[0002] Four-way shuttles are intelligent warehousing and logistics equipment, and a key component of automated storage and retrieval systems (AS / RS). Compared to traditional shuttles, four-way shuttles offer greater mobility and higher space utilization. However, existing four-way shuttles are susceptible to uneven cargo weight or uneven tracks during operation, leading to instability and potential safety hazards such as tipping over or cargo falling. Furthermore, traditional four-way shuttles lack effective cushioning and protection measures when encountering sudden obstacles, easily causing equipment damage or transportation disruptions. Therefore, improvements to existing technology are necessary. Utility Model Content

[0006] Preferably, one end of the return spring is fixedly connected to the rubber seat, the other end of the return spring is fixedly connected to the rubber airbag, and the limiting ring is fixedly connected to the rubber airbag. The return spring can automatically reset the deformed rubber airbag through its elastic force.

[0007] Preferably, a reinforcing plate is fixedly connected to the lower end of the support bar, and the reinforcing plate is fixedly connected to the fixing cover, so that the reinforcing plate can support the support bar.

[0008] Preferably, two symmetrically distributed guide pins are fixedly connected to the outer side of the clamping plate. The guide pins are slidably connected to the fixing cover, and the guide pins can guide the movement of the clamping plate.

[0009] Preferably, the internally threaded tube is slidably connected to the fixed cover, and an anti-slip pad is fixedly connected to the outer side of the clamping plate, which can increase the friction between the clamping plate and the goods.

[0010] Preferably, a second bevel gear is fixedly connected to the outside of the output shaft of the motor. The second bevel gear meshes with the first bevel gear, and the second bevel gear can drive the first bevel gear to rotate.

[0021] Please see Figure 1-5 A four-way shuttle with a buffer protection structure includes a vehicle body 1, a protective mechanism 2 on the outer side of the vehicle body 1, a fixed cover 3 fixedly installed on the upper end of the vehicle body 1, a support bar 4 fixedly connected to the upper end of the fixed cover 3, an anti-slip strip 5 fixedly connected to the upper end of the support bar 4, a drive wheel 7 on the outer side of the vehicle body 1, a mounting bracket 8 fixedly connected to the top inner side of the fixed cover 3, a positive and negative screw 9 installed inside the mounting bracket 8 through bearings, two symmetrically distributed internally threaded tubes 10 connected to the outer side of the positive and negative screw 9 through threads, a clamping plate 11 fixedly connected to the outer side of the internally threaded tubes 10, a bevel gear 14 fixedly connected to the outer side of the positive and negative screw 9, and a motor 15 fixedly connected to the top inner side of the fixed cover 3.

[0022] Please see Figure 1-5 The protective mechanism 2 includes a rubber airbag 21. Multiple evenly distributed rubber airbags 21 are fixedly connected to the outer side of the vehicle body 1. Protective corners 22 are fixedly connected to the outer side of the rubber airbags 21. An exhaust port 23 is provided at the lower end of the rubber airbag 21. Multiple evenly distributed rubber seats 24 are fixedly connected to the inside of the rubber airbag 21. Each rubber seat 24 is provided with a return spring 25. A limit ring 26 is slidably connected to the outer side of the return spring 25. After the rubber airbag 21 is deformed by force, the internal gas can be discharged through the exhaust port 23. One end of the return spring 25 is fixedly connected to the rubber seat 24, and the other end of the return spring 25 is fixedly connected to the rubber airbag 21. The limit ring 26 is fixedly connected to the rubber airbag 21. The return spring 25 can automatically reset the deformed rubber airbag 21 through its elastic force.

[0023] Please see Figure 1-5A reinforcing plate 6 is fixedly connected to the lower end of the support bar 4. The reinforcing plate 6 is fixedly connected to the fixed cover 3. The reinforcing plate 6 can support the support bar 4. Two symmetrically distributed guide pins 12 are fixedly connected to the outer side of the clamping plate 11. The guide pins 12 are slidably connected to the fixed cover 3. The guide pins 12 can guide the movement of the clamping plate 11. The internal threaded tube 10 is slidably connected to the fixed cover 3. An anti-slip pad 13 is fixedly connected to the outer side of the clamping plate 11. The anti-slip pad 13 can increase the friction between the clamping plate 11 and the goods. A bevel gear 16 is fixedly connected to the outer side of the output shaft of the motor 15. The bevel gear 16 meshes with the bevel gear 14. The bevel gear 16 can drive the bevel gear 14 to rotate.

[0024] The specific implementation process of this utility model is as follows: In use, the goods are placed on the anti-slip strip 5 of the support strip 4 above the vehicle body 1 by the robotic arm, and then the motor 15 is started. The motor 15 drives the second bevel gear 16 to rotate. The second bevel gear 16 drives the positive and negative screws 9 to rotate through the first bevel gear 14. During the rotation, the positive and negative screws 9 can drive the clamping plate 11 to move through the threaded engagement with the internal threaded tube 10. The clamping plate 11 can clamp the goods through the anti-slip pad 13, so that the goods can be more stable during the movement of the vehicle body 1.

[0025] When the vehicle body 1 is impacted during movement, the object impacts the outside of the protective corner 22 and pushes the rubber airbag 21 to deform through the protective corner 22. During the deformation process, the rubber airbag 21 can expel the gas inside the rubber airbag 21 through the exhaust port 23. At the same time, the damping generated when the gas is expelled can buffer the impact force. After the rubber airbag 21 deforms, it can compress the return spring 25. When the impact force disappears, the return spring 25 returns to its original position. The return spring 25 can push the rubber airbag 21 to return to its original position through its elastic force.
