Example 2:
in this embodiment, the specific structural design of the car door closing in-place detection device 7 is performed on the basis of embodiment 1, and other structures are not changed.
As shown in fig. 2, in order to detect whether the car door 6 is closed in place by the car door closing in-place detection device 7, the design is as follows: the car door closing in-place detection device 7 comprises: the car door closing position detecting device comprises a mounting shell 71, an elastic sheet 72, a conductive piece 73 and an extrusion rod 74, wherein the mounting shell 71 is fixed relative to one of the car doors 6, the elastic sheet 72 and the conductive piece 73 which are spaced from each other are mounted in the mounting shell 71, the elastic sheet 72 and the conductive piece 73 are made of conductive materials, one end of the elastic sheet 72 is mounted on the mounting shell 71, the other end of the elastic sheet 72 extends towards the conductive piece 73 and acts on one end of the extrusion rod 74, the extrusion rod 74 can move in a direction parallel to the movement direction of the car door relative to the car door where the extrusion rod 74 is located, the other end of the extrusion rod 74 penetrates through the mounting shell 71 and acts on the other car door in the car door 6, the extrusion rod 74 is used for extruding the elastic sheet 72 to be in electrical contact with the conductive piece 73 when the two car. The door leaf is suspended on a slide on the car, on which a mounting shell 71 is fixed, which slide can move in the horizontal direction relative to the car.
In order to facilitate replacement of the spring plate 72, the mounting shell 71 includes; the base 711 is fixed on the door leaf, the base 711 is recessed to form a groove, the conductive piece 73 is installed on the inner wall of the groove, the groove is sealed by the rotating cap 713, the rotating cap 713 is in threaded connection with the base 711, a slot is formed in the wall of the groove, one end of the elastic piece 72 is inserted into the slot from the direction of the rotating cap 713, the fixed column 712 inserted into the elastic piece 72 is installed on the inner wall of the slot, and the rotating cap 713 limits the elastic piece 72 to be separated from the slot and the fixed column 712. Because the elastic sheet 72 is often squeezed and then returns to the original shape, the elastic sheet 72 is made of elastic conductive metal materials, the elastic sheet 72 loses elasticity for a long time, and therefore deformation and damage cannot be caused, the elastic sheet 72 is far away from the conductive piece 73 when the door leaf is not closed, a door leaf closing error signal is sent out forever, even if the door leaf is opened, a closing in-place signal is sent out, misjudgment can be caused, safety accidents occur, the function of closing the door to the jo position device 7 can still be achieved, and therefore the elastic sheet 72 needs to be replaced. In this embodiment, the elastic sheet 72 is pressed tightly in the slot by the rotating cap 713 in normal operation, and the fixing column 712 prevents the elastic sheet 72 from being separated from the non-rotating cap 713, so that the elastic sheet 72 can be naturally bent when the elastic sheet 72 is squeezed. When the rotary cap 713 is rotated, the slot can be opened, the elastic sheet 72 can be pulled out from the fixed column 712 and the slot, and the convenient disassembly can be realized only by rotating the rotary cap 713 and pulling the elastic sheet 72. The installation is also very convenient, and only the rotation cap 713 is rotated and the spring piece 72 is pulled.
The pressing lever 74 includes: a rod body 741, a nut 742, the rotating disc 743 and the limiting part 744, the rod body 741 penetrates into the groove, the rod body 741 can move relative to the installation shell 71, the rod body 741 penetrates through the rotating cap 713, the end portion of the rod body 741, which protrudes out of the installation shell 71, is a hemispherical structure, the rod body 741 and the door leaf are prevented from being damaged when the rod body 741 collides with the door leaf, the end portion of the rod body 741, which is located in the groove, is recessed to form a mounting groove, the inner wall of the mounting groove is in threaded connection with the nut 742, the rotating disc 743 penetrates through the nut 742, one side of the rotating disc 743 is in contact with the elastic sheet 72, the other side of the rotating disc 743 is in threaded connection with the limiting part 744, the limiting part 744 is arranged in the groove, the limiting part 744 can rotate in the groove, the rotating disc 743 can rotate relative to the nut 742, the limiting part. Since the pressing rod 74 needs to be in contact with the elastic sheet 72 in the process of rotating the rotating cap 713, in order to avoid damage to the elastic sheet 72 and the pressing rod 74 caused by the rotation of the pressing rod 74 relative to the elastic sheet 72 and thus influence the detection accuracy of the in-place device 7, the rotating disc 743 is designed to rotate relative to the rod body 741, the friction force when the rotating disc 743 is in contact with the elastic sheet 72 is reduced, meanwhile, more or less friction force exists between the rotating disc 743 and the elastic sheet 72, and in order to avoid influence on the detection accuracy after long-term friction and abrasion of the rotating disc 743, the rotating disc 743 is designed to be detachably connected.
Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
