[0018] 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.

[0019] Please see Figures 1-4 This utility model provides a technical solution: an adjustable support arm structure for an electric tricycle, including a fixed arm 4, a connecting structure 2 fixedly connected to the outer wall of the fixed arm 4, a fixing bolt 1 slidably connected to the inner wall of the connecting structure 2, a locking nut 3 threadedly connected to the outer wall of the fixing bolt 1, a telescopic cavity 5 slidably connected to the outer wall of the fixed arm 4, a telescopic arm 6 slidably connected to the outer wall of the telescopic cavity 5, and an adjustment structure 7 fixedly connected to the outer wall of the telescopic arm 6. The fixed arm 4 serves as a basic component, and the connecting plate 21 of its outer wall connecting structure 2 is slidably connected to the fixing bolt 1 through a connecting hole 22. The fixing bolt 1, in conjunction with the locking nut 3, allows the connecting structure 2 to be installed at the corresponding port of the fixed arm 4. The elongated hole 23 in the wall of the connecting plate 21 enables short-distance adjustment. In use, after the bolt is passed through the elongated hole 23, the electric tricycle connecting component is clamped with the nut. After loosening the bolt, the position of the fixed arm 4 can be finely adjusted within the range of the elongated hole 23, and then the bolt is tightened to fix it.

[0020] The inner wall of the fixed arm 4 is slidably connected to the outer wall of the fixed bolt 1, and the outer wall of the fixed arm 4 is in contact with the outer wall of the telescopic arm 6. The connecting structure 2 includes a connecting plate 21, a connecting hole 22 is provided in the wall of the connecting plate 21, and elongated holes 23 are symmetrically provided in the wall of the connecting plate 21. The inner wall of the connecting plate 21 is slidably connected to the outer wall of the fixed bolt 1 through the connecting hole 22. The outer wall of the fixed arm 4 is slidably connected to the telescopic cavity 5, and the telescopic cavity 5 is slidably connected to the telescopic arm 6. This structure enables long-distance adjustment. When it is necessary to change the overall length of the support arm, the telescopic arm 6 is pushed to slide in the telescopic cavity 5. After reaching the appropriate position, it is fixed by bolt through the hole. This can meet the requirements of different vehicle models or transporting goods of different sizes for the length of the support arm.

[0021] The adjustment structure 7 includes a connecting pipe 71, a fixing sleeve 72 fixedly connected to the inner wall of the connecting pipe 71, a grooved pipe 73 fixedly connected to the inner wall of the connecting pipe 71, and the outer wall of the connecting pipe 71 fixedly connected to the outer wall of the telescopic arm 6. The adjustment structure 7 includes a connecting pipe 71, a fixing sleeve 72, and a grooved pipe 73. The connecting pipe 71 is connected to the telescopic arm 6, and the grooved pipe 73 and other structures can realize angle adjustment. Small angle adjustment can be realized through the corresponding elongated circular hole structure on the telescopic arm 6.

[0022] In use, the electric tricycle utilizes an adjustable support arm structure with multiple components working in tandem to achieve flexible adjustment of the support arm's length and angle. The fixed arm 4 serves as the basic component, and its outer wall connecting structure 2's connecting plate 21 is slidably connected to the fixing bolt 1 via connecting holes 22. The fixing bolt 1, in conjunction with the locking nut 3, allows the connecting structure 2 to be installed at the corresponding port of the fixed arm 4. The elongated hole 23 in the wall of the connecting plate 21 enables short-distance adjustment. During use, after passing the bolt through the elongated hole 23, the electric tricycle's connecting components are clamped using the nut. After loosening the bolt, the position of the fixed arm 4 can be fine-tuned within the range of the elongated hole 23, and then the bolt can be tightened to fix it, making the support arm more flexible in adjusting its position within a small range.

[0023] The outer wall of the fixed arm 4 is slidably connected to the telescopic cavity 5, which in turn is slidably connected to the telescopic arm 6. This structure enables long-distance adjustment. When it is necessary to change the overall length of the support arm, the telescopic arm 6 is pushed to slide in the telescopic cavity 5. After reaching the appropriate position, it is fixed by bolt holes. This can meet the requirements of different vehicle models or transporting goods of different sizes for the length of the support arm, effectively solve the assembly problem, improve the assembly speed, and avoid rework caused by the mismatch of the support arm length.

[0024] The adjustment structure 7 fixed to the outer wall of the telescopic arm 6 includes a connecting pipe 71, a fixing sleeve 72, and a grooved pipe 73. The connecting pipe 71 is connected to the telescopic arm 6, and the grooved pipe 73 and other structures can realize angle adjustment. Small angle adjustment can be achieved through the corresponding elongated round hole structure on the telescopic arm 6. Large angle adjustment requires the coordination between the adjustment hole on the connecting plate 21, the telescopic cavity 5, the telescopic arm 6, and the elongated round hole on the telescopic arm 6. During vehicle maintenance or modification, the arm angle can be adjusted according to actual needs to adapt the arm to different operating scenarios.

[0025] This adjustable support arm structure can be matched with different vehicle models, realizing multiple uses with one arm, improving product utilization, saving costs, and flexibly adjusting the support arm parameters according to different vehicle usage needs and road conditions, thereby improving the versatility and adaptability of the chassis support arm and meeting diverse usage scenarios.
