Description

Technical Field

[0001] This utility model relates to the field of automotive technology, and in particular to a self-unloading mechanism for automobile cargo compartments. Background Technology

[0002] In modern life, various trucks are important means of transportation. The cargo boxes of these trucks often need to be equipped with self-dumping structures. Chinese patent document with publication number CN113335001A discloses a self-dumping cargo box applied to trailers.

[0003] However, in the above-mentioned technical solution, the connection between the truck body and the bottom frame is relatively small and the strength is weak during the self-unloading process. The support direction is unidirectional. The truck body and the cargo inside are heavy. Under the action of various forces, the truck body is prone to tilting or even deforming and collapsing. At the same time, the cargo inside the truck body is prone to getting stuck at the head of the truck body. Workers often need to climb into the truck body and use tools to assist in unloading. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as unidirectional support, easy jamming of goods, and the need for worker assistance in unloading, by proposing a self-unloading mechanism for automobile carriages.

[0038] With the above structure, the arc-shaped strip 9 and arc-shaped sleeve 8 can provide limiting support on both sides of the main body of the car body 1. When the main body of the car body 1 tilts to one side, the arc-shaped strip 9 and arc-shaped sleeve 8 can limit and correct it, forming a new supporting force. Moreover, through the movement of the unloading plate 14, the goods stuck inside the main body of the car body 1 can be loosened and unloaded automatically.

[0039] Please see Figure 2 The unloading mechanism includes an electric push rod 10, a hinge rod 11, a transmission frame 12, and an unloading rod 13. The output end of the electric push rod 10 is hinged to the bottom end of the hinge rod 11, and the top end of the hinge rod 11 is hinged to the surface of the transmission frame 12. The sliding hole of the transmission frame 12 is slidably connected to the protrusion on the surface of the unloading rod 13. The bottom end of the unloading rod 13 passes through the hole in the main body 1 of the automobile compartment and is bolted to the top of the unloading plate 14. When the power supply to the electric push rod 10 is turned on, the electric push rod 10 can drive the hinge rod 11 to move downward. The hinge rod 11 can drive the transmission frame 12 to rotate downward. The sliding hole of the transmission frame 12 can slide on the protrusion of the unloading rod 13 and drive the unloading rod 13 to move downward. The unloading rod 13 can drive the unloading plate 14 to move.

[0040] Please see Figure 2 The transmission box 15 is bolted to the middle of the top of the main body 1 of the car body. The right end of the transmission frame 12 is rotatably connected to the inside of the transmission box 15. The transmission frame 12 is rotatably set with the transmission box 15 through bearings to ensure the smooth rotation of the transmission frame 12.

The car body door is used to open the car body 1, and the movement of the unloading plate 14 can loosen the goods inside the car body 1.

[0044] Example 2

[0045] The difference between this embodiment and Embodiment 1 is that the electric actuator 10 and the hinge rod 11 are replaced with a rotary motor. The output end of the rotary motor is connected to the hole of the transmission frame 12, so that the rotary motor can drive the transmission frame 12 to rotate. However, the rotational resistance of the rotary motor is relatively large. Therefore, the preferred embodiment in this application is the electric actuator 10 and the hinge rod 11.

[0046] It should be noted that the specific models of hydraulic rod 6 and electric actuator 10 used should be selected by those skilled in the art. Furthermore, the hydraulic rod 6, electric actuator 10, and detection probe mentioned above are all existing technologies and will not be elaborated upon in this solution.

[0047] The working principle of this utility model is as follows: The frame 4 is fixed on the chassis of the truck. The truck body 1 is used to accommodate goods. The support frame 2 is responsible for supporting the truck body 1. The support frame 2 is rotatably set with the frame 4 through two structures: a rotating shaft 3 and a rotating seat 5. The hydraulic rod 6 is hydraulically controlled and can drive the truck body 1 to rotate through the beam 7 and the support frame 2. During the unloading process of the truck body 1, the sliding of the arc-shaped strip 9 and the arc-shaped sleeve 8 can limit and support both sides of the truck body 1, preventing the truck body 1 from tilting due to external forces. After body 1 is rotated downwards to a horizontal position, goods may easily get stuck inside the truck body 1 near the front of the truck during transportation. When self-unloading is required, the power of electric push rod 10 is turned on. Electric push rod 10 can drive hinge rod 11 to move downwards. Hinge rod 11 can drive transmission frame 12 to rotate downwards. The sliding hole of transmission frame 12 can slide on the protrusion of unloading rod 13 and drive unloading rod 13 to move downwards. Unloading rod 13 can drive unloading plate 14 to move. Unloading plate 14 moves inside truck body 1, which can loosen the goods stuck in truck body 1 and automatically unload them.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
