As shown in fig. 1 and 2, an embodiment of the present invention discloses a stopper and locking mechanism, which includes a frame 1, a stopper guide slideway 2, a slide rail 3, a driving assembly, a door carrying frame 4, a connecting rod 5, a driven member 6 and a limiting member 7, wherein the stopper guide slideway 2 is horizontally fixed at a position near the bottom of the frame 1; the slide rail 3 is connected with the longitudinal rail of the frame 1 in a sliding manner and is horizontally arranged, namely the slide rail 3 can slide along the vertical direction of the frame 1; two ends of the driving component are rotationally connected with the frame 1; the door carrying frame 4 is connected with the slide rail 3 in a sliding manner, namely the door carrying frame 4 can horizontally slide along the slide rail 3; the driving component is connected with the door carrying frame 4 through a connecting rod 5; the driven piece 6 is connected with the plug pull guide slideway 2 in a rolling way, and the driven piece 6 is connected with the door carrying frame 4; the limiting member 7 is fixed on the frame 1 and is close to the extending end of the active component. According to the invention, the driving component is in transmission connection with the portal frame 4 which is in rotation connection with the driven component 6 through the connecting rod 5, on one hand, the driving component is prevented from being specially customized and high-pair contact is formed, only the existing screw rod structure is used, the operation is more stable, the noise is lower, and the service life is longer; on the other hand, passive locking is realized, the structure is simple and reliable, the manufacturing cost is low, and the system integration level is high; finally, the conversion rate of the plug tension is improved, and the transmission efficiency is high.
Specifically, the driving component comprises a screw 8 and a nut 9, and two ends of the screw 8 are respectively rotatably connected with the rack 1; the nut 9 is in screw transmission connection with the screw rod 8; one end of the connecting rod 5 is rotationally connected with the nut 9, and the other end of the connecting rod 5 is rotationally connected with the door carrying frame 4.
Specifically, the driven member 6 is a guide wheel, the guide wheel is connected with the plug pull guide slideway 2 in a rolling or sliding manner, and correspondingly, the guide wheel is connected with the door carrying frame 4 in a rotating or fixed manner.
Specifically, the plug guide chute 2 comprises a horizontal section and a downward-inclined bent section which are connected into a whole.
The working principle of the invention is as follows:
the screw 8 rotates to further drive the nut 9 to translate along the axial direction of the screw 8, the nut 9 drives the connecting rod 5 to drive the door carrying frame 4 to move, namely the nut 9 and the door carrying frame 4 are in transmission connection through the connecting rod 5, the door carrying frame 4 transversely translates along the sliding rail 3, meanwhile, the door carrying frame 4 rolls along the plug-pull guide slideway 2 under the action of the guide wheel, namely, a space cam motion pair is formed, when the position of the limiting part 7 is close, the track of the plug-pull guide slideway 2 (calculated by using the degree of freedom, the degree of freedom of a plug-pull and door-locking mechanism is equal to the number of power sources and is fixed track motion) is limited and guided, the sliding rail 3 longitudinally translates along the rack 1, at the moment, the included angle between the connecting rod 5 and the door carrying frame 4 in the sliding direction is increased, when the nut 9 is in mechanical limiting contact with the limiting part 7, at the moment, the included angle between the connecting rod 5 and the door carrying frame 4 in the sliding direction is greater than or equal to 90 degrees, a horizontal leftward component force can be generated, the nut 9 and the closer to the limiting part 7, and the closer to the stop point, and the passive locking connecting rod transmission is formed, and the dead point is realized. It is worth mentioning that in practical products, the sealing force of the rubber strip of the sliding plug door, the leaning force of passengers and the auxiliary elastic structure can realize the locking pretightening force.
Certainly, in actual use, the lead screw 8 is driven by a driving motor, which is the prior art, and is not described herein again, when the nut 9 is in mechanical limit contact with the limiting part 7, the driving motor stops rotating (of course, in order to improve the intelligent automation level, a sensor is installed on the limiting part 7, and once the contact with the nut 9 is monitored, information is transmitted to the controller, so as to control the driving motor to stop rotating).
In the process, the included angle between the sliding direction of the connecting rod 5 and the door carrying frame 4 is large during door plugging, the included angle is small in the horizontal moving process, and through stress decomposition analysis, the transmission force of the nut 9 is converted into the plug pulling force in a high proportion in the door plugging movement or horizontal moving process, so that the transmission efficiency is very high.
The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other. The device disclosed by the embodiment corresponds to the method disclosed by the embodiment, so that the description is simple, and the relevant points can be referred to the method part for description.
