如图4所示，所述推力测试装置2为测力计，包括拉动弹簧14和连接头15，所述拉动弹簧14与连接头15连接，所述连接头15通过第二转轴16与连杆12连接；所述推力测试装置2中的连接头15还包括伸缩杆连接部21，所述连接头15通过伸缩杆连接部21与伸缩杆24对接。所述伸缩杆连接部21包括圆形的接触头，所述接触头设有第二转轴孔，所述第二转轴16穿过第二转轴孔使所述接触头与连杆12连接；所述伸缩杆24设有对接头22，所述对接头22为圆弧状，与接触头配合，半包在所述接触头外侧，所述对接头22带有磁性，可以和伸缩杆连接部21紧密贴合。
所述噪声测试装置3包括：声音提取器17、远场噪声传声器18、近场噪声传声器19以及数据采集终端；所述声音提取器17、远场噪声传声器18、近场噪声传声器19与数据采集终端连接；所述推力测试装置2与数据采集终端连接。
本实施例想对于实施例1增设了在推力测试装置2的对面增设的伸缩杆24，所述伸缩杆24的主要作用在于：维护连杆12转动的过程，防止本装置在长期使用中推力测试装置2的拉动弹簧14发生变形。当人工拉开门体6时，连杆12发生转动，推力测试装置2拉伸，伸缩杆24在拉动弹簧14的推力下后缩，当门体6自动关闭时，拉动弹簧14回弹，伸缩杆24伸长。本实施例汇总的伸长杆在伸缩的过程中虽然能够起到保护推力测试装置2的作用但是会给门体6的开关造成阻力，因此在测试时，应该进行同拉力的多次试验以抵消伸缩杆24对试验结果造成的影响。
实施例3
一种汽车门锁噪音测试装置，包括：车门模拟装置1、推力测试装置2、伸缩杆24和噪声测试装置3。
所述车门模拟装置1包括：台架4以及设置在所述台架4上的门框5和门体6；所述门框5上下两端设有第一转轴孔，所述门体6上下两端设有第一转轴11，所述第一转轴11穿过第一转轴孔，门体6通过第一转轴11设置在门框5内；所述第一转轴11伸出门框5外并与连杆12连接；所述门框5和门体6设有位置对应的门锁安装位13，其上设置锁扣支架。进一步地，所述第一转轴11穿过所述连杆12，所述门框5上设置加强杆20与穿出连杆12的第一转轴11连接。
如图5所示，所述推力测试装置2为测力计，包括拉动弹簧14和连接头15，所述拉动弹簧14与连接头15连接，所述连接头15通过第二转轴16与连杆12连接。所述推力测试装置2中的连接头15还包括伸缩杆连接部21，所述连接头15通过伸缩杆连接部21与电动伸缩杆24对接，所述电动伸缩杆24与电磁继电器23连接，或者电磁继电器23设置在伸缩杆24内部。所述电磁继电器23与所述推力测试装置2通过无线信号联通，所述伸缩杆连接部21为金属材质。所述伸缩杆连接部21包括圆形的接触头，所述接触头设有第二转轴孔，所述第二转轴16穿过第二转轴孔使所述接触头与连杆12连接；所述伸缩杆24设有对接头22，所述对接头22为圆弧状，与接触头配合，半包在所述接触头外侧。
所述噪声测试装置3包括：声音提取器17、远场噪声传声器18、近场噪声传声器19以及数据采集终端；所述声音提取器17、远场噪声传声器18、近场噪声传声器19与数据采集终端连接；所述推力测试装置2与数据采集终端连接。
本实施例在实施例2的基础上，将伸缩杆24与电磁继电器23相连，或者将电磁继电器23设置在伸缩杆24内部，并采用电动伸缩杆24实现自动伸缩。当电磁继电器23和电动伸缩杆24通电时，电磁继电器23使伸缩杆24的接触头带有磁性，因此伸缩杆24能与推力测试装置2的伸缩杆连接部21紧密贴合。伸缩杆24回缩，推力测试装置2的拉动弹簧14拉长继续弹性势能，同时测试拉力，当拉力到达预定值时，断掉电磁继电器23的电源，此时连接头15失去磁性，连杆12随着拉动弹簧14的回缩，发生转动将门体6关闭。门闭合后安装在门框5和门体6上的门锁锁闭，安装在门框5上的声音提取器17可记录门锁发出的声音，带后期对声音品质进行评估，分别设置在近场和远场的近场传声器和远场传声器用于测试车门噪声的大小程度。推力测试装置2与电磁继电器23无线联接，当弹力到达预设值时，推力测试装置2向电磁继电器23发送信号，自动实现电磁继电器23断电。因此，本实施例能够实现门体6的自动开合，无需人工操作，方便多次重复试验。
本具体实施例仅仅是对本发明的解释，其并不是对本发明的限制，本领域技术人员在阅读完本说明书后可以根据需要对本实施例做出没有创造性贡献的修改，但只要在本发明的权利要求范围内都受到专利法的保护。
