DETAILED DESCRIPTION

[0032] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0033] The present invention provides a cleaning mechanism 100 that is easy to operate, highly efficient, low-cost, and height-adjustable. The height of the sweeping disc assembly 40 of the cleaning mechanism 100 can be adjusted by an adjustment component 50, thereby improving the applicability of the cleaning mechanism 100. A road sweeper including the cleaning mechanism 100 is also provided.

[0034] Reference Figures 1 to 7 According to the cleaning mechanism 100 of the embodiment of the present invention, the cleaning mechanism 100 includes a mounting seat assembly 10, a first connecting arm 20, a second connecting arm 30, a sweeping disc assembly 40 and an adjustment assembly 50.

[0035] Among them, the first end of the first connecting arm 20 is rotatably connected to the mounting seat assembly 10, and the first connecting arm 20 can swing in the up and down directions, the third end of the second connecting arm 30 is rotatably connected to the mounting seat assembly 10, and the second connecting arm 30 can swing in the up and down directions, the second connecting arm 30 and the first connecting arm 20 are distributed in the up and down directions, the sweeping plate assembly 40 is rotatably connected to the second end of the first connecting arm 20 and the fourth end of the second connecting arm 30, and can move up and down relative to the mounting seat assembly 10, the adjustment component 50 is rotatably connected to any two of the mounting seat assembly 10, the first connecting arm 20, the second connecting arm 30 and the sweeping plate assembly 40, and is configured to adjust the distance between the first connecting arm 20 and the second connecting arm 30; in this way, the height of the sweeping plate assembly 40 is adjustable, thereby improving the applicability of the cleaning mechanism 100.

[0036] Specifically, the mounting base assembly 10, the first connecting arm 20, the second connecting arm 30 and the sweeping plate assembly 40 are rotatably connected to form a four-bar linkage mechanism, and the adjustment component 50 can be rotatably connected to any two of the mounting base assembly 10, the first connecting arm 20, the second connecting arm 30 and the sweeping plate assembly 40. For example, the adjustment component 50 can be rotatably connected to the first connecting arm 20 and the second connecting arm 30 respectively to adjust the distance between the first connecting arm 20 and the second connecting arm 30, thereby driving the four-bar linkage mechanism to move, so that the sweeping plate assembly 40 moves up and down relative to the mounting base assembly 10; for another example, the adjustment component 50 can be rotatably connected to the mounting base assembly 10 and the first connecting arm 20 respectively, and adjust the angle between the mounting base assembly 10 and the first connecting arm 20 to adjust the distance between the first connecting arm 20 and the second connecting arm 30, thereby driving the four-bar linkage mechanism to move, so that the sweeping plate assembly 40 moves up and down relative to the mounting base assembly 10.

[0037] In addition, the spacing between the first connecting arm 20 and the second connecting arm 30 can be understood as the distance from any point on the first connecting line between the first end and the second end of the first connecting arm 20 to the second connecting line between the third end and the fourth end of the second connecting arm 30 along the direction of the perpendicular line of the first connecting line.

[0038] Further, refer to Figures 1 to 4 In some embodiments of the present invention, the adjustment assembly 50 includes a first adjustment member 51 and a second adjustment member 52. One of the first connecting arm 20 and the second connecting arm 30 is hinged to the first adjustment member 51, and the other is provided with a sliding portion 31. The sliding portion 31 is rotatably connected to the first adjustment member 51 and can slide along the first adjustment member 51. The second adjustment member 52 is configured to adjust the relative position of the sliding portion 31 and the first adjustment member 51; in this way, the height adjustment of the sweeping disc assembly 40 can be achieved.

[0039] The first connecting arm 20 is hinged to the first adjusting member 51 , and the second connecting arm 30 is provided with a sliding portion 31 ; or the second connecting arm 30 is hinged to the first adjusting member 51 , and the first connecting arm 20 is provided with a sliding portion 31 .

[0040] Optionally, taking the example in which the first connecting arm 20 is hinged to the first adjusting member 51 and the second connecting arm 30 is provided with a sliding portion 31: the first adjusting member 51 is hinged to the first connecting arm 20 and is rotatably connected to the sliding portion 31 of the second connecting arm 30, and the sliding portion 31 can slide relative to the first adjusting member 51 along the extension direction of the first adjusting member 51, thereby changing the distance between the first connecting arm 20 and the second connecting arm 30; in this process, the operator can control the sliding stroke of the sliding portion 31 on the first adjusting member 51 through the second adjusting member 52 to change the relative position of the sliding portion 31 and the first adjusting member 51, thereby changing the distance between the first connecting arm 20 and the second connecting arm 30, thereby achieving the purpose of height adjustment of the sweeping disc assembly 40.

[0041] Therefore, according to the cleaning mechanism 100 of the embodiment of the present invention, the relative positions of the sliding portion 31 and the first adjusting member 51 are adjusted by the first adjusting member 51 and the second adjusting member 52, and the distance between the first connecting arm 20 and the second connecting arm 30 is adjusted to adjust the height of the sweeping disc assembly 40, thereby improving the operational convenience and efficiency of the height adjustment of the cleaning mechanism 100, avoiding the increased cost caused by replacing the cleaning mechanism 100 every week, and reducing the repair and maintenance cost of the cleaning mechanism 100.

[0042] For ease of understanding, unless otherwise specified, the following description will be made by taking the example that the first connecting arm 20 is hinged to the first adjusting member 51 and the second connecting arm 30 is provided with the sliding portion 31 .

[0043] Reference Figures 1 to 4 In some embodiments of the present invention, the first adjusting member 51 has a first adjusting hole 511, which extends from the second connecting arm 30 to the first connecting arm 20, and the sliding portion 31 is slidably arranged in the first adjusting hole 511 and is rotatable relative to the first adjusting hole 511; in this way, the height adjustment of the sweeping disc assembly 40 can be achieved through the cooperation between the sliding portion 31 and the first adjusting hole 511.

[0044] Specifically, the first adjustment hole 511 extends from the second connecting arm 30 toward the first connecting arm 20 and has two opposing ends. One end of the first adjustment hole 511 is closer to the second connecting arm 30 relative to the first connecting arm 20, and the other end is closer to the first connecting arm 20 relative to the second connecting arm 30. The sliding portion 31 is slidably disposed in the first adjustment hole 511. When the sliding portion 31 is located at one end of the first adjustment hole 511, the sweeping disc assembly 40 is at the highest point of its adjustment travel, and when the sliding portion 31 is located at the other end of the first adjustment hole 511, the sweeping disc assembly 40 is at the lowest point of its adjustment travel. The second adjustment member 52 can control the movement of the sliding portion 31 within the first adjustment hole 511, thereby achieving height adjustment of the sweeping disc assembly 40. Of course, depending on actual circumstances, the sweeping disc assembly 40 can be at the lowest point of its adjustment travel when the sliding portion 31 is located at one end of the first adjustment hole 511, and at the highest point of its adjustment travel when the sliding portion 31 is located at the other end of the first adjustment hole 511.

[0045] Reference Figures 1 to 4 In some embodiments of the present invention, the second adjusting member 52 is transmission-connected to the sliding portion 31 and is threadedly transmitted to the first adjusting member 51, converting the rotational motion of the second adjusting member 52 into linear motion of the second adjusting member 52 along the direction from the second connecting arm 30 to the first connecting arm 20; in this way, the sliding of the sliding portion 31 in the first adjustment hole 511 can be adjusted by the second adjusting member 52, thereby realizing the height adjustment of the sweeping disc assembly 40.

[0046] In detail, the first adjusting member 51 has a threaded hole, and the outer peripheral surface of the second adjusting member 52 is provided with a thread, and the second adjusting member 52 is inserted into the threaded hole of the first adjusting member 51; when adjusting the height of the sweeping disc assembly 40, the operator can rotate the second adjusting member 52. Under the threaded transmission of the second adjusting member 52 and the first adjusting member 51, the second adjusting member 52 can move from the second connecting arm 30 to the first connecting arm 20, or from the first connecting arm 20 to the second connecting arm 30, to drive the sliding part 31 to move between the opposite ends of the first adjustment hole 511, thereby realizing the height adjustment of the sweeping disc assembly 40.

[0047] Reference Figures 1 to 4 In some embodiments of the present invention, the adjustment component 50 also includes a first elastic member 53, which connects the first connecting arm 20 and the second connecting arm 30, and has an elastic force that drives the first connecting arm 20 and the second connecting arm 30 away from each other, so that the sweeping disc assembly 40 moves upward; this can improve the convenience of adjustment and facilitate the operator to adjust the height of the sweeping disc assembly 40.

[0048] For details, refer to Figure 3 and Figure 4When the first connecting arm 20 and the second connecting arm 30 approach each other, the sweeping disc assembly 40 moves downward relative to the mounting base assembly 10, and when the first connecting arm 20 and the second connecting arm 30 move away from each other, the sweeping disc assembly 40 moves upward relative to the mounting base assembly 10. In this way, when the height of the sweeping disc assembly 40 is lowered, the second adjusting member 52 can overcome the elastic force of the first elastic member 53, thereby driving the sliding portion 31, so that the distance between the first connecting arm 20 and the second connecting arm 30 approaches each other is reduced, thereby causing the sweeping disc assembly 40 to move downward; when the height of the sweeping disc assembly 40 is raised, the second adjusting member 52 can release the drive to the sliding portion 31, and at this time the first elastic member 53 can overcome the gravity of the sweeping disc assembly 40, drive the first connecting arm 20 and the second connecting arm 30 away from each other, so that the sweeping disc assembly 40 moves upward.

[0049] Reference Figures 1 to 4 In some embodiments of the present invention, the second adjusting member 52 abuts against the sliding portion 31 to drive the first connecting arm 20 and the second connecting arm 30 closer to each other, so that the sweeping disc assembly 40 moves downward; in this way, the height of the sweeping disc assembly 40 can be adjusted by the second adjusting member 52.

[0050] There are many ways for the second adjusting member 52 to abut against the sliding portion 31. The present invention provides the following embodiments for illustration:

[0051] Implementation Method 1

[0052] Reference Figures 1 to 4 When the sweeping disc assembly 40 is lowered, the second adjusting member 52 can overcome the elastic force of the first elastic member 53 and abut against the driving sliding member 31 to move in the direction from the upper end to the lower end of the first adjusting hole 511, so that the first connecting arm 20 and the second connecting arm 30 are close to each other, thereby lowering the sweeping disc assembly 40; when the sweeping disc assembly 40 is lifted, the second adjusting member 52 can release the drive of the sliding member 31. At this time, the first elastic member 53 can overcome the gravity of the sweeping disc assembly 40, so that the sliding member 31 can move in the direction from the lower end to the upper end of the first adjusting hole 511, so that the first connecting arm 20 and the second connecting arm 30 are away from each other, thereby lifting the sweeping disc assembly 40.

[0053] Implementation Method 2

[0054] In the bottom-up direction, the first connecting arm 20 and the second connecting arm 30 are distributed in sequence, the first adjusting member 51 is hinged to the second connecting arm 30, the first connecting arm 20 is provided with a sliding portion 31, and the second adjusting member 52 drives the sliding portion 31 to slide in the first adjusting hole 511; when the sweeping disc assembly 40 is lowered, the second adjusting member 52 can release the drive of the sliding portion 31, and the sweeping disc assembly 40 can move downward under the action of gravity, so that the first connecting arm 20 and the second connecting arm 30 are close to each other, thereby lowering the sweeping disc assembly 40; when the sweeping disc assembly 40 is lifted, the second adjusting member 52 can overcome the gravity of the sweeping disc assembly 40, and abut against the driving sliding portion 31 to move along the direction from the lower end to the upper end of the first adjusting hole 511, so that the first connecting arm 20 and the second connecting arm 30 are away from each other, thereby lifting the sweeping disc assembly 40.

[0055] Combined with the above-mentioned embodiment 1, refer to Figures 1 to 4 In some embodiments of the present invention, the adjustment component 50 also includes a first elastic member 53, the first elastic member 53 connects the position near the first end of the first connecting arm 20 and the position near the fourth end of the second connecting arm 30, and the first adjustment member 51 connects the position near the second end of the first connecting arm 20 and the position near the third end of the second connecting arm 30; in this way, the height adjustment of the sweeping disc assembly 40 can be achieved, thereby improving the applicability of the cleaning mechanism 100.

[0056] Specifically, the mounting seat assembly 10, the first connecting arm 20, the second connecting arm 30 and the sweeping plate assembly 40 are rotatably connected to form a quadrilateral, and the first elastic member 53 is arranged roughly along the main diagonal of the quadrilateral, that is, the first elastic member 53 is connected to a position close to the first end of the first connecting arm 20 compared to the second end of the first connecting arm 20, and is connected to a position close to the fourth end of the second connecting arm 30 compared to the third end of the second connecting arm 30; the first adjusting member 51 is arranged roughly along the secondary diagonal of the quadrilateral, that is, the first adjusting member 51 is connected to a position close to the second end of the first connecting arm 20 compared to the first end of the first connecting arm 20, and is connected to a position close to the third end of the second connecting arm 30 compared to the fourth end of the second connecting arm 30.

[0057] The first elastic member 53 has an elastic force that drives the first end of the first connecting arm 20 and the fourth end of the second connecting arm 30 to approach each other, so that the first connecting arm 20 and the second connecting arm 30 move away from each other, thereby driving the sweeping plate assembly 40 to rise; the cooperation of the first adjusting member 51, the sliding part 31 and the second adjusting member 52 can drive the first connecting arm 20 and the second connecting arm 30 to approach each other, thereby driving the sweeping plate assembly 40 to descend; in short, in the structural arrangement, the first elastic member 53 and the first adjusting member 51 are arranged roughly along the two diagonals of the quadrilateral, so as to facilitate the height adjustment function of the adjustment component 50 on the sweeping plate assembly 40.

[0058] Reference Figures 1 to 4 In some embodiments of the present invention, the mounting seat assembly 10, the first connecting arm 20, the second connecting arm 30 and the sweeping disc assembly 40 are connected to form a parallelogram linkage mechanism; specifically, the sweeping disc assembly 40 includes bristles. After the bristles are worn, the height of the sweeping disc assembly 40 can be lowered by the adjustment component 50 so that the bristles maintain the cleaning effect on the road surface. Therefore, the mounting seat assembly 10, the first connecting arm 20, the second connecting arm 30 and the sweeping disc assembly 40 can be connected to form a parallelogram linkage mechanism. In this way, before and after the height of the sweeping disc assembly 40 is adjusted, the bristles of the sweeping disc assembly 40 can always face the road surface, thereby ensuring the cleaning effect of the cleaning mechanism 100.

[0059] In some specific examples of the present invention, the sliding portion 31 passes through one side of the first adjustment hole 511 and exits from the other side of the first adjustment hole 511, and the periphery of one side of the first adjustment hole 511 abuts against the second connecting arm 30. A fourth elastic member 54 is connected between the first adjustment member 51 and the second connecting arm 30. The fourth elastic member 54 has an elastic force that drives the first adjustment member 51 close to the second connecting arm 30, thereby preventing the sliding portion 31 from falling off from the first adjustment hole 511 and improving the stability of the cleaning mechanism 100.

[0060] In combination with embodiment 1, in other specific examples of the present invention, the first adjusting member 51 has a second adjusting hole 512, the second adjusting hole 512 extends from the second connecting arm 30 to the direction of the first connecting arm 20, the sliding portion 31 is slidably arranged in the second adjusting hole 512 and is rotatable relative to the second adjusting hole 512, and the sliding portion 31 is detachably arranged in the second adjusting hole 512, and the sliding portion 31 is detachably arranged in the first adjusting hole 511, for switching the sliding portion 31 between the first adjusting hole 511 and the second adjusting hole 512; in the non-working stage, the sliding portion 31 can be set in the second adjusting hole 512, and the sliding portion 31 is located at the upper end of the second adjusting hole 512 under the action of the first elastic member 53; in the working stage, the sliding portion 31 can be set in the first adjusting hole 511, and if the height of the sweeping disc assembly 40 needs to be adjusted, it can be adjusted through the second adjusting member 52; or, if it has been adjusted in the last working stage, the sliding portion 31 can be directly set in the first adjusting hole 511 so that the sweeping disc assembly 40 is at the adjusted height.

[0061] Reference Figures 1 to 6 In some embodiments of the present invention, the sweeping disc assembly 40 includes a first base body 41 , a second base body 42 and a limiting component 43 .

[0062] Among them, the first seat body 41 is rotatably connected to the first connecting arm 20 and the second connecting arm 30, and moves in the up and down directions relative to the mounting seat assembly 10, the second seat body 42 is rotatably connected to the first seat body 41 and can swing in the left and right directions, and the limit assembly 43 is provided on the first seat body 41, and is configured to drive the second seat body 42 to reset when the second seat body 42 swings left and right; in this way, flexible obstacle avoidance of the sweeping disc assembly 40 can be achieved, thereby improving the applicability of the cleaning mechanism 100.

[0063] Specifically, the sweeping disc assembly 40 has a left swing position, an initial position and a right swing position in the direction from left to right; when the cleaning mechanism 100 is operating normally, the sweeping disc assembly 40 is in the initial position. When the sweeping disc assembly 40 encounters an obstacle, driven by the obstacle, the second seat body 42 swings along the left and right directions relative to the first seat body 41 to the left swing position or the right swing position, and after leaving the obstacle, the limiting component 43 can drive the second seat body 42 to swing back to the initial position along the left and right directions, thereby realizing flexible obstacle avoidance of the sweeping disc assembly 40.

[0064] In addition, the sweeping disc assembly 40 also includes a sweeping disc 46, a driving member 44 and an anti-collision member 45. The driving member 44 and the anti-collision member 45 are connected to the second base body 42. The sweeping disc 46 is connected to the drive shaft of the driving member 44. The anti-collision member 45 is arranged around the axis of the drive shaft and is located on the outside of the sweeping disc 46 to prevent the sweeping disc 46 from interfering with obstacles.

[0065] Reference Figures 1 to 5 In some embodiments of the present invention, the limiting assembly 43 includes a first limiting member 431, a second limiting member 432 and a second elastic member 433. The first seat body 41 is rotatably connected and abutted with the first limiting member 431. The first seat body 41 is rotatably connected and abutted with the second limiting member 432, which is used to limit the relative closing of the first limiting member 431 and the second limiting member 432. The second elastic member 433 is connected to the first limiting member 431 and the second limiting member 432, and has an elastic force that drives the first limiting member 431 and the second limiting member 432 to close relative to each other; in this way, the flexible obstacle avoidance of the sweeping disc assembly 40 can be achieved, and the applicability of the cleaning mechanism 100 can be improved.

[0066] Specifically, when the sweeping plate assembly 40 encounters an obstacle, the second base body 42 is driven by the obstacle to swing leftward relative to the first base body 41, and abuts against and drives the first limiting member 431 to swing leftward. At this time, the second limiting member 432 abuts against the first base body 41 and cannot swing leftward. After the sweeping plate assembly 40 is free from the obstacle, the second elastic member 433 can drive the first limiting member 431 to swing rightward, and swing to a position abutting against the first base body 41, and abutting against and drives the second base body 42 to swing rightward back to the initial position. Similarly, when the sweeping plate assembly 40 encounters an obstacle, the obstacle drives the second base 42 to swing rightward relative to the first base 41, and abuts against the second limiting member 432 to swing rightward. At this time, the first limiting member 431 abuts against the first base 41 and cannot swing leftward. After the sweeping plate assembly 40 escapes the obstacle, the second elastic member 433 can drive the second limiting member 432 to swing leftward, and swing to a position abutting against the first base 41, and abutting against the second base 42 to swing leftward back to the initial position. In addition, in the initial position, the first limiting member 431 and the second limiting member 432 are abutted by the first base 41 and cannot be relatively closed due to the action of the second elastic member 433.

[0067] More specifically, the first stopper 431 has a first abutting surface, and the first base 41 has a second abutting surface. The minimum distance from the first abutting surface to the rotational center of the first stopper 431 and the first base 41 is greater than the minimum distance from the second abutting surface to the rotational center. Thus, in the initial position, the first abutting surface and the second abutting surface abut and cooperate, and the stopper can rotate away from the second abutting surface to a leftward swing position. The second stopper 432 cooperates with the first base 41 in a similar manner and will not be further described here.

[0068] Reference Figures 1 to 4 In some embodiments of the present invention, the mounting seat assembly 10 includes a third seat body 11, a fourth seat body 12 and a third adjusting member 13. The fourth seat body 12 is rotatably connected to the third seat body 11 and can swing in the left and right directions. The fourth seat body 12 is rotatably connected to the first connecting arm 20 and the second connecting arm 30, and moves in the up and down directions relative to the sweeping disc assembly 40. The third adjusting member 13 is movably provided on the fourth seat body 12. The third seat body 11 is provided with a positioning hole 112. The third adjusting member 13 can be detachably plugged into the positioning hole 112; in this way, the sweeping disc assembly 40 can be retracted, making it easier for the road sweeper to pass through narrow roads.

[0069] Specifically, the third base body 11 is connected to the body of the sweeper, and the fourth base body 12 is connected to the first connecting arm 20 and the second connecting arm 30; when it is necessary to pass through a narrow road, the fourth base body 12 is swung toward the inside of the body of the sweeper in the left and right directions relative to the third base body 11, and the third adjusting member 13 of the fourth base body 12 is inserted into the positioning hole 112 of the third base body 11, so that the sweeping disc assembly 40 is retracted inside the body, making it easier for the sweeper to pass through narrow roads.

[0070] Reference Figure 1 、 Figure 2 、 Figure 6 and Figure 7 In some embodiments of the present invention, the third seat body 11 has a third adjustment hole 111, the third adjustment hole 111 extends along the rotation direction of the fourth seat body 12, and has two opposite ends, the third adjustment member 13 can be detachably plugged into the third adjustment hole 111, and the third adjustment member 13 abuts against one end of the third adjustment hole 111 when the fourth seat body 12 is in the extended position, and the third adjustment member 13 abuts against the other end of the third adjustment hole 111 when the fourth seat body 12 is in the stored position; in this way, flexible obstacle avoidance of the sweeping disc assembly 40 can be achieved, thereby improving the applicability of the cleaning mechanism 100.

[0071] In detail, the third adjustment hole 111 has two opposite ends, one end of the third adjustment hole 111 is relatively far away from the body of the sweeper, and the other end is relatively close to the body of the sweeper; during normal operation, the third adjustment member 13 of the fourth seat body 12 is inserted into the third adjustment hole 111 and is located at one end of the third adjustment hole 111, that is, the swing-out position, so that the sweeping disc assembly 40 is swung out; when encountering an obstacle, driven by the obstacle, the fourth seat body 12 rotates relative to the third seat body 11 and the third adjustment member 13 moves from one end of the third adjustment hole 111 to the other end of the third adjustment hole 111 to switch to the storage position, so that the sweeping disc assembly 40 is retracted to achieve obstacle avoidance.

[0072] Reference Figure 1 、 Figure 2 、 Figure 6 and Figure 7 In some embodiments of the present invention, the fourth seat body 12 has a swing-out position and a storage position, and the mounting seat assembly 10 also includes a third elastic member 14, which has an elastic force that drives the fourth seat body 12 to move toward the swing-out position; specifically, the third elastic member 14 applies an elastic force to the fourth seat body 12, so that the fourth seat body 12 is maintained in the swing-out position during normal operation, and is driven to move to the swing-out position after obstacle avoidance is completed, thereby improving the working efficiency of the cleaning mechanism 100.

[0073] Reference Figures 1 to 7 According to the road sweeper of the embodiment of the present invention, the road sweeper includes the cleaning mechanism 100 in the above embodiment. By applying the above cleaning mechanism 100, the operation convenience and maintenance efficiency of the road sweeper can be improved, and the cost of the road sweeper can be reduced.

[0074] Specifically, the first connecting arm 20 and the second connecting arm 30 are distributed from bottom to top, the first adjusting member 51 is hinged to the first connecting arm 20, the second connecting arm 30 is provided with a sliding portion 31, the sliding portion 31 slides and can rotate in the first adjusting hole 511 of the first adjusting member 51, and the second adjusting member 52 is in abutment with the sliding portion 31.

[0075] 1. Adjustment process of lowering the sweeping disc assembly 40:

[0076] Rotate the second adjusting member 52 so that the second adjusting member 52 overcomes the elastic force of the first elastic member 53, driving the sliding portion 31 to slide from the upper end of the first adjusting hole 511 to the lower end of the first adjusting hole 511, so that the first connecting arm 20 and the second connecting arm 30 approach each other, thereby causing the sweeping disc assembly 40 to descend.

[0077] 2. Adjustment process of lifting sweeping disc assembly 40:

[0078] Rotate the second adjusting member 52 to release the drive on the sliding part 31. Under the action of the first elastic member 53, the sliding part 31 slides from the lower end of the first adjusting hole 511 to the upper end of the first adjusting hole 511, so that the first connecting arm 20 and the second connecting arm 30 approach each other, thereby lifting the sweeping disc assembly 40.

[0079] The aforementioned adjustment process facilitates adjusting the working height of the sweeper's sweeper disc assembly 40 to suit the height of the work area. This provides convenient and efficient operation, and the sweeper disc 46 can be used on flat ground, curbs, and steps, expanding the sweeper's operating range. Furthermore, the height of the sweeper disc 46 can be adjusted based on its wear, reducing the frequency of disc replacement and lowering the cost of the sweeper.

[0080] 3. Flexible obstacle avoidance process of the sweeping plate assembly 40:

[0081] When the sweeping plate assembly 40 encounters an obstacle, the second base body 42 swings left and right relative to the first base body 41, and one of the first limiting member 431 and the second limiting member 432 will be driven by the second base body 42 to swing left and right following the second base body 42, while the other one abuts and cooperates with the first base body 41 to maintain its original position. After the sweeping plate assembly 40 is free from the obstacle, the second elastic member 433 drives one of the first limiting member 431 and the second limiting member 432 to return to its original position, and drives the second base body 42 to return to its original position.

[0082] The aforementioned flexible obstacle avoidance process allows the road sweeper to quickly pass through narrow sections such as sidewalk barriers; and the sweeping disc assembly 40 can swing forward or backward to avoid obstacles, and can adapt to more complex working conditions.

[0083] 4. Retraction process of the sweeping disc assembly 40:

[0084] When the road sweeper needs to pass through a narrow road, the fourth base body 12 can be driven to swing toward the inside of the road sweeper body in the left and right directions relative to the third base body 11, and the third adjustment member 13 on the fourth base body 12 can be inserted into the positioning hole 112 of the third base body 11 to achieve the inward retraction of the sweeping disc assembly 40, making it easier for the road sweeper to pass through narrow roads.

[0085] The aforementioned retraction process facilitates reducing the width of the road sweeper, making the storage and transportation of the road sweeper more efficient; and reduces the sweeping width of the road sweeper, allowing the road sweeper to go to narrow roads for cleaning operations.

[0086] In addition, in related art, the lifting system of the sweeper's cleaning mechanism uses an electric push rod as a power source. However, during operation, splashing sand and water vapor can cover the electric push rod, easily causing the electric push rod to become stuck and rust, leading to burnout of the electric push rod motor. In the embodiment of the present utility model, the lifting and lowering adjustment of the sweeping mechanism 100 is achieved by manually driving the second adjustment member 52, which can avoid the above-mentioned problem.
