[0002] Tricycles are widely used in daily life. Most tricycle frames on the market use an integrated structural design, with the front and rear of the frame connected by a curved beam. The curved beam is mostly bent or has an arc shape.

[0003] When users assemble the bike themselves, differences in skill level and experience may lead to inconsistent assembly quality. Furthermore, most frames have too many parts and numerous installation steps, which can easily lead to errors in the installation process, wasting time and effort. Utility Model Content

[0004] The purpose of this invention is to provide an easy-to-assemble modular electric tricycle frame to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a U-shaped frame, with a front beam connected to the top of the U-shaped frame, a sleeve connected to the top of the front beam, a pedal connected to one side of the U-shaped frame, a side plate connected to one side of the pedal, a support plate connected to one side of the side plate, and the other end of the support plate connected to the top of the pedal. Fixing mechanisms are connected to both sides of the U-shaped frame, with a front support rod connected to the top of each fixing mechanism. A fixing hole is provided at the bottom of one side of the front support rod, a crossbeam connected to the top of the front support rod, and vertical beams connected to both ends of one side of the crossbeam.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-3 This utility model provides a technical solution, including a U-shaped frame 1, a front beam 2 connected to the top of the U-shaped frame 1, a sleeve 3 connected to the top of the front beam 2, a pedal 6 connected to one side of the U-shaped frame 1, a side plate 7 connected to one side of the pedal 6, a support plate 8 connected to one side of the side plate 7, and the other end of the support plate 8 connected to the top of the pedal 6. Fixing mechanisms 9 are connected to both sides of the U-shaped frame 1, a front support rod 10 is connected to the top of the fixing mechanism 9, a fixing hole 101 is opened at the bottom of one side of the front support rod 10, a crossbeam 11 is connected to the top of the front support rod 10, vertical beams 12 are connected to both ends of one side of the crossbeam 11, a closing plate 15 is connected to one end of the U-shaped frame 1, a connecting plate 16 is connected between the pedal 6 and the closing plate 15, and a plug ring 17 is connected to one side of the U-shaped frame 1.

[0019] The top of the U-shaped frame 1 is connected to both sides of the front beam 2 with a barrier 4. One side of the front beam 2 is connected to the top of the U-shaped frame 1 with a diagonal brace 5. The purpose of the barrier 4 is to effectively prevent objects or people from falling from both sides of the U-shaped frame 1. This protective measure is especially important in dynamic environments (such as when the vehicle is in motion).

[0020] A rear support rod 13 is connected to the bottom of the middle of the vertical beam rod 12, and a C-shaped fixing plate 14 is connected to one side of the tail end of the U-shaped frame 1. The surface of the rear support rod 13 is slidably connected to the inside of the C-shaped fixing plate 14. The function of this slidable connection design between the rear support rod 13 and the C-shaped fixing plate 14 is to facilitate the operator to install the frame.

[0021] The fixing mechanism 9 includes a mounting base 91 connected to and disposed inside one side of the U-shaped frame 1. A cavity 92 is formed inside the mounting base 91. A spring 93 is connected to one side of the cavity 92. A rectangular plate 94 is connected to one end of the spring 93. Two sets of support rods 95 are connected to one side of the rectangular plate 94. A limit block 96 is connected to one side of the rectangular plate 94, corresponding to a fixing hole 101 between the support rods 95. The limit block 96 is set with an inclined surface corresponding to the fixing hole 101. A pressing block 97 is connected to one end of each support rod 95. The top of the mounting base 91 has a through hole 98 corresponding to the bottom of the front support rod 10. Its function is to provide sufficient support force for the support rod 95 when it is subjected to external force through the cooperation of the spring 93 and the rectangular plate 94, so as to ensure that the front support rod 10 is firmly fixed in the required position. The setting of the limiting block 96, especially its inclined surface design corresponding to the fixing hole 101, allows the support rod 95 to move smoothly when it is inserted into the fixing hole 101, and provides a reliable limiting effect after reaching the predetermined position, preventing the front support rod 10 from being accidentally loosened.

[0022] Two sets of insert rod rings 17 are connected to the inner tail end of the U-shaped frame 1. Their function is to provide additional support and fixation in scenarios where large loads or stresses need to be borne.

[0023] Two sets of connecting rods 18 are provided between the vertical beams 12. The function of the connecting rods 18 is to firmly connect the adjacent vertical beams 12 together, forming a more stable overall structure.

[0024] Multiple mounting plates 19 are provided on both sides of the vertical beam 12 and the connecting rod 18. Each mounting plate 19 has mounting holes at its top. The design of the mounting plates 19 allows for easy connection of various accessories, equipment, or additional structures to the vertical beam 12 and the connecting rod 18. The mounting holes provide standardized interfaces for these connections, making the installation process more convenient and efficient.

[0025] Working principle: The user first installs two vertical beams 12 on one side of the horizontal beam 11 with bolts, then installs two connecting rods 18 between the vertical beams 12, and then installs the closing plate 15 at the tail end of the guide U-shaped frame 1 with bolts. Next, the connecting plate 16 is installed on one side of the closing plate 15. Then, the pedal 6 is installed between the front ends of the U-shaped frame 1. Afterwards, the bottom end of the front support rod 10 is aligned with the through hole 98, and the rear support rod 13 is aligned with the C-shaped fixing plate 14 and pressed down directly. Simultaneously, the front support rod 10 moves downwards... When the limit block 96 is in the through hole 98, because one side of the limit block 96 is inclined, it will move backward due to the compression of the front support rod 10. Then, the rectangular plate 94 will compress the spring 93 due to the backward movement of the limit block 96. When the fixing hole 101 below the front support rod 10 reaches the bottom of the limit block 96, the kinetic energy of the spring 93 will push the rectangular plate 94. The rectangular plate 94 will drive the limit block 96 to be inserted into the fixing hole 101, completing the fixation and then completing the installation. The whole installation process becomes easier to assemble and disassemble.
