment of the present application includes a traveling vehicle 1, a vacuum cleaner 2, a first bracket 3, a fixing mechanism 4 and a cleaning mechanism 5, such as Figures 1 to 5 shown.

[0026] The traveling vehicle 1 can receive external traveling instructions or travel autonomously, and control the traveling speed and direction.

[0027] The vacuum cleaner 2 is installed on the traveling vehicle 1. The vacuum cleaner 2 includes a collection barrel 21, a dust suction pump 22, a dust suction pipe 23 and a dust suction head 24. The dust suction pump 22 is connected to the collection barrel 21 to form a negative pressure in the collection barrel 21. Both ends of the dust suction pipe 23 are connected to the dust suction head 24 and the collection barrel 21 respectively. The dust suction head 24 is generally facing the ground, and sucks the debris and dust on the ground into the collection barrel 21.

[0028] The first bracket 3 is connected to the rear of the traveling vehicle 1 to provide an installation position for the fixing mechanism 4 and the cleaning mechanism 5. The traveling vehicle 1 drives the fixing mechanism 4 and the cleaning mechanism 5 to move with the traveling vehicle 1 through the first bracket 3, thereby cleaning the ground and sucking the debris and dust on the ground into the collection tube 21.

[0029] The fixing mechanism 4 is mounted on the first bracket 3 and is used to fix the dust head 24 of the dust collector 2. The dust head 24 is fixed to the fixing mechanism 4 so that the dust head 24 is generally facing the ground, and the debris and dust on the ground enter the collection tube 21 through the dust head 24 and the dust pipe 23.

[0030] The cleaning mechanism 5 specifically includes a first motor 51, a first transmission assembly 52 and a cleaning wheel 53. The first transmission assembly 52 is mounted on the first bracket 3, and its input end is connected to the rotating shaft of the first motor 51. The two ends of the cleaning wheel 53 are rotatably connected to the first bracket 3, and are transmission-connected to the output end of the first transmission assembly 52, and are configured to rotate in the direction of the fixing mechanism 4 to clean the ground. When the cleaning mechanism 5 is working, the rotating shaft of the first motor 51 rotates continuously, transmitting power to the input end of the first transmission assembly 52, and the output end of the first transmission assembly 52 drives the cleaning wheel 53 to rotate to clean the debris and dust on the ground.

[0031] When the automatic vacuum sweeper provided by the embodiment of the present application performs vacuum sweeping work, the traveling vehicle 1 can travel in the space to be cleaned, and the first motor 51 transmits power to the cleaning wheel 53 through the first transmission assembly 52; the cleaning wheel 53 rotates on the bracket to clean the ground, especially the waste adhering to the ground, and the cleaning wheel 53 cleans the waste to the position of the fixing mechanism 4, and when the vacuum cleaner 2 is working, the dust head 24 sucks the waste and dust cleaned by the cleaning wheel 53 to the collection cylinder 21. Therefore, the cleaning wheel 53 of the automatic vacuum sweeper provided by the embodiment of the present application effectively peels the waste off the ground and pushes it to the position of the dust head 24, so that the automatic vacuum sweeper has a better cleaning effect, which solves the technical problem that the cleaning effect in the prior art is not as good as expected.

[0032] For example, refer to Figure 3 and Figure 4 , the cleaning wheel 53 is located in front of the moving direction of the fixing mechanism 4. When the first bracket 3 moves forward under the drive of the traveling vehicle 1, the cleaning wheel 53 first contacts the waste and dust on the ground, sweeps the waste and dust to the vicinity of the fixing mechanism 4, and the dust suction head 24 cleans the waste and dust, so that the automatic vacuum sweeper has a better cleaning effect.

[0033] In other embodiments of the present application, the cleaning wheel 53 may also be arranged at the rear of the moving direction of the fixing mechanism 4. When the first bracket 3 moves forward driven by the traveling vehicle 1, the dust collecting head 24 first cleans the waste and dust on the ground, and the waste and dust remaining on the ground are cleaned by the cleaning wheel 53 at the rear toward the fixing mechanism 4, and then the dust collecting head 24 cleans the remaining waste and dust again.

[0034] The embodiment of the present application provides a specific structure of the traveling vehicle 1. Figure 1 and Figure 2 The traveling vehicle 1 includes a traveling chassis 11 , a battery 12 , a detector 13 and a controller 14 .

[0035] The battery 12, the controller 14 and the vacuum cleaner 2 are all arranged on the top surface of the traveling chassis 11, and the detector 13 is arranged at the front end of the traveling chassis 11. The detector 13 is used to detect the road conditions and obstacles in front of the traveling vehicle 1. Exemplarily, the detector 13 can be a laser radar, a camera, etc. The controller 14 is electrically connected to the traveling chassis 11, the battery 12, the detector 13 and the vacuum cleaner 2, and is configured to supply the electric energy of the battery 12 to the traveling chassis 11, the vacuum cleaner 2 and the detector 13, and to control the traveling direction and speed of the traveling chassis 11 according to the detection result of the detector 13.

[0036] When the traveling vehicle 1 travels in a space to be cleaned, the controller 14 supplies the electric energy of the battery 12 to the traveling chassis 11, the detector 13 and the vacuum cleaner 2. The detector 13 detects the road conditions and obstacles ahead in real time, and transmits the detection results to the controller 14, which controls the traveling direction and speed of the traveling chassis 11 according to the detection results.

[0037] Continue to refer to Figure 1 and Figure 2 The traveling vehicle 1 further includes a second bracket 15 and a third bracket 16. The second bracket 15 is connected to the top surface of the traveling chassis 11, the battery 12 is installed in the second bracket 15, and the detector 13 is installed at the front end of the second bracket 15. The second bracket 15 can protect the battery 12 and prevent the battery 12 from being bumped, and at the same time provide an installation position for the detector 13.

[0038] The third bracket 16 is disposed on the top of the second bracket 15. The bottom of the collection barrel 21 of the vacuum cleaner 2 is disposed in the second bracket 15 and connected to the third bracket 16. The dust pump 22 and the controller 14 of the vacuum cleaner 2 are installed in the third bracket 16. The third bracket 16 fixes the collection barrel 21 of the vacuum cleaner 2 and protects the dust pump 22 and the controller 14.

[0039] Furthermore, the traveling vehicle 1 also includes a cleaning component 17, such as Figure 1 and Figure 2 The cleaning component 17 is connected to the front end of the traveling chassis 11 , and the middle part of the front end surface of the cleaning component 17 protrudes in a direction away from the traveling chassis 11 .

[0040] During the movement of the traveling vehicle 1, since the middle part of the front end surface of the cleaning component 17 protrudes away from the traveling chassis 11, when the cleaning component 17 encounters larger debris, the front end surface of the cleaning component 17 contacts the larger debris and pushes the larger debris in the moving direction to both sides of the traveling chassis 11, thereby preventing the larger debris from obstructing the movement of the traveling chassis 11.

[0041] For example, the specific structure of the cleaning component 17 in the embodiment of the present application is as follows: Figure 6 and Figure 7 The cleaning assembly 17 includes a connecting member 171 and two push plates 172. The two push plates 172 are connected at an obtuse angle and protrude in a direction away from the walking chassis 11. One end of the connecting member 171 is connected to at least one push plate 172, and the other end of the connecting member 171 is connected to the front end of the walking chassis 11.

[0042] like Figure 1 and Figure 2As shown, the traveling vehicle 1 in the embodiment of the present application further includes a first folding mechanism 18. The two ends of the first folding mechanism 18 are respectively connected to the cleaning component 17 and the front end of the traveling chassis 11, and are configured to fold the cleaning component 17 toward the traveling chassis 11.

[0043] The first folding mechanism 18 can fold the cleaning assembly 17 toward the traveling chassis 11 , and can also unfold the cleaning assembly 17 from the traveling chassis 11 .

[0044] When the automatic vacuum sweeper is working, the first folding mechanism 18 unfolds the cleaning assembly 17 from the traveling chassis 11, and the cleaning assembly 17 is close to the ground to push away large debris in front of the traveling vehicle 1. When the work of the automatic vacuum sweeper is completed, the first folding mechanism 18 folds the cleaning assembly 17 from the traveling chassis 11, reducing the space occupied by the automatic vacuum sweeper.

[0045] The traveling vehicle 1 in the embodiment of the present application further includes a second folding mechanism 19 . The two ends of the second folding mechanism 19 are respectively connected to the first bracket 3 and the rear end of the traveling chassis 11 , and are configured to fold the first bracket 3 toward the traveling chassis 11 .

[0046] When the automatic vacuum sweeper needs to work, the second folding mechanism 19 unfolds the first bracket 3 from the walking chassis 11, so that the vacuum head 24 and the cleaning mechanism 5 are close to the ground, and then the vacuum head 24 and the cleaning mechanism 5 clean the ground. When the work of the automatic vacuum sweeper is completed, the second folding mechanism 19 folds the first bracket 3 toward the walking chassis 11, reducing the space occupied by the automatic vacuum sweeper.

[0047] The embodiment of the present application provides a specific structure of the first folding mechanism 18. The first folding mechanism 18 can be a hydraulic cylinder, a pneumatic cylinder, an electric push rod, etc. The cleaning component 17 is hinged to the front end of the traveling chassis 11, and the two ends of the first folding mechanism 18 are respectively hinged to the front end of the traveling chassis 11 and the cleaning component 17.

[0048] The embodiment of the present application provides a specific structure of the second folding mechanism 19. Figure 1 and Figure 3 The second folding mechanism 19 includes a telescopic member 191 and a rotating member 192. The two ends of the telescopic member 191 are respectively rotatably connected to the first bracket 3 and the walking chassis 11. The rotating member 192 is arranged on the first bracket 3 and is rotatably connected to the rear end of the walking chassis 11.

[0049] The telescopic member 191 is telescopic to rotate the first bracket 3 relative to the traveling vehicle 1, thereby folding the first bracket 3 toward the traveling chassis 11 or unfolding the first bracket 3 from the traveling chassis 11. Exemplarily, the telescopic member 191 may be a hydraulic cylinder, an air cylinder, an electric push rod, or the like.

[0050] It should be noted that the automatic vacuum sweeper provided in the embodiment of the present application may include both the first folding mechanism 18 and the second folding mechanism 19 , or may include only one of the first folding mechanism 18 and the second folding mechanism 19 .

[0051] The embodiment of the present application provides a specific structure of the first transmission assembly 52, referring to Figures 3 to 5 The first transmission assembly 52 includes a first reducer 521 , a first transmission wheel 522 and a second transmission wheel 523 .

[0052] The first reducer 521 is mounted on the first bracket 3, and the input shaft of the first reducer 521 is connected to the rotating shaft of the first motor 51. The first transmission wheel 522 is mounted on the output shaft of the first reducer 521. The first motor 51 has a high output speed, and the first reducer 521 is used to reduce the power of the first motor 51 and transmit the reduced power to the first transmission wheel 522.

[0053] Exemplarily, the first reducer 521 is connected to the first bracket 3 by bolts and nuts. Of course, the first reducer 521 can also be connected to the first bracket 3 by welding, riveting, etc.

[0054] The second transmission wheel 523 is mounted on the shaft end of the cleaning wheel 53 and is in transmission connection with the first transmission wheel 522. The first transmission wheel 522 transmits power to the second transmission wheel 523, so that the second transmission wheel 523 drives the cleaning wheel 53 to rotate, thereby cleaning the ground.

[0055] Exemplarily, the first transmission wheel 522 and the second transmission wheel 523 may both be pulleys, and the belt 524 is wound around the first transmission wheel 522 and the second transmission wheel 523, so that the power of the first transmission wheel 522 is transmitted to the second transmission wheel 523 through the belt 524. Of course, the first transmission wheel 522 and the second transmission wheel 523 are not limited to pulleys, for example, the first transmission wheel 522 and the second transmission wheel 523 may also be sprockets, and chains are installed on the first transmission wheel 522 and the second transmission wheel 523, and the power of the first transmission wheel 522 is transmitted to the second transmission wheel 523 through the chains.

[0056] It should be noted that the specific structure of the first transmission assembly 52 is not limited to Figures 3 to 5 The structure shown is a limitation. In other embodiments of the present application, the first transmission assembly 52 may also be in other structural forms.

[0057] For example, the first transmission assembly 52 includes a first gear and a second gear, the first gear is installed on the rotating shaft of the first motor 51, the second gear is installed on the end of the cleaning wheel 53, the first gear is meshed with the second gear, and the number of teeth of the first gear is less than the number of teeth of the second gear.

[0058] The embodiment of the present application provides a specific structure of the fixing mechanism 4. Figure 4 As shown, the fixing mechanism 4 includes a swinging member 41 and a driving mechanism 42. The swinging member 41 is provided with a notch 4113, which is rotatably connected to the first bracket 3 and forms a first rotation axis 7. The driving mechanism 42 is mounted on the first bracket 3, and the output end of the driving mechanism 42 is connected to the swinging member 41, and is configured to drive the swinging member 41 to swing back and forth around the first rotation axis 7. The first rotation axis 7 is parallel to the ground and perpendicular to the moving direction of the first bracket 3.

[0059] When the fixing mechanism 4 is working, the output end of the driving mechanism 42 drives the swinging member 41 to swing back and forth around the first rotation axis 7, and the dust collecting head 24 mounted on the swinging member 41 swings with the swinging member 41, and the direction of the dust collecting head 24 moves back and forth in the direction perpendicular to the ground and the forward direction of the fixing mechanism 4. When encountering large-sized waste, the dust collecting head 24 mounted on the swinging member 41 can suck in the waste when swinging to an angle, thereby preventing the large-sized waste from hindering the forward movement of the automatic vacuum sweeper.

[0060] Further, continue to refer to Figure 4 The driving mechanism 42 includes a second motor 421, a second transmission assembly 422 and a connecting rod 423. The second transmission assembly 422 is mounted on the first bracket 3, the input end of the second transmission assembly 422 is connected to the rotating shaft of the second motor 421, and the output end of the second transmission assembly 422 is connected to one end of the connecting rod 423 to drive the connecting rod 423 to reciprocate in its length direction. The end of the connecting rod 423 away from the second transmission assembly 422 is rotatably connected to the swing member 41, and forms a second rotation axis 8.

[0061] The rotating shaft of the second motor 421 transmits power to the input end of the second transmission assembly 422. The second transmission assembly 422 is used to convert the rotational motion of the second motor 421 into power to drive the connecting rod 423, and drive the connecting rod 423 to reciprocate in its own length direction through the output end. When the connecting rod 423 reciprocates in its own length direction, it drives the swing member 41 to swing around the first rotation axis 7.

[0062] Further, continue to refer to Figure 3 The second transmission assembly 422 includes a second reducer 4221 and a rotating disk 4222. The second reducer 4221 is mounted on the first bracket 3, and the input shaft of the second reducer 4221 is connected to the rotating shaft of the second motor 421. The rotating disk 4222 is coaxially mounted on the output shaft of the second reducer 4221, and the end of the connecting rod 423 away from the swing member 41 is eccentrically and rotationally connected to the rotating disk 4222.

[0063] The end of the connecting rod 423 away from the swing member 41 is eccentrically and rotationally connected to the rotating disk 4222. Specifically, the connecting rod 423 and the rotating disk 4222 are rotationally connected to form a third rotation axis 9, and the third rotation axis 9 is parallel to the rotation axis of the rotating disk 4222. When the rotating disk 4222 rotates, the end of the connecting rod 423 away from the swing member 41 rotates around the third rotation axis 9 and moves in the height direction. In this way, the connecting rod 423 can drive the swing member 41 to swing around the first rotation axis 7.

[0064] Exemplarily, the second reducer 4221 is connected to the bracket by bolts and nuts. Of course, the second reducer 4221 can also be connected to the first bracket 3 by welding, riveting, etc.

[0065] The second rotation axis 8 is parallel to the first rotation axis 7. Figure 4 Of course, the second rotation axis 8 and the first rotation axis 7 can also be arranged to cross.

[0066] The swing member 41 includes a swing plate 411, a first rotating seat 412 and a second rotating seat 413. A notch 4113 is provided on one side of the swing plate 411. The first rotating seat 412 and the second rotating seat 413 are both arranged on the swing plate 411, and the first rotating seat 412 is rotatably connected to the bracket to form a first rotating axis 7, and the second rotating seat 413 is rotatably connected to the output end of the driving mechanism 42 to form a second rotating axis 8.

[0067] The driving mechanism 42 is Figure 4 In the specific structure shown, the end of the connecting rod 423 away from the transmission assembly is rotatably connected to the second rotating seat 413, and the connecting rod 423 drives the swing plate 411 to swing around the first rotation axis 7 through the second rotating seat 413, thereby causing the dust collector 24 to swing.

[0068] Exemplarily, the first rotating seat 412 and the second rotating seat 413 can be connected to the swing member 41 by bolts and nuts. Of course, the first rotating seat 412 and the second rotating seat 413 can also be connected to the swing plate 411 by welding, riveting and other connection methods.

[0069] Furthermore, if Figure 4 The swing plate 411 includes a first swing portion 4111 and a second swing portion 4112. The first swing portion 4111 is provided with a first rotating seat 412, and a first side 4111a of the first swing portion 4111 is provided with a notch 4113. The second swing portion 4112 is connected to a second side 4111b of the first swing portion 4111, and the second swing portion 4112 is provided with a second rotating seat 413. The first side 4111a and the second side 4111b are arranged facing each other.

[0070] Exemplarily, the first swing part 4111 is integrally connected with the second swing part 4112. Of course, the first swing part 4111 and the second swing part 4112 can also be welded, bonded, etc.

[0071] When the automatic cleaning and sweeping vehicle is working, the cleaning wheel 53 cleans the ground, which will cause some dust on the ground to float up, in order to prevent excessive diffusion of dust and cause air pollution. The automatic vacuum cleaning vehicle provided in the embodiment of the present application also includes a spray mechanism 6, such as Figure 1 and Figure 2 shown.

[0072] The spray mechanism 6 is disposed above the first bracket 3 and connected to the traveling vehicle 1, and is configured to spray the first bracket 3. When the automatic vacuum sweeper provided in the embodiment of the present application is working, the spray mechanism 6 sprays mist water vapor to the first bracket 3, so that the floating dust combines with the water droplets and falls down, thereby preventing dust from polluting the air.

[0073] The embodiment of the present application provides a specific structure of the spray mechanism 6. Figure 1 and Figure 2 The spray mechanism 6 includes a water tank 61, a water pump and a spray pipe 62. The input end of the water pump is connected to the inner cavity of the water tank 61, and the output end of the water pump is connected to the spray pipe 62. The water tank 61 is installed on the traveling vehicle 1, and the spray pipe 62 is arranged above the bracket and connected to the outer surface of the water tank 61.

[0074] The water pump is used to pump the water in the water tank 61 to the spray pipe 62, so that the water in the water tank 61 is sprayed out from the spray pipe 62 to form mist. Figure 1 and Figure 2 In the embodiment, the water pump is installed in the water tank 61. Of course, the water pump can also be installed outside the water tank 61.
