[0021] refer to Figures 1 to 3 As shown, this embodiment discloses a suction port device under the vehicle for dust removal and haze reduction cleaning vehicle, which is fixed under the vehicle body 1, forms an air duct by cooperating with components such as a fan and a suction pipe, and utilizes high-speed airflow to form negative pressure around the suction port, thereby sucking garbage into the suction nozzle and into the trash bin.
[0022] The vehicle bottom suction port device comprises: a first suction cup assembly 2, the first suction cup assembly 2 is arranged transversely along the vehicle body 1, and a first suction port 21 is provided at the bottom of the first suction cup assembly 2; The connecting rod mechanism 5 is connected between the two sides of the first suction cup assembly 2 and the vehicle body 1 to provide an oblique forward pulling force for the first suction cup assembly 2; The caster mechanism 3 is used to keep the first suction cup assembly 2 parallel to the ground, and includes a fixed caster 31 and a universal wheel 32. The universal wheel 32 is connected to the front side of the first suction cup assembly 2 to play a guiding role, and the fixed caster 31 is connected to the rear side of the first suction cup assembly 2; A lifting mechanism 4, connected between the two sides of the first suction cup assembly 2 and the vehicle body 1, and used for adjusting the height of the first suction cup assembly 2 from the ground; The second suction cup assembly 6 is hinged to the end of the first suction cup assembly 2 , and a second suction port 61 is provided at the bottom of the second suction cup assembly 6 , and is connected to the first suction cup assembly 2 through a flexible tube.
[0023] Specifically, refer to Figure 4 , Figure 5As shown, the first suction cup assembly 2 is rectangular, and its length is less than or equal to the width of the vehicle body 1. Two first suction ports 21 are arranged at intervals at the bottom of the first suction cup assembly 2, and the first suction ports 21 are connected to the fan through a pipeline. Among them, the number and shape of the first suction ports 21 can be selected according to actual needs. For example, the shape of the first suction ports 21 can be circular, rectangular or elliptical. A first rubber plate 22 surrounding the first suction port 21 is also provided at the bottom of the first suction cup assembly 2. The top of the first rubber plate 22 is fixed to the first suction cup assembly 2 by a pressure strip and screws. The first rubber plate 22 is the same width as the first suction cup assembly 2. When working, the first rubber plate 22 contacts the ground. With the cooperation of the fan, a negative pressure is formed around the first suction port 21 by using a high-speed airflow, so that the garbage is sucked into the first suction port 21 and enters the garbage bin, thereby improving the garbage cleaning effect.
[0024] In addition, the universal wheel 32 is connected to the front side of the first suction cup assembly 2 through a caster bracket, and the angle between the universal wheel 32 and the forward direction can be automatically adjusted according to the turning degree of the cleaning vehicle, thereby minimizing the wear of the universal wheel 32; the fixed caster 31 is connected to the rear side of the first suction cup assembly 2; the caster mechanism 3 ensures that the first suction cup assembly 2 can operate smoothly when the cleaning vehicle is running.
[0025] In some embodiments, the connecting rod mechanism 5 includes two connecting rods 51, and the two connecting rods 51 are respectively located at the left and right ends of the first suction cup assembly 2. One end of the connecting rod 51 is fixed to the vehicle body 1 through a universal shaft 52, and the other end is connected to the first suction cup assembly 2 through the universal shaft 52, providing an oblique forward pulling force for the first suction cup assembly 2, driving the first suction cup assembly 2 to move synchronously with the cleaning vehicle. At the same time, the first suction cup assembly 2 has four degrees of freedom, up, down, left and right. When working, the first suction cup assembly 2 contacts the ground through the caster mechanism 3, and can maintain contact with the ground when operating on various complex ground surfaces such as undulating waves, tilts, single-point protrusions, depressions, etc., effectively reducing the phenomenon of cleaning omissions and improving the cleaning ability of the cleaning vehicle.
[0026] In some embodiments, the lifting mechanism 4 is in two groups, which are fixed on both sides of the vehicle body 1, respectively, and include a lifting push rod 41 and a flexible connecting rod 42. Preferably, the flexible connecting rod 42 is a chain ring. The lifting push rod 41 is fixed on the vehicle body 1 in an inverted manner by bolts, and the output end of the lifting push rod 41 is connected to the end of the first suction cup assembly 2 through the flexible connecting rod 42, providing an oblique upward pulling force for the first suction cup assembly 2. When working, the operator controls the output end of the lifting push rod 41 to extend downward through the control system, so that the first suction cup assembly 2 can fit the ground. At the same time, the flexible connecting rod 42 plays a suspension function, and the first suction cup assembly 2 can realize the floating function under the action of the connecting rod mechanism 5; when canceling the operation, the operator controls the output end of the lifting push rod 41 to retract upward through the control system, and lifts the first suction cup assembly 2 upward, thereby improving the passability of the cleaning vehicle.
[0027] In some embodiments, reference Figure 4 As shown, the underbody suction port device also includes: a driving mechanism 7, connected between the second suction cup assembly 6 and the first suction cup assembly 2, for adjusting the relative angle between the second suction cup assembly 6 and the first suction cup assembly 2. Specifically, the driving mechanism 7 includes an electric push rod 72 and a flexible rope 73, preferably, the flexible rope 73 is a plastic-coated steel wire. The electric push rod 72 is fixed to the first suction cup assembly 2 by a U-shaped fixing plate 75 and bolts, the electric push rod 72 is electrically connected to the control system, and at the same time, the output end of the electric push rod 72 is connected to the second suction cup assembly 6 by a flexible rope 73, for applying a pulling force for backward rotation to the second suction cup assembly 6. The driving mechanism 7 also includes an elastic element 71, preferably, the elastic element 71 is a spring, and the elastic element 71 is fixed between the front end of the second suction cup assembly 6 and the first suction cup assembly 2, for applying a reset pulling force for forward rotation to the second suction cup assembly 6.
[0028] When the vacuuming width of the cleaning vehicle needs to be increased, the operator controls the output end of the electric push rod 72 to extend forward through the control system, and under the reset pulling force of the elastic element 71, the second suction cup assembly 6 rotates forward around the hinge between the second suction cup assembly 6 and the first suction cup assembly 2. When the output end of the electric push rod 72 is extended to the longest state, the second suction cup assembly 6 rotates to be in the same straight line with the first suction cup assembly 2, and under the combined action of the reset pulling force of the elastic element 71 and the pulling force of the electric push rod 72, the second suction cup assembly 6 can remain in the same straight line with the first suction cup assembly 2. Thereby increasing the vacuuming width of the cleaning vehicle and improving the cleaning efficiency of the cleaning vehicle.
[0029] When there is no need to increase the suction width of the cleaning vehicle, the operator controls the output end of the electric push rod 72 to retract backwards through the control system, and pulls the second suction cup assembly 6 to rotate backwards around the hinge between the second suction cup assembly 6 and the first suction cup assembly 2 through the flexible rope 73. When the output end of the electric push rod 72 is retracted to the shortest state, the second suction cup assembly 6 is folded behind the first suction cup assembly 2, thereby improving the passability of the cleaning vehicle.
[0030] In some embodiments, reference Figure 5 As shown, the second suction cup assembly 6 is provided with a second rubber plate 62 surrounding the second suction port 61 at the bottom, and the top of the second rubber plate 62 is fixed to the second suction cup assembly 6 by means of a pressure strip and screws, and the second rubber plate 62 is as wide as the second suction cup assembly 6. When working, the second rubber plate 62 contacts the ground, and with the cooperation of the fan, a negative pressure is formed around the second suction port 61 by using a high-speed airflow, so that the garbage is sucked into the second suction port 61 and enters the garbage bin, thereby improving the garbage cleaning effect.
[0031] In some embodiments, the second suction cup assembly 6 is hinged to the first suction cup assembly 2 via a V-shaped rotating hinge 74, and the electric push rod 72 is connected to the V-shaped rotating hinge 74 via a flexible rope 73 to drive the second suction cup assembly 6 to rotate in a horizontal direction relative to the first suction cup assembly 2.
[0032] In some embodiments, the end of the second suction cup assembly 6 away from the first suction cup assembly 2 is provided with a corner wheel 63 that can rotate in the horizontal direction. When encountering an obstacle, the corner wheel 63 contacts the obstacle and drives the second suction cup assembly 6 to rotate backward around the hinge between the second suction cup assembly 6 and the first suction cup assembly 2 to avoid the obstacle. At this time, the corner wheel 63 converts the collision sliding friction between the first suction cup assembly 2 and the obstacle into rolling friction, thereby reducing the damage to the first suction cup assembly 2 caused by the collision with the obstacle. At the same time, the spring plays a buffering role between the first suction cup assembly 2 and the second suction cup assembly 6, further reducing the damage to the first suction cup assembly 2 caused by the collision with the obstacle.
[0033] In some embodiments, the undercarriage suction port device also includes an obstacle recognition system. When the second suction cup assembly 6 encounters an obstacle during operation, the control system controls the output end of the electric push rod 72 to retract backwards, and pulls the second suction cup assembly 6 backwards around the hinge point through the flexible rope 73, and folds the second suction cup assembly 6 to the rear of the first suction cup assembly 2, thereby improving the passability of the cleaning vehicle. After passing the obstacle, the control system controls the output end of the electric push rod 72 to extend forward, and under the reset tension of the elastic element 71, the second suction cup assembly 6 rotates forward around the hinge point to restore the original working state. The undercarriage suction port device of this embodiment not only expands the suction and picking width, can effectively clean the root of the curb stone, but also improves the safety of the operating equipment.

Those skilled in the art should understand that the present application is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present application. Without departing from the spirit and scope of the present application, the present application may have various changes and improvements, which fall within the scope of the present application to be protected.
