Four sliding grooves 17 are evenly distributed at each corner of the outer casing 2. Eight pin holes 5 are evenly distributed in pairs in the middle of the four sliding grooves 17, and all pin holes 5 are located on the surface of the outer casing 2. Four extension frames 3... All four extension frames 3 are installed in the grooves 17 on the surface of the outer shell 2, and four fixing pins 4 are evenly inserted through the four extension frames 3 and installed in the corresponding pin holes 5 on the top surface of the outer shell 2. The outer shell 2 is installed on the top of the frame 1 by screws, and the four grooves 17 are evenly arranged at each corner of the outer shell 2. The eight pin holes 5 are evenly arranged in pairs in the middle of the four grooves 17, and the pin holes 5 are all located on the surface of the outer shell 2. The four extension frames 3 are all installed in the grooves 17 on the surface of the outer shell 2, and the four fixing pins 4 are evenly inserted through the four extension frames 3 and installed in the corresponding pin holes 5 on the top surface of the outer shell 2. The four first drive wheels 18, second drive wheels 19 and pulleys 16 are evenly installed in pairs on the frame. The two sides of the frame 1 are connected by chains, and the rotation shafts of the four first power wheels 18 and the four second power wheels 19 are all inserted into the interior of the frame 1. The two ends of the coupling 10 are connected to one of the chains of each group of second power wheels 19, and the two ends of the reversing shaft 15 are connected to one of the chains of each group of first power wheels 18. The first servo motor 7 is shaft-connected to the lifter 13 on the side near the battery 6, and the two ends of the power shaft 14 are shaft-connected to the two lifters 13. The eight lifting cams 12 are evenly arranged on both sides of the two lifting plates 11 in groups of two. The two ends of the two lifters 13 are shaft-connected to the two lifting cams 12 of each group.

[0025] The second servo motor 9 is located in the middle of the frame 1. A battery 6 is installed to the left of the second servo motor 9, providing power to the entire four-way vehicle. A controller 8 is installed to one side of the second servo motor 9 to receive external control signals and control the four-way vehicle to perform corresponding operations. A first servo motor 7 is installed behind the battery 6. The first servo motor 7 and the second servo motor 9 drive the entire four-way vehicle. Lifting plates 11 are installed to the left of the battery 6 and to the right of the controller 8, respectively. Lifters 13 are provided between the lifting plates 11 and the battery 6, and between the lifting plates 11 and the controller 8. Second drive wheels 19 are located at both ends of the two lifting plates 11. The raising or lowering of the lifting plates 11 drives the second drive wheels 19 to rise or fall. When descending, it will touch the ground. When the second power wheel 19 continues to descend, it will lift the entire frame 1 of the four-way vehicle. When the second power wheel 19 descends, the entire frame 1 of the four-way vehicle will descend, thereby controlling the lifting and lowering of the four-way vehicle. The lifting and lowering of the lifting plate 11 is carried out by the lifting cam 12. There are two sets of lifting cams 12 at both ends of the two lifting plates 11. The two lifting cams 12 of each set of lifting cams 12 are mirrored with the lifting plate 11 as the center. The two sets of lifting cams 12 of the two lifting plates 11 are axially connected to the lifter 13. The two lifters 13 are axially connected by the power shaft 14. The lifter 13 near the battery 6 is axially connected to the first servo motor 7. It should be noted that a reducer is provided at the connection between the first servo motor 7 and the second servo motor 9 and the lifter 13, the coupling 10 and the reversing shaft 15.

[0026] When the four-way vehicle is in use, the PLC of the vehicle control system issues a Y-direction command. When the controller 8 inside the frame 1 receives the signal to move in the X-axis direction, according to the control signal, the controller 8 controls the second servo motor 9 to rotate. After being adjusted by the reducer, the second servo motor 9 drives the coupling 10 to rotate via a chain. The rotation of the coupling 10 will drive the two sets of second drive wheels 19 at both ends of the coupling 10 to rotate. Each set of second drive wheels 19 is linked by a chain. When the coupling 10 drives one of the two sets of second drive wheels 19, the entire set of second drive wheels 19 will rotate. Since the direction corresponding to the second drive wheel 19 is the X-axis, when the two sets of second drive wheels 19 rotate, the vehicle moves in the X-axis direction.

[0027] When the four-way vehicle needs to move towards the Y-axis, the controller 8 inside the frame 1 receives a signal to move towards the Y-axis. According to the control signal, the controller 8 controls the second servo motor 9 to rotate, so that the second servo motor 9 drives the reversing shaft 15 to rotate via a chain. The rotation of the reversing shaft 15 will drive the two sets of first power wheels 18 at both ends of the reversing shaft 15 to rotate. Each set of first power wheels 18 is linked by a chain. When the reversing shaft 15 drives one of the two sets of first power wheels 18, the entire set of first power wheels 18 will rotate. Since the direction corresponding to the first power wheel 18 is the Y-axis, when the two sets of first power wheels 18 rotate, the vehicle moves towards the Y-axis. When the first power wheel 18 rotates, the pulley 16 on one side of the first power wheel 18 will balance the movement of the entire four-way vehicle to prevent only the right end of the four-way vehicle from moving when moving towards the Y-axis.

[0028] When the PLC of the vehicle control system issues a reversing or lifting command, the controller 8 controls the first servo motor 7 to rotate, which in turn drives the gear transmission of the left lifter 13 through a reducer. The left lifter 13 drives the gear of the right lifter 13 to rotate through the power shaft 14 of the intermediate gear. The gear drives the rotation of the two sets of lifting cams 12 through the intermediate shaft, thereby realizing the vertical up, middle and down movement of the lifting plate 11.

[0029] Four grooves 17 are provided on the surface of the outer casing 2, and an extension frame 3 is installed inside each groove 17. Four fixing pins 4 are provided on the top of each of the four extension frames 3, and two pin holes 5 are located in the middle of each groove 17. The two pin holes 5 in each groove 17 are located at both ends of the groove 17. The four extension frames 3 are installed into the pin holes 5 in the middle of the groove 17 through the four fixing pins 4, thus fixing the extension frames 3 inside the groove 17. When it is necessary to increase the loading area of ​​the four-way vehicle, the four fixing pins 4 can be removed from the pin holes 5 in the middle of the slide 17 and the extension frame 3, and the four extension frames 3 can be moved so that the pin holes 5 of the extension frame 3 are aligned with the other pin holes 5 of the four slide 17. The fixing pins 4 are then inserted into the pin holes 5 in the middle of the slide 17 through the pin holes 5 of the extension frame 3 to complete the fixing of the extension frame 3. The extended extension frame 3 increases the accessible mold of the four-way vehicle. Specific Implementation Example 2:

[0031] Reference Figure 1-5A four-way vehicle with optimized interior space is further based on the basic structure in Specific Embodiment 1. Four guide wheels can be provided on both sides of the left and right ends of the two lifting plates 11. The four guide wheels are vertically connected to the surface of the inner wall of the frame 1. When the two lifters 13 drive the two sets of lifting cams 12 to rotate, the four sets of lifting cams 12 will drive the two lifting plates 11 to rise. The guide wheel sets at both ends of the two lifting plates 11 will provide directional guidance during the rise of the lifting plates 11 to prevent the lifting plates 11 from deviating from the movement trajectory during the rise.

[0032] In summary:

[0033] 1. The outer casing 2 has four sliding grooves 17 on its surface, and an extension frame 3 is installed inside each of the sliding grooves 17. Each of the four extension frames 3 has four fixing pins 4 at its top, and two pin holes 5 are located in the middle of each of the four sliding grooves 17. The two pin holes 5 in each sliding groove 17 are located at both ends of the sliding groove 17. The four extension frames 3 are installed into the pin holes 5 in the middle of the sliding grooves 17 through the four fixing pins 4, thus fixing the extension frames 3 inside the sliding grooves 17. This design allows for the addition of a four-way vehicle carrying capacity. When the area of ​​the goods is determined, the four fixing pins 4 can be removed from the pin holes 5 in the middle of the slide 17 and the extension frame 3, and the four extension frames 3 can be moved so that the pin holes 5 of the extension frame 3 are aligned with the other pin holes 5 of the four slide 17. The fixing pins 4 are then inserted into the pin holes 5 in the middle of the slide 17 through the pin holes 5 of the extension frame 3, thus completing the fixing of the extension frame 3. The extended extension frame 3 increases the contact area of ​​the four-way vehicle, solving the problem of not being able to increase the contact area according to the width of different goods.

[0034] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them.
