Currently, the drive wheels and driven wheels of the four-way vehicle are fixedly connected to the vehicle body. When traveling on a deformed track, the drive wheels and driven wheels cannot exert force evenly, which can lead to vehicle stalling, vehicle vibration, and abnormal noise. Utility Model Content

[0004] The purpose of this utility model is to provide a four-way vehicle reversing floating structure to solve the technical problems existing in the background art.

[0005] This utility model provides a four-way vehicle reversing floating structure, including a reversing mechanism, a Y-wheel bridge plate one and a Y-wheel bridge plate two located at both ends of the reversing mechanism, and an X-wheel bridge plate arranged on the same side as the Y-wheel bridge plate. Four Y-direction traveling wheels are evenly distributed at both ends of the Y-wheel bridge plate one and the Y-wheel bridge plate two, two X-direction traveling wheels are mounted on the vehicle frame, and the other two X-direction traveling wheels are mounted at both ends of the X-wheel bridge plate.

[0006] The reversing mechanism drives the Y-wheel bridge plate one and the Y-wheel bridge plate two to rise and fall synchronously, and both the Y-wheel bridge plate one and the Y-wheel bridge plate two are movably connected to the reversing mechanism. The X-wheel bridge plate is connected to the reversing mechanism through a bearing.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0021] like Figure 1-4 As shown, the present invention provides a four-way vehicle reversing floating structure, including a reversing mechanism 2, a Y-wheel bridge plate 3 and a Y-wheel bridge plate 4 located at both ends of the reversing mechanism 2, and an X-wheel bridge plate 5 arranged on the same side as the Y-wheel bridge plate 3. Four Y-direction traveling wheels 7 are evenly distributed at both ends of the Y-wheel bridge plate 3 and the Y-wheel bridge plate 4. Two X-direction traveling wheels 6 are mounted on the frame 1, and the other two X-direction traveling wheels 6 are mounted at both ends of the X-wheel bridge plate 5.

[0022] The four-way vehicle can travel in either the X or Y direction, enabling flexible multi-directional transport of goods by switching directions. The vehicle is powered in both the X and Y directions by a drive motor 16 and a three-way reducer 17. When traveling in the X direction, the drive sprocket 19 rotates, cooperating with corresponding transmission components to achieve X-direction movement. When traveling in the Y direction, the universal couplings 18 on both sides rotate, cooperating with corresponding transmission components to achieve Y-direction movement. The reversing mechanism 2 can drive the Y-wheel bridge plate 3 and the Y-wheel bridge plate 4 to rise and fall synchronously, thereby raising and lowering the Y-direction traveling wheels 7 to achieve reversal.

[0023] Both Y-wheel bridge plate 3 and Y-wheel bridge plate 4 are movably connected to the reversing mechanism 2, and the X-wheel bridge plate 5 is connected to the reversing mechanism 2 via bearings; the Y-wheel bridge plate 3 and X-wheel bridge plate 5 are slidably connected, and the Y-wheel bridge plate 4 is slidably connected to the frame 1. The reversing mechanism 2 includes a drive component 201, a shaft structure driven by the drive component 201, and cam structures 205 fixed on both sides of the shaft structure. Rollers 206 are bolted to the cam structures 205. Slots 8 for the rollers 206 are correspondingly provided on the Y-wheel bridge plate 3 and Y-wheel bridge plate 4. The shaft structure is connected to the frame 1 via bearings.

[0024] In the above scheme, the shaft structure includes a long shaft structure 202 and a short shaft structure 203, which are connected by a perforated coupling 204. This combined shaft structure facilitates the installation and disassembly of each component, while also possessing a certain deformation capacity, resulting in higher stability and safety. The drive component 201 uses a motor as its power source, transmitting power to the shaft structure via gears, causing the shaft structure to rotate. As the shaft structure rotates, the cam structure 205 at its end rotates synchronously, causing the roller 206 to roll within the slide groove 8, thus synchronously raising and lowering the Y-wheel bridge plate 3 and the Y-wheel bridge plate 4. The slide groove 8 is L-shaped to ensure smooth raising and lowering of the Y-wheel bridge plate 3 and the Y-wheel bridge plate 4.

[0025] Linear guide rail 9 is provided on the X-axle wheel plate, and linear guide rail 10 is provided on the frame 1. The Y-wheel wheel plate 3 and Y-wheel wheel plate 4 are slidably connected to linear guide rail 9 and linear guide rail 10 respectively via slider 11 and slider 12. When Y-wheel wheel plate 3 and Y-wheel wheel plate 4 rise and fall synchronously, they are limited by linear guide rail 9 and linear guide rail 10 to ensure that Y-wheel wheel plate 3 and Y-wheel wheel plate 4 move vertically. When the proximity switch on the frame 1 detects that the lifting height has reached the set value, the drive motor 16 starts to operate, driving the four-way vehicle to travel along the Y direction through the three-way reducer 17 and the universal coupling 18.

[0026] The X-wheel bridge plate 5 is provided with fixed supports 13 at both ends. The X-direction traveling wheel 6 is fixed to the fixed supports by bolts. The frame 1 has through slots 14 for the fixed supports 13 to pass through. The height of the fixed supports 13 is less than the height of the through slots 14. Nylon plates 15 are provided in the through slots 14 and are located on both sides of the fixed supports 13.

[0027] In the above scheme, the X-wheel axle plate 5 is connected to the long shaft structure 202 via bearings. When traveling in the X direction, the X-wheel axle plate 5 can rotate around the long shaft structure 202, thereby causing the X-direction traveling wheels 6 on both sides of the X-wheel axle plate 5 to float. During the floating process, the nylon plate 15 provides X-direction restraint. When traveling in the Y direction, the Y-wheel axle plate can rotate around the roller 206, thereby causing the X-direction traveling wheels 6 on both sides of the Y-wheel axle plate 3 to float.

[0028] The Y-wheel bridge plate 3 and X-wheel bridge plate 5 form a floating module, ensuring that one end of the four-way vehicle's wheel remains floating while traveling in the X or Y direction. This maintains smooth operation even when the four-way vehicle's track deforms, reducing vehicle vibration and abnormal noise during travel. Over long periods of operation, this extends the lifespan of both the shelving and the four-way vehicle, reducing warehouse and vehicle maintenance and thus lowering the cost of using four-way vehicles for high-density warehousing.

[0029] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
