Problems solved by technology
[0007] However, due to the increase of the angle between the axis line of the parking rod and the left / right center plane of the vehicle frame, when the parking rod is in the above-mentioned folded position, it interferes with the bottom bracket of the vehicle frame. The pivoting path of the crank, or collision with the bike's chain
Therefore, in the current commercially available parking frames for installation on the bottom bracket of the frame, the angle between the axis line of the parking rod and the left / right center plane of the frame is limited within a certain angle. , so that the upright stability of the bicycle equipped with this kind of parking frame cannot be improved
In addition, some operators adopt the method of lowering the position of the parking frame to avoid the above-mentioned problems such as interference or collision. This method will make the distance between the parking frame and the ground too short, and it is easy to get in contact with the ground when the bicycle is moving. Landforms or obstacles cause collisions, causing safety issues

The invention discloses a parking frame for a bicycle, which comprises a joint seat and a parking pole. The joint seat is jointed on the frame of the bicycle; and the parking pole can pivot from a supporting position to a folding position relatively to the joint seat. When the parking frame pivots from the supporting position to the folding position, an included angle between the parking frame and the left / right central plane of the bicycle frame gradually becomes smaller, and when the parking frame reaches the folding position, the included angle becomes so small that the parking pole is not interfered with the pivoting route of a bicycle crank and a chain of the bicycle; on the contrary, when the parking pole pivots from the folding position to the supporting position, an included angle between the parking pole and a central plane gradually becomes bigger, and when the parking pole reaches the supporting position, the included angle between the parking pole and the central plane becomes so big that the bicycle can be firmly erected on the ground.
Description
technical field [0001] The invention relates to a device for supporting a bicycle on the ground, in particular to a bicycle parking frame. Background technique [0002] When the bicycle is parked, it is generally supported on the ground by a parking frame combined with it on its vehicle frame. The current parking frames all have a coupling seat combined on the vehicle frame, and a parking bracket that is pivotally connected to the coupling seat and can pivot back and forth between a support (stand) position and a folded position (fold). car pole. Viewed from the side of the bicycle, the parking rod is approximately perpendicular to the ground when it is in the supporting position, and is approximately parallel to the ground when it is in the folded position. When this parking rod is in the support position, its free end can be in contact with the front and rear wheels of the bicycle on the ground jointly, so that the bicycle forms three contact points with the ground, and ...
