[0037] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0038] The road surface cleaning system for a washing and sweeping vehicle and the washing and sweeping vehicle of the present invention will be described below with reference to the accompanying drawings.

[0039] like Figure 1 As shown, the utility model provides a road cleaning system for a washing and sweeping vehicle, wherein the road cleaning system for a washing and sweeping vehicle comprises:

[0040] The nozzle driving device includes a first driving mechanism 1, a nozzle assembly 2 and a sliding track 3. The sliding track 3 is arranged on the chassis of the cleaning and sweeping vehicle and extends along the width direction of the chassis. The nozzle assembly 2 is movably arranged on the sliding track 3. The first driving mechanism 1 is arranged on the chassis and is drivingly connected to the nozzle assembly 2 so as to drive the nozzle assembly 2 to move along the sliding track 3.

[0041] When using the above-mentioned road cleaning system for the washing and sweeping vehicle, it includes a nozzle driving device, which includes a first driving mechanism 1, a nozzle assembly 2 and a sliding track 3. The sliding track 3 is arranged on the chassis and extends along the width direction of the chassis. The first driving mechanism 1 is arranged on the chassis and is drivingly connected to the nozzle assembly 2. The first driving mechanism 1 can drive the nozzle assembly 2 to move along the sliding track 3, thereby expanding the working range of the nozzle assembly 2. According to the distribution of garbage on the road surface, the nozzle assembly 2 can be moved to the top of the garbage to avoid missing garbage.

[0042] Specifically, in order to obtain the garbage distribution on the road surface, an image acquisition device 7 can be set on the chassis. The control of the first drive mechanism 1 can be manual operation or automatic operation through a controller. If manual operation is adopted, a display screen connected to the image acquisition device 7 is arranged in the cab. The operator can observe the road conditions through the display screen, thereby controlling the first drive mechanism 1 to adjust the position of the suction nozzle assembly 2; if the controller is used for automatic operation, the image recognition algorithm can be used to calculate the horizontal distance between the garbage and the suction nozzle assembly 2, and then the corresponding drive instruction is sent to the first drive mechanism 1 to move the suction nozzle assembly 2 to the corresponding position.

[0043] In the embodiment of the utility model, the nozzle driving device further includes a slider 4, which is movably arranged on the sliding track 3 and connected to the nozzle assembly 2. The nozzle assembly 2 is slidably connected to the chassis through the sliding track 3 and the slider 4, and the position is adjusted by the first driving mechanism 1. During the driving of the washing and sweeping vehicle, the resistance of the nozzle assembly 2 is directly transmitted to the chassis through the slider 4 and the sliding track 3. Compared with the solution in which the first driving mechanism 1 is used as a connecting piece between the nozzle assembly 2 and the chassis, the load of the first driving mechanism 1 is reduced.

[0044] like Figure 3 As shown, in the embodiment of the utility model, the sliding track 3 is formed with a sliding groove 31 with an opening facing downward, and the slider 4 includes a main body 41 and a connecting portion 42 connected to the main body 41. The main body 41 is placed in the sliding groove 31, and the opening width of the sliding groove 31 is smaller than the width of the main body 41. The connecting portion 42 extends from the opening of the sliding groove 31 and connects the suction nozzle assembly 2. When the suction nozzle assembly 2 moves with the washing and sweeping vehicle, the suction nozzle assembly 2 is subjected to a large impact due to reasons such as bumpy road conditions, the washing and sweeping vehicle turning or high-speed movement. Through the above-mentioned arrangement, the sliding track 3 surrounds the slider 4 as a whole, and the impact resistance is stronger.

[0045] Specifically, a certain margin may be left between the groove wall of the sliding groove 31 and the sliding block 4, so that the suction nozzle assembly 2 can move slightly relative to the washing and sweeping vehicle to adapt to uneven road conditions.

[0046] like Figure 1 As shown, in the embodiment of the utility model, the nozzle assembly 2 includes a nozzle body 21 and a connecting bracket 22, the sliding track 3 is arranged at the front side of the nozzle body 21, and the installation height of the sliding track 3 is higher than the nozzle body 21, one end of the connecting bracket 22 is connected to the slider 4, and the other end is connected to the nozzle body 21, the first driving mechanism 1 is placed horizontally on the chassis, and the first telescopic end 11 is drivingly connected to the connecting bracket 22. Since the height of the space between the chassis of the washing and sweeping vehicle and the road surface is limited, the front-to-back staggered arrangement of the nozzle body 21 and the sliding track 3 is realized by the connecting bracket 22, which effectively utilizes the chassis space and facilitates the setting of the air duct pipeline on the nozzle body 21.

[0047] In the embodiment of the utility model, there are two connecting brackets 22, and the two connecting brackets 22 are arranged in parallel and spaced apart. The first driving mechanism 1 is a double-acting cylinder, and the double-acting cylinder is placed between the two connecting brackets 22 and has a first telescopic end 11 and a second telescopic end 12, and the first telescopic end 11 and the second telescopic end 12 are respectively connected to the two connecting brackets 22 in a one-to-one correspondence. The two connecting brackets 22 are synchronously driven by the double-acting cylinder, so that the overall force of the nozzle body 21 is balanced.

[0048] In an embodiment of the utility model, the connecting bracket 22 includes a connecting rod 221 and a connecting plate 222. One end of the connecting rod 221 is connected to the suction nozzle body 21, and the other end is formed with a connecting hole that passes through horizontally (along the width direction of the chassis). One end of the connecting plate 222 is detachably connected to the connecting rod 221 through a threaded fastener passing through the connecting hole, and the other end is connected to the slider 4.

[0049] Specifically, the connecting plate 222 is arranged on the outside of the connecting rod 221. Since the two sides of the suction nozzle body 21 are also provided with suction nozzles, nozzles and other structures, the position for the installation of the connecting rod 221 is limited. In addition, the connecting rod 221 is a transmission component. In order to meet the structural strength requirements, the width of the connecting rod 221 itself is relatively large. If the first drive mechanism 1 is directly connected to the connecting rod 221, the first drive mechanism 1 can only use a small double-acting cylinder with limited stroke due to the spacing between the two connecting rods 221. By splitting the connecting bracket 22 into two parts, the connecting rod 221 and the connecting plate 222, the connecting plate 222 is arranged at one end of the connecting rod 221 away from the suction nozzle body 21, and the installation is not restricted, which can provide a larger installation space for the first drive mechanism 1, and ensure that the movement range of the suction nozzle body 21 meets the use requirements. In addition, by splitting the connecting bracket 22 into two parts, the connecting rod 221 and the connecting plate 222, the installation of the suction nozzle assembly 2 is more convenient. The connecting plate 222 can be set as an integrated structure with the slider 4, or a detachable connection can be achieved by setting bolts.

[0050] In an embodiment of the utility model, the road cleaning system for a washing and sweeping vehicle also includes a control platform and a controller. A mode switching button is provided on the control platform. The mode switching button is used to select the cleaning mode. The controller is used to determine the position to be cleaned according to the cleaning mode. The operator can select the corresponding cleaning mode according to actual needs to meet the cleaning needs under different working conditions.

[0051] Specifically, the control platform also includes a storage medium for storing the running program of the cleaning mode, and the cleaning mode includes but is not limited to the automatic mode, the edge mode and the manual mode:

[0052] In automatic mode, the location to be cleaned refers specifically to the garbage location, see Figure 4 , there is garbage on the right side of the washing and sweeping vehicle. After the image acquisition device 7 acquires the road surface image, the controller calculates the distance L0 between the garbage and the suction nozzle assembly 2, and controls the first driving mechanism 1 to drive the suction nozzle assembly 2 to move rightward by L0 to suck up the garbage. Then the first driving mechanism 1 drives the suction nozzle assembly 2 to return to its original position. In the automatic mode, by controlling the suction nozzle assembly 2 to move left and right in a straight line, if the sweeping disc misses sweeping, the missed garbage can be sucked into the garbage bin of the washing and sweeping vehicle, thereby reducing the missed sweeping situation;

[0053] In the edge-adjacent mode, the position to be cleaned specifically refers to the position of the curb. When the operator selects the edge-adjacent mode through the mode switching button, the image acquisition device 7 acquires the road surface image, and the controller calculates the distance L1 between the curb and the suction nozzle assembly 2, and controls the first driving mechanism 1 to drive the suction nozzle assembly 2 to move left or right by L1 to operate close to the curb. After the operation is completed, the first driving mechanism 1 drives the suction nozzle assembly 2 to return to its original position;

[0054] The control platform is also provided with a movement button for manually controlling the first driving mechanism 1. When the operator selects the manual mode through the mode switching button, the movement button can be used to control the first driving mechanism 1 to drive the suction nozzle assembly 2 to move left and right.

[0055] like Figure 2 and Figure 4 As shown, in an embodiment of the utility model, the road cleaning system for a washing and sweeping vehicle also includes a sweeping disc driving device arranged on the front side of the suction nozzle driving device, the sweeping disc driving device includes a second driving mechanism 5, a mounting bracket 8, a connecting sleeve 9 and a sweeping disc assembly 6, the mounting bracket 8 is arranged on the chassis, and extends laterally from the chassis to form a sliding rod 81 for sliding connection of the connecting sleeve 9, the sweeping disc assembly 6 is connected to the connecting sleeve 9, the fixed end of the second driving mechanism 5 is connected to the mounting bracket 8, and the driving end is connected to the connecting sleeve 9, and the second driving mechanism 5 is used to drive the connecting sleeve 9 to move.

[0056] Specifically, similar to the first driving mechanism 1, the control of the second driving mechanism 5 can be manual operation or automatic operation through a controller. If manual operation is adopted, the operator can observe the road conditions through the display screen, thereby controlling the second driving mechanism 5 to adjust the position of the sweeping disc assembly 6; if automatic operation is adopted by the controller, the image recognition algorithm can be used to calculate the horizontal distance between the sweeping disc assembly 6 and the curb or road line, and then the corresponding driving instruction is issued to the second driving mechanism 5 to make the outer edge of the sweeping disc assembly 6 flush with the curb or road line.

[0057] It should be noted that in the embodiment of the utility model, the positions to be cleaned defined by the controller based on the sweeping disc assembly 6 and the suction nozzle assembly 2 are not completely the same. For the sweeping disc assembly 6, the position to be cleaned refers to the curb or road line; for the suction nozzle assembly 2, as described above, the position to be cleaned can be the curb or road line, or the garbage position.

[0058] In a specific embodiment of the present invention, the control principle of the controller on the sweeping disc assembly 6 is:

[0059] The controller calculates the distance L2 between the sweeping disc assembly 6 and the curb (road line) through the image information between the two and sends it to the controller through the CAN bus. The controller makes a judgment based on the value of L2. When L2>0, the controller controls the second drive mechanism 5 to extend the sweeping disc assembly 6 by L2. When L2<0, the controller controls the second drive mechanism 5 to extend the sweeping disc assembly 6 by L2. In this way, it can be ensured that the width of the sweeping disc assembly 6 during cleaning can always be kept consistent with the actual width of the road, achieving the purpose of not missing any sweeps, and ensuring that the same sweeper can adapt to different scenarios.

[0060] Specifically, the sweeping disc assembly 6 includes a mounting seat 61, a third driving mechanism, a movable plate 63 and a sweeping disc body 64. The mounting seat 61 is connected to the connecting sleeve 9. The two ends of the movable plate 63 are respectively hinged to the mounting seat 61 and the sweeping disc body 64 in a one-to-one correspondence. The fixed end of the third driving mechanism is connected to the mounting seat 61, and the driving end is connected to the movable plate 63. The movable plate 63 is driven by the third driving mechanism to swing up and down, thereby adjusting the height of the sweeping disc body 64.

[0061] In the embodiment of the utility model, the road cleaning system for the washing and sweeping vehicle further comprises two image acquisition devices 7 for acquiring road surface images. The two image acquisition devices 7 are respectively arranged on the left and right sides of the chassis and are located in front of the sweeping disc driving device.

[0062] Specifically, the image acquisition device 7 is set as a camera, and the camera is connected to the controller in communication. The controller determines the distance between the position to be cleaned and the suction nozzle assembly 2 and / or the sweeping disc assembly 6 according to the road surface image. As the washing and sweeping vehicle moves, the camera shoots the road surface in front of the sweeping disc assembly 6 and transmits the image to the controller. The controller determines the pixel position of the position to be cleaned in the image according to the cleaning mode, and calculates the distance between the position to be cleaned and the suction nozzle assembly 2 and / or the sweeping disc assembly 6 with the position of the camera as the origin. The length of the shooting range of the camera is b, the width is a, and the pixel of the camera is 640×400. Assuming that the position to be cleaned is the 500th pixel in the second row in the image, the lateral distance L between this point and the origin is:

[0063] L = (500 ÷ 640) × b;

[0064] The controller then controls the first driving mechanism 1 and / or the second driving mechanism 5 to operate accordingly according to the lateral distance L.

[0065] Furthermore, sweeping disc driving devices are provided on both sides of the washing and sweeping vehicle. Through two cameras, the distance from the curbs on both sides to the sweeping disc assemblies 6 of the sweeping disc driving devices on both sides can be obtained at the same time. The controller controls the second driving mechanisms 5 on both sides separately to drive the sweeping disc assemblies 6 on both sides to extend or retract accordingly.

[0066] Of course, the utility model is not limited to this. In addition to calculating the distance between the position to be cleaned and the sweeping disc assembly 6 or the suction nozzle assembly 2 through a camera and an image recognition algorithm, distance measurement can also be performed through radar, laser rangefinder, etc. The first drive mechanism 1, the second drive mechanism 5 and the third drive mechanism can use hydraulic cylinders, air cylinders, electric push rods, etc.

[0067] In order to achieve the above-mentioned objectives, the utility model also provides a washing and sweeping vehicle, which includes the above-mentioned road cleaning system for washing and sweeping vehicles. Since the washing and sweeping vehicle adopts all technical solutions of the above-mentioned road cleaning system for washing and sweeping vehicles, the washing and sweeping vehicle provided by the utility model is adaptable to a variety of road scenes, reducing the user's need to purchase more types of sweepers, thereby saving use costs and reducing the missed sweeping rate.
