Embodiment 1

[0021] see figure 1 , 2 with image 3 . A corner connection device includes a base 10 , a sleeve 20 , a tension spring 30 , a sliding block 40 , a bayonet pin 50 , a sliding pin 60 , a pressing block 70 and a compression spring 80 .

[0022] The lower end of the sleeve 20 is connected to the base 10 through a pin. The sleeve 20 can be turned over at a certain angle with the pin axis as the axis, so as to realize the change of the folded state.

[0023] The sliding block 40 is arranged inside the casing 20, the bayonet pin 50 is fixed at the lower part of the movable block, and the sliding pin 60 is fixed at the upper part of the movable block. The bayonet pin 50 is used to limit the relative position of the base 10 and the sleeve 20 , realize locking the position of the flipped sleeve 20 , and determine the two states after the frame is folded. The sliding pin 60 is used to fit the sliding joint 40 on the bushing 20 and to ensure a sliding engagement with the bushing 20 ....

Embodiment 2

[0032]A folding vehicle frame includes a lower cross frame, a front stand and a corner connecting device. The corner connection device is the connection device of the present invention. The base 10 of the corner connection device is fixed on the front end of the lower cross frame, and the upper end of the sleeve 20 is fixedly connected to the lower end of the front stand. In this embodiment, the lower cross frame is a pedal frame of a folding bicycle. A front fork is installed at the front end of the front stand.

Embodiment 3

[0034] The present invention also provides a foldable bicycle or an electric bicycle equipped with the above frame.

[0035] In summary, the present invention has high stability and is convenient to use. The safety ejector rod 90 in the present invention can prevent the accidental sliding of the pressing and sliding movable block 40 when the pressing movable block 70 is not pressed, resulting in a change in the locked state, avoiding potential safety hazards and making the safety more reliable.
