Description

电动行李舱门 技术领域
本发明涉及电动行李舱门。
背景技术
传统大巴气动行李舱门体需气缸主驱动转轴，气弹簧为辅，从而带动摆臂运动，驱使行李舱门体的上升与关闭。控制箱在行李舱内部，占据空间。其次大巴气动行李舱门体在关闭之后，门锁的锁芯与锁扣的连接处于一级锁位置，再需要进一步拉紧舱门体，使门锁的锁芯与锁扣进入二级锁位置，即上了二级锁，这样才能保证门锁始终处于锁紧状态，由于拉紧机构采用气缸，气缸依然通过控制转轴依旧紧紧将舱门体向里拉，一直保持紧拉状态，长时间的紧拉，会造成舱门体周围密封条变形，甚至会造成舱门体变形，影响舱门的正常使用。
发明内容
本发明的目的在于提出一种结构简单、具有良好开关性能的电动行李舱门。
为达到上述目的，本发明采取如下技术方案：本发明具有框架和舱门体，舱门体处于框架的前侧，框架的左右两侧上部近舱门体各固定有轴承座，两轴承座支承一转轴，转轴的两端各固定有呈弯曲状的摆臂，摆臂的端部动连接在舱门体的背面中部，框架顶部的左右两侧各动连接有舱门体电动撑杆和第一气弹簧，舱门体电动撑杆与第一气弹簧具有相同倾斜度且相平行，每侧的舱门体电动撑杆和第一气弹簧的端部均动连接在同侧摆臂的顶面，框架的左右两侧的中部各动连接有第二气弹簧，第二气弹簧的端部动连接在同侧摆臂的侧面；舱门体的左右两侧各设有至少一把门锁，框架的左右两侧各设有门锁拉紧机构。
框架的左右两侧的中部各动连接有呈弯曲状的支撑杆，支撑杆的端部动连接在舱门体背面的下部。
所述舱门体的左右两侧各设有两把所述门锁，与各门锁的锁芯相配合的第一锁扣安装在框架的对应部位上。
所述两门锁拉紧机构各具有固定在框架上的固定架、中部铰接在固定架上的两根摆杆、铰接在摆杆后端的连杆以及门锁电动撑杆，此外还具有与摆杆一一对应的第二锁扣，第二锁扣安装在舱门体侧面的相应位置上，门锁电动撑杆一端连接在固定架上，另一端连接在连杆上。
舱门体的腔内设有解锁机构，所述解锁机构具有动连接在舱门体腔内上部的转盘，转盘上设有偏离中心的两根上横拉杆和一根竖拉杆，竖拉杆的下端与两个相啮合的齿轮中的其中一齿轮连接，两齿轮各连接一根下横拉杆，两根上横拉杆和两根下横拉杆分别与四个门锁连接。
所述转盘由气缸带动旋转，气缸由电磁阀控制。
本发明具有如下积极效果：1.本发明通过两根舱门体电动撑杆与四个气弹簧就可以完全控制舱门体的上升与关闭，结构简单，安装方便，占据空间小，提高了行李舱的空间使用率；舱门体电动撑杆不受外界温度影响，保证舱门体正常打开与关闭，具有良好开关性能。2.本发明的拉紧机构在舱门锁上二级锁之后，门锁电动撑杆复位，不再对舱门体施力，保护了舱门体，有利进一步提高舱门体的开关性能。3.本发明控制舱门体利用了气弹簧，根据舱门体的重量设计气弹簧伸展的最大长度与力和在完全压缩状态下的最小长度与力，从而选择不同规格的气弹簧。本发明适用任何大小的舱门，适用性强。

具体实施方式
(实施例1)
见图1至图7，实施例1具有框架1、舱门体2、摆臂5、舱门体电动撑杆6、第一气弹簧7、第二气弹簧8、解锁机构11和拉紧机构12。
舱门体2处于框架的前侧。框架1左右两侧上部近舱门体各固定有框架第一支架1-1，框架第一支架1-1上固定有轴承座3，两轴承座3各通过其内的滚动轴承支承一转轴4，转轴4的两端各通过连接夹5-3固定一呈弯曲状的所述摆臂5上，摆臂5的端部动连接在舱门体2中部的门体第一支架2-1上，每摆臂5上近转轴4的一侧固定有顶面支架5-1和侧面支架5-2。
框架1顶部的左右两侧各固定有框架第二支架1-2，每个框架第二支架1-2上动连接有所述舱门体电动撑杆6和第一气弹簧7，舱门体电动撑杆6与第一气弹簧7具有相同倾斜度且相平行，每侧的舱门体电动撑杆6和第一气弹簧7的端部均动连接在同侧摆臂5的顶面支架5-1上。
框架1的左右两侧的中部各固定有框架第三支架1-3，两个框架第三支架1-3上各动连接有所述第二气弹簧8，第二气弹簧8的端部动连接在同侧摆臂5的侧面支架5-2上。框架1的左右两侧的中部各固定有框架第四支架1-4，框架第四支架1-4上动连接有呈弯曲状的支撑杆9，支撑杆9的端部动连接在舱门体2下部的门体第二支架2-2上。
上述所有的动连接均为球型铰链连接。
所述第一、第二气弹簧都是根据舱门体的重量来设计伸展的最大长度与力和在完全压缩状态下的最小长度与力，舱门体电动撑杆和气弹簧的连接位置是根据舱门体的大小、摆臂的旋转角度，舱门最高点的位置以及舱门体电动撑杆和气弹簧规格等参数经计算而决定。
舱门体2的左右两侧各设有至少一把门锁10，门锁的数量是由舱门体的大小决定的，本实施例具有两把门锁10。与各门锁10的锁芯10-2相配合的第一锁扣10-1安装在框架1的对应部位上。
见图2、4、7和图8，所述门锁拉紧机构12为四连杆结构，在框架1的左右两侧各设有所述门锁拉紧机构12。两门锁拉紧机构12各具有固定架12-1、连杆12-3、两根摆杆12-2以及门锁电动撑杆12-4，固定架12-1固定在框架1上，两根摆杆12-2的中部铰接在固定架12-1上，两摆杆12-2的后端与连杆12-3铰接，门锁电动撑杆12-4一端连接在固定架12-1上，另一端连接在连杆12-3上。此外还具有与摆杆12-2一一对应的第二锁扣12-5，第二锁扣12-5安装在舱门体侧面的相应位置上。门锁电 动撑杆12-4一端连接在固定架12-1上，另一端连接在连杆12-3上，由门锁电动撑杆12-4带动连杆12-3运动。框架内且在门锁拉紧机构12的外部设有保护壳12-6。
当门锁电动撑杆12-4收缩，摆杆12-2抵及第二锁扣12-5并向第二锁扣12-5施力，拉动舱门体关闭，门锁电动撑杆12-4复位时，摆杆12-2脱离第二锁扣12-5。
见图1和图6，所述解锁机构11处于舱门体2的腔内，解锁机构11具有由轴动连接在舱门体腔内上部的转盘11-1，转盘11-1上设有偏离中心的两根上横拉杆11-2和一根竖拉杆11-3，竖拉杆11-3的下端与相啮合的两齿轮11-4中的其中一齿轮偏心连接，两根下横拉杆11-5分别与两齿轮11-4偏心连接，两根上横拉杆11-2和两根下横拉杆11-5分别与四个门锁10的锁芯10-2连接。所述转盘11-5由气缸11-6带动旋转，气缸11-6是一种小体积气缸，设置在舱门体2的腔内。气缸11-6由电磁阀控制。解锁时，转盘11-5逆向旋转(图6)，各通过两根上横拉杆11-2拉动对应锁芯中的相关零件动作，同时通过竖拉杆11-3带动其中一齿轮11-4旋转，另一相啮合的齿轮11-4反向旋转，分别通过两根下横拉杆11-5拉动相应锁芯中的相关零件，四个门锁的锁芯10-2均与对应的第一锁扣10-1松开。
可以在上述一齿轮上由连接件连接一个把手11-7，把手11-7处于舱门体2前壁上的窗口中(见图3)，当发生断电应急情况下，可以启动手动解锁。现有大巴电动行李舱系统因为气缸控制滚杆的原因，无法做到手动开关。
舱门在正常关闭状态下，舱门体电动撑杆6、第一气弹簧7初始位置在死点线下方，第二气弹簧8初始位置在死点线上方。
需要打开舱门时，首先解锁机构11动作，启动气缸11-6，完成自动解锁。启动两侧舱门电动撑杆6，舱门电动撑杆6伸长，舱门2向外向上升，舱门电动撑杆6和第一气弹簧7需克服第二气弹簧8的阻力和舱门2的重力，当第二气弹簧8过了死点线之后，第一气弹簧7、第二气弹簧8和舱门电动撑杆6一起克服舱门2的重力将舱门2向上推至最高点。
需要舱门关闭时，舱门电动支撑杆6收缩复位，舱门2自身的重力与舱门电动撑杆6一起克服第一气弹簧和第二气弹簧的阻力，当第二气弹簧8过了死点线之后，舱门电动撑杆6、第一气弹簧8和舱门体2的重力一起克服第一气弹簧7的阻力运动，将舱门体2关闭，此时第一锁扣10-1到达门锁芯内一级锁位置，该位置上设有第一限位开关，第一锁扣10-1触碰到第一限位开关，第一限位开关发出信号，舱门电动撑杆6不再工作，同时启动门锁电动撑杆12-4收缩，连杆12-3带动两摆杆12-2摆动，摆杆12-2各与对应的第二锁扣12-5相抵，同时通过拉动第二锁扣12-5将舱门 体往里拉，当第一锁扣10-1到达二级锁位置，在门锁芯内二级锁位置上设有第二限位开关，第一锁扣10-1触碰到第二限位开关，第二限位开关发出信号，门锁电动撑杆12-4复位，不再对舱门体施力，舱门彻底关闭。
