[0020] In order to make the contents of the present invention easier to understand, the technical solution of the present invention is further described below in conjunction with specific implementation methods and drawings, but the present invention is not limited thereto.

[0021] Embodiment 1 See also Figure 1 and Figure 7 The present invention provides a technical solution: an intelligent sanitation vehicle, including a body 9, a cleaning mechanism 1 is arranged at the front of the bottom of the body 9, the cleaning mechanism 1 includes two sweeping discs 101 arranged symmetrically on the left and right, a suction nozzle assembly 2 is arranged at the bottom of the body 9, the suction nozzle assembly 2 is arranged at the rear side of the sweeping disc 101, a camera 3 and a laser radar 4 are arranged at the front of the top of the body 9, a vehicle-end controller is arranged in the body 9, the camera 3 and the laser radar 4 are respectively communicated with the vehicle-end controller, and the camera 3 and the laser radar 4 are enabled to recognize the situation of the road ahead by giving the vehicle a large amount of pictures and other materials for learning in the early stage.

[0022] From the above description, it can be seen that the combination of the camera 3 and the laser radar 4 can identify garbage and debris on the road, distinguish the amount and type of garbage, and then control the sweeping discs 101 on both sides to rotate through the vehicle-end controller to sweep the garbage to the middle, so that the suction nozzle assembly 2 can transport the garbage to the garbage bin 6 through wind power.

[0023] As a further preference of this embodiment, a side wall of the vehicle body 9 is provided with an inspection door 8, through which various circuits and fan devices in the vehicle body 9 can be inspected.

[0024] Embodiment 2 The cleaning mechanism 1 also includes a swing arm 102, and both sides of the swing arm 102 are respectively connected to the corresponding sweeping disc 101. A swing arm fixing frame 103 is symmetrically fixedly arranged at the bottom of the vehicle body 9, and a sweeping disc lifting cylinder 104 is fixedly arranged on the swing arm fixing frame 103. The sweeping disc lifting cylinder 104 is inclined, and both sides of the swing arm 102 are respectively fixedly connected to the output ends of the corresponding sweeping disc lifting cylinder 104.

[0025] From the above description, it can be known that by controlling the extension and retraction of the sweeping disc lifting cylinder 104, the swing arm 102 moves up and down, thereby driving the sweeping discs 101 on both sides to move up and down to adapt to different road conditions; when the sweeping disc lifting cylinder 104 is extended, the swing arm 102 connected to the output end of the sweeping disc lifting cylinder 104 moves downward, driving the sweeping discs 101 connected on both sides to move downward; when the sweeping disc lifting cylinder 104 contracts, the swing arm 102 connected to the output end of the sweeping disc lifting cylinder 104 moves upward, driving the sweeping discs 101 connected on both sides to move upward; by adjusting the sweeping disc 101 to move up and down, the sweeping disc 101 is made closer to the ground to avoid dust caused by the sweeping disc 101 being too far from the ground; in areas that do not need to be swept, the sweeping disc 101 can be lifted to reduce unnecessary energy consumption.

[0026] As a further preference of the present embodiment, the sweeping disc 101 is hinged to the swing arm 102, an opening and closing cylinder 105 is fixedly provided at the bottom of either side of the swing arm 102, an opening and closing pull plate 106 is hinged under the swing arm 102, one end of the opening and closing pull plate 106 is hinged to the output end of the opening and closing cylinder 105, and pull rods 107 are hinged to the inner side of the sweeping disc 101, and the other ends of the two pull rods 107 are hinged to the other end of the opening and closing pull plate 106.

[0027] From the above description, it can be known that by controlling the extension and retraction of the opening and closing cylinder 105, the opening and closing pull plate 106 rotates around the hinge point with the swing arm 102, thereby driving the sweeping discs 101 on both sides to open and close; when the opening and closing cylinder 105 is in a stretched state, the opening and closing pull plate 106 rotates counterclockwise, and the end of the opening and closing pull plate 106 moves away from the closing cylinder 105 toward the vehicle body 9, reducing the angle between the pull rods 107 on both sides, and the sweeping discs 101 on both sides rotate around the hinge point with the swing arm 102, thereby reducing the distance between the sweeping discs 101 on both sides, so that the sweeping discs 101 on both sides are in the same state. When the two sweeping discs 101 are close to each other during cleaning, the density of cleaning can be increased and the cleaning efficiency can be improved. When the opening and closing cylinder 105 is in a retracted state, the opening and closing pull plate 106 rotates clockwise, and one end of the opening and closing pull plate 106 moves away from the closing cylinder 105 in the direction away from the vehicle body 9, thereby increasing the angle between the pull rods 107 on both sides. The sweeping discs 101 on both sides rotate around the hinge points with the swing arms 102 respectively, thereby increasing the distance between the sweeping discs 101 on both sides, making the sweeping discs 101 on both sides farther away during cleaning, which can expand the cleaning coverage and improve the efficiency of a single cleaning.

[0028] As a further preference of this embodiment, a first spring 108 is connected between the swing arm fixing frame 103 and the swing arm 102, and a second spring 109 is connected between the swing arm 102 and the sweeping disc 101. When it is necessary to increase the distance between the sweeping discs 101 on both sides, the cylinder 105 only provides pulling force when the sweeping discs 101 are retracted, and does not provide pulling force when the sweeping discs 101 on both sides are opened. Therefore, the second spring 109 is required to provide outward pulling force.

[0029] From the above description, it can be seen that the sweeping disc 101 can adjust the opening and closing angle and the spacing according to different road conditions. By controlling the opening and closing cylinder 105, the spacing between the sweeping discs 101 can be adjusted, thereby changing the cleaning density. The spacing can be reduced in areas that require fine cleaning and increased in areas that require quick cleaning, thereby improving the adaptability and efficiency of cleaning and collecting garbage more effectively.

[0030] Embodiment 3 The suction nozzle assembly 2 includes an absorption chamber 201, a suction tube 202 is sealed and connected to the top of the absorption chamber 201, a front baffle 203 is rotatably connected to the front of the absorption chamber 201, a driven rod 204 is fixedly connected to the outer side of the front baffle 203, an upper baffle 212 is fixedly connected to the upper surface of the absorption chamber 201, the middle position of the driven rod 204 is rotatably connected to the upper baffle 212, a telescopic rod 205 is rotatably connected to the top of the absorption chamber 201, and the other end of the driven rod 204 is hinged to the output end of the telescopic rod 205.

[0031] From the above description, it can be seen that by controlling the extension and retraction of the telescopic rod 205, the driven rod 204 is driven to rotate, thereby controlling the opening and closing of the front baffle 203; when the telescopic rod 205 is retracted, the driven rod 204 rotates counterclockwise around the hinge point with the upper baffle 212, driving the front baffle 203 to rotate and open, at which time the garbage is sucked into the absorption chamber 201 and enters the garbage bin 6 through the suction cylinder 202.

[0032] As a further optimization of this embodiment, the vehicle-end controller determines the type of garbage on the road ahead through the signal input by the camera 3. In case of an industrial road section with a lot of sand and gravel, the telescopic rod 205 on the suction nozzle can be controlled by the vehicle-end controller to close the front baffle 203 to increase the suction force. In case of large and light garbage such as leaves, bottles and cans, the front baffle 203 can be opened to allow the light objects to smoothly enter the absorption chamber 201. If there are other obstacles, the vehicle will stop automatically and wait for manual takeover.

[0033] From the above description, it can be known that by controlling the extension and retraction of the telescopic rod 205, the opening and closing degree of the front baffle 203 can be controlled, so that the suction force of the vehicle can be maximized when facing different garbage roads.

[0034] As a further preference of this embodiment, the nozzle assembly 2 also includes a nozzle lifting cylinder 206 and a rotating shaft 207. A nozzle fixing frame 208 is symmetrically fixedly arranged at the bottom of the vehicle body 9. The two ends of the rotating shaft 207 are rotatably connected to the nozzle fixing frames 208 on both sides. A triangular seat 209 is fixedly arranged at the middle position of the rotating shaft 207. The output end of the nozzle lifting cylinder 206 is hinged to the triangular seat 209, and the fixed end of the nozzle lifting cylinder 206 is hinged to the bottom of the vehicle body 9. A V-shaped connecting frame 210 is fixedly connected to the rotating shaft 207, and a fixed connecting frame 211 is fixedly arranged on the top of the absorption chamber 201, and the top of the fixed connecting frame 211 is hinged to the V-shaped connecting frame 210.

[0035] From the above description, it can be known that by controlling the extension and retraction of the nozzle lifting cylinder 206, the rotating shaft 207 rotates around its own axis, driving one end of the V-shaped connecting frame 210 to rotate along with the rotating shaft 207, thereby driving the fixed connecting frame 211 hinged at the other end of the V-shaped connecting frame 210 to move up and down, thereby realizing the up and down movement of the nozzle assembly 2; when the nozzle lifting cylinder 206 is extended, the rotating shaft 207 is driven to rotate counterclockwise around the axis through the triangular seat 209, driving the V-shaped connecting frame 210 to rotate counterclockwise, so that the fixed connecting frame 211 moves upward, and the nozzle assembly 2 moves upward; when the nozzle lifting cylinder 206 is contracted, the rotating shaft 207 is driven to rotate clockwise around the axis through the triangular seat 209, driving the V-shaped connecting frame 210 to rotate clockwise, so that the fixed connecting frame 211 moves downward, thereby realizing the overall downward movement of the nozzle assembly 2.

[0036] Embodiment 4 The vehicle body 9 includes a cab 5 , in which a steering mechanism is arranged. The steering mechanism includes a wire-controlled steering wheel 501 , a steering wheel motor 502 and a steering wheel controller 503 . The steering wheel controller 503 is communicatively connected with the camera 3 and the laser radar 4 . The steering wheel controller 503 is electrically connected with the steering wheel motor 502 . The steering wheel motor 502 controls the steering of the wire-controlled steering wheel 501 .

[0037] From the above description, it can be seen that when the intelligent edge cleaning is turned on, if there is a lane line or a curb, the camera 3 can identify the curb or lane line on the road, and then the laser radar 4 can sense the distance between the vehicle and the curb or lane line, and transmit this signal to the vehicle-side controller to determine whether there is a lane line or curb in front of the vehicle. The vehicle-side controller then transmits the signal to the steering wheel controller 503 to control the steering wheel motor 502 to realize vehicle steering, and automatically steers the vehicle and the curb or lane line at the set edge cleaning distance through the wire-controlled steering wheel 501, so that the vehicle automatically cleans the edge; if there is no lane line or curb, the vehicle will automatically stop and wait for manual operation.

[0038] As a further preference of this embodiment, in addition to automatic steering during autonomous driving, the wire-controlled steering wheel 501 can also detect torque changes when the wire-controlled steering wheel 501 is turned by the manual driver, and control the steering wheel motor 502 to provide appropriate assistance.

[0039] As a further preference of this embodiment, the cab 5 includes basic facilities such as air conditioning, an intelligent central control screen, a start / stop button, an emergency stop button, and other working buttons.

[0040] As a further preference of this embodiment, the chassis of the vehicle body 9 adopts a PIX chassis, which has all the driving functions of the whole vehicle, including forward and reverse braking and steering, etc. Its steering can also be divided into three types: front-wheel steering, four-wheel steering and wedge steering. Front-wheel steering is the steering mode of ordinary vehicles; four-wheel steering is the opposite steering of the front and rear wheels, which can achieve small radius turning; wedge steering is the same direction steering of the front and rear wheels, which can achieve parallel steering.

[0041] From the above description, it can be seen that when traditional cleaning vehicles are working close to the edge, manual operation may result in low accuracy when cleaning, or the vehicle cannot get completely close to the edge of the road, which easily leaves dead corners and blind spots that cannot be cleaned. In addition, the sanitation driver needs to observe the rearview mirror to ensure that the sweeping brush is always in a state of close to the edge. In this way, the driver's attention will be distracted, and obstacles in front are easily ignored. In addition, observing the rearview mirror for a long time will also cause great fatigue to the sanitation driver, and there are great safety hazards in long-term operation. However, this application has the function of automatic close-to-the-edge cleaning, which can improve the efficiency of sanitation operations, reduce the workload of sanitation drivers, and improve the safety of sanitation operations.

[0042] Embodiment 5 A trash bin 6 and a clean water tank 7 are arranged in the vehicle body 9 . The clean water tank 7 is connected to a water supply pipe 701 . The trash bin 6 is connected to a trash bin suction port 601 . The trash bin suction port 601 is sealedly connected to the suction cylinder 202 .

[0043] When the vehicle is working, the fan evacuates the inside of the garbage bin 6 , and the suction cylinder 202 connects the absorption chamber 201 and the suction port 601 of the garbage bin, so that the garbage enters the garbage bin 6 along the suction cylinder 202 .

[0044] As a further preference of this embodiment, a float level switch is provided in the trash bin 6, a pressure level gauge is provided in the clean water tank 7, and an intelligent central control screen is also provided in the cab 5. The float level switch and the pressure level gauge are both communicatively connected to the intelligent central control screen. The amount of water in the clean water tank 7 and the remaining volume in the trash bin 6 can be seen through the intelligent central control screen in the cab 5.

[0045] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
