The motorized locating pin 13 of the present invention may be manufactured by MISUMI, Inc. under model number BKFDA 1-P.
The working principle of the utility model is as follows:
under the normal driving state, as shown in fig. 10, the electric positioning pins 13 distributed on both sides of the base 10 are clamped in the clamping slots 5-4 on the sleeve 5 to limit the movement of the sleeve 5, so as to limit the movement of the front leg part to ensure the stability of the baby carriage during the normal driving, and meanwhile, the spring 15 is under the semi-compression state during the normal driving.
Before the escalator is used to go upstairs, as shown in fig. 11, firstly, the switch of the electric positioning pin 13 is pressed, the electric positioning pin 13 placed in the base 10 is retracted into the base 10 at the extending end of the electric positioning pin 13 through an internal circuit, the front stairs of the baby carriage are gradually lifted along with the operation of the escalator, when the stairs are lifted, the upward force causes the mounting rod 6 to compress the spring to move upwards, meanwhile, the guide rod 5-2 moves backwards for a certain distance in the guide cylinder a17 to drive the front legs at two sides of the carriage body to shift backwards for a certain distance, in the process, the guide sheet 5-1 slides and positions in the guide ring 6-1, the mounting rod 6 slowly rises under the buffer of the spring 15 to reduce the impact (the spring 15 is changed from a semi-compression state to a compression state), and the vertical rod 8 and the special-shaped connecting rod 9 rotate when the mounting rod 6 is lifted, so that the vertical rod 12 does not move (the rear leg is positioned at the next step), in the process, the body 1, the base 10, the vertical rod 12 and the like are not moved, so that the whole baby carriage is kept horizontal, the baby carriage ascends along with the escalator, when the baby carriage goes upstairs, the front step and the rear step on the escalator start to be leveled, the rear step gradually ascends relative to the front step, the height of the mounting rod 6 is kept unchanged, the height difference of the front leg and the rear leg is reduced slowly along with the descending of the steps under the restoring force of the spring 15, in the process, the front leg, the straight connecting rod 8 and the special-shaped connecting rod 9 restore positions, the spring 15 is converted into a semi-compression state from the compression state, the switch of the electric positioning pin 13 is pressed to be popped to the clamping groove 5-4 to clamp the sleeve 5 to be immovable, and the baby carriage is restored to a normal running state.
Similarly, when the escalator is used to go downstairs, as shown in fig. 9, the switch of the electric positioning pin 13 is first pressed, the electric positioning pin 13 placed inside the base 10 is retracted into the base 10 through the internal circuit, the front stairs of the stroller are gradually lowered along with the operation of the escalator, when the stairs are lowered, the mounting bar 6 is moved downward by the restoring force generated by the spring 15 in the semi-compressed state, and at the same time, the guide bar 5-2 is moved backward by a certain distance in the guide cylinder a17 and drives the front legs at both sides of the stroller body to be shifted backward by a certain distance, during which the guide piece 5-1 slides and positions in the guide ring 6-1, and the mounting bar 6 is slowly lowered under the buffer of the spring 15 to reduce the impact (the spring 15 is changed from the semi-compressed state to the free state), and at the same time, the guide bar 6 is rotated by the straight link 8 and the special-shaped link 9 so that the mounting bar 6 is not moved (the rear legs are positioned on the upper vertical bars 12) when the guide bar 6 is lowered One-step), the body 1, the base 10, the vertical rod 12 and the like are fixed in the process, so that the whole baby carriage is kept horizontal, the baby carriage descends along with the escalator, when the baby carriage descends downstairs, the next step descends relative to the previous step, the height of the guide rod 6 is unchanged, the other parts descend horizontally under the action of the gravity of the baby carriage (the spring 15 is compressed from a free state to a semi-compressed state), each part of the baby carriage returns to an initial position, the electric positioning pin 13 is pressed to be popped out to the clamping groove 5-4 to clamp the sleeve 5 immovably, and the baby carriage returns to a normal running state.
When the baby carriage goes up and down the escalator, the baby carriage can easily finish the action of going up and down stairs by using the escalator under the unpowered condition through the cooperation of the parts.
