在本发明一实施方式中,所述主体部20为四连杆机构,所述主体部 20还包括设置于上下两侧的第一连杆211和第二连杆212以及设置于左右两侧的第三连杆和第四连杆。其中,所述第一连杆211位于所述主体部20上靠近所述第一驱动件410的一侧,所述第二连杆212位于所述主体部20上靠近所述第二驱动件420的一侧,所述第三连杆位于所述主体部20上对应所述第一悬挂端210的一侧,所述第四连杆位于所述主体部20上对应所述第二悬挂端220的一侧。
以下,进一步说明所述驱动机构的驱动件驱动所述主体部20发生变形,以使得所述底盘10相对所述车轮结构30抬升或降低的驱动方式及工作原理。
第一种驱动方式及工作原理:参见图1所示,所述驱动件包括设置于所述主体部20下方的第一驱动件410以及设置于所述主体部20上方的第二驱动件420。所述主体部20还包括设置于相对两侧的第一连杆211和第二连杆212,所述第一连杆211位于所述主体部20上靠近所述第一驱动件410的一侧,所述第二连杆212位于所述主体部20上靠近所述第二驱动件420的一侧;所述第一驱动件410与所述第一连杆211保持传动连接,并对所述第一连杆211提供第一驱动力,所述第二驱动件420与所述第二连杆212保持传动连接,并对所述第二连杆212提供第二驱动力,以使得所述主体部20变形。
进一步地,所述第一驱动件410包括第一驱动杆411和伸缩设置于所述第一驱动杆411内的第一活动杆412,所述第一驱动杆411与所述底盘10连接,所述第一活动杆412与所述第一连杆211活动连接。所述第二驱动件420包括第二驱动杆421和伸缩设置于所述第二驱动杆421内的第二活动杆422,所述第二驱动杆421与所述底盘10连接,所述第二活动杆422与所述第二连杆212活动连接。
车辆在正常行驶情况下,所述底盘10与所述车轮结构30的相对位置如图1所示。参见图2所示,当所述第一驱动件410的第一驱动杆411 驱动所述第一活动杆412收缩,所述第二驱动件420的第二驱动杆421驱动所述第二活动杆422伸长时,所述第一驱动件410能够对所述第一连杆211提供第一驱动力,所述第二驱动件420能够对所述第二连杆212提供第二驱动力,使所述主体部20向靠近所述第一驱动杆411(也即远离所述第二驱动杆421)的方向移动,进而使所述第一连杆211和第二连杆212向下转动以带动所述主体部20变形,使得所述底盘10与所述车轮结构30之间的高度差增大。而在实际情况中,车辆行驶时所述车轮结构30相对地面的位置是固定的,因此只能通过所述底盘10相较于地面抬升,才能实现所述底盘10与所述车轮结构30之间的高度差增大。
也就是说,在实际情况中,当所述第一驱动件410的第一驱动杆411驱动所述第一活动杆412收缩,所述第二驱动件420的第二驱动杆421驱动所述第二活动杆422伸长时,能够使所述主体部20的第一悬挂端210相对地面向上移动,带动所述主体部20变形,进而使所述底盘10相较于所述车轮结构30抬升。
参见图3所示,当所述第一驱动件410的第一驱动杆411驱动所述第一活动杆412伸长,所述第二驱动件420的第二驱动杆421驱动所述第二活动杆422收缩时,所述第一驱动件410能够对所述第一连杆211提供第一驱动力,所述第二驱动件420能够对所述第二连杆212提供第二驱动力,使所述主体部20向远离所述第一驱动杆411(也即靠近所述第二驱动杆421)的方向移动,进而使所述第一连杆211和第二连杆212向上转动以带动所述主体部20变形,使得所述底盘10与所述车轮结构30之间的高度差减小。而在实际情况中,车辆行驶时所述车轮结构30相对地面的位置是固定的,那么只能通过所述底盘10相较于地面降低,才能实现所述底盘10与所述车轮结构30之间的高度差减小。
也就是说,在实际情况中,当所述第一驱动件410的第一驱动杆411驱动所述第一活动杆412伸长,所述第二驱动件420的第二驱动杆421驱 动所述第二活动杆422收缩时,能够使所述主体部20的第一悬挂端210相对地面向下移动,带动所述主体部20变形,进而使所述底盘10相较于所述车轮结构30降低。
第二种驱动方式及工作原理:在第二种驱动方式中,可以省略所述第二驱动件420,即所述驱动件仅包括设置于所述主体部20下方的第一驱动件410。所述主体部20还包括设置于相对两侧的第一连杆211和第二连杆212,所述第一连杆211位于所述主体部20上靠近所述第一驱动件410的一侧。所述第一驱动件410与所述第一连杆211保持传动连接,并对所述第一连杆211提供第一驱动力,以使得所述主体部20变形。
进一步地,所述第一驱动件410包括第一驱动杆411和伸缩设置于所述第一驱动杆411内的第一活动杆412,所述第一驱动杆411与所述底盘10连接,所述第一活动杆412与所述主体部20的第一连杆211活动连接。
车辆在正常行驶情况下,所述底盘10与所述车轮结构30的相对位置如图1所示。参见图2所示,当所述第一驱动件410的第一驱动杆411驱动所述第一活动杆412收缩时,能够对所述第一连杆211提供第一驱动力使所述主体部20向靠近所述第一驱动杆411的方向移动,进而使所述第一连杆211向下转动以带动所述主体部20变形,使得所述底盘10与所述车轮结构30之间的高度差增大。而在实际情况中,车辆行驶时所述车轮结构30相对地面的位置是固定的,因此只能通过所述底盘10相较于地面抬升,才能实现所述底盘10与所述车轮结构30之间的高度差增大。
也就是说,在实际情况中,当所述第一驱动件410的第一驱动杆411驱动所述第一活动杆412收缩时,能够使所述主体部20的第一悬挂端210相对地面向上移动,带动所述主体部20变形,进而使所述底盘10相较于所述车轮结构30抬升。
参见图3所示,当所述第一驱动件410的第一驱动杆411驱动所述第一活动杆412伸长时,能够对所述第一连杆211提供第一驱动力使所述主体部20向远离所述第一驱动杆411的方向移动,进而使所述第一连杆211向上转动以带动所述主体部20变形,使得所述底盘10与所述车轮结构30之间的高度差减小。而在实际情况中,车辆行驶时所述车轮结构30相对地面的位置是固定的,那么只能通过所述底盘10相较于地面降低,才能实现所述底盘10与所述车轮结构30之间的高度差减小。
也就是说,在实际情况中,当所述第一驱动件410的第一驱动杆411驱动所述第一活动杆412伸长时,能够使所述主体部20的第一悬挂端210相对地面向下移动,带动所述主体部20变形,进而使所述底盘10相较于所述车轮结构30降低。
第三种驱动方式及工作原理:在第三种驱动方式中,可以省略所述第一驱动件410,即所述驱动件仅包括设置于所述主体部20上方的第二驱动件420。所述主体部20还包括设置于相对两侧的第一连杆211和第二连杆212,所述第二连杆212位于所述主体部20上靠近所述第二驱动件420的一侧;所述第二驱动件420与所述第二连杆212保持传动连接,并对所述第二连杆212提供第二驱动力,以使得所述主体部20变形。
进一步地,所述第二驱动件420包括第二驱动杆421和伸缩设置于所述第二驱动杆421内的第二活动杆422,所述第二驱动杆421与所述底盘10连接,所述第二活动杆422与所述主体部20的第二连杆212活动连接。
车辆在正常行驶情况下,所述底盘10与所述车轮结构30的相对位置如图1所示。参见图2所示,当所述第二驱动件420的第二驱动杆421驱动所述第二活动杆422伸长时,能够对所述第二连杆212提供第二驱动力使所述主体部20向远离所述第二驱动杆421的方向移动,进而使所述第二连杆212向下转动以带动所述主体部20变形,使得所述底盘10与所述 车轮结构30之间的高度差增大。而在实际情况中,车辆行驶时所述车轮结构30相对地面的位置是固定的,那么只能通过所述底盘10相较于地面抬升,实现所述底盘10与所述车轮结构30之间的高度差增大。
也就是说,在实际情况中,当所述第二驱动件420的第二驱动杆421驱动所述第二活动杆422伸长时,能够使所述主体部20的第一悬挂端210相对地面向上移动,带动所述主体部20变形,进而使所述底盘10相较于所述车轮结构30抬升。
参见图3所示,当所述第二驱动件420的第二驱动杆421驱动所述第二活动杆422收缩时,能够对所述第二连杆212提供第二驱动力使所述主体部20向靠近所述第二驱动杆421的方向移动,进而使所述第二连杆212向上转动以带动所述主体部20变形,使得所述底盘10与所述车轮结构30之间的高度差减小。而在实际情况中,车辆行驶时所述车轮结构30相对地面的位置是固定的,那么只能通过所述底盘10相较于地面降低,实现所述底盘10与所述车轮结构30之间的高度差减小。
也就是说,在实际情况中,当所述第二驱动件420的第二驱动杆421驱动所述第二活动杆422收缩时,能够使所述主体部20的第一悬挂端210相对地面向下移动,带动所述主体部20变形,进而使所述底盘10相较于所述车轮结构30降低。
在本发明一实施方式中,所述驱动件为气动驱动件。即所述第一驱动件410为气动驱动件,所述第二驱动件420为气动驱动件。由于气动驱动件不会产生互相拉伸和挤压的力,所以可以保证本发明的车辆底盘结构的安全性。需要说明的是,所述驱动件也可以是液压驱动件或其他形式的驱动件,只要保证所述驱动件能够驱动所述主体部20发生变形,以使得所述底盘10相对所述车轮结构30抬升或降低即可。
在本发明一实施方式中,所述车轮结构30和所述主体部20的数量 均为两个,两个所述车轮结构30和两个所述主体部20一一对应地设置于所述底盘10的两侧。
综上所述,本发明的车辆底盘结构,通过所述驱动机构的驱动件驱动所述主体部发生变形,使得所述主体部的第一悬挂端相应地上升或下降,从而带动所述底盘相对所述车轮结构抬升或降低,由此扩大车辆及其模型的应用范围。当车辆在平路上行驶时降低底盘的高度,可以使车辆及其模型的重心降低从而使车辆在高速行驶时具有更好的稳定性。当车辆在野外行驶时抬升底盘的高度,可以使车辆及其模型的重心抬高从而得到更好的越野性能。使车辆同时具备高速行驶和越野行驶的功能,当该车辆用于遥控车时,能够被控制以完成多种行驶动作,如急速转弯、跨越障碍物等等,使得控制更加敏捷、操作更加机动。
本发明实施例还提供一种车辆,包括如上所述的车辆底盘结构1。需要说明的是,在上述实施例和实施方式中关于所述车辆底盘结构1的描述同样适用于本发明的车辆。
在本发明一实施方式中,所述车辆可以为车辆模型或遥控车等。
