Detailed Implementation

[0034] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0035] This invention proposes a replacement mechanism 100, which can automatically replace the filter in the dust collection box of a road sweeper, reducing the difficulty of replacement and improving operating efficiency.

[0036] Reference Figures 1 to 8 According to the replacement mechanism 100 in this embodiment of the invention, the replacement mechanism 100 is used for replacing the filter element of the sweeper. Specifically, the sweeper can clean the road surface and, during the cleaning operation, sucks the dust from the road surface into the dust collection box of the sweeper. The airflow is filtered by the filter element in the dust collection box. As the operation time increases, a large amount of dust can accumulate in the filter element in the dust collection box. At this time, it is necessary to replace the filter element in the dust collection box with a new one through the replacement mechanism 100 so that the sweeper can continue to operate. In practical applications, the sweeper can replace the filter element at a fixed location, and the replacement mechanism 100 can be fixedly set at that location for convenient fixed-point replacement by the sweeper.

[0037] The replacement mechanism 100 may include a frame 10, a drive assembly 20, and a gripping assembly 30.

[0038] The frame 10 has a storage area 14 for storing filter elements, which is used to store replaced filter elements or clean filter elements. The drive assembly 20 is connected to the frame 10, and the gripping assembly 30 is connected to the drive assembly 20. The drive assembly 20 can drive the gripping assembly 30 to move on the frame 10. The gripping assembly 30 has a first position and a second position on the frame 10, that is, the drive assembly 20 drives the gripping assembly 30 to move between the first position and the second position. In the first position, the gripping assembly 30 can grip and place filter elements on the sweeper. In the second position, the gripping assembly 30 can grip and place filter elements in the storage area 14. In this way, the filter elements in the dust collection box of the sweeper can be automatically replaced by the replacement mechanism 100. Compared with the related technology, which requires manual replacement of filter elements in the sweeper, the replacement difficulty can be reduced and the operation efficiency can be improved.

[0039] Specifically, when the sweeper needs to replace the filter, the sweeper can be driven to the replacement mechanism 100 with the side of the sweeper equipped with the dust collection box facing the replacement mechanism 100. Then, the replacement channel of the dust collection box can be opened, allowing the replacement mechanism 100 to replace the filter through the replacement channel. During this process, the drive assembly 20 first drives the gripping assembly 30 to move to the first position, at which point the gripping assembly 30 can grip the filter on the sweeper. Then, the drive assembly 20 drives the gripping assembly 30 to move from the first position to the second position, allowing the gripping assembly 30 to place the filter removed from the sweeper into the storage area 14 and to grip clean filters in the storage area 14. Then, under the action of the drive assembly 20, the gripping assembly 30 can move from the second position to the first position, allowing the gripping assembly 30 to place clean filters on the sweeper. In this way, the replacement of the filter on the sweeper can be achieved through the aforementioned steps.

[0040] Therefore, according to the replacement mechanism 100 in the embodiment of the present invention, the drive component 20 can drive the gripping component 30 to automatically replace the filter in the dust collection box of the sweeper, thereby reducing the difficulty of replacement and improving the work efficiency.

[0041] Reference Figures 1 to 8 In some embodiments of the present invention, the gripping component 30 may include a base 31 and a gripping member 32. In a first state, the gripping member 32 extends forward relative to the base 31, and in a second state, the gripping member 32 retracts backward relative to the base 31. This facilitates the replacement of the filter element by the gripping component 30 and improves the working efficiency of the gripping component 30.

[0042] In detail, the base 31 is adapted to place the filter element. The gripping member 32 extends forward relative to the base 31, driving the filter element to leave the base 31 or gripping it forward. The gripping member 32 retracts backward relative to the base 31, driving the filter element to be placed on the base 31 for easy replacement. More specifically, when it is necessary to grip the filter element, the gripping member 32 can extend forward relative to the base 31 to grip the filter element. When it is necessary to place the filter element, the gripping member 32... 2 can extend forward relative to the base 31 to drive the filter element away from the base 31; when the filter element needs to be transferred, after the gripper 32 grips the filter element, it can retract backward relative to the base 31 to drive the filter element into the base 31, so that the filter element is placed on the base 31, which facilitates the drive assembly 20 to drive the gripper assembly 30 to move between the first position and the second position to realize the transfer of the filter element; in short, the working efficiency of the gripper assembly 30 can be improved by the cooperation of the gripper 32 and the base 31.

[0043] Furthermore, referring to Figure 2 In some embodiments of the present invention, the base 31 is provided with a first slide rail 311 and a second slide rail that are opposite each other in the left-right direction. The first slide rail 311 and the second slide rail extend in the front-back direction. In a second state, the gripping member 32 is adapted to drive the filter element to slide backward into the first slide rail 311 and the second slide rail. In a first state, the gripping member 32 is adapted to drive the filter element to slide forward out of the first slide rail 311 and the second slide rail. This makes it convenient for the gripping component 30 to replace the filter element and improves the working efficiency of the gripping component 30.

[0044] The filter element may be equipped with a positioning structure. The gripper 32 cooperates with the positioning structure on the filter element to grip the filter element. When it is necessary to remove the filter element from the sweeper, it can be switched to the first state, that is, the gripper 32 extends forward relative to the base 31 and grips the filter element. Then it can be switched to the second state, that is, the gripper 32 retracts backward relative to the base 31. During this process, the positioning structure of the filter element can slide backward into the first slide rail 311 and the second slide rail under the drive of the gripper 32 to place the filter element on the base 31. Then, under the drive of the drive assembly 20, the gripper assembly 30 can move from the first position to the second position and then switch back to the first state, that is, the gripper 32 can extend forward relative to the base 31 to drive the filter element on the base 31 to slide forward out of the first slide rail 311 and the second slide rail, thereby placing the filter element into the storage area 14 of the frame 10.

[0045] Subsequently, when it is necessary to replace the filter on the sweeper, it can be switched to the first state, that is, the gripper 32 extends forward relative to the base 31 and grips the filter. Then it can be switched to the second state, that is, the gripper 32 retracts backward relative to the base 31. During this process, the positioning structure of the filter can slide backward into the first slide rail 311 and the second slide rail under the drive of the gripper 32, so as to place the filter on the base 31. Then, under the drive of the drive assembly 20, the gripper assembly 30 can move from the second position to the first position, and then it can be switched to the first state, that is, the gripper 32 can extend forward relative to the base 31, so as to drive the filter on the base 31 to slide forward out of the first slide rail 311 and the second slide rail, thereby placing the filter into the dust collection box of the sweeper.

[0046] In addition, the first slide rail 311 and the second slide rail are arranged opposite each other in the left and right direction, which makes it easy for the filter element to slide in and out stably; and when the gripping component 30 moves between the first position and the second position, the filter element can be stably placed in the first slide rail 311 and the second slide rail, which makes it easy for the sweeper to replace the filter element.

[0047] Furthermore, in some specific examples, the gripper 32 may include a drive unit and a gripping unit. The drive unit is disposed on the gripping unit and drives the gripping unit to move in the front-back direction relative to the base 31. More specifically, the base 31 may be provided with a rack extending in the front-back direction. The drive unit may include a motor and a transmission gear. The output shaft of the motor is fixedly connected to the transmission gear, that is, the motor can drive the transmission gear to rotate, and the transmission gear can mesh with the rack on the base 31. In this way, when the motor is working, the gripping unit can be driven to move in the front-back direction relative to the base 31 through the transmission meshing of the transmission gear and the rack. Additionally, the gripping part may include a driving element and a latch. The driving element may be connected to the latch to drive the latch to move in the vertical direction. The latch has a positioning groove with the opening facing downward. When gripping the filter element, the driving element may drive the latch to move downward, so that the positioning structure of the filter element can be embedded in the positioning groove of the latch. Subsequently, the motor may drive the transmission gear to rotate and drive the meshing rack, so that the gripping part moves backward relative to the seat 31, so as to drive the filter element to slide into the first slide rail 311 and the second slide rail. When placing the filter element, the motor may drive the transmission gear to rotate and drive the meshing rack, so that the gripping part moves forward relative to the seat 31, so as to drive the filter element to slide out of the first slide rail 311 and the second slide rail. Subsequently, the driving element may drive the latch to move upward.

[0048] Secondly, a sensor may be provided on the gripper 32 to sense whether the gripper 32 has gripped the filter element, so as to improve the working accuracy of the gripper 32.

[0049] Reference Figure 1 , Figures 3 to 8In some embodiments of the present invention, the front side of the frame 10 has a first opening 13. In the first position, the gripping component 30 is located behind the first opening 13, and in the first state, the gripping member 32 is driven to extend forward out of the first opening 13. In this way, the filter on the sweeper can be easily replaced through the first opening 13.

[0050] In detail, in conjunction with the foregoing embodiments, when it is necessary to replace the filter on the sweeper, the sweeper can be moved to the side of the replacement mechanism 100, and the dust collection box on the sweeper needs to be aligned with the first opening 13, and the replacement channel on the dust collection box needs to be opened. Then, the drive assembly 20 can move the gripping assembly 30 to the first position. At this time, the gripping assembly 30 is located behind the first opening 13 and switches to the first state, that is, the gripping member 32 can extend forward relative to the base 31 to grip the filter on the sweeper, or the gripping member 32 can extend forward relative to the base 31 to drive the filter on the base 31 to slide out of the first slide rail 311 and the second slide rail, thereby placing the filter on the sweeper. Therefore, the first opening 13 facilitates the passage of the gripping member 32, thereby facilitating the gripping member 32 to grip and place the filter on the sweeper, improving the replacement efficiency.

[0051] Reference Figures 3 to 8 In some embodiments of the present invention, the storage area 14 has a second opening 141 on the rear side. In a second position, the gripping component 30 is located behind the second opening 141 and drives the gripping member 32 to extend forward into the storage area 14 in a first state. In this way, the filter on the sweeper can be easily replaced through the second opening 141.

[0052] In detail, in conjunction with the foregoing embodiments, when it is necessary to replace the filter element on the sweeper, after the gripping component 30 grips the filter element, it can move from the first position to the second position under the driving action of the driving component 20. At this time, the gripping component 30 can be located behind the second opening 141 and switch to the first state, that is, the gripping member 32 can extend forward relative to the base 31 to grip the filter element in the storage area 14, or the gripping member 32 can extend forward relative to the base 31 to drive the filter element on the base 31 to slide out of the first slide rail 311 and the second slide rail, thereby placing the filter element in the storage area 14. Therefore, the second opening 141 facilitates the passage of the gripping member 32, thereby facilitating the gripping member 32 to grip and place the filter element in the storage area 14 and improving the replacement efficiency.

[0053] In addition, in conjunction with the aforementioned embodiments, a first opening 13 is provided on the front side of the frame 10. The dust collection box of the sweeper can be located on the front side of the first opening 13, while the gripping component 30 can be located on the rear side of the first opening 13. By extending forward, the gripping component 30 can grasp and place the filter in the dust collection box. At the same time, since the sweeper is parked on the front side of the frame 10, in order to facilitate the grasping and placement of the filter in the storage area 14, a second opening 141 can be provided on the rear side of the storage area 14. In this way, when the gripping component 30 grasps and places the filter in the storage area 14, it can avoid the sweeper and ensure the stability of the operation of the replacement mechanism 100.

[0054] Reference Figures 1 to 8 In some embodiments of the present invention, the drive component 20 can drive the gripping component 30 in the front-back direction and the up-down direction. In other words, the gripping component 30 can move in the front-back direction and the up-down direction respectively through the drive component 20, and form a compound motion, so that the gripping component 30 can move freely relative to the frame 10, thereby increasing the movement range of the gripping component 30 and facilitating the replacement of the filter on the sweeper.

[0055] Furthermore, referring to Figures 1 to 8 In some embodiments of the present invention, the rack 10 may include a first frame 11 and a second frame 12.

[0056] The first frame 11 is provided with a third slide rail 111, which extends in the vertical direction and is suitable for the gripping component 30 to be slidably disposed therein. The second frame 12 is provided with a fourth slide rail 121, which extends in the front-back direction and is suitable for the first frame 11 to be slidably disposed therein. This arrangement can improve the movement stability of the gripping component 30 and increase the movement range of the gripping component 30.

[0057] Specifically, under the driving action of the drive component 20, the gripping component 30 can slide along the third slide rail 111 of the first frame 11, so that the gripping component 30 can move in the vertical direction relative to the first frame 11; and under the driving action of the drive component 20, the first frame 11 can slide along the fourth slide rail 121 of the second frame 12, so that the first frame 11 can move in the front-back direction relative to the second frame 12; therefore, through the above, the gripping component 30 can perform complex compound movements on the frame 10 to flexibly move to multiple positions on the frame 10, which facilitates the replacement of the filter components on the sweeper by the gripping component 30 and improves the replacement efficiency.

[0058] Furthermore, the first frame 11 is provided with two third slide rails 111, which are arranged opposite each other in the left and right direction. The second frame 12 is provided with two fourth slide rails 121, which are arranged opposite each other in the left and right direction. This arrangement can improve the movement stability of the gripping component 30 on the first frame 11 and the movement stability of the first frame 11 on the second frame 12.

[0059] Reference Figures 3 to 8 In some embodiments of the present invention, the drive assembly 20 may include a first drive member 21 and a first gear. The first drive member 21 is connected to and drives the first gear to rotate. The first drive member 21 is disposed on the gripping assembly 30. The first gear is rotatably disposed on the first frame 11 in the vertical direction. The first frame 11 is provided with a first rack 112 extending in the vertical direction. The first rack 112 is engaged with the first gear in a transmission manner. In detail, when it is necessary to move the gripping assembly 30 up and down, since the first gear is engaged with the first rack 112 in a transmission manner, and the first drive member 21 can drive the first gear to roll on the first frame 11, the gripping assembly 30 can move up and down relative to the first frame 11, thereby facilitating the replacement mechanism 100 to replace the filter on the sweeper.

[0060] Reference Figures 3 to 8 In other embodiments of the present invention, the drive assembly 20 may further include a second drive member 22 and a second gear. The second drive member 22 is connected to and drives the second gear to rotate. The second drive member 22 is disposed on the first frame 11. The second gear is rotatably disposed on the second frame 12 in the front-back direction. The second frame 12 is provided with a second rack 122 extending in the front-back direction. The second rack 122 is engaged with the second gear in a transmission manner. In detail, when it is necessary to move the gripping assembly 30 back and forth, since the second gear is engaged with the second rack 122 in a transmission manner, and the second drive member 22 can drive the second gear to roll on the second frame 12, the first frame 11 can move back and forth relative to the second frame 12. This allows the gripping assembly 30 to move in the front-back direction relative to the second frame 12, facilitating the replacement mechanism 100 to replace the filter on the sweeper.

[0061] Reference Figures 3 to 8 In some embodiments of the present invention, the frame 10 is provided with a storage box, which has a storage area 14 or multiple storage areas 14 arranged in a vertical direction, which can be used to store filter components, making it convenient to replace the filter components on the sweeper. In addition, the multiple storage areas 14 arranged in a vertical direction on the storage box can save the layout space of the frame 10.

[0062] Reference Figure 1 , Figures 3 to 8In some embodiments of the present invention, the replacement mechanism 100 may further include a cleaning component 40, and the gripping component 30 may further have a third position in which the gripping component 30 can grip and release the filter element from the cleaning component 40, so that the gripping component 30 can replace the clean filter element with the sweeper, thus facilitating the sweeper's cleaning operation on the road surface.

[0063] In conjunction with the foregoing embodiments, driven by the drive component 20, the gripping component 30 can move between a first position, a second position, and a third position. When removing a filter from the sweeper, the gripping component 30 moves to the first position to grip the filter. It can then move from the first position to the third position, where it releases the filter into the cleaning component 40, which cleans the removed filter. Simultaneously, the gripping component 30 can move from the third position to the second position to grip a filter in the storage area 14. It can then move from the second position to the first position, where it places the filter on the sweeper, completing the filter replacement. Alternatively, the gripping component 30 can first move between the first and second positions to replace the filter, and then move between the second and third positions to transfer the filter placed in the storage area 14 to the cleaning component 40 for cleaning.

[0064] Reference Figure 1 , Figures 3 to 8 In some embodiments of the present invention, the cleaning component 40 may include a cleaning box 41 and a cover plate 42. The top of the cleaning box 41 has a third opening 43. The cover plate 42 can open and close the third opening 43. In a third position, the gripping component 30 is located above the third opening 43 and is adapted to grip and place the cover plate 42. With this arrangement, the third opening 43 of the cleaning box 41 is closed by the cover plate 42 to separate the inner and outer spaces of the cleaning box 41 and prevent dirt from splashing when cleaning the filter element. In addition, the third opening 43 can be positioned in conjunction with the positioning structure of the filter element to ensure that the cleaning is carried out normally.

[0065] In detail, the gripping component 30 can grip the filter element to be cleaned and move it to the third position. At this time, the gripping component 30 is located above the third opening 43 and releases the filter element, allowing it to enter the cleaning chamber 41 through the third opening 43. The gripping component 30 can then move towards the cover plate 42 to grip the cover plate 42 and move it to the third position, thereby covering the top of the cleaning chamber 41 with the cover plate 42 to close the third opening 43. Then, the cleaning chamber 41 can begin cleaning the filter element. The cooperation between the cover plate 42 and the third opening 43 of the cleaning chamber 41 ensures that the cleaning process of the filter element takes place within the cleaning chamber 41, preventing dirt from splashing everywhere. Additionally, the filter element may be provided with a positioning structure. When the filter element is placed into the cleaning chamber 41 through the third opening 43, the positioning structure on the filter element can support it at the edge of the third opening 43 to position the filter element and ensure proper cleaning.

[0066] After the filter element is cleaned, the gripping component 30 in the third position can grip the cover plate 42 to remove the cover plate 42 from the top of the cleaning box 41, thereby opening the third opening 43 on the top of the cleaning box 41. Then the gripping component 30 can move to the third position again to grip and move the washed filter element to the storage area 14 for storage as a spare filter element, which is convenient for replacing the filter element on the sweeper.

[0067] Reference Figure 1 , Figures 3 to 8 In some embodiments of the present invention, the gripping component 30 includes a base 31, on which a fifth slide rail and a sixth slide rail are provided opposite each other in the left-right direction. The fifth slide rail and the sixth slide rail extend in the front-back direction. The cover plate 42 is provided with a slider 421, which slides into and out of the fifth slide rail and the sixth slide rail in the front-back direction. With this configuration, the gripping component 30 can grip and place the cover plate 42.

[0068] In detail, when it is necessary to grasp the cover plate 42, the drive assembly 20 can drive the grasping assembly 30 to move toward the cover plate 42. In conjunction with the aforementioned embodiment, the second drive member 22 can drive the first frame 11 to move relative to the second frame 12 in the front-back direction, thereby driving the grasping assembly 30 to move in the front-back direction. Therefore, the second drive member 22 can indirectly drive the seat 31 to move in the front-back direction, so that the slider 421 on the cover plate 42 can slide into the fifth slide rail and the sixth slide rail. Due to the friction between the slider 421 and the fifth slide rail and the sixth slide rail respectively, the cover plate 42 can be stably placed on the seat 31 of the grasping assembly 30. Then, the drive assembly 20 can drive the grasping assembly 30 to move to the third position, so that the cover plate 42 moves to the third position and places the cover plate 42 on the top of the cleaning box 41. Then, the drive assembly 20 can drive the seat 31 to separate from the cover plate 42 and move in the front-back direction, so that the cover plate 42 slides out from the fifth slide rail and the sixth slide rail.

[0069] Reference Figure 1 , Figures 3 to 8 In some embodiments of the present invention, the frame 10 is provided with a resting part 15 for placing the cover plate 42; in conjunction with the foregoing embodiments, the gripping component 30 can be used to grip and place the cover plate 42. Therefore, the driving component 20 can drive the gripping component 30 to move between the resting part 15 and the third position to facilitate the transfer of the cover plate 42, thereby allowing the third opening 43 to be opened and closed through the cover plate 42.

[0070] In some embodiments of the present invention, the cleaning box 41 is provided with a stepped portion, which is suitable for placing the filter element; in conjunction with the foregoing embodiments, the filter element is provided with a positioning structure, and the gripping component 30 mainly replaces the filter element on the sweeper by gripping the positioning structure on the filter element; when the filter element is placed in the cleaning box 41, the positioning structure on the filter element can be placed on the stepped portion of the cleaning box 41, and the filter element can be positioned by the stepped portion to prevent the filter element from falling into the cleaning box 41, and to facilitate the gripping component 30 to grip the positioning structure, thereby transferring the filter element.

[0071] Reference Figures 3 to 8 In some embodiments of the present invention, the cleaning assembly 40 further includes a rinsing assembly 50, which includes a first spray bar 51 and a second spray bar 52. The first spray bar 51 is disposed inside the cleaning tank 41 and is adapted to spray fluid upwards, while the second spray bar 52 is disposed on the cover plate 42 and is adapted to spray fluid downwards. This arrangement can improve the rinsing effect on the filter element.

[0072] Specifically, the flushing assembly 50 can be connected to a water system, which includes a water pump and a water tank. The water pump drives clean water in the water tank to flow to the flushing assembly 50, and the flushing assembly 50 can then spray clean water to flush the filter element. Alternatively, the flushing assembly 50 can be connected to an air system, which includes an airflow drive component. The airflow drive component drives airflow to flow to the flushing assembly 50, and the flushing assembly 50 can then spray airflow to flush the filter element.

[0073] In addition, the rinsing assembly 50 may include a first spray bar 51 and a second spray bar 52. The first spray bar 51 is disposed inside the cleaning tank 41 and can spray fluid upwards. The second spray bar 52 is disposed on the cover plate 42 and can spray fluid downwards. Therefore, through the combined action of the first spray bar 51 and the second spray bar 52, the cleaning effect of the rinsing assembly 50 on the filter element can be improved.

[0074] Reference Figure 1In some embodiments of the present invention, the replacement mechanism 100 further includes a dryer 60, which is mounted on the frame 10 and is adapted to dry the filter element in the cleaning box 41. Specifically, the dryer 60 and the cleaning box 41 can be connected by a pipe. After the cleaning component 40 completes the cleaning of the filter element, the dryer 60 can introduce a high-temperature airflow into the cleaning box 41 through the pipe to dry the filter element in the cleaning box 41.

[0075] Additionally, during the aforementioned drying process, the cover plate 42 can be placed over the cleaning box 41 by the gripping component 30 to seal the cleaning box 41, thereby improving the drying effect of the filter element inside the cleaning box 41. Of course, in some other specific examples, a separate drying box can be provided on the replacement mechanism 100. The drying box has a placement port, and the dryer 60 is connected to the drying box and introduces a high-temperature airflow into the drying box. The cleaned filter element is placed into the drying box through the placement port by the gripping component 30. Subsequently, the dryer 60 can provide a high-temperature airflow into the drying box to dry the filter element. After the drying operation is completed, the gripping component 30 can place the dried filter element in the storage area 14 or directly into the sweeper that needs to be replaced.

[0076] In some specific examples of the present invention, the bottom of the frame 10 may be provided with wheels, or the bottom of the frame may be provided with a chassis. The wheels or chassis and other mechanisms facilitate the movement of the frame 10 on the working surface, so that the replacement mechanism 100 can move toward the sweeper to facilitate the replacement of the filter on the sweeper.
