Description

Technical Field

[0001] This utility model relates to the field of electric tricycles, and more particularly to an electric reverse tricycle bicycle. Background Technology

[0002] Traditional electric reversing tricycles typically employ a two-wheel front and single-wheel rear layout, with the center of gravity concentrated at the front. This structure demands high stability during steering. However, existing steering systems often use rigid connection designs, such as direct-drive steering rods or fixed-angle mechanisms, preventing the wheels from dynamically adapting to road surface changes during steering. Due to the lack of effective cushioning, when the vehicle encounters bumps or lateral impacts, the rigid steering mechanism directly transmits the impact force to the vehicle body, easily causing momentary front wheel vibration or oversteer, thus affecting the overall handling stability of the vehicle. For example, when one front wheel is impacted by the road surface, a rigid connection may cause a sudden change in wheel deflection angle, leading to unexpected body roll or fishtailing, and in severe cases, even loss of vehicle control. Utility Model Content

[0003] The main purpose of this utility model is to provide an electric tricycle that solves the technical problems of electric tricycles having no steering cushioning, being prone to shaking or oversteering.

[0004] To achieve the above objectives, this utility model provides an electric reversible tricycle, comprising: a cargo carrier body with torsion members rotatably connected to both sides, the torsion members being used to mount the front wheel; a steering assembly including a pair of transmission rods, a steering tube, and a linkage member, the steering tube being rotatably disposed on one side of the cargo carrier body, the linkage member being fixedly disposed at one end of the steering tube, one end of the transmission rod being movably connected to the linkage member, and the other end of the transmission rod being movably connected to the torsion member; and a buffer assembly disposed at the bottom end of the cargo carrier body, the buffer assembly having retractable ends that are movably connected to the torsion members respectively.

[0005] Optionally, the buffer assembly includes an intermediate component and a pair of telescopic rods. The intermediate component is fixedly disposed at the bottom end of the cargo vehicle body, and the two telescopic rods are respectively hinged to both ends of the intermediate component. The end of the telescopic rod opposite to the intermediate component is hinged to the torsion member.

[0006] Optionally, the transmission rod is provided with connecting seats at both ends for movable connection. The connecting seats are connected to the transmission rod by thread, and the connecting seats are provided with movable bearings.

[0007] Optionally, the cargo vehicle body is provided with fixed seats on both sides, and a first reinforcing rib is connected between the fixed seats and the bottom end of the cargo vehicle body. The torsion member is provided with a rotating shaft, and the torsion member is rotatably connected to the fixed seat with the rotating shaft as the axis.

[0008] Optionally, a second reinforcing rib is connected between the intermediate component and the bottom surface of the cargo vehicle body, and the second reinforcing rib is configured to be parallel to the telescopic rod.

[0009] Optionally, it also includes an upper tube and a rear upper fork tube. The upper tube is U-shaped and connected to the rear upper fork tube. A traction tube is provided around the periphery of the cargo vehicle body, and both ends of the upper tube are connected to the traction tube.

[0010] Optionally, the cargo vehicle body includes a chassis and a cargo box, the cargo box is disposed on the chassis, the cargo box is provided with a flange, at least two support seats are provided on the outer side of the chassis, and support tubes are provided on the support seats, the support tubes pressing the traction tube against the flange.

[0013] Optionally, the carriage is equipped with a storage board.

[0014] The technical solution provided by this utility model utilizes the linkage and transmission rod structure in the steering assembly to ensure synchronized movement of the two front wheels during steering. This avoids sudden changes in steering angle caused by rigid connections, thereby reducing the risk of body roll or fishtailing and improving handling stability during high-speed steering and emergency obstacle avoidance. The retractable design of the buffer assembly absorbs road bumps and lateral impacts, reducing the impact of rigid transmission on the vehicle body. This allows the wheels to maintain stable contact when encountering uneven road surfaces, reducing the risk of vibration and loss of control.

[0023] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0024] This utility model provides an electric reversible tricycle, comprising: a cargo carrier body 1, with torsion members 13 rotatably connected to both sides, the torsion members 13 being used to mount the front wheel; a steering assembly 2, comprising a pair of transmission rods 21, a steering tube 22, and a linkage member 23, the steering tube 22 being rotatably disposed on one side of the cargo carrier body 1, the linkage member 23 being fixedly disposed at one end of the steering tube 22, one end of the transmission rods 21 being movably connected to the linkage member 23, and the other end of the transmission rods 21 being movably connected to the torsion member 13; and a buffer assembly 3 disposed at the bottom end of the cargo carrier body 1, the buffer assembly 3 having retractable ends that are movably connected to the torsion members 13 respectively.

[0025] In the technical solution provided by this utility model, the linkage 23 and transmission rod 21 in the steering assembly 2 enable the front wheels on both sides to maintain synchronous movement during steering, avoiding sudden changes in steering angle caused by rigid connection, thereby reducing the risk of body roll or fishtailing and improving handling stability during high-speed steering and emergency obstacle avoidance. The retractable design of the buffer assembly 3 can absorb road bumps and lateral impacts, reducing the impact of rigid transmission on the vehicle body, allowing the wheels to maintain stable contact when encountering uneven road surfaces, reducing the risk of vibration and loss of control, ensuring that the vehicle body can maintain balance under complex road conditions, and improving overall safety and driving experience.

[0026] The buffer assembly 3 includes a middle component 31 and a pair of telescopic rods 32. The middle component 31 is fixedly mounted on the bottom end of the cargo vehicle body 1. The two telescopic rods 32 are respectively hinged to both ends of the middle component 31, and the end of the telescopic rod 32 facing away from the middle component 31 is hinged to the torsion member 13. Through the hinged structure of the middle component 31 and the two telescopic rods 32, the buffer assembly 3 can independently absorb the impact force of the wheels on both sides, avoid the impact of unilateral bumps on the other side wheel, and improve driving smoothness and steering stability.

[0027] The transmission rod 21 has connecting seats 211 at both ends for movable connection. The connecting seats 211 are connected to the transmission rod 21 by thread, and the connecting seats 211 contain movable bearings. The thread connection facilitates the adjustment of the length of the transmission rod 21. The movable bearings include multi-degree-of-freedom bearings such as fisheye bearings 212 and eye bearings, allowing the transmission rod 21 to swing flexibly within a certain angle, reducing mechanical interference during steering, and improving steering flexibility and durability.

[0028] The cargo vehicle body 1 has fixed seats 121 on both sides. A first reinforcing rib 1211 connects the fixed seats 121 to the bottom of the cargo vehicle body 1. The torsion member 13 has a rotating shaft 122, and the torsion member 13 is rotatably connected to the fixed seats 121 with the rotating shaft 122 as the axis. The first reinforcing rib 1211 increases the structural strength of the fixed seat 121 in the vertical direction and optimizes the torque transmission of the rotating shaft 122 in the vertical direction in the fixed seat 121.

[0029] A second reinforcing rib 111 is connected between the intermediate component 31 and the bottom surface of the cargo vehicle body 1. The second reinforcing rib 111 is configured to be parallel to the telescopic rod 32. The parallel arrangement of the second reinforcing rib 111 and the telescopic rod 32 optimizes the force transmission path, prevents the buffer assembly 3 from twisting under force, and enhances the rigidity and reliability of the buffer system.

[0030] It also includes an upper tube 4 and a rear upper fork tube 5. The upper tube 4 is U-shaped and connects to the rear upper fork tube 5. A traction tube 123 is provided around the perimeter of the cargo vehicle body 1, and both ends of the upper tube 4 are connected to the traction tube 123. The riser is located within the U-shaped area of ​​the upper tube 4. The traction tube 123, the upper tube 4, and the rear upper fork tube 5 are connected together to effectively prevent the cargo vehicle body 1 from experiencing horizontal bumps and loosening due to large inertia during the transportation of goods.

[0031] The cargo vehicle body 1 includes a chassis 11 and a cargo box 12. The cargo box 12 is mounted on the chassis 11 and has a flange 124. At least two support seats 112 are provided on the outer side of the chassis 11. Support pipes 113 are provided on the support seats 112. The support pipes 113 press the traction pipes 123 against the flanges 124. The traction pipes 123 can also be fixedly connected to the flanges 124, which can effectively prevent the cargo box 12 from vertically bumping and loosening due to large inertia during the transportation of goods.

[0032] A reinforcing tube 1131 is connected between the two support tubes 113. The reinforcing tube 1131 generally takes into account the stability in both the horizontal and vertical directions. It is inclined between the two support tubes 113 to form two triangular stable structural areas. At the same time, it also strengthens the connection between the chassis 11 and the carriage 12, which is suitable for heavy loads or complex road conditions.

[0033] The chassis 11 is provided with a first reinforcing beam 114 and a second reinforcing beam 115. The intermediate component 31 is located on the first reinforcing beam 114. The second reinforcing rib 111 is connected to the first reinforcing beam 114, and the second reinforcing beam 115 is perpendicularly connected to the first reinforcing beam 114. The first reinforcing beam 114 evenly distributes the load of the telescopic rod 32 in the buffer assembly 3 to the left and right sides of the chassis 11. The second reinforcing beam 115 evenly distributes the load between the linkage 23 and the intermediate component 31 on the front and rear sides of the vehicle body, avoiding local stress concentration and extending service life. The storage board 125 is detachably installed in the compartment 12, which facilitates the classified storage of items, improves the space utilization of the compartment 12, and its detachable design facilitates cleaning and maintenance.
