[0032] In this embodiment, a plurality of first clamping and positioning wheels 15 are equidistantly mounted on the outer wall of each U-shaped supporting rod 6 facing the middle partition rod 17 via connecting rods 16 .

[0033] In this embodiment, a plurality of second clamping and positioning wheels 18 are equidistantly installed on the outer walls on both sides of each intermediate dividing rod 17. The vertical frame 5, the U-shaped support rod 6 and the intermediate dividing rod 17 enclose a plurality of liquefied gas cylinder placement areas 7 for placing liquefied petroleum gas cylinders. Through the layout of the vertical frame, the U-shaped support rod and the intermediate dividing rod, a plurality of liquefied gas cylinder placement areas are formed. These areas are specially designed for liquefied petroleum gas cylinders to ensure that each gas cylinder can be correctly and safely positioned and fixed, thereby improving loading efficiency and safety. When the liquefied petroleum gas cylinder is placed in the liquefied gas cylinder placement area 7, one side outer wall of the liquefied petroleum gas cylinder abuts against the second clamping and positioning wheel 18, and the first clamping and positioning wheel 15 moves centripetally to clamp and abut against the other side outer wall of the liquefied petroleum gas cylinder.

[0034] In this embodiment, the first clamping and positioning wheels 15 are installed on the U-shaped support rod 6 and are connected to the support by the connecting rod 16. Their main function is to clamp one side of the liquefied gas cylinder in the centripetal direction to ensure the lateral stability of the gas cylinder during transportation and avoid rolling or collision, thereby improving the flexibility and safety of loading.

[0035] In this embodiment, the second clamping and positioning wheel 18 is installed on the outer walls of both sides of the middle dividing rod 17, and works together with the first clamping and positioning wheel 15 to fix the other side of the liquefied gas cylinder, ensuring the longitudinal stability of the cylinder in the car, preventing movement or overturning, and improving safety during transportation.

[0036] In this embodiment, a buffer base assembly 8 for buffering and shock absorption of liquefied petroleum gas cylinders is installed at the lower part of each liquefied gas cylinder placement area 7 and located on the inner bottom wall of the box body 2. Each buffer base assembly 8 includes a chassis member 9 installed at the lower part of the liquefied gas cylinder placement area 7 and located on the inner bottom wall of the box body 2, a fixing ring member 10 integrally connected to the top surface of the chassis member 9, and a buffer supporting plate 14 arranged in the fixing ring member 10 for loading liquefied gas cylinders. Support base plates 11 are symmetrically welded to the lower part of the inner wall of the fixing ring member 10, and a hydraulic buffer damper 12 is installed on the top surface of each support base plate 11 by screws. The top end of the hydraulic buffer damper 12 is connected to the bottom surface of the buffer supporting plate 14, and the top end of the hydraulic buffer damper 12 is symmetrically welded with connecting ear plates 13, which are connected to the buffer supporting plate 14 by bolts.

[0037] In this embodiment, the chassis 9, as the base part of the buffer base assembly 8, is directly installed at the bottom of the liquefied gas cylinder placement area 7 and located on the inner bottom wall of the box body 2, providing an installation platform and basic support for the entire buffer system. It ensures the stable connection of the upper components and helps to disperse the weight of the gas cylinder to prevent excessive local force. The fixed ring 10 is integrally connected to the chassis 9 on its top surface to form an annular structure surrounding the gas cylinder, and its internal space is designed to install the buffer bearing plate 14 to directly carry the gas cylinder. The existence of the fixed ring 10 strengthens the stability of the entire buffer system and provides the necessary support structure for the installation of the hydraulic buffer damper 12.

[0038] In this embodiment, not only the stable installation of the damper is ensured, but also the pressure under the weight of the gas cylinder can be evenly distributed, increasing the durability of the system. Not only the stable installation of the damper is ensured, but also the pressure under the weight of the gas cylinder can be evenly distributed, increasing the durability of the system. The hydraulic buffer damper 12 is the core shock absorbing element, the top end of which is connected to the buffer bearing plate 14 through the connecting ear plate 13, and the bottom end is fixed to the supporting base plate 11. When the vehicle is driving, it can effectively absorb and slowly release the impact energy generated by uneven road surface or sudden braking, reduce the vibration and impact of the gas cylinder, protect the gas cylinder from damage, and also reduce noise, improving the stability and safety of the transportation process.

[0039] In this embodiment, the buffer bearing plate 14 is arranged in the fixed ring 10, directly in contact with the liquefied gas cylinder, and serves as a transition carrier between the gas cylinder and the hydraulic buffer damper 12. It not only provides a flat support surface to ensure that the gas cylinder is placed firmly, but also realizes fine shock absorption protection for the gas cylinder through connection with the hydraulic buffer damper 12, further improving the safety during transportation and the protection level of the gas cylinder.

[0040] Working principle:

[0041] The double doors 3 of the liquefied petroleum gas cylinder compartment of the electric tricycle are opened, and the operator places the liquefied gas cylinders one by one into the corresponding liquefied gas cylinder placement area 7. One side of the liquefied gas cylinder naturally fits on the second clamping and positioning wheel 18, while the first clamping and positioning wheel 15 clamps the other side of the gas cylinder centripetally according to a preset position, forming a stable clamping state, ensuring the stability of the gas cylinder under any driving conditions, avoiding collision and rolling;

[0042] Under each liquefied gas cylinder, the buffer base assembly 8 starts to work. The chassis 9 provides basic support, and the buffer bearing plate 14 is installed on the top of the fixed ring 10. The hydraulic buffer damper 12 on the support base plate 11 is connected to the buffer bearing plate through the connecting ear plate 13. When the vehicle encounters bumps or sudden braking during driving, the hydraulic buffer damper can effectively absorb the impact energy and convert it into heat energy through the flow of internal liquid and slowly release it, which greatly reduces the vibration and impact transmitted to the gas cylinder, protects the gas cylinder from damage, and also improves the stability of driving;

[0043] After arriving at the destination, the double-door 3 is opened and the liquefied gas cylinders are unloaded. After unloading is completed, the carriage can be quickly adjusted back to the initial state to prepare for loading the next batch of liquefied gas cylinders of different diameters without complicated disassembly and assembly processes.

[0044] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.
