目前市面上应用于电动尾门的植绒弹簧都是采用喷胶、静电植绒的方式完成,完成后的弹簧内外侧都被植绒,由于弹簧本体内侧植入的绒毛不仅起不到减摩擦的作用,还增加了弹簧的内外径,对于很多设计空间比较狭小的尾门***,弹簧内外径的增加让弹簧的设计及装配很有困难。
目前市面上应用于电动尾门的植绒弹簧都是采用圆形截面钢丝制作的,但客户均希望弹簧的纵向预留空间尽量小,从而制作重量更轻的电动尾门撑杆***。对于纵向空间比较狭小的尾门***,采用常规的圆形截面的钢丝,很多车型尾门***无法采用植绒弹簧来消除噪音。
目前市面上应用于电动尾门的植绒弹簧都是在底面防锈涂层为电泳漆的表面进行植绒,但是电泳漆产生的废水会带来环境问题,且电泳涂层属于封闭式涂层,一旦被外界划伤,将会很快生锈且逐渐扩散。

本发明在保留传统电动尾门弹簧防锈降噪的基础上,仅在弹簧外表面植绒,避免了在弹簧侧面的植绒,本发明将椭圆形钢丝或者鹅卵形钢丝代替原形钢丝,缩小了弹簧纵向压并高度,使得原本较小的电动尾门***也能使用植绒弹簧,从而解决了噪音的问题。本发明将椭圆形钢丝代替圆形钢丝,缩小了弹簧纵向压并高度,使得原本较小的电动尾门***也能使用植绒弹簧,从而解决了噪音的问题。本发明将锌铝微片防锈涂层代替电泳涂层,大大提高了涂层在常规不被破坏和表面被划伤情况下的防锈能力,同时降低了对环境的污染。

具体实施方式
以下参考说明书附图介绍本发明的多个优选实施例,使其技术内容更加清楚和便于理解。本发明可以通过许多不同形式的实施例来得以体现,本发明的保护范围并非仅限于文中提到的实施例。

实施例一
为改善传统内外表面及侧面均植绒的电动尾门弹簧,需要更大的安装空间,导致很多空间有限的电动尾门***不能使用植绒弹簧来达到降噪的效果,针对当前植绒弹簧,本发明设计了一种可在小空间内安装的植绒弹簧方案,且在相同安装空间的情况下,弹簧剪切应力可以做的更低,疲劳寿命更高。
本发明的主要技术方案如下:
如图1和图3所示,本发明植绒弹簧包括弹簧本体1、电泳涂层4、弹簧外表面植绒层2,弹簧本体1决定弹簧在***内的力学性能及疲劳寿命,电泳涂层4决定弹簧的防腐蚀能力,弹簧外表面植绒层2,通过在胶水层5上植绒绒毛6,隔绝了弹簧本体1金属和弹簧外管直接摩擦,消除了弹簧本体与外管摩擦而产生的摩擦噪音。
本发明植绒弹簧,打破了传统的在整个弹簧内外表面均植绒的思想,避免了在弹簧侧面植绒,仅在弹簧外表面植绒,从而当弹簧完全压并时,压并高度大大减小,使得本来装不进***的弹簧可以在现有空间安装了,在不改变***结构的前提下,实现了植绒降噪。
本发明植绒弹簧,打破了传统的在整个弹簧表面均植绒的思想,避免了在弹簧内表面植绒,仅在弹簧外表面植绒,从而在相同的***安装空间下,可以增大弹簧的钢丝直径,降低弹簧剪切应力,从而提高弹簧的疲劳寿命。
本发明的加工方法如下:计算好弹簧的并紧高度(弹簧并紧对应钢丝之间间隙为零的状态)后,根据并紧高度,制作弹簧专用夹具,以及与夹具相对应的压缩设备,该夹具包括一个金属插销、一根带插销孔的不锈钢管、一个与不锈钢管焊接相连的固定金属块、一个带孔的金属块,金属管的直径与弹簧内经相匹配,插销孔到固定金属块的距离为弹簧的并紧高度。先将夹具的金属管和焊接在金属管上的金属块安装在压缩设备上,然后将弹簧装入金属管,再将带孔的金属块装入金属管,启动压缩设备,先将弹簧压缩到完全并紧的状态,再将插孔***插销孔,然后释放压缩装置,取下包含已经被压并弹簧的夹具。
弹簧压好后,将夹具和弹簧一起放入植绒设备,由于弹簧被压并,弹簧内表面和侧面可以不被植绒,仅在弹簧外表面可以被植绒,植绒完成后,把夹具再次装入压缩设备,将弹簧释放开,于是得到仅外表面被植绒的弹簧。
实施例二
为改善传统圆形钢丝制作的电动尾门弹簧,需要更大的安装空间,导致很多空间有限的电动尾门***不能使用植绒弹簧来达到降噪的效果,针对当前植绒弹簧,本发明设计了一种可在小空间内安装的植绒弹簧方案,且在相同的***安装空间的情况下,弹簧剪切应力可以做的更低,疲劳寿命更高。本发明的主要技术方案如下:
如图1、图2和图3所示,本发明植绒弹簧包括弹簧本体1、电泳涂层4、弹簧表面植绒层2,弹簧本体1决定弹簧在***内的力学性能及疲劳寿命,电泳涂层4决定弹簧的防腐蚀能力,弹簧表面植绒层2,通过在胶水层5上植绒绒毛6,隔绝了弹簧本体1金属和弹簧外管直接摩擦,消除了弹簧本体1与外管摩擦而产生的摩擦噪音。
本发明植绒弹簧,打破了传统的用圆形钢丝制作的电动尾门弹簧的思想,采用椭圆形钢丝或鹅卵形钢丝,从而当弹簧完全压并时,压并高度大大减小,使得本来装不进***的弹簧可以在现有空间安装了,在不改变***结构的前提下,实现了植绒降噪。
本发明植绒弹簧,打破了传统的用圆形钢丝制作的电动尾门弹簧的思想,采用椭圆形钢丝,从而在相同的安装空间下,可以增大弹簧的钢丝直径,降低弹簧剪切应力,从而提高弹簧的疲劳寿命。
本发明的方案如下:依据客户定义的***边界条件,使用常规圆形钢丝设计弹簧,然后将依据圆形钢丝的直径通过截面积的等效转换,转换成相同截面积的椭圆形钢丝,从而得到一个弹簧并紧高度(此状态对应钢丝之间间隙为零)大大减小的弹簧方案,于是原本由于纵向空间小而不能采用植绒来降低噪音的电动尾门***,在不改变任何参数的情况下,解决了噪音的问题。
实施例三
为改善传统电泳植绒电动尾门弹簧,经常会因电泳涂层的碰伤而减弱盐雾效果,导致很多电动尾门***的寿命受到弹簧盐雾能力的限制,针对当前电泳植绒弹簧,本发明设计了一种防锈能力更好,更加环保的底面防锈涂层,即使有外力引起涂层表面被划伤,也有自保护功能而不被腐蚀,本发明的主要技术方案如下:
如图1、图4所示,本发明植绒弹簧包括弹簧本体1、锌铝微片涂层7、弹簧表面植绒涂层2,弹簧本体1决定弹簧在***内的力学性能及疲劳寿命,锌铝微片涂层7决定弹簧的防腐蚀能力,弹簧表面植绒涂层2,通过在胶水层5植绒绒毛6,隔绝了弹簧本体金属和弹簧外管直接摩擦,消除了弹簧本体与外管摩擦而产生的摩擦噪音。
本发明植绒弹簧,打破了传统的电泳植绒弹簧的思想,避免了使用电泳涂层4,有涂层被划伤而损害盐雾效果的可能性,采用锌铝微片涂层7作为底面防锈涂层,大大提高了涂层表面正常不被碰伤和意外被划伤后的防腐蚀效果,使得本来因弹簧防锈能力不够而必须提前更换整个电动尾门***的问题得到了解决,提高了电动尾门***的寿命。
本发明植绒弹簧,打破了传统的电泳植绒的思想,避免了在弹簧表面采用电泳涂层作为唯一的防锈涂层,且该涂层的整个工艺,产生较多的废水、废气和废渣,而对环境产生污染,而锌铝微片涂层是一种在弹簧表面浸涂或者喷涂锌铝微片涂料,更加环保,且易加工。
本发明的加工方法如下:对弹簧本体1进行抛光预处理后,直接投入锌铝微片涂层7加工线,通过先浸涂或喷涂,然后烘烤的工艺,完成锌铝微片涂层7,然后将做好锌铝微片涂层7的弹簧,投入后续植绒涂层2生产线,通过上胶、植绒和烘干完成植绒涂层,于是得到一种既有较强防腐蚀能力且能消除***噪音的锌铝植绒弹簧。
以上详细描述了本发明的较佳具体实施例。应当理解,本领域的普通技术无需创造性劳动就可以根据本发明的构思作出诸多修改和变化。因此,凡本技术领域中技术人员依本发明的构思在现有技术的基础上通过逻辑分析、推理或者有限的实验可以得到的技术方案,皆应在由权利要求书所确定的保护范围内。
