The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0025] See also Figure 1-5 The utility model provides a technical solution:

[0026] A new bicycle rack, comprising:

[0027] The upper beam 20 includes an upper front beam 21 and an upper rear beam 22, wherein the upper front beam 21 is hinged to the upper rear beam 22, and a connecting component 23 is provided between the upper front beam 21 and the upper rear beam 22, wherein the connecting component 23 includes two states, namely, a locked state and an open state. The upper front beam 21 and the upper rear beam 22 can be locked in the locked state, and the upper front beam 21 and the upper rear beam 22 can be folded in the open state, thereby achieving complete folding of the upper beam 20;

[0028] A rear fork 40, which is fixedly disposed at the other end of the upper rear beam 22 away from the upper front beam 21, and is used for mounting the rear wheel;

[0029] A front fork 30, which is rotatably arranged at the other end of the upper front beam 21 away from the upper rear beam 22, and is used for mounting the front wheel;

[0030] The stand pipe 10 is fixedly arranged on the upper rear beam 22. The upper end of the stand pipe 10 is used for mounting a seat, and the lower end is used for mounting a pedal.

[0031] In the above, by setting the connecting component 23, when the connecting component 23 is in the locked state, the upper front beam 21 and the upper rear beam 22 can be locked, and when in the open state, the upper front beam 21 and the upper rear beam 22 can be folded, thereby achieving complete folding of the upper beam 20, further realizing the storage of the entire bicycle and reducing the floor space occupied by the bicycle when not in use.

[0032] Specifically, Figure 3As shown in: the connecting assembly 23 includes a rotating plate 234 rotatably connected to the upper rear beam 22 and a locking block 232 fixedly arranged on the upper front beam 21, and the side of the rotating plate 234 is fixedly connected with two oppositely arranged locking plates 233, and the locking block 232 is arranged on the rotation path of the locking plate 233. In this way, when the upper front beam 21 and the upper rear beam 23 are unfolded, the locking block 233 is driven to rotate by the rotating plate 234. When the locking plate 233 abuts against the locking block 232, the upper front beam 21 and the upper rear beam 22 are locked.

[0033] Specifically, Figure 1-2 As shown in : the front end of the upper front beam 21 is fixedly connected to the head pipe 50, and the interior of the head pipe 50 is rotatably connected to the front fork 30.

[0034] Specifically, Figure 4 As shown in the figure: the locking plate 233 is arranged in an L shape, and the outer part of the locking block 232 is symmetrically provided with bosses 235, so that the locking plate 233 is hooked on the locking block 232 to achieve close contact between the locking plate 233 and the locking block 232.

[0035] Specifically, Figure 3 As shown in the figure: the locking groove 231 is L-shaped, and the bottom end of the locking groove 231 extends from the bottom of the upper front beam 21, and the locking block 232 is arranged inside the locking groove 231, which is convenient for the user to drive the rotating plate 234 to rotate and easy to operate.

[0036] Working principle: When in use, the rotating plate 234 rotates, thereby driving the locking plate 233 to abut against the locking block 232, so that the upper front beam 21 and the upper rear beam 22 are locked as a whole. After use, the user grabs the rotating plate 234 from the bottom of the locking groove 231, and rotates it outward with force to separate the locking block 232 and the locking plate 233, and rotates the upper front beam 21, so that the bicycle frame can be completely folded, and the overall storage of the bicycle can be further realized, reducing the floor space occupied by the bicycle when not in use.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
