技术领域 technical field
本发明十字滑块式塞拉门机构涉及的是一种高速列车塞拉门的开关与密封机构，特别适用于地铁或者高速列车的门的开关与密封。The cross slider type sliding door mechanism of the present invention relates to a switch and sealing mechanism of a high-speed train sliding door, and is especially suitable for the opening and closing and sealing of subway or high-speed train doors.
背景技术 Background technique
常见的列车塞拉门是两扇门，实现对开或关的运动，为了实现关门时的密封，就必须增加一个向内的塞拉压紧运动，保证关门后有很好的密封效果。为了实现这一功能，国内外大体可以分为三种不同的机构，第一种是国产机构为代表的，主要延x方向实现门的对开与关，沿y方向实现塞拉运动达到密封，但是延x方向运动的主轴不固定，它同时延y方向移动，因此主轴稳定性稍差，结构尺寸大，占用的空间多。第二种是以国外某公司为代表的机构，延x方向实现门的对开与关，x方向移动的主轴固定，刚性好，塞拉运动是采用了绕x轴旋转的摇杆摆动，带动双摇杆机构实现门的塞拉，其刚性好但尺寸大。第三种机构也是国外某公司为代表的机构，同样延x方向实现门的对开与关，主轴固定，门的塞拉运动是采用了绕z周转动的四杆机构实现门的塞拉密封。The common train plug door is two doors, which realize the movement of opening or closing. In order to realize the sealing when closing the door, an inward plug pressing movement must be added to ensure a good sealing effect after the door is closed. In order to realize this function, there are three different types of mechanisms at home and abroad. The first type is represented by the domestic mechanism, which mainly realizes the opening and closing of the door along the x direction, and realizes the plug movement along the y direction to achieve sealing. However, the main shaft moving along the x direction is not fixed, and it moves along the y direction at the same time, so the stability of the main shaft is slightly poor, the structure size is large, and it takes up a lot of space. The second type is a mechanism represented by a foreign company, which realizes the opening and closing of the door along the x direction. The main shaft moving in the x direction is fixed and has good rigidity. The double rocker mechanism realizes the plugging of the door, which has good rigidity but large size. The third type of mechanism is also represented by a certain foreign company. It also realizes the opening and closing of the door along the x direction, the main shaft is fixed, and the door's plugging movement uses a four-bar mechanism that rotates around the z circle to realize the plugging seal of the door. .
发明内容 Contents of the invention
本发明目的是针对目前常用的塞拉门机构的不足之处，提供一种十字滑块式塞拉门机构，是一种新的塞拉门运动机构，本发明结合了各家的长处，克服了各家的不足形成一种新十字滑块式的塞拉机构，使塞拉门运动更加可靠，尺寸更加紧凑，同时也降低了成本。The object of the present invention is to aim at the deficiencies of the commonly used sliding door mechanisms at present, and to provide a cross slider type sliding door mechanism, which is a new sliding door movement mechanism. The present invention combines the strengths of various companies to overcome A new cross-slider type sliding mechanism is formed to overcome the deficiencies of various companies, which makes the movement of the sliding door more reliable, the size is more compact, and the cost is also reduced.
本发明的十字滑块式塞拉门机构是采取以下技术方案实现：The cross slider type sliding door mechanism of the present invention is realized by adopting the following technical solutions:
十字滑块式塞拉门机构由步进电机、丝杠、丝杠螺母、支座、主轴、十字滑块、导杆、塞拉门体、导向轮、导向槽组成。The cross slider type plug door mechanism is composed of a stepping motor, a lead screw, a lead screw nut, a support, a main shaft, a cross slider, a guide rod, a plug door body, a guide wheel and a guide groove.
主轴固定在支座上，十字滑块的其中一个孔与主轴配合并能延主轴轻松滑动，十字滑块的另一个相互垂直的孔与导杆相配合，塞拉门体与该导杆用螺钉固联，在导杆上装有导向轮，导向轮限制在导向槽内运动，导向槽做成直线加圆弧的形状，当导向轮在十字滑块的带动下沿导向槽的直线部分移动时就带动塞拉门走直线实现门的开与关，当导向轮走到导向槽的圆弧部分时，则带动塞拉门走了一段圆弧从而实现了塞拉运动。其中十字滑块的运动是通过步进电机驱动丝杠旋转，使丝杠螺母作直线移动，丝杠螺母与十字滑块固联，使十字滑块也作直线移动，从而带动塞拉门沿导向槽运动。The main shaft is fixed on the support, one of the holes of the cross slider is matched with the main shaft and can easily slide along the main shaft, the other vertical hole of the cross slider is matched with the guide rod, and the plug door body and the guide rod are connected by screws Fixed connection, the guide rod is equipped with a guide wheel, the guide wheel is limited to move in the guide groove, the guide groove is made into a straight line and arc shape, when the guide wheel moves along the straight line part of the guide groove driven by the cross slider Drive the plug door to go straight to realize the opening and closing of the door. When the guide wheel reaches the arc part of the guide groove, it drives the plug door to walk a section of arc to realize the plug movement. The movement of the cross slider is to drive the screw to rotate through the stepping motor, so that the screw nut moves in a straight line. Groove movement.
工作原理：working principle:
十字滑块式塞拉门机构工作时，步进电机驱动丝杠转动，驱动丝杠螺母作直线移动，丝杠螺母与十字滑块固联，所以使十字滑块沿x轴向移动，从而带动导杆与塞拉门延x方向移动，实现门的开与关，由于导杆与塞拉门体是被动运动，受导向槽的运动限制，导向槽设计成直线加圆弧的几何形状，直线控制门的直线开与关，而圆弧段迫使门走一段圆弧实现门的塞拉复合运动。When the cross slider type sliding door mechanism is working, the stepper motor drives the screw to rotate, and drives the screw nut to move in a straight line. The guide rod and the plug door move along the x direction to realize the opening and closing of the door. Since the guide rod and the plug door are passively moved, limited by the movement of the guide groove, the guide groove is designed as a geometric shape of a straight line plus an arc, and the straight line It controls the straight line opening and closing of the door, and the circular arc section forces the door to walk a circular arc to realize the compound movement of the door.
高速列车塞拉门是用于地铁或者高速列车的门的开关与密封。主要要求开关门迅速，塞拉密封可靠，本发明的十字滑块式塞拉门机构，能满足上述门的开关与塞拉运动，但与上述多家机构有较大的区别，而且结构更加简单可靠，成本低廉，为塞拉门降低成本，增加可靠度提供了保证。The high-speed train sliding door is used for the switch and sealing of the door of the subway or high-speed train. It is mainly required to open and close the door quickly, and the plug seal is reliable. The cross slider type plug door mechanism of the present invention can meet the above-mentioned door opening and closing and plug movement, but it is quite different from the above-mentioned many mechanisms, and the structure is simpler Reliable and low in cost, it provides a guarantee for reducing the cost and increasing the reliability of the sliding door.
本发明结合了各家的长处，克服了各家的不足形成一种新十字滑块式的塞拉机构，使塞拉门运动更加可靠，尺寸更加紧凑，同时也降低成本，增加塞拉门运动的可靠度。The present invention combines the strengths of each company, overcomes the shortcomings of each company, and forms a new cross-slider type plug mechanism, which makes the sliding door more reliable in movement and more compact in size, and also reduces costs and increases the sliding door movement. reliability.
