[0002] Electric tricycles are a convenient mode of transportation powered by electricity. Among them, models with canopies are particularly popular due to their unique design. These tricycles are equipped with fully or semi-enclosed canopy structures that can effectively protect against wind, rain, and sun, providing drivers with all-weather travel protection. The canopy not only enhances the overall safety of the vehicle but also improves passenger comfort. The interior usually has ample storage space, combining practicality and convenience.

[0003] However, the covers of existing electric tricycles typically use hydraulic rods to flip and open, which is inconvenient when closing. The user must completely flip the cover and apply pressure to close it, requiring considerable physical effort, especially for the elderly or those with weaker physical strength. Therefore, there is an urgent need for an electric tricycle with a convenient cover for opening and closing. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this application provides an electric tricycle that uses a buffer mechanism to assist in the flipping and closing of the cover, reducing the force applied by the user to flip the cover and avoiding the trouble of the user having to exert effort to flip and close the cover, making it convenient for the elderly or users with weak physical strength to use, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An electric tricycle includes: a frame and a cover that rotates at the front end of its base plate. Both sides of the inner cavity wall of the cover and the base plate of the frame are provided with buffer mechanisms to assist in opening and closing the cover. The buffer mechanisms include a gas spring, an annular adjusting plate, and a tension spring. The gas spring and its output piston rod are rotatably mounted on the inner cavity wall of the cover and the end face of the base plate of the frame to support the cover. The annular adjusting plate is sleeved outside the gas spring to adjust the tension length and rebound force of the tension spring. The tension spring, wrapped around the outside of the gas spring, rebounds after being stretched to assist in flipping and closing the cover.

[0007] Preferably, the inner walls on both sides of the housing are provided with connecting shafts, the piston rod is provided with a top end plate at the end away from the gas spring, and the other end of the top end plate is provided with a first lug, which is rotatably mounted on the outer wall of the connecting shaft.

[0008] Preferably, the end face of the frame base plate is provided with two symmetrically distributed vertical plates, and a rotating shaft is provided between the two vertical plates. The end of the gas spring away from the piston rod is provided with a bottom end plate, and the other end of the bottom end plate is provided with a second lug. The second lug is rotatably mounted on the outer wall of the rotating shaft.

[0009] Preferably, the end face of the annular adjusting plate is provided with an opening, and the annular adjusting plate is sleeved on the outside of the gas spring through the opening and located between the top end plate and the bottom end plate, and the two ends of the tension spring are respectively installed on the end faces of the annular adjusting plate and the bottom end plate.

[0010] Preferably, the end face of the top end plate is evenly provided with a plurality of threaded rods, and the end face of the annular adjusting plate is provided with a sliding hole at the position corresponding to the threaded rod, and the annular adjusting plate slides on the outer wall of the threaded rod through the sliding hole.

[0011] Preferably, two limiting nuts are provided at the end of the outer wall of the threaded rod located below the annular adjusting plate. The two limiting nuts are threaded onto the outer wall of the threaded rod and are in close contact with the lower end face of the annular adjusting plate in sequence, and the internal threads of the two limiting nuts are in opposite directions.

[0012] Preferably, the length of the gas spring in its contracted state is equal to the sum of the lengths of the threaded rod and the tension spring in their free state.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] By setting up a buffer mechanism, a gas spring is used to push the cover to flip open on the chassis base plate. At the same time, the piston rod on the gas spring pushes the top end plate and the annular adjustment plate to move, causing the tension spring to deform. When the cover is flipped to close, the tension spring assists in flipping and closing the cover, reducing the force required by the user to flip the cover and avoiding the inconvenience of having to exert effort to flip and close the cover. This realizes the opening and closing of the cover of the electric tricycle. Moreover, by adjusting the distance between the annular adjustment plate and the bottom end plate, the extension length and rebound force of the tension spring are changed, and the tension force of the buffer mechanism assisting in flipping and closing the cover is adjusted, making it convenient for elderly people or users with weak physical strength to use.

[0022] Combination Figures 1-5 As shown in this embodiment, an electric tricycle includes: a frame 1 and a cover 2 that rotates at the front end of its base plate; flipping the cover 2 opens and closes the frame 1, thereby enhancing the overall safety and comfort of the vehicle. At the same time, the cover 2 provides wind and rain protection and sun protection for the user, providing all-weather travel protection for the driver.

[0023] In this embodiment, buffer mechanisms 3 for assisting the opening and closing of the cover 2 are provided between the inner walls of both sides of the cover 2 and the bottom plate of the frame 1. The buffer mechanism 3 includes a gas spring 31, an annular adjusting plate 34 and a tension spring 36. The gas spring 31 and its output piston rod are rotatably installed on the inner wall of the cover 2 and the end face of the bottom plate of the frame 1 to support the cover 2. The gas spring 31 is used to push the cover 2 to flip open on the bottom plate of the frame 1, thereby opening the cover 2.

[0024] In this embodiment, the annular adjustment plate 34 is sleeved on the outside of the gas spring 31 to adjust the tension length and rebound force of the tension spring 36. The tension spring 36 surrounds the outside of the gas spring 31 and rebounds after being stretched to assist the cover 2 in flipping and closing. The piston rod on the gas spring 31 pushes the top end plate 32 and the annular adjustment plate 34 to move, causing the tension spring 36 to deform. When the cover 2 is closed, the tension of the tension spring 36 can assist the cover 2 in flipping and closing, reducing the force required by the user to flip the cover 2 and avoiding the trouble of the user having to exert effort to flip and close the cover 2.

[0025] In this embodiment, both sides of the inner cavity wall of the cover 2 are provided with connecting shafts 21. The piston rod is provided with a top end plate 32 at the end away from the gas spring 31, and the other end of the top end plate 32 is provided with a first lug 321. The first lug 321 is rotatably mounted on the outer wall of the connecting shaft 21. The piston rod is rotatably mounted on the connecting shaft 21 through the first lug 321 to prevent interference between the cover 2 and the gas spring 31 and the piston rod when the cover 2 is flipped, thus ensuring the flipping operation of the cover 2.

[0026] In this embodiment, the end face of the frame 1 base plate is provided with two symmetrically distributed upright plates 11, and a rotating shaft 12 is provided between the two upright plates 11. The end of the gas spring 31 away from the piston rod is provided with a bottom end plate 33, and the other end of the bottom end plate 33 is provided with a second lug 331. The second lug 331 is rotatably mounted on the outer wall of the rotating shaft 12. The second lug 331 is used to rotatably mount the gas spring 31 on the rotating shaft 12 to prevent the gas spring 31 and piston rod from interfering with the frame 1 base plate as the cover 2 flips, thus ensuring the use of the gas spring 31.

[0027] In this embodiment, the end face of the annular adjusting plate 34 is provided with a through-hole 341. The annular adjusting plate 34 is sleeved on the outside of the gas spring 31 through the through-hole 341 and located between the top end plate 32 and the bottom end plate 33. The two ends of the tension spring 36 are respectively installed on the end faces of the annular adjusting plate 34 and the bottom end plate 33. The annular adjusting plate 34 slides outside the gas spring 31 and the piston rod through the through-hole 341 to adjust the position of the annular adjusting plate 34, prevent the annular adjusting plate 34 from interfering with the gas spring 31 and the piston rod, and realize the adjustment of the tension length and rebound force of the tension spring 36.

[0028] In this embodiment, a plurality of threaded rods 35 are evenly arranged on the end face of the top end plate 32. A sliding hole 342 is provided on the end face of the annular adjustment plate 34 at the position corresponding to the threaded rod 35. The annular adjustment plate 34 slides on the outer wall of the threaded rod 35 through the sliding hole 342. By sliding the position of the annular adjustment plate 34 on the outer wall of the threaded rod 35 through the sliding hole 342, the distance between the annular adjustment plate 34 and the bottom end plate 33 is adjusted, thereby changing the tension length of the tension spring 36 and the tension of the auxiliary cover 2 for flipping and closing, making it convenient for elderly people or users with weak physical strength to use.

[0029] In this embodiment, two limiting nuts 351 are provided at one end of the outer wall of the threaded rod 35 located below the annular adjusting plate 34. The two limiting nuts 351 are threaded onto the outer wall of the threaded rod 35 and are sequentially pressed against the lower end face of the annular adjusting plate 34, and the internal thread directions of the two limiting nuts 351 are opposite. The two limiting nuts 351 with opposite internal thread directions are sequentially tightened on the threaded rod 35, so that the two limiting nuts 351 are sequentially pressed against the lower end face of the annular adjusting plate 34, limiting the position of the annular adjusting plate 34 after adjustment, and ensuring the stability of the annular adjusting plate 34 after adjustment.

[0030] The working principle of this utility model is as follows: The electric tricycle proposed in this application uses a buffer mechanism 3 between the cover 2 and the bottom plate of the frame 1. The piston rod at the output end of the gas spring 31 pushes the cover 2 to flip open on the bottom plate of the frame 1, thus opening the cover 2. At the same time, the piston rod pushes the top end plate 32 and the annular adjusting plate 34 to move, causing the tension spring 36 to deform. When the cover 2 is flipped to close, the tension spring 36 assists in flipping and closing the cover 2, reducing the force required by the user to flip the cover 2 and avoiding the trouble of the user having to exert effort to flip and close the cover 2. Moreover, by adjusting the distance between the annular adjusting plate 34 and the bottom end plate 33, the extension length of the tension spring 36 and the tension force assisting in flipping and closing the cover 2 are changed, making it convenient for the elderly or users with weak physical strength to use.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
