Description

Technical Field

[0001] The utility model relates to the technical field of sanitation vehicles, in particular to a tailgate structure of a garbage bin of a sanitation vehicle. Background Art

[0002] With the continuous development of urbanization and modernization, the contemporary society has an increasing demand for efficient and automated road cleaning equipment, and traditional manual cleaning is gradually being replaced by professional road cleaning vehicles. For cleaning vehicles operating on motor vehicle lanes, their structure is generally equipped with a rotatable and lifting box, and the dumping and discharge of garbage and sewage is achieved through the openable tailgate at the rear of the box.

[0003] For example, the patent with publication number CN219278450U discloses a rear door locking structure for a sanitation vehicle, which does not cover the entire vehicle. Since the arrangement of the tail sewage belt, pipelines, and electrical lines affects the appearance of the vehicle, and since these parts are exposed to the outside for a long time, it is necessary to strengthen the dust and water resistance of the parts.

[0004] At the same time, the patent with publication number CN219278450U relates to a small vehicle that uses a structural member to cover the rear of the box body and cover the entire tailgate. The device adopts a split structure for the cover and the box body tailgate; the cover and the box body tailgate are respectively driven by power telescopic rods to move independently.

[0005] However, the device adds a set of power telescopic rods and induction switches at the front and rear positions, which complicates the structure and control logic. The existence of these newly added structures makes it difficult and costly to perform daily maintenance when the power telescopic rods and parts of the tailgate itself and the power telescopic rods and parts of the cover fail, such as when a power failure occurs when the tailgate and the cover are closed. This makes the tailgate and the cover unable to be opened, making them impossible to disassemble and require destructive disassembly.

[0006] When dumping garbage or repairing the tailgate, the device needs to open the cover, cooperate with the sensor switch to release the tailgate opening and closing restriction, and then use the power telescopic rod to drive the tailgate to open; resulting in the time taken to complete the garbage dumping operation being nearly doubled, resulting in reduced operation efficiency;

[0007] At the same time, after the cover is lifted, the overall height and length of the vehicle increase during the box dumping operation, which increases the demand for working space and is not suitable for large road operation vehicles.

[0008] Based on this, the utility model designs a tailgate structure of a garbage bin of a sanitation vehicle to solve the above problems. Utility Model Content

[0009] In view of the above-mentioned shortcomings of the prior art, the utility model provides a tailgate structure of a garbage bin of a sanitation vehicle.

[0010] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0011] A tailgate structure of a garbage bin of a sanitation vehicle, comprising a bin body;

[0012] A first cover plate is fixedly mounted on the box body, the tailgate is rotatably mounted on the box body, a cover plate mounting assembly and a locking assembly are mounted on the box body and the tailgate; a linkage assembly is mounted on the tailgate; a second cover plate is fixedly mounted on the cover plate mounting assembly; a push rod is rotatably mounted on the box body, and an output end of the push rod is fixedly connected to the linkage assembly; the linkage assembly is fixedly connected to the locking assembly; an indicator and warning light are fixedly mounted on the first cover plate.

[0013] Furthermore, the cover plate mounting assembly includes a bracket, a fixing seat, a mounting seat and a connecting rod, the two brackets are symmetrically fixedly mounted on the upper side of the box body, the fixing seat is fixedly mounted on the lower side of the tailgate, the mounting seat is rotatably mounted on the bracket, the fixing seat is rotatably connected to one end of the connecting rod, and the other end of the connecting rod is rotatably connected to the mounting seat; the mounting seat is fixedly mounted on the second cover plate.

[0014] Furthermore, two fixing seats are provided, and the two fixing seats are symmetrically distributed on the tailgate.

[0015] Furthermore, the linkage assembly includes a connecting assembly and a limiting assembly, the connecting assembly is installed on the output end of the push rod, and the limiting assembly is installed on the tailgate.

[0016] Furthermore, the limiting assembly includes a mounting frame and a limiting slot, the mounting frame is fixedly mounted on the tailgate, and the limiting slots are symmetrically provided on both sides of the mounting frame;

[0017] Furthermore, the connecting assembly includes a connecting block and a movable rod, wherein the movable rod is slidingly connected to the limiting groove, the movable rod is fixedly installed at one end of the connecting block, and the other end of the connecting block is fixedly connected to the output end of the push rod.

[0018] Furthermore, the locking assembly includes a mounting plate, a slot, an insertion rod and a guide block. The mounting plate is fixedly mounted on the lower side of the box body, a slot is formed on the mounting plate, one end of the insertion rod is plugged into the slot, and the other end of the insertion rod is fixedly connected to the movable rod; the insertion rod is limitedly slidably connected to the guide block, and the guide block is fixedly mounted on the tailgate.

[0019] Furthermore, a loading and unloading hole is formed on the second cover plate, and the loading and unloading hole is aligned with a mounting seat connected to the connecting rod.

[0020] The utility model has the following technical effects:

[0021] 1. The utility model has a simple overall structure. When the tailgate is lifted, the indicator and warning lights are still vertical to the ground and will not be blocked, making parking operations safer. The start push rod drives the locking assembly to move through the linkage assembly to release the lock between the box and the tailgate. Then the push rod drives the tailgate to rotate through the linkage assembly, so that the second cover plate is driven to rotate through the cover plate installation assembly while the tailgate is fully covered, and the tailgate and the second cover plate are opened. Thus, the tailgate is unlocked with one set of driving devices, and the tailgate and the cover plate are opened at the same time, which effectively improves the operation efficiency when dumping garbage.

[0022] 2. The movable push rod of the utility model drives the movable rod to move through the connecting block, and the movable rod slides vertically in the limiting groove under the limiting action of the limiting groove, thereby driving the insertion rod to move vertically, so that the insertion rod is separated from the slot and no longer hinders the movement of the tailgate, and the movable rod moves to the upper top of the limiting groove; the push rod continues to run, and the push rod drives the tailgate to rotate by driving the connecting block, the movable rod and the mounting frame; the rotation of the tailgate drives the rotation of the fixed seat, and the rotation of the fixed seat drives the second cover plate to move through the connecting rod and the mounting seat, and the second cover plate rotates around the connection point with the bracket; thereby, the starting push rod completes the unlocking of the tailgate and drives the tailgate and the second cover plate to rotate, thereby opening the tailgate and the second cover plate.

[0023] 3. In the present invention, when a power failure occurs when the tailgate and the cover are in a closed state, causing the tailgate and the second cover to be unable to open, the second cover can be removed from the mounting seat connected to the connecting rod through the loading and unloading hole, and the second cover can be rotated up with the connection point between the mounting seat and the bracket as the axis to open the second cover, thereby realizing the maintenance of the power failure without destructive dismantling.
