[0002] With the rapid development of globalization and e-commerce, the logistics industry has experienced unprecedented growth. In this context, the speed and efficiency of logistics distribution are no longer simply operational indicators, but have become one of the key competitive forces in modern business operations. Therefore, continuously improving the speed and efficiency of logistics distribution has become an important task that cannot be ignored in modern business operations.

[0003] A logistics vehicle unloading connecting device is disclosed in Chinese Utility Model Patent No. CN212923635U. Through the cooperation of the first bearing plate, the second bearing plate and the hydraulic cylinder, the effective communication between the platform and the carriages of different heights is realized, and the loading and unloading speed and efficiency of the logistics vehicle are significantly improved. Although the device provides a convenient channel for loading and unloading goods, if the goods are not properly fixed or stacked during the loading and unloading process on the first bearing plate and the second bearing plate, they are likely to slide or collide under the influence of external forces.

[0004] Therefore, the present application provides an automatic loading and unloading docking equipment for a logistics vehicle to solve the above problems. CONTENT OF THE UTILITY MODEL

[0005] The present application provides an automatic loading and unloading docking equipment for a logistics vehicle, which aims to solve the problem that the existing unloading connecting device improves the loading and unloading efficiency, but the goods are not properly fixed or stacked, and are prone to sliding or collision accidents under the influence of external forces.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solution: an automatic loading and unloading docking equipment for a logistics vehicle, comprising a support seat, a lifting seat longitudinally moving in the support seat, three groups of fixedly arranged roller conveyor belts on the lifting seat and spaced apart, a fork frame symmetrically arranged on the support seat and respectively located between the three groups of roller conveyor belts for lifting goods, and a driving structure arranged on the lifting seat for lifting the lifting seat and moving the fork frame.

[0007] The docking equipment also comprises a protective fence symmetrically fixed on the lifting seat and located on both sides of the three groups of roller conveyors, an air bag fixed on the protective fence for preventing the goods from colliding, and an inflation assembly arranged on the support seat and connected with the fork frame for inflating and deflating the air bag; through the driving structure, the lifting seat and the roller conveyors can be lifted synchronously, and the fork frame can also automatically dock with the goods and move, which greatly reduces the time and labor of manual operation, significantly improves the overall loading and unloading efficiency, and effectively reduces the sliding or toppling of the goods during loading and unloading through the arrangement of the protective fence, thereby increasing the safety. In addition, the introduction of the air bag further enhances the protection of the goods. When the fork frame is used to move the goods on the support seat to the logistics vehicle, the inflation assembly can deflate the air bag to avoid hindering the goods. When the fork frame is used to lift the goods on the logistics vehicle and move back to the support seat, the inflation assembly can inflate the air bag to provide additional protection for the goods.

[0008] Preferably, in order to realize the lifting of the lifting seat, the driving structure comprises a first lead screw longitudinally penetrating the lifting seat and rotationally connected to the support seat at a position corresponding to the fork frame, and a motor fixedly arranged at the bottom end of the support seat for driving the first lead screw to rotate, and the lifting seat is screw-connected with the first lead screw. Through the rotation of the first lead screw driven by the motor, the lifting seat can be smoothly lifted due to the screw connection between the lifting seat and the first lead screw. This design is simple, efficient and easy to control.

[0009] Preferably, in order to realize the synchronous movement of the fork frame, the driving structure further comprises a transmission structure arranged in the support seat and connected with the top end of the first lead screw for moving the fork frame. The design of the transmission structure ensures the synchronization of the lifting of the lifting seat and the movement of the fork frame, thereby improving the coordination and efficiency of the loading and unloading operation.

This design can effectively transmit the rotating power of the first lead screw to the second lead screw, and the structure is compact, easy to install and maintain.

[0011] Preferably, in order to ensure the movement of the fork to dock with the goods on the logistics vehicle, a moving wheel is rotatably connected to the ground at the end of the fork away from the sliding block; the moving wheel enables the fork to move easily on the logistics vehicle, making it more convenient to dock with the goods or load the goods onto the logistics vehicle.

[0012] Preferably, in order to ensure the stability of the fork carrying the goods, anti-skid lines are linearly arranged on the top surface of the fork; the anti-skid lines increase the friction between the top surface of the fork and the goods, reducing the sliding or toppling of the goods during loading and unloading, and improving the safety of the operation.

[0013] Preferably, in order to realize the expansion and contraction of the air bag, the inflation assembly comprises a cylinder fixedly arranged in the support seat away from the fixed frame, a piston moving transversely in the cylinder, a push rod penetrating the end of the cylinder away from the support seat and fixedly connected with the piston, an L-shaped connecting plate fixedly connected with the end of the push rod away from the piston and fixedly connected with the end of the fork close to the sliding block, a hose fixedly arranged in the support seat and fixedly connected with the end of the cylinder away from the push rod, and an air inlet pipe fixedly arranged in the lifting seat and in communication with the hose and the air bag at both ends; the push rod is slidingly connected to the cylinder; the fixed connection of the push rod and the L-shaped connecting plate ensures that the piston can move in the cylinder when the fork moves, thereby realizing the automatic inflation and deflation of the air bag; this design improves the automation of the equipment and reduces the complexity of manual operation.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] This embodiment provides an automated loading and unloading docking equipment for logistics vehicles, such as... Figures 1-4 As shown, the docking equipment includes a support base 1, a lifting base 2 that moves longitudinally within the support base 1, three sets of roller conveyor belts 3 fixedly mounted on the lifting base 2 and spaced apart, forks 4 symmetrically mounted on the support base 1 and located between the three sets of roller conveyor belts 3 for lifting goods, and a drive structure 5 for raising and lowering the lifting base 2 and moving the forks 4; the docking equipment also includes guardrails 6 symmetrically fixedly mounted on the lifting base 2 and located on both sides of the three sets of roller conveyor belts 3, airbags 7 fixedly mounted on the guardrails 6 for preventing goods from colliding, and an inflation assembly 8 mounted on the support base 1 and connected to the forks 4 for inflating and contracting the airbags 7.

[0031] It needs to be explained that the roller conveyor 3 is the prior art, which mainly moves the articles forward on the conveyor through the rotation of the rollers, which are usually driven by a motor or other power device to produce continuous rotary motion. When the articles are placed on the conveyor, they are affected by the friction of the roller surface, thereby being driven forward.

[0032] In use, when used for unloading goods, the driving structure 5 drives the fork frame 4 to move outward to the logistics vehicle and inserts it into the bottom of the goods, at the same time the lifting seat 2 also drives the roller conveyor 3 to descend synchronously, then the driving structure 5 is started again to move the fork frame 4 back, at this time the fork frame 4 will lift the goods and drive the goods to move synchronously to the support seat 1, however, at the same time when the fork frame 4 moves back to the support seat 1, the lifting seat 2 also drives the roller conveyor 3 to rise synchronously, when the fork frame 4 drives the goods to move completely to the support seat 1, the roller conveyor 3 also synchronously lifts the goods on the fork frame 4, in the process of lifting, the guardrail 6 can protect the goods, finally the roller conveyor 3 is started again to convey the lifted goods to the desired position, and because the inflatable assembly 8 is connected with the fork frame 4, therefore, at the same time when the fork frame 4 moves back to the support seat 1, the inflatable assembly 8 can inflate the air bag 7 on the guardrail 6 synchronously to ensure the protection of the goods in the process of lifting and conveying on the roller conveyor 3, if the goods collide with the guardrail 6, the air bag 7 will play a buffering role to protect the goods from being damaged; when used for loading goods, after the goods are conveyed to the roller conveyor 3, they are conveyed to above the fork frame 4 through the roller conveyor 3, and the conveying of the roller conveyor 3 is paused, then the driving structure 5 is started to drive the roller conveyor 3 to descend, at this time the goods on the roller conveyor 3 will descend with the roller conveyor 3 to the fork frame 4, at the same time the fork frame 4 will move outward and approach the logistics vehicle, after the goods descend to the fork frame 4, the roller conveyor 3 will continue to descend, at the same time the fork frame 4 will continue to move outward and synchronously lift the goods to slowly move close to the logistics vehicle, finally the goods are taken off from the fork frame 4, which can be loaded on the logistics vehicle, similarly, when the fork frame 4 lifts the goods to move to the logistics vehicle, the inflatable assembly 8 will make the air bag 7 shrink with the movement of the fork frame 4, so that the goods on the fork frame 4 can smoothly pass between the two guardrails 6.

[0033] Specifically, the driving structure 5 includes a first lead screw 51 longitudinally penetrating the lifting seat 2 and rotationally connected to the support seat 1 at a position corresponding to the fork frame 4, and a motor 52 fixedly arranged at the bottom end of the support seat 1 for driving the first lead screw 51 to rotate, and the lifting seat 2 is screwed with the first lead screw 51;

[0034] When the roller conveyor 3 needs to be lifted, the motor 52 is started, at this time, the output shaft of the motor 52 drives the first lead screw 51 to rotate, because the first lead screw 51 is connected with the lifting seat 2 by screwing, so the rotation of the first lead screw 51 is converted into the linear motion of the lifting seat 2, with the rotation of the motor 52, the lifting seat 2 moves up and down along the axis direction of the first lead screw 51, so the lifting seat 2 synchronously drives the roller conveyor 3 to lift.

[0035] Further, the driving structure 5 further comprises a transmission structure 53 arranged in the support seat 1 and connected with the top end of the first lead screw 51 for moving the fork frame 4, the transmission structure 53 comprises a fixed frame 531 fixedly arranged in the support seat 1 and located between the fork frame 4 and the lifting seat 2, a sliding groove 532 opened in the fixed frame 531 close to the fork frame 4, a sliding block 533 slidingly connected in the sliding groove 532 and fixedly connected with one end of the bottom surface of the fork frame 4, a second lead screw 534 rotatably connected in the sliding groove 532 and screw-connected with the sliding block 533, a connecting bevel gear 535 fixedly sleeved on the top end of the first lead screw 51 and rotatably connected in the fixed frame 531, and a transmission bevel gear 536 fixedly sleeved on the second lead screw 534 and engaged with the connecting bevel gear 535, the top end of the first lead screw 51 penetrates through the fixed frame 531 and is rotatably connected in the fixed frame 531;

[0036] When the motor 52 drives the first lead screw 51 to rotate and drives the lifting seat 2 and the roller conveyor 3 to lift, because the top end of the first lead screw 51 is connected with the connecting bevel gear 535, and the connecting bevel gear 535 is engaged with the transmission bevel gear 536 on the second lead screw 534, so the rotation of the fixed frame 531 synchronously drives the second lead screw 534 to rotate, when the second lead screw 534 rotates, the sliding block 533 screw-connected therewith slides in the sliding groove 532, because the sliding block 533 is fixedly connected with one end of the bottom surface of the fork frame 4, so the sliding of the sliding block 533 drives the fork frame 4 to move horizontally, thereby the lifting of the roller conveyor 3 and the movement of the fork frame 4 can be cooperated during the loading and unloading process.

[0037] Among them, in order to ensure the movement of the fork frame 4 on the logistics vehicle and the goods, the ground on the side away from the sliding block 533 of the fork frame 4 is rotatably connected with a moving wheel 41; the design of the moving wheel 41 makes the fork frame 4 move outward to the logistics vehicle, and the fork frame 4 can easily move on the logistics vehicle and dock with the goods or load the goods on the logistics vehicle more conveniently.

[0038] In addition, in order to ensure the stability of the fork frame 4 carrying the goods, the top surface of the fork frame 4 is fixedly provided with anti-skid lines 42 arranged in a linear array; the design of the anti-skid lines 42 increases the friction between the top surface of the fork frame 4 and the goods, reduces the sliding or toppling of the fork frame 4 lifting the goods during the loading and unloading process, and improves the safety of the operation.

[0039] Further, the inflating assembly 8 comprises a cylinder 81 fixedly arranged in the support base 1 away from the side of the fixing frame 531, a piston 82 moving laterally in the cylinder 81, a push rod 83 penetrating through the cylinder 81 away from the support base 1 and fixedly connected with the piston 82, an L-shaped connecting plate 84 fixedly connected with the push rod 83 away from the piston 82 and fixedly connected with the end of the fork frame 4 close to the sliding block 533, a hose 85 arranged in the support base 1 and fixedly connected with the cylinder 81 away from the push rod 83, and an air inlet pipe 86 fixedly arranged in the lifting base 2 and communicated with the hose 85 and the air bag 7 respectively, and the push rod 83 is slidingly connected with the cylinder 81;

[0040] When the motor 52 is started and the rotating power of the first lead screw 51 is transmitted to the second lead screw 534 through the transmission structure 53 to make the fork frame 4 move horizontally, the fork frame 4 will synchronously drive the L-shaped connecting plate 84 connected thereto to move, since the L-shaped connecting plate 84 is connected with the push rod 83, and the push rod 83 is connected with the piston 82, therefore, when the L-shaped connecting plate 84 moves, the push rod 83 will synchronously push the piston 82 to move, when the push rod 83 pushes the piston 82 to move in the cylinder 81 to the side close to the hose 85, the piston 82 will compress the gas in the cylinder 81 to reduce the volume and increase the pressure, at this time, the compressed gas is transported to the air bag 7 through the hose 85 and the air inlet pipe 86 to make the air bag 7 expand, on the contrary, when the piston 82 moves to the other end away from the hose 85, the volume of the gas in the cylinder 81 increases and the pressure decreases, the gas in the air bag 7 will flow back to the cylinder 81 through the air inlet pipe 86 and the hose 85 to deflate the air bag 7 and make the air bag 7 contract.

[0041] The above merely describes the preferred embodiments of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can make equivalent substitution or change according to the technical solution and concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
