Abstract
Description
Technical Field
[0001] This utility model relates to the field of cargo vehicle technology, and in particular to a cargo vehicle with a buffer protection function. Background Technology
[0002] Warehouse trucks typically refer to specialized vehicles used for transporting and handling goods in warehousing and logistics scenarios. Their main function is to carry and unload goods within warehouses or during short-distance transportation. They come in various forms, but their core characteristics are high load-bearing capacity and structural design adapted to goods storage and handling. Some models are equipped with lifting and rotating functions to improve operational efficiency. Electric flatbed trucks are a type of warehouse truck.
[0003] In existing technologies, traditional warehouse trucks mostly use front bumper strips, single-sided springs, or other single-sided or one-way buffers, which can only cope with impacts from the front or side. When a diagonal collision occurs, such as a 45° angle impact with a shelf, the goods are prone to tipping over due to the combined forces from the lateral and longitudinal directions. Furthermore, the rigidly connected pallets (with the goods directly fixed to the vehicle body) have no sliding buffer space, and the impact energy is directly transferred to the goods, which is not conducive to the protection of the goods. Therefore, it is necessary to propose a warehouse truck with a buffer protection function to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a cargo vehicle with a buffer protection function.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A cargo vehicle with a buffer protection function includes a vehicle body. A seat frame and a control handle are fixedly installed on the top surface of the vehicle body. A PLC controller is fixedly installed on one side of the vehicle body. The vehicle also includes a buffer protection assembly disposed on the top surface of the vehicle body for buffering goods on the top surface of the vehicle body. The buffer protection assembly includes: a placement platform disposed on the top surface of the vehicle body; two fixed plates are fixedly installed on the top surface of the vehicle body; the top surface of each fixed plate has a T-shaped groove; two T-shaped plates are movably fitted inside the T-shaped groove; a fixed tube is fixedly installed on the top surface of each T-shaped plate; a sliding plate is movably fitted inside the fixed tube; and two circular grooves are formed on the top surface of the sliding plate. Two weight sensors are fixedly sleeved on the inner circular wall of the circular groove. The top surface of the weight sensors is fixedly installed on the placement platform. Several electromagnetic dampers are provided on the top surface of the vehicle body. A second fixed post is movably sleeved on the inner circular wall of the tail end of the electromagnetic damper. The second fixed post is fixedly installed on the vehicle body. A first fixed post is movably sleeved on the inner circular wall of the front end of the electromagnetic damper. A spring is movably sleeved on the outer circular wall of the telescopic rod of the electromagnetic damper. The first fixed post is fixedly installed on the inner top surface of the placement platform. The weight sensors and the electromagnetic dampers are electrically connected to the PLC controller. An impact buffer assembly is used to buffer the impact on the vehicle body.
[0007] As a further embodiment of this utility model, the impact buffer assembly includes: a plurality of connecting columns, which are respectively fixedly installed on the four outer sides of the vehicle body, and a support plate is provided on the outside of the vehicle body, the support plate being fixedly installed with the connecting columns.
[0008] As a further embodiment of this utility model, a rubber plate is fixedly installed on the side wall of the support plate, and a plurality of airbag strips are fixedly installed on the outside of the rubber plate.
[0009] As a further embodiment of this utility model, a number of straps are fixedly installed on the top surface of the placement platform.
[0010] As a further embodiment of this utility model, sliding grooves are respectively provided inside the T-shaped groove and on both sides of the inside of the fixed tube. Two sliding grooves are respectively provided on the bottom surface of the inside of the T-shaped groove and on the bottom surface of the inside of the fixed tube. Several spherical grooves are respectively provided on both sides and bottom of the T-shaped plate and on both sides and bottom of the sliding plate. A steel column is movably sleeved on the inner circular wall of the spherical groove.
[0011] As a further embodiment of this utility model, a limiting groove is provided on the top surface of the sliding plate, and a plurality of limiting posts are fixedly installed on the bottom surface of the placement platform, wherein the limiting posts are movably connected to the limiting groove.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. By using the coordinated design of the vehicle body, seat frame, control handle, placement platform, fixed plate, and T-slot, the system can effectively cushion and protect the goods. The coordinated use of the fixed plate, T-slot, fixed tube, sliding plate, and placement platform allows the placement platform to move in multiple directions. When the vehicle body collides with the shelf, the goods slide in multiple directions along the T-slot and fixed tube due to inertia, providing physical space for cushioning and preventing the impact energy from being directly transferred to the goods. This also prevents the goods from directly bearing the rigid impact of the vehicle body. The viscous resistance of the damper can suppress the sliding speed, and the elastic restoring force of the spring can prevent excessive displacement of the goods, effectively ensuring the safety of the goods. This system is quite practical.
[0014] 2. With the airbag strips and rubber plates in place, when the vehicle body collides with the shelf, the airbag strips and rubber plates work together to provide initial and secondary cushioning of the impact force, effectively reducing the impact force and protecting the vehicle body. The limit post is inserted into the limit groove, allowing the placement platform to move up and down. The limit groove restricts the lateral movement of the limit post and the placement platform.

[0027] Reference Figures 1-8A cargo vehicle with a buffer protection function includes a vehicle body 1. A seat frame 2 and a control handle 3 are fixedly installed on the top surface of the vehicle body 1. A PLC controller is fixedly installed on one side of the vehicle body 1. The vehicle also includes a buffer protection assembly, which is disposed on the top surface of the vehicle body 1 and used to buffer goods on the top surface of the vehicle body 1. The buffer protection assembly includes a placement platform 4, which is disposed on the top surface of the vehicle body 1. Two fixed plates 5 are fixedly installed on the top surface of the vehicle body 1. T-shaped grooves 6 are formed on the top surface of the fixed plates 5. Two T-shaped plates 7 are movably fitted inside the T-shaped grooves 6. Fixed pipes 8 are fixedly installed on the top surface of the T-shaped plates 7. Sliding plates 9 are movably fitted inside the fixed pipes 8. Two circular grooves are formed on the top surface of the sliding plates 9. Two circular grooves are fixedly fitted on the inner circular walls of the circular grooves. A weight sensor 10 is fixedly installed on its top surface to the placement platform 4. Several electromagnetic dampers 14 are provided on the top surface of the vehicle body 1. The electromagnetic dampers 14 are of model Bohai-C50-170C and have adjustable damping. A second fixed post 16 is movably sleeved on the inner circular wall of the tail end of the electromagnetic damper 14. The second fixed post 16 is fixedly installed on the vehicle body 1. A first fixed post 11 is movably sleeved on the inner circular wall of the front end of the electromagnetic damper 14. A spring 15 is movably sleeved on the outer circular wall of the telescopic rod of the electromagnetic damper 14. The first fixed post 11 is fixedly installed on the inner top surface of the placement platform 4. The weight sensor 10 and the electromagnetic dampers 14 are both electrically connected to the PLC controller. An impact buffer assembly is used to buffer the impact on the vehicle body 1.
[0028] In use, if the vehicle body 1 is accidentally involved in a collision or emergency braking, the goods on the top surface of the placement platform 4 will maintain their movement due to inertia, thereby pushing the placement platform 4 to move the sliding plate 9 laterally inside the fixed tube 8. The fixed tube 8 moves in front and behind the T-shaped groove 6 through the T-shaped plate 7. In this way, the placement platform 4 can move at multiple angles. Several electromagnetic dampers 14 pull the placement platform 4, and together with the spring 15, they buffer the fixed goods, suppress the movement of the goods, and thus buffer and protect the goods. At the same time, it can buffer impact forces from multiple angles, such as combined lateral and longitudinal forces.
[0029] In this embodiment, the impact buffer assembly includes: a plurality of connecting columns 22, which are fixedly installed on the four outer sides of the vehicle body 1; a support plate 24 is provided on the outside of the vehicle body 1, which is fixedly installed with the connecting columns 22; a rubber plate 23 is fixedly installed on the side wall of the support plate 24; a plurality of airbag strips 12 are fixedly installed on the outside of the rubber plate 23; a plurality of straps 13 are fixedly installed on the top surface of the placement platform 4; sliding grooves 17 are respectively opened on the inside of the T-shaped groove 6 and the inside of the fixed tube 8; two sliding grooves 17 are respectively opened on the bottom surface of the inside of the T-shaped groove 6 and the bottom surface of the inside of the fixed tube 8; a plurality of spherical grooves 18 are respectively opened on the sides and bottom surface of the T-shaped plate 7 and the sides and bottom surface of the sliding plate 9; steel columns 19 are movably sleeved on the inner circular wall of the spherical groove 18; a limiting groove 20 is opened on the top surface of the sliding plate 9; a plurality of limiting columns 21 are fixedly installed on the bottom surface of the placement platform 4, and the limiting columns 21 are movably sleeved with the limiting grooves 20.
[0030] In use, the airbag strip 12 and rubber plate 23 work together to provide initial and secondary cushioning of the impact force when the vehicle body 1 collides with the shelf or other equipment, effectively reducing the impact force and protecting the vehicle body 1. The limiting post 21, inserted into the limiting groove 20, allows the placement platform 4 to move vertically, while the limiting groove 20 restricts the lateral movement of the limiting post 21 and the placement platform 4.
[0031] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: When the user needs to transport goods through the set vehicle body 1, the user sits on the seat frame 2 and controls the vehicle body 1 to move by controlling the handle 3. The specific control method and control principle are existing technologies and will not be described in detail. Then, the vehicle body 1 is moved to the place of use, and then the goods are placed on the top surface of the placement platform 4, and then the straps 13 are used to tie and fix the goods together.
[0032] The weight of the goods is detected by several weight sensors 10, which in turn controls the damping of the electromagnetic dampers 14 (the damping is adjustable). The greater the weight, the greater the damping. The damping is so great that the goods will not sway significantly during normal movement, thus not affecting the normal movement of the vehicle body 1. The goods are moved by the vehicle body 1. When the vehicle body 1 accidentally collides or brakes suddenly, the goods on the top surface of the placement platform 4 maintain their moving trend due to inertia, thereby pushing the placement platform 4 to drive the sliding plate 9 to move laterally inside the fixed tube 8. The fixed tube 8 moves in front and behind the T-slot 6 through the T-shaped plate 7. In this way, the placement platform 4 can move at multiple angles. Several electromagnetic dampers 14 pull the placement platform 4, which, together with the spring 15, stabilizes the fixed goods. The system provides cushioning to suppress the movement of goods, thus protecting them. It can also buffer impacts from multiple angles, such as combined lateral and longitudinal forces, achieving a comprehensive cushioning effect. Through the coordinated use of the fixed plate 5, T-shaped plate 7, fixed tube 8, sliding plate 9, and placement platform 4, the placement platform 4 can move in multiple directions. When the vehicle collides with the shelf, the goods slide along the T-shaped groove 6 and fixed tube 8 due to inertia, providing physical space for cushioning and preventing the impact energy from being directly transferred to the goods. This avoids the goods directly bearing the rigid impact of the vehicle body. The viscous resistance of the damper suppresses the sliding speed, and the elastic restoring force of the spring 15 prevents excessive displacement of the goods, effectively ensuring their safety and making it quite practical.
[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. 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.
