[0024] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals.

[0025] like Figure 1-5As shown, a quick-release towable bicycle includes: a frame 1, which is specifically a human-powered bicycle. The frame 1 includes a front fork 2 for connecting to the front wheel. The front fork 2 includes two fork arms 3 symmetrically arranged on both sides of the front wheel. Each fork arm 3 has a mounting position 4. The two mounting positions 4 are detachably connected to the front wheel. Specifically, the front wheel is mounted between the two fork arms 3 and is rotatably connected to the front wheel through the mounting positions 4 on both sides.

[0026] It also includes a towing device 5, which is detachably connected to two mounting positions 4. A connection position 6 is formed on the towing device 5, which is used to connect a driving vehicle. In this embodiment, the driving vehicle is specifically a motorized bicycle, and the rear end of the motorized bicycle has a threaded hole for connecting the connection position 6.

[0027] During use, when the vehicle can no longer be ridden, the front wheel can be separated from the mounting position 4, and the towing device 5 can be connected to the drive wheel. The mounting position 4 can be connected to the towing device 5, and the vehicle body 1 can be towed by driving the vehicle. Due to the separation design of the front wheel, the distance between the drive vehicle and the vehicle body 1 is closer, which can improve the safety during the towing process and also improve the stability of the vehicle body 1 itself.

[0028] The disassembled front wheel can be tied to position 2 of the front fork with straps to achieve joint towing.

[0029] Preferably, each of the two fork arms 3 has a mounting groove 7 at the corresponding mounting position 4, and the mounting groove 7 is specifically open on the lower side.

[0030] It also includes a quick-release assembly, which includes a quick-release rod 8 and a quick-release nut 9. One end of the quick-release rod 8 passes through two mounting slots 7 and is connected to the quick-release nut 9. The quick-release rod 8 is used to rotate with the front wheel. When the front wheel is installed, the quick-release rod 8 passes through a hole on the front wheel and rotates with the front wheel.

[0031] The quick-release assembly allows for rapid assembly and disassembly of the front wheel and front fork 2, facilitating towing.

[0032] Preferably, a constraint groove 10 is provided on one side of the fork arm 3 corresponding to the mounting groove 7. The constraint groove 10 is used to engage the quick-release nut 9 to restrict the quick-release rod 8 from separating from the mounting groove 7 along the groove opening, thereby ensuring the stability of the quick-release assembly after connection.

[0033] Preferably, the towing device 5 includes two locking seats 11, which are rotatably locked into the mounting groove 7.

[0034] The relative swinging of the front fork 2 and the towing device 5 can be achieved by rotating the connector 11 and the mounting slot 7, thereby improving the mobility of the vehicle body 1. When facing potholes, the swinging of the vehicle body 1 can improve the stability of the vehicle body 1 and reduce the damage to the vehicle body 1.

[0035] Preferably, a through hole 12 is formed between the two snap-fit ​​seats 11, and the through hole 12 is used for the quick-release lever 8 to pass through.

[0036] The quick-release assembly enables rapid installation and positioning of the trailer 5, thereby preventing the snap-fit ​​seat 11 from separating from the mounting slot 7 during towing and ensuring the stability of the trailer.

[0037] Preferably, the towing device 5 includes a fixed frame 13, with connecting plates 14 connected to both sides of the fixed frame 13, and the connecting position 6 is a hole 15 provided at the end of the connecting plate 14 away from the fixed frame 13.

[0038] The connecting plate 14 facilitates connection to the rear end of the power wheel while maintaining a distance from the rear wheel of the power vehicle to avoid adverse effects on the driving of the power wheel itself.

[0039] Furthermore, the number of holes 15 corresponding to the connecting plate 14 on one side is at least 2, specifically 2 in this embodiment.

[0040] Furthermore, the end of the connecting plate 14 is fixedly connected to the fixing frame 13 by bolts, thereby realizing the disassembly and assembly of the connecting plate 14 and the fixing frame 13, so as to facilitate the replacement of the length of the connecting plate 14 to adapt to different models of power vehicles.

[0041] Preferably, the front fork 2 is provided with a limiting block 16, which is used to abut against the towing device 5 to limit the rotation angle of the towing device 5 relative to the front fork 2.

[0042] The setting of limit block 16 can prevent the vehicle body 1 from swinging too much relative to the power vehicle, which would lead to instability.

[0043] Preferably, the towing device 5 includes a limiting seat 17, which is used to abut against the inner wall of the fork 2 to restrict the movement of the fork 2 along the axial direction of the locking seat 11, thereby cooperating with the quick-release structure and the locking groove 10 to achieve a single degree of movement of the fork 2 relative to the locking seat 11.

[0044] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
