Description

Technical Field

[0001] This invention relates to the field of tricycle carriage technology, and more specifically to a tricycle carriage structure. Background Technology

[0002] Tricycles, with their simple structure, low manufacturing cost, high carrying capacity, and flexible steering, are widely used in scenarios such as agricultural production material transportation, short-distance urban and rural logistics distribution, and daily small-volume cargo transportation. Currently, most common tricycles use flat metal or corrugated steel floorboards, which have a flat and wear-resistant load-bearing surface and can adapt to the loading needs of various types of goods.

[0003] However, when loading or moving large box-shaped or bagged goods, existing tricycles have sliding friction between the box-shaped or bagged goods and the tricycle, which can easily damage the bottom of the goods and make it inconvenient to push the goods to move. Summary of the Invention

[0004] In view of the above-mentioned shortcomings in the prior art, the present invention provides a tricycle carriage structure to solve the problem that when loading or moving large box-shaped or bagged goods, there is sliding friction between the box-shaped or bagged goods and the carriage, which can easily damage the bottom of the goods.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A three-wheeled vehicle carriage structure includes a carriage body, the carriage body including a floor plate and a backrest fixedly installed on the floor plate, side plates fixedly installed on both sides of the floor plate, and a support plate fixedly installed between the side plates. The surface of the support plate is uniformly provided with guide components. With this structure, goods can be guided into the carriage, reducing the possibility of sliding friction between the goods and the support plate, thereby reducing the possibility of damage to the bottom of the goods.

[0006] Furthermore, the guiding assembly includes guide frames evenly arranged on the support plate, and guide rollers are rotatably installed inside the guide frames, thereby reducing the possibility of sliding friction between the goods and the bottom plate, thus reducing the possibility of damage to the bottom of the goods, and facilitating the movement of the goods.

[0007] Furthermore, the top surface of the support plate is uniformly provided with through grooves, the bottom surface of the guide frame is symmetrically and fixedly provided with push-pull blocks, and a receiving cavity is formed between the bottom plate and the support plate; A fixed frame is uniformly fixedly installed on the bottom surface of the receiving cavity. A push-pull motor is fixedly installed inside the fixed frame. Both ends of the push-pull motor are fixedly connected to screws. The other end of the screw is rotatably connected to the side wall of the fixed frame. A sliding block is threadedly connected to the outside of the screw. The sliding block is slidably connected to the fixed frame. A push-pull groove is opened on the top surface of the sliding block. The push-pull block abuts against the push-pull groove. This allows the guide component to be lowered according to actual needs, reserving more space for storing goods.

[0008] Furthermore, the bottom surface of the push-pull block is provided with a first inclined surface, and the push-pull groove is provided with a second inclined surface. The first inclined surface and the second inclined surface are adapted to each other, thereby driving the guide component to rise or fall, which facilitates mode switching.

[0009] Furthermore, the side of the through groove has an installation groove, and a rotating shaft is rotatably installed on the end face of the installation groove. A shielding roll is fixedly connected to the outside of the rotating shaft. A guide groove is opened on the end face of the through groove, and the end of the shielding roll can slide along the guide groove. A drive assembly is connected to the other end of the rotating shaft. Thus, after the guide assembly is lowered, the through groove can be closed, reducing the possibility of external dust entering the through groove.

[0010] Furthermore, a bevel gear is fixedly connected to the end of the rotating shaft, and a cavity is opened inside the support plate. The driving assembly includes a driving motor fixedly installed on the end face of the cavity. A driving rod is fixedly connected to the output end of the driving motor. The other end of the driving rod is rotatably connected to the end face of the cavity. Transmission gears are evenly fixedly installed on the driving rod. The transmission gears and bevel gears correspond one-to-one and mesh with each other, thereby simultaneously driving the shielding roll and controlling the opening and closing of the through slot.

[0011] Furthermore, a baffle is rotatably connected to the end face of the support plate, thereby reducing the possibility of goods slipping off.

[0012] Furthermore, the side plate has a groove on its end face, and the bottom plate is rotatably connected to an adjustment plate. A winding motor is fixedly installed in the groove, and the output end of the winding motor is hinged to a hinge. The other end of the hinge is hinged to the surface of the adjustment plate, thereby supporting the baffle and reducing the burden on the baffle. Attached Figure Description

Detailed Implementation

[0014] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0016] Example 1: like Figures 1-4As shown, a tricycle carriage structure of the present invention includes a carriage body 1, which includes a bottom plate 101 and a backrest 102 fixedly installed on the bottom plate 101. Side plates 103 are fixedly installed on both sides of the bottom plate 101, and a support plate 104 is fixedly installed between the side plates 103. Guide components 2 are evenly arranged on the surface of the support plate 104. The guide components 2 include guide frames 201 evenly arranged on the support plate 104. Guide rollers 202 are rotatably installed inside the guide frames 201. Specifically, when loading and unloading large box-shaped or bagged goods, the guide rollers 202 reduce the sliding friction between the goods and the support plate 104, thereby reducing the possibility of damage to the bottom surface of the goods, and at the same time facilitating the pushing of goods into the carriage body 1.

[0017] A baffle 601 is rotatably connected to the end face of the support plate 104, a groove 602 is opened on the end face of the side plate 103, and an adjusting plate 603 is rotatably connected to the end face of the bottom plate 101. A winding motor 604 is fixedly installed in the groove 602, and a hinge 605 is hinged to the output end of the winding motor 604. The other end of the hinge 605 is hinged to the surface of the adjusting plate 603. Specifically, during the loading and unloading of goods, the baffle 601 is supported by the adjusting plate 603 to facilitate the entry of goods into the main body 1 of the carriage. At the same time, the angle of the baffle 601 can be adjusted by the adjusting plate 603 to meet different actual needs.

[0018] Example 2: like Figures 1-4 As shown, the other features of this embodiment are the same as those of Embodiment 1, except that: The top surface of the support plate 104 has uniformly opened through grooves 203, and the bottom surface of the guide frame 201 is symmetrically and fixedly installed with push-pull blocks 204. A receiving cavity 3 is formed between the bottom plate 101 and the support plate 104. A fixed frame 301 is uniformly fixedly installed on the bottom surface of the receiving cavity 3. A push-pull motor 302 is fixedly installed inside the fixed frame 301. Both ends of the push-pull motor 302 are fixedly connected to screws 303. The other end of the screws 303 is rotatably connected to the side wall of the fixed frame 301. A sliding block 304 is threadedly connected to the outside of the screws 303. The sliding block 304 is slidably connected to the fixed frame 301. A push-pull groove 305 is opened on the top surface of the sliding block 304. The push-pull block 304 abuts against the push-pull groove 305. Specifically, the bottom surface of the push-pull block 204 is provided with a first inclined surface 205, and the push-pull groove 305 is provided with a second inclined surface 306, and the first inclined surface 205 and the second inclined surface 306 are compatible with each other; When the guide component 2 needs to rise or fall, the push-pull motor 302 is turned on, which drives the screw 303 to rotate. The outer side of the screw 303 is threaded with a sliding block 304, which drives the sliding block 304 to slide along the fixed frame 301. When the sliding block 304 slides toward the push-pull motor 302, the sliding block 304 pushes the push-pull block 204 to move toward the push-pull motor 302 and start to rise, thus driving the guide component 2 to rise. Similarly, when the sliding block 304 slides away from the push-pull motor 302, the sliding block 304 pushes the push-pull block 204 to move away from the push-pull motor 302 and begin to descend, driving the guide component 2 to descend. This allows for the selection of two modes: reserving more storage space or reducing the sliding friction between the goods and the carriage, depending on actual needs.

[0019] Example 3: like Figures 1-7 As shown, the other features of this embodiment are the same as those of Embodiment 2, except that: The side of the through groove 203 has a mounting groove 401. A rotating shaft 402 is rotatably mounted on the end face of the mounting groove 401. A shielding roll 403 is fixedly connected to the outside of the rotating shaft 402. A guide groove 404 is opened on the end face of the through groove 203. The end of the shielding roll 403 can slide along the guide groove 404. A drive assembly 5 is connected to the other end of the rotating shaft 402.

[0020] A bevel gear 501 is fixedly connected to the end of the rotating shaft 402. A cavity 502 is opened in the support plate 104. The drive assembly 5 includes a drive motor 503 fixedly installed on the end face of the cavity 502. A drive rod 504 is fixedly connected to the output end of the drive motor 503. The other end of the drive rod 504 is rotatably connected to the end face of the cavity 502. Transmission gears 505 are evenly fixedly installed on the drive rod 504. The transmission gears 505 and the bevel gears 501 correspond one-to-one and are meshed. Specifically, when it is necessary to reduce the sliding friction between the goods and the carriage, the drive motor 503 is turned on, which drives the drive rod 504 and the transmission gear 505 to rotate. The transmission gear 505 corresponds to and meshes with the bevel gear 501, thus driving the bevel gear 501 to start rotating. The bevel gear 501 drives the rotating shaft 402 to rotate, and the rotating shaft 402 starts to pull the shielding roll 403. The end of the shielding roll 403 starts to slide along the guide groove 404. After sliding a certain distance, the shielding roll 403 is rolled up on the outside of the rotating shaft 402, the through groove 203 is opened, and the guide component 2 can rise. Similarly, when more storage space needs to be reserved, the drive motor 503 is turned on, which drives the drive rod 504 and the transmission gear 505 to rotate in the opposite direction. This will cause the end of the shielding roll 403 to enter the guide groove 404, blocking the through groove 203 and closing the through groove 203.
