[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 The handlebar folding device comprises a locking seat 1 and a connecting seat 2. The locking seat 1 can be detachably mounted on a handlebar front rod 3. The connecting seat 2 is used to connect a front wheel support rod. A hinge portion 4 is provided on the outer wall of the locking seat 1. A hinge 5 is provided on the outer side of the connecting seat 2. The locking seat 1 and the connecting seat 2 are hingedly connected through the hinge 5 and the hinge portion 4. A movable locking handle 6 is provided on the outer wall of the connecting seat 2 and on the side corresponding to the hinge 5. The movable locking handle 6 locks the locking seat 1 and the connecting seat 2. The handlebar folding device formed by the hinged locking seat 1 and the connecting seat 2 and the movable locking handle 6 in this solution makes the bicycle handlebar foldable, which solves the problem that the handlebar of a traditional bicycle has a fixed structure, occupies a large space, and is very inconvenient to store and transport.

[0023] like Figure 4-6 As shown, the movable locking handle 6 includes a first hinge seat 61 arranged on the outer wall of the connecting seat 2 and a second hinge seat 62 arranged on the outer wall of the locking seat 1. The first hinge seat 61 corresponds to the second hinge seat 62. A handle 67 is hinged on the first hinge seat 61, and a telescopic rod 63 is hinged on the second hinge seat 62. A rotating shaft 64 is rotatably connected to the inner upper middle part of the handle 67, and one end of the telescopic rod 63 away from the second hinge seat 62 is fixedly connected to the rotating shaft 64. A limiting member 65 is arranged on the handle 67, and a limiting groove 66 is arranged on the rotating shaft 64. The limiting member 65 and the limiting groove 66 are plugged into each other to limit the rotating shaft 64.

[0024] The limiting member 65 includes a mounting block 651 fixedly mounted on the inner upper portion of the handle 67, a limiting rod 652 is arranged between the mounting block 651 and the handle 67 and corresponding to the limiting groove 66, the limiting rod 652 is slidably connected to the mounting block 651 and the handle 67, a spring 653 is fixedly connected to the top of the limiting rod 652, the top of the spring 653 is fixedly connected to the inner top wall of the mounting block 651, a pull rope 654 is arranged on the limiting rod 652, and the pull rope 654 passes through and extends to the outside of the handle 67.

[0025] The movable locking handle 6 can unlock the entire device by pulling the pull rope 654 to make the limit rod 652 move upward and separate from the limit groove 66, which is convenient to operate and effectively improves the unlocking efficiency. The spring 653 presses the limit rod 652 down, and the limit rod 652 blocks the top of the rotating shaft 64, which can prevent the telescopic rod 63 and the handle 67 from rotating. Then the telescopic rod 63 and the handle 67 fasten the locking seat 1 to the connecting seat 2, so that the locking seat 1 and the connecting seat 2 are tightly fastened during normal driving, effectively improving driving safety.

[0026] In addition, an opening 7 is provided on the outer wall of the connecting seat 2, and a bolt locking hole 8 is provided on the outer wall of the connecting seat 2 and near the opening to facilitate the installation and locking of the front rod of the wheel. A card slot 9 is provided on the hinge 4, and an elastic card ball 10 is provided on the hinge 5 corresponding to the card slot 9. When the locking seat 1 and the connecting seat 2 are folded, the elastic card ball 10 (which can be composed of a card ball and an elastic member) is engaged with the card slot 9, so that the folded handlebar can maintain a stable folded state with the frame, effectively improving the storage and transportation stability. The handle 67 is Figure 5 The viewing angle rotates counterclockwise with the second hinge seat 62 as the center and the maximum opening and closing angle is ninety degrees.

[0027] The motion state of the handlebar folding device of this scheme is as follows:

[0028] State before folding: the spring 653 presses the limiting rod 652 down and engages with the limiting groove 66 to limit the rotating shaft 64 to prevent the handle 67 and the telescopic rod 63 from rotating, thereby fastening the handle 67 and the telescopic rod 63 to the locking seat 1.

[0029] Folding process: pull the pull rope 654, then drive the limit rod 652 to move upward, the spring 653 is compressed, and then the limit rod 652 is disengaged from the top of the rotating shaft 64, the handle 67 and the telescopic rod 63 can be rotated, and then the connecting seat 2 and the locking seat 1 are separated.

[0030] Folded state: the card ball 10 is buckled into the card slot 9, that is, it is folded into place and locked.

[0031] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
