[0035] refer to Figures 1 to 3 As shown in the figure, this embodiment discloses a suction port device under the vehicle body 1 for a dust removal and haze reduction cleaning vehicle. It is fixed under the vehicle body 1 and forms an air duct by cooperating with components such as a fan and suction pipe. The high-speed airflow creates negative pressure around the suction port, thereby sucking the garbage into the suction nozzle and into the garbage bin.
[0036] The under-vehicle suction device includes: a first suction cup assembly 2, which is arranged laterally along the vehicle body 1, and a first suction port 21 is provided at the bottom of the first suction cup assembly 2;
[0037] The linkage mechanism 5 is connected between the two sides of the first suction cup assembly 2 and the vehicle body 1, providing a forward-angled pulling force to the first suction cup assembly 2;
[0038] The caster mechanism 3 is used to keep the first suction cup assembly 2 parallel to the ground. It includes a fixed caster 31 and a swivel caster 32. The swivel caster 32 is connected to the front side of the first suction cup assembly 2 and plays a guiding role. The fixed caster 31 is connected to the rear side of the first suction cup assembly 2.
[0039] The lifting mechanism 4 is connected between the two sides of the first suction cup assembly 2 and the vehicle body 1, and is used to adjust the height of the first suction cup assembly 2 off the ground.
[0040] The second suction cup assembly 6 is hinged to the end of the first suction cup assembly 2. The bottom of the second suction cup assembly 6 is provided with a second suction port 61, which is connected to the first suction cup assembly 2 through a flexible tube.
[0041] For details, please refer to Figure 4 , Figure 5 As shown, the first suction cup assembly 2 is rectangular, with its length less than or equal to the width of the vehicle body 1. The bottom of the first suction cup assembly 2 has two spaced-apart first suction ports 21, which are connected to a blower via pipes. 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. The bottom of the first suction cup assembly 2 also has a first rubber plate 22 surrounding the first suction ports 21. The top of the first rubber plate 22 is fixed to the first suction cup assembly 2 by pressure strips and screws. The first rubber plate 22 is the same width as the first suction cup assembly 2. During operation, the first rubber plate 22 contacts the ground. With the assistance of the blower, a negative pressure is created around the first suction ports 21 using high-speed airflow, thereby sucking garbage into the first suction ports 21 and into the garbage bin, improving the garbage cleaning effect.
[0042] In addition, the omnidirectional wheel 32 is connected to the front of the first suction cup assembly 2 via a caster bracket, and can automatically adjust the angle between the omnidirectional wheel 32 and the direction of travel according to the degree of turning of the cleaning vehicle, so as to minimize the wear of the omnidirectional wheel 32; the directional caster 31 is connected to the rear of the first suction cup assembly 2; the caster mechanism 3 ensures that the first suction cup assembly 2 can operate smoothly as the cleaning vehicle runs.
[0043] In some embodiments, the linkage mechanism 5 includes two links 51, located at the left and right ends of the first suction cup assembly 2, respectively. One end of each link 51 is fixed to the vehicle body 1 via a universal joint 52, and the other end is connected to the first suction cup assembly 2 via the universal joint 52, providing a forward-angled pulling force to the first suction cup assembly 2 and causing it to move synchronously with the cleaning vehicle. Simultaneously, this allows the first suction cup assembly 2 to have four degrees of freedom (up, down, left, and right). During operation, the first suction cup assembly 2 contacts the ground via the caster mechanism 3, maintaining contact with the ground even on complex surfaces such as undulating, inclined, single-point protrusions, and depressions, effectively reducing cleaning omissions and improving the cleaning vehicle's sweeping capabilities.
[0044] In some embodiments, the lifting mechanism 4 consists of two sets, fixed to both sides of the vehicle body 1, including a lifting push rod 41 and a flexible connecting rod 42. Preferably, the flexible connecting rod 42 is a chain link. The lifting push rod 41 is fixed to the vehicle body 1 with bolts in an inverted position. The output end of the lifting push rod 41 is connected to the end of the first suction cup assembly 2 via the flexible connecting rod 42, providing an upward pulling force to the first suction cup assembly 2. During operation, the operator controls the output end of the lifting push rod 41 to extend downwards via the control system, allowing the first suction cup assembly 2 to conform to the ground. Simultaneously, the flexible connecting rod 42 acts as a suspension mechanism, working together with the linkage mechanism 5 to enable the first suction cup assembly 2 to float. When the operation is canceled, the operator controls the output end of the lifting push rod 41 to retract upwards via the control system, lifting the first suction cup assembly 2 upwards, thereby improving the passability of the cleaning vehicle.
[0045] In some embodiments, reference Figure 4 As shown, the undercarriage suction device further includes a drive 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 drive 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. At the same time, the output end of the electric push rod 72 is connected to the second suction cup assembly 6 through the flexible rope 73, for applying a backward rotational pulling force to the second suction cup assembly 6. The drive mechanism 7 also includes an elastic element 71, preferably, the elastic element 71 is a spring. 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 forward rotational restoring pulling force to the second suction cup assembly 6.
[0046] When it is necessary to increase the suction width of the cleaning vehicle, the operator controls the output end of the electric push rod 72 to extend forward via the control system. Under the restoring pull of the elastic element 71, the second suction cup assembly 6 rotates forward around the hinge point 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 its longest position, the second suction cup assembly 6 rotates to be in a straight line with the first suction cup assembly 2. Under the combined action of the restoring pull of the elastic element 71 and the pull of the electric push rod 72, the second suction cup assembly 6 can maintain a straight line with the first suction cup assembly 2. This increases the suction width of the cleaning vehicle and improves its cleaning efficiency.
[0047] When it is not necessary to increase the suction width of the cleaning vehicle, the operator controls the output end of the electric push rod 72 to retract backward via the control system. This causes the second suction cup assembly 6 to rotate backward around the hinge point between the second suction cup assembly 6 and the first suction cup assembly 2 via the flexible rope 73. When the output end of the electric push rod 72 retracts to its shortest state, the second suction cup assembly 6 folds behind the first suction cup assembly 2, thereby improving the mobility of the cleaning vehicle.
[0048] In some embodiments, reference Figure 5 As shown, the bottom of the second suction cup assembly 6 is provided with a second rubber plate 62 surrounding the second suction port 61. The top of the second rubber plate 62 is fixed to the second suction cup assembly 6 by a pressure strip and screws. The second rubber plate 62 is the same width as the second suction cup assembly 6. During operation, the second rubber plate 62 contacts the ground. With the cooperation of the fan, a negative pressure is formed around the second suction port 61 by using high-speed airflow, thereby sucking the garbage into the second suction port 61 and into the garbage bin, improving the garbage cleaning effect.
[0049] In some embodiments, the second suction cup assembly 6 is hinged to the first suction cup assembly 2 via a V-shaped rotary hinge 74, and the electric push rod 72 is connected to the V-shaped rotary hinge 74 via a flexible rope 73 to drive the second suction cup assembly 6 to rotate relative to the first suction cup assembly 2 in the horizontal direction.
[0050] In some embodiments, the end of the second suction cup assembly 6 furthest from the first suction cup assembly 2 is provided with a horizontally rotatable corner wheel 63. When encountering an obstacle, the corner wheel 63 contacts the obstacle, causing the second suction cup assembly 6 to rotate backward around the hinge point 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 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 obstacle collision. At the same time, the spring acts as a buffer 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 obstacle collision.
[0051] In some embodiments, the under-vehicle suction device further 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 backward. A flexible rope 73 pulls the second suction cup assembly 6 backward around the hinge point, folding the second suction cup assembly 6 behind 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. Under the restoring force of the elastic element 71, the second suction cup assembly 6 rotates forward around the hinge point, returning to its original working state. The under-vehicle suction device of this embodiment not only expands the suction width, effectively cleaning the base of curb stones, but also improves the safety of the operating equipment.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
