[0026] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solutions of the present invention, and to facilitate its implementation.

[0027] It should be noted that in the following embodiments, the terms "first" and "second" do not represent an absolute distinction in structure and / or function, nor do they represent the order of execution, but are merely for the convenience of description.

[0028] like Figures 1 to 7 As shown, the present invention provides an intelligent container changing platform, including a platform body 3, a lifting rod 4 for lifting the container, and a lifting device disposed on the platform body 3 for controlling the lifting rod 4 to move up and down. Two platform bodies 3 are provided and the platform bodies 3 are movable, and the distance between the two platform bodies 3 is adjustable.

[0029] Specifically, such as Figure 1 As shown, the platform body 3 is movably mounted on the first guide rail 2. The first guide rail 2 is horizontally positioned, and two first guide rails 2 are arranged on the same straight line parallel to a first direction. The length direction of the first guide rail 2 is parallel to a second direction, both of which are horizontal and perpendicular. The first guide rail 2 guides the platform body 3. The platform body 3 is equipped with a traveling mechanism that generates a driving force to move the platform body 3. The platform body 3 can move linearly along the first guide rail 2, allowing adjustment of the distance between the two platform bodies 3 to meet the lifting requirements of vehicle cargo boxes of different widths. The width of the cargo box is parallel to the second direction. The first guide rail 2 ensures the stability and accuracy of the platform body 3 during movement. At least two lifting rods 4 are mounted on the platform body 3, all of which are on the same straight line parallel to the first direction. The lifting rods 4 are located below the cargo box and are used to contact the bottom surface of the cargo box. By adjusting the distance of the platform body 3 and the position of the lifting rod 4, it is possible to flexibly handle cargo boxes of different sizes, thereby improving loading and unloading efficiency and safety.

[0030] like Figure 2 As shown, the vehicle includes a chassis and a cargo box mounted on the chassis. The cargo box is detachably connected to the chassis and is a container used for loading goods.

[0031] Preferably, the lifting device includes a lifting mechanism and a reversing mechanism. The lifting mechanism is configured to control the lifting rod 4 to rise and fall. The reversing mechanism is configured to control the rotation of the lifting rod 4. The reversing mechanism is mounted on the lifting mechanism and controls the reversing mechanism and the lifting rod 4 to rise and fall synchronously. The reversing mechanism is connected to one lifting rod 4, which is horizontally positioned. The reversing mechanism controls the lifting rod 4 to switch between a retracted state and a working state. In the working state, the length direction of the lifting rod 4 is parallel to a second direction. At this time, the lifting rod 4 can cooperate with the lifting mechanism to lift the cargo box. After the reversing mechanism starts working, it controls the lifting rod 4 to rotate as necessary to adjust the direction or position of the lifting rod 4. Because the reversing mechanism is mounted on the lifting mechanism and controls the synchronous rise and fall of the two, the reversing mechanism can maintain a constant relative position with the lifting rod 4 while changing the direction of the lifting rod 4, thereby ensuring the stability and accuracy of the lifting process.

[0032] Preferably, the lifting mechanism mainly includes a support rod 6 and a lifting actuator connected to the support rod 6. The reversing mechanism is set on the support rod 6, the support rod 6 is set vertically, the lifting actuator is located inside the platform body 3, the support rod 6 extends upward to the outside of the platform body 3, and the lifting actuator is electrically connected to the control system.

[0033] In this embodiment of the invention, the lifting actuator is preferably a hydraulic cylinder, which is vertically arranged, and the lower end of the support rod 6 is fixedly connected to the piston rod of the hydraulic cylinder.

[0034] When the cargo box needs to be lifted, the lifting mechanism starts working, controlling the lifting rod 4 to move upward. When the lifting rod 4 reaches the required working position, it is in working condition, and the lifting rod 4 contacts the bottom surface of the cargo box; the lifting mechanism continues to control the lifting rod 4 to move upward, which can lift the cargo box upward and separate the cargo box from the vehicle chassis.

[0035] Preferably, the reversing mechanism mainly includes a motor connected to the lifting rod 4. The motor is vertically arranged and is used to control the rotation of the lifting rod 4. The rotation center line of the lifting rod 4 is a vertical line, and the motor is electrically connected to the control system.

[0036] Preferably, the support rod 6 has an internal cavity to accommodate the motor, and multiple ball bearings are arranged on the top of the support rod 6 to contact the lifting rod 4. All ball bearings are evenly distributed circumferentially around the rotation centerline of the lifting rod 4. This arrangement ensures uniform contact between the lifting rod 4 and the ball bearings during rotation, reducing friction and wear. When the motor starts, it drives the lifting rod 4 to rotate around its rotation centerline. The ball bearings, contacting the lifting rod 4 at the top of the support rod 6, support and guide the rotation of the lifting rod 4. Because the ball bearings are evenly distributed circumferentially, they can collectively bear the weight of the lifting rod 4 and the forces generated during rotation, thus ensuring smooth and accurate rotation. The use of ball bearings also reduces friction between the lifting rod 4 and the support rod 6, extending the service life of the equipment.

[0037] In embodiments of the present invention, such as Figure 2 As shown, two lifting rods 4 are installed on the platform body 3.

[0038] This lifting device achieves precise control over the lifting and rotation of the lifting rod 4 through the coordinated operation of the lifting mechanism and the reversing mechanism. This design not only improves the stability and accuracy of the lifting process, but also enhances the adaptability and flexibility of the device.

[0039] Preferably, the platform body 3 is equipped with four support legs arranged in a rectangular shape. The support legs are retractable and vertically positioned. After the platform body 3 is moved into place, the support legs extend, with their lower ends contacting the ground. These legs provide support to the platform body 3 during the lifting of the cargo container, keeping the platform body 3 stationary. This arrangement helps distribute weight, improves platform stability, and thus ensures the stability and safety of the cargo container during lifting and transfer.

[0040] The intelligent box-changing platform with the above structure is used in accordance with the following steps:

[0041] (1) A vehicle with a cargo box enters the intelligent identification zone 1. In the intelligent identification zone 1, the control system identifies the width and height dimensions of the vehicle's cargo box, such as... Figure 2 As shown;

[0042] (2) The reversing mechanism controls the lifting rod 4 to rotate, so that the lifting rod 4 switches to the working state, and at the same time the lifting mechanism controls the lifting rod 4 to move upward to the set height position;

[0043] (3) The vehicle is moved between the two platform bodies 3, and then the cargo box is unlocked from the chassis so that the cargo box can be separated from the chassis;

[0044] (4) The two platform bodies 3 move toward each other until the lifting rod 4 moves to a suitable position under the cargo box. Then the lifting mechanism on the two platform bodies 3 simultaneously controls the lifting rod 4 to move upward so that the lifting rod 4 contacts the bottom surface of the cargo box.

[0045] (5) The lifting mechanism on the two platform bodies 3 continues to control the lifting rod 4 to move upward, so that the lifting rod 4 lifts the cargo box upward and separates the cargo box from the chassis;

[0046] (6) The chassis drives away.

[0047] In step (1) above, the width of the cargo box can be obtained using image recognition. Image recognition involves capturing images of the vehicle's cargo box with a camera and then using image processing and recognition technology to obtain the cargo box's dimensions. Image recognition has advantages such as high accuracy. The height of the cargo box can be obtained using laser ranging. Laser ranging involves emitting a laser beam onto the surface of the vehicle's cargo box, receiving the reflected light signal, and calculating the distances and dimensions of various parts of the cargo box based on the ranging principle. Laser ranging has advantages such as high accuracy and fast measurement speed.

[0048] In step (4) above, after the vehicle moves between the two platform bodies 3, the control system sends a command to the walking mechanism on the platform body 3 according to the width dimension information of the cargo box. The walking mechanism on the two platform bodies 3 starts to work, so that the two platform bodies 3 move towards each other and the distance between the two platform bodies 3 decreases until the lifting rod 4 moves to a suitable support position under the cargo box. The distance between the two platform bodies 3 matches the width dimension of the cargo box, ensuring that the lifting rod 4 can contact the bottom surface of the cargo box after it rises.

[0049] In step (5) above, the lifting rod 4 supports the cargo box with at least 4 support points to ensure the cargo box is stable and safe. When a vehicle that needs to change the cargo box enters the platform, just like before unloading, the platform intelligently matches the vehicle position and moves the cargo box to the top of the vehicle frame to lower the cargo box to complete the unloading operation.

[0050] The intelligent container changing platform described above has the following advantages:

[0051] 1. It can effectively solve the constraints of cargo handling, has a convenient structure, and compared with hydraulic tailgates, the intelligent container changing platform has the advantages of low cost, high efficiency and strong operability.

[0052] 2. It enables low-cost cargo box replacement, has a reliable structure, and offers greater cost-effectiveness compared to the high cost and high risk of overhead cranes, while also improving structural safety;

[0053] 3. By setting up a cargo exchange platform, the width of the cargo box can be adjusted. When the vehicle enters the platform, the platform adapts to the outer width of the vehicle's cargo box. After the vehicle enters the warehouse, the platform adjusts and identifies the support points of the cargo box. After the cargo box installation structure is disassembled, the cargo box is lifted and the vehicle drives away from the platform for loading and use by the next vehicle or for the cargo box forklift to drive away.

[0054] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
