Description

Technical Field

[0001] This utility model relates to the field of electric tricycle technology, and more specifically, to a safe electric tricycle. Background Technology

[0002] Electric tricycles have become an important means of transportation for people's livelihood in urban and rural areas of China, especially in rural areas, urban-rural fringe areas and short-distance logistics, due to their advantages such as being economical and practical, easy to operate and convenient for carrying goods and people.

[0003] Traditional tricycles lack dedicated ramps, requiring manual handling to lift heavy objects from the ground into the cargo bed. This is laborious and carries the risk of slipping and causing injury. Temporary ramps need to be reliably stored and secured to the frame when not in use to prevent accidental slippage and ejection during driving, which could create safety hazards. Fixed-height railings cannot accommodate goods of different sizes or stacking heights. If the railings are too low, the goods are prone to falling off during bumps, while if they are too high, they may hinder loading and unloading operations. Utility Model Content

[0029] Please see Figures 1-5A safe electric tricycle includes a tricycle body 1, which includes a frame 2 and a cargo box 3. The frame 2 has a support plate 4, and sliding rods 5 are provided on both sides of the support plate 4. Limiting plates 6 are provided on the sliding rods 5. The frame 2 has sliding grooves 7 that cooperate with the sliding rods 5, and a limiting groove 8 is provided at one end of the sliding grooves 7. The cargo box 3 has multiple support sleeves 9, and support rods 10 are slidably mounted on the support sleeves 9. Railings 11 connect the support rods 10, and one of the support rods 10 has an adjustment device. The adjustment device includes an adjustment groove 12, with symmetrical adjustment blocks 13 arranged in the adjustment groove 12. An adjustment rod 14 is provided on the adjustment block 13. An adjustment hole 15 that cooperates with the adjustment rod 14 is provided on the support sleeve 9. Overlapping rods 16 are provided on both sides of the support plate 4. Overlapping frames 17 that cooperate with the overlapping rods 16 are provided on both sides of the frame 2. Overlapping bolts 18 are provided on the overlapping frames 17. The overlapping bolts 18 are rotatably mounted on the overlapping frames 17. A limiting ring 19 is provided on one side of the overlapping bolts 18. Anti-slip textures 20 are provided on the support plate 4.

[0030] In this embodiment, when using the tricycle body 1 to haul goods, the goods need to be loaded onto the tricycle body 1. The overlapping bolt 18 is rotated to open the overlapping frame 17. The limiting ring 19 prevents the overlapping bolt 18 from falling off. Then, the support plate 4 is lifted upwards. After the overlapping rod 16 of the support plate 4 leaves the overlapping frame 17, the support plate 4 is pulled. The sliding rod 5 of the support plate 4 slides within the sliding groove 7. When it moves to one end of the sliding groove 7, the sliding rod 5 engages with the limiting groove 8, causing the support plate 4 to rotate so that one end overlaps the ground, forming... The ramp allows the tricycle body 1 to be loaded and unloaded via the support plate 4 for cargo transport. The anti-slip texture 20 improves the anti-slip performance of the support plate 4. After cargo transport is completed, the support plate 4 is lifted upwards, causing the sliding rod 5 to leave the limiting groove 8 and move onto the sliding groove 7. Then, the support plate 4 is retracted onto the frame 2, and the overlapping rod 16 is placed on the overlapping frame 17 and fixed with the overlapping bolts 18 to prevent the overlapping rod 16 from leaving the overlapping frame 17 and causing the support plate 4 to slip, thereby improving the safety of cargo transport and driving.

[0031] Please see Figures 4-5 As one embodiment of the adjustment device: an adjustment plate 21 is slidably provided in the adjustment groove 12, and adjustment slide rods 22 are provided on both sides of the adjustment plate 21. An inclined groove 23 that cooperates with the adjustment slide rod 22 is provided on the adjustment block 13. A moving rod 24 is slidably provided on the support rod 10. The bottom of the moving rod 24 is fixedly connected to the adjustment plate 21, and a moving head 25 is fixedly provided on the top. A moving groove 26 is provided on the support rod 10. A moving plate 27 is provided in the moving groove 26 of the moving rod 24. A moving spring 28 is provided between the moving plate 27 and the moving groove 26.

[0032] More specifically, based on the height of the goods, the height of the railing 11 is adjusted, and the moving head 25 is pulled upward. The moving head 25 drives the moving rod 24 to move, and the moving rod 24 drives the moving plate 27 to move within the moving groove 26 and compress the moving spring 28. The moving rod 24 drives the adjusting plate 21 to move upward. Through the cooperation of the adjusting slide rod 22 and the inclined groove 23, the adjusting block 13 and the adjusting rod 14 are moved into the adjusting groove 12, so that the adjusting rod 14 leaves the adjusting hole 15, thereby driving the railing 11 and the support rod 10 to adjust their height in the vertical direction. The height of the railing 11 is adjusted by holding the railing 11 and releasing the moving head 25. The moving plate 27 moves downward and resets under the elastic force of the moving spring 28, and drives the moving rod 24 to move downward. The adjusting plate 21 drives the adjusting slide rod 22 to move downward and cooperate with the tilting groove 23, so that the adjusting block 13 and the adjusting rod 14 move to both sides and are inserted into the adjusting hole 15 through the adjusting rod 14 to fix the relative position of the support rod 10 and the support sleeve 9, thereby adjusting the height of the railing 11 and improving the safety of transporting goods and driving.

[0033] In summary, when using or operating the overall equipment: When using the tricycle body 1 to haul goods, the goods need to be moved onto the tricycle body 1. Rotate the overlapping bolt 18 to open the overlapping frame 17. The limiting ring 19 prevents the overlapping bolt 18 from falling off. Then, lift the support plate 4 upwards. After the overlapping rod 16 of the support plate 4 leaves the overlapping frame 17, pull the support plate 4. The sliding rod 5 of the support plate 4 slides within the sliding groove 7. When it moves to one end of the sliding groove 7, the sliding rod 5 engages with the limiting groove 8. Rotate the support plate 4 so that one end overlaps with... On the ground, a ramp is formed, allowing the tricycle body 1 to be loaded and unloaded via the support plate 4 for transporting goods. The anti-slip texture 20 is provided to improve the anti-slip performance of the support plate 4. After the goods are transported, the support plate 4 is lifted upwards, causing the sliding rod 5 to leave the limiting groove 8 and move onto the sliding groove 7. Then, the support plate 4 is retrieved onto the frame 2, and the overlapping rod 16 is placed on the overlapping frame 17 and fixed with the overlapping bolts 18 to prevent the overlapping rod 16 from leaving the overlapping frame 17 and causing the support plate 4 to slip, thereby improving the safety of transporting goods and driving.

[0034] Adjust the height of the railing 11 according to the height of the goods, and pull the moving head 25 upward. The moving head 25 drives the moving rod 24 to move. The moving rod 24 drives the moving plate 27 to move within the moving groove 26 and compress the moving spring 28. The moving rod 24 drives the adjusting plate 21 to move upward. By adjusting the cooperation of the sliding rod 22 and the inclined groove 23, the adjusting block 13 and the adjusting rod 14 are moved into the adjusting groove 12, so that the adjusting rod 14 leaves the adjusting hole 15, thereby driving the railing 11 and the support rod 10 to adjust their height in the vertical direction. Then, adjust the height of the railing 11. After adjustment, hold the railing 11 and release the moving head 25. The moving plate 27 moves downward and resets under the elastic force of the moving spring 28, and drives the moving rod 24 to move downward. The adjusting plate 21 drives the adjusting slide rod 22 to move downward and cooperate with the tilting groove 23, so that the adjusting block 13 and the adjusting rod 14 move to both sides and are inserted into the adjusting hole 15 through the adjusting rod 14 to fix the relative position of the support rod 10 and the support sleeve 9, thereby adjusting the height of the railing 11 and improving the safety of transporting goods and driving.
